Fight hard for faster action, and get that genomics (Foundation One) testing ASAP. If she has a mutation type that is favorable to a Keytruda class drug, that is a possible solution. My wife passed away last month of extrahepatic cc after a 4 year battle. Long long story. But I’m afraid my wife’s was caught earlier in the progression based on your description. Ultimately Janet succumbed because there was no drug to treat her mutation type. I’m hoping and praying your mom can get lucky.
