Understanding Your Risk Level

When Newly Diagnosed

 

Treatment options for men newly diagnosed with prostate cancer are based on their risk level which is determined by:

Understanding Your Risk Levels

Risk levels for patients initially diagnosed with prostate cancer before any treatment

Doctors use disease features including (but not limited to) those listed below to determine prostate cancer risk group.

Very Low

Patients with an initial diagnosis of PSA less than 10, Gleason 6/Grade Group 1, and less than 3 biopsy cores positive for cancer. Cancer found by needle biopsy and cannot be felt during exam. (Stage 1)

Low

Patients with an initial diagnosis of PSA less than 10, Gleason 6/Grade Group 1. Cancer involves one half of one side of the prostate or less. (Stage 1)

Intermediate Favorable

Patients with an initial diagnosis that includes one of the following: Gleason 7/Grade Group 2, PSA 10-20, or cancer involves more than one-half of one side of the prostate or involves both sides of the prostate. (Stage 1 or 2)

Intermediate Unfavorable

Patients with an initial diagnosis of Gleason 7/Grade Group 3 or that includes 2 or 3 of the following: Gleason 7/Grade Group 2, PSA 10-20, cancer involves more than one-half of one side of the prostate or both sides of the prostate. (Stage 1 or 2)

High

Patients with an initial diagnosis that includes one of the following: PSA more than 20, Gleason 8-9/Grade Group 4-5, tumor has spread a little outside the prostate. (Stage 2 or 3)

Very High

Patients with an initial diagnosis that includes one of the following: Gleason 9-10/Grade Group 5, tumor has spread to nearby organs. (Stage 3)

Regional

Patients with an initial diagnosis of cancer spread to nearby lymph nodes – Regional; Any PSA, Gleason/Grade Group. (Stage 4A)

Metastatic

 Patients with an initial diagnosis of cancer spread to distant parts of the body – metastatic; Any PSA, Gleason/Grade Group. (Stage 4B)

PSA Number

The PSA number is a measure of how much PSA is in the blood stream an indication of the cancer (volume) a patient has when he is diagnosed. The PSA number can be low, in the single digits, or in the hundreds, and sometimes more than a thousand.

Biopsy Results

A biopsy needle is used to take tissue (usually 12 cores) from the prostate gland which is examined under a microscope to see if cancer is present. The tissue will also be used to determine the Gleason score if cancer is present.

Gleason Score

The Gleason score is a measure of how aggressive the cancer is.

6 or less – The cancer is likely to grow and spread very slowly; low grade.

7 – The cancer is likely to grow and spread at a modest pace; favorable intermediate with few aggressive cancer cells; unfavorable intermediate with more aggressive cells.

8, 9 or 10 – Cancer is likely to grow and spread fast; high grade.

Grade Groups

Grade groups are based on the Gleason score and intended to be a more simplified measure of cancer aggressiveness.

1 = Gleason score 6 or less

2 = Gleason score 7 favorable

3 = Gleason score 7 unfavorable

4 = Gleason score 8

5 = Gleason score 9 or 10

Cancer Stage

Imaging and other tests are used to determine where the cancer is within the patient’s body.
 

  • Localized (stage 1) – Cancer is located within the prostate gland only in one lobe.
  • Locally Advanced (Stage 2) – Cancer is still within the prostate gland but in both lobes and maybe spread to seminal vesicles.
  • Regional (Stage 3) – Cancer has spread beyond the prostate to nearby lymph nodes and possibly to other nearby tissues.
  • Metastatic (Stage 4) – Cancer has spread beyond the prostate to distant parts of the body such as bone and other organs.
