The bicalutimide is given before the HT implants etc to, I understand, prevent any flare when HT started, a normal process although everything not actually normal.
I started as G8 T3b slight sprrad to seminals. Upped to G9 after I had bit of prostate cut away (TURP) to aid urine flow. My treatment plan was 3yrs HT (Zoladex implant every 12 wks) and 32 sessions of RT. I had abiraterone,enzalutimide,prednisolone included on trial).
I actually didnt start RT until 12months after HT started, generally its around 6 months which allows the HT to have an effect. The delay was due to personal reasons, marriage etc, oncologist perfectly happy with that as HT doing its job. This highlighted the, in normal circumstances, that once treatment started theres no rush, providing HT working, once I got this in my head it was easier.
I did get probably all side effects re HT - fatigue, sleep issues, weight gain, muscle/bone aches/weakness, depression, hot flushes, total lack of libido etc whilst trying to stay a bit active. All basically expected and didnt really worry me as they'd go after treatment. I sought help from gp with the depression and acupuncture helped with hot flushes. Things returned to 'normal' a while after treatmet stopped.
RT wasnt too bad really, think it added to fatigue and did have a bit of bladder issues, frequency and bowel issues leadi g to a coup!e of accidents when out, embarrassing but never mind. Immodium did help when planning on being out a while. Bowels returned to normal.
My treatment started Oct 2015 last HT implant summer 2018. Something like 12-18 months after HT finished they will use PSA reading as the Nadir and use that as the benchmark for any changes.
My Nadir was 0.5 and aprart from one that was 0.55 every one has been below 0.5, my latest last week was 0.33.
So HT/RT has worked for me and ive been fortunate up to now anyway.
Hopefully you'll be able to settle down once into the treatment regime and realise everything being done, easier said than done obviously.
