Abstract
Between 9/80 and 9/83, 20 patients with esophageal carcinoma were treated with combined radiotherapy and chemotherapy (5-FU and mitomycin). Thirteen patients with Stages I or II disease received definitive treatment consisting of 6000 rad in 6-7 weeks and 5-FU (1000 mg/m2/24 hours) as a continuous I.V. infusion for 96 hours starting on days 2 and 28. Mitomycin (10 mg/m2) was administered as a bolus injection on day 2. Palliative treatment (5000 rad plus above chemotherapy) was delivered to six patients with Stage III disease (two with extra-esophageal spread, four with distant metastases) and to one patient with an anastomotic recurrence following resection. Two of 13 definitively treated patients were not evaluable due to early death from intercurrent disease. Ten of 11 evaluable patients treated definitively are alive from 4-32 months; the median survival has not been reached at 17 months. Four of 11 evaluable patients treated definitively have relapsed, with only one relapsing within the irradiated field. Among the palliative and definitively treated patients, relief of dysphagia was seen in 16/17, and continued until the time of last follow-up or until death in 13/17. The treatment was well tolerated and no significant hematologic problems were incurred. This combination of radiation therapy with infusional 5-FU and mitomycin appears to be an effective and well-tolerated regimen in the treatment of esophageal carcinoma and is worthy of further study.
