Survival By Tumor Grade
One way cancer is staged is by looking at the grade of cancer. Grade refers to how cancer cells look like under a microscope.
Traditionally for prostate cancer, this has been done using the Gleason Score, which was developed in the 1960s. Under this system, cancerous cells are categorized on a scale from 1 to 5. Grade 1 cells are considered normal prostate tissues, while cells in the grade 5 range have mutated to such an extent they no longer resemble normal cells.
In determining a Gleason score, a pathologist will examine a biopsy sample under a microscope and give a Gleason grade using the above scale to the most predominant pattern displayed, then a second grade to the pattern that is the second most predominant. Those two grades are then added to form the overall Gleason score .
In theory, Gleason scores could range from 2 to 10, but pathologists today rarely give a score between 2 and 5 and are more likely to be in the range of 6 to 10 with 6 being the lowest grade of prostate cancer.
Under the Gleason Score system, a 6 is considered low grade, 7 is intermediate and scores of 8, 9, or 10 are considered high-grade cancers.
The higher the Gleason score, the more likely it is the prostate cancer will grow and spread quickly.
However, there have been some issues with the Gleason system, and a new grading system, to act as an extension of the Gleason system, has been developed.
Under this system Gleason scores are now categorized into grade groups:
Do You See A Urologist For Prostate Cancer
Often, if a physician suspects their patient has prostate cancer, they will refer them to a urologist for further evaluation. Urologists specialize in diagnosing and treating diseases of the urinary system, including prostate cancer. A urologist can conduct a biopsy to confirm a prostate cancer diagnosis. During the biopsy, a thin, hollow needle will be inserted into the prostate to collect a sample of prostate tissue. The needle may be inserted multiple times to collect several samples.
Within a few days, the urologist should have the diagnosis. If the biopsy is positive for prostate cancer, he or she will then stage the cancer and discuss the patients treatment options. Some patients with early-stage prostate cancer may be eligible for an active surveillance approach in which their condition will be monitored regularly. Treatment may be considered if the cancer begins to spread or cause symptoms.
The Grade Group And Psa Level Are Used To Stage Prostate Cancer
The stage of the cancer is based on the results of the staging and diagnostic tests, including the prostate-specific antigen test and the Grade Group. The tissue samples removed during the biopsy are used to find out the Gleason score. The Gleason score ranges from 2 to 10 and describes how different the cancer cells look from normal cells under a microscope and how likely it is that the tumor will spread. The lower the number, the more cancer cells look like normal cells and are likely to grow and spread slowly.
The Grade Group depends on the Gleason score. See the General Information section for more information about the Gleason score.
- Grade Group 1 is a Gleason score of 6 or less.
- Grade Group 2 or 3 is a Gleason score of 7.
- Grade Group 4 is a Gleason score 8.
- Grade Group 5 is a Gleason score of 9 or 10.
The PSA test measures the level of PSA in the blood. PSA is a substance made by the prostate that may be found in an increased amount in the blood of men who have prostate cancer.

Some Cancer Survival Statistics
Well, today were losing one person out of every two people with cancer. Now look back a 100 years ago. You know cancer wasnt even talked about hardly at all. And now were losing one out of two!
And the veterinarians are worse off than the medical doctors. Theyre losing one dog out of every 1.85 dogs. And Ive got some veterinarians now that are very excited about my program. Because I told them You guys are worse than the medical profession. What do you mean?! What do you mean?! I kind of get under their hide a little bit. Then I tell them, Listen, heres the reason. Or heres the statistics on it. 1 out of every 1.85 dogs die of cancer today. 1 out of 2 people die of cancer. So the medical doctors are doing a horrible job but theyre doing a better job than you guys are. Well then, he asks me, What do you think the reason is for that, Dennis?
Heres a vet asking me! Im not a vet, but I have the answer. I said If you could recommend a scientific dog food, and the other kind of dog foods out there, its the food thats killing people and killing dogs and giving them cancer. Thats why theyre dying. Really? I said Yeah, really. So we talked about that, and because I gave him that challenge What would you do? and so I told him. And so now hes enjoying some high, high, high survival rates with his pets, cats and dogs, so forth.
Who Gets This Cancer
Prostate cancer occurs only in men, and it is more common in older men than younger men. It is more likely to occur in men with a family history of prostate cancer and men of African American descent. The rate of new cases of prostate cancer was 111.3 per 100,000 men per year based on 20142018 cases, age-adjusted.

Stage 4 Prostate Cancer Clinical Trials
Clinical trials provide cancer patients with life-extending and curative new medicines. Clinical drug trials are critical in getting new medicines to patients who need them the most, as well as securing data so that regulatory clearances may be secured, and new drugs can enter broad clinical practice. Patients who take part in clinical trials benefit both treatment science and their fellow patients.
There are currently 100 Phase III drug trials and more than 500 Phase I/II trials related to prostate cancer treatment in progress in the United States alone. Those that are approved will join the 12 new drugs that have been approved for men with advanced/metastatic disease since 2010 and further improve outcomes for patients:

Coping With Prostate Cancer
The diagnosis of cancer can cause great anxiety to the individual and his family and friends. At times, one may have troubles coping with the diagnosis, the disease, and its treatment. Searching online for information may prove overwhelming also and may not be the best resource. Ask your physician or local hospital about local resources. Often, there are local prostate cancer support groups which may help you cope with your feelings and provide local resources for more knowledge.
You may consider contacting one or more of the following organizations:
- US Prostate Cancer Foundation,
- Centers for Disease Control and Prevention ,
- American Cancer Society, and
- Patient Advocates for Advanced Cancer Treatment.
The Internet has provided access to a number of sites focusing on prostate cancer treatment and outcomes. The National Cancer Institute and the National Comprehensive Cancer Network have patient information, as well as the American Urological Association.

Stage 4 Cancer Treatment Options
When it comes to treating Stage 4 cancer, there are a few different commonly used methods, which we will examine below.
Please keep in mind that whether or not an individual is a candidate for the following treatment options depends upon certain variables so it is always best to consult your doctor directly to find out which treatment option is most appropriate for you.
Where Prostate Cancer Spreads In The Body Affects Survival Time
EMBARGOED FOR RELEASE until 4 p.m. on Monday, March 7, 2016
DURHAM, N.C. Patients with lymph-only metastasis have the longest overall survival, while those with liver involvement fare worst. Lung and bone metastasis fall in the middle.
Smaller studies had given doctors and patients indications that the site of metastasis in prostate cancer affects survival, but prevalence rates in organ sites were small, so it was difficult to provide good guidance, said Susan Halabi, Ph.D., professor of biostatistics at Duke and lead author of the study published online March 7 in the Journal of Clinical Oncology.
With the large numbers we analyzed in our study, we were able to compare all of these different sites and provide information that could be helpful in conveying prognosis to patients, Halabi said. This information could also be used to help guide treatment approaches using either hormonal therapy or chemotherapy.
Halabi and colleagues from leading U.S. and international cancer research centers pulled data from nine large, phase III clinical trials to analyze outcomes of 8,736 men with metastatic prostate cancer. The patients had all undergone standard treatment with the chemotherapy drug docetaxel.
Site of metastases was categorized into four groups: lung, liver , lymph nodes only, bone with or without lymph nodes and no other organ metastases.
Halabi said more research is needed to understand how and why prostate cancer spreads to different organs.
Is Stage 4 Cancer Always Terminal
More severe cancers are more likely to be terminal. However, that is never a certainty. For example, the American Cancer Society say the 5-year survival rate for breast cancer that spreads to distant body parts is 27%, or 86% when it only spreads locally.
Determining the severity of cancer and its stage is a complex process. Doctors are still learning about all the factors that affect how cancer develops and affects the body.

Gleason Prostate Cancer Score
1960s as a way to measure how aggressive your prostate cancer may be.
A pathologist determines your Gleason score by looking at a biopsy of your prostate tissue under a microscope. They grade the cells in the biopsy on a scale of 1 to 5. Grade 1 cells are healthy prostate, whereas grade 5 cells are highly mutated and dont resemble healthy cells at all.
The pathologist will calculate your Gleason score by adding together the number of the most prevalent type of cell in the sample and the second most prevalent type of cell.
For example, if the most common cell grade in your sample is 4 and the second most common is 4, you would have a score of 8.
A Gleason score of 6 is considered low-grade cancer, 7 is intermediate, and 8 to 10 is high-grade cancer.

Experimental Treatments For Advanced Prostate Cancer
Researchers are currently testing many new approaches and treatments for prostate cancer, including new medications. These include the following:
Immune checkpoint inhibitors
The immune system uses âcheckpointsâ to stop it from attacking the bodyâs healthy cells. These checkpoints are proteins on immune cells.
Cancer cells often use these checkpoints to keep the immune system from attacking them.
Immune checkpoint inhibitors are drugs that can these checkpoints on cancer cells. Inhibiting these checkpoints can allow a personâs immune system to attack the cancer cells.
Chimeric antigen receptor T cell therapy
This treatment involves taking immune cells from the personâs blood. A scientist then alters these cells in a lab to have receptors called chimeric antigen receptors on their surface.
These receptors help the cells attach to proteins on the surface of prostate cells. A scientist then multiplies these altered T cells in a lab before putting them back into the personâs blood.
Scientists hope these T cells can then find prostate cancer cells and launch a targeted immune attack.
However, this treatment is complicated and may have some serious side effects. This means it is currently only available as part of clinical trials.
Targeted drug therapies
Targeted drug therapies can act on specific parts of cancer cells and the environments surrounding them.
Two possible targeted therapy treatments are:
Treating prostate cancer that has spread to the bones
Types Of Cancers That Are More Likely To Go Undetected
Some cancers are more easily detected than others. For example, certain types of skin cancer can be diagnosed initially just by visual inspection though a biopsy is necessary to confirm the diagnosis.
But other cancers can form and grow undetected for 10 years or more, as one study found, making diagnosis and treatment that much more difficult.
This table provides an overview of common cancers that often display little or no symptoms early on, and how theyre typically detected and diagnosed:

What Is The Survival Rate Of Stage 4 Prostate Cancer
Doctors use the term stage to characterize the characteristics of the original tumor itself, such as its size and how far prostate cancer has spread when it is discovered, as they do with all malignancies.
Staging systems are difficult to understand. Most malignancies, including prostate cancer, are staged using three different elements of tumor growth and dissemination. The TNM system stands for tumor, nodes, and metastasis:
- T, for tumor describes the size of the main area of prostate cancer.
- N, for nodes, describes whether prostate cancer has spread to any lymph nodes, and how many and in what locations.
- M, for metastasis, means distant spread of prostate cancer, for example, to the bones or liver.
The TNM approach allows each mans prostate cancer to be characterized in depth and compared to the prostate cancers of other men. Doctors utilize this information to conduct research and make treatment decisions.
However, in terms of prostate cancer survival statistics, the staging method is straightforward. As previously stated, males with prostate cancer can be split into two groups in terms of survival rates:
- Men with prostate cancer that is localized to the prostate or just nearby.
- Prostate cancer has a high long-term survival percentage in these men. Almost all men will live for more than five years after being diagnosed with prostate cancer, and many will live for much longer.
- Men whose prostate cancer has spread to distant areas, like their bones.
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. WhatÃ¢s 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?

Survival Rates By Tnm Stage
The first approach is based on the TNM stage statistical survival times are matched to the stage of the disease.
|TNM Lung Cancer Stage|
By contrast, the one-year survival rate for stage 4 lung cancer was reported in one study to be between 15% and 19%, meaning this portion of patients with metastatic disease lived for at least a year.

Eight Types Of Standard Treatment Are Used:
Watchful waiting or active surveillance
Watchful waiting and active surveillance are treatments used for older men who do not have signs or symptoms or have other medical conditions and for men whose prostate cancer is found during a screening test.
Active surveillance is closely following a patients condition without giving any treatment unless there are changes in test results. It is used to find early signs that the condition is getting worse. In active surveillance, patients are given certain exams and tests, including digital rectal exam, PSA test, transrectal ultrasound, and transrectal needle biopsy, to check if the cancer is growing. When the cancer begins to grow, treatment is given to cure the cancer.
Other terms that are used to describe not giving treatment to cure prostate cancer right after diagnosis are observation, watch and wait, and expectant management.

Survival For All Stages Of Prostate Cancer
Generally for men with prostate cancer in England:
- more than 95 out of 100 will survive their cancer for 1 year or more
- more than 85 out of 100 will survive their cancer for 5 years or more
- almost 80 out of 100 will survive their cancer for 10 years or more
Survival of prostate cancer is also reported in Scotland and Northern Ireland. But it is difficult to compare survival between these countries because of differences in the way the information is collected.
Cancer survival by stage at diagnosis for England, 2019Office for National Statistics
These statistics are for net survival. Net survival estimates the number of people who survive their cancer rather than calculating the number of people diagnosed with cancer who are still alive. In other words, it is the survival of cancer patients after taking into account the background mortality that they would have experienced if they had not had cancer.
