    William K. Oh, M.D. is the Chief of the Division of Hematology and Medical Oncology; Professor of Medicine and Urology; and Ezra M. Greenspan, MD Professor in Clinical Cancer Therapeutics at the Mount Sinai School of Medicine and Associate Director for Clinical Research, The Tisch Cancer Institute.

    Clinical Interests: Management of genitourinary malignancies, including prostate, renal, bladder, adrenocortical and testicular cancers.  
    Research Interests: Dr. Oh's research interests include exploring the role of chemotherapy in both castration-resistant prostate cancer (CRPC) and localized high-risk prostate cancer.  In collaboration with laboratory-based colleagues, we are assessing changes in the expression of tissue and serum biomarkers due to chemotherapy.  Another area of interest relates to the role of secondary hormone therapies in the treatment of advanced prostate cancer.  

    Another major research area has been the development and management of a prospective clinical database linked to blood and tissue banks for prostate cancer patients. Dr. Oh's recent research efforts exploring this database have included characterization of the efficacy of various therapies in advanced prostate cancer (e.g., nilutamide, ketoconazole, vinorelbine, docetaxel, mitoxantrone), assessment of PSA doubling time as a prognostic and predictive factor, efficacy of hormonal therapy, assessment of testosterone as a marker for cancer outcome, prediction of relapse based on nutritional factors at diagnosis and autoantibody signatures, and assessment of pharmacogenomic patterns predicting Gleason score.
