摘  要:从12例骨肉瘤患者手术切除的实体瘤中分离肿瘤浸润淋巴细胞(TIL),从患者引流淋巴结中分离淋巴细胞(LNL),以rIl—2激活培养,并以4小时51Cr释放试验测定TIL和LNL体外抗瘤活性。结果表明:12例骨肉瘤患者的TIL培养15~25天,对K562和LiBr靶细胞(效靶比25∶1)平均杀伤活性分别为59.7±12.6%和44.2±10.2%,激活的LNL对K562和LiBr细胞的杀伤活性分别为55.2±11.6%和40.8±9.1%,二者对K562和LiBr细胞杀伤活性相差不显著(P>0.05)。其中6例患者TIL和LNL对自身肿瘤细胞杀伤活性分别为38.8±9.5%和35.5±7.6%,二者相差不显著(P>0.05)。Tumorinfiltrating Iymphcytes (TIL) and Iymph node Iymphocytes (LNL) were respectively separated from tumor cells in resected solid tomors and drain of lymph node in 12 patients with osteosarcoma.The TIL and LNL were cultivated in the presence of rIL2 for 15~20 days,and their antineoplastic activity in vitro was detected by four hour 51 Cr releasing assay.The results showed that the average killing activies of rIL2activated TIL and LNL to the target cells K562 and LiBr lines were 59.7±12.6%,44.2±10.2%and 55.2±11.6%,40.8±9.1%,respectively,the ratio of effctor cells to target cells being 25∶1.There was no significant difference in killing activity between the TIL and LNL (P>0.05).In 6 of the 12 patients,the killing activities of TIL and LNLto autologous tumor cells were 38.8±9.5% and 35.5±7.6% respectively,and also no significant difference between TIL and LNL(P>0.05).It was indicated that LNL activated by rIL2 have the same killing activity as TIL.It would provide a reference for clinical treatment of tumor patients with LNL.
