(Washington, D.C.) When Melvin Denwiddie, 73 was diagnosed with prostate cancer in late 2016 his physicians first told him the “watch and wait” strategy would be sufficient. But in 2017 further testing showed that his cancer had become more aggressive and it was time to get treated.
“My prostate cancer was potentially fatal if I didn’t start treatment,” says Denwiddie. “My choices were surgery to remove the prostate, traditional radiation or proton radiation,” says the great-grandfather of three. “I did my research and I wanted proton therapy. I found that proton therapy would be the most accurate; it would follow the shape of my tumor and would penetrate only the tumor and not any of the tissue outside of the tumor. That was very important to me.”
That’s when he found proton therapy at MedStar Georgetown University Hospital and his radiation oncologist, Jonathan Lischalk, MD.
“It’s important to sit down with patients and discuss their treatment options,” says Dr. Lischalk. “For localized prostate cancer, a variety of treatment options exist including surgery and radiation therapy. Even within radiation therapy, many options exist including proton therapy, x-ray-based therapy, and brachytherapy. Helping a patient understand his treatment options, the related side effects, and the clinical outcomes is extremely important.”
The proton therapy system at MedStar Georgetown is the first and only in the Washington, D.C. metropolitan area and is the first in the world to offer proton therapy with HYPERSCAN™ technology. HYPERSCAN produces beams that are sharper than other proton systems and treats patients faster.
Denwiddie received 43 proton treatments over the course of July through September 2018.
“From my standpoint, proton therapy is a very good treatment process. It was not invasive, it wasn’t painful and I experienced very few side effects,” says Denwiddie. “Aside from my bladder becoming overactive, it was a pretty easy treatment from beginning to end. And any side effects I had are getting better.”
With proton therapy complete, Denwiddie continues with hormone treatments for his prostate cancer under the care of his urology team at MedStar Georgetown.
“Proton therapy is proving to be an excellent option for prostate cancer treatment,” say Ryan Hankins, MD, a urologist at MedStar Georgetown University Hospital. “From a urology standpoint, I am able to use a small needle through the skin to place the needed fiducial markers and gel spacer to help improve patient outcomes and make proton therapy more precise. This is done with no incisions on the skin. Dr. Lischalk and I also coordinate patient visits to help make the patient's visit to MedStar Georgetown as seamless as possible.”
Denwiddie is a retired accountant for NASA but continues to prepare tax returns and represent clients before the Internal Revenue Service. “It’s a labor of love I’ve been practicing since 1972. It’s such a pleasure to know that I can continue to help people when they need it in this way.”
With his wife of more than 50 years newly retired and his prostate cancer treated, Denwiddie looks to the future with optimism and excitement.
“I feel confident that this prostate cancer is a thing of the past. The rest of my life, I’m looking forward to enjoying the freedom and flexibility to move around and travel with my wife. That includes visiting family and places I haven’t had the opportunity to see yet. I’m very excited about my future.”
