Hi Terry,
We're quite closely in step.
18 weeks on Zoladex has brought my PSA down from 47.21 to 0.15.
The preceding 6 months on wrong dose of bicalutamide only brought it down from 57.82 to 47.21.
I start my radiotherapy on Monday. However, as it's also treating nodes around the rectum (as a precaution, due to high PSA at diagnosis), SpaceOAR is no use for that.
After the radiotherapy finishes, I will be having high dose rate brachytherapy (HDR) and the SpaceOAR, if I have it done, is for that. Since the HDR is only a 33% boost over the radiotherapy, and my bowel is going to get hit by the radiotherapy regardless, it's not obvious to me it will give me much benefit. There's also the downside that it increases the risk of pushing micromets away from the prostate during the brachytherapy, which would cause eventual recurrence. Weighing these up against reduction in bowel disorders later is not an obvious win, hence having a conversation about the pros and cons.
