title: [The relationship between human papillomavirus (HPV) infection and penile cancer].
abstract: Human papillomavirus (HPV) may be carcinogenic effectors in a variety of human lower genital tract malignancies. We evaluated HPV status with respect to clinical and pathological features and prognosis of penile carcinoma. We searched for HPV infected cells (Koilocytosis) within the primary lesion of cancer tissue from 78 patients with penile squamous cell carcinoma. The following variables were recorded : age, tumor size, clinical stage, lymphatic and venous invasion, histologic and nuclear grade, Broders grade, infiltration status, and lymph node and distant metastasis. Koilocytosis were detected 55.1% (43 of 78) of patients. Tumors with Koilocytosis had better differentiation (p=0.0443) and lower grade (better keratinized) in Broders grading system (p=0.0116) than HPV negative tumors. No difference was found in the 5-year survival rate (p=0.5693). Our data suggest that the presence of Koilocytosis does not influence prognosis in penile cancer.
