Abstract

Concomitant radiochemotherapy is the standard treatment of squamous cell carcinoma of the anal canal. It can afford a high local control rate though the same impact has not been observed on survival. A few reports have concerned the impact of local control on distant metastases and survival. From 1988 to 1998 at the "Divisione di Radioterapia" of the "Università Cattolica del S. Cuore" of Rome 30 patients with squamous cell carcinoma of the anal canal were treated for cure. Treatment consisted of two cycles of radiotherapy (23.4 Gy) with a 4-5 week split in each cycle. 5FU (100 mg/sqm/24 h) was administered in continuous infusion for the first 4 days of therapy; mitomycin C (10 mg/sqm bolus) was administered on day 1, 4-6 weeks after the end of cycle 2 of concomitant radiochemotherapy, patients received a boost of interstitial brachytherapy. Local control on T of all patients was 84% at 5 years. Six patients showed locoregional recurrence: 3 recurrences on T and 4 disease progressions in locoregional lymph nodes. 3 of 6 patients underwent salvage surgery. The initial extent of the disease, the patient's age and brachytherapy boost did not have a statistically significant influence on local control. Two of the 30 patients showed liver metastases, and at their appearance, one patient was free of local disease while the other showed locoregional progression after Miles' operation for salvage. The metastasis-free interval was not significantly influenced by local control, although at 5 years, 96% of patients with local control of T were free of metastases vs 75% of those with recurrence on T (p = 0.22). Overall actuarial survival at 5 years was 75%. The behavior of survival in our experience seemed to be significantly influenced by local control: in the group with local control, 5-year survival was 85% vs 40% of patients with local recurrence (p = 0.01).
