Abstract

Objective: To determine the relative effect and quantify the impact of multiple prognostic variables on median overall survival time among cohorts of patients with advanced or recurrent endometrial cancer undergoing cytoreductive surgery. Methods: Fourteen retrospective cohorts with advanced or recurrent endometrial cancer (672 patients) meeting study inclusion criteria were identified. Univariate analysis was used to assess the effect on median overall survival time of multiple variables. The limited number of studies available made multivariate analysis impractical. Results: Statistically significant clinical variables associated with median overall survival time were the proportion of patients undergoing complete surgical cytoreduction, adjuvant radiation, or receiving adjuvant chemotherapy. Cohort median overall survival time was positively associated with increasing proportion of patients undergoing complete surgical cytoreduction (each 10% increase improving survival by 9.3 months, p = 0.04) and receiving post-operative radiation therapy (each 10% increase improving survival by 11.0 months, p = 0.004), while an increasing proportion of patients receiving chemotherapy was negatively associated with survival (each 10% increase decreasing survival by 10.4 months, p = 0.007). Conclusions: The current analysis suggests that among patients with advanced or recurrent endometrial cancer, complete cytoreduction to no gross residual disease is associated with superior overall survival outcome. The unexpected correlation between treatment modality and survival may be a surrogate marker for more precise factors such as location of disease, performance status, or cytoreductive status post-operatively, which may have influenced the decision to administer adjuvant radiation versus chemotherapy and were not able to be controlled for given the limitations of the extracted data.
