Abstract

A 76-year-old male patient underwent a distal gastrectomy for advanced gastric cancer. As the postoperative serum CA19-9 level was elevated, chemotherapy was initiated. Computed tomography(CT)detected a solitary peritoneal recurrence in the left subhepatic space 17 months later. Consequently, chemoradiotherapy(CRT)at a total dose of 60 Gy, combined with S-1 therapy, was administered for local tumor control. After CRT, CT scans revealed a remarkable reduction in the peritoneal recurrence. Presently, 8 months after CRT, the patient remains alive with no indications of regrowth. CRT could prove efficacious as a treatment for gastric cancer patients with localized peritoneal recurrences.
