Role of paclitaxel and platinum-based adjuvant chemotherapy in high-risk penile cancer

AIM: To study the efficacy and safety of paclitaxel and platinum doublet chemotherapy in penile cancer patients with high-risk features of local failure. MATERIALS AND METHODS: Retrospective analysis was done of patients with 19 carcinoma of the penis who were offered adjuvant chemotherapy with paclitaxel and platinum combination. The data regarding the surgical details, high-risk features for which chemotherapy was offered, chemotherapy toxicity details (in accordance with CTCAE vs 3), failure pattern, and survival data were noted. SPSS version 16 was used for statistical analysis. Descriptive and Kaplan–Meier survival analysis was performed. RESULTS: Median age of patients was 48 years. Fifteen patients received paclitaxel in combination with cisplatin and four received paclitaxel with carboplatin in view of their low serum creatinine clearance. The treatment was completed by 12 patients (63.2%). Of 79 planned cycles, 50 were taken. The treatment was well tolerated with grade 3-4 gastrointestinal toxicity was seen in 1 patient, grade 3 neurological toxicity in one and grade 5 neutropenia in one patient. Treatment related death occured in one patient. The median follow-up was 15.33 months and 6 loco-regional relapsed had taken place. The estimated median DFS was 16.2 months and the estimated median OS was not reached. The estimated DFS for treatment completed patients was 23.13 months as against 2.16 months for patients not completing treatment. CONCLUSION: The platinum and taxane doublet chemotherapy was found to be safe and effective.
