I have been on Keytruda treatment alone for 21 months with 19 infusions for Kidney cancer. Up until recently the only side effect that I had was skin rash; I am 83 year old male. However, about one month ago a routine blood test done by primary doctor showed fasting blood glucose had spiked to 113, and A1C had gone from 5.6 to 5.7. A subsequent blood test done at oncologist office showed glucose was still at 103. I am scheduled for another infusion middle of February, but I have decided that the chance of a serious reaction from Keytruda is too great and will not continue. I have a CT scan in two weeks; the last four months ago was good.

@ronsale: It’s admirable you track your lab results so closely. While I understand concerns about increasing glucose levels to what is generally considered pre-diabetes range, I’m wondering if it’s significant enough to warrant discontinuing treatment at what I imagine is nearly the end of your treatment. Perhaps more frequent monitoring of blood sugars would be considered in the interim?

It’s certainly your choice, however such a decision would probably be worthy of a more in-depth conversation with your medical provider first. Have you had such a conversation to hear their perspective?
