title: [Antimetastasis effect of lymphokine-activated killer (LAK) cells on fibrosarcoma in WKA rats].
abstract: Treating WKA rats with fibrosarcoma with LAK cells, antimetastasis effect was studied. The results indicated that splenocytes incubated by IL-2 could produce lytic activity to WKA rats with fibrosarcoma in vitro. Passive infusion of LAK cells lead to a marked reduction in the number of metastatic nodules in the lung. After intravenous injection of LAK cells, cancer cells in the lung speedily disappeared. LAK cell administration for 3 times gave better result than once only (P less than 0.01). In this paper, the possibility of LAK cells used as an adoptive immunotherapy for human neoplasms is briefly discussed.
