Radiation oncology treatment room

Radiation oncologists John Mastandrea, MD and Emily Kowalski, MD are shown in the Requard Radiation Center in the Cancer Center at UM Shore Regional Health.

Radiation therapy is a form of cancer treatment that shrinks tumors and kills cancer cells.

Used together with medical and/or surgical oncology, radiation therapy focuses high-energy beams on cancer cells to damage their DNA. Cancer cells with damaged DNA stop dividing and die.

Modern advanced technology makes radiation therapy quicker and safer than ever. Our technologies are delivered with pinpoint accuracy, avoiding damage to surrounding tissue and organs. Most treatments are done in an outpatient setting with some lasting just a few minutes so that you can get back to everyday life.

At the Requard Radiation Oncology Center in Easton, our team provides patients on the Eastern Shore with access to the latest therapies and technology in radiation therapy.

As a part of the Cancer Center at UM Shore Regional Health, we work with specialists from medical and surgical oncology, among others, to develop a unique treatment plan for each of our patients, knowing that no two cases are alike. Our radiation oncologists collaborate with other members within the department on each individual case to help patients put cancer behind them.

Therapies and Technology

At the Requard Radiation Oncology Center, our radiation oncologists use the best technology available for treating tumors right here on the Eastern Shore.

Our team of specialists, which includes radiation, medical and surgical oncologists, will discuss your case together and create a treatment plan to give you a chance for the best outcome. Your recommended options for treatment may include one or more of the following:

  • External beam radiation therapy is the most common type of radiation therapy used for cancer treatment. A machine is used to aim radiation beams from outside the body into the tumor. The machine we use is a Varian linear accelerator.
  • Three-dimensional treatment planning (3D-CRT) delivers radiation beams from different directions designed to match the shape of the tumor. This helps to reduce radiation damage to normal tissues and better kill the cancer by focusing the radiation dose on the tumor.
  • Intensity-modulated radiation therapy (IMRT) is like 3D-CRT, but It also changes the intensity of the beams to deliver a more precise dose of radiation to the tumor while further reducing the amount of radiation to healthy surrounding tissue.
  • High-dose-rate (HDR) brachytherapy (sometimes referred to as internal or intracavitary radiotherapy) involves placing radioactive sources in or next to the cancer.
  • Stereotactic radiosurgery (SRS) isn't really surgery, but a type of radiation treatment that treats inoperable cranial and spinal tumors with a very fine and ultra-precise radiation beam. These treatments usually are delivered in 1 to 5 sessions versus over the course of several weeks when compared to normal external beam radiation therapy.
  • Stereotactic body radiotherapy (SBRT) is the same technology as SRS except it is used to treat sites outside of the cranium and spine.
  • Image-guided radiation therapy (IGRT) x-rays are used to accurately align the patient prior to treatment based on each individual patient's internal anatomy.
  • On-site big bore CT scanner is used to determine the exact size, shape and location of the tumor and this information is used to create an individualized treatment plan.
  • Deep inspiratory breath hold (DIBH) with optical surface monitoring system (OSMS) for the treatment of thoracic tumors, breast cancer and lymphomas. This technology ensures the radiation beam is on only when patients are holding their breath, pulling the heart away from the tumor treatment field.

Patients at the Requard Radiation Oncology Center also have access to an even larger team of radiation oncology experts and state-of-the-art treatments available at the University of Maryland Marlene and Stewart Greenebaum Comprehensive Cancer Center (UMGCCC) and the Maryland Proton Treatment Center (MPTC). These include therapies not often found elsewhere, such as:

These additional tools help ensure that you can receive a treatment plan that's ideal for your situation. Should you require radiation treatment at either UMGCCC or MPTC in downtown Baltimore, you will receive free valet parking with our complimentary Concierge Program. One of our team members will also meet you at the front door to escort you to your first appointment.

Support During Cancer Treatment

We know that cancer care is more than just having access to advanced treatments. It can affect a person's life in more ways than one, and at the Cancer Center at UM Shore Regional Health, we give our patients access to a number of support systems, including diet and nutrition guidance, support groups, financial consultations and more.

Our dietician provides dietary education and treatment plans during radiation and ongoing monitoring to help patients manage side effects and recover optimally after radiation. Our social worker connects our patients with resources that help to minimize the ancillary challenges that arise as our patients navigate cancer treatments. At the Requard Radiation Oncology Center our doctors and nurses also have an excellent relationship with UMMS Shore Health Palliative care and local private hospice providers.
