Unresectable pleural mesothelioma is a poor prognosis disease. Improvement in overall survival (OS) has been shown with PEMETREXED combined with CISPLATIN. BEVACIZUMAB combined with chemotherapy is associated with an improvement in OS, compared to chemotherapy alone, but is not supported by health insurance everywhere.Immune Checkpoint Inhibition (ICI) monotherapy seemed to be promising but is controversial. ICI combination showed significant results. NIVOLUMAB, an anti-Programmed-Death-receptor 1, associated with IPILIMUMAB, an anti-Cytotoxic-T-Lymphocyte-Associated-protein 4, was evaluated in two phase II trials and a phase III trial, recently published. This combination led to a significant benefit in survival in first line compared to chemotherapy (OS 18.1 months (95%CI (16.8-21.4)) vs 14.1 (95%CI (12.4-16.2) HR 0.74 (95%CI 0.6-0.91) p = 0.002).These results represent a big step in unresectable pleural mesothelioma. The benefit in non-epithelioid subtype is impressive (OS 18.1 months (95%CI 12.2-22.8) vs 8.8 months 95%CI (7.4-10.2) HR 0.46 (95%CI (0.31-0.68))). Benefit in epithelioid subtype (OS 18.7 months 95%CI (16.9-22) vs 16.5 95%CI (14.9-20.5) HR 0.86 95%CI (0.69-1.08)) is similar to the benefit of the combination of BEVACIZUMAB and chemotherapy. Identification of predictive biomarkers is needed to identify patients who are most likely to benefit from each therapeutic strategy.

Purpose: Targeted therapies (TT) and immune checkpoint blockers (ICB) have revolutionized the approach to non–small cell lung cancer (NSCLC) treatment in the era of precision medicine. Their impact as switch maintenance therapy based on molecular characterization is unknown. Patients and Methods: SAFIR02-Lung/IFCT 1301 was an open-label, randomized, phase II trial, involving 33 centers in France. We investigated eight TT (substudy-1) and one ICB (substudy-2), compared with standard-of-care as a maintenance strategy in patients with advanced EGFR, ALK wild-type (wt) NSCLC without progression after first-line chemotherapy, based on high-throughput genome analysis. The primary outcome was progression-free survival (PFS). Results: Among the 175 patients randomized in substudy-1, 116 received TT (selumetinib, vistusertib, capivasertib, AZD4547, AZD8931, vandetanib, olaparib, savolitinib) and 59 standard-of-care. Median PFS was 2.7 months [95% confidence interval (CI), 1.6–2.9] with TT versus 2.7 months (1.6–4.1) with standard-of-care (HR, 0.97; 95% CI, 0.7–1.36; P = 0.87). There were no significant differences in PFS within any molecular subgroup. In substudy-2, 183 patients were randomized, 121 received durvalumab and 62 standard-of-care. Median PFS was 3.0 months (2.3–4.4) with durvalumab versus 3.0 months (2.0–5.1) with standard-of-care (HR, 0.86; 95% CI, 0.62–1.20; P = 0.38). Preplanned subgroup analysis showed an enhanced benefit with durvalumab in patients with PD-L1 tumor proportion score (TPS) ≥1%, (n = 29; HR, 0.29; 95% CI, 0.11–0.75) as compared with PD-L1 Conclusions: Molecular profiling can feasibly be implemented to guide treatment choice for the maintenance strategy in EGFR/ALK wt NSCLC; in this study it did not lead to substantial treatment benefits beyond durvalumab for PD-L1 ≥ 1 patients.

Lung cancer remains the most frequent cause of brain metastases (BMs) and is responsible for high morbidity and mortality. Intracranial response to systemic treatments is inconsistent due to several mechanisms: genomic heterogeneity, blood-tumor barrier, and the brain-specific microenvironment. We conducted a study using data from the SAFIR02-LUNG trial. The primary objective was to compare the molecular profiles of non-small-cell lung cancer (NSCLC) with or without BMs. The secondary objective was to explore central nervous system (CNS) outcomes with various maintenance treatment regimens.In total, 365 patients harboring interpretable molecular data were included in this analysis. Clinical and biological data were collected. Genomic analyses were based on array-comparative genomic hybridization and next-generation sequencing (NGS) following the trial recommendations.Baseline genomic analyses of copy number variations identified a 24-gene signature specific to lung cancer BM occurrence, all previously known to take part in oncogenesis. NGS analysis identified a higher proportion of KRAS mutations in the BM-positive group (44.3% versus 32.3%), especially G12C mutations (63% versus 47%). Protein interaction analyses highlighted several functional interactions centered on EGFR. Furthermore, the risk of CNS progression was decreased with standard pemetrexed maintenance therapy. The highest rate of CNS progression was observed with durvalumab, probably because of the specific intracranial immune microenvironment.This work identified a 24-gene signature specific to lung cancer with BM. Further studies are needed to precisely determine the functional implications of these genes to identify new therapeutic targets for the treatment of lung cancer with BM.

Clinical trials frequently include multiple end points that mature at different times. The initial report, typically based on the primary end point, may be published when key planned co-primary or secondary analyses are not yet available. Clinical Trial Updates provide an opportunity to disseminate additional results from studies, published in JCO or elsewhere, for which the primary end point has already been reported.In the longest follow-up, to our knowledge, for a KRASG12C inhibitor, we assessed the long-term efficacy, safety, and biomarkers of sotorasib in patients with KRAS G12C-mutated advanced non-small-cell lung cancer (NSCLC) from the CodeBreaK 100 clinical trial (ClinicalTrials.gov identifier: NCT03600883). This multicenter, single-group, open-label phase I/phase II trial enrolled 174 patients with KRAS G12C-mutated, locally advanced or metastatic NSCLC after progression on prior therapies. Patients (N = 174) received sotorasib 960 mg once daily with the primary end points for phase I of safety and tolerability and for phase II of objective response rate (ORR). Sotorasib produced an ORR of 41%, median duration of response of 12.3 months, progression-free survival (PFS) of 6.3 months, overall survival (OS) of 12.5 months, and 2-year OS rate of 33%. Long-term clinical benefit (PFS ≥ 12 months) was observed in 40 (23%) patients across PD-L1 expression levels, in a proportion of patients with somatic STK11 and/or KEAP1 alterations, and was associated with lower baseline circulating tumor DNA levels. Sotorasib was well tolerated, with few late-onset treatment-related toxicities, none of which led to treatment discontinuation. These results demonstrate the long-term benefit of sotorasib, including in subgroups with poor prognosis. ispartof: J Clin Oncol vol:41 issue:18 pages:3311-3317 ispartof: location:United States status: published

Study protocol

International audience; Background: Previous reports showed limited efficacy of immune checkpoint inhibitors as single-agent treatment for non-small cell lung cancer (NSCLC) with epidermal growth factor receptor (EGFR) mutation or ALK/ROS1 fusion. We aimed at evaluating the efficacy and safety of immune checkpoint inhibitor combined with chemotherapy and bevacizumab (when eligible) in this patient subgroup.Methods: We conducted a French national open-label multicentre non-randomised non-comparative phase II study in patients with stage IIIB/IV NSCLC, oncogenic addiction (EGFR mutation or ALK/ROS1 fusion), with disease progression after tyrosine kinase inhibitor and no prior chemotherapy. Patients received platinum, pemetrexed, atezolizumab, bevacizumab (PPAB cohort) or, if not eligible to bevacizumab, platinum-pemetrexed-atezolizumab (PPA cohort). The primary end-point was the objective response rate (RECIST v1.1) after 12 weeks, evaluated by blind independent central review.Results: 71 patients were included in PPAB cohort and 78 in PPA cohort (mean age, 60.4/66.1 years; women 69.0%/51.3%; EGFR mutation, 87.3%/89.7%; ALK rearrangement, 12.7%/5.1%; ROS1 fusion, 0%/6.4%, respectively). After 12 weeks, objective response rate was 58.2% (90% confidence interval [CI], 47.4-68.4) in PPAB cohort and 46.5% (90% CI, 36.3-56.9) in PPA cohort. Median progression-free survival and overall survival were 7.3 (95% CI 6.9-9.0) months and 17.2 (95% CI 13.7-NA) months in PPAB cohort and 7.2 (95% CI 5.7-9.2) months and 16.8 (95% CI 13.5-NA) months in PPA cohort, respectively. Grade 3-4 adverse events occurred in 69.1% of patients in PPAB cohort and 51.4% in PPA cohort; Grade 3-4 atezolizumab-related adverse events occurred in 27.9% and 15.3%, respectively.Conclusion: Combination approach with atezolizumab with or without bevacizumab and platinum-pemetrexed achieved promising activity in metastatic EGFR-mutated or ALK/ROS1-rearranged NSCLC after tyrosine kinase inhibitor failure, with acceptable safety profile.

BackgroundIntracranial progression after curative treatment of early-stage non-small cell lung cancer (NSCLC) occurs from 10 to 50% and is difficult to manage, given the heterogeneity of clinical presentations and the variability of treatments available.The objective of this study was to develop a mechanistic model of intracranial progression to predict survival following a first brain metastasis (BM) event.MethodsData included early-stage NSCLC patients treated with a curative intent who had a BM as the first and single relapse site (N=31).We propose a mechanistic mathematical model to estimate the amount and sizes of (visible and invisible) BMs. The two key parameters of the model areα, the proliferation rate of a single tumor cell; andμ, the per day, per cell, probability to metastasize. The predictive value of these individual computational biomarkers was evaluated.FindingsThe model was able to correctly describe the number and size of metastases at the time of first BM relapse for 20 patients. Parametersαandμwere significantly associated with overall survival (OS) (HR 1.65 (1.07-2.53) p=0.0029 and HR 1.95 (1.31-2.91) p=0.0109, respectively). Adding the computational markers to the clinical ones significantly improved the predictive value of OS (c-index increased from 0.585 (95% CI 0.569-0.602) to 0.713 (95% CI 0.700-0.726), pInterpretationWe demonstrated that our model was applicable to brain oligoprogressive patients in NSCLC and that the resulting computational markers had predictive potential. This may help lung cancer physicians to guide and personalize the management of NSCLC patients with intracranial oligoprogression.SIGNIFICANCE STATEMENTNon-small cell lung cancer is difficult to manage when brain metastases are present. This study presents a mathematical model that can be calibrated on individual patients’ data early in the treatment course to explain the growth dynamics of brain metastases and demonstrates that the mathematically derived parameters can serve as predictive tool in clinical routine care.Highlights-Mechanistic mathematical modeling allows individualized prognosis for lung cancer patients at first brain metastatic relapse-Individual model-derived computational parameters identifies high-risk patients in terms of brain metastasis progression and survival-Prognostic features include quantification of the number and sizes of both clinically visible and invisible brain metastases

Selpercatinib; Lung cancer; Safety Selpercatinib; Cáncer de pulmón; Seguridad Selpercatinib; Càncer de pulmó; Seguretat PURPOSE Selpercatinib, a first-in-class, highly selective, and potent CNS-active RET kinase inhibitor, is currently approved for the treatment of patients with RET fusion–positive non–small-cell lung cancer (NSCLC). We provide a registrational data set update in more than double (n = 316) of the original reported population (n = 144) and better characterization of long-term efficacy and safety. METHODS Patients were enrolled to LIBRETTO-001, a phase I/II, single-arm, open-label study of selpercatinib in patients with RET-altered cancers. An analysis of patients with RET fusion–positive NSCLC, including 69 treatment-naive and 247 with prior platinum-based chemotherapy, was performed. The primary end point was objective response rate (ORR; RECIST v1.1, independent review committee). Secondary end points included duration of response (DoR), progression-free survival (PFS), overall survival, and safety. RESULTS In treatment-naive patients, the ORR was 84% (95% CI, 73 to 92); 6% achieved complete responses (CRs). The median DoR was 20.2 months (95% CI, 13.0 to could not be evaluated); 40% of responses were ongoing at the data cutoff (median follow-up of 20.3 months). The median PFS was 22.0 months; 35% of patients were alive and progression-free at the data cutoff (median follow-up of 21.9 months). In platinum-based chemotherapy pretreated patients, the ORR was 61% (95% CI, 55 to 67); 7% achieved CRs. The median DoR was 28.6 months (95% CI, 20.4 to could not be evaluated); 49% of responses were ongoing (median follow-up of 21.2 months). The median PFS was 24.9 months; 38% of patients were alive and progression-free (median follow-up of 24.7 months). Of 26 patients with measurable baseline CNS metastasis by the independent review committee, the intracranial ORR was 85% (95% CI, 65 to 96); 27% were CRs. In the full safety population (n = 796), the median treatment duration was 36.1 months. The safety profile of selpercatinib was consistent with previous reports. CONCLUSION In a large cohort with extended follow-up, selpercatinib continued to demonstrate durable and robust responses, including intracranial activity, in previously treated and treatment-naive patients with RET fusion–positive NSCLC.

A phase Ia/Ib trial of metronomic oral vinorelbine (MOV) driven by a mathematical model was performed in heavily pretreated metastatic Non-Small Cell Lung Cancer or Pleural Mesothelioma patients. Disease Control Rate, progression free survival, toxicity and PK/PD were the main endpoints.Best MOV scheduling was selected using a simplified phenomenological, semi-mechanistic model with a total weekly dose of 150-mg vinorelbine. Computation of individual PK parameters was performed using population approach.The mathematical model proposed the following metronomic schedule for a 150-mg weekly dose of vinorelbine: 60 mg D1, 30 mg D2, 60 mg D4. A total of 37 heavily pre-treated patients (30 evaluable) were enrolled. Grade III/IV neutropenia was observed in 30% patients. Median PFS was 11 weeks. Disease Control Rate was 73% (i.e.; 13% partial response and 60% stable disease). A large variability in drug exposure (AUCMOV was characterized by important variability in drug exposure among patients. However, and despite being all heavily pre-treated, 73% of disease control rate and 11 weeks PFS were achieved with manageable toxicities. PK/PD relationships yielded conflicting results depending on the initial tumor burden and BSA, suggesting that patients should be carefully selected prior to be scheduled for metronomic regimen. Possible role NLR could play as a predictive marker suggests immunomodulating features with MOV.

The COVID-19 vaccination campaign began in December 2020, in France, and primarily targeted the oldest people. Our study aimed to determine the level of acceptance of vaccination in a population of older patients with cancer.From January 2021, we offered vaccination with the BNT162b2 COVID-19 vaccine to all patients 70 years and older referred to our geriatric oncology center in Marseille University Hospital (AP-HM) for geriatric assessment before initiation of an oncological treatment. Objectives were to evaluate acceptance rate of COVID-19 vaccination and to assess vaccine safety, reactogenicity, and efficacy two months after the first dose.Between January 18, 2021 and May 7, 2021, 150 older patients with cancer were offered vaccination after a geriatric assessment. The majority were men (61.3%), with a mean age of 81 years. The two most frequent primary tumors were digestive (29.4%) and thoracic (18%). The vaccine acceptance rate was 82.6% and the complete vaccination rate (2 doses) reached 75.3%. Among the vaccinated patients, 15.9% reported mild side effects after the first dose and 23.4% after the second dose, mostly arm pain and fatigue. COVID-19 cases were observed in 5.1% of vaccinated patients compared with 16.7% in unvaccinated patients. Of the 22 vaccinated patients who agreed to have their serum tested, 15 had antibodies against the spike protein at day 21 after the first dose.Our study showed a high acceptance rate of COVID-19 vaccination, with good tolerance in this frail population. These results highlight the benefits of organizing vaccination campaigns at the very beginning of oncological management in older patients.This study was registered May 23, 2019 in ClinicalTrials.gov (NCT03960593).

Objectives Quantify the burden of central nervous system (CNS) metastases on health-related quality of life (HRQoL) and healthcare resource use (HRU) in patients with advanced non-small-cell lung cancer (NSCLC) from a prospective European study in clinical practice, utilising clinical trial inclusion criteria. Materials and Methods Patients ≥18 years, with metastatic NSCLC, Eastern Oncology C0operative Group (ECOG) performance status 0–2 and life expectancy ≥12 weeks were enrolled in two cohorts by baseline CNS metastases status. Demographics, clinical characteristics, NSCLC management data, HRQoL and HRU were collected at baseline and two follow-up visits (Visits 2 and 3, 6 weeks apart). HRQoL was assessed using validated questionnaires. Results 162 patients were enrolled (n = 80 CNS cohort, n = 82 non-CNS cohort). Baseline characteristics were balanced, but CNS patients were younger (mean ± standard deviation age: 62.1 ± 9.6 vs 65.6 ± 9.7 years, p = 0.021) with a lower body mass index (13.8 % underweight [ Conclusion These data from clinical practice show minor differences in HRQoL/HRU between patients with advanced NSCLC with/without CNS metastases when applying selected clinical trial criteria. Although follow-up was short, HRQoL scores were similar between cohorts at all visits, supporting the wider inclusion of selected patients with CNS disease into clinical trials.

Resume L’immunotherapie par inhibiteurs de points de controle immunitaires (ICI) a recemment revolutionne la prise en charge de nombreux cancers solides. Les ICI ont pour but de restaurer l’action du lymphocyte T sur la cellule tumorale en inhibant des signaux de regulation negative impliques dans la cancerogenese. L’utilisation en routine des ICI depuis quelques annees a permis d’en identifier le profil de tolerance. Les effets secondaires sont immuno-medies, secondaires a la stimulation du systeme immunitaire induite par le traitement. Ces effets secondaires restent rares en comparaison avec ceux observes avec les chimiotherapies standards mais sont potentiellement graves, et peuvent remettre en cause la poursuite d’un traitement efficace. De nombreuses nouvelles immunotherapies sont en cours de developpement, dont les mecanismes d’action sont varies, mais toujours dans le but de restaurer la reponse immunitaire anti-tumorale. De nouvelles molecules impliquent de nouveaux profils de tolerance, d’autant plus qu’un grand nombre d’essais cliniques evaluent des associations d’immunotherapies. Etant donne la multitude de traitements a l’etude, la connaissance et la prise en charge de ces toxicites sera un enjeu majeur dans le choix des nouvelles sequences therapeutiques de nombreuses pathologies tumorales. En effet, malgre le pronostic sombre des types tumoraux concernes par ces innovations, l’amelioration progressive des donnees de survie dans ces pathologies entraine une exposition au traitement de plus en plus longue. La tolerance et la qualite de vie pendant le traitement deviennent donc des arguments majeurs de la decision therapeutique.

Molecular testing for genomic variants is recommended in advanced non-small cell lung cancer (NSCLC). Standard tissue biopsy is sometimes infeasible, procedurally risky, or insufficient in tumor tissue quantity. We present the analytical validation and concordance study of EGFR variants using a new 17-gene liquid biopsy assay (NCT02762877). Of 144 patients enrolled with newly diagnosed or progressive stage IV nonsquamous NSCLC, 140 (97%) had liquid assay results, and 117 (81%) had both EGFR blood and tissue results. Alterations were detected in 58% of liquid samples. Overall tissue-liquid concordance for EGFR alterations was 94.0% (95% CI 88.1%, 97.6%) with positive percent agreement of 76.7% (57.7%, 90.1%) and negative percent agreement of 100% (95.8%, 100%). Concordance for ALK structural variants was 95.7% (90.1%, 98.6%). This assay detected alterations in other therapeutically relevant genes at a rate similar to tissue analysis. These results demonstrate the analytical and clinical validity of this 17-gene assay.

BackgroundImmune checkpoint inhibitors (ICIs) are now a therapeutic standard in advanced non-small cell lung cancer (NSCLC), but strong predictive markers for ICIs efficacy are still lacking. We evaluated machine learning models built on simple clinical and biological data to individually predict response to ICIs.MethodsPatients with metastatic NSCLC who received ICI in second line or later were included. We collected clinical and hematological data and studied the association of this data with disease control rate (DCR), progression free survival (PFS) and overall survival (OS). Multiple machine learning (ML) algorithms were assessed for their ability to predict response.ResultsOverall, 298 patients were enrolled. The overall response rate and DCR were 15.3 % and 53%, respectively. Median PFS and OS were 3.3 and 11.4 months, respectively. In multivariable analysis, DCR was significantly associated with performance status (PS) and hemoglobin level (OR 0.58, pConclusionCombination of simple clinical and biological data could accurately predict disease control rate at the individual level.Highlights-Machine learning applied to a large set of NSCLC patients could predict efficacy of immunotherapy with a 69% accuracy using simple routine data-Hemoglobin levels and performance status were the strongest predictors and significantly associated with DCR, PFS and OS-Neutrophils-to-lymphocyte ratio was also associated with outcome-Benchmark of 8 machine learning models

Introduction La première vague de COVID-19 a nécessité des modifications des pratiques médicales selon les recommandations des sociétés savantes. En oncologie thoracique, le pembrolizumab a été doublé à 400 mg toutes les 6 semaines, le nivolumab à 480 mg toutes les 4 semaines. L’objectif de notre étude était d’évaluer l’impact sur la qualité de vie, l’état psychologique et la tolérance de ce nouveau schéma d’administration. Méthodes Durant la première vague, nous avons inclus des patients suivis en oncologie thoracique chez qui le schéma d’administration de l’immunothérapie avait été modifié et utilisé le Quality of Life Questionnaire-30 pour mesurer leur qualité de vie et l’échelle Hospital Anxiety Depression (HAD) pour évaluer l’état psychologique. Nous avons également précisé les préférences des patients concernant le schéma d’administration et les effets indésirables présentés.

The combination of increased fundamental knowledge and the pharmaceutical pipeline has allowed the development of various tyrosine kinase inhibitors, targeting numerous molecular alterations. These drugs are now available in daily practice and have transformed survival outcomes for patients harboring EGFR, ALK or ROS1 alterations. Multiple clinical trials are now ongoing in order to increase the number of approved drugs, thus overcoming the issues of rare mutations and tyrosine kinase inhibitors resistance. Immune checkpoint inhibitors development has also changed lung cancer outcomes, but underwhelming response rates highlight the need for immune biomarkers. While PD-L1 expression was the first approved immune biomarker, it has shown several limitations and new biomarkers have to be identified to predict response or resistance to immune checkpoint inhibitors. Testing methods, molecular results and targeted therapeutic schedules will be harmonized in the coming years, with the help of dedicated molecular multidisciplinary boards.Keywords: molecular biology, targeted therapy, lung cancer, immunotherapy, biomarkers

El cancer de pulmon es el cancer que mas muertes provoca en el mundo. Tiene relacion principalmente con el tabaco, pero tambien puede presentarse en contextos de intoxicacion profesional (por ejemplo, por amianto) o bien, mas raramente, en ausencia de causa evidente. Este articulo tiene por objetivo exponer la epidemiologia y las causas mas frecuentes, las presentaciones clinicas, histologicas y biologicas, la clasificacion y el tratamiento, incluidos los principales tratamientos de los canceres de pulmon llamados de celulas pequenas y no pequenas.

Background: Immune checkpoint inhibitors (ICI)s were recently approved for the treatment of advanced non-small cell lung cancer (NSCLC). Whereas brain metastases (BM) are frequent in NSCLC patients, data are missing regarding ICIs intracranial efficacy and tolerance in patients with BM from NSCLC. Methods: This retrospective study was performed in the Multidisciplinary Oncology and Therapeutic Innovation department, Marseille, France between April 2013 and February 2016. Data from patients with NSCLC with at least one BM, and treated with ICIs (anti-PD1, anti-PDL1 or anti-CTL4) were analyzed. Clinical, biological data and outcomes were retrieved from electronic patients’ records. We assessed ICIs intracranial efficacy and tolerance. Results: Data from 55 patients were analyzed. Objective Response Rate (ORR) and Disease Control Rate (DCR) were respectively of 1.8 and 36.4%. Median overall survival was 17.2 months and median progression free survival was 2.9 months. Intracranial ORR (icORR) and intracranial DCR (icDCR) were respectively 16.4% and 45.5%. Both were independent of smoking status, intracranial treatment, performance status, pathology, molecular profile and the presence or number of BM at diagnosis. However, there was a trend towards an association between icORR and ECOG PS (p = 0.05), tobacco status (p = 0.057) and intracranial treatment. Adverse events were seen in 38.2% patients without identified predictive factor. Neurological symptoms appeared in 5.5% patients during immunotherapy and improved in 3.63% patients. Conclusions: ICIs can be used safely on patients with BM from NSCLC. However, intracranial response is heterogeneous in such patients and we showed ECOG PS, tobacco smoking and intracranial treatment to be associated with an improved icORR. This is the first study looking for predictive factors of intracranial response of ICIs in patients with BM from NSCLC.

International audience; Purpose: An assessment of the impact of functional status (FS) evaluated using a combination of Activities of Daily Living (ADL) and the short version of the Instrumental Activities of Daily Living (IADL), on 3- and 6- month mortality and on 3-month unplanned hospitalizations in older patients treated for lung cancers.Method and objectives: This observational retrospective study was conducted between September 2015 and January 2019 at Marseille University Hospital (AP-HM). During this period, all consecutive outpatients aged 70 years or older referred for a comprehensive geriatric assessment (CGA) before the initiation of lung cancer treatment were enrolled.Results: Two hundred twenty-seven patients were analyzed: the median age was 78.7 years and 74.0% were male. Almost half of the patients were metastatic (45.4%). Concerning FS, 41.9% of patients had no ADL-IADL impairment, 30.0% had either IADL or ADL impairment, and both ADL-IADL were impaired for 28.1%. Impaired ADL-IADL was associated with poor nutritional status, depression, mobility, and cognitive disorders. In a logistic regression model, ADL or IADL impairment (aOR = 2.1; 95% CI [1.0-4.2]; p = 0.037) and impaired ADL-IADL (aOR = 2.6; 95% CI [1.2-5.3]; p = 0.012) were independently associated with a higher risk of unplanned hospitalizations within 3 months. In the multivariate Cox model, 6-month mortality risk was independently associated with impaired ADL-IADL (aHR = 2.3; 95% CI [1.3-4.4]; p = 0.008).Conclusion: The combination of ADL and IADL scales to assess FS is a prognostic marker of the mortality risk at 6 months in older patients with lung cancer and should be more largely used by oncologists in treatment decision making.

International audience; Background: Lung cancer affects older adults and is the leading solid tumor in terms of death. A Comprehensive Geriatric Assessment (CGA) is recommended before cancer treatment to guide therapy management.Patients and methods: This study was conducted between September 2015 and January 2019. During this period of time, all consecutive older outpatients referred for a CGA before initiation of lung or thoracic tumor treatment were included. The objectives were to describe the impact of geriatric factors on unplanned hospitalizations and overall survival (OS). The study was approved by a local ethics committee.Results: Overall, 228 patients were recruited. The median age was 78.7 ± 5 years. The majority (82%) of patients were diagnosed with non-small-cell lung cancer, and the most common (40.4%) treatment was systemic therapy. In multivariate analysis, factors associated with unplanned hospitalizations within the first 3 months were male gender (adjusted odds ratio [aOR], 3.3; 95% confidence interval [CI], 1.5-7.2), systemic therapy (aOR, 2.6; 95% CI, 1.1-6.2), and fall history (aOR, 3.6; 95% CI, 1.6-8.2). Factors associated with a decrease in OS in the multivariate Cox model analysis were male gender (hazard ratio [HR], 3.9; 95% CI, 2.1-7.3), stage IV (HR, 1.6; 95% CI, 1.0-2.6), G8 ≤ 14 (HR, 3.5; 95% CI, 1.1-11.4), systemic therapy (HR, 2.6; 95% CI, 1.2-5.5), Eastern Cooperative Oncology Group performance status ≥ 2 (HR, 2.0; 95% CI, 1.2-3.4), and impaired handgrip strength (HR, 1.6; 95% CI, 1.0-2.5).Conclusion: G8 score and handgrip strength are important to predict OS in older adults treated for thoracic tumors. In the CGA, fall history was associated with unplanned hospitalization.

Introduction Recurrent venous thromboembolism (VTE) despite curative anticoagulation is frequent in patients with cancer. Identifying patients with a high risk of recurrence could have therapeutic implications. A prospective study was designed to validate the Ottawa risk score of recurrent VTE in cancer patients. Methods In a prospective multicenter observational cohort, adult cancer patients with a recent diagnosis of symptomatic or incidental lower limb deep vein thrombosis or pulmonary embolism (PE) were treated with tinzaparin for 6 months. The primary endpoint was the recurrence of symptomatic or asymptomatic VTE within the first 6 months of treatment. All clinical events were centrally reviewed and adjudicated. Time-to-event outcomes were estimated by the Kalbfleisch and Prentice method to take into account the competing risk of death. A C-statistic value of > 0.70 was needed to validate the Ottawa score. Results A total of 409 patients were included and analyzed on an intention-to-treat basis. Median age was 68 years, 60.4% of patients had PE, and VTE was symptomatic in 271 patients (66.3%). The main primary sites were lung (31.3%), lower digestive tract (14.4%), and breast (13.9%) cancers. The Ottawa score was high (≥ 1) in 58% of patients. The 6-month cumulative incidence of recurrent VTE was 7.3% (95% confidence interval [CI]: 4.9–11.1) overall, and 5.0% (95% CI: 2.3–10.8) versus 9.1% (95%CI: 6.1–13.6) in the Ottawa low versus high risk groups, respectively. The C-statistic value was 0.60 (95% CI: 0.55–0.65). Conclusion In this prospective cohort of patients with cancer receiving tinzaparin for VTE, the Ottawa score failed to accurately predict recurrent VTE.

Lung cancer affects older and older old adults and is the leading cause of death by cancer. Comprehensive Geriatric Assessment (CGA) is recommended before and during cancer treatment to guide therapy management in this population.This study was conducted between September 2015 and January 2019 at Marseille University Hospital (AP-HM). During this period, all consecutive outpatients 70 years or older referred for a CGA before initiation of lung cancer treatment were enrolled. The objective of this study was to compare lung and thoracic cancer management of octogenarians (≥80 years) and their geriatric profile versus patients aged 70 to 79 years (80 years).In our study, 228 patients were recruited. The median age was 78.7 ± 5 years. There were 94 octogenarians (41.2%), 36.2% of them were diagnosed with stage IV neoplasm and the most common treatment was chemotherapy (43.6%). The logistic regression analysis highlights that handgrip strength was the most commonly impaired domain (OR 2.3; 95% CI [1.3-4.3]) in octogenarians and that they are more likely than their younger counterparts to be treated by targeted therapy (OR 9.8; 95% CI [1.0-92.9]). Overall survival (OS) was similar in both age groups (log rank = 0,95).In our study, octogenarians and patients80 years had equivalent survival, across the different thoracic cancer treatments and tumor stages. Measure of muscle strength in CGA could be very useful in a clinical setting to help improve the management of older old patients treated for lung or thoracic cancer.

Introduction: Sotorasib, a first-in-class KRASG12C inhibitor, has been FDA-approved for adults with KRAS p.G12C-mutated locally advanced or metastatic NSCLC who received prior systemic therapies based on the Phase 1/2 global, single-arm CodeBreaK100 trial. We will report the longest follow-up for a KRASG12C inhibitor, including 2-year survival, safety, and genomic profiles associated with durable clinical benefit. Methods: Sotorasib was administered orally at 960 mg once daily to patients who progressed on prior therapies and had KRAS p.G12C-mutated locally advanced, metastatic NSCLC. Primary endpoint was objective response rate (ORR) assessed by central review. Key secondary endpoints included duration of response (DOR), progression-free survival (PFS), overall survival (OS), and safety. In an exploratory analysis, baseline tumor tissue and/or plasma samples were collected and analyzed for genomic alterations. Tumor samples were analyzed for PD-L1 levels to evaluate correlates with prolonged tumor response, defined as patients with PFS ≥ 12 months, in comparison with those with PFS ≤ 3 months. Results: In the first analysis of the combined Phase 1 and Phase 2 study (N=174), the median number of prior lines of therapy was 2.0 (range 1-4+). 90.2% received prior anti-PD1 or anti PD-L1 treatment; 82.8% received both prior platinum-based chemotherapy and anti-PD1/PD-L1. Updated ORR by central review was 40.7% (95% CI: 33.2, 48.4) and median DOR was 12.3 months (7.1, 14.6). Median PFS and OS was 6.3 months (95% CI: 5.3, 8.2) and 12.5 months (10.0, 17.8). One and two-year OS was 50.8% and 30.3%. Sotorasib was well-tolerated in the long-term with mild and manageable toxicities, and no new safety signals emerged. Prolonged tumor response was observed across PD-L1 expression, including in tumors with low PDL-1 expression and STK11 co-mutation that may derive less benefit from immunotherapy. Conclusions: In the longest follow-up of any KRASG12C inhibitor, sotorasib continued to demonstrate a favorable safety profile and durable efficacy, including a 2-year OS observed in 30% of patients. Current analyses continue to support long-term clinical benefit across subgroups in patients with KRAS p.G12C-mutated NSCLC, and additional biomarker data will be presented. Citation Format: Grace K.
