[Antitumor effect of the tumor necrosis factor against various types of human cancer cells].
The antitumor activity of tumor necrosis factor (TNA) against various human cancer cells (32 cases) was investigated by 51Cr cytotoxic release assay and tumor stem cell assay. Over 50% sensitivity (the ratio of cytotoxicity for L929 cells) was shown by 4 of 14 cases of gastric cancer (28.6%), 7 of 9 cases of leukemic cells (77.8%), and 1 case each of pancreatic carcinoma and ovarian cancer. However, scarcely any sensitivity was shown by APL, a portion of the gastric cancer cells, normal lymphocytes or colony-forming cells tested. No correspondence was observed between the histological type of the cancer and TNF sensitivity. The above results seem to confirm the significant antitumor activity of TNF against human cancer cells.
