What Are Prostate Cancer Survival Rates By Stage
Staging evaluation is essential for the planning of treatment for prostate cancer.
- A basic staging evaluation includes the patient examination, blood tests, and the prostate biopsy including ultrasound images of the prostate.
- Further testing and calculations may be performed to best estimate a patient’s prognosis and help the doctor and patient decide upon treatment options.
Prognosis refers to the likelihood that cancer can be cured by treatment, and what the patient’s life expectancy is likely to be as a consequence of having had a prostate cancer diagnosis.
If cancer is cured, your life expectancy is what it would have been had you never been diagnosed with prostate cancer. If cancer cannot be cured due to it recurring in distant locations as metastases, or recurs either locally or in an area no longer able to be treated in a curative manner, then estimates can be made of what is likely to be your survival-based again on group statistics for people who have been in the same situation.
Nomograms are charts or computer-based tools that use complex math from the analysis of many patients’ treatment results.
The prognosis for prostate cancer varies widely and depends on many factors, including the age and health of the patient, the stage of the tumor when it was diagnosed, the aggressiveness of the tumor, and cancer’s responsiveness to treatment, among other factors.

What Is The Normal Gleason Score
Theoretically, Gleason scores range from 2-10. However, since Dr. Gleasons original classification, pathologists almost never assign scores 2-5, and Gleason scores assigned will range from 6 to 10, with 6 being the lowest grade cancer.
Otherwise, is a Gleason score of 9 a death sentence?
Not all men with Gleason 8-10 disease are going to do badly after treatment. There is a perception among a lot of patients especially when they get diagnosed that having a high Gleason score of 8, 9, or 10 is essentially a death sentence, regardless of how they get treated. This is not actually the case at all.
Although, is Gleason score the same as PSA? A Gleason score of 8 or higher, accompanied by a PSA level of higher than 20 ng/ml and a more advanced tumor stage, signifies a high risk of advancing cancer. In high-risk cases, the prostate cancer tissue looks very different from normal tissue.
So too, what is a Gleason score of 7 mean?
A Gleason score of 7 is a medium-grade cancer, and a score of 8, 9, or 10 is a high-grade cancer. A lower-grade cancer grows more slowly and is less likely to spread than a high-grade cancer.
What if prostate biopsy is positive?
If prostate cancer is found on a biopsy, it will be assigned a grade. The grade of the cancer is based on how abnormal the cancer looks under the microscope. Higher grade cancers look more abnormal, and are more likely to grow and spread quickly.

Does Overdiagnosis Lead To Overtreatment Of Older Men
The widespread use of PSA screening has led to an increase in the diagnosis and treatment of early localized prostate cancer. Data from the US Cancer of the Prostate Strategic Urological Research Endeavor database suggest a significant decrease in risk in the last 2 decades in the United States, with more patients being identified with low-risk disease at diagnosis, but the role of active treatment of low- and intermediate-risk disease in elderly men remains controversial.
The median time from diagnosis to death from prostate cancer for men with nonpalpable disease is approximately 17 years., Considering that the US male life expectancy at the age of 65 years is 16 years, aggressive therapy will hardly extend life expectancy of older men with no palpable prostate cancer at the time of diagnosis. Twenty to 30% of prostate cancers detected by PSA screening programs show Gleason scores of 6 or lower and, thus, are not poorly differentiated and have volumes smaller than 0.5 cm3.
Histologic evaluation of radical prostatectomy specimens demonstrated that about 20% to 30% of cancers are small volume, show low Gleason scores, and are consequently clinically harmless., Many of these cancers pose little threat to life, especially for older men. Has PSA screening resulted in prostate cancer overdiagnosis?

How Is Prostate Cancer Staged
Prostate cancer is one of the most common types of cancer that develops in men and is the second leading cause of cancer deaths in American men, behind lung cancer and just ahead of colorectal cancer. The prognosis for prostate cancer, as with any cancer, depends on how advanced the cancer has become, according to established stage designations.
The prostate gland is a walnut-sized gland present only in men, found in the pelvis below the bladder. The prostate gland wraps around the urethra and lies in front of the rectum. The prostate gland secretes part of the liquid portion of the semen, or seminal fluid, which carries sperm made by the testes. The fluid is essential to reproduction.
The term to stage a cancer means to describe the evident extent of the cancer in the body at the time that the cancer is first diagnosed.
- Clinical staging of prostate cancer is based on the pathology results, physical examination, PSA, and if appropriate, radiologic studies.
- The stage of a cancer helps doctors understand the extent of the cancer and plan cancer treatment.
- Knowing the overall results of the different treatments of similarly staged prostate cancers can help the doctor and patient make important decisions about choices of treatment to recommend or to accept.
Changes In Psa Levels After Surgery
In patients with rising PSA levels after radical prostatectomy, the important prognostic factors are the :
- pathologic stage
- time taken post-operatively to reach detectable PSA levels
- Gleason score at the time of prostatectomy
- time required for doubling of PSA values
PSA doubling time of 15 months or more are better managed with surveillance. The have median time to metastatic disease in these years is about 8 years and the median survival is about 13 years. Patients with PSA doubling times of less than 3 months are at very high risk of prostate cancer related death and have a median survival of 5 to 6 years.

What Does It Mean If In Addition To Cancer My Biopsy Report Also Mentions Acute Inflammation Or Chronic Inflammation
Inflammation of the prostate is called prostatitis. Most cases of prostatitis reported on biopsy are not caused by infection and do not need to be treated. In some cases, inflammation may increase your PSA level, but it is not linked to prostate cancer. The finding of prostatitis on a biopsy of someone with prostate cancer does not affect their prognosis or the way the cancer is treated.

What Is A Bad Gleason Score For Prostate Cancer
Gleason scores aren’t good or bad, per se. They predict how quickly your prostate cancer might grow. Tumors with higher Gleason scores are likely to grow quickly. And Gleason scores aren’t the only factors healthcare providers consider when creating your treatment plan.
What other factors do healthcare providers consider?
Providers consider the results of other tests and additional biopsy information. For example, when you had your biopsy, your healthcare provider obtained several samples or cores from your prostate. They checked how many cores contained cancer and whether most of the cells in the cores were cancerous cells.
Other factors may include:

What Does It Mean If My Biopsy Mentions That There Is Perineural Invasion
Perineural invasion means that cancer cells were seen surrounding or tracking along a nerve fiber within the prostate. When this is found on a biopsy, it means that there is a higher chance that the cancer has spread outside the prostate. Still, perineural invasion doesnt mean that the cancer has spread, and other factors, such as the Gleason score and amount of cancer in the cores, are more important. In some cases, finding perineural invasion may affect treatment, so if your report mentions perineural invasion, you should discuss it with your doctor.
Outlook For Locally Advanced Prostate Cancer
Many men with locally advanced prostate cancer have treatment that aims to get rid of their cancer. For some men, this treatment can be very successful and they may live for many years without their cancer coming back or causing them any problems. For others, treatment may be less successful and the cancer may come back. If this happens, you might need further treatment. Read more about the risk of your cancer coming back.
Some men with locally advanced prostate cancer will have treatment that aims to help keep their cancer under control rather than get rid of it completely. For example, if you have hormone therapy on its own, it can help to keep the cancer under control, usually for several years. And there are other treatments available if your hormone therapy stops working.

What Are The Stages Of Prostate Cancer
Cancer staging is first described using what is called a TNM system. The âTâ refers to a description of the size or extent of the primary, or original, tumor. âNâ describes the presence or absence of, and extent of spread of cancer to lymph nodes that may be nearby or further from the original tumor. âMâ describes the presence or absence of metastases â usually distant areas elsewhere in the body other than regional lymph nodes to which cancer has spread. Cancers with specific TNM characteristics are then grouped into stages, and the stages are then assigned Roman numerals with the numerals used in increasing order as the extent of the cancer being staged increases or the cancer prognosis worsens. Prognosis is finally reflected by considering the patientâs PSA score at presentation as well as their Gleason score in assigning a final stage designation.
The American Joint Commission on Cancer system for prostate cancer staging is as follows:
The primary tumor
Traditionally, advanced prostate cancer was defined as a disease that had widely metastasized beyond the prostate, the surrounding tissue, and the pelvic lymph nodes and was incurable. However, a more contemporary definition includes patients with the lower-grade disease with an increased risk of progression and/or death from prostate cancer in addition to those with widely metastatic disease.
CT scan is used for the initial staging in select patients including

Gleason Score Vs Grade Groups
The International Society of Urological Pathology released a revised prostate cancer grading system in 2014. The grade group system seeks to simplify Gleason scores and give a more accurate diagnosis.
One of the major problems with the Gleason score is that some scores can be made up in different ways. For example, a score of 7 can mean:
- 3 + 4. The 3 pattern is the most common in the biopsy and 4 is the second most common. This pattern is considered favorable intermediate risk.
- 4 + 3. The 4 pattern is the most common in the biopsy and 3 is the second most common. This pattern is considered unfavorable and may mean local or metastatic spread.
So, although both situations give a Gleason score of 7, they actually have very different prognoses.
Heres an overview of how the two grading systems compare:
|grade group 5||910|
Not all hospitals have switched to the grade group system. Many hospitals give both grade group and Gleason scores to avoid confusion until grade groups become more widely used.

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.

What Is The Gleason Grading System
Your Gleason score isnt a separate test. Its a number based on the results of your biopsy. You usually get it when youre 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. Theyll use this information to suggest the best treatment for you.
Survival By Disease Progression
The extent prostate cancer has progressed can influence survival rates.
Prostate-specific antigen is a protein produced by cells of the prostate gland by normal and malignant cells. In men with prostate cancer, blood levels of PSA are often elevated.
Doctors can use PSA as a marker to better understand the progression of prostate cancer and the resulting prognosis.
One way doctors assess the progression of the disease is through PSA doubling time. This refers to the number of months it takes for PSA to double.
One study suggests a short doubling time means a poorer prognosis for patients with stage IV prostate cancer. Median survival was 16.5 months for those with a PSA doubling time lower than 45 days compared with 26 months for patients with a longer PSA doubling time.
Whether or not the cancer has metastasized and spread to other areas of the body outside the prostate can also influence survival. In distant or stage IV prostate cancer, when cancer has spread from the prostate to other organs like the liver or lungs, the five-year survival rate is 31% compared with localized cancer, which has a five-year survival rate of nearly 100%.

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.
