Abstract

PURPOSE: This study was designed to investigate the clinicopathologic factors related to peritoneal recurrence and to predict peritoneal recurrence based on clinicopathologic factors.
METHODS
A retrospective analysis of 383 patients with peritoneal recurrence, out of 4184 patients who had undergone curative gastric resection at SNUH from 1986 through 1996 was done.
RESULTS
Of the patients with peritoneal recurrence, 275 (71.8%), 97 (25.3%), and 11 (2.9%) were early (0~24 months), intermediate (24~60), and late (more than 60) recurrence, respectively. In multivariate analysis, serosal invasion, lymph node metastasis, size of tumor, Borrmann type, perineural invasion and sex were independent prognostic factors for peritoneal recurrence. After classifying all patients into 16 groups on the basis of 4 factors, serosal invasion, lymph node metastasis, Borrmann type, and size, the number and proportion of a patients with peritoneal recurrence was obtained. There was 4.2% peritoneal recurrence in the most favorable group (n = 71), which had a Borrmann type 1 or 2 lesion less than 5 cm in maximal diameter with neither serosal invasion nor lymph node metastasis. There was a 25.4% peritoneal recurrence in the most unfavorable group (n = 331), which had a Borrmann type 3 or 4 lesion more than 5 cm with serosal invasion and lymph node metastasis.
CONCLUSION
Our results suggest that patients with a Borrmann 3 or 4 lesion more than 5cm in maximal diameter, with serosal invasion and lymph node metastasis have thehighest risk for peritoneal recurrence. These patients could be considered as candidates for a treatment modality such as intraperitoneal chemotherapy or hyperthermic chemotherapy.
