Abstract only e19078 Background: In recent years, many major advances have been made in non-small-cell lung cancer (NSCLC), and in particular in adenocarcinoma, but not in SCLC. In 2010, the French College of General Hospital Respiratory Physicians (CPHG) performed a prospective multicentre epidemiological study (KBP-2010-CPHG) to describe the baseline characteristics and management of all new cases of primary lung cancer and to evaluate survival. The present abstract reports results in SCLC patients. Methods: 7,051 patients ≥18 years presenting with a new case of primary lung cancer, histologically or cytologically diagnosed between 1 January and 31 December 2010 and managed in the respiratory department of one of the 104 general hospitals participating in the study, were included. A standardised form was completed for each patient. A steering committee checked data collection exhaustiveness. SCLC data were analysed separately. Results: There were 968 SCLC patients: mean age, 65.6 years (+/-10.6); 23.2% female; 4.4% non-smokers (11 % in women), 35.8% ex-smokers, 59.8% current smokers; 63.4% with performance status 0 or 1; 59.9% having lost weight within the previous 3 months (19.8% of whom had lost >10 kg). Main tumour characteristics at diagnosis were: 71.2% stage IV, 24.7% stage IIIA or IIIB, 4.1% of stage <III. 15.2% of patients received chemo-radiotherapy and 73.4% chemotherapy (86.2% platinum-based). Carboplatin was more commonly used in patients >70 (59.1%) than <70 years of age (40.9 %). One-year mortality was 64.2%. Compared with NSCLC patients, patients with SCLC more frequently were active smokers (59.8% vs.47.6%), lost weight (59.9% vs. 52.4%), and presented with stage IV tumour at diagnosis (71.2% vs. 58.3%); first line therapy was more frequently platinum-based chemotherapy (86.2% vs. 61.2%) and less frequently curative surgery (1.6% vs. 19%), and mortality was higher (64.2% vs. 55.2%). Conclusions: In 2010, prognosis remains poor in SCLC. Compared with NSCLC, it was more frequently associated with active smoking and stage IV disease, and showed a lower rate of surgery.
