RESUMEN
BACKGROUND: Early gastric carcinoma (EGC) is defined as a neoplasm confined to the mucosa and submucosa regardless of the presence of metastasis. This lesion is found in approximately 3% of cases in Mexico. The aim of this study is to describe our experience with EGC, emphasizing early detection as the most useful method to decrease mortality. METHODS: Retrospective review of records of patients with EGC treated at an oncologic referral center over a 12-years period. RESULTS: Twenty-one cases of EGC were retrieved. Mean age was 58.1 years (range, 33 to 84). Twelve were women and nine, men. Lymph node or distant metastasis were not found. Overall 5-year survival was 66.4%. Twenty patients underwent radical gastrectomy and only one underwent wedge resection of the gastric wall. Two patients (9.5%) presented recurrence and cancer-related death. Mean follow-up was 8.3 years. CONCLUSION: The prognosis of EGC in our hospital is lower than in countries other than Mexico and this lesion is found with low frequency. Increasing the detection EGC is the best method to reduce GC-related mortality.

BACKGROUND: Gastrectomy remains the only curative treatment for gastric cancer. However, surgical morbidity and mortality remains high. Our aim was to identify the risk factors that determine operative morbidity and mortality and to describe a simple method for preoperative stratification of morbidity outcome. METHODS: Retrospective review of patients who underwent gastrectomy for gastric cancer. Multivariate analysis was used to define risk factors for surgical morbidity and mortality. RESULTS: A total of 208 cases were included. Fifty-one episodes of operative morbidity and 19 surgery-related deaths were found. Operative blood loss (risk ratio [RR], 1.0012), serum albumin (RR, 0.42), extent of gastrectomy (RR, 2.8), lymphocyte count (RR, 0.999), and splenectomy (RR, 1.51) were the most important risk factors for morbidity. However, location of the tumor, serum albumin level, and lymphocyte count were the most important preoperative risk factors that determine the appearance of surgical complications. Receiver operating characteristic analysis of this model allowed definition of three risk groups in terms of surgical morbidity (11.8%, 28.5%, and 52.4%, respectively). CONCLUSIONS: A new method for preoperative calculation of the probability of surgical complications was developed. It must be validated prospectively and in different settings to be used in preoperative interventions designed to reduce that risk.
