Annotated and tagged collection of microscopic images. Surgical material from patients with a histologically verified diagnosis (gastric adenocarcinoma) were used for routine staining with Hematoxylin and Eosin (H&E) or for immunophenotyping. IHC-staining for LMP-1 protein (Dako, clone CS.1-4) were used for Epstein-Barr virus (EBV) identification. The study of the cellular composition of the tumour tissue infiltrate was performed by immunohistochemical staining on the markers CD4 (clone 4B12), CD8 (clone C8/144B), CD68 (clone PG-M1) and CD1a (clone O10). Deparaffinization and antigen recovery was performed by using Thermo Dewax and HIER Bufer L, pH6 buffer. The preparations were studied by two independent researchers.
