Journal List Rev Urol v. These cores were analyzed together with the first 6 a total of 14 cores and were labeled as extended biopsy. The role of magnetic resonance imaging in targeting prostate cancer in patients with previous negative biopsies and elevated prostate-specific antigen levels.
Targeted biopsy: benefits and limitations. In patients with no palpable nodule but increased PSA levels, the cancer detection rate doubled when using biopsies of 10 to 14 cores compared to the sextant technique
In Press. Researchers have demonstrated that simultaneously including 3 biopsy cores in the same cassette can lead to the loss of a mean length of 1. Essentially, a sextant is intensely personal to each navigator, and he or she will choose whichever model has the features which suit them best.
Conclusions The apex is a common site of cancers detected by traditional biopsy and of missed cancers found on repeat biopsy. Although increasing the number of biopsy cores has led to increased prostate cancer detection rates, many cancers diagnosed on extended sampling are small, low grade, and potentially indolent.
An analysis of the frequency of the cancers identified in the cores of the sextant and the extended biopsies was undertaken and the results evaluated comparatively. Wszolek MF 1. Abstract Purpose of review A variety techniques have emerged for optimization of prostate biopsy.
We sought to determine whether knowing if the prostate biopsy was positive on 1 side or both sides contributed to assessment of risk of serologic relapse. MRI-targeted biopsy has been proposed as a way to improve detection rates and risk stratification, as well as reduce the number of cores.
Conversely, in those cases where no tumor was found in the core biopsy, only 8. Mojtahed A 2 ,. JAMA , —
