Have you heard of a Gleason Score for prostate cancer? Let's talk about it!

When the doctor tells you that you have prostate cancer, you must feel a lot of stress and anxiety, right? At that time, you hear about new medical tests and complicated terms. You may hear, or you may have already heard, one word is the 'Gleason Score'. So, when you hear this, you may be afraid, "What is this new thing?" That's why, today we will talk about what this Gleason Score is, and what it really says about your condition, in a simple way that you can understand.

Do you know what a Gleason Score is?

Simply put, if you have prostate cancer, the Gleason Score is a way of assessing the nature of the cancer – what it looks like, how fast it might spread, how aggressive it might be, etc. It's like grading a test in school, but it's a little more scientific and complicated.

This is something that pathologists ( specialists who examine tissue and diagnose diseases) do by looking at a sample of your prostate tissue (a small piece taken during a biopsy) under a microscope to determine what the cancer cells look like. This scoring system helps doctors plan the best treatment for you and make a prediction about your prognosis after treatment.

How is the Gleason Score calculated?

Okay, now let's look at how this Gleason Score is made. As I mentioned before, pathologists do this important work. They look at tissue samples from your prostate very carefully under a microscope. If you have prostate cancer, it means that some of the cells in your prostate have changed from normal, healthy cells to become cancer cells .

Imagine, in the early stages, these cancer cells may look like healthy cells. Just disguised. But over time, as the cancer progresses, the appearance of these cancer cells becomes very different and abnormal from healthy cells. That difference, that abnormality, is what pathologists grade.

Grading System

They give each tissue sample a score from 1 to 5 based on the nature of the cancer cells, that is, how much they differ from healthy cells. This is called the cancer grade .

• Grade 1: The cancer cells look very much like healthy, normal cells. That is, there is very little difference. They are arranged in an orderly manner.
• Grades 2-4: The cancer cells in the tissue appear to be slightly different from healthy cells and appear to be more irregular. As the grade increases, this difference and irregularity become more pronounced.
• Grade 5: The cancer cells are very abnormal, looking very disorganized and out of place with healthy cells. These are the most aggressive cells.

Now, prostate cancer can have the same cells in the same area, or it can have different grades of cells in different areas. So, what the pathologist does is pick the main area where the cancer has spread the most and assign it a grade (between 1-5). Then, they pick the second most spread area (which has a different pattern) and assign it a grade. The two main grades are then added together. That sum is your Gleason Score.

For example, let's say the most abundant cancer is grade 3. The next most abundant is grade 4. Then the Gleason score would be 3 + 4 = 7. Another example, if the dominant pattern is grade 4 and the secondary pattern is grade 3, the Gleason score would be 4 + 3 = 7. So even though 3+4 and 4+3 are both 7, doctors sometimes consider the order of these patterns (higher grade first).

Generally, if this combined Gleason score is 6 or higher, it is considered cancer.

Is there such a thing as a normal Gleason Score?

Now you may be wondering, is there a "normal" Gleason Score? Actually, there is no such thing as a "normal" Gleason Score, like when we check our blood sugar levels for diabetes, or when we look at our prostate cancer PSA levels and say, "Here's the normal range." Instead, doctors divide the Gleason Score into three categories and use them to understand the behavior of the cancer:

• Gleason score 6: In this case, the cancer cells look very similar to healthy cells. We call this a ``well differentiated'' cancer. Simply put, the cells are still like "good kids," trying to resemble normal cells. These are usually considered slow-growing, less aggressive cancers.
• Gleason score 7: In this case, the cancer cells look somewhat like healthy cells, but there is some irregularity. We call this a ``moderately differentiated'' cancer. This is like the middle ground. There can be a slight difference between 3+4=7 and 4+3=7. The 4+3 pattern is sometimes considered a slightly more concerning condition than the 3+4 pattern.
• Gleason score 8, 9 or 10: The cancer cells are very different from healthy cells. They are very irregular and have no resemblance to each other. We call this a 'poorly differentiated' or 'undifferentiated' cancer. These cells are a little more aggressive and tend to grow and spread more quickly.

What is a good Gleason Score for prostate cancer?

It's hard to immediately label a Gleason score as "good" or "bad." However, knowing your Gleason score can give your doctor an important idea of ​​how quickly your prostate cancer is growing and how likely it is to metastasize to other parts of the body. The Gleason score ranges from 6 to 10.

Generally, if the Gleason score is low (for example, 6), it is considered a 'low-grade cancer.' These types of cancers grow slowly and are less likely to spread to other areas.

If the Gleason score is high (for example, 8, 9, 10), it is considered a 'high-grade cancer.' These types of cancers are more likely to grow and spread quickly.

But, it's important to remember this: Your Gleason score is just one piece of information that doctors use to plan your treatment and give you a prognosis. That means that Gleason score alone is not the answer. It's just one piece of a bigger picture.

Is the Gleason Score the only thing that matters?

No, not at all. As I said before, your Gleason Score is just one piece of the puzzle. Doctors take many other factors into account to understand your complete condition and choose the best treatment for you.

For example, when you had your biopsy, your doctor may have taken several samples, called cores, from your prostate. So,

• How many of those cores (pieces of tissue) contained cancer cells?
• What percentage of each `(core)` was filled with cancer cells?

I'm also looking at things like that.

In addition, these things are also very important:

• Your blood `(PSA)` level. (PSA - Prostate-Specific Antigen) (a special blood test).
• The results of the Digital Rectal Exam (DRE) performed by the doctor (that is, the way the gland is felt in the hand).
• Information from specialized imaging tests such as ultrasound scans, MRI scans, or PET scans can help determine the size and spread of the cancer.
• Whether the cancer is on both sides of the prostate gland.
• Prostate cancer is said to have spread (metastasized) to other parts of the body, for example, the bones.
• Your age and overall health.

Putting all of this together, like completing a big puzzle, is how your doctor will decide what the best treatment is for you, based on your condition. So, don't worry unnecessarily about the Gleason score, okay?

The most important thing you need to keep in mind (Take-Home Message)

Okay, so here's the most important thing to remember from what we've talked about. The Gleason Score is an important tool that categorizes prostate cancer and gives you an idea of ​​how aggressive it is. Your doctor uses it to plan the best treatment for you. The Gleason Score can range from 6 (low-grade, less aggressive cancer) to 10 (high-grade, more aggressive cancer). Cancers with a low Gleason Score are usually slow-growing and have a low risk of spreading.

But these numbers alone don't tell the whole story about your prostate cancer. That story starts with your treatment plan and understanding what you can expect from those treatments, as well as the pros and cons. Your Gleason score and other test results are like a guide to help you on your journey to recovery.

If you ever have any questions or concerns about your Gleason Score, any other test results, or your medical condition, don't hesitate to ask your doctor. He or she will be happy to explain what those numbers and words mean and answer any questions you may have. Remember, you are not alone on this journey. There are doctors and a healthcare team there to help you and take care of you.
