After 5 Shots of Hormone treatment with Zoladex and casodex + Zometa, unfortunately my dad's PSA showed a sudden unpleasant rise, from 5 ng/ml to 46.9 ng/ml....

has anyone experienced a resistance so soon, i mean drs said that this should last at least for a couple of years for the body to become resistant to hormone?
