taxotere and PSA

[CWT53]

adt stopped 9/22, daralutamide mono therapy until 7/23. Three rounds of docetaxel until 7/17/23. PSA rose from 4.9 to 5.1. PSMA scan showed decline in bone Mets. Tried a bit of fasting. Just switched to cabitaxel due to seeming failure of docetaxel based on PSA rise. Wondering if PSA increase was the result of fasting due to a small weight loss.

Question: Does PSA accumulate in fat so that fasting would release the additional antigen as indicated in the PSA increase that was inconsistent with the PSMA scan results?
