AIM: To analyze the outcomes in @entity788 ( @entity788 ) cases with a microscopically-positive resection margin (R1 resection) treated with postoperative radiotherapy (PORT). @entity1 AND METHODS: We retrospectively analyzed the outcomes in 62 @entity1 who received PORT for @entity788 with R1 resection between 2001 and 2012. All @entity1 received three-dimensional conformal radiotherapy. Concurrent chemotherapy was administered to 58 @entity1 . RESULTS: The median follow-up was 20.1 months. The median survival was 22.0 months and the 3-year overall survival rate was 25%. The 3-year disease-free survival and local recurrence-free survival rates were 12% and 54%, respectively. Local recurrence occurred in 23 @entity1 (44%), distant failure in 45 (87%), and both in 16 (31%). By multivariate analysis, the postoperative cancer antigen 19-9 (CA19-9) level and adjuvant chemotherapy were independent prognostic factors for survival. CONCLUSION: PORT is associated with a relatively favorable survival outcome in @entity788 with R1 resection. Chemotherapy and postoperative CA19-9 level were significant prognostic factors for survival.
