[A case of hormone/docetaxel-refractory prostate cancer in which PSA level decreased after docetaxel+zoledronic acid treatment].

The patient was a 63-year-old man who had a recurrence and bone metastasis of prostate cancer after total prostatectomy. He was diagnosed with prostate cancer refractory to hormones. Subsequently, the PSA level decreased after docetaxel therapy, but then gradually increased. Thus, he was diagnosed with bone metastasis of prostate cancer refractory to therapy with hormones or docetaxel. The PSA level decreased after the start of therapy with docetaxel+ zoledronic acid. Zoledronic acid seems to be effective not only for the prevention but also for the treatment of skeletal related events(SRE)in patients with prostate cancer with bone metastases.
