ABSTRACT

PURPOSE:

Ovarian conservation is controversial in patients with cervical adenocarcinoma due to the risk of ovarian metastasis. The aim of this study is to evaluate the association of ovarian conservation with survival outcomes in young patients with T1N0M0 cervical adenocarcinoma.

METHODS:

Women who were 45 years of age or younger with T1N0M0 cervical adenocarcinoma from 1988 to 2013 recorded in the Surveillance, Epidemiology, and End Results (SEER) database were included. Propensity score weighting was used to balance the intragroup differences. Cause-specific survival (CSS) and overall survival (OS) were compared using Kaplan-Meier estimates. A multivariate Cox model was used to adjust for covariates including propensity score. A stratified analysis was then conducted.

RESULTS:

Totally, 1090 (79.7%) patients underwent oophorectomy and 278 (20.3%) patients whose ovaries were preserved were identified. Patients with preserved ovaries were younger, with a lower T classification and less likely to undergo pelvic lymphadenectomy (all p < 0.05). After propensity weighting, ovarian conservation group had better cause-specific survival (CSS) (5-year 98.8 versus 97.1%, 10-year 98.0 versus 95.2%, p = 0.0370) and overall survival (OS) (5-year 98.8 versus 97.1%, 10-year 96.5 versus 93.5%, p = 0.0025). After adjustment, the CSS benefit of ovarian conservation was marginally significant (p = 0.051) and OS benefit was still significant (p = 0.006). Stratified analysis showed that the CSS benefit was found in T1b classification (HR, 0.23; 95% CI 0.06-0.89, p = 0.033) and histological grade > 1 (HR 0.12; 95% CI 0.02-0.87; p = 0.035).

CONCLUSION:

Among young women with T1N0M0 cervical adenocarcinoma, ovarian conservation is associated with better survival.
