PurposeWe evaluated the influence of koilocytosis, and other clinical and pathological variables in the risk of groin metastasis and death in penile cancer patients.Materials and MethodsFrom January 1994 to January 2004, 172 patients with squamous cell carcinoma of the penis were treated at a single cancer center. Of these patients 144 were retrospectively studied to analyze prognostic factors and establish the role of koilocytosis in penile cancer. Univariate and multivariate analyses were performed, and Kaplan-Meier survival curves were generated.ResultsA total of 102 patients (71%) underwent groin dissection, of whom 84 (58.3%) had inguinal metastasis. Koilocytosis was present in 91 patients (63.1%) and it was associated with low and moderate primary tumor grade on univariate analysis (p = 0.0005). Although koilocytosis statistically correlated with Jackson stage (p = 0.017) and tumor grade (p = 0.002), it had no impact on disease specific survival (p = 0.912). Metastatic inguinal disease correlated with patient age, Jackson and disease specific survival. Only Jackson stage and inguinal relapse after groin dissection influenced overall survival on multivariate analysis (each p = 0.001).ConclusionsAccording to all studied variables only patient age and Jackson stage correlated with an increased risk of groin disease. Koilocytosis was rarely found in high grade penile tumors and it did not correlate with a high risk of metastatic groin disease or death.
