PHILADELPHIA and REHOVOT, Israel, June 6, 2013 /PRNewswire/ -- Rosetta Genomics Ltd. (NASDAQ: ROSG), a leading developer and provider of microRNA-based molecular diagnostics, announces that a manuscript reporting data validating the clinical utility of the Rosetta Cancer Origin Test™ (formerly miRview® mets2) to identify the tumor of origin in Cancer of Unknown or Uncertain Primary (CUP) has been accepted for publication in the peer-reviewed on-line journal Molecular Cancer. The article, titled "Novel microRNA-based assay demonstrates 92% agreement with diagnosis based on clinicopathologic and management data in a cohort of patients with carcinoma of unknown primary," represents the seventh peer-reviewed publication relating to our CUP assays, and the fifth peer-reviewed publication relating to post market validation studies demonstrating the Cancer Origin Test's ability to identify tumor origin in CUP with 92% concordance, the highest level of accuracy of any similar study published to date.
The manuscript discusses the performance of the Cancer Origin Test, an assay utilizing 64 microRNAs to identify 42 tumor types, in formalin-fixed paraffin-embedded (FFPE) samples from 84 CUP patients The results showed concordance with the final diagnosis in 92% of patients; representing an improvement in agreement of 22 percentage points from presentation diagnosis to final diagnosis, which final diagnosis was achieved after more precise clinical and pathological data was added to the data relied upon for the patient's initial assessment.
"MicroRNAs are particularly well-suited as biomarkers for identifying tumor origin as their expression levels and profile reflects tissue origin. Importantly, microRNAs have been shown to be highly stable in tissue block
