Özet

Objective: To evaluate the prognostic factors affecting overall survival (OS), disease-free survival (DFS), and survival among patients undergoing chemoradiotherapy (CRT) for locally advanced gastric carcinoma. Methods: Between January 2001 and May 2014, 257 patients who presented to our clinic with a diagnosis of stage I-IIIC gastric cancer were evaluated. The male/female ratio of the cases was 2.02: 1 and the median age was 55.16 +/- 11.8 (20-80) years. Four of the cases (1.6%) were stage IA, 13 (5.1%) were stage 1B, 41 (16%) were stage IIA, 40 (15.6%) were stage IIB, 50 (19.5%) were stage IIIA, 51 (19.8%) were stage IIIB, and 58 (22.6%) were stage IIIC. Results: The mean follow-up time was 22.5 months (3.3-155.0); loco-regional recurrence was noted in 34 (13.2%) patients who underwent postoperative chemoradiotherapy, and metastases were observed in 108 (42%) patients. The median OS duration was 26.7 months (95% confidence interval, 20-33.5) and the 2-, 5-, and 10-year OS was 52.8% (standard error [S.E.] 0.032), 36.1% (S.E. 0.032), and 26.9% (S.E. 0.034) respectively. The median DFS was 53.7 months and the 2-, 5-, and 10-year DFS were 58.9% (S.E. 0.034), 47.4% (S.E. 0.037), and 40.7% (S.E. 0.042), respectively. In multivariate analysis of prognostic factors, advanced T stage (p<0.0001), advanced nodal stage (p=0.001), and surgical margin status (p<0.0001) were related to decreased OS and DFS. Conclusion: R1 resection, advanced T stage, and advanced nodal stage were adverse prognostic factors in gastric cancer patients who had undergone CRT after the operation.
