Individualized Radiation Therapy from Expert Physicians

Our Radiation Medicine physicians are leaders in the use of targeted radiation therapy, with access to clinical trials and cutting-edge technology.  

As MedStar Georgetown University Hospital physicians, we are an integral part of the Lombardi Comprehensive Cancer Center, the only National Cancer Institute (NCI) designated comprehensive cancer center in the Washington, D.C., area. We train tomorrow’s leading physicians in Radiation Medicine.

Above all else, we care. We take time to explain your options and develop a treatment plan that will aggressively treat your condition and protect your quality of life. Every patient and every cancer diagnosis is different, so we think every treatment should be tailored as well. What sets our team apart:

Top Physicians Pioneering Effective Treatment

Our physicians are committed to further advancing cancer treatment through basic and translational research, innovative clinical trials and a commitment to caring for the emotional and physical challenges that come with a cancer diagnosis.

Multidisciplinary Evaluation and Treatment

Specialty teams collaborate across disciplines to evaluate and develop treatment plans that consider every angle, marrying your unique needs to the latest advances in medicine. You can meet us all in one day. This approach is more convenient—and research shows it leads to better outcomes.

Specialized Clinical Expertise:

Each physician on our Radiation Medicine team has spent their career treating specific conditions with the most effective radiation medicine available. Your physician’s intimate knowledge of the affected area and mastery of latest technologies helps them target cancer cells and avoid treating healthy tissue. That greatly limits potential side and long-term effects.

Sophisticated Technology:

We offer sophisticated treatments, backed and driven by research and tailored to your needs. The only hospital in the region to offer CyberKnife Radiosurgery and Proton Beam Therapy, our targeted radiation therapy treatment options deliver high dose radiation with extreme accuracy, sparing normal tissue and helping to shorten treatment times, maximize effectiveness and improve patient comfort and outcomes.

Dave's Story

"Prostate Cancer is Not the End of Your Life"

 When David Viglione’s elevated PSA could no longer be ignored, a biopsy confirmed his prostate cancer diagnosis.

His urologist talked about surgery, but David was looking for a therapy to match his active life.  No downtime. Few side effects.

“Then my wife convinced me to go to MedStar Georgetown and ask about Cyberknife treatment,” David says.

CyberKnife is a painless radiation therapy procedure performed without anesthesia—and no hospitalization. With more than 1,100 procedures performed, MedStar Georgetown is one of the nation’s most experienced CyberKnife centers.

“CyberKnife is a very sophisticated computer technology that allows us to directly target the prostate, while limiting harm to surrounding healthy tissue,” explains Dr. Collins, radiation oncologist.

“With CyberKnife, patients receive five, 40-minute treatments of high dose radiation during a two week period, compared to standard low dose radiation therapy that requires treatment five-days-a-week for up to nine weeks,” he adds.

David had an intermediate risk prostate cancer and was a good candidate for the procedure as he was very active and wanted a way to treat his cancer that would not disrupt his busy life.

Prior to the procedure, the MedStar Georgetown team implanted gold markers the size of a grain into David’s prostate. The markers guide the system’s robotic arm and target its high energy beams of radiation to the tumor with precision accuracy.

“The procedure had no impact on my daily routine and no side effects,” says David.

Now six years later, David calls himself the “poster child” for CyberKnife. “I’m proof that prostate cancer is not the end of your life. MedStar Georgetown gave me options. They put my needs and concerns first!”
