      About half-way done with planned six-month course of Keytruda. Got scan results this week:

      ========

      1. Partial response to therapy with significant decrease in size of the mass posterior to C7 and near-complete metabolic resolution of the right upper back skin lesion.

      2. FDG avid focus within the posterior aspect of the left prostate is nonspecific on PET and could be due to focal prostatitis or malignancy. Please correlate clinically/lab results.

      ========

      Not sure how to take this. The possibiltiy of a second cancer (prostate) is concerning, though we know prostate cancer is (usually) very slow growing.

      Can a "partial response" turn into a "full response" later? Or once a partial always a partial?

          Of course it can turn into a complete response! Given the fact that you only had 4 rounds your response is amazing… it states partial because not all of it is gone… YET! 

          As for the prostate, it doesn't state definitely cancer, so try not to worry ahead of time, focus on beeing positive in regard to mel, cause your results so far are amazing!

          Take care,
