| Outline of Final Research Achievements |
There is recent concern that widespread PSA testing and extended‐core needle biopsies have led to the overtreatment of PCa, particularly when detected at its early stages. We developed a novel biopsy instrument that extends the side-notch length to 25 mm and the stroke length to 28 mm, and here we report the results of our evaluation of its impact on the detection of prostate cancer in TRNB. The novel biopsy instrument with a 25 mm side-notch can take longer tissue samples safely and has a higher rate of prostate cancer detection in transrectal biopsy. Our data suggest that total length of cancer in cores is the optimal measure of tumor extent in prostate biopsy specimens for identifying small‐volume prostate cancer.
