Hi my name is Jim.I was diagnosed with prostate cancer and some lymph involvement In September 2018. My psa was 1340. My urologist put me on daily Casodex 50mg for two weeks before starting Lupron. I had my first Lupron injection on October 24, 2018. The first time I had my psa checked after starting this regimen was on December 20, 2018. My MO called me on Christmas Eve to deliver the news. My psa was down to 2.4 in such a short time. I will be seeing my MO on January 18, 2019. On my first visit with my MO, he suggested Zytiga instead of Casodex. In light of this drastic change in psa in less than 2 months on Casodex, my question to you all is should I stay on Casodex or switch to Zytiga as my MO suggested?
