Good morning Miriam. Thank you for the valuable information. Wow, 23 years, that’s impressive. You undoubtedly are a fighter and an inspiration to us. I’m going to press my Dr to buck the current 2 year limit and try a maintenance protocol. We’ll see what happens. A PET scan in Dec. showed a small hot spot, 1/2 inch size, in my good lung and radiation cleaned it up. I am now cancer free and remaining on immunotherapy/Keytruda 400cc every 6 weeks until June. Keep up the good work.
