Abstract:

Objective:
To evaluate the impact of ovarian preservation on overall survival in young women with early-stage endometrial cancer.

Design:
Retrospective and meta-analysis.

Setting:
Two medical centers.

Patient(s):
A total of 203 patients diagnosed with endometrial cancer (≤45 years) from 2000 until 2010.

Intervention(s):
Patients who underwent oophorectomy versus those whose ovaries were preserved.

Main Outcome Measure(s):
The overall survivals were compared. Independent factors that may affect the patients’ survival were extracted and analyzed. A meta-analysis of the literature was carried out to further validate the findings.

Result(s):
Of 203 young patients, 169 patients (83.3%) underwent bilateral salpingo-oophorectomy, 20 patients had both ovaries preserved, and 14 patients had a single ovary preserved. Multivariate logistic regression identified intraoperative extrauterine disease as the most significant risk factor of ovarian involvement. A Kaplan-Meier curve and Cox proportional hazards models analyses found that ovarian preservation had no effect on overall survival. The findings were validated by meta-analysis.

Conclusion(s):
Ovarian preservation has no statistically significant impact on the overall survival of young patients with early-stage endometrial cancer. The ovaries should be preserved in this specific population after a thorough preoperative evaluation and an extensive intraoperative exploration.
