[Basic study on in vitro chemosensitivity tests].
By means of 3 different kinds of in vitro chemosensitivity testings--(1) a nuclear damage assay developed by us, (2) MTT assay, and (3) colony formation inhibition assay--we examined the sensitivity of 8 kinds of human ovarian cancer cell lines to various anticancer drugs. The sensitivity of in vivo xenografts of the cell lines in nude mice to anticancer drugs was also examined by inhibition of the tumor growth. The in vitro--in vivo correlation of sensitivity was studied in respect to both sensitivity and specificity rates. 1. Different active anticancer drugs were screened among the 3 in vitro chemosensitivity testings in the same human ovarian cancer cell line. 2. The in vitro--in vivo correlation of the nuclear damage assay (sensitivity 50%, specificity 94%) was the highest among the 3 testings. The nuclear damage assay which we developed therefore seemed to be the most useful assay method for clinical use.
