title: [Regional transarterial infusion of autologous lymphokine-activated killer (LAK) cells for advanced renal cell carcinoma and its preliminary clinical result].
abstract: We herein report the preliminary but appreciable results of regional transarterial infusion of 2 gravity subtypes of autologous lymphokine-activated killer (LAK) cells into the metastatic sites in combination with systemic recombinant interleukin-2 (rIL-2) administration in 3 patients with advanced renal cell carcinoma. Leukapheresis was performed once a week and peripheral blood lymphocytes were separated into 2 different subtypes by Percoll gradient centrifugation. These lymphocytes were incubated with rIL-2 for a few days to induce LAK cells. LAK cells were transferred to the metastatic lesions through cannula twice a week. A large iliac bone metastasis disappeared 3 months after the initial LAK cell therapy via a superior gluteal artery. A case of complete disappearance of psoas muscle and para-aortic lymphnode metastasis as well as partial regression of a lumbar bone metastasis was seen after lumbar arterial infusion treatment. Another case with brain metastasis showed a rapid exacerbation of brain edema after one week's LAK therapy. Our treatment modality seems to be worthwhile and promising for treatment of the advanced renal cell carcinoma.
