Can a Simple Blood Test Diagnose Cancer?

logo1267406_mdA new study presented at the Anesthesiology 2013 annual meeting reported that a simple blood test can detect early stage lung and prostate cancers as well as their recurrences. They said serum-free fatty acids and their metabolites can be used as screening biomarkers to help diagnose early stages of cancer and to identify the probability of recovery and recurrence after tumor removal.

The researchers looked at blood samples from 56 patients with lung cancer and 40 with prostate cancer and compared them to blood samples from people without cancer. In addition, blood was examined from from 24 patients scheduled for curative lung cancer surgery, and again six and 24 hours after surgery. The cancer patients has one-to six-times greater concentrations of serum-free fatty acids and their metabolites (biomarkers) in the blood thank patients without cancer. In the surgical group the serum free fatty acids and concentrations decreased by three to 10 times within 24 hours after the tumors were removed. The researchers said “In this study, we identified compounds that appear to be new screening biomarkers in cancer diagnosis and progress.” The head of research said “This is an exciting first step to having an uncomplicated way to detect early stages of lung, prostate and perhaps other cancers.”  It could also be used to measure the success of tumor resection surgery, immediately after surgery and long-term for recurrence screening.?”
