Abstract

Aim: To assess feasibility, complications and efficacy of induction chemotherapy followed by standard chemoradiotherapy in patients with bulky anal canal cancer. Patients and Methods: Patients with squamous cell carcinoma of the anal canal, staged bulky tumor with or without nodal involvement were prospectively enrolled. Before standard chemoradiotherapy, patients received induction chemotherapy with 3 cycles of 75 mg/m2cisplatin and 750 mg/m25-fluorouracil. Patients were followed-up routinely until recurrence or death. Results: Seven patients with bulky anal canal cancer were evaluable for this pilot phase of the study. All patients had human papillomavirusnegative disease. Five completed the scheduled induction chemotherapy and all patients completed the programmed concomitant chemoradiotherapy. None had severe hematological toxicity. The majority of patients (6/7) had tumor downsizing after induction treatment. Six months after chemoradiotherapy, complete response was documented in three patients and salvage surgery was performed in two cases. With a median follow-up of 38 months (range=28-48 months), two patients are disease-free survivors. Conclusion: Induction chemotherapy has the potential to become a standard approach in patients with bulky human papillomavirus-negative anal canal cancer.
