Background: The aim of this study is to determine efficacy and feasibility of the combination regimen irinotecan and cisplatin in patients with cisplatin advanced penile cancer.
Patients and methods: Patients with T3, T4, N1, N2, N3 or M1 cisplatin advanced penile cancer were treated with a combination of irinotecan (60 mg/m2) on days 1, 8 and 15 and cisplatin (80mg/m2) administered every 28 days. Patients were treated either in the neo-adjuvant setting for T3 or N1–N2 disease with a maximum of four cycles before surgery or up to eight cycles for T4 or N3 or M1 disease. The study was designed with the aim to exclude a response rate (complete response + partial response) <30% (
= 10%, power = 95%).
Results: Twenty-eight patients were included and evaluated for toxicity, and 26 eligible patients were evaluated for response. Toxicity was acceptable with three cases of grade 3 diarrhoea and two cases of grade 4 neutropenic fever. There were eight responses (two complete response and six partial response) (30.8%, 80% confidence interval 18.8% to 45.1%): three patients undergoing histological verification after chemotherapy had no evidence of malignancy.
Conclusion: The study fails to demonstrate a response rate significantly >30%.The observation regarding M0 patients suggests to repeat this study in the neo-adjuvant setting.
