TREATMENT OF PATIENTS WITH MALIGNANT PLEURAL EFFUSIONS DUE TO ADVANCED LUNG CANCER BY TRANSFER OF AUTOLOGOUS LAK CELLS COMBINED WITH rIL-2 OR rIL-2 ALONE

摘要

Experimental study both in vitro and in vivotogether with clinical trials showed that LAKcells have antitumor and antimetastatic effects(1-5)and that these effects are closely related tothe number of LAK cells transferred and the ad-ministration of rIL-2(1,6-8).Usually,autologousPBL’s are used as the source of LAK precursorsin the adoptive immunotherapy of cancer patients.But this not only puts an added burden on thecancer patient,it can cause serious side effectsas well(9).Although TIL’s may provide a solu-tion to this problem(10,11),their isolation fromsolid tumors is complex and consumes many rea-gents.We have reported that the isolation oflymphocytes from malignant ascites or from ma-lignant pleural effusions is not only simple
