      Hi fellow warriors,

      Just finished my first month on Keytruda, and results are real good. The tumor on my neck shrunk significantly, there’s hardly anything left of that little animal.

      But I been reading about on PDL1 expression and its use as a prognostic indicator. 50 percent and above is a real good indicator immunotherapy will be effective and the prognosis is much better.

      Mine was 5 percent. My doctor said that’s good enough. He also said depending when the expression was taken, before immunotherapy or after, the percentage would be different. If done after, the percentage would be higher. Mines was taken before. Anyone else here have any experience with this you can share? Thank you!
