Why the study?
Gastric tumors generally have a poor prognosis, and molecular markers to improve early detection and predict outcomes are greatly needed.
Periostin is highly expressed in gastric tumors and promotes metastasis and invasion, suggesting its potential as a diagnostic or prognostic biomarker and therapeutic target.
POSTN overexpression may aid gastric tumor identification; leaves open prospective validation for clinical adoption.
