Is the blood marker LPA (lysophosphatidic acid) an effective screening tool for ovarian cancer?
LPA or lysophosphatidic acid is a substance that stimulates the growth of ovarian tumors. One small study found that levels of LPA in blood plasma are elevated in about 90% of women with early ovarian cancer. There are clinical trials going on presently to determine the effectiveness of LPA in detecting ovarian cancer. (JAMA, August 26, 1998) However, it is still to early to know if this test will be a good screening tool. This test is not yet available to the public.
