Carl Zeiss Meditec's INTRABEAM Targeted Intraoperative Radiotherapy System Demonstrates that Single-dose Radiation is Equivalent to Prolonged Courses of Post-operative Radiation for Early Breast Cancer Treatment

TARGIT-A Results for the Largest Randomized Clinical Trial Conducted in Intraoperative Radiotherapy to be Reported at ASCO 2010

CHICAGO, IL--(HSMN NewsFeed) - Carl Zeiss Meditec announced that outcomes for the TARGIT-A multicenter clinical trial, which used the INTRABEAM® System to deliver a single dose of intraoperative radiotherapy (IORT) to the breast following breast conserving surgery, will be presented today at the American Society of Clinical Oncology (ASCO) meeting. The TARGIT-A study results, with up to 10 years maximum follow-up, have also been published as a fast-tracked peer-reviewed paper in The Lancet, now available at

Professor Michael Baum, MD, co-principal investigator of the TARGIT-A multicenter clinical trial, will present the late-breaking abstract (ASCO abstract #LBA517) titled, "Safety and efficacy of targeted intraoperative radiotherapy (TARGIT) for early breast cancer: First report of a randomized controlled trial at 10 years maximum follow-up," today at 2 p.m. at the ASCO Meeting at McCormick Place in Chicago, IL.

"I am pleased to report these positive outcomes on behalf of the TARGIT group for what we believe is one of the most important studies to be conducted in the field of breast cancer to date," said Prof. Baum, who pioneered the TARGIT approach using the INTRABEAM® system along with Jayant S. Vaidya, MD, PhD and Jeffrey Tobias MD, PhD. "Now that the TARGIT-A trial has demonstrated that single-dose intraoperative radiation treatment using INTRABEAM is equivalent in efficacy and safety to traditional radiotherapy in the longest-running clinical trial of its kind, TARGIT treatment has the potential to become the new standard of care in breast cancer."

The INTRABEAM® system features a unique radiation delivery and dose distribution profile that allows targeted radiation to penetrate the tumor bed after breast conserving surgery while reducing exposure to the chest cavity and underlying organs. It is the only single-dose partial breast irradiation technology that has been studied in a randomized multicenter clinical trial. In the TARGIT-A multicenter clinical trial, which has achieved up to 10 year follow-up data, preliminary study results demonstrate the equivalency of single-dose targeted IORT in comparison to external beam radiation (EBRT) based on local recurrence.

"This is a critical breakthrough for women and a major advance in our ability to tailor treatments for women, depending on the biology of their tumors," said Laura Esserman, MD, MBA, Director, Carol Franc Buck Breast Care Center and Professor of Surgery and Radiology, University of California, San Francisco. "It is also an important step forward for patient-centered care and addresses the challenges and difficulty for women to return for daily radiation treatments over many weeks. It is wonderful to have the opportunity to offer women an appropriately tailored therapy that reduces their risk and diminishes the burden of cancer care."

The TARGIT-A trial is a randomized controlled study launched in 2000 in which 28 centers from 9 countries throughout Europe, North America and Australia participated with an accrual of 2,232 patients. The study was designed to assess the equivalence of targeted intraoperative radiotherapy with a single-dose using INTRABEAM® against standard three-to-six week external beam radiotherapy using linear accelerator technology after breast conserving surgery in women 45 years and over with invasive ductal carcinoma.

There are several potential benefits to INTRABEAM® single-dose TARGIT treatment, including:
  • A significant reduction in radiation treatment time for the patient.
  • Improved access to radiation therapy for patients in rural areas and developing countries.
  • Less toxicity related to external beam radiotherapy.
  • Minimized exposure to healthy tissues and organs.
  • No treatment delay for patients who must also undergo chemotherapy as part of their breast cancer treatment.
  • Cost savings to hospitals and breast cancer treatment centers.
"These impressive study results mean that we have passed a key milestone in breast cancer treatment with INTRABEAM," said Dr. Ludwin Monz, President and CEO of Carl Zeiss Meditec AG. "INTRABEAM has the potential to become the new global standard treatment for breast cancer. We will continue to invest in this field, to enable as many patients as possible to receive INTRABEAM treatment."

About the TARGIT-A trial

Since 1996, the international TARGIT research group has been researching a new method of delivering radiotherapy for breast cancer in which the treatment can be reduced to a single fraction at the time of surgery. The INTRABEAM® radiotherapy system from Carl Zeiss is the radiotherapy platform used in the TARGIT-A trial since its inception and it is the cornerstone technology for this new approach to radiation therapy. The TARGIT clinical trial evaluates whether a single dose of radiation can reduce the risk of recurrence in early breast cancer as effectively as the traditional, three to six week external beam radiation treatment. The TARGIT-A clinical trial randomized half of the study group to receive conventional external beam radiotherapy while the other half was randomized into the single treatment radiation intra-operatively with the INTRABEAM radiotherapy system. The results of the study will be presented for the first time during the 2010 American Society of Clinical Oncology Annual Meeting (ASCO) in Chicago from June 4-8.

About The INTRABEAM® System

INTRABEAM®, Carl Zeiss Meditec's ground breaking radiotherapy system, offers the least disruptive treatment method available to patients diagnosed with early stage breast cancer. The radiation dose of INTRABEAM® is administered to the tumor bed in the operating room immediately following the surgical excision of the tumor. The system utilizes a miniature X-ray source, a highly flexible support stand and a full range of radiation applicator options. INTRABEAM has the advantage of delivering a precise radiation-dose to the tumor site at the time of surgery minimizing geographical miss and the associated side effects with external beam radiation. Afterwards, the applicator and miniature X-ray source are removed, the surgical site is closed, and the procedure is complete. In 1999, INTRABEAM® received both FDA clearance and CE mark to deliver a prescribed dose of radiation to the treatment margin or tumor bed during intracavity or intraoperative radiotherapy treatments. The device is also cleared for use in most countries around the world. Please visit for more information.

US FDA-Cleared Indications for use:

The INTRABEAM® Spherical Applicators are indicated for use with the INTRABEAM® System to deliver a prescribed dose of radiation to the treatment margin or tumor bed during intracavity or intraoperative radiotherapy treatments. The INTRABEAM® Balloon Applicator together with the INTRABEAM® System is intended to deliver intracavitary or interstitial radiation to the surgical margins following lumpectomy of breast cancer. The safety and efficacy of the INTRABEAM® System as a replacement for whole breast irradiation in the treatment of breast cancer has not yet been established.
