AIM: Main endpoint was a response rate to therapy; secondary endpoints were disease-free survival, overall survival, acute and late toxicities, specially in terms of anorectal and urinary continence. BACKGROUND: Radiochemotherapy for anal cancer achieves a good clinical response, locoregional control, anal function preservation. However, oncologic outcomes can differ using radiotherapy plus fluorouracil and mytomicin vs. cisplatin and fluorouracil. METHODS: Between 2000 and 2012, 27 anal cancer patients receiving radiotherapy combined with two different radiochemotherapy schedules, fluorouracil and mytomicin (group A) and cisplatin plus fluorouracil (group B). The Kaplan-Meier method was also used to estimate local control, overall survival and disease free survival. Statistical significance between curves was evaluated using the Log-rank test. RESULTS: Complete pathological response was found in 85.2% of patients, with higher rates of response in the group A (100% vs. 63.6%, p = 0.039). No significantly difference was found between the two groups for the other endpoints. Low rates of both acute and late toxicities were recorded. CONCLUSION: Radiotherapy plus fluorouracil and mytomicin provide a better complete pathological response than radiotherapy plus cisplatin and fluorouracil and a greater rate of anal sphincter function preservation. Globally, radiochemotherapy of the anal cancer provides excellent clinical outcomes with a good profile of acute and late toxicity, without difference between the two groups studied.
