I have hep C, and didn't even know I had it until the CCC I was at requested that I be screened. I had Cisplatin and didn't have any liver issues. They will monitor liver enzyme levels as a precaution. There are several of us here with hep C.
I wouldn't let them pull my teeth. The teeth and gums HAVE to be in good shape to withstand the treatment however.
One thing you forgot to mention about PBT is that they typically use IMRT with it as well. I would have strongly considered PBT if I had it to do over again. MD Anderson feels strongly enough about it to invest 200 Million in a new facility just for it.
Here is a link for information about PBT for those interested:
http://www.llu.edu/proton/ or
http://www.proton-therapy.org/ We also recommend across the board to always go to a comprehensive cancer center. This disease doesn't like to give second chances. If nothing else at least have them review the case. You must act fast - they typically won't touch it once treatment has started.
It normal for low red and cell counts as a result of the treatment. He can get Procrit and blood transfusions if necessary.
Hearing loss is a RARE adverse effect of Cisplatin. There will be distinct warning signs first and it can be halted before permanent damage. Many of us here suffered temporary hearing loss due to the radiation impact on the eustacian tubes which is a different issue. They should do a baseline hearing test PRIOR to treatment.
Remember that we all respond differently to treatment. There are some here that drove themselves to treatment every day and continued working. People talk about radiation burns on the neck and that varies widely also - I had a mild sunburn and that was it. Don't live in fear of what hasn't happened yet.
I recommend getting a book "Living Well With Cancer" by Katen Moore and Libby Schmais. It was written by oncology nurse practitioners. It answered about 98% of my questions as I went through the treartment and side effects. If you click on the Amazon link on the link below OCF will get a small benefit from this.
