摘要: The purpose of this study was to compare the growth-inhibitory effect cisplatin–paclitaxel with that obtained a cisplatin–docetaxel combination and assess type interaction. Concomitant use taxanes cisplatin studied in seven human ovarian carcinoma cell lines, using 96-well plate clonogenic assay. Chemosensitivity expressed terms IC50 values, drug concentration causing 50% inhibition survival. interaction area under survival curve ratios (AUC ratios) by numerical integration. Comparison AUC ratio surviving fraction (SF) value after taxane alone made Student’s t-test. influence tested one-way analysis variance (Anova). A supra-additive or additive seen when lines were exposed paclitaxel docetaxel concomitantly cisplatin. found four (UT-OC-3, UT-OC-4, UT-OC-5 SK-OV-3) simultaneous all concentrations tested, two (UT-OC-4 used paclitaxel. more pronounced docetaxel. degree supra-additivity dose dependent, increasing synergy higher dose. data suggest can be achieved concomitant taxane.
