The importance of prognostic factors in the analysis of lung cancer clinical trials has long been recognized. In this paper, many prognostic factors were considered and their comparison between male and female group results were evaluated. The presence of symptoms at the time of diagnosis of lung cancer was not found to be different between women and men in this study. The women had a lower smoking incidence (45.7%) than men (90.6%). Squamous cell carcinoma represented the most common lung malignancy among men (40.6%), whereas adenocarcinoma represented the most frequently diagnosed lung cancer among women (57.1%). On the average, 45% of the patients had advanced disease at the moment of diagnosis. Compared with women, men had a higher prevalence of cachexia (40%).
