Brachytherapy in oesophageal carcinoma.

Patients with recurrent or locally advanced oesophageal carcinoma have a poor prognosis. Relief of dysphagia is often the goal of any further treatment. Several methods, including laser re-canalization, prosthetic intubation, dilatation, external beam irradiation (EBI) and intraluminal brachytherapy (IBT) can be used to alleviate dysphagia. In this retrospective review of 11 patients, eight with recurrent tumour and three newly diagnosed patients were treated with low dose rate IBT. Relief of dysphagia was achieved in nine patients, all of whom were able to maintain swallowing of at least a semi-solid diet until death or last follow-up. Toxicity was minimal, but survival was poor, with a median survival of only 3 months. IBT presents several advantages over other palliative methods, especially in recurrent tumours where re-treatment with EBI is often difficult because of normal tissue tolerance. Low dose rate IBT takes only 1-2 days to deliver, is highly effective, has little morbidity and the palliation achieved is relatively durable.
