BACKGROUND AND PURPOSE:Intravoxel incoherent motion MR imaging can simultaneously measure the diffusion and perfusion characteristics of brain tumors. Our aim was to determine the utility of intravoxel incoherent motion-derived perfusion and diffusion parameters for assessing the treatment response of metastatic brain tumor following gamma knife radiosurgery.

This study reviews the clinical outcome and prognosis of patients with malignant mixed müllerian tumors (MMMTs) of the ovary treated with optimal cytoreductive surgery, leaving no residual disease, and platinum-based chemotherapy. Ten patients diagnosed with MMMT of the ovary after complete surgical staging from February 1993 to February 2004 at Asan Medical Center in Korea were studied retrospectively. All ten patients were treated with optimal cytoreductive surgery, leaving no gross residual disease. Seven patients received ifosfamide/cisplatin chemotherapy, and the remaining three patients received other platinum-based combination chemotherapy. Demographic data, pathologic findings, treatments, and survival time were reviewed. Of the ten patients, two were scored at FIGO stage IIC, seven were at stage IIIC, and one was at stage IV. The median survival time of all ten patients was 46 months. The overall survival rate was 60.0% at 1 year, 40.0% at 2 years, and 20.0% at 5 years. Platinum-based combination chemotherapy after optimal cytoreductive surgery may be effective in the treatment of ovarian MMMT.
