OBJECTIVE: The aim was to compare survival in pure and mixed-type advanced clear cell ovarian carcinoma and to determine the benefits among patients with pure advanced clear cell ovarian carcinoma treated in paclitaxel-platinum-based chemotherapy in comparison with those treated in conventional platinum-based chemotherapy after primary surgery. METHODS: Between 1994 and 2001, 31 women with stage III and IV pure clear cell ovarian carcinoma and nine patients with stage III and IV mixed-type clear cell carcinoma were identified from the tumor registry of six institutions. All patients underwent cytoreductive surgery followed by conventional platinum-based chemotherapy or paclitaxel and platinum-based chemotherapy. RESULTS: The median survival of women with pure clear cell carcinoma was 11 months, compared to 48+ months for those with mixed-type clear cell carcinoma (P = 0.003). Overall, for women with pure clear cell carcinoma, 35% had clinically complete responses to chemotherapy. For women with pure clear cell carcinoma treated with paclitaxel-platinum-based chemotherapy, the median survival was significantly longer than for those treated with conventional platinum-based chemotherapy (16.26 vs. 10.75 months, P = 0.045; with optimal cytoreduction, 40.95 vs. 9.02 months, P = 0.028). Univariate analysis showed paclitaxel-platinum-based treatment was the only favorable prognostic factor for women with advanced pure clear cell ovarian carcinoma (P = 0.05). CONCLUSIONS: Patients with advanced pure clear cell ovarian carcinoma have poorer prognoses than those with the mixed type. Paclitaxel-platinum-based chemotherapy improved survival among our patients with advanced pure clear cell carcinoma, especially for those with optimal cytoreduction.
