Ovarian Cancer Chemotherapy

The current standard regimen for advanced ovarian cancer is paclitaxel (Taxol) and the platinum compound carboplatin. Alternatives are docetaxel (Taxotere) with carboplatin or paclitaxel with cisplatin, another platinum compound. Recent clinical trials found no difference in survival between patients receiving carboplatin with either docetaxel or paclitaxel, but the docetaxel/ carboplatin group had a greater incidence of myelosuppression. Those receiving paclitaxel/carboplatin had more neuropathy. Newer drugs being combined with carboplatin and paclitaxel are topotecan, liposomal doxorubicin, and gemcitabine.
The Gynecologic Oncology Group (GOG), a research group funded by the National Cancer Institute, is currently conducting a clinical trial for high-risk early-stage disease comparing three cycles of paclitaxel/carboplatin followed by surveillance versus paclitaxel alone weekly for 24 weeks. The GOG is also proposing a clinical trial on the use of carboplatin and paclitaxel combined
with bevacizumab to treat advanced ovarian cancer.
