SAN ANTONIO, TX -- December 16, 2002 -- Protein chip mass spectrometry may be able to identify breast cancer-associated protein profile panels, which can lead to a simple blood test for cancer detection.

Lori L. Wilson, MD, Eastern Virginia Medical School, Norfolk, Virginia, United States, presented study results at the 25th Annual Meeting of the San Antonio Breast Cancer Symposium.

While mammography remains the screening test of choice for breast cancer, Dr. Wilson said, this method fails to detect up to 20 percent of cancers.

"Currently, there are no single protein markers available for breast cancer screening," Dr. Wilson said. "Identification and analysis of a protein panel profile appears to have a greater potential for overcoming this limitation."

Dr. Wilson and colleagues at Eastern Virginia Medical School have used a procedure that combines SELDI (Surface Enhanced Laser Desorption Ionization)-TOF (Time of Flight) Protein Chip
