Who Is At Risk For Advanced Prostate Cancer
The exact cause of prostate cancer isnt clear. Your risk of developing this particular cancer increases after you reach age 50.
Certain groups are more likely to develop aggressive forms of prostate cancer, including African-American men and men who carry certain inherited genetic mutations such as BRCA1, BRCA2, and HOXB13.
Most men with prostate cancer dont always have a family history of the disease. But having a father or brother with prostate cancer more than doubles your risk.

What Does It Mean To Have A Gleason Score Of 6 Or 7 Or 8
The lowest Gleason Score of a cancer found on a prostate biopsy is 6. These cancers may be called well-differentiated or low-grade and are likely to be less aggressive they tend to grow and spread slowly.
Cancers with Gleason Scores of 8 to 10 may be called poorly differentiated or high grade. These cancers tend to be aggressive, meaning they are likely to grow and spread more quickly.
Cancers with a Gleason Score of 7 may be called moderately differentiated or intermediate grade. The rate at which they grow and spread tends to be in between the other 2.

Survival By Disease Recurrence
If a man develops an elevated PSA level after cancer surgery, then the disease is viewed as recurrent.
The number of lymph nodes at the time of prostatectomy can influence the risk of recurrence. One study suggests the removal of a large number of nodes is associated with an improvement in odds of recurrence, but this doesnt appear to impact overall survival.
But disease recurrence doesnt always influence survival times. If a recurrence does occur, the 15-year survival rate at the time of diagnosis may be as high as 94% in those with low-risk recurrence.
The main factors influencing survival rates are:
- The Gleason score
- The PSA doubling time
- Whether the recurrence occurred within three years or after three years
A recurrence that occurs within three years reduces survival rates by anywhere from 15 to 20%and even more, if the doubling time is short.

Bladder And Urinary Troubles
A prostate tumor that has grown significantly in size may start to press on your bladder and urethra. The urethra is the passage the carries urine from your bladder out of your body. If the tumor is pressing on your urethra, you might have trouble passing urine.
One of the common areas for prostate cancer to spread to is the bladder, because the two organs are close. This can cause additional problems with urination and bladder function.
Some symptoms your bladder and urethra are being affected by cancer include:
- urinating more frequently
- getting up in the middle of the night to pee
- having blood in your urine or semen
- feeling like you have to urinate often and not actually passing anything
Its not as common, but prostate cancer can also spread to your bowel. The cancer first spreads to the rectum, which is the part of your bowel closest to the prostate gland.
Symptoms of cancer thats spread to the bowels include:
- stomach pain

Stage Iv Prostate Cancer Prognosis
Prostate cancers detected at the distant stage have an average five-year survival rate of 28 percent, which is much lower than local and regional cancers of the prostate. This average survival rate represents stage IV prostate cancers that have metastasized beyond nearby areas to lymph nodes, organs or bones in other parts of the body.
How We Treat Prostate Cancer
The prognosis for metastatic prostate cancer can be discouraging, but some treatment centerslike the Johns Hopkins Precision Medicine Center of Excellence for Prostate Cancerspecialize in innovative, individualized therapy with the potential to improve outcomes.
The Tnm System For Prostate Cancer Stages
As they do for most cancers, doctors use the TNM system to describe prostate cancer stages. The system uses three different aspects of tumor growth and spread:
- Tumor. Whatâs the size of the main area of prostate cancer?
- Nodes. Has it spread to any lymph nodes? If so, how far and how many?
- Metastasis. How far has the prostate cancer spread?

The Most Common Symptoms Of Stage 3 Mesothelioma Include:
- Shortness of breath
- Fluid buildup
- Weight loss
As the tumors continue to grow and spread throughout the chest, symptoms will become more problematic. Stage 3 symptoms vary from patient to patient depending on where the cancer is spreading and if the tumor mass damages vital organs. Some patients may experience referred pain felt in the neck, back or shoulders.
A tumor invading the chest wall may cause increased chest pain, while tumors forming around the lung may lead to increased breathing difficulties. Pleural mesothelioma tumors also cause increased pleural fluid, which puts pressure on the lungs. Symptoms and characteristics of stage 3 mesothelioma vary based primarily on cancer type.

Grade: How Aggressive Is The Cancer
The pathology team will take a biopsy sample and prepare it with chemicals, then make extremely fine slices of the tissue to examine under the microscope. If prostate cancer is found when looking at biopsied tissue under a microscope, the pathologist assigns a grade to the cancer. There are 2 grading systems currently in use, which can be confusing for patients.
The classical grading system for prostate cancer is called the Gleason score, which ranges from 6 to 10 .
In 2014, the World Health Organization reorganized the Gleason score with the simpler Grade Group system, ranging from 1 to 5 .
Many medical centers report both the Gleason score and the Grade Group, but there may be some that still only report the old Gleason system.
Both systems attempt to communicate a variety of factors in a way that allows the medical team to communicate and compare cases and strategize treatments.

Where Does Prostate Cancer Usually Spread First
If prostate cancer spreads to other parts of the body, it almost always goes to the bones first. These areas of cancer spread can cause pain and weak bones that might break. Medicines that can help strengthen the bones and lower the chance of fracture are bisphosphonates and denosumab.

Stage 1 Prostate Cancer
Stage 1 is the least advanced form of prostate cancer. Cancer in this stage is small and hasnt spread past the prostate gland. Its characterized by a PSA of less than 10 ng/mL, a grade group score of 1, and a Gleason score of 6.
Stage 1 prostate cancer has a 5-year survival rate of nearly 100 percent.

Pharmacologic Agents In Prostate Cancer
Gonadotropin-releasing hormone analogues suppress ovarian and testicular steroidogenesis by decreasing luteinizing hormone and follicle stimulating hormone levels, whereas GnRH antagonists lower serum testosterone levels by suppressing LH and FSH.
Bisphosphonates are analogues of pyrophosphate that act by binding to hydroxyapatite in bone matrix, thereby inhibiting the dissolution of crystals. These agents prevent osteoclast attachment to the bone matrix and osteoclast recruitment and viability.
Antiandrogens are used as combination agents to treat prostate cancer. Antifungal agents produce a response similar to that of antiandrogens. These drugs inhibit various cytochrome P-450 enzymes, including 11-beta-hydroxylase and 17-alpha-hydroxylase, which in turn inhibit steroid synthesis. The antiandrogen abiraterone is a 17 alpha-hydroxylase/C17, 20-lyase inhibitor that was approved by the US Food and Drug Administration in 2011 for use in combination with prednisone for treatment of metastatic castration-resistant prostate cancer in patients who received prior chemotherapy containing docetaxel.
An ultramicronized abiraterone tablet was approved in May 2018 for CRPC in combination with methylprednisolone. The ultramicronized formulation may be administered with or without food, whereas, the original tablet formulation must be administered 1 hour before or 2 hours after meals.
What Is Localized Prostate Cancer
Prostate cancer is the abnormal growth of cells in the prostate gland. Localized prostate cancer has not spread outside the gland. Early prostate cancer usually doesnt cause symptoms.
Prostate cancer is the most common cancer in men. Most men who get it are older than 65. If your father, brother, or son has had prostate cancer, your risk is higher than average.
Men of African descent have the highest rates of both prostate cancer and deaths from it.
About 21,000 men are diagnosed with prostate cancer in Canada every year.footnote 1 In the United States, about 12 out of 100 men in the U.S. will be diagnosed with prostate cancer sometime in their lifetime.footnote 2 But most men who are diagnosed with prostate cancer dont die from prostate cancer.
Unlike many other cancers, prostate cancer is usually slow-growing. When prostate cancer is found earlybefore it has spread outside the glandit may be cured with radiation or surgery.
Prostate cancer that has grown beyond the prostate is called advanced prostate cancer. Treatment choices are different for that stage of cancer.

How Doctors Find Metastatic Prostate Cancer
When you are diagnosed with prostate cancer, your doctor will order tests such as:
- X-rays
- MRI scans
- PET scans
These tests may focus on your skeleton and in your belly and pelvic areas. That way doctors can check for signs that the cancer has spread.
If you have symptoms such as bone pain and broken bones for no reason, your doctor may order a bone scan. It can show if you have signs of cancer spread in your bones.
Your doctor will also ask for blood tests, including a check of PSA levels, to look for other signs that the cancer is spreading.
PSA is a protein made by the prostate gland. A rise in PSA is one of the first signs your cancer may be growing. But PSA levels can also be high without there being cancer, such as if you have an enlarged prostate a prostate infection, trauma to the perineum, or sexual activity can also cause PSA level to be high.
If you’ve been treated, especially if a surgeon removed your prostate, your PSA levels should start to go down. Doctors usually wait seve,ral weeks after surgery before checking PSA levels. A rise in PSA after treatment may suggest the possibility cancer is back or spreading. In that case, your doctor may order the same tests used to diagnose the original cancer, including a CT scan, MRI, or bone scan. The radiotracer Axumin could be used along with a PET scan to help detect and localize any recurrent cancer.
Though very rare, it’s possible to have metastatic prostate cancer without a higher-than-normal PSA level.
Survival Rates For Prostate Cancer
Survival rates can give you an idea of what percentage of people with the same type and stage of cancer are still alive a certain amount of time after they were diagnosed. These rates cant tell you how long you will live, but they may help give you a better understanding of how likely it is that your treatment will be successful.
Keep in mind that survival rates are estimates and are often based on previous outcomes of large numbers of people who had a specific cancer, but they cant predict what will happen in any particular persons case. These statistics can be confusing and may lead you to have more questions. Talk with your doctor about how these numbers may apply to you, as he or she is familiar with your situation.

Epidemiology Of Advanced Prostate Cancer
Approximately 11.6% of men will develop prostate cancer in their lifetime, with the likelihood increasing with age prostate cancer is most often diagnosed in men age 55 to 74 years, and the median age at diagnosis is 66 years. Since the advent of prostate-specific antigen screening, prostate cancer is being detected and treated earlier.
Overall, incidence rates of prostate cancer began declining in 2000. Acceleration in the decline began in 2008, when organizations began recommending against routine PSA screening From 2011 to 2015, the rate decreased by about 7% per year.
A review of almost 800,000 cases of prostate cancer diagnosed from 20042013 found that although the incidence of low-risk prostate cancer decreased from 2007-2013 to 37% less than that of 2004, the annual incidence of metastatic prostate cancer during those years increased to 72% more than that of 2004. The increase in metastatic prostate cancer was greatest in men aged 5569 years.
At diagnosis, 77% of prostate cancer cases are localized in 13%, the cancer has spread to regional lymph nodes, and 6% have distant metastasis. The 5-year relative survival rate for localized and regional prostate cancer is 100%, compared with 30.5% for metastatic cases.
The mortality rate associated with prostate cancer continues to increase in Europe and in countries such as Australia, Japan, and Russia.

Early Versus Delayed Treatment
In the years following the introduction by Huggins and Hodges of hormone therapy for prostate cancer, early institution of such treatment was recommended based on comparison with historical controls.
Later, the Veterans Administration Cooperative Urology Research Group studies reversed the recommendation of early hormone therapy instead, hormone therapy was deferred until symptomatic progression. In addition, prolongation of survival was believed to be secondary to the alteration of the nature of metastatic lesions, thereby creating earlier androgen resistance, rather than a result of early hormone manipulation.
In more recent years, the old controversy of appropriate androgen-deprivation therapy timing has gained new and stronger popularity because of the advent of less-toxic and well-tolerated pharmaceutical agents, such as luteinizing hormone-releasing hormone agonists and antiandrogens. Laboratory studies have demonstrated that early hormone therapy does not confer early resistance. An update of the VACURG study by Byar and Corle determined that disease progression from stage C to stage D was decreased from 50% to 10% with diethylstilbestrol therapy. Crawford and associates also showed a benefit of early hormone therapy in patients with distant metastases.
Should I Try A Clinical Trial
Researchers are actively conducting clinical trials to find better ways to treat metastatic prostate cancer and stop cancer spread. Many prostate cancer clinical trials focus on new therapies that target gene changes, as well as immunotherapies and chemotherapies.
Your doctor can help you determine if you might benefit from a clinical trial.

How Will My Cancer Be Monitored
Your doctor will talk to you about how often you should have check-ups. At some hospitals, you may not have many appointments at the hospital itself. Instead, you may talk to your doctor or nurse over the telephone. You might hear this called self-management.
You will have regular PSA tests. This is often a useful way to check how well your treatment is working. Youll also have regular blood tests to see whether your cancer is affecting other parts of your body, such as your liver, kidneys or bones.
You might have more scans to see how your cancer is responding to treatment and whether your cancer is spreading.
Your doctor or nurse will also ask you how youre feeling and if you have any symptoms, such as pain or tiredness. This will help them understand how youre responding to treatment and how to manage any symptoms. Let them know if you have any side effects from your treatment. There are usually ways to manage these.
What Is Stage 4 Prostate Cancer
Metastatic prostate cancer and stage 4 prostate cancer are the same thing. You may also know it as advanced prostate cancer. Cancer stage refers to how advanced or widespread the cancer is throughout your body. Doctors use a cancer staging system that includes Grade Groups and the Gleason score to determine prostate cancer stage.
Cancer staging occurs at the time of the initial prostate cancer diagnosis. However, prostate cancer can spread years later. If this happens, the stage or Grade Group changes.
