you could try and substitute Zytiga and use Ketoconazole (both require added Prednisone or cortisoid), both target enzyme CYP17.....don't know if there is definitive evidence that Zytiga is better (should be based on price). Zytiga around $4,350-5,500 a month (USA), Ketoconazole (from Canada in USA $$$) as low as $35 (30 pills). See
www.northdrugstore.com (Rx accepted from USA so probably acceptable from China, you need to pay shipping, in USA shipping is only $10). They sell zometa (for bone density) and the prices are cheaper in Canada usually by 50-80% it seems. Not sure if they have Xgeva, but they sell alot of PCa drugs. Good luck in shopping and also see
www.hrpca.org (proven therapies)
Zytiga canada link above $5,423 120 tablets
Cheap PCa drugs for cash strapped people: DES (no patents, found as low as $130 per year 1-mg)
Generic casodex, eulexin (flutamide), Ketoconazole, estradiol patches or gels, emcyt and others.
