Abstract |
The response of ovarian serous papillary adenocarcinomas to various cytotoxic drugs was examined using the (3-(4,5-dimethylthiazol-2-yl)-5-(3-carboxymethoxyphenyl)-2-(4-sulfophenyl)-2H-tetrazolium, inner salt) (MTS) cytotoxicity assay. Thirty tumors were collected and organized into four groups according to histologic grade and FIGO stage: stage III, grade 2; stage III, grade 3; stage IV, grade 2; and stage IV, grade 3. The MTS chemosensitivity assay was performed on each tumor to examine the response to cisplatin, paclitaxel, hycamtin and the combination of cisplatin and paclitaxel. Ovarian adenocarcinomas of similar stage and grade displayed varying responses to the same drug. A lower concentration of the drug was often as effective as the peak plasma concentration. For some specimens combination therapy was more effective for inhibiting tumor growth, and for others single-agent therapy gave a better response. A chemosensitivity/resistance profile is recommended before deciding on appropriate chemotherapy.
