      Background
      RYTHMIC (Réseau tumeurs THYMiques et Cancer) is a nationwide network for thymic malignancies, which was appointed in 2012 by the French National Cancer Institute, as part of its rare cancer program. The objectives of the network include a territorial coverage by regional expert centers, the dissemination of highest standards for the diagnostic and therapeutic management of patients, and the promotion of collaborative research. Registration in RYTHMIC of all patients diagnosed with thymic malignancy is recommended as part of good clinical practice for oncologists.

      Methods
      Starting January 2012, the management of all patients diagnosed with thymic malignancy in France has been discussed on a real-time basis at a reference national multidisciplinary tumor board (MTB), which is organized twice a month using a web-based conferencing system. Decision-making is based on consensual recommendations, that were originally established using available evidence, and are updated and approved each year by all members of the network. A prospective database of all patients is hosted by the French Thoracic Cancer Intergroup. We report the characteristics and treatment modalities of patients included during the first year.

      Results
      From January to December 2012, 257 patients were enrolled in RYTHMIC. There were 126 (49%) men and 131 (51%) women; mean age at diagnosis was 54.5 years. Among 214 cases, histology was thymoma for 146 (56%) patients (11 (5%) type A, 28 (13%) type AB, 22 (10%) type B1, 35 (16%) type B2, 24 (11%) type B3, 26 (12%) mixed type), and thymic carcinoma for 33 (15%) patients, 8 of which were neuroendocrine carcinomas; other histologies were diagnosed for 35 (16%) patients. Among 144 cases, Masaoka-Koga stage was I, IIA, IIB, III, IVA, and IVB in 34 (24%), 19 (13%), 20 (14%), 22 (15%), 35 (24%), and 14 (10%) patients, respectively. 44 (17%) patients presented with autoimmune disorder, consisting of myasthenia gravis in 28 cases. Surgery was performed for 166 patients, mostly using a median sternotomy approach (52% of cases). Postoperative radiotherapy was delivered to 42 patients; 71 patients received perioperative chemotherapy. Exclusive chemotherapy/radiotherapy was administered to 20 and 4 patients, respectively. Mature data will be presented at the meeting.

      Conclusion
      This first analysis of the RYTHMIC prospective cohort demonstrates the feasibility of a national MTB for thymic malignancies, that, besides ensuring all patients an equal access to highly specialized treatment, provides with a comprehensive tool to monitor dedicated actions to improve the management of patients in the future, increase the quality-of-care, and screen patients for future translational research and clinical trials.

      MO06.06 - Oral vinorelbine (NVBo) and cisplatin (P) or pemetrexed (Pem) and P as first-line chemotherapy for non squamous (NS) metastatic or locally advanced non small cell lung cancer (M or LA NSCLC): Final results of a prospective randomised phase II trial (NAVoTrial 1) (ID 276)

      • Abstract
      • Presentation
      • Slides

      Background
      NVBo and P are an established regimen in advanced NSCLC. The approval of Pem and P in NS NSCLC recognises histology as treatment driver even if the higher chemosensitivity of NS NSCLC is recognised and reported with other chemotherapies (Ardizzoni. JNCI 2007). NVBo + P also showed better survival in NS NSCLC than in Squamous NSCLC (Tan. Ann.Oncol. 2009). The current randomised (2:1) phase II trial assessed disease control (DCR) (SD + PR + CR) of NVBo/CDDP or PEM/CDDP in NS NSCLC.

      Methods
      Stage IIIB/IV untreated/relapsed NS NSCLC pts were randomised to receive q3w NVBo 80 mg/m² D1D8 (60 at Cycle 1) + P 80 mg/m² D1 (Arm A) or Pem 500 mg/m² + P 75 mg/m² D1 (Arm B). After 4 cycles of combination, non PD pts received single agent NVBo (Arm A) or PEM (Arm B) as maintenance until progression or toxicity. Pts were randomised on a 2/1 basis and stratified according to Stage (IIIB - IV - relapse), non SCC confirmed by histology or cytology, gender, smoking status and centre.

      Results
      From 11/09 to 02/11, 153 patients were enrolled in 31 centers and randomised to Arm A (102 pts) or Arm B (51 pts). DCR after combination and maintenance was 75.0% (95% CI, 65.3 to 83.1) in Arm A and 76.5% (95% CI, 62.5 to 87.2) in Arm B. Median PFS was 4.2 (95% CI, 3.6 to 4.7) and 4.3 months (95% CI, 3.8 to 5.6) in Arm A and Arm B, respectively. Median OS was 10.2 months (95% CI, 7.8 to 11.9) and 10.8 months (95% CI, 7.0 to16.4) in Arm A and Arm B, respectively. During the combination period Grade 3/4 neutropenia was 44.0% in Arm A and 18.3% in Arm B but febrile neutropenia was 2% in both arms; grade 3/4 thrombopenia was 0% and 6% in Arm A and Arm B, respectively.

      Conclusion
      Both doublets reported good efficacy and acceptable tolerability. The maintenance allowed continuation of effective treatment with either oral vinorelbine or pemetrexed as single agent, with an acceptable safety with both agents. These results are sufficiently compelling to consider whether a phase III randomised non inferiority study with oral vinorelbine maintenance after induction vinorelbine/cddp could be as effective as pemetrexed maintenance. An oral maintenance may be a definite advantage over intravenous maintenance.

      O15.03 - Phase III, randomized, multicenter study comparing in elderly patients (≥70 years) with stage IV non small-cell lung cancer (NSCLC) a standard strategy of treatment allocation (carboplatin based bi-therapy or monotherapy with docetaxel) based on performance status (PS) and age with an experimental strategy allocating the same chemotherapies or best supportive care (BSC) according to a comprehensive geriatric assessment (CGA) - Study ESOGIA-GFPC-GECP 08-02.

      Background
      Incidence of advanced NSCLC in the elderly is increasing. The use of a CGA is recommended to detect the patient’s vulnerability but its integration in treatment decision making has never been prospectively evaluated. The main objective of this study was to show that, compared to a standard strategy based on PS and age, the use of a CGA can improve the management of NSCLC in first line.

      Methods
      Randomized, multicentric, prospective phase III study in patients ≥70 y, PS 0-2 with stage IV NSCLC. We compared in arm A a standard algorithm of chemotherapy allocation based on PS and age: carboplatin based doublet in PS≤1 and age ≤75y, mono-therapy in PS =2 or age >75y with in arm B an experimental strategy of treatment allocation based on CGA: carboplatin based doublet for fit patients, mono-therapy for vulnerable patients and BSC for frail patients. Carboplatin (AUC5,d1), was associated to pemetrexed (500 mg/m2,d1) in non-squamous tumors and to gemcitabine (1000 mg/m2, d1-8) in squamous tumors, monotherapy was docetaxel 38 mg/m2 (d1-8). Four cycles of chemotherapy were to be given every three weeks. The main endpoint was time to failure treatment (TTF=duration between the date of randomization and the date the patient was withdrawn from treatment for any reason (progression, toxicity, death), secondary endpoints were Overall Response Rate (ORR), overall survival (OS), toxicity and quality of life (QoL), survival adjusted on QoL .

      Results
      493 patients were randomized from 01/2010 to 01/2013 by 45 centers. Patients characteristics were: male: 74%, median age: 77 (70-91) years, non-squamous histology: 71.8%, PS 0-1: 81.4%, ADL<6:13.9%, IADL<4:27.5%, Charlson’s index ≥2: 23%, score GDS 5≥3:2.5%. The 2 arms were well-balanced for patients characteristics except for ADL<6 (17.4% in arm A vs 10.3% in arm B). Respectively in arms A and B, 34.4% and 47% patients received a carboplatin based doublet, 65.6% and 31.5% received docetaxel and in arm B 21.5% received BSC. There was no significant difference in terms of TTF, respectively for arm A and arm B: median TTF was 99 days (d), 95%CI:[89; 126] vs. 98 d, 95%CI:[81;135], p=0.7149 and in terms of mOS: 196 d in arm A, 95%CI [171;231] vs. 185 d in arm B ,95%CI [148;235], p=0.7784. All grades toxicities were significantly less frequent in arm B than in arm A (93% vs.86.2%, p=0.016), but there was no difference in terms of grade 3-4 toxicities. All the secondary endpoints data will be updated at time of the meeting.

      Conclusion
      this large phase III study failed to show a superiority of a CGA based strategy of treatment allocation in terms of TTF. In experimental arm, 21.5% of frail patients according to Balducci’s criteria were enrolled and received an exclusive BSC management. Carboplatin-based doublets with pemetrexed and gemcitabine according to histology are feasible with a good profile of tolerance in selected elderly patients. This study will help to precise the most relevant geriatric tools and their cut-off in order to improve the management of the elderly with advanced NSCLC.

      O18.03 - The BioCAST / IFCT-1002 study: a comprehensive overview of demographic, risk exposure and somatic mutations of non-small cell lung cancer occurring among French never smokers (ID 3293)

      10:30 - 12:00  |  Author(s): E. Dansin

      • Abstract
      • Presentation
      • Slides

      Background
      Lung cancer occurring in never-smoker (LCINS) is a particular entity. Although the definition is strict (less than 100 cigarette in lifetime) never-smokers are frequently misclassified and no study gives a comprehensive analysis of this group, particularly in a European setting.

      Methods
      All consecutive never-smoker patients diagnosed with a non-small cell lung cancer in one of the 75 participating centers throughout France, between November 2011 and January 2013, were included in this prospective survey. All patients underwent a detailed questionnaire supported by a trained staff during a phone interview. Somatic mutations and cancer clinical and histological data were also recorded from medical charts.

      Results
      Overall, 384 never-smokers were included and 336 interviews were completed. Most of them were women (n=319, 83.1%). The mean age at diagnosis was 69.8 ± 12.02 and 10.9% were under 55 years-old. None reported alternative smoking (pipe, cigar, water-pipe, gum, or cannabis). Most of them originated from Western and Southern Europe (90.5%). Overall, 219 (65.6%) reported a passive smoking exposure in a domestic setting (n=198; 59.3%), and/or at workplace (n=60; 18.0%). Patients had a personal history of pneumonia in 6.2%, tuberculosis in 8.3%, COPD in 13.0%, and a cancer at another site in 16.6%. Eighty patients reported at least two relatives with lung cancer (24.0%). Definite occupational exposure was observed in 12.0% (n=44) for diesel, 7,1% (n=26) for asbestos, 3.3% (n=12) for poly-aromatic hydrocarbons, 2.4% (n=9) for silica, 0.8% (n=3) for chrome, and 0.5% (n=2) for painting. Exposure to cooking oil was noted in 123 patients (36.8%) with a mean of 49.4 ± 356.7 cooking-dish year. Moreover, 79.7% (n=259) patients were ever exposed to solid fuel fumes for cooking or heating (21.2% during more than 50% of their lifetime). Among women, 91.7% already reached menopause (mean age 49.3 ± 5.6 years-old), 115 (41.7%) were ever-exposed to oral contraceptive (mostly oestrogen-containing drugs), and 25.5% to post-menopause hormone replacement therapy (oral or transdermal). Most of lung cancers were adenocarcinoma (n=327, 85.2%) followed by squamous cell carcinoma (n=29, 7.6%) and large cell carcinoma (n=17; 4.4%). Among adenocarcinoma, 71% were invasive, 4% in-situ, 2% minimally-invasive, 2% variant of invasive, and 20.0% were NOS. Cancer stage was I in 9.2%, II in 5.8%, III in 11.8% and IV in 73.2%. At least one biomarker was tested in 359 patients (93.5%). We found 148 patients with EGFR mutations (43.5% out of the EGFR-tested patients), 20 with KRAS mutations (6.8%), 24 with ALK translocation (12.5%), 10 with BRAF mutation (4.5%), 8 with HER2 mutation (4.0%) and 4 with PIK3CA (2.1%). Overall, 27.0% samples remain wild type, 2.1% with multiple mutations, 71.0% with a single mutation, and 20.6% with missing data.

      Conclusion
      We provide here the largest cohort of LCINS in a European setting with reliable data on tobacco intoxication, occupational exposure, and hormonal treatments, since collected by a trained staff through phone interview. In this perfectly clinically characterized cohort, molecular analyses showed that 72% of tumors exhibited oncogenic targetable mutations.
