[Clinicopathologic analysis of ovarian serous and mucinous borderline tumors]
1Department of Pathology, Jiangxi Women and Children's Health Hospital, Nanchang 330006, China.
Objective:
To understand the clinicopathological features of ovarian borderline tumors and evaluate the significance of various histological appearances.
Methods:
Forty-five patients with borderline tumors were analyzed retrospectively. The stage distribution was stage I, 34 patients, stage II, 4 patients and stage III, 7 patients.
Results:
Forty-five cases of borderline tumors accounted for 25.4% of ovarian epithelial malignant tumors. The ratio of serous borderline tumors (SBTs) to mucinous borderline tumors (MBTs) was approximately 1:1.3. Nine of eleven SBTs with exophytic growth presented peritoneal implants, of which two were invasive and seven noninvasive. Two SBTs and 1 MBT recurred after 5, 4, and 1 years respectively. Thirty-three cases were followed from 2 to 9 years. The 5-year survival rate was 100% (Kaplan-Meir method).
Conclusions:
The prognosis of the SBTs is favorable. SBTs with exophytic growth are often associated with peritoneum implants.
