[Morphological manifestations of the immune reactions in stomach cancer and their relation to the histological structure of the tumor].
The morphology of immune response in tumor tissue was studied in the resected material obtained from 244 patients with stomach cancer. In nearly 80% of cases of carcinoma, the following five morphological types were observed: (1) acute inflammation (immediate--onset hyperergy); (2) time--delayed hyperergy; (3) plasmocytic--eosinophilic cellular infiltration with tumor mucination; (4) chronic granulomatous inflammation and (5) lymphadenoid and fibrose tissue envelope of tumor. There established a relationship between the type and degree of immune reactions and the histology of tumor. Progressing, regressing and stable reactions should be distinguished. Tumor regression and immune response were observed in foci; however, complete resolution was registered in 2.5% of cases only.
