My Husband Has Stage 4 Prostate Cancer That Has Spread

My husband has stage 4 prostate cancer that has spread to the bones and the liver. Diagnosed in March of 2015 and he will be 54 on the 25th of October. Has been on Taxotere, Xtandi and Zytiga and psa keeps raising (185 as of now I think). Starting Jevtana this coming Wednesday. Gets a Lupron shot and Zometa. Looking for some hope, I guess. We have Health Alliance PPO and self-employed. Thank you in advance. Deana
