Relaitonship between area of serosal invasion and prognosis in patient with gastric carcinoma

Abstract

We examined the relationship between the spatial extent of invasion of the gastric serosa in patients with gastric carcinoma and their postoperative 5‐year survival rate. At the time of surgical resection of gastric patients with gross evidence of serosal invasion. Examination of the relaitonship between the presence of with an area of serosal invasion 10 cm2 or less were positive for free cancer cells, but such cells were found in 72% of cases with an area of serosal invasion greaer than 20 cm2. The 5‐year survival rate was 31% in patients iwht ana area of serosal invasion of less than 10 cm2, whereas the rate was only 8% in patients witha n area of serosal invasion greawter than 20 cm2. Not only the presence of serosal invaison by a tumor but also the spatial extent of the invasion are significant factors that ainfluence the prognosis of patients wiht gastric carcinoma.
