I have been in a study nivo/dacarbazine for 12 weeks now. I have hoped that I got nivo but my new MR showed progress so I am out of the study. My MM is in sinus maxillaris and masseter, upper yaw, palatine bone are involved and its growing next to the scullbase. I have had max radiation in this area a few years ago when my MM first started in my nose cavity. So radiation nor surgery is an option. Probably I will get ipi now. I have been told that I will never know which arm I was in. If MM proceed they assume I got dacarbazine. I am quite upset and depressed now but feel a lot of comfort visiting this forum.
