Outcomes of multidisciplinary treatment in penile cancer: Experience from Thailand.

Abstract

555 Background: Penile cancer is relatively more common in Thailand compared to western countries. We report multidisciplinary treatment outcomes of penile squamous cell carcinoma at a regional center in northeast of Thailand. Methods: Using an institutional database, a total of 68 patients with squamous cell carcinoma of penis treated during 2009-2015 were identified. Patient demographics, pathological data, and treatment modality were reviewed. Survival data was calculated using the Kaplan-Meier method. Results: Median age was 53 years (25-89 years) and the median follow-time was 2.7 years. At presentation, 39 patients (57.4%) were node positive, and 9 (13.2%) had metastatic disease. Management was penile preserving surgery in 13 patients, partial penectomy in 36 patients, total penectomy in 15 patients, and palliative with radiation and/or chemotherapy in 4 patients. The 3-year overall survival for patients with N0-1 and N2-3 was 86% and 35% respectively. For those with high risk (N2/N3) non-metastatic disease, multimodality treatment improved overall survival significantly compared with surgery alone (13.7 mo vs 8.6 mo; HR 0.32, p-value = 0.04) Conclusions: Patients present with locally advanced disease had a poor prognosis. Multidisciplinary management improved overall survival N2/N3 patients.
