[Diagnosis of organ-confined prostate cancer by systematic biopsy under guidance of TRUS].
Systematic biopsy is useful to diagnose of prostate cancer. However, the usefulness of systematic biopsy for detection of organ-confined prostate cancer is unclear. There are three biopsy parameters, 1) percentage of biopsy cores involved with cancer (number of cores involves with cancer divided by total number of biopsy cores), 2) millimeters of cancer per biopsy core (total millimeters of cancer in the biopsy specimen divided by total number of biopsy cores) and 3) percentage of cancer in the biopsy specimen (total millimeters of cancer in the biopsy specimen divided by total millimeters of biopsy tissue). Although each biopsy parameter alone is not sufficient to detect organ-confined prostate cancer, the combination with these biopsy parameters and serum prostate-specific antigen levels improved the detection rates of organ-confined prostate cancer.
