The conditions and the treatment
Gastric cancer is another name for cancer of the stomach. Advanced gastric cancer means that it has spread to nearby tissues, or has come back in another part of the body some time after you were first treated.
Gastro–oesophageal junction adenocarcinoma is cancer that develops at the point where your food pipe (oesophagus) joins your stomach.
Ramucirumab is a type of therapy called a monoclonal antibody, that may stop the cancer growing.
