Hello
My husband has the amplification of the pathway and was in the trial that used herceptin and perjeta. He was in the trial 8 months. The 2 lesions on the liver remained stable but the one on the abdominal wall grew 20% and forced him from the trial. He was another trial after that ,immunotherapy, which shrunk the tumor on the wall but the liver lesions grew. Currently on chemo gemcitabin and abraxane.
