Abstract
176 Background: The aims of the present study are to know the significance of curative surgery in Borrmann type IV and prove the causes related with poor prognosis by analyzing the recurrence patterns and unique diagnostic characteristics. Methods: We analyzed 168 patients with Borrmann type IV undergoing surgery at Seoul St. Mary Hospital from 1989 to 2010. We categorized the patients into curative (R0) and non-curative (R1, R2 and no-resection) group. Results: The numbers of curative and non-curative group were 91 and 77. The 3- and 5-yr OSRs of patients in curative group were significantly higher than those in non-curative group (curative: 52.4% and 33.0%, non-curative: 18.6% and 7.0%; p<0.001). In multivariate analysis, the curability was not a significant prognostic factor for survival (p=0.527). The most frequent recurrence site was peritoneum (64.7%). Most of recurrences were presented within early 2 years. The preoperative diagnostic rate of Borrmann type IV was only 50.5%. The reasons for non-curative surgery were unexpected peritoneal seeding (28.4%) and resection margin involvement (6.4%). Conclusions: The role of surgery for Borrmann type IV is quite limited. It has poor prognosis even after curative surgery, because it is very difficult to diagnose preoperatively and make curative surgery. [Table: see text]
