Lung cancer is a major public health problem due to its continued increase. In 2010, the French College of General Hospital Respiratory Physicians (CPHG) performed a prospective multicenter epidemiological study (KBP-2010-CPHG) to describe the baseline characteristics and management of all new cases of primary lung cancer; to evaluate 1, 4 and 5-year patient survival rates; and to compare results with those from a similar study performed 10 years ago (KBP-2000-CPHG). Data were collected on a standardized form for all patients ≥18 years with primary lung cancer, histologically or cytologically diagnosed between January 1 and December 31, 2010 and managed in a general hospital. 7,610 patients were enrolled in 119 centers. 6,083 patients (86.3%) had non-small-cell lung cancer (NSCLC); among them, 24.4% were female (vs. 16% in 2000; p < .0001). There was no difference between male and female NSCLC patients regarding age (65.7± 10.9 vs. 64.9± 13.0, p = 0.03). Regarding smoking status, between 2000 and 2010, women remained more frequently non-smoker compared to men (34.2% vs. 4.7%), less frequently former smoker (21.3% vs. 46.8%) and showed lower consumption (37.2 vs. 43.7 PY) (p < .0001). However, in 2010, the percentage of non-smokers nearly doubled in men (2.5% vs. 4.7%; p < .0001) whereas it remained stable in female (p < .32). Regarding tumor characteristics, between 2000 and 2010, the percentage of adenocarcinomas significantly increased in both women (53.4% in 2000 vs. 65.9% in 2010; p < .0001) and men (32.4% vs. 49.4%; p < .0001). However, in 2010, tumors remained more frequently adenocarcinomas in women than in men (65.9% vs.49.4%; p < .0001). In addition, in 2010, when explored (48.5% in women vs. 31.0% in men; p < .001), an EGFR mutation was more frequently found in women than men (20.6% vs. 5.2%; p < .0001), stage IV tumor was more frequent in women than men (62.4% vs. 56.9%; p = 0.0008), and regarding first-line treatment, 64.5% of women vs. 61.0% of men (p = .01) received chemotherapy and 13.4% of women vs. 5.7% of men (p < .0001) targeted therapy. In 10 years, percentages of women, non-smokers among men, and adenocarcinomas in both men and women increased. However, differences between women and men in baseline and tumor characteristics persist.
