Hexavalent chromium [Cr(VI)] exposure increases the risk of cancer occurrence. This study found that the levels of an atypical methyltransferase, METTL16 were greatly upregulated in the cells, and mouse tissues with Cr(VI) exposure, and played a critical role in cell proliferation and tumor growth induced by Cr(VI). Similarly, we found METTL16 was upregulated in various human cancer tissues. To understand mechanism of METTL16 in inducing carcinogenesis and cancer development, we identified that glutamate-ammonia ligase (GLUL) as the METTL16 functional target for regulating glutamine metabolism and tumorigenesis induced by Cr(VI) exposure. We demonstrated that METTL16 promoted GLUL expression in a m6A-dependent manner. Furthermore, METTL16 methylated the specific stem-loop structure of GLUL transcript, thereby increased the recognition and splicing of pre-GLUL RNA modified site by m6A reader YTHDC1, which ultimately accelerated the production of mature GLUL mRNA. Animal model of Cr(VI) exposure further confirmed that the expression levels of METTL16 and GLUL were both significantly induced in vivo, and there had a significant positive correlation between METTL16 and GLUL levels. Furthermore, we found that YTHDC1 was also important in inducing GLUL expression, and MYC was the upstream mediator of METTL16 to increase its transcriptional activation. Our study revealed new mechanism of metal carcinogenesis and cancer development., Competing Interests: Declaration of Competing Interest The authors declare that they have no competing interests., (Copyright © 2024 The Authors.

Activin A, a member of the transforming growth factor β (TGF-β) superfamily, is involved in tumorigenesis and tumor progression. However, it remains unclear whether activin A can affect the migration of lung adenocarcinoma (LUAD) cells. In this study, the results of differentially expressed genes (DEGs) identification revealed that lung adenocarcinoma tissues exhibited lower expression of activin βA mRNA, but higher expression of epidermal growth factor (EGF) and MMP9 mRNA compared to nontumor tissues. Moreover, we found that activin A inhibited human LUAD A549 cell proliferation promoted by EGF. Additionally, EGF induced A549 cell migration in microfluidic device, while activin A attenuated EGF actions. Simultaneously, EGF increased the levels of migration-related proteins, but activin A played the opposite role. Furthermore, the study revealed that EGF upregulated the ratio of p-ERK/ERK in A549 cells, which was weakened by activin A, and A549 cell migration regulated by activin A was not related to calcium signaling. In addition, the inhibitory effect of activin A on EGF-induced A549 cell migration was attenuated by the ERK inhibitor FR180204. These findings demonstrate that activin A effectively hinders the migration of A549 cells induced by EGF through ERK1/2 signaling, suggesting that targeting activin A may hold promise in the treatment of EGF-dependent LUAD growth and metastasis., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Introduction: Determining lines of therapy (LOT) using real-world data is crucial to inform clinical decisions and support clinical research. Existing rules for determining LOT in patients with metastatic non-small cell lung cancer (mNSCLC) do not incorporate the growing number of targeted therapies used in treatment today. Therefore, we propose rules for determining LOT from real-world data of patients with mNSCLC treated with targeted therapies., Methods: LOT rules were developed through expert consensus using a real-world cohort of 550 patients with ALK+ or ROS1+ mNSCLC in the multi-institutional, electronic medical record-based Academic Thoracic Oncology Medical Investigators Consortium's (ATOMIC) Driver Mutation Registry. Rules were subsequently modified based on a review of appropriate LOT determination. These resulting rules were then applied to an independent cohort of patients with EGFR+ mNSCLC to illustrate their use., Results: Six rules for determining LOTs were developed. Among 1133 patients with EGFR mutations and mNSCLC, a total of 3168 regimens were recorded with a median of 2 regimens per patient (IQR, 1-4; range, 1-13). After applying our rules, there were 2834 total LOTs with a median of 2 LOTs per patient (IQR, 1-3; range, 1-11). Rules 1-3 kept 11% of regimen changes from advancing the LOT. When compared to previously published rules, LOT assignments differed 5.7% of the time, mostly in LOTs with targeted therapy., Conclusion: These rules provide an updated framework to evaluate current treatment patterns, accounting for the increased use of targeted therapies in patients with mNSCLC, and promote standardization of methods for determining LOT from real-world data., (© 2024 The Author(s).

Small cell lung cancer (SCLC) is an aggressive neuroendocrine tumor characterized by a high metastatic potential with an overall survival rate of ~5%. The transcription factor signal transducer and activator of transcription 3 (STAT3) is overexpressed by >50% of tumors, including SCLC, but its role in SCLC development and metastasis is unclear. Here, we show that, while STAT3 deletion restricts primary tumor growth, it paradoxically enhances metastatic spread by promoting immune evasion. This occurs because STAT3 is crucial for maintaining the immune sensor stimulator of interferon (IFN) genes (STING). Without STAT3, the cyclic adenosine monophosphate-guanosine monophosphate synthase-STING pathway is inactive, resulting in decreased type I IFN secretion and an IFN gene signature. Importantly, restoration of IFN signaling through re-expression of endogenous STING, enforced expression of IFN response factor 7 or administration of recombinant type I IFN re-established antitumor immunity, inhibiting metastatic SCLC in vivo. These data show the potential of augmenting the innate immune response to block metastatic SCLC., Competing Interests: Competing interests: The authors declare no competing interests., (© 2024.

Introduction: Immune checkpoint inhibitors (ICIs) plus chemotherapy is now a standard treatment for non-small cell lung cancer (NSCLC). Whether ICI plus chemotherapy (ICI-chemo) or ipilimumab plus nivolumab (I-N)-based therapy is superior for patients with NSCLC with a programmed death-ligand 1 (PD-L1) tumor proportion score (TPS) of 1-49 % has not been evaluated., Methods: This multicenter retrospective study included NSCLC patients with a TPS score of 1-49 %, who began first-line chemotherapy. Propensity score matching analysis was used to adjust for various confounders and evaluate treatment efficacy., Results: A total of 401 patients were enrolled, of whom 308 received ICI-chemo and 93 received I-N-based therapy. The median OS was 21.0 months in the ICI-chemo group and 20.0 months in the I-N-based therapy group. After propensity score matching, there was no difference in OS or PFS between the ICI-chemo group and the I-N-based therapy group (OS: hazard ratios (HR), 0.83; 95 % confidence interval [CI], 0.54-1.26, PFS: HR, 0.72; 95 % CI, 0.52-1.00). Among PD-L1 TPS 25-49 %, there was a tendency for OS to be favorable for the ICI-chemo group (OS: HR, 0.30; 95 % CI, 0.09-0.85). Treatment discontinuation occurred for 26.2 % of the patients in the ICI-chemo group and 41.9 % in the I-N-based therapy group., Conclusions: Among PD-L1 TPS 1-49 %, there was no significant difference in survival outcomes between the ICI-chemo group and the I-N-based therapy group. Based on the results of a subgroup analysis, ICI-chemo may be superior for treating NSCLC with a TPS of 25-49 %., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Dr. Tanaka reported receiving lecture fees from AstraZeneca K.K, Chugai Pharmaceutical Co., Boehringer-Ingelheim Japan Inc., Ono Pharmaceutical Co., Pfizer Japan Inc., and Bristol-Meyers Squibb.

Abstract: Tumor-to-tumor metastasis is extremely rare. We herein describe a 67-year-old woman who underwent FDG PET/CT for initial staging of lung cancer. This imaging examination revealed a pelvic mass with peripheral FDG uptake, suggesting a metastatic tumor from lung cancer or a secondary malignancy. Examination of a surgical specimen confirmed metastatic lung adenocarcinoma within a struma ovarii, suggesting tumor-to-tumor metastasis., Competing Interests: Conflicts of interest and sources of funding: none declared., (Copyright © 2024 Wolters Kluwer Health, Inc.

About one third of patients with Non-Small Cell Lung Cancer (NSCLC) presents at diagnosis with localized or locally advanced disease amenable to curative surgical resection. Surgical operability refers to stage I to IIIA and selected stage IIIB NSCLC. One of the main challenges in the management of early-stage resectable NSCLC is the optimization of available therapeutic strategies to prevent local and distant disease relapse, thus improving survival outcomes. There is evidence supporting the clinical use of both adjuvant and neoadjuvant immunotherapy-based strategies for resected/resectable, stage IB-IIIA NSCLC. Available data from randomized phase III trials have led to the incorporation of several immune checkpoint blockers (ICBs) into the international guidelines for early-stage NSCLC. Preclinical rationale of targeting specific subsets of T-cells by acting early on immune checkpoint receptors (e.g., PD-(L)1 and CTLA-4) is strong. Recent evidence is in favor of the neoadjuvant approach alone or as a part of perioperative strategy, demonstrating survival benefit. Combining neoadjuvant chemotherapy and immunotherapy before surgery results in both pathologic complete response (pCR) and major pathologic response (MPR) improvement, and survival outcomes, with no major safety issues. In this review, we summarize the rationale behind neoadjuvant/perioperative immunotherapy strategies and, due to the clinical relevance of immunotherapy in resectable NSCLC, we provide current evidence of this cutting-edge approach among special populations including older adults, women, and oncogene addicted NSCLC. To conclude, we present future perspectives in the use of immunotherapy for operable NSCLC with a special focus on novel investigational combinations underway., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier Ltd.

Introduction: Small cell transformation (SCT) is a typical mechanism of adaptive resistance to third generation epidermal growth factor receptor inhibitors (EGFRi) which have become the standard of care for EGFR-driven non-small cell lung cancer (EGFR+ NSCLC). Little is known about the optimal management of SCT patients. This study aimed to compare outcomes under platinum/etoposide chemotherapy alone (chemo) or in combination with EGFR inhibitors (EGFRi+chemo) or immune checkpoint inhibitors (ICI+chemo). In addition, DLL3 expression was explored as potential novel therapeutic target., Methods: We conducted a retrospective study on patients with EGFR+ NSCLC and SCT treated at 19 centers in Europe and the United States. A total of 47 patients were included of whom 17 received chemo, 20 ICI+chemo, and 10 EGFRi+chemo. We analyzed DLL3 expression by immunohistochemistry., Results: In the entire cohort, median overall survival (OS) from start of first SCT therapy was 11 months (95 % confidence interval [95 %CI] 9.1-12.9) and median progression-free survival (PFS) was 5 months (95 %CI 4.2-5.8). Median PFS was similar in all three groups (chemo and ICI+chemo 4 months, EGFRi+chemo 6 months), and 12-months PFS was 12 % (95 %CI 2 %-31 %), 13 % (95 %CI 0 %-43 %), and 0 % for ICI+chemo, EGFRi+chemo, and chemo, respectively. Median OS in the ICI+chemo group was 13 months (95 %CI 5.5-20.5) compared to 10 months (95 %CI 7.6-12.4) with chemo and EGFRi+chemo (95 %CI 8.1-11.9), respectively. Before and after SCT, 0 % and 93 % of tumors were DLL3-positive., Conclusions: Our results suggest that ICI+chemo and DLL3-targeting agents are worth further exploration in EGFR+ NSCLC undergoing SCT., Presented Elsewhere: Part of this work has been presented at ESMO annual meeting in Madrid, Spain in October 2023 (Poster 1336 P)., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Allgäuer, M received speaker fees from Boehringer Ingelheim.

Background and Purpose: Radiotherapy (RT) in non-small cell lung cancer (NSCLC) can induce cardiac adverse events, including atrial fibrillation (AF), despite advanced RT. This study integrates patient-specific information to develop learning-based models to predict the incidence of AF following NSCLC chemoradiotherapy (CRT) and evaluates these models using institutional and external datasets., Materials and Methods: Institutional and external patient cohorts consisted of 321 and 187 NSCLC datasets who received definitive CRT, including 17 and 6 AF incidences, respectively. The network input had 159 features with clinical, dosimetry, and diagnostic. The class imbalance was mitigated by synthetic minority oversampling technique. To handle various types of input features, machine learning-based model adopted an intervention technique that chose one feature with the largest weight at each dosimetry sub-group in feature selection process, while deep learning-based model employed a hybrid architecture assigning different types of networks to corresponding input paths. Performance was assessed by area under the curve (AUC). The key features were investigated for the machine and deep learning-based models., Results: The hybrid deep learning model outperformed the machine learning-based algorithm in internal validation (AUC: 0.817 vs. 0.801) and produced more consistent performance in external validation (AUC: 0.806 vs. 0.776). Importantly, maximum dose to heart and sinoatrial node (SAN) were found to be the key features for both learning-based models in external and internal validations., Conclusions: The learning-based predictive models showed consistent prediction performance across internal and external cohorts, identifying maximum heart and SAN dose as key features for the incidence of AF., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

The American Cancer Society National Lung Cancer Roundtable strategic plan for provider engagement and outreach addresses barriers to the uptake of lung cancer screening, including lack of provider awareness and guideline knowledge about screening, concerns about potential harms from false-positive examinations, lack of time to implement workflows within busy primary care practices, insufficient infrastructure and administrative support to manage a screening program and patient follow-up, and implicit bias based on sex, race/ethnicity, social class, and smoking status. Strategies to facilitate screening include educational programming, clinical reminder systems within the electronic medical record, decision support aids, and tools to track nodules that can be implemented across a diversity of practices and health care organizational structures. PLAIN LANGUAGE SUMMARY: The American Cancer Society National Lung Cancer Roundtable strategic plan to reduce deaths from lung cancer includes strategies designed to support health care professionals, to better understand lung cancer screening, and to support adults who are eligible for lung cancer screening by providing counseling, referral, and follow-up., (© 2024 The Authors.

Lung cancer in women is a modern epidemic and represents a global health crisis. Cigarette smoking remains the most important risk factor for lung cancer in all patients and, among women globally, rates of smoking continue to increase. Although some data exist supporting sex-based differences across the continuum of lung cancer, there is currently a dearth of research exploring the differences in risk, biology, and treatment outcomes in women. Consequently, the American Cancer Society National Lung Cancer Roundtable recognizes the urgent need to promote awareness and future research that will close the knowledge gaps regarding lung cancer in women. To this end, the American Cancer Society National Lung Cancer Roundtable Task Group on Lung Cancer in Women convened a summit undertaking the following to: (1) summarize existing evidence and identify knowledge gaps surrounding the epidemiology, risk factors, biologic differences, and outcomes of lung cancer in women; (2) develop and prioritize research topics and questions that address research gaps and advance knowledge to improve quality of care of lung cancer in women; and (3) propose strategies for future research. PLAIN LANGUAGE SUMMARY: Lung cancer is the leading cause of cancer mortality in women, and, despite comparatively lower exposures to occupational and environmental carcinogens compared with men, disproportionately higher lung cancer rates in women who ever smoked and women who never smoked call for increased awareness and research that will close the knowledge gaps regarding lung cancer in women., (© 2024 The Author(s).

More than a decade has passed since researchers in the Early Lung Cancer Action Project and the National Lung Screening Trial demonstrated the ability to save lives of high-risk individuals from lung cancer through regular screening by low dose computed tomography scan. The emergence of the most recent findings in the Dutch-Belgian lung-cancer screening trial (Nederlands-Leuvens Longkanker Screenings Onderzoek [NELSON]) further strengthens and expands on this evidence. These studies demonstrate the benefit of integrating lung cancer screening into clinical practice, yet lung cancer continues to lead cancer mortality rates in the United States. Fewer than 20% of screen eligible individuals are enrolled in lung cancer screening, leaving millions of qualified individuals without the standard of care and benefit they deserve. This article, part of the American Cancer Society National Lung Cancer Roundtable (ACS NLCRT) strategic plan, examines the impediments to successful adoption, dissemination, and implementation of lung cancer screening. Proposed solutions identified by the ACS NLCRT Implementation Strategies Task Group and work currently underway to address these challenges to improve uptake of lung cancer screening are discussed. PLAIN LANGUAGE SUMMARY: The evidence supporting the benefit of lung cancer screening in adults who previously or currently smoke has led to widespread endorsement and coverage by health plans. Lung cancer screening programs should be designed to promote high uptake rates of screening among eligible adults, and to deliver high-quality screening and follow-up care., (© 2024 The Author(s).

Background: Immunotherapy in combination with chemotherapy is first-line treatment for patients with extensive-stage small-cell lung cancer (ES-SCLC). Growing evidence suggests that radiation, specifically stereotactic body radiation therapy (SBRT), may enhance the immunogenic response as well as cytoreduce tumor burden. The primary objective of the study is to determine the progression free survival for patients with newly diagnosed ES-SCLC treated with combination multisite SBRT and chemo-immunotherapy (carboplatin, etoposide, and durvalumab)., Methods: This is a multicenter, single arm, phase 2 study. Patients with treatment-naïve, ES-SCLC will be eligible for this study. Patients will receive durvalumab 1500mg IV q3w, carboplatin AUC 5 to 6 mg/mL q3w, and etoposide 80 to 100 mg/m2 on days 1 to 3 q3w for four cycles, followed by durvalumab 1500mg IV q4w until disease progression or unacceptable toxicity. Ablative radiation will be delivered 1 to 4 extracranial sites in 3 or 5 fractions, determined by location, during cycle 2. The primary endpoint is progression-free survival, measured from day 1 of chemoimmunotherapy. Secondary endpoints include grade ≥3 toxicity by CTCAE v5.0 within three months of RT, overall survival, response rate, time to second line systemic therapy, and time to new distant progression., Conclusions: Now that immunotherapy is an established part of ES-SCLC management, it is important to further optimize its use and effect. This study will investigate the progression-free survival of combined SBRT and chemo-immunotherapy in patients with ES-SCLC. In addition, the data from this study may further inform the immunogenic role of SBRT with chemo-immunotherapy, as well as identify clinical, biological, or radiomic prognostic features., (Copyright © 2024 The Authors.

The A disintegrin and metalloprotease (ADAM) family is involved in many vital cellular events, from proliferation to migration, and accumulated evidence suggests its increased expression in malignant tumors. In this study, we investigated ADAM17 expression in non-small cell lung cancer (NSCLC) and its relationship with clinicopathological factors and survival. Immunohistochemical staining of ADAM expression was performed in 108 patients with NSCLC and in 54 control cases with no known malignant diagnosis. Association between ADAM17 expression, clinicopathological factors, and survival were analyzed. The Kaplan-Meier method was used for survival analysis. ADAM17 was lowly expressed in 89 (82.4%) and highly expressed in 19 (17.6%) of the patients with NSCLC. In univariate analysis, high ADAM17 expression, lymphovascular invasion, stage, and treatment response significantly affected progression-free survival (PFS) and overall survival (OS) (p < 0.05). Multivariate analysis also showed that high ADAM17 expression, lymphovascular invasion, stage, and treatment response were important prognostic factors for PFS and OS (p < 0.05). Our study revealed that high ADAM17 expression significantly associated with OS and PFS in patients with NSCLC. ADAM17 may potentially be the area of a new targeted treatment strategy in NSCLC. Thus, routine evaluation of ADAM17 expression in patients with NSCLC may be a future consideration., Competing Interests: Declaration of conflicting interestsThe author(s) declared no potential conflicts of interest with respect to the research, authorship, and/or publication of this article.

Background: The PACIFIC trial established durvalumab administration after chemoradiotherapy as the standard of care for unresectable locally advanced nonsmall cell lung cancer (LA-NSCLC). However, the efficacy and safety of durvalumab in elderly patients aged 75 years or above remains unclear. This study aimed to investigate the real-world efficacy and safety of durvalumab for LA-NSCLC, with a specific focus on elderly patients., Patients and Methods: We reviewed 214 patients who received durvalumab out of 278 patients with unresectable LA-NSCLC who underwent chemoradiotherapy at 7 institutions between July 2018 and March 2022. Propensity score matching (PSM) analysis was performed to evaluate the efficacy of durvalumab in elderly patients., Results: The 2-year progression-free survival (PFS) and 2-year overall survival (OS) rates were 42.2% (95% confidence interval [CI], 34.7%-49.5%) and 77.1% (95% CI, 70.1-82.7%), respectively. Grade ≥ 3 immune-related adverse events (irAEs) occurred in 8.2% of patients. PSM analysis revealed that OS was significantly shorter in elderly patients (≥ 75 years) than in younger patients (< 75 years) (hazard ratio [HR]; 95% CI, 1.39-8.99; P = .008), whereas PFS did not differ significantly between the 2 groups (HR: 1.50, 95% CI, 0.84-2.68, P = .169). The frequency of irAEs did not differ between these groups., Conclusions: The real-world efficacy and safety of durvalumab administration following chemoradiotherapy for LA-NSCLC coincided with the PACIFIC trial's findings. Disease control achieved with this protocol did not differ significantly between elderly and younger patients but had acceptable tolerability, demonstrating its benefit even in elderly LA-NSCLC patients aged 75 years or above., Competing Interests: Disclosure Kenta Murotani received honoraria from Chugai Pharmaceutical Co., Ltd and AstraZeneca K.K.

Purpose: MET amplification is a common resistance mechanism to EGFR inhibition in EGFR-mutant non-small cell lung cancer (NSCLC). Several trials showed encouraging results with combined EGFR and MET inhibition (EGFRi/METi). However, MET amplification has been inconsistently defined and frequently included both polysomy and true amplification., Methods: This is a multicenter, real-world analysis in patients with disease progression on EGFR inhibition and MET copy number gain (CNG), defined as either true amplification (MET to centromere of chromosome 7 ratio [MET-CEP7] ≥ 2) or polysomy (gene copy number ≥ 5, MET-CEP7 < 2)., Results: A total of 43 patients with MET CNG were included, 42 of whom were detected by FISH. Twenty-three, 7, and 14 received EGFRi/METi, METi, and SoC, respectively. Patients in the EGFRi/METi cohort exhibited a superior real-world clinical benefit rate, defined as stable disease or better, of 82% (95% confidence interval [CI], 60-95) compared to METi (29%, 4-71) and SoC (50%, 23-77). Median real-world progression-free survival was longer with EGFRi/METi with 9.8 vs. 4.3 months with METi (hazard ratio [HR], 0.19, 95% CI, 0.06-0.57) and 3.7 months with SoC (0.41, 0.18-0.91), respectively. Overall survival was numerically improved. Interaction analysis with treatment and type of CNG (amplification vs. polysomy) suggests that differences were exclusively driven by MET-amplified patients receiving EGFRi/METi (HR for OS, 0.09, 0.01-0.54)., Conclusion: In this real-world study, EGFRi/METi showed clinical benefit over METi and SoC. Future studies should focus on the differential impact of the type of MET CNG with a focus on true MET amplification as predictor of response., Competing Interests: Disclosure F.

Non-small cell lung cancer (NSCLC) is the most prevalent histology type of lung cancer worldwide, accounting for 18% of total cancer-related deaths estimated by GLOBOCAN in 2020. CircRNAs have emerged as potent regulators of NSCLC development. CircRANGAP1 (hsa&#95;circ&#95;0001235/hsa&#95;circ&#95;0063526) is a potential biomarker for NSCLC identified by microarray dataset analysis. Here, we investigated the biological functions of circRANGAP1 in NSCLC development and elucidated the associated competing endogenous RNA (ceRNA) mechanisms. We found that circRANGAP1 expression was upregulated in NSCLC tissues and cells, which was inversely correlated with carcinogenesis and poor clinical outcome of NSCLC patients. CircRANGAP1 knockdown inhibited NSCLC migration by regulating miR-512-5p/SOD2 axis. In conclusion, circRANGAP1 facilitated NSCLC tumorigenesis and development by sponging miR-512-5p to upregulate SOD2 expression. Suppression of circRANGAP1 expression by si-circRANGAP1 treatment could be a strategy to inhibit NSCLC development and metastasis., Competing Interests: Declarations Conflict of interest The authors declare that there is no conflict of interest.

Lung cancer is the leading cause of cancer-related death worldwide, with poor outcomes even for those diagnosed at early stages. Current standard-of-care for most non-small cell lung cancer (NSCLC) patients involves an array of chemotherapy, radiotherapy, immunotherapy, targeted therapy, and surgical resection depending on the stage and location of the cancer. While patient outcomes have certainly improved, advances in highly personalized care remain limited. However, there is growing excitement around harnessing the power of tumor-infiltrating lymphocytes (TILs) through the use of adoptive cell transfer (ACT) therapy. These TILs are naturally occurring, may already recognize tumor-specific antigens, and can have direct anti-cancer effect. In this review, we highlight comparisons of various ACTs, including a brief TIL history, show current advances and successes of TIL therapy in NSCLC, discuss the potential roles for epigenetics in T cell expansion, and highlight challenges and future directions of the field to combat NSCLC in a personalized manner., Competing Interests: Declaration of competing interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2024 Elsevier B.V.

Fundamental changes in intracellular processes, such as overactive growth signaling pathways, are common in carcinomas and are targets of many cancer therapeutics. GRIP and coiled-coil containing 2 (GCC2) is a trans-Golgi network (TGN) golgin maintaining Golgi apparatus structure and regulating vesicle transport. Here, we found an aberrant overexpression of GCC2 in non-small cell lung cancer (NSCLC) and conducted shRNA-mediated gene knockdown to investigate the role of GCC2 in NSCLC progression. shRNA-mediated GCC2 knockdown suppressed NSCLC cell growth, migration, stemness, and epithelial-mesenchymal transition (EMT) in vitro and tumor growth in vivo. In addition, GCC2 knockdown suppressed cancer cell exosome secretion and the oncogenic capacity of cancer cell-derived exosomes. Mechanistically, GCC2 inhibition decreased epidermal growth factor receptor (EGFR) expression and downstream growth and proliferation signaling. Furthermore, GCC2 inhibition compromised Golgi structural integrity in cancer cells, indicating a functional role of GCC2 in regulating intracellular trafficking and signaling to promote lung cancer progression. Together, these findings suggest GCC2 as a potential therapeutic target for the treatment of NSCLC., Competing Interests: Competing interests: The authors declare no competing interests., (© 2024.

The inevitable acquired resistance to osimertinib (AZD9291), an FDA-approved third-generation EGFR tyrosine kinase inhibitor (EGFR-TKI) for the treatment of patients with advanced non-small cell lung cancer (NSCLC) harboring EGFR activating or T790M resistant mutations, limits its long-term clinical benefit. Telomere maintenance via telomerase reactivation is linked to uncontrolled cell growth and is a cancer hallmark and an attractive cancer therapeutic target. Our effort toward understanding the action mechanisms, including resistance mechanisms, of osimertinib has led to the identification of a novel and critical role in maintaining c-Myc-dependent downregulation of hTERT, a catalytic subunit of telomerase, and subsequent inhibition of telomerase/telomere and induction of telomere dysfunction in mediating therapeutic efficacy of osimertinib. Consequently, osimertinib combined with the telomere inhibitor, 6-Thio-dG, which is currently tested in a phase II trial, effectively inhibited the growth of osimertinib-resistant tumors, regressed EGFRm NSCLC patient-derived xenografts, and delayed the emergence of acquired resistance to osimertinib, warranting clinical validation of this strategy to manage osimertinib acquired resistance., (© 2024 Chen et al.)

Objective: Genetic susceptibility to lung cancer is the subject of extensive research. We investigated whether polymorphisms in the microsomal epoxide hydrolase (EPHX1) gene is linked to lung cancer susceptibility in Jordanian patients., Methods: In this case-control study a total of 218 subjects from Jordan University Hospital and King Hussein Cancer Center were screened (108 lung cancer patients and 110 matched controls). Polymerase chain reaction-restriction fragment-length polymorphism (PCR-RFLP) was used to detect the two common polymorphisms in EPXH1 located in exons 3 and 4; namely, amino acid substitution from tyrosine to histidine at residue 113 of exon 3 (Tyr113His; low activity allele) and amino acid substitution from histidine to arginine at residue 139 of exon 4 (His139Arg; high activity allele)., Results: There was no significant difference in genotype distribution between control subjects and lung cancer patients. In addition, no differences were found when evaluated according to age, gender or tobacco consumption. For exon 3 the adjusted OR was 0.970 (95% CI 0.473 - 1.991) for the Tyr113/His113 genotype and 0.692 (95% CI 0.301 - 1.590) for the Tyr113/Tyr113 genotype, respectively.  For exon 4 the adjusted OR was 0.596 (95% CI 0.297-1.197) for the His139/Arg139 genotype and 0.882 (95% CI 0.117- 6.660) for the Arg139/Arg139 genotype, respectively. Logistic regression analysis did not show differences in EPXH1 distributions between patients and controls when categorized according to predicted microsomal epoxide hydrolase activity.  Therefore, common polymorphisms within EPHX1 do not appear to be significant risk factors for lung cancer development in the Jordanian population., Conclusion: No associations were observed between lung cancer risk and EPXH1 polymorphisms in the Jordanian population.

Background and Objectives : In this study, we evaluated the impact of seven immune indexes on treatment response and survival outcomes in advanced non-small-cell lung cancer (NSCLC) patients receiving second-line and subsequent nivolumab treatment under real-life conditions. Materials and Methods : The pan-immune inflammation value (PIV), systemic immune inflammation value (SII), neutrophil-to-lymphocyte ratio (NLR), platelet-to-lymphocyte ratio (PLR), monocyte-to-lymphocyte ratio (MLR), derived neutrophil-to-lymphocyte ratio (d-NLR), and prognostic nutritional index (PNI) were calculated. All immune indexes were classified as low and high based on cut-off values. Kaplan-Meier and Cox hazard models were used for survival analysis. Results : The median follow-up was 22.0 months (6.0-96.0). The median overall survival (OS) was 30.0 months and the median progression-free survival (PFS) was 7.0 months. In the univariate analysis, comorbidity ( p = 0.03) and nivolumab use for more than eight cycles ( p < 0.0001) were associated with an increase in PFS, while smoking history ( p < 0.005) and d-NLR ( p < 0.05) were more effective regarding OS. Patients who received more than eight cycles of nivolumab had longer median PFS (4 vs. 19 months, p < 0.001) and OS (23 vs. 43 months, p < 0.001). We found longer median OS in the PLR (45.7 vs. 75.4 months; p = 0.05), PIV (53.0 vs. 66.4 months; p = 0.19), SII (50.0 vs. 71.9 vs. months, p = 0.19), and NLR (49.9 vs. 74.55 months, p = 0.10) indexes in nivolumab long-term users (high vs. low groups, respectively). In short-term users of nivolumab, only d-NLR median OS (high vs. low, 19 vs. 75.2 months, p = 0.07) was different. Complete and partial response rates to nivolumab treatment were higher in the PNI-high group ( p = 0.04). Conclusions : In these real-life data, we determined that the PLR, PIV, SII, and NLR indexes were effective in the prognosis of patients who received PD1 inhibitor nivolumab for a long time, and the d-NLR index was effective in those who developed progression in a short time. We found that the PNI was effective in patients who responded well to ICI treatment.

Purpose: The activity of osimertinib is not fully characterized in non-small-cell lung cancer (NSCLC) with uncommon epidermal growth factor receptor ( EGFR ) mutations. Therefore, we conducted a systematic review and meta-analysis to assess the safety and efficacy of osimertinib in patients with NSCLC harboring uncommon somatic EGFR mutations., Methods: PubMed, Embase, and the Cochrane Library were searched for eligible studies reporting the efficacy and safety of osimertinib in NSCLC with uncommon EGFR mutations defined as any mutations other than exon 19 deletion, L858R and T790M mutations, and exon 20 insertion, except when in compound. Then, we performed a meta-analysis to pool survival outcomes and antitumoral activity, including intracranial (ic) response and adverse events., Results: Fifteen studies comprising 594 patients were included. The most frequently observed uncommon solitary mutations were G719X in 25% (81/327) of patients and L861Q in 21% (69/327). The most common compound mutations were G719X with T790M in 12% (23/192) of patients and G719X with S768I in 11% (22/192). Pooled analysis showed an objective response rate (ORR) of 51.30% (95% CI, 45.80 to 56.81), a disease control rate (DCR) of 90.11% (95% CI, 86.27 to 92.96), a median progression-free survival of 9.71 months (95% CI, 7.96 to 11.86), and a median overall survival of 16.79 months (95% CI, 9.93 to 28.39). icORR was 45.96% (95% CI, 30.18 to 62.17), and icDCR was 95.76% (95% CI, 69.84 to 100). Osimertinib was well tolerated with a frequency of grade 3 or more adverse events of 21.77% (95% CI, 6.24 to 43.33)., Conclusion: Osimertinib demonstrated robust response in NSCLC harboring uncommon EGFR mutations, without unanticipated safety concerns.

Background: Radiotherapy plays a fundamental role in the treatment of patients with all stages of non-small-cell lung cancer (NSCLC). The emergence of immune checkpoint inhibitors (ICIs) has transformed the standard of care in these patients. The use of ICIs is increasingly utilized in the definitive setting as an adjunct to chemoradiotherapy or surgery and remains a vital component in the treatment of metastatic disease. Despite improvements in patient survival, the use of immunotherapy as monotherapy has shown limited overall response rates with susceptibility to resistance. Radiotherapy has been identified as a viable option to enhance the response rate to ICI and improve outcomes in NSCLC., Methods: We queried the English PubMed database utilizing variably combined search items including "radiation," "chemoradiation," "immune checkpoint," "immunotherapy," "stereotactic body radiotherapy," and "non-small-cell lung". We additionally searched various acceptable alternative terms for similar keywords such as "radiotherapy" in place of "radiation." These results were subsequently curated for relevance and impact on current treatment paradigms., Results: In this review, we discuss preclinical and clinical studies relating to combinatorial use of immunotherapy and radiation in NSCLC. These studies are presented in the context of early-stage, operable stage III, unresectable stage III, and metastatic disease. The majority of the data illustrate promising results regarding the additive or synergistic effects of radiation and immunotherapy with a suggestion that the timing of these treatment modalities is crucial to optimizing outcomes., Conclusion: While there is now evidence regarding the favorable interplay between radiation and immunotherapy in NSCLC, there remain multiple unanswered questions which are expected to be addressed in ongoing clinical trials., (© 2024 The Author(s).

Malignant mesothelioma is a rare highly invasive tumour originating from the mesothelial cells of the pleura, peritoneum and pericardium. Malignant pleural mesothelioma (MPM) is the most common type in all malignant mesothelioma. The onset of MPM is associated with exposure to asbestos and it can have an incubation period of up to 40 years. The incidence of MPM has been increasing worldwide in recent years, so more attention has been focused on its diagnosis, treatment and prognosis. Activating mutations, amplifications and fusions/rearrangements of the anaplastic lymphoma kinase receptor tyrosine kinase ( ALK ) gene are commonly seen in patients with non-small cell lung cancer. However, it is rare in MPM. This current case report describes a female patient with advanced MPM with an ALK gene fusion mutation. In this particular case, treatment with crizotinib demonstrated some initial efficacy, which suggests that this might be a promising strategy for patients with advanced MPM with an ALK gene mutation. This required further research and evaluation in the future., Competing Interests: Declaration of conflicting interestThe authors declare that there are no conflicts of interest.

Background: Correctly distinguishing between benign and malignant pulmonary nodules can avoid unnecessary invasive procedures. This study aimed to construct a deep learning radiomics clinical nomogram (DLRCN) for predicting malignancy of pulmonary nodules., Methods: One thousand and ninety-eight patients with 6-30 mm pulmonary nodules who received histopathologic diagnosis at 3 centers were included and divided into a primary cohort (PC), an internal test cohort (I-T), and two external test cohorts (E-T1, E-T2). The DLRCN was built by integrating adipose tissue radiomics features, intranodular and perinodular deep learning features, and clinical characteristics for diagnosing malignancy of pulmonary nodules. The least absolute shrinkage and selection operator (LASSO) was used for feature selection. The performance of DLRCN was assessed with respect to its calibration curve, area under the curve (AUC), and decision curve analysis (DCA). Furthermore, we compared it with three radiologists. The net reclassification improvement (NRI), integrated discrimination improvement (IDI), and subgroup analysis were also taken into account., Results: The incorporation of adipose tissue radiomics features led to significant NRI and IDI (NRI = 1.028, p < 0.05, IDI = 0.137, p < 0.05). In the I-T, E-T1, and E-T2, the AUCs of DLRCN were 0.946 (95% CI: 0.936, 0.955), 0.948 (95% CI: 0.933, 0.963) and 0.962 (95% CI: 0.945, 0.979), The calibration curve revealed good predictive accuracy between the actual probability and predicted probability (p > 0.05). DCA showed that the DLRCN was clinically useful. Under equal specificity, the sensitivity of DLRCN increased by 8.6% compared to radiologist assessments. The subgroup analysis conducted on adipose tissue radiomics features further demonstrated their supplementary value in determining the malignancy of pulmonary nodules., Conclusion: The DLRCN demonstrated good performance in predicting the malignancy of pulmonary nodules, which was comparable to radiologist assessments. The adipose tissue radiomics features have notably enhanced the performance of DLRCN., (© 2024 The Author(s). Cancer Medicine published by John Wiley & Sons Ltd.)

Background/aim: Non-small-cell lung cancer (NSCLC) comprises approximately 85% of lung cancer. Treatment with docetaxel prolongs the survival of patients with NSCLC. However, the development of resistance to docetaxel has compromised its efficacy. Caffeic acid phenethyl ester (CAPE) has been reported to suppress survival and radiotherapy resistance in lung cancer cells. We determined in this study if combination treatment of docetaxel with CAPE suppresses the proliferation and the survival of NSCLC cells more effectively., Materials and Methods: Proliferation, viability, flow cytometric and comet assays were used to examine the difference in anticancer effects of combined treatment as compared to docetaxel treatment alone. Western blot and gene overexpression were used to unravel the underlying molecular mechanism., Results: Treatment with docetaxel or CAPE alone dose-dependently suppressed the proliferation and survival of H1299 and A549 cells. Combined treatment of docetaxel with CAPE caused greater inhibition of survival of H1299 and A549 cells. Docetaxel alone and the combined treatment both dose-dependently increased apoptosis of H1299 cells; however, combined treatment induced much more apoptosis than docetaxel alone. Combined treatment suppressed the protein expression of phospho-protein kinase B (AKT, Ser 473), S-phase protein 2 (SKP2), MYC proto-oncogene bHLH transcription factor (c-MYC), epidermal growth factor receptor (EGFR), phospho-EGFR (Tyr 1045, and Tyr 992) but increased levels of cleaved caspase 3 and cytochrome c proteins in H1299 and A549 cells. The inhibition of expression of SKP2, c-MYC, phospho-EGFR (Tyr 992) proteins by combined treatment was significantly greater than that with treatment using either CAPE or docetaxel alone. Overexpression of c-MYC in rescued proliferation of H1299 cells under combination treatment., Conclusion: Our study revealed that the combination of CAPE with docetaxel is more effective at reducing the proliferation and survival of NSCLC cells, and this is via inhibition of c-MYC. Combined therapy of docetaxel and CAPE may benefit patients with NSCLC., (Copyright © 2024 International Institute of Anticancer Research (Dr. George J. Delinasios), All rights reserved.)

Background/purpose: Effective prevention could protect the health of the workforce, save human capital loss, and maintain employee productivity as well as economic growth., Methods: Using real-world data of patients with end-stage kidney disease (ESKD) and lung cancer, we multiplied their lifetime survival functions with employment ratios and working salaries to estimate the lifetime employment durations and earnings. They were compared with corresponding age-, sex-, and calendar year-matched referents to assess the differences in loss of lifetime employment duration and earnings. From 2000 to 2017, 83,358 patients with end-stage kidney disease (ESKD) were associated with 32-66% lifetime productivity losses. Similarly, we collected 24,904 incident cases of lung adenocarcinoma during 2011-2018 and estimated the potential savings in human capital due to early detection. Based on the evolving trends of ESKD incidence rates in Taiwan, we calculated the lifetime human capital losses of ESKD patients in GDP (gross domestic product) percentages during 2000-2020., Results: The aggregate lifetime productivity losses of ESKD in terms of GDP% varied between 0.000398% and 0.01% for male patients and between 0.0001% and 0.009% for female patients. The younger the patients, the bigger the losses in GDP%. Similarly, early detection of lung adenocarcinoma saved lives and productivity to some extent., Conclusions: Successful prevention of catastrophic illnesses at early stages would save the lifetime employment duration and productivity of the workforce. Future reform on the NHI could consider closer coordination between public health and healthcare organizations, focusing on effective prevention of diseases and complications to save productivity loss., Competing Interests: Declaration of competing interest The authors have declared that no competing interests exist.

Introduction: HER2 mutations are reported to occur in 2%-5% of all cases of non-small cell lung cancer (NSCLC). The clinical outcomes in patients with HER2-mutant NSCLC treated with immune checkpoint inhibitors (ICIs) plus platinum-based chemotherapy as 1st line treatment still remain unclear., Methods: Using the large-scale clinico-genomic database of LC-SCRUM-Asia, the clinico-genomic characteristics and therapeutic outcomes of patients with HER2-mutant NSCLC were investigated., Results: Of the 15,251 patients with NSCLC enrolled in the LC-SCRUM-Asia database, tumor HER2 mutations were detected in 402 patients (2.6 %). The most common subtype of HER2 mutations was exon 20 in-frame insertions (79 %), followed in frequency by mutations in the tyrosine kinase domain other than Exon20ins (10 %) and mutations in extracellular domains (7 %). NSCLCs harboring HER2 mutations showed a higher tumor mutation burden (TMB) as compared with NSCLCs harboring EGFR mutations or ALK fusions (median: 4.22 vs. 2.54 and 2.52 mutation per megabase, respectively). Of the 402 patients, 268 patients had received platinum-based chemotherapy with ICIs (Chemo-ICI, n = 95) or without ICI (Chemo-alone, n = 173) as 1st line treatment. The progression-free survival (PFS) was significantly longer in the Chemo-ICI group as compared with the Chemo-alone group (median 8.5 vs. 6.3 months; HR [95 %CI]: 0.66 [0.50-0.88]; P < 0.005). Multivariate analysis identified use of ICIs in addition to platinum-based chemotherapy as an independent favorable prognostic factor for PFS. There was no significant difference in the overall survival between the patients of the Chemo-ICI and Chemo-alone groups (median 31.1 vs. 23.3 months; HR [95 %CI]: 0.80 [0.57-1.12], P = 0.20)., Conclusions: Addition of ICIs to platinum-based chemotherapy in 1st line treatment may improve the PFS in patients with HER2-mutant NSCLC. The relatively high TMB might be involved in the prolongation of the PFS in patients with HER2-mutant NSCLC receiving platinum-based chemotherapy with ICIs., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Hibiki Udagawa reports grants from Takeda Pharmaceutical Co., Ltd., Nippon Boehringer Ingelheim Co., Ltd., Amgen K.K., Taiho Pharmaceutical Co., Ltd.

Introduction: Many clinical studies showed a synergy of epidermal growth factor receptor (EGFR)-tyrosine kinase inhibitors (TKIs) and vascular endothelial growth factor inhibitors. We hypothesized afatinib plus bevacizumab exerts clinical potency after developing various osimertinib resistant mechanisms., Methods: EGFR-mutant non-small cell lung cancer patients were enrolled after osimertinib resistance. Afatinib at 30-40 mg/day and bevacizumab at 15 mg/kg tri-weekly were administered until progression. Plasma/histologic rebiopsied samples after osimertinib failure were analyzed to examine resistant mechanisms: gene alterations/copy-number gain using cancer personalized profiling by deep sequencing., Results: Between January 2018 and October 2020, 28 patients were enrolled. Response and disease control rates were 17.9 % and 78.6 %, respectively. Median duration of response was 9.0 (range, 4.2-22.3) months. Median progression-free and overall survivals were 2.7 and 9.3 months, respectively. Twenty-eight (100 %) plasma and/or 21 (75 %) histologic rebiopsies identified: 17 (61 %) TP53; 15 (54 %) T790M; 9 (32 %) uncommon EGFR; 9 (32 %) MET; 6 (21 %) C797S; 3 (11 %) BRAF; 2 (7 %) HER2; 2 (7 %) KRAS; and 2 (7 %) PI3K mutations. One (17 %) of 6 C797S patients showed complete response. Three (33 %) of 9 uncommon EGFR-mutated patients achieved radiographic response. Neither 15 T790M-positive nor 6 EGFR downstream signaling mutations: BRAF; KRAS; or PI3K-positive patients responded, but 5 (38 %) of 13 T790M-negative patients responded. Adverse events ≥ grade 3 and incidence ≥ 5 % were: hypertension (29 %); proteinuria (7 %); and diarrhea (7 %). There were neither treatment-related death nor interstitial lung disease., Conclusions: Selected population could obtain clinical benefit from afatinib plus bevacizumab, based on rebiopsy results after osimertinib resistance., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Akito Hata: grants from MSD, Eli Lilly, Chugai, Taiho, Boehringer Ingelheim, AstraZeneca, AbbVie, and personal fees from AstraZenaca, Eli Lilly, MSD, Chugai, Pfizer, Boehringer Ingelheim, Taiho.

Purpose: Real-world, large-scale studies on the association between immune-related adverse events (irAE) and immune checkpoint inhibitor therapy effectiveness are limited. We evaluated overall survival (OS) and progression-free survival based on the occurrence and grade of irAEs., Patients and Methods: We used data from Japanese patients with unresectable advanced or recurrent non-small cell lung cancer (NSCLC) who received atezolizumab and were enrolled in J-TAIL, a multicenter, prospective, single-arm observational study., Results: Among the 1,002 patients, 190 (19.0%) developed irAEs. The most common irAEs were skin disorders (3.8%) of any grade and interstitial lung disease (1.5%) of grade ≥3. Patients who developed irAEs within 4 or 6 weeks of treatment initiation had higher baseline C-reactive protein levels than those without irAEs. OS was longer in patients with irAEs [HR, 0.66; 95% confidence interval (CI), 0.54-0.82], particularly in those with low-grade irAEs (HR, 0.45; 95% CI, 0.33-0.62), than in patients without irAEs. The HR (95% CI) for OS in patients with low-grade and high-grade skin or endocrine disorder-related irAEs was 0.42 (0.28-0.64) and 0.37 (0.15-0.88), respectively. The HR (95% CI) for OS in patients with low-grade and high-grade irAEs other than skin or endocrine disorders was 0.44 (0.30-0.65) and 1.27 (0.96-1.69), respectively., Conclusions: In patients with unresectable advanced or recurrent NSCLC treated with atezolizumab in real-world settings, irAEs are associated with a clinical benefit except in those with high-grade irAEs other than skin and endocrine disorders., Significance: Immune checkpoint inhibitors are useful for treating NSCLC but can cause life-threatening irAEs. This study had a large sample size and stratified the analysis by irAE type and grade. The results suggest that improved management of irAEs may improve the therapeutic effect of atezolizumab., (©2024 The Authors; Published by the American Association for Cancer Research.)

Although immune checkpoint inhibitor-based therapy has shown promising results in non-small cell lung cancer patients with high programmed death-ligand 1 expression, not all patients respond to therapy. The tumor microenvironment (TME) is complex and heterogeneous, making it challenging to understand the key agents and features that influence response to therapies. In this study, we leverage multiplex fluorescent immunohistochemistry to quantitatively assess interactions between tumor and immune cells in an effort to identify patterns occurring at multiple spatial levels of the TME. To do so, we introduce several computational methods novel to a data set of 1,269 multiplex fluorescent immunohistochemistry images from a cohort of 52 patients with metastatic non-small cell lung cancer. With the spatial G-cross function, we quantify the degree of cell interaction at an entire image level, where we see significantly increased activity of cytotoxic T cells and helper T cells with epithelial tumor cells in responders to immune checkpoint inhibitor-based (P = .022 and P < .001, respectively) and decreased activity of T-regulatory cells with epithelial tumor cells compared with nonresponders (P = .010). By leveraging spatial overlap methods, we define tumor subregions (which we call the tumor "periphery," "edge." and "center") and discover more localized immune-immune interactions influencing positive response, including those between cytotoxic T cells and helper T cells with antigen presenting cells in these subregions specifically. Finally, we trained an interpretable deep learning model that identified key cellular regions of interest that most influenced response classification (area under the curve = 0.71 ± 0.02). Assessing spatial interactions within these subregions further revealed new insights that were not significant at the whole image level, particularly the elevated association of antigen presenting cells and T-regulatory cells with one another in responder groups (P = .024). Altogether, we demonstrate that elucidating patterns of cell composition and interplay across multiple levels of spatial analyses can improve our understanding of the TME and better differentiate patient responses to immunotherapy., (Copyright © 2024 The Authors.

Background: The clinical outcomes of patients with anaplastic lymphoma kinase-positive (ALK+) advanced lung adenocarcinoma vary according to real-world data., Objective: In this study, we aimed to investigate the treatment discontinuation (TTD) and overall survival (OS) of patients with ALK+ advanced lung adenocarcinoma treated with first-line ALK-TKIs in Taiwan., Patients and Methods: This retrospective study evaluated all advanced lung adenocarcinoma patients registered in the National Taiwan Cancer Registry from 2017 to 2020 who had ALK rearrangement and received ALK-TKI treatment, using data from Taiwan's National Health Insurance Research Database (NHIRD). The TKI treatment sequences were classified into first generation (G1: crizotinib), second generation (G2: ceritinib, alectinib, brigatinib), and third generation (G3: lorlatinib)., Results: A total of 587 patients were analyzed, with a median age of 60.0 years, 91 (15.5%) aged ≥ 74 years, 293 (49.9%) female, 397 (67.6%) never smoked, and 534 (91.0%) with stage IV disease. Patients who received next-generation ALK-TKIs during the treatment course had longer median time to ALK-TKI TTD and OS. The TTD of the G1, G1+2, G1+2+3, G2, and G2+3 groups was 7.5 (5.4-11.1), 40.6 (29.4-not calculated (NC)), 50.3 (41.3-NC), 34.3 (29.2-43.0), and 36.3 (22.4-NC) months, respectively (p < 0.001). The median OS of the patients in the G1, G1+2, G1+2+3, G2, and G2+3 groups was 10.6 (7.5-14.6), not reached (NR) (NC-NC), NR (NC-NC), 43.0 (36.3-NC), and NR (30.3-NC) months, respectively (p < 0.001). Compared with treatment with crizotinib alone, the multivariate analysis revealed that treatment with next-generation TKIs was independently associated with longer TTD (G1+2 (hazard ratio (HR), 0.24; 95% CI 0.17-0.33; p < 0.001), G1+2+3 or G1+3 (HR, 0.17; 95% confidence interval (CI), 0.10-0.28; p < 0.001), G2 (HR, 0.26; 95% CI 0.19-0.36; p < 0.001), and G2+3 (HR, 0.25; 95% CI 0.14-0.44; p < 0.001)) and median OS (G12 (HR, 0.24; 95% CI 0.17-0.35; p < 0.001), G1+2+3 or G1+3 (HR, 0.09; 95% CI 0.04-0.21; p < 0.001), G2 (HR, 0.22; 95% CI 0.15-0.31; p < 0.001), and G2+3 (HR, 0.20; 95% CI 0.10-0.42; p < 0.001))., Conclusions: For patients with ALK+ NSCLC, treatments including next-generation ALK-TKIs were independently associated with longer survival outcomes., Competing Interests: Declarations Funding This study was funded by Pfizer (tracking no. 75046155), the Ministry of Health and Welfare (MOHW112-TDU-B-222-124019), and Formatting the Risk Prediction Models for Never-Smoking Lung Cancer (FORMOSA).

For patients with advanced non-small-cell lung cancer (NSCLC), dual immune checkpoint blockade (ICB) with CTLA4 inhibitors and PD-1 or PD-L1 inhibitors (hereafter, PD-(L)1 inhibitors) is associated with higher rates of anti-tumour activity and immune-related toxicities, when compared with treatment with PD-(L)1 inhibitors alone. However, there are currently no validated biomarkers to identify which patients will benefit from dual ICB 1,2 . Here we show that patients with NSCLC who have mutations in the STK11 and/or KEAP1 tumour suppressor genes derived clinical benefit from dual ICB with the PD-L1 inhibitor durvalumab and the CTLA4 inhibitor tremelimumab, but not from durvalumab alone, when added to chemotherapy in the randomized phase III POSEIDON trial 3 . Unbiased genetic screens identified loss of both of these tumour suppressor genes as independent drivers of resistance to PD-(L)1 inhibition, and showed that loss of Keap1 was the strongest genomic predictor of dual ICB efficacy-a finding that was confirmed in several mouse models of Kras-driven NSCLC. In both mouse models and patients, KEAP1 and STK11 alterations were associated with an adverse tumour microenvironment, which was characterized by a preponderance of suppressive myeloid cells and the depletion of CD8 + cytotoxic T cells, but relative sparing of CD4 + effector subsets. Dual ICB potently engaged CD4 + effector cells and reprogrammed the tumour myeloid cell compartment towards inducible nitric oxide synthase (iNOS)-expressing tumoricidal phenotypes that-together with CD4 + and CD8 + T cells-contributed to anti-tumour efficacy. These data support the use of chemo-immunotherapy with dual ICB to mitigate resistance to PD-(L)1 inhibition in patients with NSCLC who have STK11 and/or KEAP1 alterations., Competing Interests: Competing interests F.S. reports consulting for AstraZeneca, Amgen, Revolution Medicines, Novartis, BridgeBio, Beigene, BergenBio, Guardant Health, Calithera Biosciences, Tango Therapeutics, Hookipa Pharma, Novocure, Merck Sharp & Dohme, Roche; grant or research support from Amgen, Mirati Therapeutics, Revolution Medicines, Pfizer, Novartis, Merck & Co; stockholder in BioNTech, Moderna; and honoraria from ESMO, Japanese Lung Cancer Society, Medscape, Intellisphere, VSPO McGill Universite de Montreal, RV Mais Promocao Eventos, MJH Life Sciences, IDEOlogy Health, MI&T, PER, CURIO, DAVA Oncology, the American Association for Cancer Research and the International Association for the Study of Lung Cancer.

According to the 2022 cancer statistics of the World Health Organization, lung cancer ranks among the top ten causes of death, with lung adenocarcinoma being the most prevalent type. Despite significant advancements in lung cancer therapeutics, many clinical limitations remain, primarily due to the development of drug resistance. The present study investigated the effects of pemetrexed on the drug resistance mechanisms in human lung adenocarcinoma and its association with progesterone receptor membrane component 1 (PGRMC1) expression. Given that KRAS-mutant lung adenocarcinoma cell lines (e.g., A549) exhibit a high folate synthesis activity, pemetrexed, which is structurally similar to folate, was selected as the therapeutic drug. The present study used a lung adenocarcinoma cell line (A549) and established a drug-resistant lung adenocarcinoma cell line (A549/PEM). The findings demonstrated that PGRMC1 expression was elevated in the A549/PEM cells. It has been hypothesized that PGRMC1 regulates iron absorption through heme binding, resulting in a preference for iron-related cell death pathways (ferroptosis). Our findings indicate that drug-resistant lung adenocarcinoma cells with high PGRMC1 levels exhibit elevated antioxidant activity on the cell membrane and increased reliance on iron-dependent cell death pathways. This suggests a correlation between PGRMC1 and pemetrexed-induced iron-dependent cell death. Our study contributes to the development of more effective therapeutic strategies to improve the prognosis of patients with lung adenocarcinoma, particularly those facing drug resistance challenges., Competing Interests: Declaration of competing interest The authors declare that they have no conflict of interests., (Copyright © 2024 Elsevier B.V.

Background: There is a dearth of studies on the efficacy and safety of the tyrosine kinase inhibitors osimertinib (OSI) and gefitinib (GEF) in treating epidermal growth factor receptor (EGFR) mutation-positive non-small cell lung cancer (NSCLC), even in patients with poor performance status (PS)., Methods: We retrospectively reviewed and compared data of 113 patients with EGFR mutation-positive NSCLC with Eastern Cooperative Oncology Group PS 2-4 who were administered OSI 80 mg/day or GEF 250 mg/day from May 2016 to March 2022., Results: The GEF group (39 patients; median age: 74 years) included 20 patients with a PS of 2, 17 with a PS of 3, and 2 with a PS of 4. The OSI group (74 patients; median age: 76 years) included 48 patients with a PS of 2, 24 with a PS of 3, and 2 with a PS of 4. The overall response rates were 69% and 66% in the GEF and OSI groups, respectively. The disease control and PS improvement rates were 89% and 51% in both groups, respectively. The median progression-free survival in the GEF and OSI groups was 6.9 and 9.2 months, respectively (p = 0.15). The OSI group experienced better overall survival than the GEF group (median: 20.9 vs. 13.0 months, p = 0.0031). The incidence of pneumonitis was 10% and 11% in the GEF and OSI groups, respectively. One treatment-related death owing to pneumonitis occurred in the GEF group., Conclusions: OSI may be a useful treatment for untreated EGFR mutation-positive NSCLC with poor PS., Competing Interests: Declaration of competing interest Kazuhisa Nakashima has received personal fees from Taiho Pharmaceutical, Chugai Pharma, AstraZeneca, Eli Lilly Japan, Nippon Kayaku, and Bristol-Myers Squibb.

EGFR mutations are a major prognostic factor in lung adenocarcinoma. However, current detection methods require sufficient samples and are costly. Deep learning is promising for mutation prediction in histopathological image analysis but has limitations in that it does not sufficiently reflect tumor heterogeneity and lacks interpretability. In this study, we developed a deep learning model to predict the presence of EGFR mutations by analyzing histopathological patterns in whole slide images (WSIs). We also introduced the EGFR mutation prevalence (EMP) score, which quantifies EGFR prevalence in WSIs based on patch-level predictions, and evaluated its interpretability and utility. Our model estimates the probability of EGFR prevalence in each patch by partitioning the WSI based on multiple-instance learning and predicts the presence of EGFR mutations at the slide level. We utilized a patch-masking scheduler training strategy to enable the model to learn various histopathological patterns of EGFR. This study included 868 WSI samples from lung adenocarcinoma patients collected from three medical institutions: Hallym University Medical Center, Inha University Hospital, and Chungnam National University Hospital. For the test dataset, 197 WSIs were collected from Ajou University Medical Center to evaluate the presence of EGFR mutations. Our model demonstrated prediction performance with an area under the receiver operating characteristic curve of 0.7680 (0.7607-0.7720) and an area under the precision-recall curve of 0.8391 (0.8326-0.8430). The EMP score showed Spearman correlation coefficients of 0.4705 (p = 0.0087) for p.L858R and 0.5918 (p = 0.0037) for exon 19 deletions in 64 samples subjected to next-generation sequencing analysis. Additionally, high EMP scores were associated with papillary and acinar patterns (p = 0.0038 and p = 0.0255, respectively), whereas low EMP scores were associated with solid patterns (p = 0.0001). These results validate the reliability of our model and suggest that it can provide crucial information for rapid screening and treatment plans., (© 2024 The Author(s).

Background: The effect of dual immunotherapy combined with platinum-based chemotherapy on untreated brain metastases derived from non-small cell lung cancer (NSCLC) has remained unclear., Methods: This multicenter single-arm phase 2 study enrolled patients with chemotherapy-naïve advanced NSCLC and at least one brain metastasis ≥ 5 mm in size that had not been previously treated. Patients received nivolumab plus ipilimumab combined with platinum-doublet chemotherapy (two cycles), followed by nivolumab-ipilimumab alone. The primary endpoint of the study was intracranial response rate as determined by modified Response Evaluation Criteria in Solid Tumors (RECIST) for brain metastases of ≥ 5 mm as target lesions., Results: A total of 30 patients from 18 institutions was enrolled in this study. The median age was 66.5 years (range, 47-83 years), and 26 patients (87 %) had a non-squamous cell carcinoma histology. The median size of all target brain lesions was 8.4 mm, with a range of 5-39 mm. The intracranial response rate assessed by modified RECIST was 50.0 % (95 % CI, 33.2-66.8 %), with the rate of complete response being 20.0 %, and the study met its primary endpoint. The systemic response rate was 53.3 % (95 % CI, 36.1-69.8 %), and responses for intracranial and extracranial lesions were generally consistent. The median intracranial progression-free survival was 8.1 months, and both the median intracranial duration of response and time to brain radiotherapy were not reached., Conclusion: Nivolumab plus ipilimumab combined with platinum-based chemotherapy showed promising intracranial activity in NSCLC patients with untreated brain metastases., Trial Registration: jRCT071210019., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Y Tsuchiya-Kawano has received personal fees from Bristol-Myers Squibb, Taiho Pharmaceutical, Chugai Pharmaceutical, AstraZeneca, Kyowa hakko Kirin, MSD, Ono Pharmaceutical, and Takeda Pharmaceutical outside the submitted work.

Neoantigen immunoediting drives immune checkpoint blockade efficacy, yet the molecular features of neoantigens and how neoantigen immunogenicity shapes treatment response remain poorly understood. To address these questions, 80 patients with non-small cell lung cancer were enrolled in the biomarker cohort of CheckMate 153 (CA209-153), which collected radiographic guided biopsy samples before treatment and during treatment with nivolumab. Early loss of mutations and neoantigens during therapy are both associated with clinical benefit. We examined 1,453 candidate neoantigens, including many of which that had reduced cancer cell fraction after treatment with nivolumab, and identified 196 neopeptides that were recognized by T cells. Mapping these neoantigens to clonal dynamics, evolutionary trajectories and clinical response revealed a strong selection against immunogenic neoantigen-harboring clones. We identified position-specific amino acid and physiochemical features related to immunogenicity and developed an immunogenicity score. Nivolumab-induced microenvironmental evolution in non-small cell lung cancer shared some similarities with melanoma, yet critical differences were apparent. This study provides unprecedented molecular portraits of neoantigen landscapes underlying nivolumab's mechanism of action., Competing Interests: Competing interests T.A.C. is a cofounder of and holds equity in Gritstone Oncology.

Introduction: Among older adults without cancer, living alone is associated with poor health outcomes. However, among older adults with non-small cell lung cancer (NSCLC) who live alone, data on function, cognition, and quality of life (QOL) during systemic treatment remain limited., Materials and Methods: We enrolled adults aged ≥65 with advanced NSCLC starting a new chemotherapy, immunotherapy, and/or targeted therapy regimen with non-curative intent. Patients completed geriatric assessments including instrumental activities of daily living (IADL), Montreal Cognitive Assessment, and QOL pretreatment and at 1, 2, 4, and 6 months, or until treatment discontinuation, whichever occurred earlier. We categorized change in IADL, cognition, and QOL as stable/improved, declined with recovery, or declined without recovery using clinically meaningful definitions of change. We used multinomial logistic regression to compare change between patients who lived alone versus with others., Results: Among 149 patients, median age was 73; 21% lived alone. Pretreatment IADL, cognition, and QOL scores were similar between older adults who lived alone versus with others. During NSCLC treatment, older adults who lived alone had similar trajectories of function (52% functional decline vs 38%), cognition (43% cognitive decline vs 50%), and QOL (45% QOL decline vs 44%) compared with those who lived with others. In unadjusted analyses, patients who lived alone were more likely to develop functional decline with recovery (reference category: stable/improved function) than those who lived with others (relative risk ratio 4.07, 95% CI 1.14-14.6, p = 0.03). However, this association was not observed after adjusting for age, race, prior NSCLC treatment, current treatment group, and pretreatment geriatric assessment differences. There were no differences in cognitive or QOL trajectories in unadjusted or adjusted analyses., Discussion: Approximately half of older adults with advanced NSCLC who lived alone were able to maintain their function, cognition, and QOL during NSCLC treatment, which was similar to older adults who lived with others. Many older adults with advanced NSCLC who live alone can receive systemic treatment with individualized supportive care., Competing Interests: Declaration of Competing Interest SS reported conflicts of interest outside the submitted work (consultant/advisory to Oncohost).

Locoregional recurrence of non-small-cell lung cancer (NSCLC) after complete resection lacks standard treatment. Durvalumab after chemoradiotherapy (CRT) or CRT alone is often selected in daily clinical practice for patients with locoregional recurrence; however, the therapeutic efficacy of these treatments remains unclear, and we aimed to assess this. This retrospective observational study used data from patients with NSCLC diagnosed with locoregional recurrence after complete resection who subsequently underwent concurrent CRT followed by durvalumab (CRT-D group) or CRT alone (CRT group). We employed propensity score analysis with inverse probability treatment weighting (IPTW) to adjust for various confounders and evaluate efficacy in the CRT-D group. After IPTW adjustment, the CRT-D group contained 119 patients (64.7% male; 69.7% adenocarcinoma), and the CRT group contained 111 patients (60.5% male; 73.4% adenocarcinoma). Their mean ages were 66 and 65 years, respectively. The IPTW-adjusted median progression-free survival was 25.4 and 11.5 months for the CRT-D and CRT groups, respectively (hazard ratio, 0.44; 95% confidence interval, 0.30-0.64); the median overall survival was not reached in either group favoring CRT-D (hazard ratio, 0.49; 95% confidence interval, 0.24-0.99). Grade 3 or 4 adverse events were observed in 48.8% of patients during CRT, 10.7% after initiating durvalumab maintenance therapy in the CRT-D group, and 57.3% in the CRT group. Overall, the sequential approach of CRT followed by durvalumab is a promising treatment strategy for locoregional recurrence of NSCLC after complete resection., (© 2024 The Author(s).

Introduction: Lung cancer survival is significantly improved with early detection. However, lung cancer screening (LCS) uptake remains low despite national recommendations. Our aim was to determine whether implementation of an electronic medical record (EMR) alert and order set would increase LCS uptake., Study Design: A query of current and former smokers identified 62,630 patients aged 50 and above in the primary care setting between January 1, 2021 and May 5, 2022. We randomly reviewed 3704 charts for LCS eligibility and recorded who received LCS in the form of low-dose computed tomography amongst the eligible patients. We collected demographic information including gender, race, primary language, ethnicity, zip code, and insurance. Data analysis was performed utilizing 2-proportional z tests., Results: We identified 461 patients who were LCS eligible. Our overall LCS uptake was 19.9% (92/461). Three-time frames were analyzed: (1) prior to EMR alert implementation, (2) after implementation of EMR alert (January 7, 2021), and (3) after implementation of EMR alert and order set (March 3, 2021). Screening uptake was significantly improved with initiation of EMR alert (1/46 [2.2%] to 23/109 [21.1%]; P = .003). LCS uptake remained similarly high after subsequent order set implementation (23/109 [21.1%] and 68/306 [22.2%]; P = .72). Amongst the different demographics, age was significantly associated with screening uptake, with age ≥65 demonstrating statistically significant increased rates of screening (15.6% [41/263] for <65 vs 25.8% [51/198] for ≥65; P = .007)., Conclusion: Implementation of EMR alerts significantly improves LCS uptake in the primary care setting. Such efforts should be considered in other hospital settings to improve LCS uptake., Competing Interests: Disclosure The authors have stated that they have no conflicts of interest., (Copyright © 2024 Elsevier Inc.

Immunotherapy targeting immune checkpoints (ICPs), such as programmed death-ligand-1 (PD-L1), is used as a treatment option for advanced or metastatic non-small cell lung cancer (NSCLC). However, overall response rate to anti-PD-L1 treatment is limited due to antigen heterogeneity and the immune-suppressive tumor microenvironment. Human leukocyte antigen-G (HLA-G), an ICP as well as a neoexpressed tumor-associated antigen, is previously demonstrated to be a beneficial target in combination with anti-PD-L1. In this study, a nanobody-based trispecific T cell engager (Nb-TriTE) is developed, capable of simultaneously binding to T cells, macrophages, and cancer cells while redirecting T cells toward tumor cells expressing PD-L1- and/or HLA-G. Nb-TriTE shows broad spectrum anti-tumor effects in vitro by augmenting cytotoxicity mediated by human peripheral blood mononuclear cells (PBMCs). In a humanized immunodeficient murine NSCLC model, Nb-TriTE exhibits superior anti-cancer potency compared to monoclonal antibodies and bispecific T cell engagers. Nb-TriTE, at the dose with pharmacoactivity, does not induce additional enhancement of circulating cytokines secretion from PMBCs. Nb-TriTE effectively prolongs the survival of mice without obvious adverse events. In conclusion, this study introduces an innovative therapeutic approach to address the challenges of immunotherapy and the tumor microenvironment in NSCLC through utilizing the dual ICP-targeting Nb-TriTE., (© 2024 The Author(s).

Non-small cell lung cancer (NSCLC) patients without targetable driver mutation have limited treatment options. In this study, we aimed to explore a new therapeutic strategy by using established nine patient-derived xenograft (PDX) and two-dimensional (2D) /3D culture models with specific genetic alternations. The gene mutations and copy number aberrations were detected by next-generation sequencing and confirmed using polymerase chain reaction (PCR) followed by DNA sequencing, and genomic DNA quantitative PCR. Protein expression was evaluated by immunohistochemistry. Drug sensitivities of PDX/2D/3D models were evaluated by in vivo and in vitro antitumor assays. RNA interference was performed to silence gene expression. Our study found that 44.4 % (4/9) of cases had CDKN2A homozygous deletion (homdel), while 33.3 % (3/9) had CDKN2B homdel. Additionally, 22.2 % (2/9) had amplification (amp) in wildtype CDK4, 44.4 % (4/9) in CDK6, and 44.4 % (4/9) in EGFR. Among the cases, 77.8 % (7/9) lacked CDKN2A, and 33.3 % (3/9) had high CDK4, CDK6, and EGFR had high protein expression. Moreover, 33.3 % (3/9) had KRAS mutations, and 66.7 % (6/9) had TP53 mutations. Antitumor activity of osimertinib plus palbociclib was assessed in four PDX/2D/3D models, two of which had simultaneous EGFR amp and CDKN2A/2B homdel. The data showed that NSCLC with EGFR amp and CDKN2A/2B homdel were sensitive to combined drugs. Additional oncogenic KRAS mutation reduced the drug's antitumor effect. EGFR amp is responsible for osimertinib sensitivity. Osimertinib plus palbociclib effectively treat NSCLC with wildtype EGFR and CDK6 amp and CDKN2A/2B homdel in the absence of oncogenic KRAS mutation., Competing Interests: Declaration of competing interest The authors declare no conflict-of-interest., (Copyright © 2024.

Background: Seasonal variations in systemic immunity have been reported. This study aimed to evaluate whether seasonality affects the efficacy of anticancer immunotherapy., Methods: A total of 604 patients with lung cancer receiving single anti-programmed cell death (ligand) 1 (anti-PD-[L]1) inhibitors from two prospective observational cohorts were screened. Primary outcomes were progression-free survival (PFS) and overall survival (OS). Patients were classified into two groups according to the season when the treatment started: winter (November-February) and other seasons (March-October). Kaplan-Meier analysis and Cox proportional hazards models were fitted to evaluate the impact of seasonality on survival. For validation, propensity score matching was performed., Results: A total of 484 patients with advanced non-small cell lung cancer were included. In an unmatched population, multivariable analysis demonstrated that the winter group (n = 173) had a significantly lower risk of progression or death from immunotherapy than the other group (n = 311) (PFS: hazard ratio [HR], 0.77 [95% confidence interval (CI), 0.62-0.96]; p = .018; OS: HR, 0.77 [95% CI, 0.1-0.98]; p = .032). In a propensity score-matched population, the winter group (n = 162) showed significantly longer median PFS (2.8 months [95% CI, 1.9-4.1 months] vs. 2.0 months [95% CI, 1.4-2.7 months]; p = .009) than the other group (n = 162). The winter group's median OS was also significantly longer than that of the other group (13.4 months [95% CI, 10.2-18.0 months] vs. 8.0 months [95% CI, 3.6-8.7 months]; p = .012). The trend toward longer survival in the winter group continued in subgroup analyses., Conclusions: Starting an anti-PD-(L)1 inhibitor in winter was associated with better treatment outcomes in patients with lung cancer compared to other seasons., (© 2024 American Cancer Society.)

Background: The optimal subsequent treatment strategy for locally advanced non-small cell lung cancer (LA-NSCLC) after chemoradiotherapy (CRT) and consolidative durvalumab therapy remains unknown. We aimed to determine the optimal subsequent treatment strategy for this clinical population., Materials and Methods: We retrospectively enrolled 523 consecutive patients with LA-NSCLC treated with CRT and analyzed the treatment outcomes of subsequent therapy after progression following CRT and consolidative durvalumab therapy. Patients who received tyrosine kinase inhibitors as subsequent therapy were excluded., Results: Out of 122 patients who received subsequent chemotherapy, 55% underwent platinum-based, 25% non-platinum-based, and 20% immune checkpoint inhibitor (ICI)-containing therapies. In the platinum-based group, patients with a durvalumab-progression-free survival (Dur-PFS) ≥ 1 year had a significantly longer median subsequent therapy-PFS (SubTx-PFS) than those with Dur-PFS < 1 year (13.2 months vs. 4.7 months; hazard ratio, 0.45; 95% confidence interval, 0.21-0.97; P = .04). Furthermore, among patients receiving non-platinum-based chemotherapy, the median SubTx-PFS was longer in the combined with angiogenesis inhibitor group than in the without group, although the difference was not statistically significant. No significant difference of SubTx-PFS was observed between the reason for durvalumab discontinuation and the outcomes of ICI-containing therapy., Conclusion: In clinical practice, platinum-based chemotherapy rechallenge is frequently employed following progression subsequent to CRT and consolidative durvalumab therapy for LA-NSCLC. Optimal treatment strategies may consider Dur-PFS and angiogenesis inhibitor feasibility. Further research is warranted to identify clinical biomarkers that can help identify patients who would benefit from ICI rechallenge., Competing Interests: Disclosure Hayato Kawachi reported receiving personal fees from AstraZeneca, Bristol-Myers Squibb, Chugai Pharmaceutical, Eli Lilly, MSD, Ono Pharmaceutical, and Taiho Pharmaceutical outside the submitted work.

Aims: Despite known short-term mortality risk of immune checkpoint inhibitor (ICI) pneumonitis, its impact on 1-year mortality, long-term pulmonary function, symptom persistence, and radiological resolution remains unclear., Methods: We retrospectively analyzed 71 nonsmall cell lung cancer (NSCLC) patients treated with anti-PD(L)1 monoclonal antibodies between 2018-2021, who developed pneumonitis. Clinical and demographic covariates were collected from electronic medical record. Cox regression assessed associations with mortality, while logistic regression evaluated associations with persistent symptoms, hypoxemia, and radiological resolution., Results: Steroid-refractory pneumonitis (hazard ratio [HR] = 15.1, 95% confidence interval [95% CI]:3.9-57.8, P < .0001) was associated with higher 1-year mortality compared to steroid-responsive cases. However, steroid-resistant (odds ratio [OR] = 1.4, 95% CI: 0.4-5.1, P = .58) and steroid-dependent (OR = 0.4, 95% CI: 0.1-1.2, P = .08) pneumonitis were not. Nonadenocarcinoma histology (OR = 6.7, 95% CI: 1.6-46.6, P = .01), grade 3+ pneumonitis (OR = 4.6, 95% CI: 1.3-22.7, P = .03), and partial radiological resolution (OR = 6.3, 95% CI: 1.8-23.8, P = .004) were linked to increased pulmonary symptoms after pneumonitis resolution. Grade 3+ pneumonitis (OR = 8.1, 95% CI: 2.3-31.5, P = .001) and partial radiological resolution (OR = 5.45, 95% CI: 1.29-37.7, P = .03) associated with residual hypoxemia. Nonadenocarcinoma histology (OR = 3.6, 95% CI: 1.01-17.6, P = .06) and pretreatment ILAs (OR = 4.8, 95% CI: 1.14-33.09, P = .05) were associated with partial radiological resolution., Conclusions: Steroid refractory pneumonitis increases 1-year mortality in NSCLC patients. Pretreatment ILAs may signal predisposition to fibrosis-related outcomes, seen as partial resolution, which in turn is associated with postresolution symptoms and residual hypoxemia. These findings offer insights for identifying patients at risk of adverse outcomes post-pneumonitis resolution., (Copyright © 2024 Elsevier Inc. All rights reserved.)

Objective: This study aimed to assess the results of primary stereotactic body radiotherapy (SBRT) for spinal bone metastases (SBM) originating from lung adenocarcinoma (ADC). We considered the revised Tokuhashi score (rTS), Spinal Instability Neoplastic Score (SINS), and genetic characteristics., Methods: We examined adult patients with lung ADC who underwent primary SBRT (using the CyberKnife System) for SBM between March 2012 and January 2023., Results: We analyzed data from 99 patients, covering 152 SBM across 194 vertebrae. The overall local control (LC) rate was 77.6% for SBM from lung ADC, with a LC rate of 90.7% at 1 year. The median period for local progression (LP) occurrence was recorded at 10.0 (3-52) months. Additionally, Asian patients demonstrated higher LC rates than White patients. Utilizing the rTS and SINS as predictive tools, we revealed that a poor survival prognosis and an unstable spinal structure were associated with increased rates of LP. Furthermore, the presence of osteolytic bone destructions and pain complaints were significantly correlated with the occurrence of LP. In the cohort of this study, 108 SBM underwent analysis to determine the expression levels of programmed cell death ligand 1 (PD-L1). Additionally, within this group, 60 showed mutations in the epidermal growth factor receptor (EGFR) alongside PD-L1 expression. Nevertheless, these genetic differences did not result in statistically significant differences in the LC rate., Conclusion: The one-year LC rate for primary SBRT targeting SBM from lung ADC stood at 90.7%, particularly with the use of the CyberKnife System. Patients achieving LC exhibited significantly longer survival times compared to those with LP., Competing Interests: Disclosure The authors affirm that the content of this article was developed without any commercial or financial relationships that could be considered as potential conflicts of interest., (Copyright © 2024 Elsevier Inc.

Background: The combination of platinum-based chemotherapy and an antibody to PD-1 or to its ligand PD-L1, with or without an antibody to CTLA-4, has improved the survival of individuals with metastatic non-small-cell lung cancer (NSCLC). However, no randomised controlled trial has evaluated the survival benefit of adding a CTLA-4 inhibitor to platinum-based chemotherapy plus a PD-1 or PD-L1 inhibitor., Methods: This open-label, randomised, phase 3 trial was conducted at 48 hospitals in Japan. Eligible patients were aged 20 years or older with previously untreated advanced NSCLC and an Eastern Cooperative Oncology Group performance status of 0 or 1. Patients with known driver oncogenes were excluded. Participants were randomly assigned (1:1) to receive platinum-based chemotherapy (four cycles) plus pembrolizumab (pembrolizumab group) or platinum-based chemotherapy (two cycles) plus nivolumab-ipilimumab (nivolumab-ipilimumab group). The primary endpoint was overall survival and assessed in all randomly assigned patients on an intention-to-treat basis. The trial is registered in the Japan Registry for Clinical Trials, jRCTs031210013, and is now closed to new enrolment and is ongoing., Findings: Between patient accrual initiation on April 6, 2021, and discontinuation of the trial on March 30, 2023, 11 (7%) of 148 patients in the nivolumab-ipilimumab group had a treatment-related death. Because of the high number of treatment-related deaths, patient accrual was terminated early, resulting in 295 patients (236 [80%] male and 59 [20%] female) enrolled; the primary analysis was done on the basis of 117 deaths (fewer than the required 329 deaths). By May 25, 2023 (data cutoff), overall survival did not differ significantly between the nivolumab-ipilimumab group and the pembrolizumab group (median 23·7 months [95% CI 17·6-not estimable] vs 20·5 months [17·6-not estimable], respectively; hazard ratio 0·98 [90% CI 0·72-1·34]; p=0·46). Non-haematological adverse events of grade 3 or worse occurred in 87 (60%) of 146 patients in the nivolumab-ipilimumab group and 59 (41%) of 144 patients in the pembrolizumab group. The pembrolizumab group tended to have a better quality of life compared with the nivolumab-ipilimumab group., Interpretation: The safety and efficacy data suggest an unfavourable benefit-risk profile for nivolumab-ipilimumab combined with platinum-based chemotherapy relative to pembrolizumab combined with platinum-based chemotherapy as a first-line treatment for patients with advanced NSCLC, although a definitive conclusion awaits an updated analysis of overall survival., Funding: The National Cancer Center Research and Development Fund and Japan Agency for Medical Research and Development., Competing Interests: Declaration of interests YoS has received grants from Chugai Pharmaceutical; and personal fees from Chugai Pharmaceutical, Ono Pharmaceutical, AstraZeneca, Bristol Myers Squibb, Taiho Pharmaceutical, and Kyowa Kirin, all outside of the submitted work.

We conducted a cross-sectional, multicenter study to compare the demographics, clinical characteristics, and lung cancer screening results among individuals eligible for lung cancer screening per 2013 vs 2021 US Preventive Services Task Force recommendations. Statistical tests are 2 sided, with P less than  .05 considered statistically significant. Among 17 702 screened individuals (85.2% 2013 eligible, 14.8% 2021 newly eligible), a higher proportion of individuals screened per 2021 vs 2013 criteria were female (56.1% vs 48.1%, P < .001) and non-Hispanic Black (19.3% vs 13.4%, P < .001). The risk of developing and dying from lung cancer per 1000 people was statistically significantly higher among individuals eligible per 2013 vs 2021 criteria. A higher proportion of lung cancer screening exams had an increased suspicion of lung cancer in the 2013 vs 2021 criteria groups. Our data suggest that, as intended, updated 2021 US Preventive Services Task Force recommendations are leading to a higher proportion of lung cancer screening exams among non-Hispanic Black individuals and women., (© The Author(s) 2024.
