Objectives. Many men with negative prostate biopsies and persistently elevated serum total
prostate-specific antigen (tPSA) values will have cancer detected on a repeated biopsy. An …

Purpose: Several studies suggest that sextant transrectal ultrasound guided biopsy of the
prostate provides insufficient material to detect all clinically important prostate cancer, and …

OBJECTIVES: To investigate the impact of additional biopsy cores on prostate cancer
diagnosis among US veterans. The reported rate of positive biopsy results varies from 20 …

Objectives To compare, in a retrospective study, pathological specimens of prostate cancer
detected in additional areas of a 12‐core biopsy with tumours detected using traditional …

OBJECTIVES: The number of cores obtained during transrectal ultrasound-guided prostate
biopsy to detect cancer has increased from the previous standard of 6. Increasing the …

Objectives. To compare the cancer detection of two consecutive sets of prostate biopsies
using either the sextant or the 10-core technique. Methods. Ninety-one specimens after …

Materials and methods We retrospectively analyzed pathology reports of 197 patients (2196
biopsy cores) undergoing initial transrectal ultrasound guided biopsy. A multivariate analysis …

Purpose: We investigated the relationship between prostate volume and cancer detection by
needle biopsy, and determined the effect of an increased number of cores on the sampling …

Purpose: In this study we assessed the relative yield of 10 core biopsy, and the whole range
of alternative 8 and 6 core biopsy protocols over that of the classic sextant biopsy protocol …

Purpose: The systematic sextant biopsy is currently the gold standard for the tissue
diagnosis of prostate cancer. However, it is unknown whether this 6 core approach provides …
