Malignant peritoneal cytology and decreased survival of women with stage I endometrioid endometrial cancer.

ABSTRACT:

Background

To examine the association between malignant peritoneal cytology and survival in women with early-stage endometrioid endometrial cancer.

Methods

This is a retrospective cohort study using the Surveillance, Epidemiology, and End Results Program from 2010 to 2016. Women with stage I endometrioid endometrial cancer who had peritoneal cytology testing at hysterectomy were examined (N = 24,800). Characteristics and survival related to malignant peritoneal cytology were assessed. The propensity score inverse probability of treatment weighting was used to balance the measured covariates.

Findings

Malignant peritoneal cytology was reported in 1081 (4.4%) women. In multivariable analysis, stage IB disease and moderately/poorly differentiated tumours were associated
