PREOPERATIVE FACTORS OF PROGNOSTIC-SIGNIFICANCE IN GASTRIC-CANCER

This study was undertaken to investigate the ability of local anatomic al and primary histological features of gastric cancers, as well as DN A analysis, to predict prognosis. Using multivariate analysis, results indicate that location of a tumor in the gastric cardia, poor differe ntiation, involvement of adjacent organs, and aneuploidy are all indep endent predictors of survival. All of the factors studied can be deter mined by endoscopic procedures preoperatively on patients with gastric cancers and could be helpful in selecting some patients for periopera tive adjunctive therapies.
