Prostate Needle Biopsy Sampling Techniques: Impact on Pathological DiagnosisThe clinicopathological characteristics of newly diagnosed prostate cancer have significantly changed due to widespread prostate-specific antigen (PSA) screening after its introduction in the late 1980s. The most remarkable change has ...
If your pathologist finds cancer cells in your biopsy, they will use the Gleason Grading System to grade the cancer cells based on how much like healthy cells they look. On your pathology report, you will get a Gleason score (also called a Gleason sum), which is the sum of the scores ...

Fig. 2: Mapping of human prostate cancer models to the trajectory. aProjection of the indicated human cell lines ex vivo and patient-derived xenograft (PDX) models in vivo to the pseudotime (PT) inferred trajectory. Normal prostate: green; hormone-sensitive tumors (HSPC): red; castration-resis...
We conclude that the finding of perineural invasion in needle biopsy of prostatic carcinoma has no independent predictive value for the presence of extraprostatic extension, seminal vesicle involvement, or pathologic stage in the radical prostatectomy. Accordingly, we no longer routinely evaluate this ...
The study found that the saliva panel accurately sorted the men with prostate cancer from those with an enlarged prostate -- something that up to now has required a needle biopsy. "Of course, with all such preliminary studies questions still remain as to the accuracy and reliability of the te...
