Treatment Philosophy
In addition to my focus on treating and caring for patients with prostate and bladder cancer, it is my responsibility as Chairman of the Department of Radiation Oncology at Fox Chase; an NCI designated National Comprehensive Cancer Center to promote the mission of the Center to prevail over cancer. Our department's expertise has always focused on developing and integrating sophisticated technology into successful treatment for our cancer patients and I remain committed to continuing and expanding this legacy. However, the successful treatment of a patient is not just based on the technology that is available. Being diagnosed with cancer and receiving treatment is one of the most difficult things that many people will ever face, and it is crucial that we as caregivers do not forget this. Caring for patients as one important part of a multidisciplinary team allows us in the Department of Radiation Oncology to provide the best possible care for our patients.

Daniel Haubrich
Daniel Haubrich
After Daniel Haubrich was diagnosed with prostate cancer in 2005, his urologist did not think he was a good candidate for surgery, and he offered Daniel little hope that he would make a full recovery. Daniel knew he needed a second opinion and scheduled an appointment at Fox Chase Cancer Center to see a more experienced surgeon. This time, he was recommended for surgery, and after both surgery and radiation in early 2006, he is now cancer free. "I am grateful to both Dr. Chen and Dr. Horwitz for their positive attitudes, their commitment to care, and for treating me with respect," he said. "My experience at Fox Chase was always positive."
Kevin Logan
Kevin Logan
In 2010, Kevin Logan noticed a lump on his neck which turned out to be squamous cell carcinoma on the base of his tongue. Upon the recommendation to seek treatment at Fox Chase Cancer, that's where Kevin and his wife, Devra, went even though it was a three-hour drive from their home in Maryland. Kevin underwent a successful treatment of surgery, chemotherapy, and radiation, and once he finished treatment, he returned to work full-time. "Many people who knew about my cancer often called to ask where I was treated, and I’m always telling them, 'Fox Chase is the place to go,' and I always will," he said.
Ed Horowitz
Ed Horowitz
When Ed Horowitz was diagnosed with prostate cancer in 2008, he had to make a decision whether to undergo radiation or surgery. After receiving one opinion from a surgeon at a large Philadelphia hospital, he decided to seek a second opinion from Dr. Eric Horwitz, chair of radiation oncology at Fox Chase Cancer Center. Ed liked Dr. Horowitz's warm demeanor and sense of humor and decided to be treated with IMRT (intensity modulated radiation therapy) combined with hormone injections, followed by radiation and hormone therapy. The treatment was successful. A few years later, his cancer returned, isolated to his shoulder this time. Ed started another course of chemotherapy in March 2016. "My cancer has not grown and has not spread since I completed chemotherapy," he said. "I always recommend Fox Chase to anyone considering treatment for prostate cancer. I consider myself fortunate to have gone there for treatment."
James Slade
James Slade
I was in my early 60s when my first PSA blood test detected slightly elevated levels, and I was advised to be retested 8 months later. When the levels increased 50% on the second test, my doctor in New Jersey performed a biopsy. The diagnosis was prostate cancer.
John Donahue
John Donahue
John Donahue was concerned about prostate cancer. From the time he had surgery for an enlarged prostate, John was always aware of his PSA (prostate-specific antigen) level (a protein produced by the cells of the prostate gland). Although his levels were within normal range, they were on an upward climb over a period of 3 to 4 years.
