PITTSBURGH--(BUSINESS WIRE)--Precision Therapeutics announces the release of a study, developed by physicians from the University of Pittsburgh Medical Center, Columbia University, the University of Kentucky Medical Center and the University of Texas MD Anderson Cancer Center. Initial findings were accepted for publication in conjunction with the American Society of Clinical Oncology (ASCO) Annual Meeting, being held June 1-5, 2012 in Chicago, Illinois.
The study titled, In Vitro Chemoresponse Assay Results and Population Clinical Response Rates in Women with Ovarian Cancer, begins to answer the clinical question of whether the ChemoFx® in vitro drug response marker can be used to help determine tumor response to platinum chemotherapy agents. An evaluation of ChemoFx results for carboplatin/paclitaxel from 3,130 patient tumors with primary or recurrent epithelial ovarian cancers was conducted. Tumor response was classified as responsive, intermediately responsive, or non-responsive to chemotherapy. Responsive and intermediately responsive rates were combined in order to create a response rate for carboplatin/paclitaxel. The rates of pan-resistance, or non-responsive to all agents tested, was also examined in both primary and recurrent tumors. Findings showed ChemoFx response rates to carboplatin/paclitaxel were consistent with published population response rates for ovarian cancer and as expected, more aggressive histologic subtypes were less responsive to carboplatin/paclitaxel. This data suggests that ChemoFx provides tumor-specific information which may assist physicians in choosing individualized chemotherapy treatment plans for ovarian cancer patients.
“This intriguing data may one day help us in the personalization of chemotherapy for women with ovarian cancer,” says Dr. Scott Richard, lead author of the abstract. It is estimated that approximately 22,000 women in the United States will develop ovarian cancer in 2012.
