Patty, welcome to this forum. Very sorry to hear about you father-in-law. Hopefully, someone will come along to post that has some experience with this type of cancer, but wanted to let you know that, if an experienced post is slow in coming, it is because the majority of the people here are dealing with squamous cell cancer (at least that is my sense). But there are many folks here that can empathize with your difficult role as caregiver. Take good care of yourself, too.

Anita
