My husband was diagnosed in Jan. 2022 by his Urologist for Stage 3b Highly Aggressive (label they gave it) prostate cancer, Gleason score of 8, into seminal vessicles, but no mets seen on PET Scan. Received Lupron for 18 months and Casodex 50mg was initiated immediately and continued once a day for 2 mos. Then he received 45 tx of radiation ( 5x wk for 9 wks ).
With the Lupron, he experience hot flashes and sweats, night and day, mild, but noticeable loss of muscle strength, but this didn't affect his function. Although off the Lupron, he still gets the sweats at times. He feels stronger now. He has been off any tx since Aug. 2023 and his last PSA, was the same as 6 mos. prior, which was and is .014. Pre any Tx, PSA was 10.46
I hope this info helps you. Obviously, he did not have to go on chemo, nor was it recommended by his Radiation Oncologist.
