Hi Marye
Sorry that you find yourself here, we all understand the worry and dark thoughts that you must be having, I think most of us will have/are having/have had them.
I am no expert but in the uk the current protocol for most men is early chemotherapy (once the cancer has spread and becomes incureable) which does what you are suggesting i.e. Bash it at the start. Then if PSA increases either enzaclutamide or abiraterone (not usually described as chemo). Along the way injections of zoladex/prostap every 3 months to deter the hormones. There is another drug, biclutamide that is sometimes prescribed although most men don't seem in it for long with advanced pc from what I can see.
I was told maybe only two years but that is nearly 3 years ago, I had early chemo (docetaxl), zoladex every three months , biclutamide (briefly) and then started abiraterone Jan 2016. Touch wood it's still doing its stuff , last PSA 0.11 so lowest ever. Side effects, plenty of niggly ones but nothing that has stopped my love or ability to enjoy life.
Though this perhaps sounds strange , my life has been more fulfilling, I have done more for others, had some amazing experiences, met people who I would never have met all because I have prostate cancer. Don't get me wrong, I wish I never had it but to date the prostate cancer cloud has had a silver lining as it was a wake up call to chase my dreams. I know I am a bit younger than many in this site so am potentially more able but I have run so many races in amazing countries that I would never have been to and also I am told have inspired many to not give up. A day one spends sad, no matter how understandable, is a wasted day that you won't get back so I try so hard every day to do something positive and most days , but not all, manage it.
Keep searching for a silver lining every day
