My Dad is in a lot of pain, mostly back pain, from prostate cancer that has now spread to his bones. He started Zytiga 5 days ago. He has trouble moving around and getting comfortable. My question I guess is, Is there a chance that Zytiga will help at this point?
Back pain, after 5 years of Zynga may indicate recurrence of disease. Hence I suggest get PSA levels and bone scan to document any progression of disease. Then he can be transferred on second line hormonal therapy or chemotherapy if he tolerates.
