Biopsy Gleason Score: Two Gleason Grade numbers are added together to produce the Gleason score. A biopsy Gleason score once could range from 2 to 10, but with advances in staining technology, more commonly ranges between 6 and 10. The first Gleason Grade number indicates the Gleason Grade of the cancer cells found most commonly within the sample, the second number represents the second most commonly found grade. Higher Gleason scores are associated with increased cancer aggressiveness.
Specimen Type: A core needle biopsy is the main method used to diagnose prostate cancer.
# of Positive Cores: The number of biopsy cores that contain cancer.
Clinical Stage: The clinical stage is the best estimate of the extent of the disease, based on the results of the physical exam, lab tests, prostate biopsy, and any imaging tests.
