PROGNOSTIC INDICATORS FOR SURVIVAL AFTER CURATIVE RESECTION FOR PATIENTS WITH CARCINOMA OF THE STOMACH

This study aims to determine prognostic indicators among patient-, tum or-, and treatment-related factors of gastric cancer patients. A total of 510 patients who underwent curative gastric resection were studied , Univariate analysis of patient-related factors showed a significantl y lower survival in patients with a history of obstruction, hypoalbumi nemia, and anemia, Tumor-related factors including gross appearance, l ocation, and size of tumor; depth of cancer invasion; level, number, a nd frequency of lymph node metastasis; stromal reaction and tumor grow th pattern; and histological classification all significantly affected survival, Surgical treatment related factors such as total or distal subtotal gastrectomy, extent of lymphadenectomy, and combined resectio n of adjacent organ(s) showed a statistically significant adverse infl uence on survival. Multivariate analysis identified only four tumor-re lated factors-number of metastatic lymph nodes, depth of cancer invasi on, stromal reaction, and gross appearance of the tumor-as independent ly affecting survival. These findings suggest that only four tumor-rel ated factors were prognostic indicators in patients with gastric cance r.
