Clinicopathologic characteristics, survival, and treatments for gastric adenosquamous carcinoma: a population-based study.

ABSTRACT:

Background

Gastric adenosquamous carcinoma (gasc) is a rare entity with distinctive characteristics that are not fully understood. In the present study, we evaluated the characteristics of this rare disease.

Methods

The U.S. Surveillance, Epidemiology, and End Results program database was searched to determine the clinicopathologic features, prognostic factors, and treatments for 246 patients with gasc and 42,735 patients with gastric adenocarcinoma (gac).

In patients who underwent potentially curative surgery (pcs), gasc was associated with a higher proportion of radiotherapy use and p
