Factors of prognosis in cancer of the penis

Abstract

Carcinoma of the penis is a rare tumor. With adequate treatment of patients having no late metastases, 5-year survival is as high as 91.6%; 1-year relapse-free survival is 45.9%. Multivariance analysis shows that regional lymph nodal involvement is the only significant poor predictor in penile carcinoma, which reduces 5-year survival rates from 94.4 to 73.9%. Univariance analysis indicates that the partial effect of therapy, the endophytic form of primary tumor growth, a recurrence occurring after achievement of a complete therapeutic effect exert a significant negative action on survival. An insignificant survival reduction is observed in groups of patients less than 30 and more than 60 years with a neoplasm > 4 cm of high T stage being located on the glans et corpus penis.
