Radient Pharmaceuticals Submits Two Abstracts to the American Society of Clinical Oncologists on the Increased Sensitivity of Onko-Sure® Combined With CEA for Colorectal Cancer Detection

TUSTIN, CA--(Marketwire - Sep 20, 2011) - Radient Pharmaceuticals Corporation "the Company" or "Radient" (OTCQX: RXPC) (PINKSHEETS: RXPC), a developer and marketer of In Vitro Diagnostic (IVD) cancer tests, today announced it has submitted two scientific abstracts to the American Society of Clinical Oncologists (ASCO). Both abstracts discussed the results of recent studies on the monitoring and screening of colorectral cancer using Onko-Sure® in conjunction with carcinoembryonic antigen (CEA). When Onko-Sure® was used in conjunction with CEA, the sensitivity was 55% higher compared to that of using CEA alone.

Upon acceptance of these abstracts by ASCO, they will be presented at ASCO's 2012 Gastrointestinal Cancers Symposium in San Francisco.

"Radient continues to conduct research that is yielding very positive results for Onko-Sure® as a diagnostic and monitoring tool for colorectal cancer along with many other types of cancers. We look forward to sharing our results with the medical community through presentations at scientific conferences," stated Radient Chairman and CEO Douglas MacLellan.

Onko-Sure® is cleared for market by the US FDA for the treatment and recurrence monitoring of colorectal cancer. Onko-Sure® is a blood test that runs on an ELISA platform and is available through certified clinical reference labs.
