ATP—生物荧光法在肿瘤体外药物敏感性试验中的应用研究

为探讨ＡＴＰ－生物荧光法在肿瘤体外药敏试验中应用的可行性，采用该法对小鼠纤维瘤细胞株Ｌ９２９，卵巢癌新鲜组织和腹水细胞进行抗癌药物处理后的细胞活性测定。结果显示：该法能测出不同浓度药物对细胞作用的剂量－效应关系，以及不同个体对不同浓度药物反应的差异，实验变异系数ＣＶ值为１．２％￣１５．８％，在培养的第５天药物处理组与对照组差异最大，检测效果最好，用混和酶液消化，可有效地制备含〈３０个细胞团块的单细

An evaluation of adenosine triphosphate bioluminescence assay for tumor in vitro chemosensitivity testing]

This study was aimed at the feasibility of using ATP-bioluminescence assay for tumor in vitro chemosensitivity testing. With the use of this assay, the authors determined dose-response curve in mouse fibroma cell line L929 treated with chemotherapeutic agents, and investigated the different in vitro responses of 6 ovarian carcinomas (5 from fresh tumor tissues, 1 from ascites) treated with etopside, cis-plating, 5-fluorouracil and adriamycin. The results showed that the coefficients of variation for triplicate assays ranged from 1.2% to 15.8% which means high reproducibility of the assay. The single cell suspension (including < 30 cells clusters) could be separated from tissue fragments by means of enzyme cocktail (collagenase, Dnase, pronase). The viable cells were over 90%. This study demonstrates that ATP-bioluminescence assay is a sensitive, reliable and efficient method for tumor chemosensitivity testing. In this connection, the correlation between in vitro drug sensitivity and in vivo patient response is worth further studying.
