Staging Of Prostate Cancer
The stage of a cancer describes its size and how far it has spread. The results of your tests help your doctors decide on the stage and plan your treatment.
We understand that waiting to know the stage and grade of your cancer can be a worrying time. We’re here if you need someone to talk to. You can:

Stages Of Prostate Cancer

Any T, any N, M1 Any Grade Group Any PSA |
The cancer might or might not be growing into tissues near the prostate and might or might not have spread to nearby lymph nodes . It has spread to other parts of the body, such as distant lymph nodes, bones, or other organs . The Grade Group can be any value, and the PSA can be any value. |
Prostate cancer staging can be complex. If you have any questions about your stage, please ask someone on your cancer care team to explain it to you in a way you understand.
While the stage of a prostate cancer can help give an idea of how serious the cancer is likely to be, doctors are now looking for other ways to tell how likely a prostate cancer is to grow and spread, which might also help determine a mans best treatment options.
Immediate Versus Deferred Hormonal Therapy
Refer to the Treatment Option Overview for Prostate Cancer section for information on the use of immediate hormonal therapy plus radiation in the setting of locally recurrent prostate cancer after radical prostatectomy.
PSA is often used to monitor patients after initial therapy with curative intent, and elevated or rising PSA is a common trigger for additional therapy even in asymptomatic men. Despite how common the situation is, it is not clear whether additional treatments given because of rising PSA in asymptomatic men with prostate cancer increase OS. The quality of evidence is limited.

What Tests Check For Prostate Cancer
Common tests to check for prostate cancer include:
- Digital rectal exam: Your doctor inserts a finger into your rectum and touches your prostate gland. The doctor feels the shape of the prostate gland and checks for any hard spots.
- PSA blood test: This blood test tells how much PSA is in your blood. Many men with prostate cancer have PSA levels that are higher than normal or that have gotten higher over time.
- A high PSA level does not always mean a man has prostate cancer. As men get older, their prostate gland may grow larger over time. This growth, and other health conditions, can cause a high PSA level in men who do not have prostate cancer.
If the test results are not normal, your doctor may recommend more tests, such as a biopsy. During a biopsy, the doctor uses a needle to take out a tiny piece or pieces of the prostate gland. An ultrasound probe may be used to guide the needle. Another doctor called a pathologist looks at the tissue under a microscope to check for cancer cells.
Note
What Is The Gleason Grading System
Your Gleason score isn’t a separate test. It’s a number based on the results of your biopsy. You usually get it when you’re first diagnosed with prostate cancer.
The doctor uses the numbers 1 to 5 to grade the most common and second most common patterns of cells found in a tissue sample:
- Grade 1. The cells look very much like normal prostate cells.
- Grades 2-4. Cells that score lower look closest to normal and represent a less aggressive cancer. Those that score higher look the furthest from normal and will probably grow faster.
- Grade 5. Most cells look very different from normal.
The two grades added together are your Gleason score. Cancers will score 6 or more. A score of 7 means the cancer is intermediate, and a higher score means the cancer is more likely to grow and spread.
Your doctor will use this combined score along with the results of your PSA blood test and digital rectal exam to see how advanced your prostate cancer is. They’ll use this information to suggest the best treatment for you.

Prostate Cancer: Stages Grades And Treatment
Cancer stage refers to the size of the tumor and whether or not it has spread to other parts of the body prostate cancer is staged using the TNM system. Cancer grade refers to how quickly the cancer cells will grow and spread prostate cancer is graded using the Gleason score. Treatment of prostate cancer is based on a combination of age, life expectancy, and personal preferences, in addition to cancer grade and stage. In general, the higher the grade or stage, the more likely it is that the cancer will spread.

Localized Prostate Cancer: Treatment Options
STEPHEN BRAWLEY, MD, PhD RAVINDER MOHAN, MD, PhD and CHRISTOPHER D. NEIN, MD, Eastern Virginia Medical School, Portsmouth, Virginia
Am Fam Physician. 2018 Jun 15 97:798-805.
Patient information: See related handout on prostate cancer.
Prostate cancer is the third most common cause of cancer-related death in U.S. men, with an estimated 161,000 cases and 26,700 deaths in 2017.1,2 In the United States, prostate cancer will be diagnosed in one out of seven men in his lifetime. However, most cases are localized, and only one in 39 men will die from the disease.3 Prostate cancer incidence and mortality are higher in black men.3
WHAT IS NEW ON THIS TOPIC
The 2014 International Society of Urological Pathology consensus conference established the Gleason grade group system. Gleason grade group 1 is associated with lower risk.
A randomized controlled trial of 1,643 men with clinically localized prostate cancer found no difference in prostate cancerspecific mortality among active surveillance, radical prostatectomy, and external beam radiation therapy over 10 years. Surgery and radiation therapy were associated with lower incidences of disease progression than active surveillance.
SORT: KEY RECOMMENDATIONS FOR PRACTICE
Recommended treatment options for localized prostate cancer, including active surveillance, are based on clinical stage, pathologic grade, prostate-specific antigen level, and comorbidity-adjusted life expectancy.

What Are Prostate Cancer Treatment Side Effects
Some prostate cancer treatments can affect the bladder, erectile nerves and sphincter muscle, which controls urination. Potential problems include:
- Incontinence: Some men experience urinary incontinence. You may leak urine when you cough or laugh, or you may feel an urgent need to use the bathroom even when your bladder isnt full. This problem can improve over the first six to 12 months without treatment.
- Erectile dysfunction : Surgery, radiation and other treatments can damage the erectile nerves and affect your ability to get or maintain an erection. Some men regain erectile function within a year or two . In the meantime, medications like sildenafil or tadalafil can help by increasing blood flow to the penis.
- Infertility: Treatments can affect your ability to produce or ejaculate sperm, resulting in male infertility. If you think you might want children in the future, you can preserve sperm in a sperm bank before you start treatments. After treatments, you may undergo sperm extraction. This procedure involves removing sperm directly from testicular tissue and implanting it into a womans uterus.

How Prostate Cancer Spreads
- The cells escape into the bloodstream, initially by invading small blood vessels around the tumor, then traveling to larger blood vessels that enable the cells to circulate around the body .
- The cells are filtered through the bodys lymph system although some are captured in lymph nodes, others may travel elsewhere in the body.
- The cells migrate along the length of a nerve, escaping from the prostate into adjacent soft tissue .

Stage 2 Prostate Cancer
In stage 2, the tumor is still confined to your prostate and hasnt spread to lymph nodes or other parts of your body. A doctor may or may not be able to feel the tumor during a prostate exam, and it may appear on ultrasound imaging. The survival rate is still near 100 percent.
The PSA score for stage 2 is less than 20 ng/mL.
Stage 2 cancer is further divided into three phases depending on the grade group and Gleason scores:
- Grade group: 1
- Gleason score: 6 or less

Gleason Score 7 Life Expectancy
Gleason Score 7 Life Expectancy. Cancer symptoms gleason score 7 life expectancy. 7 percentage of positive biopsies less than 34%.
In this population based cohort we determined prostate cancer outcomes at different gleason scores, particularly the different gleason 7 patterns. Patients with a given gleason score and a projected life expectancy of at least 10 years may be at similar risk of dying from prostate cancer as younger patients. Men 40 to 64 years old who were diagnosed with prostate cancer between 1993 and 1996 in king county, washington comprised the cohort.

Treatment Options Under Clinical Evaluation
Treatment options under clinical evaluation for patients with prostate cancer include the following:
Cryosurgery
Cryosurgery, or cryotherapy, is under evaluation for the treatment of localized prostate cancer. It is a surgical technique that involves destruction of prostate cancer cells by intermittent freezing of the prostate with cryoprobes, followed by thawing. There is limited evidence regarding its efficacy and safety compared with standard prostatectomy and radiation therapy, and the technique is evolving in an attempt to reduce local toxicity and normal tissue damage. The quality of evidence on efficacy is low, currently limited to case series of relatively small size, short follow-up, and surrogate outcomes of efficacy.
Serious toxic effects associated with cryosurgery include bladder outlet injury, urinary incontinence, sexual impotence, and rectal injury. Impotence is common, ranging from about 47% to 100%.
The frequency of other side effects and the probability of cancer control at 5 years follow-up have varied among reporting centers, and series are small compared with surgery and radiation therapy. Other major complications include urethral sloughing, urinary fistula or stricture, and bladder neck obstruction.
Proton-beam therapy
Vascular-targeted photodynamic therapy using a photosensitizing agent has been tested in men with low-risk prostate cancer.
Neoadjuvant hormonal therapy
The role of neoadjuvant hormonal therapy is not established.

What Is Prostate Cancer
The prostate is a gland found only in males that lies just below the bladder and in front of the rectum. Prostates in younger men are about the size of walnuts but tend to become larger as they age. It serves two main functions in the body. The first is to secrete prostate fluid and the second is to help move the seminal fluid into the urethra during ejaculation with the use of muscles.
Prostate cancer occurs when the cells in the prostate gland begin to grow rapidly and out of control. Usually, it starts out growing slowly and stays within the prostate.
There are 5 types of prostate cancers:
- Adenocarcinomas
- Transitional cell carcinomas
- Sarcomas
Chances are high that when you are diagnosed with prostate cancer, it is adenocarcinoma, which starts in the gland cells.
The other 4 types of prostate cancers are less common. Like all cancers, prostate cancer is graded to determine how aggressive and rapidly it is growing. No matter the type of cancer, all patients diagnosed are staged. This means assigning a grade that defines how aggressive the cancer is. For staging prostate cancer, the Gleason Score is the method used.

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.

What Is A Grade Group
In 2014, the International Society of Urological Pathology released supplementary guidance and a revised prostate cancer grading system, called the Grade Groups.
The Grade Group system is simpler, with just five grades, 1 through 5.
*Risk Groups are defined by the Grade Group of the cancer and other measures, including PSA, clinical tumor stage , PSA density, and number of positive biopsy cores.
Many hospitals report both the Gleason score and the Grade Group, but there may be hospitals that still report only the old Gleason system.
Initial Treatment Of Prostate Cancer By Stage
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 havent spread , doctors also use risk groups to help determine treatment options. Risk groups range from very low risk to very high risk, with lower risk group cancers 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 taken into account 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.

What Causes Prostate Cancer
Experts arent sure why some cells in the prostate gland become cancerous . Genetics appear to play a role. For example:
- Youre two to three times more likely to get prostate cancer if your father, brother or son has the disease.
- Inherited mutated breast cancer genes and other gene mutations contribute to a small number of prostate cancers.

Prostate Cancer Risk Groups
In addition to stage, doctors may use other prognostic factors to help plan the best treatment and predict how successful treatment will be. Examples of these include the National Comprehensive Cancer Network risk group categories and the Cancer of the Prostate Risk Assessment risk score from University of California, San Francisco.
Information about the cancers stage and other prognostic factors will help the doctor recommend a specific treatment plan. The next section in this guide is Types of Treatment. Use the menu to choose a different section to read in this guide.
