Information for the public

Pembrolizumab (Keytruda) is not normally available on the NHS for untreated locally advanced unresectable or metastatic HER2-positive gastric (stomach) or gastro-oesophageal junction adenocarcinoma. Your doctor should talk with you about other treatment options. If you are already having it, you should be able to continue until you and your doctor decide when best to stop.
