This study aims to assess the QoL of premenopausal Chinese breast cancer women after receiving adjuvant chemotherapy.Patients and methods: Eligibility criteria included stage I–III breast cancer, premenopausal and age ≤45 years at cancer diagnosis and having received adjuvant chemotherapy within 3–10 years before entry to the present study. Patients’ background demographics at the time of breast cancer diagnosis, together with tumor characteristics and anticancer treatments, were collected. At the time of study entry, the menopausal status based on menstrual history, body mass index, and QoL (assessed using Functional Assessment of Cancer Therapy-Breast +4) were recorded.Results: Two hundred and eighty patients were recruited. Ninety-five patients (33.9%) underwent breast-conserving surgery, and nearly all (98.6%) underwent axillary dissection. For adjuvant therapies, 249 patients (88.9%) received anthracycline-containing chemotherapy and 79 (28.2%) received taxane-containing chemotherapy, while 68 (24.3%) received both. One hundred and eighty six patients (66.4%) received adjuvant radiotherapy, and 214 (76.4%) received adjuvant tamoxifen. The median time from breast cancer diagnosis to study entry was 5.01 years. QoL assessment at study entry revealed that older patients had worse social well-being (SWB; mean scores for age ≤40, 41–45, 46–50 and >50 years were 22.0, 19.3, 19.1 and 18.1, respectively, P=0.0442). Patients who underwent axillary dissection had worse scores for breast cancer subscale (BCS; mean score 22.2 vs. 28.3, P=0.0212). Patients who underwent taxane-containing chemotherapy had worse scores for arm subscale (mean score 13.8 vs. 15.3, P=0.0053).Conclusion: At a median follow-up of 5 years post-diagnosis, patients who were younger had fewer disturbances in their SWB. Patients who had axillary dissection had worse BCS scores, while those who received taxane had worse scores for arm subscale. Further studies are warranted for breast-specific QoL to address the specific issues encountered by breast cancer patients. Keywords: cytotoxic, QoL, FACT-B+4, cancer survivors breast, premenopausal

The aim of the study was to report the outcome of primary localized low-grade fibromyxoid sarcoma (LGFMS), sclerosing epithelioid fibrosarcoma (SEF), and hybrid LGFMS/SEF (H-LGFMS/SEF). Patients with primary localized LGFMS, SEF, or H-LGFMS/SEF, surgically treated with curative intent from January 2000 to September 2022, were enrolled from 14 countries and 27 institutions. Pathologic inclusion criteria were predefined by expert pathologists. The primary endpoint was overall survival (OS). Secondary endpoints were crude cumulative incidence (CCI) of local recurrence (LR), CCI of distant metastases (DM), and post-metastases OS (p-OS). Two hundred ninety-four patients (239 LGFMS, 32 SEF, and 23 H-LGFMS/SEF) were identified. At a median(m-) follow-up (FU) of 57.1 months, 12/294 patients died. The 5- and 10-year OS were 99.0% and 95.9% in LGFMS, 86.2% and 67.0% in SEF, and 84.8% and 84.8% in H-LGFMS/SEF, respectively. Predictors of worse OS included pathology, age at surgery, systemic therapy, and radiotherapy. LR developed in 13/294 (4.4%) patients. The observed m-time to LR was 10.7 months. The 5- and 10-yr CCI-LR were 4.7% in LGFMS and 6.6% in SEF, respectively. There were no LR events in H-LGFMS/SEF. The sole predictor of higher risk of LR was histology. DM developed in 23/294 (7.8%) patients. The observed m-time to DM was 28.2 months. The 5- and 10-yr CCI-DM were 1.3% and 2.7% in LGMFS, 29.9% and 57.7% in SEF, 48.9% and 48.9% in H-LGFMS/SEF, respectively. Predictors of higher risk of DM were histology, systemic therapy, and radiotherapy. Primary localized LGFMS treated with complete surgical resection has an excellent prognosis, while about 50% of H-LGFMS/SEF and SEF develop DM within 5 to 10 years. Very long-term FU is needed to understand absolute cure rates., Competing Interests: Conflicts of Interest and Source of Funding: The authors have disclosed that they have no significant relationships with, or financial interest in, any commercial companies pertaining to this article., (Copyright © 2024 The Author(s).

GLI1-altered mesenchymal tumors have recently emerged as a distinctive group of neoplasms characterized by GLI1 fusions or amplifications. Although there is clearly metastatic potential, the clinicopathologic features predicting for metastasis are currently unknown. Herein, we present 6 cases of GLI1-altered mesenchymal tumors with multiomics analysis. The median patient age was 50 years (range, 3-68 years). They arose from the extremities and trunk (2/6), head and neck region (2/6), and gastrointestinal tract (2/6). Histologically, they featured uniform round to ovoid cells with nested architecture and a rich vascular network. One case displayed abundant multinucleated giant cells. All stained positive for GLI1 (5/5) and CD56 (6/6). Molecularly, they featured GLI1 fusion (5/6) and amplification (1/6). Fusion partners included ACTB (3/5), TXNIP (1/5), and novel TUBA1B (1/5). Multiomics analysis revealed they possessed distinct expression and epigenomic profiles. All the 6 cases had follow-up information, with 5 of them having no evidence of disease at a median follow-up of 30 months (range, 17.3-102 months), and 1 case being died of disease with regional neck lymph node and bilateral lung metastasis at 81.5 months of follow-up. By incorporating cases reported in the literature, we analyzed clinicopathologic features of a total of 167 cases predictive of malignant behavior. We found that size ≥6 cm and mitotic count ≥5 per 10 high-power fields are predictive of metastasis. Cases with both high-risk features had significantly poorer survival. This study expands the literature database of GLI1-altered mesenchymal tumors and identifies features that can be used for risk stratification., (Copyright © 2024 United States & Canadian Academy of Pathology.

Background: The effect of supplements on mortality risk in patients with cancer remains uncertain and has scarcely been investigated in subgroups of patients with varying characteristics. This study aimed to investigate the association between two popular supplements, fish oil and glucosamine, and mortality risk in a large population-based cohort and determine whether cardiovascular health and clinical prognosis influence these associations., Methods: This prospective cohort study analyzed the data of UK Biobank participants who were diagnosed with cancer. The associations of fish oil and glucosamine consumption with mortality were analyzed using Cox proportional hazards models. Subgroup analyses were performed to assess the effects of Life Essential 8 [LE8] scores (a measure of cardiovascular health) and cancer prognosis (grouped according to the survival rates of specific cancer types) on the associations between supplement use and mortality., Results: This analysis included 14,920 participants (mean age = 59.9 years; 60.2% female). One third (34.1%) of the participants reported using fish oil, and one fifth (20.5%) reported using glucosamine. Over a median follow-up of 12.0 years, 2,708 all-cause deaths were registered. The use of fish oil was associated with reduced risks of all-cause mortality (adjusted hazard ratio [aHR] = 0.89, 95% Confidence Interval [CI] = 0.81-0.97) and cancer mortality (aHR = 0.89, 95% CI = 0.81-0.98). Similarly, glucosamine use was associated with reduced risks of all-cause mortality (aHR = 0.83, 95% CI = 0.74-0.92) and cancer mortality (aHR = 0.83, 95% CI = 0.74-0.93) in the fully adjusted model. Subgroup analyses revealed that the protective effects of fish oil and glucosamine against mortality risk were only observed in patients with LE8 scores lower than the mean score or a poor cancer prognosis. Additionally, the association between glucosamine use and a reduced risk of CVD-related mortality was only observed in patients with lower LE8 scores., Conclusions: This large cohort study identified the potential differential impact of LE8 scores and cancer prognosis on the associations of fish oil and glucosamine supplementation with survival in patients with cancer. This suggests the importance of considering these factors in future research on supplements and in the provision of personalized integrative cancer care., (© 2024. The Author(s).)

Background: To present findings from a retrospective study conducted by the Ultra-Rare Sarcoma Working Group on metastatic low-grade fibromyxoid sarcoma (LGFMS), sclerosing epithelioid fibrosarcoma (SEF), and hybrid (H)-LGFMS/SEF across 28 global centres., Methods: Patients treated at participating institutions from January 2000 to September 2022 were retrospectively selected. Diagnosis was confirmed by expert pathologists. Primary endpoint was progression-free survival (PFS-1) from metastasis detection to first progression or death. PFS-2 was calculated from therapy initiation., Results: A total of 101 patients were identified (32 LGFMS, 50 SEF, 19 H-LGFMS/SEF). Median (m) follow-up was 62.1 months. mPFS-1 was 28.7, 11.8, and 20.3 months for LGFMS, SEF, and H-LGFMS/SEF, respectively. mOS was 145.8, 41.9, and 113.5 months, respectively. Treatments included anthracycline-based chemotherapy, gemcitabine-based chemotherapy (G), pazopanib, trabectedin, others. mPFS-2 was: 20.1, 5.5, and 3.5 months in H-LGFMS/SEF, SEF, and LGFMS, respectively, with anthracyclines; 19.5, 7.7, and 6.9 months in LGFMS, SEF, and H-LGFMS/SEF, respectively, with pazopanib; 12.0, 9.7, and 3.1 months in H-LGFMS/SEF, LGFMS, and SEF, respectively. Occasional responses occurred with ifosfamide/oral cyclophosphamide, and prolonged stable disease with immune checkpoint inhibitors., Conclusions: In this series, the largest available, metastatic LGFMS, SEF, and H-LGFMS/SEF showed different courses. Systemic agents have modest efficacy, informing future trials of novel agents for these tumours., (Copyright © 2024 The Author(s). Published by Elsevier Ltd.. All rights reserved.)

Background: Soft tissue sarcomas (STS) are rare diseases typically arising from connective tissues in children and adults. However, chemotherapies involved in the treatment of STS may cause toxic side effects and multi-drug chemoresistance, making the treatment even more challenging. Histone deacetylase inhibitors (HDACi) are epigenetic agents which have shown anti-tumor effects as single agent as well as combination use with other drugs. Our project intends to prove the same effects in STS., Methods: Panobinostat (LBH589) plus doxorubicin was selected for investigations based on our previous research. Tumor xenografts were tried in an epithelioid sarcoma model to validate good synergy effects in vivo and a leiomyosarcoma model was used as a negative comparison group. Gene profile changes were studied afterwards. The possible pathway changes caused by HDACi were explored and validated by several assays., Results: Synergy effect of LBH589 plus doxorubicin was successfully validated in STS cell lines and an epithelioid sarcoma mice model. We tried to reduce the dose of doxorubicin to a lower level and found the drug combination can still inhibit tumor size in mice. Furthermore, gene profile changes caused by LBH589 was studied by RNA-Sequencing analysis. Results showed LBH589 can exert effects on a group of target genes which can regulate potential biological functions especially in the cell cycle pathway., 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 The Authors.

Neurotrophic tyrosine receptor kinase (NTRK) gene fusions are recurrent oncogenic drivers found in a variety of solid tumours, including lung cancer. Several tropomyosin receptor kinase (TRK) inhibitors have been developed to treat tumours with NTRK gene fusions. Larotrectinib and entrectinib are first-generation TRK inhibitors that have demonstrated efficacy in patients with TRK fusion lung cancers. Genomic testing is recommended for all patients with metastatic non-small cell lung cancer for optimal drug therapy selection. Multiple testing methods can be employed to identify NTRK gene fusions in the clinic and each has its own advantages and limitations. Among these assays, RNA-based next-generation sequencing (NGS) can be considered a gold standard for detecting NTRK gene fusions; however, several alternatives with minimally acceptable sensitivity and specificity are also available in areas where widespread access to NGS is unfeasible. This review highlights the importance of testing for NTRK gene fusions in lung cancer, ideally using the gold-standard method of RNA-based NGS, the various assays that are available, and treatment algorithms for patients., Competing Interests: Declaration of competing interest Support for attending meetings and/or travel: Sanofi.

This short report evaluated the accuracy and quality of information provided by ChatGPT regarding the use of complementary and integrative medicine for cancer. Using the QUality Evaluation Scoring Tool, a panel of 12 reviewers assessed ChatGPT's responses to 8 questions. The study found that ChatGPT provided moderate-quality responses that were relatively unbiased and not misleading. However, the chatbot's inability to reference specific scientific studies was a significant limitation. Patients with cancer should not rely on ChatGPT for clinical advice until further systematic validation. Future studies should examine how patients perceive ChatGPT's information and its impact on communication with health care professionals.

Background & Aims: The concurrent use of herbal and dietary supplements and conventional drugs can lead to interactions in patients with cancer, of which hepatotoxicity is one of the most concerning sequelae. This study examined the potential supplement-drug interactions involving the hepatic system, and their associations with documented liver diseases, among patients with cancer in a large population-based cohort in the UK Biobank., Methods: Participants diagnosed with cancer and had completed supplement-use assessment after diagnosis were included. Potentially interacting supplement-drug combinations that involved CYP enzymes or increased the risk of hepatotoxicity were identified from four tertiary databases. Liver diseases were identified using ICD-codes K70-77. Log-binomial regression was used to investigate the associations between potentially-interacting supplement-drug combinations and liver diseases documented (1) at any time, and (2) confined to only after the time of supplement-use assessment, adjusting for age, sex and pre-existing comorbidities., Results: This analysis included 30,239 participants (mean age = 60.0 years; 61.9% female). Over half (n = 17,698, 58.5%) reported the use of supplements after cancer diagnoses. Among supplements users, 36.9% (n = 6537/17,698) were on supplement-drug combinations with interacting potential involving the hepatic system. Patients taking supplements and drugs who had hepatic comorbidities were more likely to take potentially interacting pairs (adjusted risk ratio = 1.14, 95% CI = 1.06-1.23, p < 0.001). However, no significant association was observed between the use of these combinations and subsequent liver diseases (all p > 0.05)., Conclusion: Approximately one-third of the participants who had cancer and were supplement users had a risk of potential supplement-drug interactions that contribute to adverse liver effect. Healthcare professionals should communicate with patients with cancer, especially those with pre-existing liver diseases, about supplement use and proactively assess the clinical significance of potential interactions., Competing Interests: Declaration of competing interest The authors have no conflicts of interest to declare that are relevant to the content of this article., (Copyright © 2023 European Society for Clinical Nutrition and Metabolism.

Background: Selpercatinib, a highly selective potent and brain-penetrant RET inhibitor, was shown to have efficacy in patients with advanced RET fusion-positive non-small-cell lung cancer (NSCLC) in a nonrandomized phase 1-2 study., Methods: In a randomized phase 3 trial, we evaluated the efficacy and safety of first-line selpercatinib as compared with control treatment that consisted of platinum-based chemotherapy with or without pembrolizumab at the investigator's discretion. The primary end point was progression-free survival assessed by blinded independent central review in both the intention-to-treat-pembrolizumab population (i.e., patients whose physicians had planned to treat them with pembrolizumab in the event that they were assigned to the control group) and the overall intention-to-treat population. Crossover from the control group to the selpercatinib group was allowed if disease progression as assessed by blinded independent central review occurred during receipt of control treatment., Results: In total, 212 patients underwent randomization in the intention-to-treat-pembrolizumab population. At the time of the preplanned interim efficacy analysis, median progression-free survival was 24.8 months (95% confidence interval [CI], 16.9 to not estimable) with selpercatinib and 11.2 months (95% CI, 8.8 to 16.8) with control treatment (hazard ratio for progression or death, 0.46; 95% CI, 0.31 to 0.70; P<0.001). The percentage of patients with an objective response was 84% (95% CI, 76 to 90) with selpercatinib and 65% (95% CI, 54 to 75) with control treatment. The cause-specific hazard ratio for the time to progression affecting the central nervous system was 0.28 (95% CI, 0.12 to 0.68). Efficacy results in the overall intention-to-treat population (261 patients) were similar to those in the intention-to-treat-pembrolizumab population. The adverse events that occurred with selpercatinib and control treatment were consistent with those previously reported., Conclusions: Treatment with selpercatinib led to significantly longer progression-free survival than platinum-based chemotherapy with or without pembrolizumab among patients with advanced RET fusion-positive NSCLC.

Epidermal growth factor receptor ( EGFR ) T790M mutations drive resistance in 50% of patients with advanced non-small cell lung cancer (NSCLC) who progress on first/second generation (1G/2G) EGFR tyrosine kinase inhibitors (TKIs) and are sensitive to Osimertinib. Tissue sampling is the gold-standard modality of T790M testing, but it is invasive. We evaluated the efficacy of Osimertinib in patients with EGFR mutant NSCLC and T790M in circulating tumour DNA (ctDNA). PLASMA is a prospective, open-label, multicentre single-arm Phase II study. Patients with advanced NSCLC harbouring sensitizing EGFR and T790M mutations in plasma at progression from ≥one 1G/2G TKI were treated with 80 mg of Osimertinib daily until progression. The primary endpoint was the objective response rate (ORR); the secondary endpoints included progression-free survival (PFS), overall survival (OS), disease control rate (DCR) and toxicities. Plasma next-generation sequencing was performed to determine Osimertinib resistance mechanisms and assess serial ctDNA. A total of 110 patients from eight centres in five countries were enrolled from 2017 to 2019. The median follow-up duration was 2.64 (IQR 2.44-3.12) years. The ORR was 50.9% (95% CI 41.2-60.6) and the DCR was 84.5% (95% CI 76.4-90.7). Median PFS was 7.4 (95% CI 6.0-9.3) months; median OS was 1.63 (95% CI 1.35-2.16) years. Of all of the patients, 76% had treatment-related adverse events (TRAEs), most commonly paronychia (22.7%); 11% experienced ≥ Grade 3 TRAEs. The ctDNA baseline load and dynamics were prognostic. Osimertinib is active in NSCLC harbouring sensitizing EGFR and T790M mutations in ctDNA testing post 1G/2G TKIs.

Purpose: Adolescent and young adult (AYA) patients with cancer often experience unique physical and psychosocial complications. They may turn to traditional, complementary and integrative medicines (TCIM) to address these concerns. To examine the pattern of TCIM use among AYA patients with cancer and explored their preferences regarding TCIM education., Methods: Between August 2021 and December 2022, 246 patients diagnosed with cancer between 15 and 39 years old were recruited from hospitals in Hong Kong. They completed a structured questionnaire on TCIM use, symptom burden, psychological status and preference on education content. Multivariable logistic regression was used to identify predictors of TCIM use, adjusting for age and sex., Results: Overall, 60.2% reported TCIM use, most commonly vitamins (24.0%) and Chinese herbal medicine (22.0%). The most common reasons for using TCIM were to improve general health (70.9%) and manage chronic symptoms (33.1%). Among patients on active treatment, TCIM users tend to report higher anxiety symptoms (aOR = 1.13, 95% CI = 1.02-1.27). TCIM users who were post-treatment were more likely to have chronic comorbidities (aOR = 3.54, 95% CI = 1.29-11.5). AYA patients indicated that they would like TCIM information to address specific needs, particularly fatigue (53.7%) and psychological problems (54.1%)., Conclusions: The use of TCIM is common among AYA patients with cancer, especially among patients with high symptom burdens. A tailored education programme should be provided based on patients' preferences and needs. Healthcare professionals including oncologists and oncology nurses should communicate with AYA patients about TCIM use and address their needs by making evidence-based referrals/recommendations based on treatment status and symptom burden., 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 Ltd.

Introduction: Next-generation sequencing (NGS) diagnostics have shown clinical utility in predicting survival benefits in patients with certain cancer types who are undergoing targeted drug therapies. Currently, there are no guidelines or recommendations for the use of NGS in patients with metastatic cancer from an Asian perspective. In this article, we present the Asia-Pacific Oncology Drug Development Consortium (APODDC) recommendations for the clinical use of NGS in metastatic cancers., Methods: The APODDC set up a group of experts in the field of clinical cancer genomics to (i) understand the current NGS landscape for metastatic cancers in the Asia-Pacific (APAC) region; (ii) discuss key challenges in the adoption of NGS testing in clinical practice; and (iii) adapt/modify the European Society for Medical Oncology guidelines for local use. Nine cancer types [breast cancer (BC), gastric cancer (GC), nasopharyngeal cancer (NPC), ovarian cancer (OC), prostate cancer, lung cancer, and colorectal cancer (CRC) as well as cholangiocarcinoma and hepatocellular carcinoma (HCC)] were identified, and the applicability of NGS was evaluated in daily practice and/or clinical research. Asian ethnicity, accessibility of NGS testing, reimbursement, and socioeconomic and local practice characteristics were taken into consideration., Results: The APODDC recommends NGS testing in metastatic non-small-cell lung cancer (NSCLC). Routine NGS testing is not recommended in metastatic BC, GC, and NPC as well as cholangiocarcinoma and HCC. The group suggested that patients with epithelial OC may be offered germline and/or somatic genetic testing for BReast CAncer gene 1 (BRCA1), BRCA2, and other OC susceptibility genes. Access to poly (ADP-ribose) polymerase inhibitors is required for NGS to be of clinical utility in prostate cancer. Allele-specific PCR or a small-panel multiplex-gene NGS was suggested to identify key alterations in CRC., Conclusion: This document offers practical guidance on the clinical utility of NGS in specific cancer indications from an Asian perspective., (Copyright © 2023 The Authors.

Retroperitoneal soft tissue sarcomas mainly consist histologically of liposarcomas and leiomyosarcomas. For the liposarcoma subgroup, the local relapse rate seems to determine patients' overall prognosis. In contrast, leiomyosarcoma patients are challenged by the development of metastatic disease; therefore, effective systemic therapies are the cornerstone to improve patients' outcome. No doubt, the limited number of active regimens currently available makes the treatment of patients with locally advanced and/or metastatic disease challenging and results in the overall poor prognosis of this population. In this European Journal of Surgical Oncology Educational Special Issue from the Transatlantic Australasian RetroPeritoneal Sarcoma Working Group (TARPSWG), we aim to summarize state-of-the-art systemic treatments for patients with retroperitoneal sarcomas with a focus on the locally advanced and metastatic disease setting including conventional standard chemotherapies as well as new innovative treatment approaches in order to identify current unmet medical needs guiding the sarcoma community to initiate appropriate translational research projects and design innovative clinical trials., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest., (Copyright © 2021 Elsevier Ltd, BASO ~ The Association for Cancer Surgery, and the European Society of Surgical Oncology.

Background: Next-generation sequencing comprehensive genomic panels (NGS CGPs) have enabled the delivery of tailor-made therapeutic approaches to improve survival outcomes in patients with cancer. Within the China Greater Bay Area (GBA), territorial differences in clinical practices and health care systems and strengthening collaboration warrant a regional consensus to consolidate the development and integration of precision oncology (PO). Therefore, the Precision Oncology Working Group (POWG) formulated standardized principles for the clinical application of molecular profiling, interpretation of genomic alterations, and alignment of actionable mutations with sequence-directed therapy to deliver clinical services of excellence and evidence-based care to patients with cancer in the China GBA., Methods: Thirty experts used a modified Delphi method. The evidence extracted to support the statements was graded according to the GRADE system and reported according to the Revised Standards for Quality Improvement Reporting Excellence guidelines, version 2.0., Results: The POWG reached consensus in six key statements: harmonization of reporting and quality assurance of NGS; molecular tumor board and clinical decision support systems for PO; education and training; research and real-world data collection, patient engagement, regulations, and financial reimbursement of PO treatment strategies; and clinical recommendations and implementation of PO in clinical practice., Conclusion: POWG consensus statements standardize the clinical application of NGS CGPs, streamline the interpretation of clinically significant genomic alterations, and align actionable mutations with sequence-directed therapies. The POWG consensus statements may harmonize the utility and delivery of PO in China's GBA.

Background: The integration of next-generation sequencing (NGS) comprehensive gene profiling (CGP) into clinical practice is playing an increasingly important role in oncology. Therefore, the HKU-HKSH Multi-disciplinary Molecular Tumour Board (MTB) was established to advance precision oncology in Hong Kong. A multicenter retrospective study investigated the feasibility of the HKU-HKSH MTB in determining genome-guided therapy for treatment-refractory solid cancers in Hong Kong., Methods: Patients who were presented at the HKU-HKSH MTB between August 2018 and June 2022 were included in this study. The primary study endpoints were the proportion of patients who receive MTB-guided therapy based on genomic analysis and overall survival (OS). Secondary endpoints included the proportion of patients with actionable genomic alterations, objective response rate (ORR), and disease control rate (DCR). The Kaplan-Meier method was used in the survival analyses, and hazard ratios were calculated using univariate Cox regression., Findings: 122 patients were reviewed at the HKU-HKSH MTB, and 63% (n = 77) adopted treatment per the MTB recommendations. These patients achieved a significantly longer median OS than those who did not receive MTB-guided therapy (12.7 months vs. 5.2 months, P = 0.0073). Their ORR and DCR were 29% and 65%, respectively., Interpretation: Our study demonstrated that among patients with heavily pre-treated advanced solid cancers, MTB-guided treatment could positively impact survival outcomes, thus illustrating the applicability of NGS CGPs in real-world clinical practice., Funding: The study was supported by the Li Shu Pui Medical Foundation. Dr Aya El Helali was supported by the Li Shu Pui Medical Foundation Fellowship grant from the Li Shu Pui Medical Foundation. Funders had no role in study design, data collection, data analysis, interpretation, or writing of the report., Competing Interests: All authors declare no competing interests., (© 2023 The Authors.)

Background: Patients with cancer are increasingly using forums and social media platforms to access health information and share their experiences, particularly in the use of traditional, complementary, and integrative medicine (TCIM). Despite the popularity of TCIM among patients with cancer, few related studies have used data from these web-based sources to explore the use of TCIM among patients with cancer., Objective: This study leveraged multiple forums and social media platforms to explore patients' use, interest, and perception of TCIM for cancer care., Methods: Posts (in English) related to TCIM were collected from Facebook, Twitter, Reddit, and 16 health forums from inception until February 2022. Both manual assessments and natural language processing were performed. Descriptive analyses were performed to explore the most commonly discussed TCIM modalities for each symptom and cancer type. Sentiment analyses were performed to measure the polarity of each post or comment, and themes were identified from posts with positive and negative sentiments. TCIM modalities that are emerging or recommended in the guidelines were identified a priori. Exploratory topic-modeling analyses with latent Dirichlet allocation were conducted to investigate the patients' perceptions of these modalities., Results: Among the 1,620,755 posts available, cancer-related symptoms, such as pain (10/10, 100% cancer types), anxiety and depression (9/10, 90%), and poor sleep (9/10, 90%), were commonly discussed. Cannabis was among the most frequently discussed TCIM modalities for pain in 7 (70%) out of 10 cancer types, as well as nausea and vomiting, loss of appetite, anxiety and depression, and poor sleep. A total of 7 positive and 7 negative themes were also identified. The positive themes included TCIM, making symptoms manageable, and reducing the need for medication and their side effects. The belief that TCIM and conventional treatments were not mutually exclusive and intolerance to conventional treatment may facilitate TCIM use. Conversely, TCIM was viewed as leading to patients' refusal of conventional treatment or delays in diagnosis and treatment. Doctors' ignorance regarding TCIM and the lack of information provided about TCIM may be barriers to its use. Exploratory analyses showed that TCIM recommendations were well discussed among patients; however, these modalities were also used for many other indications. Other notable topics included concerns about the legalization of cannabis, acupressure techniques, and positive experiences of meditation., Conclusions: Using machine learning techniques, social media and health forums provide a valuable resource for patient-generated data regarding the pattern of use and patients' perceptions of TCIM. Such information will help clarify patients' needs and concerns and provide directions for research on integrating TCIM into cancer care. Our results also suggest that effective communication about TCIM should be achieved and that doctors should be more open-minded to actively discuss TCIM use with their patients., (©Chun Sing Lam, Keary Zhou, Herbert Ho-Fung Loong, Vincent Chi-Ho Chung, Chun-Kit Ngan, Yin Ting Cheung.

Aims: The protracted COVID-19 pandemic has overwhelmed health systems globally, including many aspects of cancer control. This has underscored the multidimensional nature of cancer control, which requires a more comprehensive approach involving taking a wider perspective of health systems. Here, we investigated aspects of health system resilience in maintaining cancer services globally during the COVID-19 pandemic. This will allow for health systems to be resilient to different types of system stressors/shocks in the future, to allow cancer care to be maintained optimally., Materials and Methods: Using the World Health Organization health system framework (capturing aspects of service delivery, health workforce, information, medical products, vaccines and technologies, financing and governance and leadership), we carried out a comparative analysis of the impact of COVID-19 and the synthesis of the findings in responses in cancer care in 10 countries/jurisdictions across four continents comprising a wide diversity of health systems, geographical regions and socioeconomic status (China, Colombia, Egypt, Hong Kong SAR, Indonesia, India, Singapore, Sri Lanka, UK and Zambia). A combination of literature and document reviews and interviews with experts was used., Results: Our study revealed that: (i) underlying weaknesses of health systems before the pandemic were exacerbated by the pandemic (e.g. economic issues in low- and middle-income countries led to greater shortage of medication and resource constraints compounded by inadequacies of public financing and issues of engagement with stakeholders and leadership/governance); (ii) no universal adaptive strategies were applicable to all the systems, highlighting the need for health systems to design emergency plans based on local context; (iii) despite the many differences between health systems, common issues were identified, such as the lack of contingency plan for pandemics, inadequate financial policies for cancer patients and lack of evidence-based approaches for competing priorities of cancer care/pandemic control., Conclusion: We identified four key points/recommendations to enhance the resilient capacity of cancer care during the COVID-19 pandemic and other system stressors: (i) effective pandemic control approaches in general are essential to maintain the continuity of cancer care during the emergency health crises; (ii) strong health systems (with sufficient cancer care resources, e.g. health workforce, and universal health coverage) are fundamental to maintain quality care; (iii) the ability to develop response strategies and adapt to evolving evidence/circumstances is critical for health system resilience (including introducing systematic, consistent and evidence-based changes, national support and guidance in policy development and implementation); (iv) preparedness and contingency plans for future public health emergencies, engaging the whole of society, to achieve health system resilience for future crises and to transform healthcare delivery beyond the pandemic., (Copyright © 2023.

Purpose: Despite the increasing popularity of supplement use among the cancer community, the current evidence on its effect on mortality in large studies is inconclusive. This study examined the association of dietary supplement use with mortality risk in a large population-based cohort., Methods: This prospective cohort study analyzed data from the UK Biobank on participants who were diagnosed with cancer before July 31, 2019 and self-reported whether they had regular intake of dietary supplements (vitamins, minerals, or non-vitamin non-mineral [NVNM] supplements) after cancer diagnosis. The associations between the use of supplements with mortality were analyzed using Cox proportional hazards models, adjusting for confounders (sociodemographic factors, lifestyle and comorbidities)., Results: This analysis included 30,239 participants (mean age: 60.0 years; 61.9% female). Over half (57.8%) were supplement users. At a median follow-up of 11.9 years, 5577 all-cause deaths were registered. A marginal protective effect of supplement use on the risk of all-cause (adjusted hazard ratio [aHR] = 0.95, 95% CI = 0.90-0.99) and cancer (aHR = 0.89, 95% CI = 0.83-0.95) mortality were found, but not the risk of mortality due to other causes. In subgroup analyses, only NVNM dietary supplements were significantly associated with a lower risk of all-cause mortality (aHR = 0.88, 95% CI = 0.83-0.93). Both vitamins (aHR = 0.93, 95% CI = 0.87-0.99) and NVNM dietary supplements (aHR = 0.88, 95% CI = 0.82-0.94) were associated with a modest decrease in cancer mortality which were marginally significant., Conclusions: This is one of the largest cohort studies that identified the associations of dietary supplements with survival in the cancer population. However, the associations are small and should be interpreted cautiously due to the variations among different supplements and the small effect size. Future studies should investigate the effect of individual supplements, particularly NVNM supplements, on improving other cancer-related outcomes., (© 2022.

Importance: New dosing options for immune checkpoint inhibitors have recently been approved by the US Food and Drug Administration (FDA), including fixed dosing with extended intervals. Although the dose intensity appears the same, there is expected to be some waste with extended-interval dosing, as some drug remains in the bloodstream once a decision to stop treatment is made. The economic impact of extended-interval fixed dosing is unknown compared with standard-interval fixed dosing., Objective: To analyze the potential health care costs of using extended-interval fixed dosing instead of standard-interval fixed dosing., Design, Setting, and Participants: This economic evaluation used a pharmacoeconomic model to simulate 2 cohorts of patients with platinum-resistant metastatic urothelial cancer receiving pembrolizumab as second-line therapy at different dosing intervals using 2020 pricing data. Data were analyzed from 2020 to 2022., Exposures: The simulated patients received FDA-approved regimens of either 200 mg every 3 weeks or 400 mg every 6 weeks., Main Outcomes and Measures: The progression-free survival curve from the KEYNOTE-045 trial was used to estimate treatment duration. Drug, imaging, and administration costs were included in analyses. Sensitivity analyses were performed to assess how different imaging frequencies would affect the model results. The potential overall costs of using the 2 different dosing strategies were assessed. The base case was set in the US, while sensitivity analyses were set in several other countries., Results: In the base case analysis, dosing every 6 weeks instead of every 3 weeks resulted in an estimated 8.9% increase in pembrolizumab costs for the health care payer. Accounting for a decrease in infusion costs would result in an estimated net additional cost of $7483 per patient in the US (7.9% cost increase). In the US, this would amount to an increase of approximately $28 million annually for health care payers. Similar percentages in cost estimate increases were found for health care payers around the world, such as in Israel, where the net additional cost would be $5491 per patient., Conclusions and Relevance: This economic evaluation assessed and quantified the potential increased costs related to extended-interval fixed dosing of pembrolizumab. The model method could be applied to other diseases and other drugs for which there has been a movement toward extended-interval dosing. Results may differ in other diseases owing to differing disease courses and patient profiles.

Background: The effect of adding local ablative radiotherapy on oligo-progression while continuing EGFR-TKIs in advanced non-small cell Lung cancer (NSCLC) patients is to be determined., Methods: Outcomes of patients with stage IV NSCLC harboring EGFR-activating mutations having ≤5 sites of oligo-progression while on EGFR-TKIs and given one to eight fractions of local ablative radiotherapy (LAR) were reviewed from 2012 to 2019. The time of starting first-line EGFR-TKIs to LAR is defined as progression-free survival 1 (PFS1; > one line of prior treatment allowed). The primary endpoint was PFS from LAR to further progression that led to stop of EGFR-TKIs (PFS2). The secondary endpoint was overall survival from LAR (OS). Factors affecting PFS2 and OS were analyzed with Cox regression., Results: There were total 55 eligible patients. The median follow-up time was 13.3 months. Majority (89%) had sensitive mutations (exon 19 deletion and exon 21 L858R mutation). Total number of lesions treated were 75, including lung (n = 45), bone (n = 15), cervical lymph node (n = 1), adrenal (n = 1), and brain (n = 13). The median PFS2 was 6.9 months. The median OS was 25.1 months. On multivariable analysis, it was found that EGFR mutation type (exon 19 deletion / exon 21 L858R mutation vs. other rarer mutations), time from diagnosis to LAR within 70 days, and fewer lines of prior TKIs (1 or 2 vs. 3) had favorable effect on PFS2 (p = 0.006/0.00003; 0.046; 0.001/0.005, respectively)., Conclusion: LAR is a noninvasive and effective modality in treatment of oligo-progressive diseases for patients with EGFR mutations positive NSCLC while on EGFR-TKIs., (© 2022 John Wiley & Sons Australia, Ltd.)

Objective: To investigate whether Adjunctive PD-1 inhibitors have improved clinical outcomes compared to chemotherapy alone in platinum-pretreated and platinum-naive recurrent or metastatic nasopharyngeal carcinoma (R/M NPCA)., Methods: The study involved a literature search from PubMed, Cochrane CENTRAL, and Google Scholar for randomized clinical trials (RCTs) on the use of PD-1 inhibitors versus chemotherapy alone in patients with R/M NPCA. Bias was assessed using Cochrane collaboration's risk of bias tool. Overall Survival (OS) was examined as the primary endpoint. Secondary endpoints were Progression-Free Survival (PFS), Objective Response Rate, Disease Control Rate (DCR), Duration of Response, and Serious/Grade ⩾3 Adverse Events. Outcomes were measured with either Mean Difference, Risk ratio (RR), or Hazard ratios (HRs) at 95% confidence interval., Results: Four RCTs were included in the meta-analysis and systematic review. OS for the monotherapy subgroup was a HR of 0.87 [0.67, 1.13] ( p  = 0.30) while the combination subgroup had 0.64 [0.45, 0.90] ( p  = 0.01). The monotherapy subgroup exhibited significantly worse outcomes in PFS (HR 1.31 [1.01, 1.68]) ( p  = 0.04) and DCR (RR 1.52 [1.12, 2.05]) ( p  = 0.007) but no significant difference in other outcomes. For combination therapy, a statistically significant benefit can be seen in all outcomes except DCR (RR 0.62 [0.38, 1.01]) ( p  = 0.06) which was a non-significant benefit favoring PD-1 inhibitors., Conclusion: Combination PD-1 inhibitor + chemotherapy followed by maintenance PD-1 inhibitor therapy is superior to chemotherapy alone in the first-line treatment of R/M NPCA, implying a potential benefit with the use of PD-1 inhibitors + chemotherapy with maintenance PD-1 inhibitors as first-line in R/M NPCA compared to standard chemotherapy alone., Competing Interests: The authors declare that there is no conflict of interest., (© The Author(s), 2022.)

Purpose: Act.In.Sarc (NCT02379845) demonstrated that the first-in-class radioenhancer NBTXR3, activated by preoperative radiation therapy (RT), doubled the rate of pathologic complete response after resection compared with preoperative RT alone in adult patients with locally advanced soft tissue sarcoma of the extremity or trunk wall (16.1% vs 7.9%, P = .045), and more patients achieved R0 resections (77.0% vs 64.0%, P = .042). These are the toxicity and health-related quality of life (HRQoL) results., Methods and Materials: Act.In.Sarc randomized eligible patients 1:1 to either NBTXR3 (single intratumoral injection, volume equivalent to 10% of baseline tumor volume, at 53.3 g/L) activated by external-beam RT (arm A) or external-beam RT alone (arm B) (50 Gy in 25 fractions), followed by surgery in both arms. Here, we report the safety analyses in the all-treated population with a long-term follow-up of at least 2 years, and HRQoL in the intention-to-treat full analysis set., Results: During the on-treatment period, serious adverse events (SAEs) of all grades related to NBTXR3 occurred in 10.1% (9/89) of patients (arm A), and SAEs related to RT occurred in 5.6% (5/89) (arm A) versus 5.6% (5/90) (arm B); postsurgery hospitalization owing to SAEs occurred in 15.7% (14/89) (arm A) versus 24.4% (22/90) (arm B). During the follow-up period, posttreatment SAEs (regardless of relationship) occurred in 13.5% (12/89) (arm A) versus 24.4% (22/90) (arm B). NBTXR3 did not negatively affect HRQoL; during the follow-up period, there was an improvement in most mean Toronto extremity salvage, EuroQoL 5-dimension (EQ-5D), EQ5D02-EQ visual analog scale, reintegration to normal living index, and musculoskeletal tumor rating scale scores., Conclusions: NBTXR3 did not negatively affect safety or HRQoL. Long-term safety results reinforce the favorable benefit-risk ratio of NBTXR3 plus RT., (Copyright © 2022 The Author(s). Published by Elsevier Inc. All rights reserved.)

Advanced genomic techniques have now been incorporated into diagnostic practice in neuro-oncology in the literature. However, these assays are expensive and time-consuming and demand bioinformatics expertise for data interpretation. In contrast, single-gene tests can be run much more cheaply, with a short turnaround time, and are available in general pathology laboratories. The objective of this study was to establish a molecular grading scheme for adult gliomas using combinations of commonly available single-gene tests. We retrospectively evaluated molecular diagnostic data of 1,275 cases of adult diffuse gliomas from three institutions where we were testing for IDH1/2 mutation, TERTp mutation, 1p19q codeletion, EGFR amplification, 10q deletion, BRAF V600E, and H3 mutations liberally in our regular diagnostic workup. We found that a molecular grading scheme of Group 1 (1p19q codeleted, IDH mutant), Group 2 (IDH mutant, 1p19q non-deleted, TERT mutant), Group 3 (IDH mutant, 1p19q non-deleted, TERT wild type), Group 4 (IDH wild type, BRAF mutant), Group 5 (IDH wild type, BRAF wild type and not possessing the criteria of Group 6), and Group 6 (IDH wild type, and any one of TERT mutant, EGFR amplification, 10q deletion, or H3 mutant) could significantly stratify this large cohort of gliomas for risk. A total of 1,028 (80.6%) cases were thus classifiable with sufficient molecular data. There were 270 cases of molecular Group 1, 59 cases of molecular Group 2, 248 cases of molecular Group 3, 27 cases of molecular Group 4, 117 cases of molecular Group 5, and 307 cases of molecular Group 6. The molecular groups were independent prognosticators by multivariate analyses and in specific instances, superseded conventional histological grades. We were also able to validate the usefulness of the Groups with a cohort retrieved from The Cancer Genome Atlas (TCGA) where similar molecular tests were liberally available. We conclude that a single-gene molecular stratification system, useful for fine prognostication, is feasible and can be adopted by a general pathology laboratory., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Chan, Shi, Li, Wang, Chen, Chung, Chan, Poon, Loong, Liu, Zhang, Mao and Ng.)

Background: The number of randomized trials of agents targeting oncogene-addicted tumors has surged in the past 10 years. Using a meta-analysis, we explored whether improvements in objective response rate (ORR) in comparative trials using targeted agents could serve as a potential surrogate endpoint for improvements in progression-free survival (PFS) or overall survival (OS) in populations with oncogene-addicted cancer., Patients and Methods: Using commercial text mining software I2E, we searched ClinicalTrials.gov and MEDLINE databases for randomized, phase III trials based on prospectively defined criteria, including (i) use of agents targeting EGFR activating mutations, ALK rearrangements, BRAF V600E or V600K mutations, and BCR-ABL fusion protein; (ii) molecularly enriched trial population or subpopulation; (iii) control arm only randomized to chemo/cytotoxic therapy. Correlative analyses were performed using ORR, OS, and PFS data from trials that met these criteria., Results: A total of 62 trials were identified; 15 met all of the prespecified criteria. The ORR effect size (both the difference in ORR between arms and the log odds ratio) and log PFS hazard ratio were strongly correlated: -0.78 (P = 0.0007) for the ORR difference model; -0.74 (P = 0.0017) for the log odds ratio model. ORR effect size was positively correlated with the log OS hazard ratio, but more weakly: -0.67 (P = 0.013) for the ORR difference model and -0.58 (P = 0.036) for the log odds ratio model. Analysis of the treatment effects between OS and PFS found no correlation., Conclusions: These analyses identified a strong correlation between treatment effects on ORR and PFS in randomized clinical trials investigating agents targeting oncogene-driven cancers. A weaker correlation was observed between ORR and OS. These meta-analysis results support the use of a high ORR forming the basis of an initial regulatory approval in biomarker-driven studies., Competing Interests: Disclosure BJS reports personal fees from Loxo Oncology, during the conduct of the study; personal fees from AstraZeneca, Novartis, Roche/Genentech, Bristol Myers Squibb, Merck, Gritstone Oncology, Amgen, Sanofi/Regeneron, and grants and personal fees from Pfizer, all outside the submitted work.

Introduction: Upfront next-generation sequencing (NGS) in patients with metastatic NSCLC has been associated with cost savings and shorter time-to-test results in the United States. Nevertheless, this may not apply in jurisdictions where the prevalence of patients with actionable mutations, cost of health care, and reimbursement models differ., Methods: A decision analytical model was built to compare sequential, panel, exclusionary, and upfront NGS testing in patients with metastatic NSCLC in Hong Kong. In sequential and panel testing, patients were tested for genomic alterations (GAs) with treatment followed by sequential or NGS. In exclusionary testing, EGFR and ALK were tested first, followed by NGS. For each modality, the mutation identified, time to receive testing results, and costs (2020 U.S. dollars) were estimated., Results: Exclusionary testing required the shortest time-to-results (1.6 wk) and was most cost saving. In the scenario where all patients used exclusionary testing, a cost saving of $4.6 million was expected relative to current practice, with 90.7% of actionable and 46.5% of nonactionable GAs detected; when all patients used NGS, it would be $2.9 million more expensive with a 100% GA detection rate. Results were sensitive to testing costs and the proportion of patients that continued testing., Conclusions: Exclusionary testing is the best option in terms of cost and time-to-results in Hong Kong. This finding may be applicable for other Asian countries; however, exclusionary testing does not capture all possible GAs. As more GAs become actionable and the cost of NGS declines, NGS may become a cost-saving option., (© 2022 The Authors.)

Purpose: We report the intracranial efficacy of selpercatinib, a highly potent and selective RET inhibitor, approved in the United States for RET fusion-positive non-small cell lung cancers (NSCLC)., Patients and Methods: In the global phase 1/2 LIBRETTO-001 trial (NCT03157128) in advanced RET -altered solid tumors, selpercatinib was dosed orally (160 mg twice every day) in 28-day cycles. Patients with baseline intracranial metastases had MRI/CT scans every 8 weeks for 1 year (12 weeks thereafter). In this pre-planned analysis of patients with RET fusion-positive NSCLC with baseline intracranial metastases, the primary endpoint was independently assessed intracranial objective response rate (ORR) per RECIST 1.1. Secondary endpoints included intracranial disease control rate, intracranial duration of response, and intracranial progression-free survival (PFS) independently reviewed., Results: Eighty patients with NSCLC had brain metastases at baseline. Patients were heavily pretreated (median = 2 systemic therapies, range = 0-10); 56% of patients received ≥1 course of intracranial radiation (14% whole brain radiotherapy, 45% stereotactic radiosurgery). Among 22 patients with measurable intracranial disease at baseline, intracranial ORR was 82% [95% confidence interval (CI), 60-95], including 23% with complete responses. Among all intracranial responders (measurable and nonmeasurable, n = 38), median duration of intracranial response was not reached (95% CI, 9.3-NE) at a median duration of follow-up of 9.5 months (IQR = 5.7, 12.0). At 12 months, 55% of intracranial responses were ongoing. In all 80 patients, median intracranial PFS was 13.7 months (95% CI, 10.9-NE) at a median duration of follow-up of 11.0 months (IQR = 7.4, 16.5). No new safety signals were revealed in patients with brain metastases compared with the full NSCLC trial population., Conclusions: Selpercatinib has robust and durable intracranial efficacy in patients with RET fusion-positive NSCLC., (©2021 The Authors; Published by the American Association for Cancer Research.)

Aim: The significance and prioritization of early phase oncology trial continuation during a global pandemic is unknown. This study reported the outcomes, multiple challenges, and broad recommendations associated with the impact of the novel coronavirus disease 2019 (COVID-19) on oncology early phase 1 trials-and on drug development in Asia-based on the experiences and perspectives of Asian oncology phase 1 centers., Methods: Between March and April 2020 during the initial period of outbreak, the impact of COVID-19 across oncology phase 1 sites in five Asian countries-China (Hong Kong), Japan, South Korea, Taiwan, and Singapore-was retrospectively analyzed., Results: There was no trial termination or treatment discontinuation in all five countries. Although the most common impact was new patient enrollment being placed on hold, which was based on pharmaceutical sponsors' decision-making, the situation varied per site. Most sites had no restrictions in place that would limit their ability to fully comply with the requirements of conducting the early phase studies. The number of protocol deviations during the pandemic was largely dependent on domestic transportation status during the outbreak rather than the ability of the clinical trial centers., Conclusion: Determining the risk to benefits ratio of patients with cancer who are enrolled in early phase 1 clinical trials under the unusual circumstances of a global pandemic is important. Specific guidance or guidelines on the conduct of early phase 1 clinical trials during public health emergencies that are based on the recent lessons learned is urgently required., (© 2021 The Authors.

Emerging efficacy data have led to the emergency use authorization or approval of COVID-19 vaccines in several countries worldwide. Most trials of COVID-19 vaccines excluded patients with active malignancies, and thus data on the safety, tolerability and efficacy of the vaccines in patients with cancer are currently limited. Given the risk posed by the COVID-19 pandemic, decisions regarding the use of vaccines against COVID-19 in patients participating in trials of investigational anticancer therapies need to be addressed promptly. Patients should not have to choose between enrolling on oncology clinical trials and receiving a COVID-19 vaccine. Clinical trial sponsors, investigators and treating physicians need operational guidance on COVID-19 vaccination for patients with cancer who are currently enrolled or might seek to enrol in clinical trials. Considering the high morbidity and mortality from COVID-19 in patients with cancer, the benefits of vaccination are likely to far outweigh the risks of vaccine-related adverse events. Herein, we provide operational COVID-19 vaccine guidance for patients participating in oncology clinical trials. In our perspective, continued quality oncological care requires that patients with cancer, including those involved in trials, be prioritized for COVID-19 vaccination, which should not affect trial eligibility.

Angiosarcoma (AS) is a rare disease with a dismal prognosis. The treatment landscape and prognostic factors for advanced AS, including locally advanced, unresectable, and metastatic disease remain elusive. The Asian Sarcoma Consortium is an international collaborative effort to understand the sarcoma treatment landscape in Asia. We undertook a retrospective chart review of AS patients seen in 8 sarcoma academic centers across Asia. Patients with complete clinical, treatment, and follow-up data were enrolled. Overall, 276 advanced AS patients were included into this study; 84 (30%) of the patients had metachronous metastatic AS. The median age was 67 y; primary sites of AS was cutaneous in 55% and visceral in 45% of patients. In total, 143 (52%) patients received at least 1 line of systemic chemotherapy. The most common first-line chemotherapy regimen used was paclitaxel (47.6%) followed by liposomal doxorubicin (19.6%). The median overall survival (OS) was 7.8 mo. Significant prognostic factors for OS included age > 65 (hazard ratio (HR) 1.54, P = .006), male gender (HR 1.39, P = .02), and a cutaneous primary AS site (HR 0.63, P = .004). The median progression-free survival (PFS) for first-line chemotherapy was 3.4 mo. PFS for single vs combination or paclitaxel vs liposomal doxorubicin chemotherapy regimens were comparable. This study provides an insight into the treatment patterns and prognostic factors of advanced AS patients in Asia. Prognosis of advanced AS remains poor. Data from this study serve as a benchmark for future clinical study design., (© 2021 The Authors.

Selpercatinib, a novel, highly selective and potent, inhibitor of RET , demonstrated clinically meaningful antitumor activity with manageable toxicity in heavily pretreated and treatment-naive RET fusion-positive non-small-cell lung cancer patients in a Phase I/II clinical trial. LIBRETTO-431 (NCT04194944) is a randomized, global, multicenter, open-label, Phase III trial, evaluating selpercatinib versus carboplatin or cisplatin and pemetrexed chemotherapy with or without pembrolizumab in treatment-naive patients with locally advanced/metastatic RET fusion-positive nonsquamous non-small-cell lung cancer. The primary end point is progression-free survival by independent review. Key secondary end points include overall survival, response rate, duration of response and progression-free survival. Clinical trial registration: NCT04194944 (ClinicalTrials.gov).

Introduction: Lower-dose ceritinib (450 mg) once-daily with food was approved in 2018 in Hong Kong (HK) for first-line treatment of patients with anaplastic lymphoma kinase-positive (ALK +) advanced non-small cell lung cancer (NSCLC). This study examined the cost-effectiveness of ceritinib vs. crizotinib in the first-line treatment of ALK + NSCLC from a HK healthcare service provider's or government's perspective., Methods: Costs and effectiveness of first-line ceritinib vs. crizotinib over a 20-year time horizon was evaluated using a partitioned survival model with three health states (stable disease, progressed disease, and death). The efficacy data for ceritinib were obtained from a phase 3 trial comparing ceritinib with chemotherapy for advanced non-small cell lung cancer (ASCEND-4) and extrapolated using parametric survival models. Long-term survival associated with crizotinib were estimated using hazard ratio of crizotinib vs. ceritinib obtained from matching-adjusted indirect comparison based on ASCEND-4 and PROFILE 1014 trials. Drug acquisition, administration, adverse events costs, and medical costs associated with each health state were obtained from public sources and converted to 2018 US Dollars. Incremental costs per quality-adjusted-life-year (QALY) and life-year (LY) gained were estimated for ceritinib vs. crizotinib., Results: The base case results showed that ceritinib was associated with 3.22 QALYs, 4.51 LYs, and total costs of $157,581 over 20 years. Patients receiving crizotinib had 2.68 QALYs, 3.85 LYs, and $150,424 total costs over the same time horizon. The incremental cost per QALY gained for ceritinib vs crizotinib was $13,343. Results were robust to deterministic sensitivity analyses in most scenarios., Conclusion: Ceritinib offers a cost-effective option compared to crizotinib for previously untreated ALK + advanced NCSLC in HK.

Background: The prognostic impact of comorbidities in patients with sarcomas is not well defined. The aims of this study were to examine the implications of comorbidities and abnormal peripheral blood indices in patients with sarcomas., Methods: A population-based database was assembled to extract patients with sarcoma in Hong Kong between January 2004 and March 2018. Charlson's Comorbidity Index (CCI) score and prevalence of comorbidities, neutrophil, lymphocyte and platelet counts at diagnosis were assessed. The prognostic values of CCI, neutrophil-lymphocyte (NLR) and platelet-lymphocyte ratios (PLR) were estimated using Cox proportional hazard models. Restricted cubic spline plots were used to explore the association of baseline NLR and PLR with all-cause and cancer-specific mortality., Results: Among 3358 eligible patients with sarcomas, 52.2% died after a median 26 months of follow-up. The most common comorbidities were diabetes mellitus (9.8%) and cerebrovascular disease (4.8%). Patients with higher CCI had higher mortality (CCI=3 vs CCI=2; HR 1.49; 95% CI 1.19 to 1.87; p<0.01; CCI ≥7 vs CCI =2; HR 3.20; 95% CI 2.62 to 3.92; p<0.001). Abnormal NLR and PLR levels were associated with higher all-cause mortality (NLR: HR 1.698, p<0.001, 95% CI 1.424 to 2.025; PLR: HR 1.346, p<0.001, 95% CI 1.164 to 1.555) and cancer-related mortality (NLR: HR 1.648, p<0.001, 95% CI 1.341 to 2.024; PLR: HR 1.430, p<0.001, 95% CI 1.205 to 1.697)., Conclusions: This is the largest population-based soft-tissue or bone sarcoma cohort worldwide. Comorbidities have significant negative prognostic impact on the survival of patients with sarcomas. Moreover, NLR and PLR are robust prognostic factors, and abnormal NLR and PLR have negative effects yet non-linear effects on survival., Competing Interests: Competing interests: HH-fL reports receipt of research funding of from MSD and Mundipharma for projects outside of this submitted work.

Background: Kirsten rat sarcoma vial oncogene ( KRAS ) is one of the most prevalent oncogenes in multiple cancer types, but the incidence is different between the Asian and non-Asian populations. The recent development of KRAS G12C targeting drug has shown great promise. It is thus important to understand the genomic landscape of KRAS G12C in a specific population., Methods: Sequencing data of 11,951 tumor samples collected from 11/2016 to 7/2019 from multiple centres in China were analyzed for KRAS mutation status. Concomitant genomic aberrations were further analyzed in tumors with KRAS G12C mutations, which were sequenced with comprehensive cancer panel including over 450 cancer-related genes. Smoking status and its correlation with KRAS were analyzed in 2,235 lung cancer cases within this cohort., Results: KRAS mutations were identified in 1978 (16.6%) patient samples. Specifically, KRAS G12C accounted for 14.5% (n=286) of all KRAS mutations. G12C was most commonly seen in lung cancer (4.3%), followed by colorectal cancer (2.5%) and biliary cancer (2.3%). Almost all patients (99.6%) with G12C mutations had concomitant genomic aberrations. These were most commonly associated with the RAS/RTK pathway including BRAF and PI3KCA mutations. Moreover, KRAS mutation was positively correlated with smoking status in lung adenocarcinomas., Conclusions: The overall incidence of KRAS G12C mutations remains low in the Chinese population. The most common tumor types harboring KRAS G12C mutations are in patients suffering from lung, colorectal and biliary cancers., Competing Interests: Conflicts of Interest: All authors have completed the ICMJE uniform disclosure form (available at http://dx.doi.org/10.21037/tlcr-20-455).

Introduction: Lorlatinib, a next-generation central nervous system-penetrant ALK/ROS1 tyrosine kinase inhibitor (TKI), is approved to treat TKI-refractory ALK-positive (ALK+) NSCLC based on results from a phase 2 study., Methods: A real-world analysis was performed on ALK+ or ROS1-positive (ROS1+) patients with NSCLC enrolled in lorlatinib early or expanded access programs in Hong Kong, Singapore, South Korea, Taiwan, Thailand, and the United States., Results: A total of 95 patients with NSCLC (76 ALK+ and 19 ROS1+) were analyzed. Among ALK+ patients treated with less than two previous TKIs, two or more previous TKIs, and three or more previous TKIs, the objective response rates (ORR) and median progression-free survival (mPFS) were 42% (95% confidence interval [CI]: 26-59; n = 38) and not reached (NR) (95% CI: 4.5-NR; n = 45), 35% (95% CI: 22-49; n = 55) and 11.2 months (95% CI: 4.5-NR; n = 66), and 18% (95% CI: 4-43; n = 17) and 6.5 months (95% CI: 3.5-11.6; n = 21), respectively. The ORRs and mPFSs were 13% (95% CI: 0-53; n = 8) and 9.2 months (95% CI: 3.3-NR; n = 9) for patients treated with one second-generation ALK TKI as the only ALK TKI received. For ROS1+ patients, ORRs and mPFSs were 41% (95% CI: 18-67; n = 17) and 11.9 months (95% CI: 6.4-NR; n = 19). The intracranial ORRs were 35% (95% CI: 22-49) and 55% (95% CI: 23-83) for 52 ALK+ and 11 ROS1+ patients. mPFS was 9.3 months (95% CI: 1.0-NR; n = 13) for patients with leptomeningeal carcinomatosis. No new safety signals were noted., Conclusion: Lorlatinib exhibited meaningful activity in TKI-refractory ALK+ or ROS1+ patients with NSCLC enrolled in early or expanded access programs., (Copyright © 2020 International Association for the Study of Lung Cancer.

Despite significant medical advances, glioblastoma multiforme (GBM) remains a formidable therapeutic challenge. Advent of targeted capture sequencing and patients-derived organoid cultures may hold the key to scientifically sound individualized treatment approaches. We report on our initial experience of using the combination of these two technologies to create a tailored approach of systemic therapies for a patient with GBM, which challenges the conventional treatment paradigm, as well as specifically highlighting the complexities of such an approach and the potential for a more favorable treatment outcome., (Copyright © 2020.

Purpose of Review: Genetic aberrations resulting in tropomyosin receptor kinase (TRK) fusion proteins can drive oncogenesis and are postulated to occur in up to 1% of solid tumours. However, TRK fusions in adult sarcomas are rare and there is a significant challenge in identifying patients with sarcomas harbouring TRK fusions in the clinical setting. Despite a recent European Society of Medical Oncology consensus article regarding screening of tumours for TRK fusions, economical and practical limitations present a barrier to widespread screening of sarcomas., Recent Findings: Larotrectinib and entrectinib are pan-TRK inhibitors which have both received FDA approval for the management of solid tumours harbouring NTRK fusions. Initial results of a number of clinical trials have demonstrated promising efficacy and safety data, including dramatic and durable responses in patients with sarcomas. As such, TRK inhibitors represent a promising treatment option in a small cohort of adult sarcoma patients, where currently treatment options are limited. The emergence of acquired resistance is a concern associated with TRK inhibitor therapy and a number of second-generation agents targeting TRK kinase mutations driving acquired resistance have entered early-phase clinical trials., Summary: With the growing appreciation of the implications of TRK fusions, this review will summarize the emerging clinical trial data of TRK inhibitors in sarcomas. Although in their infancy, clinical trial results are encouraging, and as further results and analyses are released, we will have a greater understanding of their impact on clinical practice and the management of patients with sarcomas.
