Measuring relief of dysphagia in locally advanced esophageal carcinoma patients submitted to high-dose-rate brachytherapy.

Esophageal neoplasm has a poor prognosis, and palliative care remains an important goal of treatment. The purpose of this study was to assess the ability of high-dose-rate brachytherapy (HDRB) to improve dysphagia in 115 patients treated at our institution.Patients previously submitted to external beam radiotherapy that at least, 1 month after, presented with residual disease and persistent dysphagia, were given HDRB as palliative treatment. Patients with tumors extending to the level of cardia and those with cervical esophageal lesions were also eligible. HDRB consisted of three fractions of 500 cGy given weekly. Dysphagia was assessed using a food texture-based scale classified according to the type of food patients were able to swallow (absent, solid, pasty, or liquid). At the end of treatment, a single-category shift in dysphagia classification was scored as +1 (e.g., liquid to pasty) or -1 (e.g., solid to pasty), and a dual-category shift was scored as +2 (e.g., liquid to solid) or -2 (e.g., absent to pasty).Most patients (51.1%) had improvement of dysphagia, and 55.3% of this group experienced one-point improvement. Procedural complications included stricture (38.2%), bleeding (7%), and fistula (8.7%). In the present study, 13 patients with cervical esophageal lesions underwent HDRB without fistula formation.Esophageal HDRB effectively reduces dysphagia. Tumor location was not related to development of complications.
