Prognostic factors in patients with penile cancer after surgical management.
Purpose: To examine the possible prognostic factors in patients with penile cancer after surgical management and to identify the independent predictive factors of the prognosis.
Materials and methods: Clinical data of 135 patients with penile cancer who underwent surgical management in two medical centers were collected. Follow-up data were available for 103 patients. Possible prognostic factors including patient's age; smoking or not; course of disease; phimosis or not; type of surgery; tumor stage; nodal stage; tumor grade and pathological lymph nodes metastasis were retrospectively analyzed by univariate and multivariate analyses with Cox regression.
Results: Five-year cancer-specific survival (CSS) and 1-year CSS were 88.5 and 98.1%, respectively. Univariate Cox analysis revealed that nodal stage and pathological lymph nodes metastasis were significant prognostic factors. Multivariate Cox analysis revealed pathological lymph nodes metastasis was the independent predictive factor of the prognosis.
Conclusion: Pathological lymph nodes metastasis is the independent predictive factor worsening the prognosis in patients with penile cancer.
