Adolescence is characterized by an increase in risky behaviors. The Dual Systems Models of cognitive development suggest that this could be explained by an imbalance between the development of the Socioemotional Reward System and the Cognitive Control System. Also, there is a normative increase in sexual exploration. However, some sexual behaviors are considered health risks. With a prospective longitudinal panel design, we aimed to analyze the effect of change in risk propensity, self-regulation, and consideration of future consequences (CFC) on sexual risk behaviors in adolescents aged 15-20 years from Montevideo (Uruguay). In a sample of 49 adolescents, we measure cognitive variables at T1 and T2 using behavioral tasks and scales. We surveyed sexual behaviors at T2. Congruent with Dual Systems Models, we observed a decrease in risk propensity and CFC-Immediate, and the decrease in risk propensity impact the use of contraceptive methods. No significant results found for self-regulation and CFC-Future. more...

SUMMARY The aim of this study is to present the analysis of the leading causes of mortality found in all the cases of maternal death at the Hospital de Ginecobstetricia (HGO) and Hospital de Especialidades (HE) del Centro Médico Nacional de Occidente (CMNO), during a period of 12 years, to achieve a winder view and to find a solution to reduce maternal mortality (MM). We reviewed files and reports of the maternal mortality committee of 151 women who were hospitalized and died at the HGO and HE del CMNO in Guadalajara, Jalisco, México, between January firths, 1985 and December 31, 1996. During this period the maternal death ratio was 64 per 100,000 live births. The main cause of maternal death was toxemia 25%, follow by hemorrhage 23%, pulmonary thromboembolism 16%, infection 13%, and anesthetic complications 6%. 73% were foreseen deaths and 23% were unforeseen deaths. At the patients arrival to the hospital 37% were avoidable deaths. 66% were direct obstetric deaths and 34% were avoidable deaths. 66% were direct obstetric deaths and 34% were indirects. In 50% of the cases the end of pregnancy was done by cesarean section. The professional responsability existed in the 72% and the hospitalary in the 23%. We made an analysis related factors and we propose strategies to diminish the maternal mortality. [ABSTRACT FROM AUTHOR] more...

SUMMARY The partnership the insulin-like growth factor (IGF) in women with polycystic ovary syndrome (PCOS) is characterized by mechanisms underlying alterations in the GH/IGF-1, axis. In the pathogenesis exist a sinergism markedly enhanced between IGF-1 and insulin, and IGF-1 with LH to increase androgen production, causing a reduced IGFBPs and SHBG production, the resulting hyperandrogenism, within and ouside the ovary, may inhibitor follicular maturation and the biosynthesis of estrogen. At the present, the data suggests up to date paracrine, autocrine as well as endocrine actions in the ovary in normal conditions and the lost of this homeostasis can be followed by neuro-endocrine.

SUMMARY Nitric oxide (_GCB_NO) produced by the majority of animal cells, has been considered a second messenger, since it is the result of a transduction process induced by a first stimulus. Biochemically, _GCB_NO is produced during the conversion of L-arginine to L-citruline by a reaction catalized by the enzyme nitric oxide syn-thetase. Two ixoenzymes have been characterized from this enzyme: a constitutive isoenzyme activated by hormones produced by the endothelial cells and acting on smooth muscle relaxing properties and the other, an inducible isoenzyme whose synthesis is stimulated by cytokines, and produced by macrophages. As pregnancy progresses, the concentrations of _GCB_NO, its metabolites, nitrates and nitrites, cGMP and the synthesizing enzyme, nitric oxide synthetase, increase parallelly until reaching a maximum peak before birth. It is considered that _GCB_NO is the molecule that maintains the typical vasodilated tone during prgnancy. During preeclampsia, this free radical, as well as its metabolites are found to be significantly decreased, in addition, the administration of _GCB_NO donors or of the precursor of L-arginine reverts the vascular abnormalities of this condition. The mechanism of action behind _GCB_NO on the vascular endothelium is by its stimulating effect on the enzyme cyclase guanilate, causing an increase in cGMP concentration and the relaxation of the smooth muscle. The nitric oxide generates by macrophages acts as a defense mechanism when linked with other radicals as the superoxide anion (O[sub2]). [ABSTRACT FROM AUTHOR] more...

RESUMEN Los productos de la peroxidación, los radicales libres y los compuestos antioxidantes aumentan notablemente durante la ovulación, la implantación y a medida que transcurre la gestación. La concentración del radical anión superóxido (O[sub2-]) aumenta aproximadamente seis veces en el proestro, mientras que su enzima reguladora, la superóxido dismutasa, disminuye. La presencia del radical superóxido está relacionada con el edema y la proliferación celular del estro. Este radical también está relacionado con el aumento de la fluidez y polaridad de las membranas durante la implantación. A medida que evoluciona la preñez aumentan los productos de lipoperoxidación y los compuestos antioxidantes, sugiriendo que los lipoperóxidos durante esta etapa evocan a los mecanismos de defensa, de tal manera que al final de la gestación los antioxidantes superan a los fenómenos peroxidativos. Por otro lado, el radical óxido nítrico ha cobrado gran importancia durante la gestación, ya que es considerado como uno de los relajantes mas potentes del músculo liso. La inhibición de su síntesis provoca signos semejantes a los de pre-eclampsia y su administración logra revertir muchas alteraciones vasculares. El papel de los radicales libres no se limita a efectos nocivos, sino que oportunamente y en concentraciones adecuadas, éstos participan como inductores de factores de crecimiento o en la fluidez de las membranas.SUMMARY The peroxidation products, the free radicals, and the antioxidants compounds notable increase durang ovulation, implantation, and pregnancy evolution.

Purpose: Prior evidence suggests a progression-free survival (PFS) benefit from adding metastasis-directed therapy (MDT) to standard-of-care (SOC) systemic therapy for patients with some oligometastatic solid tumors. Randomized trials testing this hypothesis in breast cancer have yet to be published. We sought to determine whether adding MDT to SOC systemic therapy improves PFS in oligometastatic breast cancer., Methods and Materials: External Beam Radiation to Eliminate Nominal Metastatic Disease is a multicenter phase 2 randomized basket trial testing the addition of MDT to SOC systemic therapy in patients with ≤5 metastases (NCT03599765). Patients were randomly assigned 1:1 to MDT (definitive local treatment to all sites of disease, plus SOC systemic therapy) or to SOC systemic therapy-only. Primary endpoint was PFS, and secondary endpoints included overall survival, time to subsequent line of systemic therapy, and time to the appearance of new metastases. Exploratory analyses included quality of life and systemic immune response measures., Results: From September 2018 through July 2022, 22 and 21 patients were randomly assigned to the MDT and no-MDT arms, respectively. At a median follow-up of 24.8 months, PFS was not improved with the addition of MDT to SOC systemic therapy (median PFS 15.6 months MDT vs 24.9 months no-MDT [hazard ratio, 0.91; 95% CI, 0.34-2.48; P = .86]). Similarly, MDT did not improve overall survival, time to subsequent line of systemic therapy, or time to the appearance of new metastases (all P > .05). No significant differences were found in quality of life measures, systemic T-cell activation, or T-cell stimulatory cytokine concentration., Conclusions: Among patients with oligometastatic breast cancer, the addition of MDT to SOC systemic therapy did not improve PFS. These findings suggest that MDT may have no systemic benefit in otherwise unselected patients with oligometastatic breast cancer, although this trial was limited by a heterogeneous and small sample size and overperformance of both treatment arms., (Copyright © 2024 Elsevier Inc.

Purpose: Precision medicine according to molecularly defined subgroups offers great potential to improve outcomes for patients with metastatic lung adenocarcinoma. This study describes clinical outcomes and the impact of co-occurring genetic alterations on outcomes following stereotactic radiosurgery (SRS) among patients with Kirsten rat sarcoma viral oncogene homolog (KRAS)-mutant lung adenocarcinoma., Methods and Materials: A total of 195 patients with KRAS-mutant lung adenocarcinoma were treated with SRS for brain metastases (BMs) between 2014 and 2018 with follow-up until 2022 or death. Coprimary outcomes were median overall survival (OS) and intracranial progression-free survival (iPFS); univariable and multivariable Cox regression models and Kaplan-Meier survival analysis were used., Results: Median follow-up from the date of BM diagnosis was 11 months. Median OS and iPFS for the cohort were 27.7 months (95% CI, 19.7-36.8) and 22.1 months (95% CI, 16.8-48.9), respectively. Lesion-level local control at 12 and 24 months was 89.9% and 87.5%, respectively. In a multivariable Cox regression model, inferior OS was associated with coalterations in KEAP1 and STK11 (hazard ratio [HR], 1.94; 95% CI, 1.04-3.62; q = 0.087), progressive (HR, 3.41; 95% CI, 1.38-8.39; q = 0.087), and mixed response (HR, 3.52; 95% CI, 1.2-10.3; q = 0.092) extracranial disease, and 6 or more BMs at time of diagnosis (HR, 2.58; 95% CI, 1.22-6.63; q = 0.087). Positive programmed death ligand 1 status was associated with improved OS (HR, 0.57; 95% CI, 0.37-0.87; P = .01). Inferior iPFS was associated with chemotherapy before SRS (HR, 2.69; 95% CI, 1.42-5.09; q = 0.04) and age >65 years (HR, 2.21; 95% CI, 1.25-3.93; q = 0.055). KRAS G12C was not associated with differences in iPFS, OS, or type of intracranial progression event following SRS., Conclusions: Coalteration of KRAS and KEAP1/STK11 was associated with inferior OS, but not iPFS. Similar outcomes were found in patients harboring KRAS G12C and non-G12C mutant non-small cell lung cancer BMs. Further understanding of molecularly characterized subgroups will be critical in driving personalized radiation therapy for patients with lung cancer BMs., (Copyright © 2025 Elsevier Inc.

Background/purpose: The circadian clock governs the expression of genes related to immunity and DNA repair. We investigated whether the time of day of radiotherapy and/or systemic therapy infusions (chemotherapy or anti-PD-L1) are associated with disease control and survival in locally advanced non-small cell lung cancer (LA-NSCLC)., Materials/methods: 178 consecutive patients with inoperable LA-NSCLC who received definitive chemoradiotherapy followed by durvalumab between 5/2017-8/2022 were reviewed. Outcomes evaluated included progression-free survival (PFS), distant metastasis-free survival (DMFS), locoregional control (LRC), and overall survival (OS)., Results: At a median follow up of 48.0 mo from durvalumab initiation, median PFS and OS were 26.2 mo and 50.0 mo, respectively. Median LRC and DMFS were not reached and 41.0 mo, respectively. Receiving > 50 % (N = 23) versus ≤ 50 % (N = 155) of radiotherapy treatments within 3 h of sunset was associated with younger age; otherwise, there were no other differences between cohorts. There were no significant differences in characteristics between patients who received > 50 % (N = 23) versus ≤ 50 % (N = 155) of durvalumab infusions within 3 h of sunset. On multivariable analysis, receiving > 50 % of radiotherapy treatments within 3 h of sunset was independently associated with reduced risk for progression (HR 0.39, p = 0.017) and distant metastasis (HR 0.27, p = 0.007); conversely, receiving > 50 % of durvalumab infusions within 3 h of sunset was independently associated with increased risk for distant metastasis (HR 2.13, p = 0.025). The timing of chemotherapy was not associated with disease outcomes., Conclusion: The time of day of radiotherapy and durvalumab infusion may be associated with disease control in LA-NSCLC, and the optimal time of treatment depends on the treatment modality., 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 oligometastatic disease state is defined as an intermediate state between localized cancer and widespread systemic metastases. Oligoprogression is defined as a subgroup in which limited metastatic areas are progressing in the background of oligometastatic or polymetastatic disease, whereas oligopersistent disease refers to an induced state in which formerly polymetastatic disease responds to treatment and decreases to fewer than 5 sites of active disease. With modern improvements in systemic therapy for patients with non-small cell lung cancer, including immunotherapies and targeted therapies, there may be a role for local therapy in selected patients with limited metastases-a subset of patients with potentially curable metastatic disease. Improved imaging techniques and advancements in highly conformal delivery of radiotherapy with stereotactic body radiation therapy have increased interest in using ablative radiotherapy or surgery as local consolidation therapy to improve patient outcomes. In this review, we define the oligoprogressive and oligopersistent disease states in patients with non-small cell lung cancer and discuss the evidence for the treatment and management of this patient population, including recent prospective trials and future directions in the selection of patients who will benefit most from local therapy. more...

Background: Alterations in forkhead box A1 (FOXA1), a pioneer transcription factor, are associated with poor prognosis in breast cancer and prostate cancer. We characterized FOXA1 genomic alterations and their clinical impacts in a large pan-cancer cohort from the American Association for Cancer Research Genomics, Evidence, Neoplasia, Information, Exchange database., Methods: FOXA1 alterations were characterized across more than 87 000 samples from more than 30 cancer types for primary and metastatic tumors alongside patient characteristics and clinical outcomes. FOXA1 alterations were queried in the Memorial Sloan Kettering - Metastatic Events and Tropisms (MSK-MET) cohort (a GENIE subset), allowing definition of hazard ratios (HRs) and survival estimates based on Cox proportional hazard models., Results: FOXA1 was altered in 1869 (2.1%) samples, with distinct patterns across different cancers: prostate cancer enriched with indel-inframe alterations, breast cancer with missense mutations, and lung cancers with copy number amplifications. Of 74 715 samples with FOXA1 copy number profiles, amplification was detected in 834 (1.1%). Amplification was most common in non-small cell lung cancer (NSCLC; 3% in primary; 6% in metastatic) and small cell lung cancer (4.1% primary; 3.5% metastatic), followed by breast cancer (2% primary; 1.6% metastatic) and prostate cancer (2.2% primary; 1.6% metastatic). Copy number amplifications were associated with decreased overall survival in NSCLC (HR = 1.45, 95% confidence interval [CI] = 1.06 to 1.99; P = .02), breast cancer (HR = 3.04, 95% CI = 1.89 to 4.89; P = 4e-6), and prostate cancer (HR = 1.94, 95% CI = 1.03 to 3.68; P = .04). Amplifications were associated with widespread metastases in NSCLC, breast cancer, and prostate cancer., Conclusions: FOXA1 demonstrates distinct alteration profiles across cancer sites. Our findings suggest an association between FOXA1 amplification and enhanced metastatic potential and decreased survival, highlighting prognostic and therapeutic potential in breast cancer, prostate cancer, and NSCLC., (© The Author(s) 2024.

Abstract: Osteoarthritis (OA) is a highly prevalent and disabling joint disease, characterized by pathological progressive joint deformation and clinical symptoms of pain. Disease-modifying treatments remain unavailable, and pain-mitigation is often suboptimal, but recent studies suggest beneficial effects by inhibition of the voltage-gated sodium channel Na V 1.7. We previously identified compound 194 as an indirect inhibitor of Na V 1.7 by preventing SUMOylation of the Na V 1.7-trafficking protein, collapsin response mediator protein 2. Compound 194 reduces the functional activity of Na V 1.7 channels and produces effective analgesia in a variety of acute and neuropathic pain models. However, its effectiveness has not yet been evaluated in models of OA. Here, we explore the effects of 194 on pain-related outcomes in the OA-like monoiodoacetate model using behavioral assessment, biochemistry, novel in vivo fiber photometry, and patch clamp electrophysiology. We found that the monoiodoacetate model induced (1) increased pain-like behaviors and calcium responses of glutamatergic neurons in the parabrachial nucleus after evoked cold and mechanical stimuli, (2) conditioned place aversion to mechanical stimulation, (3) functional weight bearing asymmetry, (4) increased sodium currents in dorsal root ganglia neurons, and (5) increased calcitonin gene-related peptide-release in the spinal cord. Crucially, administration of 194 improved all these pain-related outcomes. Collectively, these findings support indirect inhibition of Na V 1.7 as an effective treatment of OA-related pain through the inhibition of collapsin response mediator protein 2-SUMOylation via compound 194., (Copyright © 2024 International Association for the Study of Pain.) more...

Introduction: No definitive answers currently exist regarding optimal first-line therapy for HER2-mutant NSCLC. Access to rapid tissue sequencing is a major barrier to precision drug development in the first-line setting. ctDNA analysis has the potential to overcome these obstacles and guide treatment., Methods: We retrospectively analyzed patients with metastatic HER2-mutant NSCLC who underwent prospective clinical ctDNA sequencing and received systemic therapy at Memorial Sloan Kettering Cancer Center (MSK) from January 2016 to September 2022. HER2 mutations were identified by next-generation sequencing through MSK-IMPACT, MSK-ACCESS or Resolution ctDx LungTM assay. Primary endpoints were time to the next treatment (TTNT) and overall survival (OS)., Results: Sixty-three patients were included in the primary analysis. Chemoimmunotherapy (33/63, 52.4 %) was the predominant first-line treatment with a median TTNT of 5.1 months (95 %CI 4.1 - 6.1) whereas 55.0 % (22/40) of patients who received second-line T-DXd obtained a median TTNT of 9.2 m (95 % CI, 0-22.2). Plasma ctDNA was tested before first-line therapy in 40 patients with a median OS of 28.0 months (95 % CI 21-34), in whom 31 patients (78.0 %) had detectable ctDNA. HER2 mutations were detected on ctDNA with a median turnaround time of 13 days, occasionally co-occurred with EGFR and MET alterations and were tracked longitudinally correlating with treatment response. Patients with detectable baseline ctDNA had significantly shorter OS (hazard ratio (HR), 5.25; 95 % CI, 1.2-23.9; p = 0.019)., Conclusion: Chemoimmunotherapy remains a major treatment option for metastatic HER2-mutant NSCLC. ctDNA can rapidly detect HER2 and co-mutations, and it has the potential to guide and monitor optimal first-line therapy. As a negative prognostic biomarker, detectable ctDNA at baseline would need to be taken into account for patient selection in future studies., Competing Interests: Declaration of Competing Interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Bob T.

Objective: To generate a prediction model for selection of treatment modality for early-stage non-small cell lung cancer (NSCLC)., Summary Background Data: Stereotactic body radiotherapy (SBRT) and minimally invasive surgery (MIS) are used in the local treatment of early-stage NSCLC. However, selection of patients for either SBRT or MIS remains challenging, due to the multitude of factors influencing the decision-making process., Methods: We analyzed 1291 patients with clinical stage I NSCLC treated with intended MIS or SBRT from January 2020 to July 2023. A prediction model for selection for SBRT was created based on multivariable logistic regression analysis. The receiver operating characteristic curve analysis stratified the cohort into 3 treatment-related risk categories. Post-procedural outcomes, recurrence and overall survival (OS) were investigated to assess the performance of the model., Results: In total, 1116 patients underwent MIS and 175 SBRT. The prediction model included age, performance status, previous pulmonary resection, MSK-Frailty score, FEV1 and DLCO, and demonstrated an area-under-the-curve of 0.908 (95%CI, 0.876-0.938). Based on the probability scores (n=1197), patients were stratified into a low-risk (MIS, n=970 and SBRT, n=28), intermediate-risk (MIS, n=96 and SBRT, n=53) and high-risk category (MIS, n=10 and SBRT, n=40). Treatment modality was not associated with OS (HR of SBRT, 1.67 [95%CI: 0.80-3.48]; P=0.20)., Conclusion: Clinical expertise can be translated into a robust predictive model, guiding the selection of stage I NSCLC patients for MIS versus SBRT and effectively categorizing them into three distinct risk groups.

Background and Purpose: Radiation pneumonitis (RP) is a common side effect of thoracic radiotherapy and often has a long course characterized by acute exacerbations and progression to permanent lung fibrosis. There are no validated biomarkers of prognosis in patients diagnosed with RP., Materials and Methods: We analyzed a time course of serum chemokines, cytokines, and other proteins from patients with grade 2+ RP in a randomized clinical trial of a steroid taper plus nintedanib, a multiple tyrosine kinase inhibitor, versus placebo plus a steroid taper for the treatment of RP. Weighted gene correlation network analysis (WGCNA) and univariable zero inflated Poisson models were used to identify groups of correlated analytes and their associations with clinical outcomes., Results: Thirty enrolled patients had biomarker data available, and 17 patients had enough analytes tested for network analysis. WGNCA identified ten analytes, including transforming growth factor beta-1 (TGF-β1), monocyte chemoattractant protein-1 (MCP-1), and platelet-derived growth factor (PDGF), that in aggregate were correlated with the occurrence of pulmonary exacerbations (p = 0.008), the total number of acute pulmonary exacerbations (p = 0.002), and treatment arm (p = 0.036). By univariable analysis, an increase in rate of change of two components of the RP module were associated with an increased incidence rate of pulmonary exacerbations: interleukin 5 (IL-5, incidence rate ratio (IRR) 1.02, 95% CI 1.01-1.04, p = 0.002), and tumor necrosis factor superfamily 12 (TNFSF12, IRR 1.06, CI 1-1.11, p = 0.036). An increased slope of epidermal growth factor (EGF) was associated with a decreased incidence rate of exacerbations (IRR 0.94, CI 0.89-1, p = 0.036)., Conclusion: We identified a panel of serum biomarkers that showed association with nintedanib treatment and acute pulmonary exacerbations in patients with RP. A confirmatory study will be needed to validate this panel for use as a prognostic tool in patients with RP., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: AR previously consulted for Boehringer Ingelheim.

Purpose: Larger tumors are underrepresented in most prospective trials on stereotactic body radiation therapy (SBRT) for inoperable non-small cell lung cancer (NSCLC). We performed this phase 1 trial to specifically study the maximum tolerated dose (MTD) of SBRT for NSCLC >3 cm., Methods and Materials: A 3 + 3 dose-escalation design (cohort A) with an expansion cohort at the MTD (cohort B) was used. Patients with inoperable NSCLC >3 cm (T2-4) were eligible. Select ipsilateral hilar and single-station mediastinal nodes were permitted. The initial SBRT dose was 40 Gy in 5 fractions, with planned escalation to 50 and 60 Gy in 5 fractions. Adjuvant chemotherapy was mandatory for cohort A and optional for cohort B, but no patients in cohort B received chemotherapy. The primary endpoint was SBRT-related acute grade (G) 4+ or persistent G3 toxicities (Common Terminology Criteria for Adverse Events version 4.03). Secondary endpoints included local failure (LF), distant metastases, disease progression, and overall survival., Results: The median age was 80 years; tumor size was >3 cm and ≤5 cm in 20 (59%) and >5 cm in 14 patients (41%). In cohort A (n = 9), 3 patients treated to 50 Gy experienced G3 radiation pneumonitis (RP), thus defining the MTD. In the larger dose-expansion cohort B (n = 25), no radiation therapy-related G4+ toxicities and no G3 RP occurred; only 2 patients experienced G2 RP. The 2-year cumulative incidence of LF was 20.2%, distant failure was 34.7%, and disease progression was 54.4%. Two-year overall survival was 53%. A biologically effective dose (BED) <100 Gy was associated with higher LF (P = .006); advanced stage and higher neutrophil/lymphocyte ratio were associated with greater disease progression (both P = .004)., Conclusions: Fifty Gy in 5 fractions is the MTD for SBRT to tumors >3 cm. A higher BED is associated with fewer LFs even in larger tumors. Cohort B appears to have had less toxicity, possibly due to the omission of chemotherapy., (Copyright © 2023 Elsevier Inc.

Importance: Insurance barriers to cancer care can cause significant patient and clinician burden., Objective: To investigate the association of insurance denial with changes in technique, dose, and time to delivery of radiation oncology treatment., Design, Setting, and Participants: In this single-institution cohort analysis, data were collected from patients with payer-denied authorization for radiation therapy (RT) from November 1, 2021, to December 8, 2022. Data were analyzed from December 15, 2022, to December 31, 2023., Exposure: Insurance denial for RT., Main Outcomes and Measures: Association of these denials with changes in RT technique, dose, and time to treatment delivery was assessed using χ2 tests., Results: A total of 206 cases (118 women [57.3%]; median age, 58 [range, 26-91] years) were identified. Most insurers (199 [96.6%]) were commercial payers, while 7 (3.4%) were Medicare or Medicare Advantage. One hundred sixty-one patients (78.2%) were younger than 65 years. Of 206 cases, 127 (61.7%) were ultimately authorized without any change to the requested RT technique or prescription dose; 56 (27.2%) were authorized after modification to RT technique and/or prescription dose required by the payer. Of 21 cases with required prescription dose change, the median decrease in dose was 24.0 (range, 2.3-51.0) Gy. Of 202 cases (98.1%) with RT delivered, 72 (34.9%) were delayed for a mean (SD) of 7.8 (9.1) days and median of 5 (range, 1-49) days. Four cases (1.9%) ultimately did not receive any authorization, with 3 (1.5%) not undergoing RT, and 1 (0.5%) seeking treatment at another institution., Conclusions and Relevance: In this cohort study of patients with payer-denied cases, most insurance denials in radiation oncology were ultimately approved on appeal; however, RT technique and/or effectiveness may be compromised by payer-mandated changes. Further investigation and action to recognize the time and financial burdens on clinicians and clinical effects on patients caused by insurance denials of RT is needed. more...

Objectives: Recent randomized trials have demonstrated a survival advantage with the use of local consolidative therapy in oligometastatic non-small cell lung cancer; however, the indications for and outcomes after pulmonary resection as a component of local consolidative therapy remain ill defined. We sought to characterize the perioperative and long-term survival outcomes among patients with resected oligometastatic non-small cell lung cancer., Methods: Patients presenting to a single center (2000-2017) with oligometastatic non-small cell lung cancer (≤3 synchronous metastases, intrathoracic nodal disease counted as a single site) who underwent resection of the primary tumor were retrospectively identified. Charts were reviewed, and demographic, clinical, pathologic, oncologic, and survival outcomes were recorded. Survival outcomes were analyzed from the date of surgery., Results: A total of 52 patients met inclusion criteria, among whom most (38, 73.1%) were ever smokers, had nonsquamous tumors (48, 92.3%), had no intrathoracic nodal disease (33, 63.5%), and had 1 to 2 sites of metastases (49, 94.2%). The majority (41, 78.9%) received systemic therapy, predominantly in the neoadjuvant setting (24/41, 58.5%). After resection, there were no 30- or 90-day deaths. After a median follow-up of 94.6 months (95% CI, 69.0-139.1), 37 patients (71.2%) progressed and 38 patients (73.1%) died. Median postoperative progression-free survival and overall survival were 9.4 (5.5-11.6) months and 51.7 (22.3-65.3) months, respectively., Conclusions: Pulmonary resection as a means of maximum locoregional control in oligometastatic non-small cell lung cancer is feasible and safe, and may be associated with durable long-term survival benefits. The frequency of systemic postoperative progression highlights an urgent need to characterize perioperative and oncologic outcomes after pulmonary resection in the current era of novel systemic therapies., Competing Interests: Conflict of Interest Statement S.G.S. has participated in advisory committees for Ethicon and the Peter MacCallum Cancer Center.

Purpose: Clinical trial participation continues to be low, slowing new cancer therapy development. Few strategies have been prospectively tested to address barriers to enrollment. We investigated the effectiveness of a physician audit and feedback report to improve clinical trial enrollment., Methods and Materials: We conducted a randomized quality improvement study among radiation oncologists at a multisite tertiary cancer network. Physicians in the intervention group received quarterly audit and feedback reports comparing the physician's trial enrollments with those of their peers. The primary outcome was trial enrollments., Results: Among physicians randomized to receive the feedback report (n = 30), the median proportion of patients enrolled during the study period increased to 6.1% (IQR, 2.6%-9.3%) from 3.2% (IQR, 1.1%-10%) at baseline. Among those not receiving the feedback report (n = 29), the median proportion of patients enrolled increased to 4.1% (IQR, 1.3%-7.6%) from 1.6% (IQR, 0%-4.1%) at baseline. There was a nonsignificant change in the proportion of enrollments associated with receiving the feedback report (-0.6%; 95% CI, -3.0% to 1.8%; P = .6). Notably, there was an interaction between baseline trial accrual and receipt of feedback reports (P = .005), with enrollment declining among high accruers. There was an increase in enrollment throughout the study, regardless of study group (P = .001)., Conclusions: In this study, a positive effect of physician audit and feedback on clinical trial enrollment was not observed. Future efforts should avoid disincentivizing high accruers and might consider pairing feedback with other patient- or physician-level strategies. The increase in trial enrollment in both groups over time highlights the importance of including a comparison group in quality improvement studies to reduce confounding from secular trends., (Copyright © 2023 Elsevier Inc.

Purpose: Hispanic and Latinx people in the United States are the fastest-growing ethnic group. However, previous studies in non-small-cell lung cancer (NSCLC) often analyze these diverse communities in aggregate. We aimed to identify differences in NSCLC stage at diagnosis in the US population, focusing on disaggregated Hispanic/Latinx individuals., Methods: Data from the National Cancer Database from 2004 to 2018 identified patients with primary NSCLC. Individuals were disaggregated by racial and ethnic subgroup and Hispanic country of origin. Ordinal logistic regression adjusting for age, facility type, income, educational attainment, comorbidity index, insurance, and year of diagnosis was used to create adjusted odds ratios (aORs), with higher odds representing diagnosis at later-stage NSCLC., Results: Of 1,565,159 patients with NSCLC, 46,616 were Hispanic/Latinx (3.0%). When analyzed in the setting of race and ethnicity, Hispanic patients were more likely to be diagnosed with metastatic disease compared with non-Hispanic White (NHW) patients: 47.0% for Hispanic Black, 46.0% Hispanic White, and 44.3% of Hispanic other patients versus 39.1% of non-Hispanic White patients ( P < .001 for all). By country of origin, 51.4% of Mexican, 41.7% of Puerto Rican, 44.6% of Cuban, 50.8% of South or Central American, 48.4% of Dominican, and 45.6% of other Hispanic patients were diagnosed with metastatic disease, compared with 39.1% of NHWs. Conversely, 20.2% of Mexican, 26.9% of Puerto Rican, 24.2% of Cuban, 22.5% of South or Central American, 23.7% of Dominican, and 24.5% of other Hispanic patients were diagnosed with stage I disease, compared with 30.0% of NHWs. All Hispanic groups were more likely to present with later-stage NSCLC than NHW patients (greatest odds for Mexican patients, aOR, 1.44; P < .001)., Conclusion: Hispanic/Latinx patients with non-small-cell lung cancer were more likely to be diagnosed with advanced disease compared with NHWs. Disparities persisted upon disaggregation by both race and country of origin, with over half of Mexican patients with metastatic disease at diagnosis. Disparities among Hispanic/Latinx groups by race and by country of origin highlight the shortcomings of treating these groups as a monolith and underscore the need for disaggregated research and targeted interventions. more...

Radiation pneumonitis (RP) that develops early (i.e., within 3 mo) (RP Early ) after completion of concurrent chemoradiation (cCRT) leads to treatment discontinuation and poorer survival for patients with stage III non-small cell lung cancer. Since no RP Early risk model exists, we explored whether published RP models and pretreatment 18 F-FDG PET/CT-derived features predict RP Early Methods: One hundred sixty patients with stage III non-small cell lung cancer treated with cCRT and consolidative immunotherapy were analyzed for RP Early Three published RP models that included the mean lung dose (MLD) and patient characteristics were examined. Pretreatment 18 F-FDG PET/CT normal-lung SUV featured included the following: 10th percentile of SUV (SUV P10 ), 90th percentile of SUV (SUV P90 ), SUV max , SUV mean , minimum SUV, and SD. Associations between models/features and RP Early were assessed using area under the receiver-operating characteristic curve (AUC), P values, and the Hosmer-Lemeshow test (pHL). The cohort was randomly split, with similar RP Early rates, into a 70%/30% derivation/internal validation subset. Results: Twenty (13%) patients developed RP Early Predictors for RP Early were MLD alone (AUC, 0.72; P = 0.02; pHL, 0.87), SUV P10 , SUV P90, and SUV mean (AUC, 0.70-0.74; P = 0.003-0.006; pHL, 0.67-0.70). The combined MLD and SUV P90 model generalized in the validation subset and was deemed the final RP Early model (RP Early risk = 1/[1+e (- x ) ]; x = -6.08 + [0.17 × MLD] + [1.63 × SUV P90 ]). The final model refitted in the 160 patients indicated improvement over the published MLD-alone model (AUC, 0.77 vs. 0.72; P = 0.0001 vs. 0.02; pHL, 0.65 vs. 0.87). Conclusion: Patients at risk for RP Early can be detected with high certainty by combining the normal lung's MLD and pretreatment 18 F-FDG PET/CT SUV P90 This refined model can be used to identify patients at an elevated risk for premature immunotherapy discontinuation due to RP Early and could allow for interventions to improve treatment outcomes., (© 2024 by the Society of Nuclear Medicine and Molecular Imaging.) more...

Background: The objective of this study is to determine the outcomes and toxicities of patients with malignant pleural mesothelioma (MPM) treated with stereotactic body radiotherapy (SBRT)., Materials and Methods: Data were extracted from an institutional tumor registry for patients diagnosed with mesothelioma and treated with SBRT. Kaplan-Meier and Cox regression analyses were employed to determine local control (LC) and overall survival (OS)., Results: Forty-four patients with 59 total treated tumors from December 2006 to April 2022 were identified. Fifty-one (86.4 %) cases had oligoprogressive disease (five sites or less). The median prescription dose delivered was 3000 cGy in 5 fractions (range: 2700-6000 cGy in 3-8 fractions). Fifty-one (86.4 %) tumors were in the pleura, 4 (6.8 %) spine, 2 (3.4 %) bone, 1 (1.7 %) brain, and 1 (1.7 %) pancreas. The median follow-up from SBRT completion for those alive at last follow-up was 28 months (range: 14-52 months). The most common toxicities were fatigue (50.8 %), nausea (22.0 %), pain flare (15.3 %), esophagitis (6.8 %), dermatitis (6.8 %), and pneumonitis (5.1 %). There were no grade ≥ 3 acute or late toxicities. There were 2 (3.4 %) local failures, one of the pleura and another of the spine. One-year LC was 92.9 % (95 % CI: 74.6-98.2 %) for all lesions and 96.3 % (95 % CI: 76.5-99.5 %) for pleural tumors. One-year LC was 90.9 % (95 % CI: 68.1-97.6 %) for epithelioid tumors and 92.1 % (95 % CI: 72.1-98.0 %) for oligoprogressive tumors. One-year OS from time of SBRT completion was 36.4 % (95 % CI: 22.6-50.3 %). On multivariable analysis, KPS was the lone significant predictor for OS (p = 0.029)., Conclusions: Our single-institutional experience on patients with MPM suggests that SBRT is safe with a low toxicity profile and potentially achieve good local control., Competing Interests: Declaration of competing interest The authors declare the following financial interests/personal relationships which may be considered as potential competing interests: Jacob Y.

Background: Cancer cachexia is a syndrome of unintentional weight loss resulting in progressive functional impairment. Knowledge of radiation therapy utilization in patients with cancer cachexia is limited. We evaluated the use of curative and palliative-intent radiation for the management of patients with non-small cell lung cancer (NSCLC) with cachexia to determine whether tumor-directed therapy affected cachexia-associated outcomes., Methods: Using an Institutional Tumor Registry, we evaluated all patients with stages of NSCLC treated at a tertiary care system from 2006 to 2013. We adopted the international consensus definition for cachexia, with staging designated by the registry and positron emission tomography. Radiotherapy delivery and intent were retrospectively assessed., Results: In total, 1330 patients with NSCLC were analyzed. Curative-intent radiotherapy was utilized equally between patients with cachexia and non-cachexia with stages I to III NSCLC. Conversely, significantly more patients with stage IV disease and cachexia received palliative radiotherapy versus those without (74% vs 63%, P = 0.006). Cachexia-associated survival was unchanged irrespective of tumor-directed radiation therapy with curative or palliative intent. In fact, pretreatment cachexia was associated with reduced survival for patients with stage III NSCLC receiving curative-intent radiotherapy (median survival = 23.9 vs 15.0 mo, P = 0.009). Finally, multivariate analysis identified pretreatment cachexia as an independent variable associated with worsened survival (hazard ratio = 1.31, CI: 1.14,1.52)., Conclusion: Patients with advanced NSCLC with cachexia received more palliative-intent radiation than those without weight loss. Tumor-directed therapy in either a curative or palliative approach failed to alter cachexia patient survival across all stages of the disease. These findings offer critical information on the appropriate utilization of radiation in the management of patients with NSCLC with cachexia., Competing Interests: B.S.G. was supported in part by the National Center for Advancing Translational Sciences of the National Institutes of Health grants TL1TR001104 and UL1TR001105.

Background: Most patients with metastatic cancer eventually develop resistance to systemic therapy, with some having limited disease progression (ie, oligoprogression). We aimed to assess whether stereotactic body radiotherapy (SBRT) targeting oligoprogressive sites could improve patient outcomes., Methods: We did a phase 2, open-label, randomised controlled trial of SBRT in patients with oligoprogressive metastatic breast cancer or non-small-cell lung cancer (NSCLC) after having received at least first-line systemic therapy, with oligoprogression defined as five or less progressive lesions on PET-CT or CT. Patients aged 18 years or older were enrolled from a tertiary cancer centre in New York, NY, USA, and six affiliated regional centres in the states of New York and New Jersey, with a 1:1 randomisation between standard of care (standard-of-care group) and SBRT plus standard of care (SBRT group). Randomisation was done with a computer-based algorithm with stratification by number of progressive sites of metastasis, receptor or driver genetic alteration status, primary site, and type of systemic therapy previously received. Patients and investigators were not masked to treatment allocation. The primary endpoint was progression-free survival, measured up to 12 months. We did a prespecified subgroup analysis of the primary endpoint by disease site. All analyses were done in the intention-to-treat population. The study is registered with ClinicalTrials.gov, NCT03808662, and is complete., Findings: From Jan 1, 2019, to July 31, 2021, 106 patients were randomly assigned to standard of care (n=51; 23 patients with breast cancer and 28 patients with NSCLC) or SBRT plus standard of care (n=55; 24 patients with breast cancer and 31 patients with NSCLC). 16 (34%) of 47 patients with breast cancer had triple-negative disease, and 51 (86%) of 59 patients with NSCLC had no actionable driver mutation. The study was closed to accrual before reaching the targeted sample size, after the primary efficacy endpoint was met during a preplanned interim analysis. The median follow-up was 11·6 months for patients in the standard-of-care group and 12·1 months for patients in the SBRT group. The median progression-free survival was 3·2 months (95% CI 2·0-4·5) for patients in the standard-of-care group versus 7·2 months (4·5-10·0) for patients in the SBRT group (hazard ratio [HR] 0·53, 95% CI 0·35-0·81; p=0·0035). The median progression-free survival was higher for patients with NSCLC in the SBRT group than for those with NSCLC in the standard-of-care group (10·0 months [7·2-not reached] vs 2·2 months [95% CI 2·0-4·5]; HR 0·41, 95% CI 0·22-0·75; p=0·0039), but no difference was found for patients with breast cancer (4·4 months [2·5-8·7] vs 4·2 months [1·8-5·5]; 0·78, 0·43-1·43; p=0·43). Grade 2 or worse adverse events occurred in 21 (41%) patients in the standard-of-care group and 34 (62%) patients in the SBRT group. Nine (16%) patients in the SBRT group had grade 2 or worse toxicities related to SBRT, including gastrointestinal reflux disease, pain exacerbation, radiation pneumonitis, brachial plexopathy, and low blood counts., Interpretation: The trial showed that progression-free survival was increased in the SBRT plus standard-of-care group compared with standard of care only. Oligoprogression in patients with metastatic NSCLC could be effectively treated with SBRT plus standard of care, leading to more than a four-times increase in progression-free survival compared with standard of care only. By contrast, no benefit was observed in patients with oligoprogressive breast cancer. Further studies to validate these findings and understand the differential benefits are warranted., Funding: National Cancer Institute., Competing Interests: Declaration of interests CJT is on the advisory board of Nanobiotix and Varian Medical, and received consultation fees and honorarium support from Varian Medical.

There is a need to identify predictive biomarkers to guide treatment strategies in stage III non-small cell lung cancer (NSCLCs). In this multi-institutional cohort of 197 patients with stage III NSCLC treated with concurrent chemoradiation (cCRT) and durvalumab consolidation, we identify that low tumor aneuploidy is independently associated with prolonged progression-free survival (HR 0.63; p=0.03) and overall survival (HR 0.50; p=0.03). Tumors with high aneuploidy had a significantly greater incidence of distant metastasis and shorter median distant-metastasis free survival (p=0.04 and p=0.048, respectively), but aneuploidy level did not associate with local-regional outcomes. Multiplexed immunofluorescence analysis in a cohort of NSCLC found increased intratumoral CD8-positive, PD-1-positive cells, double-positive PD-1 CD8 cells, and FOXP3-positive T-cell in low aneuploid tumors. Additionally, in a cohort of 101 patients treated with cCRT alone, tumor aneuploidy did not associate with disease outcomes. These data support the need for upfront treatment intensification strategies in stage III NSCLC patients with high aneuploid tumors and suggest that tumor aneuploidy is a promising predictive biomarker., Competing Interests: Competing interests: NS reports research funding from Novartis.

Infiltration of tumor by T cells is a prerequisite for successful immunotherapy of solid tumors. In this study, we investigate the influence of tumor-targeted radiation on chimeric antigen receptor (CAR) T-cell therapy tumor infiltration, accumulation, and efficacy in clinically relevant models of pleural mesothelioma and non-small cell lung cancers. We use a nonablative dose of tumor-targeted radiation prior to systemic administration of mesothelin-targeted CAR T cells to assess infiltration, proliferation, antitumor efficacy, and functional persistence of CAR T cells at primary and distant sites of tumor. A tumor-targeted, nonablative dose of radiation promotes early and high infiltration, proliferation, and functional persistence of CAR T cells. Tumor-targeted radiation promotes tumor-chemokine expression and chemokine-receptor expression in infiltrating T cells and results in a subpopulation of higher-intensity CAR-expressing T cells with high coexpression of chemokine receptors that further infiltrate distant sites of disease, enhancing CAR T-cell antitumor efficacy. Enhanced CAR T-cell efficacy is evident in models of both high-mesothelin-expressing mesothelioma and mixed-mesothelin-expressing lung cancer-two thoracic cancers for which radiotherapy is part of the standard of care. Our results strongly suggest that the use of tumor-targeted radiation prior to systemic administration of CAR T cells may substantially improve CAR T-cell therapy efficacy for solid tumors. Building on our observations, we describe a translational strategy of "sandwich" cell therapy for solid tumors that combines sequential metastatic site-targeted radiation and CAR T cells-a regional solution to overcome barriers to systemic delivery of CAR T cells., (©2023 American Association for Cancer Research.) more...

Background/purpose: Stereotactic body radiation therapy (SBRT) is standard for patients with inoperable early-stage NSCLC. We hypothesized that SBRT for sarcoma pulmonary metastases would achieve high rates of local control with acceptable toxicity and that patients with oligometastatic disease may achieve prolonged survival following SBRT., Materials/methods: This retrospective review included consecutive patients at our institution treated with SBRT for sarcoma pulmonary metastases. Cumulative incidence of local failure (LF) was estimated using a competing risks framework., Results: We identified 66 patients treated to 95 pulmonary metastases with SBRT. The median follow-up from the time of SBRT was 36 months (95% CI 34 - 53 months). The cumulative incidence of LF at 12 and 24 months was 3.1% (95% CI 0.9 - 10.6%) and 7.4% (95% CI 4.0% - 13.9%), respectively. The 12- and 24-month overall survival was 74% (95% CI 64 - 86%) and 49% (38 - 63%), respectively. Oligometastatic disease, intrathoracic only disease, and performance status were associated with improved survival on univariable analysis. Three patients had grade 2 pneumonitis, and one patient had grade 2 esophagitis. No patients had ≥ grade 3+ toxicities., Conclusion: To the best of our knowledge, this is the largest series of patients treated with SBRT for pulmonary sarcoma metastases. We observed that SBRT offers an effective alternative to surgical resection with excellent local control and low proportions of toxicity., 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 © 2023 Elsevier B.V.

The COVID-19 vaccination of prisoners and prison staff represents a public health intervention to reduce the impact of the pandemic in conglomerate settings. In Spanish prisons, the road map of the Ministry of Health was followed to protect the population at risk. We conducted a cross-sectional study to assess the acceptance of COVID-19 vaccination by prisoners and prison staff in a prison in Alicante, Spain. We analyzed data obtained through a standardized, self-administered, and anonymous questionnaire; 1016 prisoners and 288 prison staff responded to the survey. The majority of inmates and staff reported no history of symptomatic COVID-19, 90.15% and 91.66%, respectively. Respondents reported that 88.72% agreed to be vaccinated and 89.64% would recommend the vaccine to others. Approximately 89% believe that the benefit of getting vaccinated against COVID-19 is greater than the risk, and 70.55% reported that vaccination should be mandatory for inmates and staff to participate in some activities. The acceptance of COVID-19 vaccination among prisoners and prison staff is high in a Provincial Prison in Spain. Elevated acceptance of COVID-19 vaccination in prisons is a major factor in public health intervention and vaccine equity. more...

Background: Sensitive and reliable biomarkers for early detection of recurrence are needed to improve post-definitive radiation risk stratification, disease management, and outcomes for patients with unresectable early-stage or locally advanced non-small cell lung cancer (NSCLC) who are treated with definitive radiation therapy (RT). This prospective, multistate single-center, cohort study investigated the association of circulating tumor DNA (ctDNA) status with recurrence in patients with unresectable stage I-III NSCLC who underwent definitive RT., Methods: A total of 70 serial plasma samples from 17 NSCLC patients were collected before, during, and after treatment. A personalized, tumor-informed ctDNA assay was used to track a set of up to 16 somatic, single nucleotide variants in the associated patient's plasma samples., Results: Pre-treatment ctDNA detection rate was 82% (14/17) and varied based on histology and stage. ctDNA was detected in 35% (6/17) of patients at the first post-RT timepoint (median of 1.66 months following the completion of RT), all of whom subsequently developed clinical progression. At this first post-RT time point, patients with ctDNA-positivity had significantly worse progression-free survival (PFS) [hazard ratio (HR): 24.2, p=0.004], and ctDNA-positivity was the only significant prognostic factor associated with PFS (HR: 13.4, p=0.02) in a multivariate analysis. All patients who developed clinical recurrence had detectable ctDNA with an average lead time over radiographic progression of 5.4 months, and post-RT ctDNA positivity was significantly associated with poor PFS (p<0.0001)., Conclusion: Personalized, longitudinal ctDNA monitoring can detect recurrence early in patients with unresectable NSCLC patients undergoing curative radiation and potentially risk-stratify patients who might benefit most from treatment intensification., Competing Interests: NS reports research funding from Novartis.

Purpose: This joint guideline by American Society for Radiation Oncology (ASTRO) and the European Society for Radiotherapy and Oncology (ESTRO) was initiated to review evidence and provide recommendations regarding the use of local therapy in the management of extracranial oligometastatic non-small cell lung cancer (NSCLC). Local therapy is defined as the comprehensive treatment of all known cancer-primary tumor, regional nodal metastases, and metastases-with definitive intent., Methods: ASTRO and ESTRO convened a task force to address 5 key questions focused on the use of local (radiation, surgery, other ablative methods) and systemic therapy in the management of oligometastatic NSCLC. The questions address clinical scenarios for using local therapy, sequencing and timing when integrating local with systemic therapies, radiation techniques critical for oligometastatic disease targeting and treatment delivery, and the role of local therapy for oligoprogression or recurrent disease. Recommendations were based on a systematic literature review and created using ASTRO guidelines methodology., Results: Based on the lack of significant randomized phase 3 trials, a patient-centered, multidisciplinary approach was strongly recommended for all decision-making regarding potential treatment. Integration of definitive local therapy was only relevant if technically feasible and clinically safe to all disease sites, defined as 5 or fewer distinct sites. Conditional recommendations were given for definitive local therapies in synchronous, metachronous, oligopersistent, and oligoprogressive conditions for extracranial disease. Radiation and surgery were the only primary definitive local therapy modalities recommended for use in the management of patients with oligometastatic disease, with indications provided for choosing one over the other. Sequencing recommendations were provided for systemic and local therapy integration. Finally, multiple recommendations were provided for the optimal technical use of hypofractionated radiation or stereotactic body radiation therapy as definitive local therapy, including dose and fractionation., Conclusions: Presently, data regarding clinical benefits of local therapy on overall and other survival outcomes is still sparse for oligometastatic NSCLC. However, with rapidly evolving data being generated supporting local therapy in oligometastatic NSCLC, this guideline attempted to frame recommendations as a function of the quality of data available to make decisions in a multidisciplinary approach incorporating patient goals and tolerances., Competing Interests: Disclosures All task force members’ disclosure statements were reviewed before being invited and were shared with other task force members throughout the guideline's development.

Purpose: Radiation pneumonitis (RP) is the most common dose-limiting toxicity for thoracic radiation therapy. Nintedanib is used for the treatment of idiopathic pulmonary fibrosis, which shares pathophysiological pathways with the subacute phase of RP. Our goal was to investigate the efficacy and safety of nintedanib added to a prednisone taper compared with a prednisone taper alone in reducing pulmonary exacerbations in patients with grade 2 or higher (G2+) RP., Methods and Materials: In this phase 2, randomized, double-blinded, placebo-controlled trial, patients with newly diagnosed G2+ RP were randomized 1:1 to nintedanib or placebo in addition to a standard 8-week prednisone taper. The primary endpoint was freedom from pulmonary exacerbations at 1 year. Secondary endpoints included patient-reported outcomes and pulmonary function tests. Kaplan-Meier analysis was used to estimate the probability of freedom from pulmonary exacerbations. The study was closed early due to slow accrual., Results: Thirty-four patients were enrolled between October 2015 and February 2020. Of 30 evaluable patients, 18 were randomized to the experimental Arm A (nintedanib + prednisone taper) and 12 to the control Arm B (placebo + prednisone taper). Freedom from exacerbation at 1 year was 72% (confidence interval, 54%-96%) in Arm A and 40% (confidence interval, 20%-82%) in Arm B (1-sided, P = .037). In Arm A, there were 16 G2+ adverse events possibly or probably related to treatment compared with 5 in the placebo arm. There were 3 deaths during the study period in Arm A due to cardiac failure, progressive respiratory failure, and pulmonary embolism., Conclusions: There was an improvement in pulmonary exacerbations by the addition of nintedanib to a prednisone taper. Further investigation is warranted for the use of nintedanib for the treatment of RP., (Copyright © 2023 Elsevier Inc. All rights reserved.) more...

Although concurrent chemoradiation (CRT) and durvalumab consolidation has become a standard treatment for stage III non-small cell lung cancer (NSCLC), clinicopathologic and genomic factors associated with its efficacy remain poorly characterized. Here, in a multi-institutional retrospective cohort study of 328 patients treated with CRT and durvalumab, we identify that very high PD-L1 tumor proportion score (TPS) expression ( ≥ 90%) and increased tumor mutational burden (TMB) are independently associated with prolonged disease control. Additionally, we identify the impact of pneumonitis and its timing on disease outcomes among patients who discontinue durvalumab: compared to patients who experienced early-onset pneumonitis ( < 3 months) leading to durvalumab discontinuation, patients with late-onset pneumonitis had a significantly longer PFS (12.7 months vs not reached; HR 0.24 [95% CI, 0.10 to 0.58]; P = 0.001) and overall survival (37.2 months vs not reached; HR 0.26 [95% CI, 0.09 to 0.79]; P = 0.017). These findings suggest that opportunities exist to improve outcomes in patients with lower PD-L1 and TMB levels, and those at highest risk for pneumonitis., (© 2023. The Author(s).) more...

Purpose: ATM is the most commonly mutated DNA damage and repair gene in non-small cell lung cancer (NSCLC); however, limited characterization has been pursued., Experimental Design: Clinicopathologic, genomic, and treatment data were collected for 5,172 patients with NSCLC tumors which underwent genomic profiling. ATM IHC was performed on 182 NSCLCs with ATM mutations. Multiplexed immunofluorescence was performed on a subset of 535 samples to examine tumor-infiltrating immune cell subsets., Results: A total of 562 deleterious ATM mutations were identified in 9.7% of NSCLC samples. ATM-mutant (ATMMUT) NSCLC was significantly associated with female sex (P = 0.02), ever smoking status (P < 0.001), non-squamous histology (P = 0.004), and higher tumor mutational burden (DFCI, P < 0.0001; MSK, P < 0.0001) compared with ATM-wild-type (ATMWT) cases. Among 3,687 NSCLCs with comprehensive genomic profiling, co-occurring KRAS, STK11, and ARID2 oncogenic mutations were significantly enriched among ATMMUT NSCLCs (Q < 0.05), while TP53 and EGFR mutations were enriched in ATMWT NSCLCs. Among 182 ATMMUT samples with ATM IHC, tumors with nonsense, insertions/deletions, or splice site mutations were significantly more likely to display ATM loss by IHC (71.4% vs. 28.6%; P < 0.0001) compared with tumors with only predicted pathogenic missense mutations. Clinical outcomes to PD-(L)1 monotherapy (N = 1,522) and chemo-immunotherapy (N = 951) were similar between ATMMUT and ATMWT NSCLCs. Patients with concurrent ATM/TP53 mutations had significantly improved response rate and progression-free survival with PD-(L)1 monotherapy., Conclusions: Deleterious ATM mutations defined a subset of NSCLC with unique clinicopathologic, genomic, and immunophenotypic features. Our data may serve as resource to guide interpretation of specific ATM mutations in NSCLC., (©2023 American Association for Cancer Research.) more...
