PURPOSE: The aim of this study was to retrospectively observe gastric adenocarcinoma patients with postoperative oligometastatic recurrence and investigated the effects of concurrent involved-field radiotherapy (RT) and XELOX on progression-free survival (PFS). PATIENTS AND METHODS: From 2008 to 2011, 246 patients underwent curative resection of gastric carcinoma was enrolled. A retrospective review was performed on 34 patients with distant recurrence. Among them, 19 patients were oligometastases patients, where 13 patients received involved-field RT with a dose of 40-60 Gy by an intensity-modulated RT technique and concurrent XELOX chemotherapy, four patients were treated with XELOX chemotherapy alone (oxaliplatin 130 mg/m2, capecitabine 1000 mg/m2, twice daily, 3 week each cycle), and two patients with only brain metastasis were not included in the analysis. RESULTS: The median PFS was 11 months in the 13 oligometastatic patients who received concurrent involved-field RT and XELOX. The oligometastatic patients receiving concurrent radiochemotherapy trended toward a better median PFS when compared with those receiving chemotherapy alone. CONCLUSIONS: For patients with postoperative oligometastatic recurrence, concurrent involved-field RT and XELOX showed better responses and was a choice for first-line treatment.
