Blood Test Detects Gastrointestinal Cancers

David Wolpin, M.D. MPH of the Dana-Farber Cancer Institute discussed with online periodical MedPage Today the results of his research on detecting gastrointestinal cancers with a simple blood test. The test is not yet commercially available and is still in its developmental stages. The blood test did not detect cancer in 2000 cancer free individuals but did find it in the 135 GI cancer patients being evaluated at the Dana-Farber Cancer Institute. In most cases they were able to pinpoint the location of the malignancy in the GI tract based on the testing used. The more advanced the cancer, the more accurate the blood test was.

The report was part of a larger study named the Circulating Cell-Free Genome Study. This is a multi-center trial looking at over 15,000 individual patients from over 142 different medical institutions. The hope is that as the sophistication and accuracy of the test are improved, the ability of physicians to detect cancers early would improve as well.

Dr. Wolpin reminds us that most cancers that occur in the gastrointestinal tract are difficult to find and screen for and are detected at an advanced stage. He hopes that lives can be saved by finding the cancers early with a simple blood test.
