How Gastric Cancer studies are organized in the registry

Gastric cancer studies are often registered together with gastroesophageal junction (GEJ) tumors, and many list both. HER2 status appears in this portfolio as well, marking a biomarker-defined subset. Including “gastroesophageal” in a query surfaces records that a plain “gastric” search can miss.

Terms that often appear in related listings
gastroesophageal junction GEJ HER2 advanced gastric

These describe how studies tend to be titled and grouped on ClinicalTrials.gov — they are search vocabulary, not medical guidance.
