Palliative therapy for esophageal cancer: laser therapy alone is associated with a better functional outcome.

Abstract

The aim of our study was to compare functional outcome and survival in patients who underwent laser therapy (LT) or laser therapy and esophageal stenting (LTES) to palliate inoperable esophageal cancer. Two hundred and twenty-seven consecutive patients who had endoscopic palliation for esophageal cancer were enrolled in this retrospective study. One hundred and sixty-four underwent LT alone and 63 had LTES. A dysphagia score was adopted (0: absolute dysphagia; 1: liquid diet; 2: semisolid diet; 3: free diet). Survival analysis and non parametric statistics were performed. Patients in the LTES group reported a significantly worse dysphagia score than LT patients (p<0.01). LTES patients more frequently reported difficulty swallowing than LT patients (p<0.01). No difference between LTES and LT groups was observed in terms of overall survival. Only radiotherapy resulted in a significant predictor of better survival (p=0.007). Despite a similar survival, LTES is a predictor of a worse functional palliation than LT alone. Radiotherapy was associated with better survival in patients treated with LT. Therefore, these data seem to suggest that a combination of endoscopic LT and external radiotherapy may yield the best results in palliative care of advanced esophageal cancer.
