The purpose of this study is to study efficacy and the effects on quality of life in women with ovarian cancer treated with a weekly schedule of chemotherapy with carboplatin and paclitaxel compared to those treated with standard every 3 weeks schedule of the same chemotherapy.

The standard first-line treatment of ovarian cancer is combination chemotherapy with carboplatin and paclitaxel, given every 3 weeks. Researchers are looking at new ways of giving chemotherapy to make it more tolerable and more effective. One way is by giving the chemotherapy more often in smaller doses. This approach can be associated with fewer or less troubling side effects. Some chemotherapy drugs such as paclitaxel have been shown to also be more active when given once a week rather than once every 3 week schedule.
