[Morphologic evaluation of the effectiveness of local immune reactions in gastric cancer]

Upon the analysis of 50 cases of cancer of the stomach, the authors compared the size and composition of stromal cellular infiltrate, the size of active vascular bed in the tumor, mitotic activity of the tumor cells, the severity of regression in adenocarcinomas and signet ring cell polymorphocellular carcinoma of the stomach. The authors established the necessity of a comprehensive investigation of the tumor parenchyma and specificities of parenchymal blood supply for determination of local immune response in the tumor in relation to its efficiency.
