Prostate cancer is among the most common types of cancer diagnosed each year in the United States. Treatment for prostate cancer may include surgery, radiation therapy, hormone therapy, chemotherapy, or a combination of medical treatments. The treatment plan will depend on the size of the tumor, where it is located, if cancer has spread outside of the prostate, and other factors. In many cases, radiation therapy can help to fight prostate cancer.

At Johns Hopkins, a "top-ranked international team of doctors from multiple disciplines spanning surgery, oncology, and radiation oncology, all work together with one goal: to provide top quality and evidence-based treatment for our patients," explains Phuoc Tran, MD, PhD who specializes in radiation treatment for prostate cancer and other genitourinary malignancies.

"That single-minded dedication extends to the radiation oncology team that works with prostate cancer patients," he says. "Our nurses, physicists, dosimetrists and radiation therapists are all experienced in working with prostate cancer and understanding the technology and treatments."

Treating prostate cancer

An experienced radiation oncology team at Johns Hopkins specializes in the treatment of prostate cancer. As part of a larger multidisciplinary oncology team that works together to diagnose and treat prostate cancer, our team of radiation oncology specialists, including physicians, medical physicists, dosimetrists, nurses, and therapists, creates an individualized radiation therapy plan developed for the patient's specific needs.

Prostate cancer is commonly treated with:

External beam radiation, which includes 3D conformal radiation therapy, intensity-modulated radiation therapy (IMRT), and image-guided radiation therapy (IGRT).

TomoTherapy® and volumetric modulated arc therapy (VMAT), which are also types of external beam radiation, are often used to treat prostate cancer as well. It delivers small beamlets of radiation from every point on a spiral, allowing for targeted, high-dose treatments. Additionally, the tomotherapy machine creates a computed tomography (CT) image just prior to radiation treatment, providing a three-dimensional image of a patient's anatomy so that the size, shape, and intensity of the radiation beam can be adjusted to the precise location of the patient's tumor.

Brachytherapy: At Johns Hopkins, prostate seed implants are used to treat low- to intermediate-risk cancers. A multi-disciplinary team of doctors is available to work with each patient to determine the best course of treatment for that patient. Prostate seed implants offers these benefits:

  • Reduced irradiation to surrounding tissues, resulting in less damage
  • Shorter treatment time than standard radiation

Through our clinical research, we offer our patients the most effective and safest therapies available, in addition to clinical trials that patients can choose to participate in. Watch a webinar about the latest advances in prostate cancer radiation therapy.

The safety and well being of our patients and their families are always the primary concern of every member of the radiation oncology team. We have developed a comprehensive safety program that is unique to Johns Hopkins. As an international leader in radiation safety, our standards for safety serve as an example for other academic and community-based radiation practices. Our safety program not only complies with state and national protocols, it goes well beyond those protocols by integrating innovative safety techniques developed by experts on our staff.
