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 My Gleason Score Mean
A Gleason score predicts how fast your prostate cancer is growing. Named after Dr. Donald Gleason, the pathologist who developed this system in the 1960s, its commonly used today and is one of the most important measurements in a prostate cancer pathology report.
The Gleason score consists of two numbers called grades, which range from 1-5. Grade 1 indicates slow growth prostate cancer, and grade 5 is rapidly growing cancer. There are two numbers, known as the primary and secondary grade that are used to get the Gleason score.
The primary grade is given based on the predominant cell pattern seen in the cells of a needle core biopsy. The second number, the secondary grade, is the next most common cell pattern seen in the biopsy. These two grades are then added to get the Gleason score. The table below shows what each score indicates for the rate of cancer growth.

An enlarged prostate can also be the cause of other problems. If the enlarged prostate is causing symptoms, the best treatment would be a natural remedy. In the meantime, there are treatments for a wide range of conditions that cause a man to experience pain. A common surgical procedure involves an electric loop, laser, or electro-stimulation. The procedure is a safe and effective option for treating enlarged or symptomatic BPH.

Gleason Prostate Cancer Score
1960s as a way to measure how aggressive your prostate cancer may be.
A pathologist determines your Gleason score by looking at a biopsy of your prostate tissue under a microscope. They grade the cells in the biopsy on a scale of 1 to 5. Grade 1 cells are healthy prostate, whereas grade 5 cells are highly mutated and dont resemble healthy cells at all.
The pathologist will calculate your Gleason score by adding together the number of the most prevalent type of cell in the sample and the second most prevalent type of cell.
For example, if the most common cell grade in your sample is 4 and the second most common is 4, you would have a score of 8.
A Gleason score of 6 is considered low-grade cancer, 7 is intermediate, and 8 to 10 is high-grade cancer.

Initial Treatment Of Prostate Cancer By Stage And Risk Group
The stage of your cancer is one of the most important factors in choosing the best way to treat it. Prostate cancer is staged based on the extent of the cancer and the PSA level and Gleason score when it is first diagnosed.
For prostate cancers that haven’t spread , doctors also use risk groups to help determine if more tests should be done and to help guide treatment options. Risk groups range from very-low-risk to very-high-risk, with cancers in the lower risk groups having a smaller chance of growing and spreading compared to those in higher risk groups.
Other factors, such as your age, overall health, life expectancy, and personal preferences are also important when looking at treatment options. In fact, many doctors determine a mans possible treatment options based not just on the stage, but on the risk of cancer coming back after the initial treatment and on the mans life expectancy.
You might want to ask your doctor what factors he or she is considering when discussing your treatment options. Some doctors might recommend options that are different from those listed here. Taking part in a clinical trial of newer treatments is also an option for many men with prostate cancer.

Stages Of Prostate Cancer
Doctors combine the T, N, and M results with the Gleason score and PSA level in a process called stage grouping. The system uses Roman numerals from I to IV . The stage helps your doctor choose the best course of treatment for you.
Stage I
- The cancer is growing in your prostate but hasnât spread beyond it.
- In most cases, the doctor canât feel the tumor during a DRE or see it in imaging tests.
- The Gleason score is 6 or less, and the PSA level is less than 10.
- The tumor is in half or less of one side of the prostate.
Stage IIA
- The cancer is growing in your prostate but hasnât spread beyond it.
- The doctor may or may not be able to feel the tumor during a DRE or see it on an imaging test.
- The tumor can touch more than half of one lobe of the prostate but doesnât involve both lobes.
- The Gleason score is 7 or less, and the PSA level is less than 20.
Stage IIB
- The cancer is growing in your prostate but hasnât spread beyond it.
- The doctor may or may not be able to feel the tumor during a DRE or see it on an imaging test.
- The tumor can be in one or both lobes of the prostate.
- The Gleason score is 7, and the PSA level is less than 20.
Stage IIC
- The cancer hasnât spread beyond the prostate.
- The doctor may or may not be able to feel the tumor during a DRE or see it on an imaging test.
- The tumor can be in one or both lobes of the prostate.
- The Gleason score is 7 or 8, and the PSA level is less than 20.
- The cancer cells appear more abnormal than in stage IIB.
Stage IIIA
Which Approach Is Best For Biopsy Gleason Score 910 Prostate Cancer
A recent study in JAMA Oncology compared survival for various multi-modality approaches for treating aggressive prostate cancer.
Treatment with radical prostatectomy plus adjuvant external beam radiotherapy , androgen deprivation therapy , or both provides equivalent survival outcomes as EBRT, brachytherapy, and ADT in men with Gleason score 910 prostate cancer, according to a new study in JAMA Oncology.
It makes logical sense that in these very aggressive prostate cancers, you need a multi-modality approach, said study author Anthony V. DAmico, MD, PhD, who is chief of the Division of Genitourinary Radiation Oncology and an institute physician at Dana-Farber Cancer Institute at Brigham and Womens Hospital in Boston.
Researchers evaluated a total of 639 men with clinical T1T4, N0M0 biopsy Gleason score 910 prostate cancer. In this cohort, 80 were consecutively treated with MaxRT between February 6, 1992 and April 26, 2013. A total of 559 men were consecutively treated with RP and pelvic lymph node dissection. Among the 559 men managed with RP and pelvic lymph node dissection, 88 received adjuvant EBRT , 49 received ADT , and 50 received both . The median follow-up was 5.51 years among 80 men treated with MaxRT, and 4.78 years among 559 men treated with RP-containing treatments.

Survival By Tumor Grade
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:

Can The Gleason Score On My Biopsy Really Tell What The Cancer Grade Is In The Entire Prostate
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.
Should I Get A Second Opinion About My Gleason Score And Prostate Cancer Diagnosis
It is always the patient’s right to obtain a second opinion about a cancer diagnosis or any other medical condition. Talking to a radiation oncologist will allow them to review your pathology report and request any other tests they may need to make sure you have the right information to make a decision about your treatment plan.
If you would like one of our radiation oncologists to review your pathology report, you only need to sign a release so we can have your biopsy material sent to us. We can then determine the Gleason score our team sees. Most of the time, the Gleason score we determine is the same, but not always. Because the Gleason score is the most important issue about your particular cancer, we want it to be as accurate as possible.
It’s critical to personally research prostate cancer treatment options to make an informed decision that is best for you and your family. And, with few exceptions, your first treatment gives you the best chance for success. If your urologist has told you that you have a Gleason score of 6 – 10, or you would like a second opinion, request an appointment for a consultation.

Understanding Prostate Cancers Progression
To determine the appropriate treatment, doctors need to know how far the cancer has progressed, or its stage. A pathologist, the doctor trained in analyzing cells taken during a prostate biopsy, will provide two starting pointsthe cancers grade and Gleason score.
- Cancer grade: When the pathologist looks at prostate cancer cells, the most common type of cells will get a grade of 3 to 5. The area of cancer cells in the prostate will also be graded. The higher the grade, the more abnormal the cells.
- Gleason score: The two grades will be added together to get a Gleason score. This score tells doctors how likely the cancer is to grow and spread.
After a biopsy confirms prostate cancer, the patient may undergo additional tests to see whether it has spread through the blood or lymph nodes to other parts of the body. These tests are usually imaging studies and may include a bone scan, positron emission tomography scan or computed tomography scan.

The Updated Gleason Grading System Is Misleading For Patients And Physicians
The Gleason grading system, based on five architectural patterns of a tumor, has evolved over time.4 For practical purposes, Gleason patterns 1 and 2, or scores 2 to 4 noted in the classic system, are not diagnosed on needle biopsies because of poor correlation with radical prostatectomy grade and poor reproducibility among expert pathologists.5 The Gleason system has been modified based on a 2005 consensus conference,4 whereby lesions previously referred to as Gleason scores 2 to 4 in the classic system are now assigned a higher grade in the modified system however, those previously graded as Gleason score 6 in the classic system are often graded as Gleason score 7 tumors in the modified system. Although this modification of grading could improve the prognosis of some men who have cancer-specific outcomes intermediate between the modified Gleason score 6 and the classical Gleason score 3 + 4 cancers,6 the larger effect of the 2005 modification has been to improve the perceived cancer-specific survival by 26% through the Will Rogers phenomenon.7

Prostate Biopsy Collaborative Group Risk Calculator
The Prostate Biopsy Collaborative Group Risk Calculator is similar in nature to the PCTP in that it looks at a variety of factors to determine candidacy for a biopsy. Thus, it can help to reduce unnecessary biopsies. However, this and the PCTP calculators have shown disparities in results across different race groups.
Prostate cancer treatment is approached with such consideration because the 5-year relative survival rate of all stages combined is high at 98%. Therefore, experts consider some treatment options unnecessary for survivability.
Monitoring And Treatment Decisions
In the past, men with prostate cancerregardless of whether it was aggressive or notwere almost always treated right away with a targeted therapy like surgery or radiation. However, in recent years, experts have revisited this one-size-fits-all approach to prostate cancer.
Experts now understand that low-risk prostate cancerlike Gleason 6 tumorsmay not need treatment right away. In fact, major medical associations, including the American Urological Association and the Society for Urologic Oncology, now recommend the use of active surveillance for low-risk prostate cancer.

Tertiary Grade On Needle Core Biopsy
In contrast to the original Gleason grading system, it is now recommended that on a needle core biopsy both the most common and highest grade are added together for the Gleason score . For example, if there is 60 % Gleason pattern 3, 35 % Gleason pattern 4, and 5 % Gleason pattern 5, the Gleason score would be 3+5=8. Needle core biopsy is an imperfect, non-targeted, random sampling of the prostate gland. Thus any amount of high-grade tumor sampled on needle biopsy most likely indicates a more significant amount of high-grade tumor within the prostate. In all specimens, in the setting of high-grade cancer, one should not report a lower grade if it occupies less than 5 % of the total tumor. For example, if there is 98 % Gleason pattern 4 and 2 % Gleason pattern 3, the Gleason score would be reported as 4+4=8 .
