Abstract

Purpose: The purpose of this study was to analyze the clinical courses of patients with gastric cancer and positive resection margins after a gastrectomy for gastric cancer who did not undergo subsequent surgery. Materials and
Methods: Among 4,452 patients who underwent surgery for gastric cancer from January 2001 to December 2007, 20 patients with positive resection margins after gastrectomy for gastric cancer who did not undergo subsequent surgery were included. The recurrence patterns were confirmed by postoperative computed tomography and gastroscopy, which were performed on a planned schedule. All recurrence patterns after gastrectomy were classified as loco-regional, peritoneal, or distant metastases.
Results: The patients with confirmed recurrence all had advanced stage cancer (III?IV), and the recurrence sites were variable. However, peritoneal and distant recurrences were more common than loco-regional recurrences. The patients with loco-regional recurrence also had peritoneal and/or distant recurrence.
Conclusions: Patients with gastric cancer and a positive resection margin showed more frequent peritoneal and distant metastases than loco-regional recurrence. In addition, patients with loco-regional recurrence also had peritoneal and distant recurrence. A positive resection margin of gastric cancer was related with poor histological differentiation, diffuse type, and advanced stage (III?IV).
