The optimal neoadjuvant and adjuvant treatment for gastric cancer remains controversial. We conducted a phase II study using preoperative chemotherapy with modified FOLFOX6 followed by surgical resection and postoperative chemoradiation in patients with gastric carcinoma. Preoperative chemotherapy (two or three cycles) consisted of a 2-h infusion of oxaliplatin (100 mg/m2) and folinic acid (100 mg/m2) followed by a 46-h continuous infusion of 5-fluorouracil (5-FU; 2,400 mg/m2).
