Objective: To determine the disease free and overall survival at two years in patients with gastric cancer who received adjuvant treatment in the Colombian National Institute of Cancerology (INC) during 2009. Patients and methods: A retrospective study was conducted on patients with a diagnosis of a gastric adenocarcinoma or of the gastroesophageal junction and who had received adjuvant chemotherapy in the INC during the year 2009. The variables recorded were: clinical and epidemiological characteristics, treatment received, and the overall and disease free survival at two years. Results: A total of 32 patients (56.2% males), with a mean age of 55 years were included in the analysis. The most predominant histological sub-type was intestinal (53.1%). T3-T4 tumor invasion grade was present in 81.2%, and lymph involvement in 84.3%, with 34.3% of cases with seven or more lymph nodes involved. Almost all of them (96.8%) received adjuvant treatment according to the Macdonald protocol. Three-quarters (75%) of the patients completed the treatment. Treatment was stopped in 12% of cases due to toxicity. The mean follow-up of the patients was 37.8 months. The overall and disease free survival was at two years in the patients who received adjuvant chemotherapy was 85.18% and 77.4%, respectively. Conclusions: The study showed a greater overall and disease free survival in patients who received adjuvant treatment in the INC compared to that found in patients in the INT 0116 and MAGIC studies. The survival is similar to that in studies with Asiatic populations.
