Not All Men With Gleason 8

Prostate Cancer 101: The Gleason Score Demystified

There is a perception among a lot of patients especially when they get diagnosed that having a high Gleason score of 8, 9, or 10 is essentially a death sentence, regardless of how they get treated. This is not actually the case at all. Plenty of men with Gleason 8 to 10 disease actually do well after treatment. And it has long been assumed that this was the case in particular if they were identified and treated early while they had truly organ-confined disease.

A newly published paper by Fischer et al. has now confirmed this assumption through a careful retrospective analysis of data from > 450 men whose records could be identified in the SEARCH database, all of whom received surgical treatment for Gleason 8 to 10 prostate cancer.

Fischer and his colleagues set out to identify whether, among a large cohort of men who had pathologic Gleason scores of 8 to 10 after surgery, they could identify particular subsets who were at meaningfully greater of lesser risk for biochemical progression within 2 years of their surgery. To do this, they identified a total of 459 eligible patients within the SEARCH database and categorized these men into one of five different groups:

They then used the data from these five groups of men to compare their risks for biochemical recurrence at 2 years, showing the following findings:

  • Similar results were observed after adjustments were made to allow for variations in PSA level, age, and clinical stage.

    my thinking was that if cancer cells go after your testosterone which is in your prostate then get rid of it completely. plus radiation would of just shrunk the tumor. my cancer would of inevitably came back.so i had them both taken out. the 1 down fall of all this is that my erectile disfunction will never be normal again unless i go and have major surgery for implants since all my tissues were taken during the operation. so for me you can radiate til the cows come home but unless you get rid of the prostate where the cancer is living, it will keep coming back.

    What Do The Results Mean

    A higher Gleason score indicates more aggressive prostate cancer. Typically, lower scores suggest a less aggressive cancer.

    In most cases, scores range between 610. Doctors do not often use biopsy samples that score 1 or 2, as they are not usually the predominant areas of the cancer.

    A Gleason score of 6 tends to be the lowest possible score. A doctor will describe prostate cancer with a score of 6 as being well differentiated, or low grade. This means that the cancer is more likely to have a slower rate of growth.

    Scores in the 810 region are poorly differentiated, or high grade. In these cases, the cancer is likely to spread and grow quickly. The growth rates of cancers with a score of 9 or 10 are likely to be twice as high as those of a cancer with a score of 8.

    A score of 7 can be broken down in two ways:

    This distinction indicates how aggressive the tumor is. Scores of 3 + 4 typically have a good outlook. A score of 4 + 3 is more likely to grow and spread than the 3 + 4 score, but less likely to grow and spread than a score of 8.

    Some people receive multiple Gleason scores. This is because the grade may vary between samples of the same tumor or between two or more tumors.

    In these cases, doctors are likely to use the higher score as the guide for treatment.

    The Gleason score is an important tool for doctors when deciding on the best course of treatment. However, additional factors and grouping systems can assist them in making this decision.

    What Does It Mean If My Biopsy Mentions That There Is Perineural Invasion

    Perineural invasion means that cancer cells were seen surrounding or tracking along a nerve fiber within the prostate. When this is found on a biopsy, it means that there is a higher chance that the cancer has spread outside the prostate. Still, perineural invasion doesnt mean that the cancer has spread, and other factors, such as the Gleason score and amount of cancer in the cores, are more important. In some cases, finding perineural invasion may affect treatment, so if your report mentions perineural invasion, you should discuss it with your doctor.

    Gleason Score For Grading Prostate Cancer

    Figure 1 from Automatic gleason grading of prostate cancer using Gabor ...

    Prostate cancer is also given a grade called a Gleason score. This score is based on how much the cancer looks like healthy tissue when viewed under a microscope. Less aggressive tumors generally look more like healthy tissue. Tumors that are more aggressive are likely to grow and spread to other parts of the body. They look less like healthy tissue.

    The Gleason scoring system is the most common prostate cancer grading system used. The pathologist looks at how the cancer cells are arranged in the prostate and assigns a score on a scale of 3 to 5 from 2 different locations. Cancer cells that look similar to healthy cells receive a low score. Cancer cells that look less like healthy cells or look more aggressive receive a higher score. To assign the numbers, the pathologist determines the main pattern of cell growth, which is the area where the cancer is most obvious, and then looks for another area of growth. The doctor then gives each area a score from 3 to 5. The scores are added together to come up with an overall score between 6 and 10.

    Gleason scores of 5 or lower are not used. The lowest Gleason score is 6, which is a low-grade cancer. A Gleason score of 7 is a medium-grade cancer, and a score of 8, 9, or 10 is a high-grade cancer. A lower-grade cancer grows more slowly and is less likely to spread than a high-grade cancer.

    Understanding Your Pathology Report: Prostate Cancer

    When your prostate was biopsied, the samples taken were studied under the microscope by a specialized doctor with many years of training called a pathologist. The pathologist sends your doctor a report that gives a diagnosis for each sample taken. Information in this report will be used to help manage your care. The questions and answers that follow are meant to help you understand medical language you might find in the pathology report from your prostate biopsy.

    Grade Groups Of Prostate Cancer

    The Grade Group is the most common system doctors use to grade prostate cancer. It is also known as the Gleason score.

    The grade of a cancer tells you how much the cancer cells look like normal cells. This gives your doctor an idea of how the cancer might behave and what treatment you need.

    What Does It Mean If My Biopsy Report Mentions The Word Core

    The most common type of prostate biopsy is a core needle biopsy. For this procedure, the doctor inserts a thin, hollow needle into the prostate gland. When the needle is pulled out it removes a small cylinder of prostate tissue called a core. This is often repeated several times to sample different areas of the prostate.

    Your pathology report will list each core separately by a number assigned to it by the pathologist, with each core having its own diagnosis. If cancer or some other problem is found, it is often not in every core, so you need to look at the diagnoses for all of the cores to know what is going on with you.

    Survival By Tumor Grade

    Understanding The Gleason Score | Prostate Cancer Staging Guide

    One way cancer is staged is by looking at the grade of cancer. Grade refers to how cancer cells look like under a microscope.

    Traditionally for prostate cancer, this has been done using the Gleason Score, which was developed in the 1960s. Under this system, cancerous cells are categorized on a scale from 1 to 5. Grade 1 cells are considered normal prostate tissues, while cells in the grade 5 range have mutated to such an extent they no longer resemble normal cells.

    In determining a Gleason score, a pathologist will examine a biopsy sample under a microscope and give a Gleason grade using the above scale to the most predominant pattern displayed, then a second grade to the pattern that is the second most predominant. Those two grades are then added to form the overall Gleason score .

    In theory, Gleason scores could range from 2 to 10, but pathologists today rarely give a score between 2 and 5 and are more likely to be in the range of 6 to 10 with 6 being the lowest grade of prostate cancer.

    Under the Gleason Score system, a 6 is considered low grade, 7 is intermediate and scores of 8, 9, or 10 are considered high-grade cancers.

    The higher the Gleason score, the more likely it is the prostate cancer will grow and spread quickly.

    However, there have been some issues with the Gleason system, and a new grading system, to act as an extension of the Gleason system, has been developed.

    Under this system Gleason scores are now categorized into grade groups:

    Outlook For Men With Localised Prostate Cancer

    Most localised prostate cancer is slow-growing and may not need treatment or shorten a mans life. For many men who have treatment for localised prostate cancer, the treatment will get rid of the cancer. For others, treatment may be less successful and the cancer may come back. If this happens, you might need further treatment.

    What Does It Mean If In Addition To Cancer My Biopsy Report Also Says Acute Inflammation Or Chronic Inflammation

    Inflammation of the prostate is called prostatitis. Most cases of prostatitis reported on a biopsy are not caused by infection and do not need to be treated. In some cases, inflammation may increase you PSA level, but it is not linked to prostate cancer. The finding of prostatitis on a biopsy of someone with cancer does not affect their prognosis or the way the cancer is treated.

    What Does It Mean If My Biopsy Report Also Mentions Atrophy Adenosis Or Atypical Adenomatous Hyperplasia

    All of these are terms for things the pathologist might see under the microscope that are benign , but that sometimes can look like cancer.

    Atrophy is a term used to describe shrinkage of prostate tissue . When it affects the entire prostate gland it is called diffuse atrophy. This is most often caused by hormones or radiation therapy to the prostate. When atrophy only affects certain areas of the prostate, it is called focal atrophy. Focal atrophy can sometimes look like prostate cancer under the microscope.

    Atypical adenomatous hyperplasia is another benign condition that can sometimes be seen on a prostate biopsy.

    Finding any of these is not important if prostate cancer is also present.

    What Does It Mean To Have A Gleason Score Of 6 Or 7 Or 8

    The lowest Gleason Score of a cancer found on a prostate biopsy is 6. These cancers may be called well-differentiated or low-grade and are likely to be less aggressive – they tend to grow and spread slowly.

    Cancers with Gleason Scores of 8 to 10 may be called poorly differentiated or high grade. These cancers tend to be aggressive, meaning they are likely to grow and spread more quickly.

    Cancers with a Gleason Score of 7 may be called moderately differentiated or intermediate grade. The rate at which they grow and spread tends to be in between the other 2.

    How Prostate Cancer Is Diagnosed And Staged

    Cancer staging helps you and your doctor understand how advanced your cancer is and how much it has spread at the time of diagnosis. Knowing your cancer stage also helps your doctor determine the best treatment options for you and estimate your chance of survival.

    The most widely used staging system for cancer is the TNM system that classifies cancer from stage 1 to stage 4.

    TNM stands for:

    • Tumor: the size and extent of the tumor
    • Nodes: the number or extent of nearby lymph node involvement
    • Metastasis: whether cancer has spread to distant sites in the body

    The TNM scale is used for many types of cancer. When a doctor uses it to determine your prostate cancer stage, theyll consider several other factors as well, including:

    Survival For All Stages Of Prostate Cancer

    Generally for men with prostate cancer in England:

    • more than 95 out of 100 will survive their cancer for 1 year or more
    • more than 85 out of 100 will survive their cancer for 5 years or more
    • almost 80 out of 100 will survive their cancer for 10 years or more

    Survival for prostate cancer is also reported in Scotland and Northern Ireland. But it is difficult to compare survival between these countries because of differences in the way the information is collected.

    Cancer survival by stage at diagnosis for England, 2019Office for National Statistics

    These statistics are for net survival. Net survival estimates the number of people who survive their cancer rather than calculating the number of people diagnosed with cancer who are still alive. In other words, it is the survival of cancer patients after taking into account the background mortality that they would have experienced if they had not had cancer.

    Can The Gleason Score On My Biopsy Really Tell What The Cancer Grade Is In The Entire Prostate

    Treating High-Risk Gleason 8: A Modern Approach | Mark Scholz, MD | PCRI

    Because prostate biopsies are tissue samples from different areas of the prostate, the Gleason score on biopsy usually reflects your cancers true grade. However, in about 1 out of 5 cases the biopsy grade is lower than the true grade because the biopsy misses a higher grade area of the cancer. It can work the other way, too, with the true grade of the tumor being lower than what is seen on the biopsy.

    Tests To Identify Prostate Cancer Stage

    After a prostate cancer diagnosis, your doctor will do tests to see how far the cancer has spread. Not all men need every test. It depends on the results of your biopsy, a test that checks tissue from your prostate gland for cancer. Tests that help your doctor figure out the stage of your prostate cancer include:

    • CT scan of the abdomen and pelvis to see if the cancer has spread
    • Nuclear medicine bone scan to see if the cancer has spread to your bones
    • Surgery to check the lymph nodes in your pelvis for prostate cancer spread

    What Is A Bad Gleason Score For Prostate Cancer

    Gleason scores aren’t good or bad, per se. They predict how quickly your prostate cancer might grow. Tumors with higher Gleason scores are likely to grow quickly. And Gleason scores aren’t the only factors healthcare providers consider when creating your treatment plan.

    What other factors do healthcare providers consider?

    Providers consider the results of other tests and additional biopsy information. For example, when you had your biopsy, your healthcare provider obtained several samples or cores from your prostate. They checked how many cores contained cancer and whether most of the cells in the cores were cancerous cells.

    Other factors may include:

    How Do Doctors Find Out Your Grade Group

    The pathologist grades each sample of prostate cancer cells from 3 to 5 based on how quickly they are likely to grow or how aggressive the cells look. 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. This combined score is now called the Grade Group.

    There are 5 Grade Groups. Grade Group 1 is the least aggressive and Grade Group 5 is the most aggressive.

    This is how the Gleason score and Grade Groups match up and what it means:

    Survival Outcomes In Gleason 9

    Symptoms of Enlarged Prostate

    Radiation therapy and radical prostatectomy offer men with Gleason score 910 prostate cancer equivalent cancer-specific and overall survival, according to a new study.

    Findings also suggest that extremely dose-escalated radiation therapy plus androgen deprivation therapy might be the optimal upfront treatment for these patients, researchers concluded in a paper published online ahead of print in European Urology.

    The investigators noted that their study is the largest comparative study of outcomes exclusively for patients with Gleason score 910 PCa.

    The study, led by Amar U. Kishan, MD, of the University of California Los Angeles, included 487 patients with biopsy Gleason 910 disease. Of these, 230 underwent external beam radiation therapy , 87 were treated with EBRT and brachytherapy , and 170 underwent RP. Most radiation therapy patients received androgen deprivation therapy and dose-escalated radiation therapy.

    The median follow-up was 4.6 years. Local salvage and systemic salvage were performed more frequently among RP patients when compared with EBRT patients or EBRT plus BT patients , Dr. Kishans group reported.

    The 5-year and 10-year distant metastasis-free survival rates were significantly higher with EBRT plus BT than with EBRT or RP .

    They noted that nearly 94% of EBRT patients had upfront ADT with a median duration of 24 months and 97% of EBRT patients received doses isoeffective to, or higher than, 75.6 Gy in 1.8-Gy fractions.
