[Cytotoxic activity of large granular lymphocytes (LGL) infiltrated into metastatic tumors of lung cancer].
Large granular lymphocytes (LGL) showing Leu 7 and weak E rosettes were separated from two metastatic tumors of lung cancer. Weak cytotoxic activity of these cells was recognized against autochthonous tumors, but never against K-562 cells. After OK-432 therapy, this cytotoxicity was not enhanced, but antibody dependent cell-mediated cytotoxicity (ADCC) of peripheral blood mononuclear cells of the patient was induced against metastatic tumors. These signs may suggest that specific immunotherapy should be available for these cancers.
