Anti-coagulant Treatment of Cancer-Associated Thrombosis in Frail Patients: Impact of Frailties on the Management of Drug-Drug Interactions.

Low molecular weight heparins (LMWH) and anti-Xa direct oral anti-coagulants (DOACs) are recommended for the long-term treatment of cancer-associated thrombosis (CAT) based on well-documented randomised controlled trials. Anti-Xa DOACs are viewed as a first choice for the treatment of patients with CAT. A large number of drug-drug interactions have been reported between DOACs and chemotherapy drugs, modifying circulating levels of DOAC leading to fears of increased bleeding risks or thrombotic recurrence. Progresses in anti-neoplastic therapies have improved the prognosis and the survival, thus increasing the prevalence of frail patients with cancer. However, since frailties tend to be excluded from large trials due to multiple co-morbidities, current guidelines are not fully applicable to this population. The management of these frail patients with CAT is particularly complex and requires a risk assessment on a case-by-case basis with specific focus on cancer, patient-related risk factors and drug-drug interactions. In this brief review we have identified age, co-morbidities and co-medications as key factors of frailty that require careful attention and we have developed a therapeutic decision algorithm to help clinicians optimising the use of anti-coagulants in patients with cancer with CAT, especially in case of anti-Xa DOACs concomitant medications. With the evaluation of the bleeding risk according to the type of cancer, and anticipating drug-drug interactions intensity, taking into account patient frailties allows the optimisation of the anti-coagulant choice. A systematic collaboration between oncologists, vascular pathology specialists and pharmacists is warranted to ensure an optimal patient management. Clinical studies are needed to determine the real impact of these interactions.

High flow nasal oxygen in frail COVID-19 patients hospitalized in intermediate care units and non-eligible to invasive mechanical ventilation.

BACKGROUND: In COVID-19 patients, older age (sixty or older), comorbidities, and frailty are associated with a higher risk for mortality and invasive mechanical ventilation (IMV) failure. It therefore seems appropriate to suggest limitations of care to older and vulnerable patients with severe COVID-19 pneumonia and a poor expected outcome, who would not benefit from invasive treatment. HFNO (high flow nasal oxygen) is a non-invasive respiratory support device already used in de novo acute respiratory failure. The main objective of this study was to evaluate the survival of patients treated with HFNO outside the ICU (intensive care unit) for a severe COVID-19 pneumonia, otherwise presenting limitations of care making them non-eligible for IMV. Secondary objectives were the description of our cohort and the identification of prognostic factors for HFNO failure. METHODS: We conducted a retrospective cohort study. We included all patients with limitations of care making them non-eligible for IMV and treated with HFNO for a severe COVID-19 pneumonia, hospitalized in a COVID-19 unit of the pulmonology department of Lyon Sud University Hospital, France, from March 2020 to March 2021. Primary outcome was the description of the vital status at day-30 after HFNO initiation, using the WHO (World Health Organization) 7-points ordinal scale. RESULTS: Fifty-six patients were included. Median age was 83 years [76.3-87.0], mean duration for HFNO was 7.5 days, 53% had a CFS score (Clinical Frailty Scale) >4. At day-30, 73% of patients were deceased, one patient (2%) was undergoing HFNO, 9% of patients were discharged from hospital. HFNO failure occurred in 66% of patients. Clinical signs of respiratory failure before HFNO initiation (respiratory rate >30/min, retractions, and abdominal paradoxical breathing pattern) were associated with mortality (p = 0.001). CONCLUSIONS: We suggest that HFNO is an option in non-ICU skilled units for older and frail patients with a severe COVID-19 pneumonia, otherwise non-suitable for intensive care and mechanical ventilation. Observation of clinical signs of respiratory failure before HFNO initiation was associated with mortality.

Improved Survival Outcomes in Patients With MET-Dysregulated Advanced NSCLC Treated With MET Inhibitors: Results of a Multinational Retrospective Chart Review.

BACKGROUND: We evaluated the disease and patient characteristics, treatment, and MET testing patterns, predictive biomarkers and survival outcomes in patients with MET-dysregulated metastatic non-small-cell lung cancer (NSCLC) in a real-world setting. PATIENTS AND METHODS: This was a multinational, retrospective, noninterventional chart review study. Data from medical records of patients with advanced/metastatic EGFR wild-type, MET-dysregulated NSCLC (December 2017-September 2018) were abstracted into electronic data collection forms. RESULTS: Overall, 211 patient charts were included in this analysis; 157 patients had MET exon 14 skipping mutations (METex14; with or without concomitant MET amplification) and 54 had MET amplification only. All patients were tested for METex14, whereas MET amplification was evaluated in 168 patients. No overlap was reported between MET dysregulation and ALK, ROS1 or RET rearrangements, or HER2 exon 20 insertions. Overall, 56 of 211 patients (26.5%) received MET inhibitor (METi) therapy in any treatment-line setting (31.2% in the METex14 cohort; 13% in the MET-amplified only cohort). In the METex14 cohort, median OS in patients receiving METi was 25.4 months versus 10.7 months in patients who did not (HR [95% CI]: 0.532 [0.340-0.832]; P = .0055). In the MET-amplified only cohort, median OS was 20.6 months in patients treated with METi compared with 7.6 months in those without METi (HR [95% CI]: 0.388 [0.152-0.991]; P = .0479). CONCLUSIONS: MET alterations in NSCLC typically occur in the absence of other oncogenic driver mutations and are associated with poor survival outcomes. Notably, METi therapies are associated with improved survival outcomes in patients with MET-dysregulated NSCLC.

Cost-effectiveness analysis of atezolizumab as adjuvant treatment of patients with stage II-IIIA non-small cell lung cancer, PD-L1+≥50% of tumor cells in France: A modeling study.

INTRODUCTION: The objective of this study was to assess the cost-effectiveness of atezolizumab versus best supportive care (BSC) as adjuvant treatment following resection and platinum-based chemotherapy for patients with stage II-IIIA non-small cell lung cancer (NSCLC) whose tumours have a programmed death-ligand 1 (PD-L1) expression ≥ 50% of tumour cells and excluding those with ALK/EGFR mutations, from a French collective perspective. MATERIAL AND METHODS: A five state Markov model over a 20-year time horizon was considered, including disease-free survival (DFS1) from IMpower010 trial, three progression states (locoregional recurrence, first and second-line metastatic recurrence) and death. Utilities, quality-adjusted life year (QALY) decrements associated to adverse events, costs, resource use, and transition probabilities were considered in the model. These inputs were sourced from IMpower010 trial, literature, and clinical experts' opinion. Model uncertainty was assessed through deterministic, probabilistic sensitivity analyses and scenario analyses. RESULTS: Atezolizumab was associated with a QALY gain of 1.662, mainly driven by additional time spent in the DFS state, and a life-year gain of 2.112 years. The incremental cost-effectiveness ratio (ICER) for atezolizumab versus BSC was €21,348/QALY gained. The sensitivity analyses highlighted that uncertainty within the model had limited impact on results. Changing the DFS survival curves to other plausible distributions produced ICERs below €20,000/QALY. Introducing an increasing proportion of cured patients (91.5%) from year two to year five reduced the ICER to €13,083/QALY, while including a loss of efficacy at year two in the atezolizumab treatment arm increased the ICER to €33,755/QALY. DISCUSSION: Atezolizumab as adjuvant treatment in stage II-IIIA NSCLC resected patients with PDL1 ≥ 50% and without ALK/EGFR mutations has a lower ICER than other oncology drugs in France and a similar ICER to other adjuvant treatment in oncology.

G-CSF filgrastim biosimilar-Sandoz reduces the incidence of febrile neutropenia in patients receiving chemotherapy regimens with rest periods not exceeding 14 days: A French, multicenter, prospective, non-interventional study.

PURPOSE: The objective of this study was to describe filgrastim biosimilar-Sandoz modalities of use in patients receiving cytotoxic chemotherapy regimens with a rest period of ≤14 days and to investigate the incidence of febrile neutropenia (FN) in routine clinical practice. METHODS: This was a French, multicenter, prospective and descriptive, non-interventional study including patients with breast, lung, gastrointestinal cancer or a lymphoma initiating filgrastim biosimilar-Sandoz treatment and in the context of cytotoxic chemotherapy with a rest period not exceeding 14 days. Data were collected during two routine clinical visits on the modalities of use of filgrastim biosimilar-Sandoz, on the incidence of neutropenia events and on adverse events. RESULTS: Between November 2015 and June 2018, 1080 patients were enrolled in the study in 129 centers. Overall, 941 patients were evaluable for efficacy and 937 for safety. Of the 941 patients, 84.8% had a solid tumor and 15.2% had a lymphoid hemopathy. Filgrastim biosimilar-Sandoz was prescribed as primary prophylaxis in 74.0% of the patients and as secondary prophylaxis in 22.4% of the patients. FN was reported in 1.5% of patients with a solid tumor and 12.6% of patients with a lymphoma. A chemotherapy relative dose intensity of over 85% with regard to the reference dose was achieved by more than 80% of the patients in all tumor localizations. CONCLUSIONS: The study showed that filgrastim biosimilar-Sandoz is safe to use and effective in preventing FN and in allowing to maintain the dose intensity of chemotherapy.

Intravenous route for folate supplementation in a patient with celiac disease treated by pemetrexed-based chemotherapy for non-small-cell lung cancer.

INTRODUCTION: Oral folic acid supplementation is essential for patients treated with pemetrexed, to prevent the risk of severe hematologic toxicity. In case of intestinal absorption disorder, no recommendations exist for intravenous folic acid supplementation. CASE REPORT: We describe a 74-year-old patient with multimetastatic non-small-cell lung adenocarcinoma, receiving first-line chemotherapy with carboplatin AUC5, pemetrexed 500 mg/m2 and pembrolizumab 200 mg intravenously every 3 weeks. The patient presented neglected celiac disease, resulting in malabsorption syndrome with iron and folic acid deficiency. The question was how to administer folic acid supplementation during the pemetrexed-based chemotherapy. MANAGEMENT AND OUTCOMES: Intravenous injection of 200 mg levoleucovorin on day 1 of cycle 1 of pemetrexed-based chemotherapy was administered and well tolerated. During the second cycle, the levoleucovorin perfusion was not renewed by omission. The patient was hospitalized for 7 days because of febrile aplasia. Piperacillin-tazobactam was started, and then switched to amoxicillin-clavulanate plus ciprofloxacin. After this episode of post-chemotherapy febrile aplasia, it was decided to systematically supplement the patient with intravenous levoleucovorin, with blood folate concentration monitoring at each cycle. At 16 months after start of treatment, the patient was in complete remission, indicating that the immune-chemotherapy was effective, with no further febrile neutropenia. DISCUSSION/CONCLUSION: This case report highlights intravenous levoleucovorin supplementation as an alternative to oral folic acid if needed during pemetrexed-antifolate-based chemotherapy.

Chest CT scan plus x-ray versus chest x-ray for the follow-up of completely resected non-small-cell lung cancer (IFCT-0302): a multicentre, open-label, randomised, phase 3 trial.

BACKGROUND: Even after resection of early-stage non-small-cell lung cancer (NSCLC), patients have a high risk of developing recurrence and second primary lung cancer. We aimed to assess efficacy of a follow-up approach including clinic visits, chest x-rays, chest CT scans, and fibre-optic bronchoscopy versus clinical visits and chest x-rays after surgery for resectable NSCLC. METHODS: In this multicentre, open-label, randomised, phase 3 trial (IFCT-0302), patients aged 18 years or older and after complete resection of pathological stage I-IIIA NSCLC according to the sixth edition of the TNM classification were enrolled within 8 weeks of resection from 122 hospitals and tertiary centres in France. Patients were randomly assigned (1:1) to CT-based follow-up (clinic visits, chest x-rays, thoraco-abdominal CT scans, and fibre-optic bronchoscopy for non-adenocarcinoma histology) or minimal follow-up (visits and chest x-rays) after surgery for NSCLC, by means of a computer-generated sequence using the minimisation method. Procedures were repeated every 6 months for the first 2 years and yearly until 5 years. The primary endpoint was overall survival analysed in the intention-to-treat population. Secondary endpoints, also analysed in the intention-to-treat population, included disease-free survival. This trial is registered with ClinicalTrials.gov, NCT00198341, and is active, but not enrolling. FINDINGS: Between Jan 3, 2005, and Nov 30, 2012, 1775 patients were enrolled and randomly assigned to a follow-up group (888 patients to the minimal follow-up group; 887 patients to the CT-based follow-up group). Median overall survival was not significantly different between follow-up groups (8·5 years [95% CI 7·4-9·6] in the minimal follow-up group vs 10·3 years [8·1-not reached] in the CT-based follow-up group; adjusted hazard ratio [HR] 0·95, 95% CI 0·83-1·10; log-rank p=0·49). Disease-free survival was not significantly different between follow-up groups (median not reached [95% CI not estimable-not estimable] in the minimal follow-up group vs 4·9 [4·3-not reached] in the CT-based follow-up group; adjusted HR 1·14, 95% CI 0·99-1·30; log-rank p=0·063). Recurrence was detected in 246 (27·7%) of 888 patients in the minimal follow-up group and in 289 (32·6%) patients of 887 in the CT-based follow-up group. Second primary lung cancer was diagnosed in 27 (3·0%) patients in the minimal follow-up group and 40 patients (4·5%) in the CT-based follow-up group. No serious adverse events related to the trial procedures were reported. INTERPRETATION: The addition of thoracic CT scans during follow-up, which included clinic visits and chest x-rays after surgery, did not result in longer survival among patients with NSCLC. However, it did enable the detection of more cases of early recurrence and second primary lung cancer, which are more amenable to curative-intent treatment, supporting the use of CT-based follow-up, especially in countries where lung cancer screening is already implemented, alongside with other supportive measures.

Comprehensive Genome Profiling in Patients With Metastatic Non-Small Cell Lung Cancer: The Precision Medicine Phase II Randomized SAFIR02-Lung/IFCT 1301 Trial.

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.

Tailoring maintenance chemotherapy upon response to induction chemotherapy as compared with pemetrexed continuation maintenance in advanced non-squamous NSCLC patients: Results of the IFCT-GFPC-1101 multicenter randomized phase III trial.

BACKGROUND: Benefit from maintenance in advanced non-squamous non-small cell lung cancer (NS-NSCLC) might favor switch maintenance after disease stabilization (SD) and continuation after objective response (OR). This trial assessed a maintenance strategy conditioned by response to cisplatin-gemcitabine (CG) with G continuation for patients with OR or switch to pemetrexed (P) for patients with SD as compared with a control arm based on the Paramount regimen. METHODS: Eligibility criteria: age 18-70 years, ECOG PS 0-1, untreated stage IV NS-NSCLC without EGFR or ALK alteration, ineligibility to bevacizumab. Patients were randomized 1:1 to receive either CG (4 cycles) followed by G maintenance in case of OR followed by P at progression, or switch to P for patients with SD, or 4 cycles of CP followed by P (control arm). Primary endpoint: overall Survival. RESULTS: Between 2012 and 2016, 932 patients were randomized (CG: 467, CP: 465) with well-balanced characteristics. 257 patients (56.7%) in the CG arm received maintenance (G: 142, P: 113) versus 277 patients (59.7%) in the CP arm. Median number of maintenance cycles was 5 for G and P (CG induction) and 4 for P (CP induction). OS adjusted HR was 0.97 (95% CI 0.84, 1.13; p = 0.71) with a median of 10.9 months (CG) versus 10.4 (CP). HR for PFS was 0.95 (95% CI 0.83, 1.09; p = 0.45) with a median of 4.8 months for CG versus 4.5 for CP. Safety profile was as expected. CONCLUSIONS: Adapting maintenance strategy according to response to induction chemotherapy does not improve patient outcome. CLINICAL TRIAL INFORMATION: NCT01631136.

Phase 2 Study of Dabrafenib Plus Trametinib in Patients With BRAF V600E-Mutant Metastatic NSCLC: Updated 5-Year Survival Rates and Genomic Analysis.

INTRODUCTION: Dabrafenib plus trametinib was found to have robust antitumor activity in patients with BRAF V600E-mutant metastatic NSCLC (mNSCLC). We report updated survival analysis of a phase 2 study (NCT01336634) with a minimum of 5-year follow-up and updated genomic data. METHODS: Pretreated (cohort B) and treatment-naive (cohort C) patients with BRAF V600E-mutant mNSCLC received dabrafenib 150 mg twice daily and trametinib 2 mg once daily. The primary end point was investigator-assessed overall response rate per Response Evaluation Criteria in Solid Tumors version 1.1. Secondary end points were duration of response, progression-free survival, overall survival, and safety. RESULTS: At data cutoff, for cohorts B (57 patients) and C (36 patients), the median follow-up was 16.6 (range: 0.5-78.5) and 16.3 (range: 0.4-80) months, overall response rate (95% confidence interval [CI]) was 68.4% (54.8-80.1) and 63.9% (46.2-79.2), median progression-free survival (95% CI) was 10.2 (6.9-16.7) and 10.8 (7.0-14.5) months, and median overall survival (95% CI) was 18.2 (14.3-28.6) and 17.3 (12.3-40.2) months, respectively. The 4- and 5-year survival rates were 26% and 19% in pretreated patients and 34% and 22% in treatment-naive patients, respectively. A total of 17 patients (18%) were still alive. The most frequent adverse event was pyrexia (56%). Exploratory genomic analysis indicated that the presence of coexisting genomic alterations might influence clinical outcomes in these patients; however, these results require further investigation. CONCLUSIONS: Dabrafenib plus trametinib therapy was found to have substantial and durable clinical benefit, with a manageable safety profile, in patients with BRAF V600E-mutant mNSCLC, regardless of previous treatment.

The Effect of Foot Reflexology on Chemotherapy-Induced Nausea and Vomiting in Patients With Digestive or Lung Cancer: Randomized Controlled Trial.

BACKGROUND: Cancer is a chronic disease with an incidence of 24.5 million and 9.6 million deaths worldwide in 2017. Lung and colorectal cancer are the most common cancers for both sexes and, according to national and international recommendations, platinum-based chemotherapy is the reference adjuvant treatment. This chemotherapy can be moderately to highly emetogenic. Despite antiemetic therapy, chemotherapy-induced nausea and vomiting (CINV) may persist. Moreover, cancer patients are increasingly interested in alternative and complementary medicines and have expressed the desire that nonpharmacological treatments be used in hospitals. Among alternative and complementary medicines, foot reflexology significantly decreases the severity of CINV in patients with breast cancer. OBJECTIVE: The primary aim of this study was to assess the benefits of foot reflexology as a complement therapy to conventional treatments regarding the severity of acute CINV in patients with digestive or lung cancer. The secondary objectives assessed were the frequency and severity of delayed CINV, quality of life, anxiety, and self-esteem. METHODS: This study was conducted between April 2018 and April 2020 in the Hospices Civils de Lyon, France. This was an open-label randomized controlled trial. Participants were randomized into two groups: the intervention group (ie, conventional care with foot reflexology; n=40) and the control group (ie, conventional care without foot reflexology; n=40). Foot reflexology sessions (30 minutes each) were performed on outpatients or inpatients. Eligible participants were patients with lung or digestive cancer with an indication for platinum-based chemotherapy. RESULTS: The severity of acute nausea and vomiting was assessed with a visual analog scale during the second cycle of chemotherapy. A significant increase of at least 2 points was observed for the control group (7/34, 21%; P=.001). Across all cycles, the foot reflexology group showed a trend toward less frequent delayed nausea (P=.28), a significantly less frequent consumption of antiemetic drugs (P=.04), and no significant difference for vomiting (P=.99); there was a trend toward a perception of stronger severity for delayed nausea in the control group (P=.39). Regarding quality of life and anxiety, there was no significant difference between the intervention group and the control group (P=.32 and P=.53, respectively). CONCLUSIONS: This study's results indicate that foot reflexology provides significantly better management of acute nausea severity and decreased consumption of antiemetic drugs in patients with lung or digestive cancer. In order to fulfill patients' desires to use nonpharmacological treatments and complementary and alternative medicines in hospitals, foot reflexology could be provided as a complementary intervention to conventional antiemetic drugs. Foot reflexology did not result in adverse effects. To assess the benefits of foot reflexology in routine practice, a larger study with several health care centers would be needed with a cluster randomized controlled trial.

Standardized vs peer-played patients for learning how to break bad news in lung cancer: A prospective crossover study.

CONTEXT: Residents in respiratory medicine are often confronted with breaking bad news to patients. In communication skill training, a recurring question is whether to use standardized or peer-played patients for simulation METHODS: In this prospective single-center crossover study in pulmonology residents, a range of scenarios were performed during training sessions using standardized or peer-played patients. The aim was to assess whether patient type did alter the quality of the role-play. The residents completed post-scenario questionnaires about the role-play of each scenario, but also pre- and post-session questionnaires about their perception of the effectiveness of both modalities, and pre- and post-testing questionnaires about the psychological impact of the training. RESULTS: Collectively, 4 scenarios were performed 52 times and evaluated 208 times by 52 residents. The use of standardized patients appeared to improve the quality of the patient role (8.8 ± 1.0 vs. 8.3 ± 1.1; p = 0.001) and the general quality of role-play (8.8 ± 1.0 vs. 8.2 ± 0.9; p = 0.008), without affecting the quality of the physician role played by the resident. There were no significant differences between standardized and peer-played patients regarding learning interest or psychological impact. Regardless of the modality, the training sessions did appear to significantly affect the residents' evaluations of their ability to break bad news to patients (5.7 ± 1.1 vs. 7.4 ± 1.1; p < 10-4). CONCLUSION: Our results did not point to a superiority of either of these modalities for learning how to break bad news. Both may be used, depending on the local resources.

Tobacco use and related behaviors among staff and students in a university hospital: A large cross-sectional survey.

INTRODUCTION: Smoking prevalence in the overall population in France was 27% in 2017. There are few data about smoking prevalence in hospital workers. The aim of this study was to assess prevalence of current smoking in student and staff populations at Lyon University Hospital. Secondary objectives were to identify main variables associated with current smoking and willingness to quit. METHODS: We designed a single center, cross-sectional survey, using printed questionnaires. During one day, all registered staff and students were surveyed. We used optical reading to extract information from questionnaires. We performed univariate and multivariate analysis adjusted on most relevant factors. RESULTS: We analyzed 9712 questionnaires. The participating rates were high: 40.6% in the student cohort and 51.5% in the staff cohort. The proportion of current cigarette users was 26% in students and 25% in staff. In multivariate analysis, current smoking was significantly associated with: younger age, male sex, occupation type (e.g. logistical staff, and paramedical students), overnight work, and e-cigarette use. Among smokers, 53% reported a willingness to quit. In multivariate analysis, number of quit attempts, and feeling symptoms from tobacco were associated with willingness to quit. CONCLUSIONS: Current smoking is less frequent in our cohorts of hospital staff and students than in the general French population. However, there are deep disparities in current smoking prevalence underlining a heterogeneous population. Among smokers, the majority reported a willingness to quit and some predictive factors may help to target this audience.

Investigating the Impact of Immune-Related Adverse Events, Glucocorticoid Use and Immunotherapy Interruption on Long-Term Survival Outcomes.

It remains unclear whether immune-related adverse events (irAEs) and glucocorticoid use could impact long-term outcomes in patients treated for solid tumors with immune checkpoint inhibitors (ICI). All patients treated with a single-agent ICI for any advanced cancer were included in this retrospective unicentric study. The objectives were to assess the impact of grade ≥3 irAEs, glucocorticoid use and the interruption of immunotherapy on progression-free survival (PFS) and overall survival (OS). In this 828-patient cohort, the first occurrence of grade ≥3 irAEs had no significant impact on PFS or OS. Glucocorticoid administration for the irAEs was associated with a significantly shorter PFS (adjusted HR 3.0; p = 0.00040) and a trend toward shorter OS. ICI interruption was associated with a significantly shorter PFS (adjusted HR 3.5; p < 0.00043) and shorter OS (HR 4.5; p = 0.0027). Glucocorticoid administration and ICI interruption were correlated. In our population of patients treated with single agent ICI, grade ≥3 irAEs did not impact long-term outcomes. However, the need for glucocorticoids and the interruption of immunotherapy resulted in poorer long-term outcomes. The impact of grade ≥3 irAEs reported in other studies might then be explained by the management of the irAEs.

First-line nivolumab plus ipilimumab combined with two cycles of chemotherapy in patients with non-small-cell lung cancer (CheckMate 9LA): an international, randomised, open-label, phase 3 trial.

BACKGROUND: First-line nivolumab plus ipilimumab has shown improved overall survival in patients with advanced non-small-cell lung cancer (NSCLC). We aimed to investigate whether the addition of a limited course (two cycles) of chemotherapy to this combination would further enhance the clinical benefit. METHODS: This randomised, open-label, phase 3 trial was done at 103 hospitals in 19 countries. Eligible patients were aged 18 years or older with treatment-naive, histologically confirmed stage IV or recurrent NSCLC, and an Eastern Cooperative Oncology Group performance status of 0-1. Patients were randomly assigned (1:1) by an interactive web response system via permuted blocks (block size of four) to nivolumab (360 mg intravenously every 3 weeks) plus ipilimumab (1 mg/kg intravenously every 6 weeks) combined with histology-based, platinum doublet chemotherapy (intravenously every 3 weeks for two cycles; experimental group), or chemotherapy alone (every 3 weeks for four cycles; control group). Randomisation was stratified by tumour histology, sex, and PD-L1 expression. The primary endpoint was overall survival in all randomly assigned patients. Safety was analysed in all treated patients. Results reported here are from a pre-planned interim analysis (when the study met its primary endpoint) and an exploratory longer-term follow-up analysis. This study is active but no longer recruiting patients, and is registered with ClinicalTrials.gov, number NCT03215706. FINDINGS: Between Aug 24, 2017, and Jan 30, 2019, 1150 patients were enrolled and 719 (62·5%) randomly assigned to nivolumab plus ipilimumab with two cycles of chemotherapy (n=361 [50%]) or four cycles of chemotherapy alone (n=358 [50%]). At the pre-planned interim analysis (median follow-up 9·7 months [IQR 6·4-12·8]), overall survival in all randomly assigned patients was significantly longer in the experimental group than in the control group (median 14·1 months [95% CI 13·2-16·2] vs 10·7 months [9·5-12·4]; hazard ratio [HR] 0·69 [96·71% CI 0·55-0·87]; p=0·00065). With 3·5 months longer median follow-up (median 13·2 months [IQR 6·4-17·0]), median overall survival was 15·6 months (95% CI 13·9-20·0) in the experimental group versus 10·9 months (9·5-12·6) in the control group (HR 0·66 [95% CI 0·55-0·80]). The most common grade 3-4 treatment-related adverse events were neutropenia (in 24 [7%] patients in the experimental group vs 32 [9%] in the control group), anaemia (21 [6%] vs 50 [14%]), diarrhoea (14 [4%] vs two [1%]), increased lipase (22 [6%] vs three [1%]), and asthenia (tjree [1%] vs eight [2%]). Serious treatment-related adverse events of any grade occurred in 106 (30%) patients in the experimental group and 62 (18%) in the control group. Seven (2%) deaths in the experimental group (acute kidney failure, diarrhoea, hepatotoxicity, hepatitis, pneumonitis, sepsis with acute renal insufficiency, and thrombocytopenia; one patient each) and six (2%) deaths in the control group (anaemia, febrile neutropenia, pancytopenia, pulmonary sepsis, respiratory failure, and sepsis; one patient each) were treatment related. INTERPRETATION: Nivolumab plus ipilimumab with two cycles of chemotherapy provided a significant improvement in overall survival versus chemotherapy alone and had a favourable risk-benefit profile. These data support this regimen as a new first-line treatment option for patients with advanced NSCLC. FUNDING: Bristol Myers Squibb.

Circulating Tumor DNA as a Prognostic Determinant in Small Cell Lung Cancer Patients Receiving Atezolizumab.

BACKGROUND: The IFCT-1603 trial evaluated atezolizumab in small cell lung cancer (SCLC). The purpose of the present study was to determine whether circulating tumor DNA (ctDNA), prospectively collected at treatment initiation, was associated with the prognosis of SCLC, and whether it identified patients who benefited from atezolizumab. METHODS: 68 patients were included in this study: 46 patients were treated with atezolizumab and 22 with conventional chemotherapy. Circulating DNA was extracted from plasma and NGS (Next Generation Sequencing) looked for mutations in the TP53, RB1, NOTCH1, NOTCH2, and NOTCH3 genes. ctDNA was detectable when at least one somatic mutation was identified, and its relative abundance was quantified by the variant allele fraction (VAF) of the most represented mutation. RESULTS: We found that 49/68 patients (70.6%) had detectable baseline ctDNA. The most frequently identified mutations were TP53 (32/49; 65.3%) and RB1 (25/49; 51.0%). Patients with detectable ctDNA had a significantly lower disease control rate at week 6 compared with patients with no detectable ctDNA, regardless of the nature of the treatment. Detection of ctDNA was associated with a poor OS prognosis. The detection of ctDNA at a relative abundance greater than the median value was significantly associated with poor overall survival (OS) and progression free survival (PFS). Interestingly, the benefit in overall survival (OS) associated with low ctDNA was more pronounced in patients treated with atezolizumab than in patients receiving chemotherapy. Among patients whose relative ctDNA abundance was below the median, those treated with atezolizumab tended to have higher OS than those in the chemotherapy arm. CONCLUSION: ctDNA is strongly associated with the prognosis of SCLC patients treated with second-line immunotherapy. Its analysis seems justified for future SCLC clinical trials.

Capmatinib in MET Exon 14-Mutated or MET-Amplified Non-Small-Cell Lung Cancer.

BACKGROUND: Among patients with non-small-cell lung cancer (NSCLC), MET exon 14 skipping mutations occur in 3 to 4% and MET amplifications occur in 1 to 6%. Capmatinib, a selective inhibitor of the MET receptor, has shown activity in cancer models with various types of MET activation. METHODS: We conducted a multiple-cohort, phase 2 study evaluating capmatinib in patients with MET-dysregulated advanced NSCLC. Patients were assigned to cohorts on the basis of previous lines of therapy and MET status (MET exon 14 skipping mutation or MET amplification according to gene copy number in tumor tissue). Patients received capmatinib (400-mg tablet) twice daily. The primary end point was overall response (complete or partial response), and the key secondary end point was response duration; both end points were assessed by an independent review committee whose members were unaware of the cohort assignments. RESULTS: A total of 364 patients were assigned to the cohorts. Among patients with NSCLC with a MET exon 14 skipping mutation, overall response was observed in 41% (95% confidence interval [CI], 29 to 53) of 69 patients who had received one or two lines of therapy previously and in 68% (95% CI, 48 to 84) of 28 patients who had not received treatment previously; the median duration of response was 9.7 months (95% CI, 5.6 to 13.0) and 12.6 months (95% CI, 5.6 to could not be estimated), respectively. Limited efficacy was observed in previously treated patients with MET amplification who had a gene copy number of less than 10 (overall response in 7 to 12% of patients). Among patients with MET amplification and a gene copy number of 10 or higher, overall response was observed in 29% (95% CI, 19 to 41) of previously treated patients and in 40% (95% CI, 16 to 68) of those who had not received treatment previously. The most frequently reported adverse events were peripheral edema (in 51%) and nausea (in 45%); these events were mostly of grade 1 or 2. CONCLUSIONS: Capmatinib showed substantial antitumor activity in patients with advanced NSCLC with a MET exon 14 skipping mutation, particularly in those not treated previously. The efficacy in MET-amplified advanced NSCLC was higher in tumors with a high gene copy number than in those with a low gene copy number. Low-grade peripheral edema and nausea were the main toxic effects. (Funded by Novartis Pharmaceuticals; GEOMETRY mono-1 ClinicalTrials.gov number, NCT02414139.).

Switch maintenance chemotherapy versus observation after carboplatin and weekly paclitaxel doublet chemotherapy in elderly patients with advanced non-small cell lung cancer: IFCT-1201 MODEL trial.

PURPOSE: Maintenance chemotherapy is a reasonable choice for patients with metastatic non-small cell lung carcinoma (NSCLC) not progressing after induction therapy with a platinum-based doublet. Nevertheless, there have been no studies dedicated to elderly patients. PATIENTS AND METHODS: We conducted a randomised trial in patients aged 70-89 years, with advanced NSCLC (with neither EGFR mutation nor ALK rearrangement), who had not progressed after four cycles of monthly carboplatin and weekly paclitaxel in order to compare maintenance with either pemetrexed (500 mg/m2 d1, 22) in patients with non-squamous cell carcinoma or gemcitabine (1,150 mg/m2 d1, 8, 22) in squamous cell carcinoma to simple observation. The patients were required to have a performance status (PS) 0-2, mini-mental score >23, and creatinine clearance ≥45 mL/min. The primary end-point was overall survival (OS). RESULTS: 632 patients were enrolled from May 2013 to October 2016. Of the 328 (52.3%) patients randomised after induction therapy, 166 patients were assigned to the observation arm, versus 162 to the switch maintenance arm, 119 of whom received pemetrexed and 43 gemcitabine. The median OS from randomisation was 14.1 months (95% confidence interval [CI]: 12.0-17.0) in the observation arm and 14 months (95% CI: 10.9-16.9) in the maintenance arm (p = 0.72). The median progression-free survival (PFS) from randomisation was 2.7 months (95% CI: 2.6-3.1) in the observation arm versus 5.7 months (95% CI: 4.8-7.1) in the maintenance arm (p < 0.001). CONCLUSION: Switch maintenance therapy significantly prolonged PFS but not OS and, thus, should not be proposed to elderly patients with advanced NSCLC.

The Effects of Foot Reflexology on Chemotherapy-Induced Nausea and Vomiting in Patients with Digestive System or Lung Cancer: Protocol for a Randomized Controlled Trial.

BACKGROUND: The side effects of chemotherapy, specifically chemotherapy-induced nausea and vomiting, are a concern for patients. To relieve these side effects, antiemetic drugs are recommended. However, some patients report that these drugs are not sufficiently effective. Moreover, patients with chronic disease, including cancer, are increasingly interested in complementary and alternative medicines, and express the desire for nonpharmacological treatments to be used in hospitals. Foot reflexology is a holistic approach that is reported to significantly reduce the severity of chemotherapy-induced nausea and vomiting in patients with breast cancer. Some of the chemotherapy treatments for patients with lung and digestive system cancer are moderately or highly emetic. OBJECTIVE: The primary objective of this study is to assess the benefits of foot reflexology, together with conventional treatments, on the severity and frequency of chemotherapy-induced nausea and vomiting in patients with lung or digestive system cancer. The secondary objectives to be assessed are quality of life, anxiety, and self-esteem. METHODS: This study is an open-label randomized controlled trial conducted over 22 months (18 months intervention and 4 months follow-up). Eligible participants are patients with a lung or digestive system cancer with an indication for platinum-based chemotherapy. Participants are randomized into two groups: conventional care with foot reflexology and conventional care without foot reflexology. Foot reflexology sessions (30 minutes) are performed on an outpatient or inpatient basis. It was estimated that 40 participants per group will be required. The benefits of foot reflexology will be assessed by comparing the relative change in the severity of nausea and vomiting, as assessed by a visual analogue scale, and the frequency of these side effects between the two groups. The secondary objectives will be assessed with the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire; Hospital and Anxiety Depression Scale; and Body Image Questionnaire. RESULTS: This study was approved by the regional ethics committee (Île de France X CPP) on April 3, 2018 (No. ID RCB 2018-A00571-54). Enrollment started in June 2018. Data analysis will be performed during the second quarter of 2020 and results will be published in the last quarter of 2020. CONCLUSIONS: The lack of knowledge regarding the efficacy and safety of foot reflexology limits oncologists to recommend it for this use. This study will provide evidence of the benefits of foot reflexology. If efficacy is confirmed, foot reflexology may be a promising complement to conventional antiemetic drugs.

Randomized Phase II Trial Evaluating Treatment with EGFR-TKI Associated with Antiestrogen in Women with Nonsquamous Advanced-Stage NSCLC: IFCT-1003 LADIE Trial.

PURPOSE: The incidence of lung cancer has dramatically increased in women. Preclinical data have suggested that combining EGFR-tyrosine kinase inhibitor (TKI) with an antiestrogen may overcome resistance to EGFR-TKI. PATIENTS AND METHODS: The IFCT-1003 LADIE trial was a 2 × 2 arms parallel open-label randomized phase II trial. EGFR-TKI-naïve postmenopausal women with advanced lung cancer were treated with gefitinib (G) versus gefitinib + fulvestrant (G+F) in the EGFR-mutated group (EGFR+) or with erlotinib (E) versus erlotinib + fulvestrant (E+F) in the EGFR wild-type group (EGFR-WT). The primary objective was progression-free survival (PFS) at 3 and 9 months for EGFR-WT and EGFR+ patients. RESULTS: Overall, 204 patients (gefitinib 104 and G+F 100) and 175 patients (erlotinib 87 and E+F 88) were enrolled in the EGFR+ and EGFR-WT cohorts. In the EGFR+ cohort, the primary endpoint was reached, with 58% of the G+F group patients being nonprogressive at 9 months. Adding fulvestrant to gefitinib was not associated with improved PFS (9.9 vs 9.4 months) or overall survival (OS; 22.1 vs 28.6 months). In the EGFR-WT cohort, the primary endpoint was also achieved (33.7% of the patients were nonprogressive at 3 months). Adding fulvestrant to erlotinib was not associated with improved outcome (PFS 1.8 vs 2.0 and OS 10.3 vs 7.3 months). No PFS difference was observed regarding estrogen receptor alpha expression. The tolerance was as expected with no treatment-related death. CONCLUSIONS: Adding fulvestrant to EGFR-TKI is feasible, but not associated with prolonged PFS regardless of EGFR status. The lack of benefits while combining fulvestrant to EGFR-TKI does not support its future development in an unselected population.
