    Dr. Richard Stock has dedicated his career to delivering the highest quality care to patients using the most advanced technology available, including intensity modulated radiation therapy (IMRT), Novalis shaped beam radiosurgery, real-time ultrasound guided prostate seed implants and Mammosite, all of which allows for meticulously targeting the tumor while achieving maximal sparing of normal tissues.

    Dr. Stock has served on the board of American College of Radiology Testing and the American Brachytherapy Society, where he is member at large, and as guest editor of a special Brachytherapy issue of Techniques in Urology. He has lectured and presented at dozens of meetings and symposiums across the country and internationally, including New York, San Francisco, Chicago, Philadelphia, Boston, Spain, Holland, France and Japan.
    Dr. Stock completed his internship at Beth Israel Medical Center and his specialty training at Memorial Sloan-Kettering Cancer Center.  He is listed in America's Top Doctors.

    Read the commentary by Richard G. Stock, MD, Simon J. Hall, MD, William K.Oh, MD, and David B. Samadi, MD, " Fighting Round Two: Recurrent Prostate Cancer" that appeared in the New York Times on June 8, 2010.


Dr. Stock's specific focus is prostate cancer and prostate brachytherapy.  He established a comprehensive prostate cancer database with a corresponding IRB approved protocol to track treatment outcomes following prostate cancer therapies.  This has enabled him to obtain important medical information on the growing field of low dose rate brachytherapy and prostate cancer. Dr. Stock's efforts over the past 16 years, which includes 145 peer reviewed and invited papers, and book chapters, have contributed much to our understanding of prostate brachytherapy.  He has helped set standards for dosing issues and implant quality. In addition, he has collaborated with other brachytherapy centers to publish multi-institutional series which have further enhanced our understanding of this treatment modality.  Working in collaboration with other researchers, Dr. Stock has studied the relationship between genetic mutations and radiation side effects in patients undergoing radiation for prostate cancer.  He is a co-investigator on a Department of Defense, American Cancer Society, and NIH RO1 grants to study this new and exciting area of research. In a recent publication in the International Journal of Radiation Oncology Biology Physics, Dr. Stock ranked among the top 4% of academic radiation oncologists in terms of the h-factor, a surrogate score for research productivity.

Industry Relationships

Physicians and scientists on the faculty of the Icahn School of Medicine at Mount Sinai often interact with pharmaceutical, device and biotechnology companies to improve patient care, develop new therapies and achieve scientific breakthroughs. In order to promote an ethical and transparent environment for conducting research, providing clinical care and teaching, Mount Sinai requires that salaried faculty inform the School of their relationships with such companies.

Dr. Stock did not report having any of the following types of financial relationships with industry during 2015 and/or 2016: consulting, scientific advisory board, industry-sponsored lectures, service on Board of Directors, participation on industry-sponsored committees, equity ownership valued at greater than 5% of a publicly traded company or any value in a privately held company. Please note that this information may differ from information posted on corporate sites due to timing or classification differences.

Mount Sinai's faculty policies relating to faculty collaboration with industry are posted on our website. Patients may wish to ask their physician about the activities they perform for companies.
