Currently, adjunctive therapy for gastric cancer is not standardized worldwide and the most effective combination of different modalities has not been clearly determined. The aim of the present study was to retrospectively analyze the efficacy and toxicity of the combination of perioperative epirubicin, capecitabine and oxaliplatin (EOX) chemotherapy and postoperative concurrent chemoradiotherapy in the treatment of locally advanced gastric cancer. A total of 41 patients with locally advanced gastric cancer who had undergone perioperative EOX chemotherapy and surgical resection followed by chemoradiotherapy, were assessed. The perioperative EOX regimen consisted of 50 mg/m2 epirubicin and 130 mg/m2 oxaliplatin on day 1, with 625 mg/m2 capecitabine administered twice daily on days 1-21. The perioperative regimen was repeated 2‑3 times every 3 weeks. After complete resection following the perioperative EOX regimen, concurrent chemoradiotherapy with capecitabine (4,500 cGy in daily fractions of 180 cGy administered 5 days per week for 5 weeks, with 625 mg/m2 capecitabine twice daily during radiotherapy) and 2 cycles of the EOX regimen 4 weeks after radiotherapy, were performed. In total, 30/41 patients (73.2%) completed all the planned treatments, including perioperative chemotherapy, surgical resection and chemoradiotherapy. The effective rate of preoperative chemotherapy (partial and complete response) was 56.1%; 30/41 patients received R0 resection, and the overall 3-year survival rate was 57.7%. Grade 3/4 gastrointestinal toxicity (nausea/vomiting) occurred in 22% of the patients, while 18 patients (43.9%) developed grade 3/4 hematological toxicity (granulocytopenia). The results of the present study indicated that the combination of perioperative EOX chemotherapy and postoperative concurrent chemoradiotherapy is feasible and effective for locally advanced gastric cancer.
