| Research Abstract |
In these several years, we applied LAK induced from thoracic duct lymphocytes to patients with recurrent malignant tumor. Nine patients were treated had LAK induced from thoracic duct lymphocytes and/or peripheral blood lymphocytes. Gastric, breast or pancreatic cancer did not show tumor regress. Three colorectal cancer did not show tumor growth during LAK treatment. One hepatoma case with hepatic, iliac bone and lung metastases showed complete tumor necrosis of hepatic metastasis, however, LAK was ineffective for the iliac bone and lung metastases. Immunohistochemical stain revealed that beta2 microgobulin (BMG) was positive on the cell surface of hepatic metastasis and negative in iliac bone and lung metastatic site. BMG was a small component of major histocompatibility complex class 1 antigen. Our results suggested a possibility that LAK might contain cytotoxic Tlympohcytes or induce them. Until now, we tried to make much more amount or more cytotoxic LAK, but now we investigate again about the antigen presentation on target cell surface and the relation about application and cytotoxic effect of LAK.
