Lip Cancer: a 16-Year Retrospective Epidemiological Study in Eastern Part of Turkey

Abstract

Objective: To review lip cancer patients with respect to age, gender, location and histological type of tumour, and risk factors. Methods: This retrospective study was conducted at the Yuzuncu Yil University, Van, Turkey, and comprised-medical records of the histologically confirmed lip cancer patients who presented between 1994 and 2010. No patient had neck nodes or evidence of distant metastasis. Results: Of the 91 patients 73(80.22%) were men and 18(19.78%) were women. The overall mean age was 62.32 +/- 13.88 years (range: 25 to 97 years). Histologically, the tumour was a squamous cell carcinoma in 81(89.01%) cases and a basal cell carcinomas in 10(10.99%) cases. Upon admission, the mean diameter of the tumour in squamous cell carcinoma patients was 2.03 +/- 1.23 cm and 1.87 +/- 1.29 cm in basal cell carcinoma patients. As for the tumour differentiation, 67(84.72%) of the squamous cell carcinoma cases were well differentiated, while 14(17.28%) were moderately differentiated. Conclusion: The incidence of lip cancer was found to be higher among men, while the histopathological type was mostly squamous cell carcinoma and well differentiated.
