title: Induction chemotherapy with carboplatin and 5-fluorouracil in combination with radiotherapy in loco-regionally advanced epidermoid carcinoma of the anus--preliminary results.
abstract: During the last decade conservative treatment of anal carcinoma based on radiotherapy has gained popularity. Radiotherapy is often combined with concurrent chemotherapy although no firm evidence exists that such combinations are more effective than radiotherapy alone. Treatment results with respect to anal sphincter function are generally better for small tumors. In an effort to improve the treatment results for locally advanced epidermoid anal carcinoma, a selection of patients with such tumors has been treated with induction chemotherapy comprising two or three courses of a combination of carboplatin 300-350 mg/m2 i.v. and 5-fluorouracil 1,000 mg/(m2 x d) x 5 d prior to radiotherapy. Six female patients aged 37 to 74 have completed the regimen. All had complete tumor regressions at conclusion of radiotherapy. No recurrence has yet occurred but the follow-up period is still short (8-21 months). No interruption of chemotherapy due to toxic side effects was necessary and no severe toxicity registered. Further study is needed to evaluate the efficacy and toxicity of the regimen, but these early findings are promising.
