IGRT Treatment in Staten Island, NY
Image-guided radiotherapy (IGRT) is an innovative and precise way to treat cancer. Rather than using imaging tools before and after treatment like traditional radiation therapy, IGRT uses them throughout treatment. This allows oncologists to target tumors that may have changed during treatment, improving outcomes.
Richmond University Medical Center in Staten Island, New York, provides IGRT to patients at our state-of-the-art Center for Cancer Care. Our center is staffed by an experienced staff of oncologists, radiologists and medical professionals who use the latest equipment and technologies, like IGRT. They perform thorough evaluations to ensure that IGRT is right for the patient and to guide a treatment plan for best results with reduced risk. Learn more about IGRT, how it works, and its benefits.
What Is Image Guided Radiotherapy?
Image-guided radiotherapy (IGRT) is a form of cancer treatment that uses advanced imaging technology. In the past, oncologists would determine the stage of a patient’s cancer and take images before beginning treatment, using this information to plan an entire course of treatment. While staging and imaging still follow diagnosis, imaging tools are now used throughout the treatment process. With ongoing, up-to-date information from imaging tests, oncology teams can provide more accurate and effective cancer treatment.
Cancerous tumors can alter in shape and size during a course of radiation. With imaging guidance, oncologists can adjust treatment in response to these changes in the tumor. They will use a variety of imaging technologies, including:
- Ultrasounds
- X-rays
- Magnetic resonance imaging (MRI)
- Computer tomography (CT) scans
How IGRT Is Used to Treat Cancer
IGRT is now the standard of care in radiation therapy. With IGRT, oncologists can use imaging results to better target tumors that may have changed or moved during treatment. This minimizes the damage to surrounding healthy tissue and can improve treatment outcomes.
Before beginning cancer treatment, a patient will typically have a series of tests to inform their treatment plan. If radiation therapy is recommended, they will have a schedule of appointments over several weeks or months. Before each radiation session, additional imaging tests will be completed. These real-time scans are used to help radiation oncologists decide if a treatment plan needs to be adjusted.
The benefits of IGRT include:
- Precision: Because IGRT helps pinpoint a tumor, providers can use higher doses of radiation to kill cancer cells.
- Fewer side effects: This precision also means that patients may experience fewer radiation side effects.
- Protecting healthy cells: IGRT targets cancer more effectively while sparing healthy tissue around the tumor.
IGRT is used in all kinds of cancer treatments. However, it is particularly useful in treating tumors that are located near sensitive organs or are likely to move during treatment.
What to Expect During Treatment
During a radiation therapy session, a patient is positioned on a treatment table. A medical provider will take scans to ensure the patient is properly positioned. They may use MRIs, CT scans, or other types of imaging to verify the treatment area. They may also use ultrasound guidance to place tiny metal implants, known as fiducial markers, which help to pinpoint specific tumor locations.
Once the patient is ready for treatment, a provider will operate a machine that delivers precise doses of radiation. The radiation is not painful. The patient may hear buzzing or beeping noises as the radiation machine moves around. Each session is relatively short. Often patients have radiation therapy sessions five days per week over several weeks. At each session, the medical team will continually review imaging scans to adapt the patient’s treatment as needed.
Types of Cancer Treated with IGRT
Oncologists utilize IGRT to treat several different types of cancer, including:
Breast Cancer
Breast cancer can develop in one or both breasts. There are several types of breast cancer, including:
- Lobular carcinoma
- Ductal carcinoma
- Inflammatory breast cancer (IBC)
- Triple-negative breast cancer
- Paget’s disease of the breast
Using IGRT to treat breast cancer helps protect the heart and lungs by minimizing their radiation exposure.
Lung Cancer
The two main types of lung cancer are non-small cell lung cancer (NSCLC) and small cell lung cancer (SCLC). NSCLC is much more common, but smoking is a major risk factor for both types of lung cancer. Lung tumors can naturally move as a patient breathes in and out. IGRT is often used in lung cancer treatment because it helps pinpoint tumors that can move during or between treatments.
Prostate Cancer
Treating prostate cancer can be challenging because the prostate gland tends to shift. Because it is located near the rectum and the bladder, the prostate can be pushed in different directions if the bladder is full or the rectum has gas or stool. Before IGRT, radiation oncologists had to treat a larger perimeter around the prostate. Now, they can shrink those margins and deliver more targeted doses of radiation.
