Thirty-five patients with clinically staged non-metastatic squamous carcinoma of the oesophagus were treated with radiation combined with mitomycin C, and 5-fluorouracil (5-FUra) infusion. Twenty patients were planned for a split course regimen 2250-2500 cGy in 10 fractions and chemotherapy. This dose of radiation to be repeated with another course of chemotherapy after 4 weeks rest. Fifteen patients were planned for a single course 4500-5000 cGy in 20 fractions and a single course of chemotherapy. Thirty-one patients are available for a minimum follow-up of one year, 26 patients for a minimum follow-up of 2 years. All 35 patients are included in the survival and local relapse-free analysis. Survival at one year is 47% and at 2 years 28%. The local relapse-free rate at both one and 2 years is 48%. There was an improvement in survival and local relapse-free rate for the single course regimen compared to the split course; 2 years survival 48% versus 12% (p = 0.24) local relapse-free rate 79% versus 27% (p = 0.07). All patients receiving radiation and chemotherapy were compared with historical controls treated by radiation alone. This matching procedure was done independent of knowledge of outcome (two controls were matched/case). Patients were matched for age, sex. TNM stage, and total radiation dose. There was a significant difference in survival p = 0.004 and local relapse-free rate p = 0.05 for patients receiving radiation and chemotherapy.(ABSTRACT TRUNCATED AT 250 WORDS)
