Response Genetics, Inc. Announces Presentations at the American Society of Clinical Oncology's Gastrointestinal Cancers Sympo...

Response Genetics, Inc. (Nasdaq:RGDX), a company focused on the development and sale of molecular diagnostic tests that help determine a patient's response to cancer therapy, today announced that the company will present two abstracts at the upcoming American Society of Clinical Oncology Gastrointestinal (ASCO GI) Cancers Symposium in San Francisco, CA, January 15 to 17, 2015. One presentation, entitled "Expanded KRAS and NRAS assays increase detection of mutations that predict for resistance to therapy in colorectal cancer patients" demonstrates the clinical utility of Response Genetics' proprietary ResponseDX® KRAS and NRAS mutation detection tests in colorectal cancer. The other presentation, entitled "EGFR ligands and ERCC1 mRNA expression to predict clinical outcome in Japanese patients with metastatic colorectal cancer harboring overexpressed EGFR and KRAS exon 2 wild-type treated with cetuximab plus oxaliplatin-based chemotherapy (JACCRO CC-05/06 AR)" provides further clinical evidence for the company's patented ERCC1 mRNA expression technology in predicting response to chemotherapy.

"The innovative presentations at ASCO GI illustrate why ResponseDX® panels should be a first line choice among oncologists for patients" said Response Genetics' Chairman and Chief Executive Officer, Thomas A. Bologna. "As our RAS poster demonstrates, use of our expanded RAS assay identifies an additional 15% of tumors with mutations relative to assays restricted to RAS exon 2. We believe the expanded RAS testing offered by Response Genetics is invaluable in guiding therapy decisions for colorectal cancer patients."
