作者对１２例肾癌组织标本肿瘤浸润淋巴细胞（ＴＩＬ）的抗瘤活性进行了研究。结果显示，自１２例肾癌标本中１０例成功地分离到ＴＩＬ，经４周培养平均扩增８５．９２倍，表型分析以Ｔ淋巴细胞为主，随培养时间延长Ｔ４比率逐渐减少，Ｔ８比率逐渐增加，培养后ＴＩＬ抗瘤活性显著增强但对自体肿瘤细胞特异杀伤问题需进一步研究，初步结果表明ＴＩＬ治疗肾癌具有可行性。
The authors studied the antitumor activity of tumor infiltrating lymphocytes (TILs) in 12 cases of renal cell carcinoma. The results showed that TIL was successfully isolated from 10 cases of renal cell carcinoma in 12 cases and amplified 85.92 times on average after 4 weeks of culture. The T lymphocytes were the main phenotypes, and the ratio of T4 decreased with the increase of culture time. T8 The ratio increased gradually, the TIL anti-tumor activity was significantly enhanced after culturing, but the specific killing of autologous tumor cells needs further study. The preliminary results show that TIL is feasible for treating renal cell carcinoma.
