The Gleason score is the best histopronostic criterion in prostate cancer. Unfortunately, the reproducibility of the Gleason score was poor in iterative analyzes by the same or by other pathologists. Furthermore, prostate cancer is heterogeneous and biopsies do not accurately reflect the actual tumor architecture.

A Gleason score is determined when the biopsy tissue is looked at under the microscope. If there is a cancer, the score indicates how likely it is to spread.

A Gleason score is given to prostate cancer based upon its microscopic appearance. Cancers with a higher Gleason score are more aggressive and have a worse prognosis. Pathological scores range from 2 to 10, with higher numbers indicating greater risks and higher mortality. The Gleason Score ranges from 1-5 and describes how much the cancer from a biopsy looks like healthy tissue (lower score) or abnormal tissue (higher score). Most cancers score a grade of 3 or higher. Since prostate tumors are often made up of cancerous cells that have different grades, two grades are assigned for each patient. Därför ligger Gleasonsumman för prostatacancer vanligtvis mellan 6 och 10, där Gleasonsumman 6 i allmänhet betyder cancer med goda prognoser.

Authors John M Prostate cancer staging is the process by which physicians categorize the risk of cancer having spread beyond the prostate, or equivalently, the probability of being cured with local therapies such as surgery or radiation.Once patients are placed in prognostic categories, this information can contribute to the selection of an optimal approach to treatment.

You may hear this score being called the Gleason Grade. Doctors then work out an overall Gleason score by adding together the 2 most common Gleason grades. So for example, if the most common Gleason grade is 3, and the second most common is 4, then the overall Gleason score is 7. Or they might write the scores separately as 3 + 4 = 7.

The Gleason score is a grade for your prostate cancer, determining how aggressive or nonaggressive it is.

So for example, if the most common Gleason grade is 3, and the second most common is 4, then the overall Gleason score is 7. Or they might write the scores separately as 3 + 4 = 7.

And men with a Gleason score 8 cancer tend to do better than those with a Gleason score of 9 or 10. The scale of the Gleason score can be misleading for patients. For example, a man with a Gleason score 6 cancer might assume that his cancer is in the middle of the range of grades (which in theory go from 2 to 10), even though grade 6 cancers are actually the lowest grade seen in practice.

T1 or T2 prostate cancer,. Gleason score ≤7, PSA ≤20 ng/mL, performance status 0-1. Exclusion. Prostate volume ≥80 cm3, extraprostatic

So Gleason 6 is the lowest, and the best you can have.

En score under 6 har ikke udviklet sig til kræft. Gleason skalaen blev udviklet i 1960'erne og fortsætter med at være en af de mest nøjagtige måder at bestemme aggressiviteten af prostatakræft.
