My husband (who is 45 years old) was diagnosed in Oct of 06'. Gleason 8 (4+4), Stage D. He is on Casodex and Eligard, and his PSA level is now 0.4. His doctors claim he can stay on these meds for many years.
HIs cancer has already spread to his spine, hip, left femur, and lymph nodes in his abdomen.
