Prostate cancer screening with PSA is plagued by high rate of unnecessary prostate biopsies, especially in the "gray zone" (4.00ng/ml e 10.99ng/ml). We introduce a new circulating-tumor-cell (CTC) biomarker for detection of prostate cancer in patients in the PSA "gray zone" level, with the clinically verified potential to substantially decrease the number of unnecessary prostate biopsies.
