[Immunologic studies on the patients with gastrointestinal cancer--with particular reference to correlation between T lymphocyte and macrophage].
Correlation of monocyte with T lymphocyte or IgG-FcR+ T lymphocyte was studied in 57 gastrointestinal cancer patients and 24 healthy volunteers as control. In 24 volunteers, no correlation was found between them. Forty gastrointestinal cancer patients with curative tumor showed pre-and postoperatively a close correlation between monocyte and T lymphocyte, but there was little correlation, both pre-and postoperatively, between monocyte and IgG-FcR+ T lymphocyte. Seventeen patients with recurrent and/or inoperable gastrointestinal cancer, had a reverse correlation of monocyte with IgG-Fc R+T lymphocyte. It was suggested from these data that mononuclear phagocyte system (monocyte), which fulfils its function as an antigen presentation, has an intimate relationship, both directly and indirectly, to T lymphocyte.
