EVIDENS is an ongoing, prospective, non-interventional study evaluating the effectiveness and safety of nivolumab in lung cancer patients in France (ClinicalTrials.gov NCT03382496).
Adults with a ...pathologically confirmed diagnosis of lung cancer and initiating treatment with nivolumab were recruited from 146 sites in France. This analysis included only patients with non-small cell lung cancer (NSCLC) who received ≥1 nivolumab infusion, and evaluated patient characteristics at the time of nivolumab initiation and its effectiveness and safety after a median follow-up of 18 months.
A total of 1,420 patients with NSCLC were included, most of whom had an Eastern Cooperative Oncology Group performance status (ECOG PS) of 0-1 (82.9%), non-squamous histology (69.2%) and stage IV disease (91.4%). Brain metastases were present in 19.9% of patients. Nivolumab was a second-line or ≥third-line regimen in 73.6% and 26.1% of patients, respectively. Almost all patients had prior chemotherapy (99.7%). Median overall survival was 11.2 months (95% confidence interval CI: 10.0-12.4). ECOG PS, smoking status, corticosteroids at baseline, epidermal growth factor receptor mutation status, presence of symptomatic brain metastases and treatment-related adverse events (TRAEs) were independent predictors of survival. Grade 3 and 4 TRAEs were reported in 105 (7.4%) and 12 (0.8%) patients, respectively; no treatment-related deaths were reported.
Preliminary results of the EVIDENS study confirm the effectiveness and safety of nivolumab, mostly in pre-treated advanced NSCLC patients, with similar benefits to those observed in the phase III randomized clinical trials, despite a broader study population.

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,
with "at least one biomarker status known" and "at least
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 EUR13 230 per life-year saved, which decreased to EUR7444 per life-year saved with the "at least
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.

Patients who suffer from non-small-cell lung cancer (NSCLC) with ipsilateral mediastinal lymph node involvement (N2) belong to a heterogeneous subgroup of patients. We analyzed the prognosis of ...patients with resected N2 NSCLC to propose homogeneous patient subgroups.
The present study comprised 702 consecutive patients from six French centers who underwent surgical resection of N2 NSCLC. Initially, two groups of patients were defined: patients with clinical N2 (cN2) and those with minimal N2 (mN2) disease were patients in whom N2 disease was and was not detected preoperatively at computed tomographic scan, respectively.
The median duration of follow-up was 52 months (range, 18 to 120 months). A multivariate analysis using Cox regression identified four negative prognostic factors, namely, cN2 status (P <. 0001), involvement of multiple lymph node levels (L2+; P <.0001), pT3 to T4 stage (P <.0001), and no preoperative chemotherapy (P <. 01). For patients treated with primary surgery, 5-year survival rates were as follows: mN2, one level involved (mN2L1, n = 244): 34%; mN2, multiple level involvement (mN2L2+, n = 78): 11%; cN2L1 (n = 118): 8%; and cN2L2+ (n = 122): 3%. When only patients with mN2L1 disease were considered, the site of lymph node involvement according to the American Thoracic Society numbering system had no prognostic significance (P =.14). Preoperative chemotherapy was associated with a better prognosis for those with cN2 (P <.0001). Five-year survival rates were 18% and 5% for cN2 patients treated with and without preoperative chemotherapy, respectively.
This study has identified homogeneous N2 NSCLC prognostic subgroups and suggests different therapeutic approaches according to the subgroup profile.
The interest of first- and second-line treatments in non-small cell lung cancer (NSCLC) has been demonstrated by successive randomized trials. Improvements in lung cancer care have routinely allowed ...a significant proportion of patients to be considered for third-line treatment.
A retrospective analysis was performed, including all consecutive patients with advanced NSCLC, who received at least three lines of systemic antineoplastic treatment at our institution.
From a population of 613 patients treated with first-line treatment, a total of 173 patients received third-line treatment (cytotoxic chemotherapy in 131 patients; epidermal growth factor (EGFR) tyrosine kinase inhibitors in 42 patients). Only 13 patients (8%) received less than 75% of the theoretical dose intensity; 22 patients (13%) presented with severe toxicities. Symptom relief and performance status (PS) improvement were observed in 121 (92% of the 131 patients with symptoms) and 90 patients (52%), respectively. Using multivariate analysis, survival after third-line treatment was significantly increased in patients younger than 70 years-old (hazard ratio HR = 0.73, 95% confidence interval CI: 0.53–0.99, p = 0.047), who smoked less than 10 pack-years (HR = 0.82, 95% CI: 0.57–0.93, p = 0.036), with no cancer-related symptoms (HR = 0.75, 95% CI: 0.61–0.92, p = 0.007), a weight loss inferior to 5 kg since the beginning of second-line (HR = 0.63, 95% CI: 0.52–0.75, p = 0.013), a PS 0 to 1 (HR = 0.81, 95% CI: 0.76–0.86, p = 0.008), and no extrathoracic tumor spread at initiation of third-line treatment (HR = 0.67, 95% CI: 0.47–0.94, p = 0.042). Disease control after both first- and second-line treatments was the strongest predictor of prolonged survival after third-line treatment (HR = 0.47, 95% CI: 0.33–0.67, p = 0.001).
Patients with advanced NSCLC may benefit from third-line treatment. The best candidates can be identified using standard prognostic factors, such as PS, and disease control after first- and second-line treatments.

Territorial differences in the access to innovative anticancer drugs have been reported from many countries. The objectives of this study were to evaluate access to innovative treatments for ...metastatic lung cancer in France, and to assess whether socioeconomic indicators were predictors of access at the level of the municipality of residence.
All incident cases of metastatic lung cancer hospitalised for a chemotherapy in public hospitals in 2011 were identified from the French National Hospital discharge database. Information on prescription of innovative drugs from an associated database (FICHCOMP) was crossed with the population density of the municipality and a social deprivation index based on national census data.
Overall, 21,974 incident cases of metastatic lung cancer were identified, all of whom were followed for 2 years. Of the 11,486 analysable patients receiving chemotherapy in the public sector, 6959 were treated with a FICHCOMP drug at least once, principally pemetrexed. In multivariate analysis, prescription of FICHCOMP drugs was less frequent in patients ≥66 years compared to those ≤55 years (odds ratio: 0.49 0.44-0.55), in men compared to women (0.86 0.79-0.94) and in patients with renal insufficiency (0.55 0.41-0.73) and other comorbidities. Prescription rates were also associated with social deprivation, being lowest in the most deprived municipalities compared to the most privileged municipalities (odds ratio: 0.82 0.72-0.92). No association was observed between the population density of the municipality and access to innovative drugs.
Although access to innovative medication in France seems to be relatively equitable, social deprivation is associated with poorer access. The reasons for this need to be investigated and addressed.

To evaluate prognostic and predictive molecular biomarkers in early-stage non-small cell lung carcinoma (NSCLC) receiving neoadjuvant chemotherapy.
The IFCT-0002 trial compared two neoadjuvant ...regimens in 528 stages I to II NSCLC patients. DNA extraction of snap-frozen surgical samples taken from 208 patients receiving gemcitabine-cisplatin or paclitaxel-carboplatin regimens allowed for the identification of 3p allelic imbalance, Ras association domain family 1A (RASSF1A) and death-associated protein kinase 1 (DAPK1) promoter methylation, and epidermal growth factor receptor, K-ras, and TP53 mutations. Multivariate analysis identified prognostic and predictive effects of molecular alterations. A Bootstrapping approach was used to assess stability of the prognostic models generating optimism corrected indexes.
RASSF1A methylation correlated significantly with shorter disease-free survival (DFS; adjusted HR = 1.88, 95% CI: 1.25-2.82, P = 0.0048) and shorter median overall survival (OS; adjusted HR = 2.01, 95% CI: 1.26-3.20, P = 0.020). A computed bootstrap resampling strategy led to a prognostic model, including RASSF1A, DAPK1, and tumor stage, dividing patients into three prognostic groups, with median OS ranging from 34 months for high-risk patients (HR for death = 3.85, 95% CI: 1.79-6.40) to more than 84 months for moderate (HR = 1.85, 95% CI: 0.97-3.52) and low-risk patients (reference group; P = 0.00044). In addition, RASSF1A methylation predicted longer DFS in patients treated with paclitaxel-carboplatin compared with gemcitabine-cisplatin (adjusted HR = 0.47, 95% CI: 0.23-0.97, P(interaction) = 0.042).
Following neoadjuvant chemotherapy, RASSF1A methylation negatively impacted prognosis of early-stage NSCLC. Along with DAPK1 methylation and tumor stage, RASSF1A methylation allowed definition of three subgroups with strikingly different prognosis. Conversely, significantly longer DFS following paclitaxel-based neoadjuvant chemotherapy for patients whose tumors showed RASSF1A methylation suggested its predictive interest in stages I and II NSCLC.
gene methylation predicts longer disease-free survival (DFS) and overall survival (OS) in patients with early-stage non-small-cell lung cancer treated using paclitaxel-based neo-adjuvant chemotherapy ...compared to patients receiving a gemcitabine-based regimen, according to the randomized Phase 3 IFCT (Intergroupe Francophone de Cancérologie Thoracique)-0002 trial. To better understand these results, this study used four human bronchial epithelial cell (HBEC) models (HBEC-3, HBEC-3-RasV12, A549, and H1299) and modulated the expression of RASSF1A or YAP-1. Wound-healing, invasion, proliferation and apoptosis assays were then carried out and the expression of YAP-1 transcriptional targets was quantified using a quantitative polymerase chain reaction. This study reports herein that gemcitabine synergizes with RASSF1A, silencing to increase the IAP-2 expression, which in turn not only interferes with cell proliferation but also promotes cell migration. This contributes to the aggressive behavior of RASSF1A-depleted cells, as confirmed by a combined knockdown of IAP-2 and RASSF1A. Conversely, paclitaxel does not increase the IAP-2 expression but limits the invasiveness of RASSF1A-depleted cells, presumably by rescuing microtubule stabilization. Overall, these data provide a functional insight that supports the prognostic value of
gene methylation on survival of early-stage lung cancer patients receiving perioperative paclitaxel-based treatment compared to gemcitabine-based treatment, identifying IAP-2 as a novel biomarker indicative of YAP-1-mediated modulation of chemo-sensitivity in lung cancer.

KRAS mutations are detected in 20% to 30% of NSCLC. However, KRAS mutation subtypes may differently influence the outcome of patients with advanced NSCLC.
In the Biomarkers France study, 4894 KRAS ...mutations (26.2%) were detected in 4634 patients from the 17,664 enrolled patients with NSCLC. Survival and treatment data on noncurative stage III to IV NSCLC were available for 901 patients. First- and second-line treatment effects on progression-free survival and overall survival were analyzed according to the KRAS mutations subtype.
Over 95% of patients with KRAS mutation were smokers or former smokers who were white (99.5%), presenting with adenocarcinoma (82.5%). The most common KRAS mutation subtype was G12C (374 patients; 41.5%), followed by G12V (168; 18.6%), G12D (131; 14.5%), G12A (62; 6.9%), G13C (45; 5.0%), G13D (31; 3.4%), and others (10; 1%). Approximately 21% of patients had transition mutation and 68.2% had a transversion mutation. G12D and transition mutations were predominant in never-smokers. The median overall survival for patients with KRAS-mutated NSCLC was 8.1 months (95% confidence interval CI: 7.5–9.5), without any differences according to the different KRAS subtypes mutations. The median progression-free survival was 4.6 months (95% CI: 4.2–5.1) for first-line treatment and 4.8 months (95% CI: 4.3–6.8) for second-line treatment, without any differences according to the different KRAS subtypes mutations.
KRAS mutation subtypes influenced neither treatment responses nor outcomes. The KRAS G12C mutation was detected in 41.5% of patients, who are now eligible for potent and specific G12C inhibitors.
