Prognostic Indicators for Survival After Curative Resection for Patients with Carcinoma of the Stomach

This study aims to determine prognosticindicators among patient-, tumor-, and treatmentrelatedfactors of gastric cancer patients. A total of 510patients who underwent curative gastric resection were studied. Univariate analysis of patient-relatedfactors showed a significantly lower survival inpatients with a history of obstruction, hypoalbuminemia,and anemia. Tumor-related factors including gross appearance, location, and size of tumor; depthof cancer invasion; level, number, and frequency oflymph node metastasis; stromal reaction and tumor growthpattern; and histological classification allsignificantly affected survival. Surgical treatment relatedfactors such as total or distal subtotal gastrectomy,extent of lymphadenectomy, and combined resection ofadjacent organ(s) showed a statistically significant adverse influence on survival. Multivariateanalysis identified only four tumor-related factors— number of metastatic lymph nodes, depth ofcancer invasion, stromal reaction, and gross appearanceof the tumor — as independently affectingsurvival. These findings suggest that only fourtumor-related factors were prognostic indicators inpatients with gastric cancer.
