Internal audit of oncological results in gastric cancer surgery.

INTRODUCTION: National information on the oncological results of gastric cancer surgery is scarce, so foreign figures are used, which may completely differ from local ones. The aim of our study is to analyse these results in the patients operated on in our centre. METHODS: Survival results of 134 patients that underwent gastric cancer surgery with curative intent from 2004 to June 2016 were analysed. RESULTS: A percentage of 76.8 of the patients (103/134) presented in advanced clinical stages (≥ii). Staging laparoscopy was performed in 67% of them (69/103), an extensive lymphadenectomy (≥LD1+) was carried out in 89.3% of patients (92/103), and 76.7% (79/103) received perioperative chemotherapy. The distribution by pathological stage 0, i, ii, iii and iv was 8.2, 20.2, 26.1, 37.3, and 8.2%, respectively. Median follow-up was 87 months. Median OS was 68 months and one-, 3- and 5-year OS were 81.2, 62, and 53.8%, respectively. The 5-year OS according to pathological staging was 100% for stage 0, 88.4% for stage i, 62.5% for stage ii, 23.6% for stage iii and 17% for stage iv. CONCLUSIONS: Our survival rates are in the high ranges of western literature. These results could not be compared with national ones due to the lack of information regarding oncological outcomes in gastric cancer surgery in our closest environment.
