Precision Therapeutics, Inc. Presents Multi-Gene Breast Cancer Studies at 2011 Breast Cancer Symposium

9/7/2011 5:53:56 AM

PITTSBURGH, Sept. 7, 2011 /PRNewswire/ -- Precision Therapeutics will present data on four compelling multi-gene breast cancer signatures at the 2011 Breast Cancer Symposium, being held September 8-10, 2011, in San Francisco, California. Precision's abstract, titled, "Evaluation of the Performance of Breast Cancer Cell-Line Derived Multi-Gene Predictors (MGPs) of Chemotherapy Response in Multiple Clinical Trials," demonstrates the feasibility of using these signatures to predict chemotherapy response in breast cancer patients.

Using cancer cell lines to identify pharmacogenomic predictors of patient clinical outcomes may be faster and less costly to perform than utilizing gene expression data from a prospectively collected patient cohort, according to the authors of the abstract.

"Identifying individual patients that are most responsive to specific chemotherapy regimens is clinically useful," says Nan Song, Bioinformatics and Statistic Scientist at Precision Therapeutics. "By combining ChemoFx® chemosensitivity data from cell lines with their genomic profiles, we have developed four unique Multi-Gene Predictors for chemotherapy response from breast cancer cell lines and performed a systematic evaluation of the performance of these gene signatures using data from five distinct clinical trials. The promising results give us hope for helping optimize treatments for breast cancer patients."
