title: Comparison of the sister chromatid exchange and cell survival assays as a measure of tumor cell sensitivity in vitro to cis-diamminedichloroplatinum (II).
abstract: Cytotoxic effects of treating RIF-1, EMT6, and 9L tumor cell lines with cis-diamminedichloroplatinum(II) were measured with the sister chromatid exchange assay and compared to results obtained with the colony-forming efficiency assay. The greatest number of sister chromatid exchanges was induced in RIF-1 cells, fewer in EMT6 cells, and the least in 9L cells. Cell survival data obtained with the colony-forming efficiency assay paralleled data obtained with the sister chromatid exchange assay. These studies suggest that the sister chromatid exchange assay may be a useful method with which to determine the in vitro sensitivity of tumor cells to some antineoplastic agents.
