My dad has stage 4 prostate cancer, diagnosed in August of 2022. Gleason 4+3
Stage 4 because it went to 1 lymph node in the abdomen. After 44 rounds of radiation, receiving Eligard injections every 3 months, and 10 months on Apalutamide, his scans show no evidence of disease. ( As of Oct 2023)
His PSA is. 06 as of October, 2023 with his testosterone being at 17.
He got some blood work today, and his PSA is still .06 but his testosterone has risen to 34. Is this a cause for concern? Also, it looks like anemia might be a new thing, low hemoglobin. Does this mean that the ADP isn't working anymore even though the PSA is down?
Any input is welcome. Thank you!
Mortality Probability after first PSA rise vs non-castrate testosterone levels (low vs Normal)
Climbing psa but low testosterone 
PSA DECLINING WHILE IT WAS RISING
Confused - Psa declined testosterone increased 
Rising PSA after radiation and ADT
