Genitourinary Radiation Oncology

The Genitourinary Radiation Oncology program, directed by Yi An, MD, is comprised of a team of experts who deliver nationally-recognized and evidence-based radiotherapy, including cutting edge radiotherapy including ultrasound guided transperineal prostate brachytherapy and Image Guided – Intensity Modulated Radiation Therapy (IG-IMRT).

There have been major changes in the way radiotherapy is delivered for prostate cancer. Foremost among these changes is the development of Intensity Modulated Radiation Therapy (IMRT), which allows the precise shaping of radiation around the prostate, helping to avoid the surrounding critical areas such as the rectum and bladder. The Yale Prostate IMRT Program, originally developed by Richard E. Peschel MD, PhD, has become one of the most respected prostate radiotherapy programs in the country. The first to offer IMRT in 1998, the physicians of Smilow Cancer Hospital have the longest experience in Connecticut using IMRT. Since then, Yale has accumulated a vast experience with the IMRT and we have continued to enhance the techniques to deliver IMRT, which has led to extremely minimal complication rates of 1%. The resulting successes with IMRT technology at Yale have been published extensively, and our radiotherapy techniques have been clinically proven to lower side effects and improve radiation outcomes for men with prostate cancer. We are able to precisely account for daily set up error and patient positioning with daily 3-D imaging and reconstruction of the prostate and surrounding tissues using cone-beam technology. Development of the prostate cancer IMRT database at Yale has been supported by the Anna Fuller Foundation, and has been the source of multiple peer reviewed articles in the foremost medical journals. Using our experience with over 700 patients treated with IMRT, we are developing new guidelines and insights in the use of radiation for prostate cancer.

Patients who are cared for through the Urologic Oncology Program and need radiation therapy as a component of their prescribed treatment can feel confident that they are receiving the highest quality care from our experienced team of radiation oncologists. Together, with our proven and well-published experience in the physics of IMRT, our experience with prostate brachytherapy, and the research into the estimation of prostate cancer risk, Smilow Cancer Hospital is a true leader in prostate radiotherapy.
