Metastatic Bladder cancer & Padcev w/ Keytruda success

I'm dealing with BC that has metastasized to my thoracic lymph nodes. It reappeared in ct DNA within 3 months of stopping immunotherapy. I was all clear until that point after a RC in Nov 2024 etc). Sometimes things don't go as we plan them.

I'm starting round 3 (of forever) with Keytruda and Padcev. I'm more fatigued than I expected but my body is trying to figure out its new normal.

Has anyone taken P&K after metastasis? What was your experience? Did you feel a little better after a few rounds, did you see positive results?
