Abstract

BACKGROUND

Clear-cell carcinoma of the ovary (CCC) is often diagnosed at childbearing age, or sometimes during treatment for infertility. Therefore, most young women with early-stage CCC wish to preserve their reproductive and endocrine functions if possible.

METHODS

Clinicopathologic data collected under the central pathological review system were subjected to survival analyses. We analyzed patients with stage I CCC who underwent fertility-sparing surgery (FSS, n = 16) and compared their long-term survival with those receiving radical surgery (n = 205), or patients with non-CCC undergoing FSS (n = 64).

RESULTS

There was no difference in both the overall survival (OS) and disease-free survival (DFS) between patients with CCC who underwent FSS and those who received radical surgery [CCC/FSS (n = 16) versus CCC/radical (n = 205); OS: P= 0.519, DFS: P= 0.265]. Moreover, patients with CCC who underwent FSS did not show a poorer OS and DFS than non-CCC patients who underwent FSS (CCC/FSS versus non-CCC/FSS; OS: P= 0.584, DFS: P= 0.401), or those at the corresponding stage with no CCC. Furthermore, according to the series of patients with CCC in both the current study and four studies in the literature, there was no difference in the recurrence rate between patients with or without CCC who were treated conservatively (CCC/FSS: 13.2% versus non-CCC/FSS: 10.9%, P= 0.614).

CONCLUSIONS

Although our study did not have sufficient power to yield a definite conclusion, our data suggests that at least patients with stage IA CCC may be treated with FSS.
