Prostate Cancer Patient Does His Research and Chooses Proton Therapy to Treat His Aggressive Disease

Dr.-Lischalk-with-Denwiddie(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.”

Combined Technology improve Breast Reconstruction Outcomes in Breast Cancer Patients

dsc_1156“My surgeon told me he would decide during surgery whether or not I could undergo breast reconstruction immediately, but I’m so glad he decided to wait before proceeding with implants. It gave me a chance to heal, and the results of my reconstruction are just remarkable,” said Sarah Bessin, a 47-year-old breast cancer survivor.  

Bessin was diagnosed with breast cancer in July 2015. After she opted to begin breast reconstruction at the same time of her mastectomy in October 2015, Bessin reaped the benefits of undergoing breast reconstruction that combines two tissue-saving technologies to diagnose and avoid serious complications.

The unique combination of SPY Elite and Hyperbaric Oxygen Therapy at MedStar Georgetown saved Bessin’s breast tissue and improved her breast reconstruction outcome. To date, MedStar Georgetown University Hospital is the only center in the Greater Washington, D.C. region offering the combination of SPY Elite and hyperbaric oxygen therapy for patients with breast cancer.

“Everything that we do in plastic surgery involves blood flow. If blood flow is disrupted, skin above it can flake off and even die. This is the reason we need to be able to anticipate those problems intraoperatively so we can act quickly,” says Troy Pittman, MD, Bessin’s breast reconstruction surgeon.  

A New Valuable Player in the Operating Room

After a mastectomy, the plastic surgery team enters the operating room with a fluorescent imaging system, SPY Elite. SPY Elite has a long arm that connects to an infrared lamp device, which is used for scanning over a patient’s body. A special contrast is injected through the patient’s IV line, and a TV monitor shows the scans of breast tissue and blood vessels in real time. A breast reconstruction surgeon will move the SPY Elite lamp over different areas of the breast to detect the quality of blood flow in breast tissue before proceeding with the surgery. The system’s monitoring of the blood flow helps surgeons determine if the patient’s tissue is in a safe state to move forward with surgery and place an implant. If blood flow is limited, surgeons will add hyperbaric oxygen therapy after surgery to promote healing in the tissue.

 “SPY Elite lets me look at the blood supply of the breast tissue and the nipple in real time. This helps us diagnose a problem early on and initiate hyperbaric oxygen within 24 hours, if we need to,” says Dr. Pittman.

SPYing a Problem

During Bessin’s procedure, the SPY Elite imaging system informed Dr. Pittman’s team that there were worrisome vascular changes in her breast skin following the mastectomy. To avoid compromising the vascular health of the skin, Dr. Pittman decided on a different plan. The new breast reconstruction approach for Bessin meant waiting on the implants and placing tissue expanders, a type of deflated temporary implant, in the surgery site. This plan allows for healing time in the hyperbaric oxygen therapy chamber. dr-pittman-working-in-surgery

“Our goal is to get patients in for treatment as soon as possible. We are aggressively treating the patient to save their breast tissue and augment their healing,” said Kelly Johnson-Arbor, MD, medical director of Hyperbaric Medicine in the Department of Plastic Surgery. “Our dedicated team of physicians, nurses and technicians works to ensure that patients remain safe and comfortable during their treatment regimen.”

Healing Tissue within Days

Hyperbaric oxygen therapy exposes patients to pure oxygen in a pressurized space. Sending patients to the hyperbaric oxygen chamber treats the initial blood flow issue and can help the patient avoid future healing problems. Although treatment begins within 24 hours after surgery, patients do not have to stay at the hospital. Patients will only visit the hyperbaric oxygen therapy chamber once or twice a day for about an hour. 

Bessin’s tissue healed in only 13 hyperbaric oxygen therapy treatments. Her hyperbaric oxygen therapy schedule started with two visits to the hospital per day, which later decreased to one visit per day near the end of her treatment.  

“I bounced back quite quickly. I’m already working my normal schedule, and my energy level is back to normal,” said Bessin. “I’m so grateful to my doctors for providing this therapy!”

Treatment Affords Rest and Relaxation Time

Bessin said she spent most of her time relaxing in the hyperbaric oxygen therapy chamber, which is a large glass tube. In the chamber, patients are required to leave most items outside of the chamber to minimize any chance of creating a spark in the oxygen chamber.  Patients cannot wear makeup, lotion, nail polish or outside clothing, nor can they bring in cell phones, books or paper. A glass of water and a cotton gown are permitted inside the chamber. During treatment, a nurse or technician stays in the room the whole time to administer the hyperbaric oxygen therapy, answer questions or assist with movie selections.

“Georgetown has a great movie selection!” said Bessin.

Access for Every Breast Reconstruction Patient at MedStar Georgetown

Dr. Pittman has used SPY Elite with hyperbaric oxygen therapy at MedStar Georgetown for five years. For breast reconstruction, Dr. Pittman’s team uses SPY Elite on almost every patient, but particularly in those who want to begin breast reconstruction with an implant immediately after a mastectomy.

“SPY Elite and hyperbaric oxygen therapy allow us to aggressively treat patients safely and predictably,” said. Dr. Pittman. “This approach gives our patients the best chance for success.”
