I haven't posted anything for a while. I started Keytruda late July, 400mg every 6 weeks. . My only initial side effects were fatigue and an episode of atrial fibrillation a couple of weeks after each infusion. In January I developed colitis, probably grade 2. The January infusion (my 5th) was cancelled and I had a course of prednisone. A colonoscopy showed all clear, so my next infusion was 2/18. I also have several very minor side effects, which I ignore.

My scans have been confusing. The October scan said the right lung nodule was resolving. But the January one said it was 1.3 cm, which was the original size. So I guess it's stable rather than resolving. I assume the next scan will be in late April or May. My next infusion is 4/1.
