Prostatic adenocarcinoma is the most common type of prostate cancer. Understanding your Gleason score is crucial for determining the aggressiveness of your cancer and guiding treatment decisions. This article explains what the Gleason score is, how it's determined, and what the different scores mean.

What is the Gleason Score?

The Gleason score is a grading system used to assess the aggressiveness of prostate cancer. It's based on how much the cancerous cells resemble normal prostate cells under a microscope. The more the cancer cells deviate from normal cells, the higher the Gleason score and the more aggressive the cancer is considered.

How is the Gleason Score Determined?

A pathologist examines a tissue sample (biopsy) from the prostate. They identify the two most common patterns of cancerous cells. Each pattern is assigned a grade from 1 to 5, with 1 representing well-differentiated cells (closely resembling normal cells) and 5 representing poorly differentiated cells (looking very different from normal cells). These two grades are added together to arrive at the final Gleason score. For example, a 3+3 Gleason score means the two most common patterns were grade 3 and grade 3.

Understanding Gleason Score Ranges

Gleason scores range from 2 to 10. The higher the score, the more aggressive the cancer is likely to be. This translates to a higher risk of the cancer spreading and potentially recurring after treatment.

Gleason Score 2-6: Generally indicates a low-grade, less aggressive cancer.
Gleason Score 7: This is considered an intermediate-grade cancer and can be further categorized as 7 (3+4) or 7 (4+3). 7 (3+4) is considered less aggressive than 7 (4+3).
Gleason Score 8-10: These scores indicate a high-grade, very aggressive cancer that's more likely to spread and recur.

Important Note: The Gleason score is just one factor considered when determining treatment. Other factors, such as the stage of the cancer (how far it has spread), your age and overall health, and your personal preferences, also play a crucial role in treatment planning.

What Does My Gleason Score Mean for Me?

Your Gleason score, combined with other factors, will help your doctor determine the best course of treatment for you. Treatment options for prostate cancer range from active surveillance (close monitoring) to surgery, radiation therapy, hormone therapy, and chemotherapy. Your doctor will discuss the risks and benefits of each option, taking your individual circumstances into account.

Gleason Score and Prognosis

A higher Gleason score is generally associated with a less favorable prognosis. This means there's a greater chance the cancer will spread and recur. However, even with a high Gleason score, many men with prostate cancer can be successfully treated, and it's vital to maintain a positive outlook and actively participate in your treatment plan.

Questions to Ask Your Doctor

What is my specific Gleason score and what does it mean in my case?
What other factors are being considered in my treatment plan?
What are my treatment options, and what are the risks and benefits of each?
What is my prognosis with and without treatment?
What are the long-term side effects of potential treatments?
What kind of follow-up care will I need?

Receiving a prostate cancer diagnosis can be overwhelming. Remember that you're not alone. It's important to talk openly with your doctor, family, and friends. Seeking support from cancer support groups can also be beneficial.
