Peer-Reviewed Study with Maccabi Health Services Shows Significant Odds Ratio between ColonFlag Tool and CRC Diagnosis

KFAR MALAL, Israel, March 7, 2017 /PRNewswire/ --

Medial EarlySign (, a developer

of machine learning tools for data driven medicine, today announced new research with one of Israel's leading integrated delivery networks, Maccabi Health Services (MHS), that found the company's MeScore (hereafter 'ColonFlag') tool can potentially be used to identify individuals who are at 10 to 20 times increased risk of harboring an occult colorectal cancer (CRC).

The peer-reviewed study, published by PLOS ONE, sought to determine if information contained in complete blood count (CBC) reports could be processed automatically and used to predict the presence of occult CRC in the setting of a large health services plan. The researchers reviewed Maccabi's CBC reports for 112,584 study subjects, of whom 133 were diagnosed with CRC in 2008, and analyzed these with Medial EarlySign's tool.

"Leveraging our advanced EMR database, the results of this performance analysis indicate that ColonFlag can help identify individuals in the population who should be sent for further evaluation for CRC, including those with no clinical signs or symptoms of CRC," said Revital Kariv, Chief Gastroenterologist of Maccabi Health Services.

This is the first time that ColonFlag has been evaluated on previously collected prospective data. When using a 1% cut-off, the odds ratio for colorectal cancer was 21.9, while a 3% cut-off yielded an odds ratio of 10.9, significantly higher than traditional indicators. Current clinical indicators to estimate the risk of colorectal cancer include family history, lifestyle factors such as smoking and physical exercise, obesity, diabetes and laboratory results. These indicators influence a doctor's decision about which screening tool to use, whether it be a fecal occult blood test (FOBT) or colonoscopy. For some of the indicators, research shows 1.5-2.5 times higher risk than the average population.

Reviewing the charts of patients diagnosed with colorectal cancer, the researchers found that for the majority of individuals with cancer, CRC was not suspected at the time of the blood draw.  The study also indicated that frequent use of anticoagulants, presence of other GI pathologies, and non-GI malignancies were associated with false positive ColonFlags.  

"Our research opens the door to further insights relating to the successful performance of ColonFlag and an understanding of how false positives may bear other significant clinical implications," said Dr. Ran Goshen, Chief Medical Officer of Medial EarlySign.

Maccabi operates six regional centers, including 150 branches and clinics, providing full access to Maccabi Healthcare services for all members throughout the country. The organization invests significant resources in research and the acquisition of innovative and managerial systems which promote its medical and administrative organization.
