For example, if the primary tumor grade was 2 and the secondary tumor grade was 3 but some cells were found to be grade 4, the Gleason score would be 2+4=6. This is a slight change from the pre-2005 Gleason system where the second number was the secondary grade (i.e., the grade of the second-most common cell line pattern).
PSA grades millions of cards per year, many worth six or seven figures. Without insurance, collectors face significant financial risk if their cards are lost or damaged, despite PSA’s public assurances of security. The first significantly controversial card grade was in fact the first card ever graded by PSA. This was the T206 Honus Wagner ...
Prostate cancer is a major topic of ongoing research. From 2016 to 2020, over $1.26 billion was invested in prostate cancer research, representing around 5% of global cancer research funds. [122] This places prostate cancer 10th among 18 common cancer types in funding per cancer death, and 9th in funding per disability-adjusted life year lost ...
The GRADE approach separates recommendations following from an evaluation of the evidence as strong or weak. A recommendation to use, or not use an option (e.g. an intervention), should be based on the trade-offs between desirable consequences of following a recommendation on the one hand, and undesirable consequences on the other.
Grading in cancer is distinguished from staging, which is a measure of the extent to which the cancer has spread. Pathology grading systems classify the microscopic cell appearance abnormality and deviations in their rate of growth with the goal of predicting developments at tissue level (see also the 4 major histological changes in dysplasia).

Men with prostate cancer may be characterized as low, intermediate, or high risk for having/developing metastatic disease or dying of prostate cancer. PSA level is one of three variables on which the risk stratification is based; the others are the grade of prostate cancer (Gleason grading system) and the stage of cancer based on physical ...
However, more research is needed to determine the optimal protocols and long-term efficacy of this approach. [77] As research continues, electrochemotherapy may offer new hope for prostate cancer patients, particularly those seeking less invasive treatment options or those for whom traditional therapies have failed.
