Palliative resection or radiation of primary tumor prolonged survival for metastatic esophageal cancer.

ABSTRACT:

Purpose

We aimed to explore the value of palliative resection or radiation of primary tumor for metastatic esophageal cancer (EC) patients.

Methods

Surveillance, Epidemiology, and End Results database was used for identifying metastatic EC patients. The patients were divided into resection and nonresection groups. And patients without resection were divided into radiation and nonradiation groups. Propensity score matching (PSM) analyses were adopted to reduce the baseline differences between the groups. Cancer specific survivals (CSSs) and overall survivals (OSs) were compared by Kaplan-Meier (K-M) curves. Multivariable analyses by COX proportion hazards model were performed to identify risk factors for CSS and OS. Predictive nomograms were conducted according to both postop
