Combined chemotherapy--radiotherapy of anal cancer.
Forty-five patients were treated from 1984 to 1988. Thirty-eight, with a minimum follow-up of 6 months, are considered evaluable: median age, 62 years (25-88); males 6, females 32; T1 = 7, T2 = 21, T3 = 10; inguinal positive nodes, 5 patients. Chemotherapy (CT) (Mitomycin C, 15 mg/sqm, bolus day 1; 5-FU, 750 mg/sqm, 24 hr infusion, days 1 to 5) and radiotherapy (RT) started the same day. A dose of 36 Gy was given to the tumor and to the pelvis including inguinal nodes, in 20 fractions. After 2 weeks a boost of RT (18 Gy) to the ano-perineal area and a second cycle of CT completed the treatment. CR (biopsy) was achieved in 32/38 patients (84.2%). Among the six patients on PR, four received a Miles operation (2 NED), and two a wide local resection (both NED). Five out of 32 CRs relapsed: 2/5 were rescued with a Miles resection, 3 died from progression. In conclusion, 32/38 patients (84.2%) are NED after a median follow-up of 22 months and 28 of them retained their anal sphincter. A longer follow-up is needed to define optimal treatment modality, but it is clear that surgery must play a minor role in the treatment of anal cancer.
