Gastric cancer: correlation between clinicopathological factors and survival of patients. II.

Abstract

"Signet-ring" cells carcinomas, and the anaplastic ones, prove in our study to be extremely aggressive histological forms, characterized through low rates of survival. We remarked a significant correlation between the degree of tumor differentiation and survival of patients, the values recorded being significantly lower in medium and poorly differentiated carcinomas (p = 0.00871194 FS). Average survival, calculated in months, is significantly lower in patients with diffuse type carcinomas (11.3 months), in comparison with patients presenting intestinal type carcinomas (20.4 months) (p = 0.0415 S). There is a direct proportional relationship between the lymphovascular invasion and the number of positive lymph nodes. Survival after 5 years decreases significantly in the presence of lymphovascular invasion.
