Histological subtypes of lung cancer in male and female patients. In the proportion of histological subtypes, an even distribution was found between men and women. Adenocarcinoma was the most common histological subtype (50 % vs. 58.2 %, p = 0.204) followed by squamous cell carcinoma (21.1 % vs. 20.9 %, p = 1.000). Small-cell lung cancer counted for 16.4 % and 15.7 %, while adenosquamous carcinoma for 3.9 % and 1.5 % of all cases in male and female patients (p = 0.987 and p = 0.370, respectively). Large-cell lung carcinoma was found in men only (p = 0.056). The proportion of carcinoids was 2.6 % and 3 % (p = 1.000) in men and women.
