Abstract
Whether chemoradiotherapy (CRT) is clinically beneficial for the management of postoperative recurrence of advanced gastric cancer remains unclear. We retrospectively studied treatment outcomes in patients who had unresectable localized recurrence after surgery for advanced gastric cancer and evaluated the safety and efficacy of CRT. The study group comprised 21 patients who received concurrent CRT for unresectable localized recurrence after undergoing R0 resection for stage II/III advanced gastric cancer. Localized recurrence was defined as a few or limited recurrent lesions. The recurrence pattern was anastomotic recurrence in 7 patients, abdominal lymph-node recurrence in 12, and anastomotic recurrence plus abdominal lymph-node recurrence in 2. The median total dose of radiotherapy was 48.6Gy (range 39.6-56.0), and the CRT completion rate was 100% (21 of 21 patients). CRT-related grade 3 or higher toxicity comprised neutropenia in 33.3% of patients and anorexia in 9.5%. The response rate was 61.9% (complete response 38.1%, partial response 23.8%). The median overall survival was 35.0months. We conclude that CRT may become one treatment strategy for the management of unresectable localized recurrence after curative resection of advanced gastric cancer.
