Prognostic indicators for survival after curative resection for patients with carcinoma of the stomach.
This study aims to determine prognostic indicators among patient-, tumor-, 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 significantly lower survival in patients with a history of obstruction, hypoalbuminemia, and anemia. Tumor-related factors including gross appearance, location, and size of tumor; depth of cancer invasion; level, number, and frequency of lymph node metastasis; stromal reaction and tumor growth pattern; and histological classification all significantly affected survival. Surgical treatment related factors such as total or distal subtotal gastrectomy, extent of lymphadenectomy, and combined resection of adjacent organ(s) showed a statistically significant adverse influence on survival. Multivariate analysis identified only four tumor-related factors-number of metastatic lymph nodes, depth of cancer invasion, stromal reaction, and gross appearance of the tumor-as independently affecting survival. These findings suggest that only four tumor-related factors were prognostic indicators in patients with gastric cancer.
