High-dose-rate intraluminal brachytherapy for esophageal cancer: 10 years experience in Hyogo College of Medicine.
From May 1980 through December 1989, 148 patients with thoracic esophageal cancer were treated with high-dose-rate intraluminal brachytherapy (HDRIBT) following external radiotherapy (ERT). The standard treatment protocol was 60 Gy/6 weeks of ERT and 12 Gy/1 week of HDRIBT. The patients were divided into two groups according to disease stage. Sixty-six patients had limited disease (LD), and 82 patients had extensive disease (ED). The 2-year survival rate was 37% in LD group, and 7% in ED group. The 5-year survival rate of LD group was 18%. The 1- and 2-year actuarial local control rate was 66% and 64% in LD group, and 49% and 45% in ED group, respectively. In the total patients, ulceration, stricture, and fistula were found in 42 (28%), 15 (10%) and 6 (4%) patients, respectively; however, major complication defined as one resulting in a second hospitalization or requiring surgical intervention was 3 of the 42 patients with ulceration, 1 of the 15 patients with stricture, and all of the six patients with fistula. As to cause of death, local failure, local failure with distant metastasis, distant metastasis, intercurrent disease, and unknown reason was 14, 6, 15, 16 and 0 in LD group, and 13, 24, 30, 9 and 1 in ED group, respectively. The technique and method of combined treatment are described in detail.
