[Effects of combination chemotherapy of ovarian cancer in vitro].

To investigate the effects of combination chemotherapy on ovarian cancer in vitro, we observed the sensitivity of tumors to different drugs by incorporation assay of tritium thymidine (3H-TdR). The results revealed that the drugs and their sensitive degrees varied from tumor to tumor. Whether the combination of the drugs is synergism or sometimes only enhances toxicity depends on the difference of individuals. We suggest that in vitro anti-cancer drug sensitivity test could be applied in selection or determination of chemotherapy protocol.
