RESUMO
Over the past 20 years, several innovative therapies have been implemented in the treatment of lung cancer that have had reported survival benefits in clinical trials. Whether these improvements translate into the clinic setting has not been studied yet. We retrospectively analyzed all patients consecutively treated at Institute Curie for metastatic lung cancer. Diagnosis date was used to define three periods, based on the approvals of novel treatment strategies in the first-line setting, including targeted therapies in 2010 and immunotherapy in 2018. Endpoints included Overall survival (OS), survival rate of 2 years and 5 years, and a conditional survival rate of 2 years (if still alive at 6 months from treatment initiation). A total of 673 patients were identified for Period 1-2000 to 2009, 752 for Period 2-2010 to 2017, and 768 for Period 3-2018 to 2020. Median OS in the whole cohort was 11.1, 15.5, and 16.2 months, respectively. Median OS for patients with NSCLC or SCLC was 11.2, 17.2, and 18.2 months, or 10.9, 11.7, and 11.2 months, respectively. The two-year conditional survival was more favorable for NSCLC than SCLC patients. Outcomes were statistically higher for women as compared to men in all periods and all subgroups. Survival of patients with metastatic lung cancer has improved over the past 20 years, mostly in NSCLC, along with the implementation of novel treatment strategies.
RESUMO
BACKGROUND: First-line standard-of-care for unresectable, pleural mesothelioma (PM) changed with the phase 3 CheckMate 743 study results, showing that nivolumab plus ipilimumab (Nivo + Ipi) significantly extended overall survival (OS) versus platinum + pemetrexed chemotherapy for PM (median OS 18.1 versus 14.1 months; hazard ratio: 0.74; p = 0.002). Efficacy and safety data in real-world (rw) settings are needed to confirm these results. METHODS: This French multicenter, retrospective cohort study was undertaken to assess the outcomes of treatment-naïve PM patients given Nivo + Ipi via an early-access program (EAP). The primary objective was investigator-assessed real world -progression-free survival (PFS). The secondary objectives were the combination's -overall survival (OS) and safety. RESULTS: From 1 April 2021 to 15 Feb 2022, the analysis included 201 of the 305 EAP-enrolled patients treated in 63 centers (79.6 % men; median age: 75 years; 91.8 % Eastern Cooperative Oncology Group performance status (ECOG-PS) 0/1; 74.5 % epithelioid histology). With median (95 % CI) follow-up for all patients of 18.4 (17.7-19.2) months, -PFS and OS were 6.3 (5.3-7.5) and 18.9 (17.6-not reached (NR)) months, with 1-year OS at 66.4 % (60.1-73.3 %). Median OS and 1-year survival rates were 21.0 (18.7-NR) and 70.8 % (63.9 %-780.6 %), and 14.1 (10.9-21.0) months and 54.9 % (42.8 %-70.4 %) for epithelioid and non-epithelioid PM subgroups, respectively. PFS was equal between the two subgroups. Grade 3-4 adverse events occurred in 23.3 % of patients and three deaths were treatment-related. CONCLUSIONS: For this unselected PM population, efficacy and safety outcomes compared favorably with CheckMate 743 trial results.

BACKGROUND: Post-operative whole breast radiotherapy for breast cancer (BC) may increase the risk of subsequent lung cancer (LC). The impact of radiotherapy intensification (boost) has not been specifically explored in this context. We investigated the role of radiation modalities on the development of subsequent LC among our patients treated by radiotherapy for localized BC. METHODS: All patients with a diagnosis of LC between 2000 and 2020 with a history of prior localized BC treated by surgery and post-operative radiotherapy were retrospectively reviewed. Primary endpoint was time to first diagnosis of LC after BC treatment with radiotherapy (RT). RESULTS: From 98 patients who developed subsequent LC after primary BC treated with post-operative RT, 38% of patients (n = 37) received an additional RT boost, and 46% (n = 45) received hormonal treatment post radiation. A total of 61% (n = 60) were smokers. With regards to LC characteristics, adenocarcinoma was the most frequent histology (68%, n = 66); 36% (n = 35) harbored at least 1 molecular alteration, 57% (n = 20) of them being amenable to targeted therapy. Median time to first diagnosis of LC was 6 years [1.7-28.4 yrs] in the whole cohort. In the subgroup of patients treated with boost this time was reduced to 4 years [1.8-20.8 years] compared to 8 years for patients without boost [1.7-28.4 yrs] (p = 0.007). Boost, smoking usage, endocrine therapy, and age <50 yrs old at BC radiation remained independent factors associated with shorter time to first diagnosis of LC after BC treatment. DISCUSSION: We report for the first time the potential impact of boost -part of BC radiation treatment- for BC on the risk of subsequent LC. The impact of low dose radiation on lung parenchyma could explain this phenomenon, but the underlying physiopathology is still under investigation. This work highlights the need for clinicians to identify patients at risk of developing faster subsequent thoracic malignancy after BC radiation, for implementing personalized surveillance.

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.

First-line therapy in advanced non-small-cell-lung-cancer (NSCLC) is based on chemotherapy except for patients with a tumor proportion score for programmed death ligand 1 (PD-L1) of 50% or greater, pembrolizumab is administrated. However, patients with somatic-EGFR-mutated tumors had usually been excluded from clinical applications of immune checkpoint inhibitors (ICIs). Germline-EGFR-mutated-patients are known to not respond to EGFR-Tyrosine-Kinase-inhibitors (TKIs). But what about germline EGFR mutations and response to ICIs? Herein, we describe the case of a long response to ICIs treatment in a complex metastatic NSCLC with co-occuring EGFR germline and KRAS somatic mutations, high PD-L1 score and a smoking history.

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 <1% (n = 31; HR, 0.71; 95% CI, 0.31-1.60; Pinteraction = 0.036). 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.

Introduction: Telehealth is taking an increasingly important part of medicine. This practice change is being accelerated by the pandemic linked to coronavirus disease 2019. Oncology is a medical specialty for which this paradigm shift is particularly relevant. Methods: We developed a survey aiming at evaluating the use of teleconsultation by physicians managing patients with lung cancer in France. The survey was available online from December 15, 2020, to February 10, 2021. Results: Answers were obtained from 142 clinicians (73.9% pneumologists, 18.3% medical oncologists, and 7.7% with another specialty), 129 (90.8%) of whom had already performed teleconsultation. Among those, 123 (95.3%) started after the coronavirus disease 2019 pandemic. In addition, 72.9% had a moderate usage of this tool (<10 teleconsultations/mo). The frequency of clinicians never using teleconsultation was higher in private practices (p = 0.029). The two clinical situations for which teleconsultation was frequently used were visits during treatment without imaging assessment (53.5%) and post-treatment surveillance (80.3%). Depending on the type of treatment received, the frequency of teleconsultation was variable. Lung cancer subtype also affected the clinician's practice. Indeed, 47.2% never proposed this tool for SCLC. Teleconsultation was considered to be of no contribution, a moderate contribution, a significant contribution, or a revolution of the clinical practice for 14.1%, 66.2%, 10.6%, and 2.1% of the respondents, respectively. The participants expected to decrease, stabilize, or increase their teleconsultation activity in 18.3%, 52.8%, and 23.2% of the cases, respectively. Conclusions: Most thoracic oncologists in France are using teleconsultation, mostly as an additional tool that should not replace the doctor-patient in-person relationship.
RESUMO
PURPOSE: Consolidation immunotherapy with the PD-L1 inhibitor durvalumab following concurrent chemoradiotherapy (cCRT) has shown a significant survival improvement and is now a standard of care in patients with unresectable stage III or non-operable non-small cell lung cancer (NSCLC). METHODS: In this early access program cohort, demographic, disease characteristics and safety data were collected for 576 patients from 188 centers, who received durvalumab 10 mg/kg intravenous infusion every 2 weeks, until disease progression or unacceptable toxicity or for a maximum of 12 months following cCRT. Durvalumab exposure data were available for 402 patients. RESULTS: Overall, 576 patients were included, 72.9% were men, median age 64.0 years, 52.3% had a stage IIIB disease. PD-L1 status captured in 445 (77%) patients was positive (48.1%), negative (32.6%), unknown (19.3%). At the end of cCRT, adverse events (AEs) all grade ≤ 2, were reported in 22.7% of patients, mainly esophagitis (6.3%). The main reasons of discontinuation were completion of the planned 12 months of consolidation treatment (42.1% patients), disease progression (28.6%) and adverse events (19.5%). Treatment completion was similar in PDL-1 positive and PDL-1 negative patients groups. 20.7% patients had a SAE drug reaction and 17.7% stopped treatment mainly due to SAE. ADR rate and early treatment discontinuation were higher in patients > 70 years old. Death due to AEs occurred in 7 patients, 2 had interstitial lung disease. CONCLUSION: Safety data with durvalumab consolidation after cCRT in a large cohort of patients with stage III NSCLC are reported in this real-life cohort. Consistent data were reported both in the PD-L1 positive and PD-L1 negative NSCLC patients in daily practice.

Over the last decade, the development of next-generation sequencing techniques has led to the molecular dismantlement of adult and pediatric sarcoma, with the identification of multiple gene fusions associated with specific subtypes and currently integrated into diagnostic classifications. In this report, we describe and discuss the identification of a novel EWSR1-UBP1 gene fusion in an adult patient presenting with multi-metastatic sarcoma. Extensive pathological, transcriptomic, and genomic characterization of this tumor in comparison with a cohort of different subtypes of pediatric and adult sarcoma revealed that this fusion represents a novel variant of spindle cell rhabdomyosarcoma with features of TFCP2-rearranged subfamily.

BACKGROUND: Stage IIIA/B-N2 is a very heterogeneous group of patients and accounts for one third of NSCLC at diagnosis. The best treatment strategy is established at a Multidisciplinary Tumor Board (MTB): surgical resection with neoadjuvant or adjuvant therapy versus definitive chemoradiation with immune checkpoint inhibitors consolidation. Despite the crucial role of MTBs in this complex setting, limited data is available regarding its performances and the reproducibility of the decision-making. METHODS: Using a large cohort of IIIA/B-N2 NSCLC patients, we described patient's characteristics and treatment strategies established at the initial MTB: with a "surgical strategy" group, for potentially resectable disease, and a "medical strategy" group for non-resectable patients. A third group consisted of patients who were not eligible for surgery after neoadjuvant treatment and switched from the surgical to the medical strategy. We randomly selected 30 cases (10 in each of the 3 groups) for a blinded re-discussion at a fictive MTB and analyzed the reproducibility and factors associated with treatment decision. RESULTS: Ninety-seven IIIA/B-N2 NSCLC patients were enrolled between June 2017 and December 2019. The initial MTB opted for a medical or a surgical strategy in 44% and 56% of patients respectively. We identified histology, tumor size and localization, extent of lymph node involvement and the presence of bulky mediastinal nodes as key decision-making factors. Thirteen patients were not eligible for surgical resection after neoadjuvant therapy and switched for a medical strategy. Overall concordance between the initial decision and the re-discussion was 70%. The kappa correlation coefficient was 0.43. Concordance was higher for patients with limited mediastinal node invasion. Survival did not appear to be impacted by conflicting decisions. CONCLUSIONS: Reproducibility of treatment decision-making for stage IIIA/B-N2 NSCLC patients at a MTB is moderate but does not impact survival.

INTRODUCTION: Severe acute respiratory syndrome coronavirus (SARS-CoV)-2 has spread worldwide in 2020 leading the World Health Organization to declare a pandemic. Patients with thoracic cancers have been reported at higher risk to develop severe disease, and die from COVID-19. In this setting, clinical practice recommendations for the management of patients were published. We report here how these guidelines were implemented in a routine practice setting. METHODS: We retrospectively collected the characteristics, treatment regimen and modification, as well as COVID-19 status and death for all patients with thoracic malignancies scheduled for an appointment at Institute Curie from March 23rd to April 17th 2020. RESULTS: A total of 339 patients were included. Treatment strategy was modified for a total of 110 (32 %) patients because of COVID-19; these modifications were in accordance with guidelines for 92 % of patients. The majority of dose modifications were related to immune checkpoint inhibitors, for which switch to flat dosing every 4-6 weeks was made. A total of 5 (1.5 %) patients were diagnosed with COVID-19 disease, 1 of whom died from disease complication. CONCLUSION: Our study provides a unique insight in the decision making for patients with thoracic malignancies in the setting of COVID-19 outbreak, showing how guidelines were implemented in the clinic, and what may be optimized in the clinical practice of thoracic oncology in the future.

Significant rational is available for specific targeting of PI3K/AKT/mTOR pathway in the treatment of non-small cell lung cancer (NSCLC). However, almost all clinical trials that have evaluated Pi3K pathway-based monotherapies/combinations did not observe an improvement of patient's outcome. The aim of our study was therefore to define combination of treatment based on the determination of predictive markers of resistance to the mTORC1 inhibitor RAD001/Everolimus. An in vivo study showed high efficacy of RAD001 in NSCLC Patient-Derived Xenografts (PDXs). When looking at biomarkers of resistance by RT-PCR study, three genes were found to be highly expressed in resistant tumors, i.e., PLK1, CXCR4, and AXL. We have then focused our study on the combination of RAD001 + Volasertib, a PLK1 inhibitor, and observed a high antitumor activity of the combination in comparison to each monotherapy; similarly, a clear synergistic effect between the two compounds was found in an in vitro study. Pharmacodynamics study demonstrated that this synergy was due to (1) tumor vascularization decrease, increase of the HIF1 protein expression and decrease of the intracellular pH, and (2) decrease of the Carbonic Anhydrase 9 (CAIX) protein that could not correct intracellular acidosis. In conclusion, all these preclinical data strongly suggest that the inhibition of mTORC1 and PLK1 proteins may be a promising therapeutic approach for NSCLC patients.
RESUMO
BACKGROUND: Immune checkpoint inhibitor (ICPi) rechallenge could represent an attractive option in non-small-cell lung cancer (NSCLC), yet no sufficient data supporting this strategy are available. This retrospective observational multicenter national study explored the efficacy of anti-programmed cell death 1 (PD-1)/programmed death ligand 1 (PD-L1) rechallenge in advanced NSCLC patients, looking for potential clinical features associated with greater outcomes. PATIENTS AND METHODS: We retrospectively collected data from 144 advanced NSCLC patients whose disease was rechallenged with ICPis after ≥ 12 weeks of discontinuation. The progression-free survival (PFS) and overall survival (OS) were calculated from first or second ICPi initiation to disease progression (PFS1 and PFSR, respectively), death, or last follow-up (OS1, OSR), respectively. RESULTS: The median (interquartile range) age was 63 (58-70) years. Most patients were male (67%) and smokers (87%). Most had adenocarcinomas (62%) and/or stage IV disease at diagnosis (66%). The best response at rechallenge was not associated with that under the first ICPi (P = 1.10-1). The median (95% confidence interval) PFS1 and PFSR were 13 (10-16.5) and 4.4 (3-6.5) months, respectively. The median (95% confidence interval) OS1 and OSR were 3.3 (2.9-3.9) and 1.5 (1.0-2.1) years, respectively. Longer PFSR and OSR were found in patients discontinuing first ICPi because of toxicity or clinical decision, those not receiving systemic treatment between the two ICPis, and those with good Eastern Cooperative Oncology Group performance status at rechallenge. Only performance status proved to affect outcomes at multivariate analysis. CONCLUSION: Patients discontinuing first ICPi because of toxicity or clinical decision, those able to maintain a treatment-free period, and those with good performance status may be potential candidates for rechallenge.

The aim of this study was to examine the association between physical health conditions and quality of life and functioning in private psychiatric inpatients. We sought to determine whether quality of life and functioning was poorer in individuals with physical comorbidity compared to those without. A quantitative correlational descriptive design was utilized. Seventy patients were included in sequential order within a week of admission to hospital. Participants completed the SF-36 survey, and the corresponding hospital records were audited. The STROBE guidelines were followed in the reporting of this research. The study found that 64.3% (45/70) of participants had one or more comorbid physical health conditions, primarily cardiovascular, respiratory, musculoskeletal, endocrine and medically unexplained conditions or syndromes. Chronic pain was experienced by 40% (28/70) of participants, and 47.6% (33/70) were found to be overweight or obese. Tobacco smoking and obesity were risk factors associated with physical comorbidity (P = 0.02 and P < 0.001, respectively). Quality of life and functioning were poorer in those with physical health conditions, particularly in the SF-36 domains of bodily pain, physical functioning and general health (P < 0.001, P = 0.003 and P = 0.005, respectively). Physical health conditions were largely prevalent, and quality of life and functioning were poorer in those with physical comorbidities. The implementation of clinical guidelines for the monitoring of physical health has been proposed as well as a dedicated physical health nursing role. Continuation of integrative programmes focusing on both physical and mental health may also benefit patients in this setting.

An original immuno-regulatory strategy against inflammatory bowel diseases based on the use of 28 kDa glutathione S-transferase (P28GST), a unique schistosome protein, was recently proposed. Improvement of intestinal inflammation occurs through restoration of the immunological balance between pro-inflammatory T-helper 1 (Th1) responses and both T-helper 2 (Th2) and regulatory responses. However, detailed mechanisms explaining how P28GST prevents colitis and promotes gut homeostasis remain unknown. Considering the complex interplay between the adaptive and innate immune system and the intestinal microbiota, we raised the question of the possible role of the microbial ecosystem in the anti-inflammatory effects mediated by the helminth-derived P28GST protein. We first analyzed, by 16S rRNA sequencing, the bacterial profiles of mice fecal microbiota at several time points of the P28GST-immunomodulation period prior to trinitrobenzene sulfonic acid (TNBS)-colitis. The influence of gut microbiota in the P28GST-mediated anti-inflammatory effects was then assessed by fecal microbiota transplantation experiments from P28GST-immunized mice to either conventional or microbiota depleted naïve recipient mice. Finally, the experimental data were supplemented by the temporal fecal microbiota compositions of P28GST-treated Crohn's disease patients from a pilot clinical study (NCT02281916). The P28GST administration slightly modulated the diversity and composition of mouse fecal microbiota while it significantly reduced experimental colitis in mice. Fecal microbiota transplantation experiments failed to restore the P28GST-induced anti-inflammatory effects. In Crohn's disease patients, P28GST also induced slight changes in their overall fecal bacterial composition. Collectively, these results provide key elements in both the anti-inflammatory mechanisms and the safe therapeutic use of immunomodulation with such promising helminth-derived molecules.

Objectives The efficacy of osimertinib in pretreated patients with advanced non-small cell lung cancer (NSCLC) harboring EGFR T790 M resistance mutation was demonstrated in clinical trials. However, data on efficacy of osimertinib in real world remain rare. Materials and methods This retrospective multicentric study analyzed T790M-positive advanced NSCLC patients enrolled in French early access program for osimertinib. Patients were pretreated with first- or second-generation EGFR tyrosine-kinase inhibitor and for a majority with chemotherapy. Primary endpoints were progression-free survival (PFS) and overall survival (OS) from osimertinib initiation. Results 205 patients (mean age, 69.5 years; female, 68.8%; adenocarcinoma, 97.5%, never-smokers, 71.5%) were analyzed. Osimertinib was used in second and third line in 18.0% and 82.0% of patients, respectively. Median PFS was 12.4 (95% CI, 10.1-15.1) months. In patients with and without cerebral metastasis, PFS was 9.7 (7.7-13.5) and 15.1 (12.0-17.1) months (p = 0.21), respectively. PFS in second and third line or more was 12.6 (6.7-17.5) and 12.4 (9.7-15.3) months, respectively. Median PFS in patients with EGFR exon 19 deletion and exon 21 mutation was 13.5 (10.1-16.0) and 9.7 (7.4-13.2) months, respectively (p = 0.049). Median OS since osimertinib initiation was 20.5 (16.9-24.3) months: 23.1 (18.6-27.8) and 18.0 (12.2-22.2) months in patients without and with cerebral metastasis (p = 0.11); 17.5 (11.6-27.8) and 21.7 (17.3-24.3) months as second or third line of treatment or more (p = 0.46), respectively. Median OS in patients with EGFR exon 19 deletion and exon 21 mutation was 23.1 (18.6-25.7) and 15.3 (11.6-21.7) months, respectively (p = 0.03). Osimertinib dosage was modified in 8.0% of patients and definitively discontinued for adverse events in 5.9%. Fifty patients benefited from rebiopsy (persistence of T790 M mutation, 44.7%; C797S mutation, 21.1%; cMET amplification, 8.0%). Conclusion In pretreated patients with T790M-mutated advanced NSCLC, the efficacy of osimertinib appears similar in real-world setting to that of clinical trials.

ALK rearrangement and EGFR/KRAS mutations constitute the primary biomarkers tested to provide targeted or nontargeted therapies in advanced nonsmall cell lung cancer (NSCLC) patients. Our objective was to assess the cost-effectiveness of biomarker testing for NSCLC.Between 2013 and 2014, 843 treatment-naive patients were prospectively recruited at 19 French hospitals into a longitudinal observational cohort study. Two testing strategies were compared, i.e. with "at least one biomarker status known" and "at least KRAS status known", in addition to "no biomarker testing" as the reference strategy. The Kaplan-Meier approach was employed to assess restricted mean survival time. Direct medical costs incurred by hospitals were estimated with regard to treatment, inpatient care and biomarker testing.Compared with "no biomarker testing", the "at least one biomarker status known" strategy yielded an incremental cost-effectiveness ratio of EUR13â230 per life-year saved, which decreased to EUR7444 per life-year saved with the "at least KRAS status known" testing strategy. In sensitivity analyses, biomarker testing strategies were less costly and more effective in 41% of iterations.In summary, molecular testing prior to treatment initiation proves to be cost-effective in advanced NSCLC management and may assist decision makers in defining conditions for further implementation of these innovations in general practice.

Venetoclax (formerly ABT-199) was recently approved in the United States for the treatment of patients who have relapsed or refractory chronic lymphocytic leukemia (CLL) with the 17p deletion. Venetoclax has demonstrated marked activity as monotherapy as well as in combination with cytotoxic chemotherapies, B-cell receptor inhibitors, and anti-CD20 monoclonal antibodies across the spectrum of CLL. The potency of venetoclax has been associated with a unique ability to induce deep (minimal residual disease-negative) complete remissions that appear to be durable. Its toxicity profile includes manageable hematologic toxicities, as well as the potential for tumor lysis syndrome. Here, we review the BCL-2 pathway and the mechanism of action of BCL-2 inhibitors, the activity and safety profile of venetoclax, and the practical application of venetoclax in the management of patients with CLL.
