About the Provider

Radiation Oncologist Sean Collins, MD, PhD, is director of the CyberKnife Prostate Program at MedStar Georgetown University Hospital and associate professor of Radiation Medicine at Georgetown University School of Medicine. Dr. Collins joined Georgetown in 2006 after completing his residency in radiation oncology at MedStar Georgetown and the Lombardi Comprehensive Cancer Center and, previously, a surgical internship at the Hospital. In addition to his medical degree, he also holds a doctorate in Biological Chemistry, both from the University of Michigan's Medical Scientist Training Program.

The major focus of Dr. Collins' clinical work is the development of prostate cancer treatment protocols using stereotactic body radiation therapy (SBRT). Patients receiving conventionally fractionated radiation therapy are treated daily for approximately 8 to 9 weeks; based on logistics and life responsibilities, such prolonged treatment courses present unnecessary hardship for patients and their family.  To date, Dr. Collins has enrolled more than 500 patients on investigator-initiated, IRB-approved clinical protocols exploring the role of SBRT in prostate cancer treatment.  His work has appeared in the American Journal of Clinical Oncology, Radiotherapy and Oncology, International Journal of Radiation Oncology Biology Physics, Cancer Journal and many other scientific publications. He also serves as a reviewer or editorial board member for numerous others, including the New England Journal of Medicine.

Philosophy of Care
"We work as a team to make sure that every patient receives the highest quality, most effective treatment available today. That's especially true for prostate cancer patients, where there are so many options. For us, treating prostate cancer is not only about curing the disease, but assuring each patient's long term quality of life. Toward that end, I establish open communications with my patients, for their ease of access and peace of mind from diagnosis through recovery."
