Is he still on bicalutimide Annie or have they moved him onto an injection version (Zoladex or Prostap, for example)? That may make a significant difference.
The proper name for HT holidays is intermittent HT or IHT, if you want to search here for old posts / threads on it. Generally speaking there are conditions that the oncologist will want to see met, such as
- very low, stable PSA for a sustained period (often 2 years)
- no symptoms of active cancer
- an oncologist & a patient who both have some appetite for risk (some oncos refuse to even consider IHT no matter how well the patient is doing)
I have never seen IHT offered to a man on bical on here - but it is rare for someone with incurable PCa to only be on bical anyway. I suspect the reason IHT is more suited to injected HT is that it takes much longer to leave the body & for testosterone to start being produced and so the PSA takes much longer to start rising. With bical, the testosterone is there in his body so as soon as the tablets are stopped, the PSA may start rising.
