A prognostic model based on the COL1A1-network in gastric cancer.

Background: Gastric cancer (GC) is one of the most common malignancies worldwide with a poor prognosis due to the lack of early detection and effective treatments. As a biomarker, collagen type I alpha 1 (COL1A1) is often dysregulated in some cancer types. However, the expression profile of COL1A1 and functional mechanism in GC is still unclear.
