Types of staging There are two types of staging for prostate cancer. Clinical staging: This is based on the results of pre-surgery procedures such as a prostate-specific antigen (PSA) test, a digital rectal exam (DRE), a Gleason score (a grade based on how cancer cells behave on a micro level) and imaging tests. A doctor uses these results to determine the stage of the cancer and decide whether to recommend further diagnostic exams, such as a magnetic resonance imaging (MRI) scan. Pathological staging: This type of staging is based on information uncovered after prostate surgery. The prostate tissue is examined to get a more detailed, and sometimes more accurate, stage of the disease. Understanding prostate cancer’s 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 points—the cancer’s 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 (PET) scan or computed tomography (CT) scan. Prostate cancer treatment: The care you need is one call away Your multidisciplinary team will work with you to develop a personalized plan to treat your prostate cancer in a way that fits your individual needs and goals. DISCOVER THE CTCA DIFFERENCE Stages of prostate cancer Doctors use the results of all these tests to help determine the stage of the prostate cancer, or how far it has progressed. Widely used staging criteria is based on the TNM system developed by the American Joint Committee on Cancer. TNM staging system The three key components of the TNM system, include: T (tumor) describes the tumor’s size, location and how deep it has grown into the tissue.

M (metastasis) refers to whether the cancer cells have spread to distant organs or tissue. The stage of cancer will help doctor and patient determine the most appropriate options for treatment. Prostate cancer stages range from 1 through 4. Stage 1 prostate cancer Cancer is on one side of the prostate. Cancers usually grow slowly. PSA level may not be high and the cancer may not be felt during a DRE. There is no lymph node involvement nor metastasis. Some cancers that are felt during a DRE may still be classified as stage 1 if the Gleason score is 6 or less and the PSA is lower than 10. Stage 2 prostate cancer means the cancer remains confined to the prostate gland. It has three substages: Stage 2A: The cancer is on one or both sides of the prostate gland. The PSA blood test level is between 10 and 19. The Gleason score is 6 or less. Stage 2B: The cancer is on one or both sides. The PSA is lower than 20. The Gleason score is 7. Stage 2C: The cancer is on one or both sides. The PSA is lower than 20. The Gleason score is 7 to 8. means the cancer remains confined to the prostate gland. It has three substages: Stage 3 prostate cancer means the cancer is locally advanced. The tumor has progressed and is more likely to grow and spread, with both the Gleason score and the PSA being high. This stage also has three substages: Stage 3A: The cancer is on one or both sides of the prostate. The PSA is 20 or higher. The Gleason score may be as high as 8. Stage 3B: The cancer has spread outside the prostate gland to nearby tissues but not to the lymph nodes. The PSA may be any level. The Gleason score may be up to 8. Stage 3C: This stage is similar to 3B, but the cancer may not be growing beyond the prostate. The Gleason score is 9 or 10. means the cancer is locally advanced. The tumor has progressed and is more likely to grow and spread, with both the Gleason score and the PSA being high. This stage also has three substages: Stage 4 prostate cancer means the cancer has spread to lymph nodes or to other parts of the body. It is further divided into two substages: Stage 4A: The cancer has spread to nearby lymph nodes but may or may not have spread to nearby tissues. Stage 4B: The cancer has spread to another area of the body, such as the bones or distant lymph nodes.
