Between September 1987 and September 1993, 88 patients with oesophageal cancer were treated by a single session of intraluminal brachytherapy of 15 Gy prescribed at 1 cm distance from the central axis, using MDR Cs-137 (n = 51) during the first part of the study and HDR Ir-192 (n = 37) during the second part of the study. All patients were regarded as inoperable. Improvement of dysphagia, assessed 4-6 weeks after treatment, was noted in 50 of 75 (67%) evaluable patients, whereas swallowing ability was completely restored in 47% of them, Relapse of dysphagia occurred in 28 (37%) patients during follow-up. Additional palliative treatment consisted of endoprosthesis in 14 (19%), a second course of brachytherapy in 13 (17%), one or more dilatations only in 11 (15%) and laser treatment in four (5%) patients. One non-fatal haemorrhage and five fistulae occurred, all in the presence of tumour. Two severe ulcerations without evidence of tumour were noted, both managed by combined curative treatment. The median survival of the group investigated was 5.5 months. An exophytic, non-circular growth pattern was associated with a better response. In a multivariate analysis the presence of distant metastases (p = 0.0028), weight loss (p = 0.0051) and an exophytic growth pattern (p = 0.0199) were associated with a worse survival. The present data indicate that a single session of ILB is appropriate in the palliation of dysphagia in patients with inoperable oesophagal cancer showing bad prognostic signs. Up to now there has been no clear evidence for benefit of addition of ERT.
