The stearic acid/oleic acid ratio from red blood cells is a marker for the presence of malignant tissue, particularly with prostate cancer. In tumors, the net result of changes in fatty acid metabolism is low stearic acid and high oleic acid, causing a profound shift in the ratio of stearic to oleic acids. One likely outcome of this shift is increased fluidity of the tumor cell membrane, resulting in more rapid movement of nutrients and waste products and allowing for faster metabolic rate. The stearic/oleic ratio is used to monitor the effectiveness of cancer therapy.
Values below 1.1 are associated with malignancy.
