Despite the high objective response rate of patients with advanced epithelial ovarian cancer to combination cisplatin and paclitaxel-based chemotherapy, the majority of individuals ultimately develop disease recurrence. Thus, new agents or treatment strategies are required to substantially improve the long-term disease-free survival potential in this malignancy. One of the most characteristic features of ovarian cancer is the intraperitoneal distribution of disease that commonly accompanies the diagnosis. Therefore, intraperitoneal (IP) chemotherapy is a reasonable approach in the treatment for ovarian cancer, and it has been extensively investigated both pre-clinically and clinically. There are several studies comparing intraperitoneal versus intravenous cisplatin-based chemotherapy. Although all of the trials have shown survival benefit of intraperitoneal chemotherapy, this approach has not been accepted as a standard treatment for select ovarian cancer patients. Intraperitoneal carboplatin & topotecan should be considered as high priority in the future studies.
