@songinmyheart54 Interesting. So in your case they are treating Keytruda as a long term drug that may fend off melanoma, but if you stop the chances of melanoma coming back are likely. I never imagined any of the immunial therapy drugs to be a permanent medication. That would get very expensive in a hurry. I know one treatment is close to 23,000 us dollars every 6 weeks. 400 mg. Thanks for your response.

@songinmyheart54: Have you gotten a response from Melissa at AIM at Melanoma? Just an FYI in my particular case as I had to suspend Keytruda for my metastatic melanoma - for which there is currently no evidence of disease - due to toxcity and in consideration of some other conditions I have - but both my oncologist and a seminar led by oncologists from Sloan Kettering I've attended have indicated that chemotherapeutic agents, such Dacarbazine or a group known as taxanes could be considered should my melanoma recur. It may be worth exploring as opposed to remaining on immunotherapy indefinitely, which is certainly your choice.
