Human papillomavirus (HPV) infection is one of the risk factors contributing to the pathogenesis of lung cancer. The aim of the study was to determine the presence of HPV in non-small cell carcinomas of the lung. The study included 40 tumors: 22 squamous cell carcinomas, 13 adenocarcinomas and 5 large cell carcinomas. HPV was found in 4 cases (10%). High risk HPV was present in 3 tumors: in one squamous cell carcinoma, one large cell carcinoma and one adenocarcinoma, while low risk HPV was detected in one adenocarcinoma.
