BOCA RATON, Fla., July 21 /PRNewswire/ -- Researchers from Florida
Atlantic University, the Center for Breast Care at the Women's Center at Boca
Raton Community Hospital, and MeVis, The Center for Diagnostic Systems and
Visualization at the University of Breman, Germany have developed new
techniques to aid clinicians in the diagnosis and treatment of breast cancer.
They have developed and piloted a unique software platform utilizing
computational clinical imaging techniques for the analysis and display of
serial-time MRI, which is showing great promise in the early detection and
treatment of breast cancer.
These FDA-approved techniques were developed at MeVis, The Center for
Diagnostics Systems and Visualization, under the direction of Dr. Heinz-Otto
Peitgen, who is also a faculty member in the department of mathematical
sciences at FAU's Charles E. Schmidt College of Science. Peitgen used the
mathematical concept of fractals to begin developing this unique software.
"Fractals are large, irregular geometric patterns made up of infinitely
smaller, but identical, irregular patterns," said Peitgen. "Fractal theory
provided an appropriate platform upon which to build the software program
because the ducts within human breast tissue have fractal properties."
Breast MRI is a relatively new tool used by physicians to diagnose breast
cancer as an adjunct to conventional mammography. Breast MRI displays the
behavior of a cancerous lesion in three dimensions and approaches a nearly
100 percent accuracy rate in the detection of invasive cancer. In contrast,
mammography provides a two-dimensional view of the breast and surrounding
tissue and only detects 80 to 85 percent of tumors. One of the main strengths
of MRI is its precise delineation of soft tissue and its ability to image the
breast in fine sections dynamically by taking multiple MRI images over time.
The percentage of medical centers doing breast MRI is small, but growing.
A recent study spearheaded by Dr. Kathy Schilling, medical director of
Imaging and Intervention at the Center for Breast Care at the Women's Center
at Boca Raton Community Hospital, was published in The American Journal of
Radiology and entitled "Assessment of Suspected Breast Cancer by MRI - A
Prospective Clinical Trial Using a Combined Kinetic and Morphologic Analysis."
Findings of this study showed that in over 30 percent of patients there were
additional tumors in the same breast, and in almost 10 percent of the patients
there were tumors in the opposite breast.
"These tumors were not found using mammography or ultrasound," said
Schilling. "We also found a resulting change in the course of treatment in
nearly 25 percent of patients undergoing surgery for newly diagnosed breast
cancer." In addition, findings from this study showed that MRI directed
biopsies using computational clinical imaging led to definitive conclusions,
demonstrating the clinical utility of this unique approach.
According to Dr. Roger Goldwyn, faculty member in FAU's department of
mathematical sciences and director of the proposed Center for the Development
of Computational Clinical Imaging at FAU, "Our approach is to use innovative
image-processing tools to find additional tumors and to help determine patient
management outcomes. These techniques have also led to biopsies directed by
these image-processing tools, surgical planning modifications, and monitoring
effectiveness of chemotherapy."
The Center for Breast Care at Boca Raton Community Hospital is a high
volume center, handling more than 45,000 cases per year and finding more than
320 new breast cancers annually. In conjunction with FAU, the Center for
Breast Care is developing their expertise in the use of computer-aided
clinical imaging to assist clinicians nationwide. The integration of this
software into general imaging departments involved in breast cancer diagnosis
will enable better care, a reduction in costs for unnecessary surgeries, and
ultimately result in improved patient survival. The Center for Breast Care is
also working with experts at FAU in the university's medical school program to
further develop these specialized tools and continue to evaluate them in pilot
studies to examine their ability to save lives.
"Our researchers at FAU will continue to conduct clinical evaluations and
collaborate with the Center for Breast Care and MeVis to further develop these
tools for use by clinicians in more routine settings in order to have a wider
impact on patient care," said Dr. Larry F. Lemanski, vice president for
research at FAU.
American women have a one in nine chance of developing breast cancer
during their lifetime. Early detection is the single most effective tool in
fighting breast cancer. The sooner the cancer is detected, the more options a
woman has for treatment and the better her chance for survival. Methods for
detection include mammography -- a safe, low-dose x-ray of the breast -- that
can be a vital tool in helping to discover small lumps up to two years before
they can be felt in a physical exam. With mammography, however, only 80 to 85
percent of tumors are detected, leaving 15-20 percent of tumors undetected.
These undetected tumors will enlarge and become more lethal before they are
identified in a later screening or when they become clinically apparent.
