Endoscopic scoring of late gastrointestinal mucosal damage after adjuvant radiochemotherapy.

摘要

AIM: To evaluate late effects of chemoradiation on gastrointestinal mucosa with an endoscopic scoring system and compare it to a clinical scoring system. METHODS: Twenty-four patients going to receive chemoradiation after gastric surgery underwent endoscopy four wk after surgery and one year after the chemoradiation finished. Upper gastrointestinal findings were recorded according to a system proposed by World Organisation for Digestive Endoscopy (OMED) and clinical scoring was done with RTOG-EORTC radiation morbidity scoring systems. RESULTS: There was no significant endoscopic difference in gastric and intestinal mucosa after chemoradiation (P > 0.05) and there was no association between endoscopic scores and clinical scores. Endoscopic changes were minimal. CONCLUSION: Late effects after chemoradiation in operated patients with gastric cancers can be evaluated with an endoscopic scoring system objectively and this system is superior to clinical scoring systems.
