A new prostate cancer grading system initially to be used in parallel to the Gleason system has been developed that is simpler and more accurately reflects prognosis. Rationale: Despite the above changes to the Gleason system, there are still significant deficiencies in its reporting that are described below that have led to a new grading system for prostate cancer.
Gleason scores are no longer assigned on needle biopsy and Gleason scores are virtually never diagnosed on other types of prostate samples. Bizonytalanság esetén Gl. Ha a terápiás válasznak nincs szöveti jele, puffadt cpl-jú, vagy zsugorodott sejtekazt meg kell említeni a leletben. Intraductal carcinoma of the prostate in the absence of invasive component should not be graded but should be commented on in the report to alert clinicians of its consistent association with aggressive cancer Intraductal carcinoma of the prostate IDC-P should not be assigned a Gleason grade, yet it is typically associated with aggressive disease.
Rationale: IDC-P usually represents extension of high-grade invasive carcinoma into ducts and is typically seen with Gleason scores 7 or higher cancer. However, uncommonly, IDC-P can represent a precursor lesion without adjacent invasive cancer.
Consequently, IDC-P is not given a grade.
However, in the uncommon setting in which there is only IDC-P on biopsy in the absence of infiltrating carcinoma, a note is added to the pathology report stating that IDC-P is typically associated with high-grade invasive carcinoma and it is justified to treat these patients definitively with surgery or radiation therapy.
Rationale: When a tumor is almost entirely high grade, it is expected that the tumor will be aggressive, even if there is a very small focus of lowergrade cancer.
In the setting of three patterns on needle biopsy i.
Rationale: On needle biopsy, it is thought that any pattern 5 on needle biopsy, even if it is the third most common pattern, is significant and should be incorporated into the Gleason score; it would likely not be so limited if it was not for undersampling on needle biopsy.
Minor HG pattern! Experts in prostate pathology have used this grading rule in the past with outcome prostate cancer acinar type demonstrating that grading each major nodule separately correlates well with prognosis.
