I'm glad to hear you have had positive results from your treatments. That must have be awful to have gallbladder surgery inbetween your treatments too. I seem to recall my doctor told me I had the ATM mutation when I had my biopsy & genetic test of my tumor. I was told in October there wasn't any targeted treatment for the ATM mutation at the time. I was also supposed to go on maintenance chemo too but my cancer markers have started to rise now that I'm on G-A. I'm really happy for you. Hope things continue in the right direction. Take care.
