From April 1966 to April 1986, 101 men and women with unresectable squamous cell carcinoma of the esophagus were treated in our clinic. Since 1983, 21 were treated with a combination of hyperthermia, chemotherapy, and radiotherapy (group I). Before 1983, for another 80 patients, radiation plus chemotherapy had been prescribe (group II). Nine of 21 patients in group I had an unresectable carcinoma due to an advanced tumor, 9 had an associated severe clinical status, and 3 refused surgery. Out of 80 in group II, 50 had a far advanced tumor, 21 had a poor clinical condition, and 9 refused operation. With regard to staging, for 21 in group I, 6 were classified as Stage I, 5 as Stage II, 7 as Stage III, and 3 as Stage IV. As to the 80 in group II, those in Stage I, II, III, and IV accounted for 8, 22, 39, and 11, respectively. The median doses of each modality, for patients in group I, were 6 times of hyperthermia at 42–45°C for 30 minutes, 40 Gy of X ray and 30 mg of bleomycin. For patients in group II, a median dose of 56 Gy of X ray was given. Response rates determined by esophagograms and endoscopies for the patients in groups I and II were 76.2% ( 16 21 ; 4 CRs,12 PRs) and 39.2% ( 31 79 ; 2 Crs, 29 PRs), respectively ( p < 0.001). The effective rates determined by improvement in quality of life (relief of pain and dysphagia) for groups I and II were 61.9% and 37.2%, respectively. A longer survival was obtained for patients in group I (median survival: 9 months vs 6 months). Especially for the patients classified as Stage I, a significantly longer survival was obtained with a combination of hyperthermia, chemotherapy, and radiotherapy ( p < 0.01).
