Abstract
We present a clinical and molecular study of a series of specific loss of heterozygosity (LOH) indicators which, together with PSA, increase the predictability of cancer in early prostate cancer patients. Considering a positive biopsy as the standard reference, the testing parameters for LOH testing are better than the PSA F/T ratio (<25%), suggesting that this noninvasive approach to detecting early prostate cancer could be very useful as a new tool to optimize the indications for iterative prostate biopsies.
