I just got an email from my favorite research nurse, Debbie in response to my question about tumor shrinkage percentage. She was going to have the radiologist give her the details. The report from the radiologist reads:

There is no measurable disease. There is a small 9mm tumor, which is less than 1 centimeter, which is called “non-measurable” disease which means it’s not measurable but is still present.

I believe the next steps are to have my 6th chemo, a PET scan and see what lights up and see if I need more chemo after that.
