Introduction: Lung cancer is one of the most frequent cancers nowadays worldwide. Different histological types can be observed, the most frequent being adenocarcinoma, non-small cell carcinoma and, thirdly, small cell and squamous cell carcinoma.
Objective: to calculate the frequency of histological types of lung cancer in biopsies of patients older than 18 years analyzed in an anatomic pathology laboratory in Rosario in the period 2016-2021.
Materials and Methods: a quantitative, descriptive, observational, cross-sectional, retrospective, descriptive study was carried out from the analysis of biopsy reports of lung nodular lesions.
Results: 197 biopsies of pulmonary nodular lesions were analyzed. 132 reports indicated the presence of neoplastic cells. The highest frequency was in the range of 60-69 years. The 60.9% of the patients were male. The most frequent histologic type was adenocarcinoma NOS (30%), followed by non-small cell undifferentiated carcinoma (16%) and small cell (10%) and squamous cell (10%) carcinoma. Biopsy specimens were representative in 86% of cases.
Conclusions: the most frequent histologic type in the present series was adenocarcinoma NOS, with a higher frequency between 60-69 years in the male sex, as reported in the international literature
