Hi Coldpillow,
The psa level isn't too high, although it isn't a real guide.
The trouble is that everyone is different so all you can say is that most people react in some way.
The treatment sounds normal from what I've read. If I was you I'd take everything offered. Hormones and Chemo. Chemo is supposed to improve the Hormone effect. Chemo on it's own isn't a fix with prostate cancer.
Some people don't get offered surgery because the tumour has gone outside the prostate or they're too heavy or health not good enough or due to age. It's quite an onerous operation as you slope head down.
Radiotherapy can treat a wider area so is probably better for your husband and most studies say outcomes are similar to surgery overall.
Having the Radiotherapy at the earliest date would be my thought hoping it was after 3 months of hormones and not 6. Although someone else might know more as I didn't have RT. I'd be wanting it done in case it changes.
If you are to come on here more it will be useful for you to fill out your profile as people do read it to make sure their replies are more relevant. There are so many different factors it's quite amazing.
All the best, Peter
