Background: There are reports showing a better survival rate among females with non-small lung cancer (NSCLC). Preliminary studies conducted at São Lucas da PUCRS Hospital (HSL-PUCRS), has shown similar results. The purpouse of this study was to clarify the role of gender in relation to survival in patients with NSCLC. Methods: In a retrospective cohort study, we examined the survival of 478 NSCLC patients who underwent surgical curative treatment, as staging, at HSLPUCRS between 1990 and 2009. Survival rates were analysed by Kaplan-Meier plots. Cox proportional hazards analysis was performed to identify potential confounding factors. Results: The 5-year survival was 55,6% for women and 38,8% for men in analysis of uncensored patients lost to follow (P=0,005). Considering only patients in stage I survival rates was 75,2% and 47,9%, for women and men, respectively (P=0,007). After adjustment for several factors (age, hemoglobin, histology, tumor size, surgical procedure and postoperative complications), female gender protective effect persisted only in stage I. The hazard ratio in men in stage I was 1,95 (IC95%: 1,16 a 3. 27, P=0,012), when compared to women. Conclusion: The results of this study have shown that female gender is a protective factor for mortality in patients with NSCLC submitted to surgery with curative intent in stage I when compared to males. This effect is not observed in patients in stage ≥II.
