Gastroesophageal adenocarcinoma (GEA) and biliary tract cancers (BTC) may be challenging to treat and have suboptimal outcomes, especially if they are advanced. However, treatment targeting HER2, a protein on the surface of the tumor cells, can lead to better outcomes in tumors that overexpress this protein.
