@jaxthecat I had also been going every 6 weeks w/o any incident after the inital few treatments at 3 weeks. My treatment has been on hold since Sept when I experienced some significant GI issues that may or may not be Keytruda related - I'm having another GI biopsy next week to try to determine if Keytruda played a role - so when I meet with my oncologist on the 22nd I'll see if I can resume immonotherapy and if so, if I go back to every 3 weeks or maintain the 6.

Glad the 3 week schedule is working out for you. Are you anticipating a 2 year treatment plan?
