Intraoperative Radiation Therapy

Dr. GieldaNew option for early-stage breast cancer

A breast cancer diagnosis can be stressful and emotional. However, if caught early, you may have the option of avoiding weeks of radiation treatment.

Lakeland physicians are now using the ZEISS INTRABEAM® intraoperative therapy system to deliver a  targeted single-dose of radiation to the site of the tumor, after a Lumpectomy. 

Traditional external high-beam radiation requires patients undergo daily radiation to the whole breast, for a five or six week period.

The new therapy, also known as IORT, minimizes radiation exposure to healthy tissue and organs. It has also proven less costly, with limited side effects. Results have been so promising, Lakeland was asked to participate in the international TARGIT-B trial focused on the treatment.

It is important you have the advice and support of your breast care team before making an informed decision. Talk to your physician to see if IORT is right for you.  

Mammograms are key to early detection. Lakeland offers three convenient locations to serve you. Click here to schedule your appointment.

IORT Frequently Asked Questions

How effective is INTRABEAM IORT?
In 1998, a group of international researchers began investigating this method of radiotherapy delivery for breast cancer. The primary study tested the effectiveness of an intraoperative dose of radiation delivered using the INTRABEAM System compared with up to six weeks of conventional external beam radiation treatment (EBRT) for early stage breast cancer. The results of the trial were first presented in 2010 and show the overall number of cancer recurrences for both the EBRT and IORT patients were very similar. Ask your physician about the significant results from the trial named TARGIT-A, including complications.

How is INTRABEAM radiotherapy administered?
INTRABEAM IORT is delivered during breast-conserving surgery in the operating room while the patient is still asleep. Radiation is typically delivered for 20 to 30 minutes The treatment is delivered inside the lumpectomy cavity which minimizes radiation exposure to healthy tissue and organs.

Is IORT right for me?
For many women, INTRABEAM IORT is a viable treatment option. The physicians coordinating your breast conservation therapy will determine whether INTRABEAM radiotherapy is an appropriate treatment for your type of cancer.

What if I have been prescribed whole-breast radiation?
Some women undergoing conventional radiation treatment may have the choice of receiving INTRABEAM radiotherapy as a boost dose during cancer surgery, before the start of external radiation. This initial boost dose of radiation can be used in conjunction with standard course of external breast radiation.

Catching Cancer Early - Kellie Tyler

Cancer didn’t run in her family and for the last 17 years her mammograms came back clear. So at age 57, when a 1.3 centimeter mass appeared in her right breast, Baroda resident, Kellie Tyler, was shocked.

“When the biopsy came back as cancerous, I immediately started crying–I was very scared,” said Kellie. “My primary care provider was very encouraging and let me know that the cancer was only at Stage 1 which was the best-case scenario. She immediately got the ball rolling and referred me to the [Corewell Health] Marie Yeager Cancer Center.”

Kellie’s fears continued to lessen after meeting with nurse navigator, Shelley Wilkinson, RN, CBCN, who answered many questions. Shelley also informed Kellie that, because her breast cancer was at Stage 1, she was a candidate for a newer treatment, intraoperative radiation therapy (IORT). IORT delivers radiation at the time of surgery, following tumor removal. For many patients this eliminates the need for an additional six weeks of radiation.

“My care team remained so positive throughout the entire experience,” said Kellie. “They were extremely confident in the technology available here and that made me feel very safe.”

A few weeks following her initial diagnosis a general surgeon performed lumpectomy surgery to remove the cancerous cells. While still under anesthesia, radiation oncologist, Benjamin Gielda, MD, delivered a dose of radiation directly to the tumor bed.

“Of course, I was a little sore after the surgery but overall, everything healed really well,” said Kellie. “I’m so thankful I could be treated close to home and didn’t have to drive a long distance back and forth to appointments every day.”

Although the surgery had removed the cancerous cells and Kellie was now “cancer free,” a follow up blood test confirmed that her specific type of breast cancer was estrogen-fed. This put her at a higher likelihood for the cancer to return. As a precaution her oncologist recommended Kellie undergo four additional chemotherapy treatments.

“No one wants to go through chemo and I was very hesitant at first,” said Kellie. “But I trusted my care team and knew they had my best interests in mind. During my chemo treatments the staff at the Marie Yeager Cancer Center were amazing. They got me everything I needed right away and tried to make me as comfortable as possible.”

As she neared her last chemotherapy treatment, Kellie reflected back on the importance of early detection.

“Getting a regular mammogram is so important–it truly does save lives,” she said. “My cancer was so small that I likely would have never known it was there without a mammogram and the tumor would have just continued to grow.”

Kellie is also proud to say that, since her diagnosis, both her sisters and two women she works with have scheduled their mammogram appointments.
