Objective: Ovarian mucinous tumors consist of benign, borderline, and carcinomatous tumor, but the clinical characteristics of these 3 types have not been investigated in detail. In this study, we compared the clinical characteristics and prognosis among these 3 types of mucinous tumors. Methods: One hundred sixty-one patients with mucinous cystadenocarcinoma and 143 patients with mucinous borderline tumor were registered between 1986 and 2003. All patients were reviewed by two pathologists, then the mixed type and cases showing other organized malignant tumors were excluded from this study. Patients with mucinous carcinoma staged Ib or more were treated postoperatively with 6 cycles of platinum-based chemotherapy. Survival probability was analyzed by the Kaplan-Meier method and differences in survival rates were calculated using log-rank test. Results: Mean patient ages were 43.9, 44.7, and 49.7 years in patients with benign, borderline, carcinomatous tumor, respectively. The ratio of early stage (I, II) to advanced stage (III, IV) was significantly lower in carcinoma than in borderline tumor. The levels of tumor markers tended to increase with the level of malignancy. CA72-4 is the most useful discriminating marker according to ROC analysis. In borderline tumor, 5 patients died of disease, and all of these patients had stage III disease with residual tumor after the initial surgery. Patients with borderline tumor showed significantly better prognosis than those with carcinoma; however, there were no significant differences in prognosis between borderline tumor and carcinoma in patients with stage III tumor or residual tumor. Conclusions: In mucinous tumors, measurement of CA72-4 is recommended to distinguish malignant from benign tumors. Even in borderline tumor, patients with residual tumor showed a poorer prognosis than carcinoma, suggesting that complete resection is necessary for a good prognosis.
