The Grade Group And Psa Level Are Used To Stage Prostate Cancer

Study Finds Surgery Effective for Patients with Aggressive Prostate Cancer – Mayo Clinic

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.

What Types Of Hormone Therapy Are Used For Prostate Cancer

Hormone therapy for prostate cancer can block the production or use of androgens . Currently available treatments can do so in several ways:

  • reducing androgen production by the testicles
  • blocking the action of androgens throughout the body
  • block androgen production throughout the body

Treatments that reduce androgen production by the testicles are the most commonly used hormone therapies for prostate cancer and the first type of hormone therapy that most men with prostate cancer receive. This form of hormone therapy includes:

Treatments that block the action of androgens in the body are typically used when ADT stops working. Such treatments include:

Treatments that block the production of androgens throughout the body include:

What Are Male Sex Hormones

Hormones are substances that are made by glands in the body. Hormones circulate in the bloodstream and control the actions of certain cells or organs.

Androgens are a class of hormones that control the development and maintenance of male characteristics. The most abundant androgens in men are testosterone and dihydrotestosterone .

Androgens are required for normal growth and function of the prostate, a gland in the male reproductive system that helps make . Androgens are also necessary for prostate cancers to grow. Androgens promote the growth of both normal and cancerous prostate cells by binding to and activating the androgen receptor, a protein that is expressed in prostate cells . Once activated, the androgen receptor stimulates the expression of specific genes that cause prostate cells to grow .

Almost all testosterone is produced in the testicles a small amount is produced by the adrenal glands. Although prostate cells do not normally make testosterone, some prostate cancer cells acquire the ability to do so .

Prostate Cancer Treatment Advances: Can They Help You

This page adheres to our medical and editorial policy and guidelines.

While the 10-year survival rate for men diagnosed with prostate cancer in the United States is approximately 98 percent, many men face difficult decisions about their treatment options. They worry not only about which treatment may be appropriate in fighting their cancer, but also about the impact treatment may have on their quality of life.

In 90 percent of cases, prostate cancer is diagnosed at the local or regional stage, meaning it hasnt spread beyond the prostate or nearby organs. Men diagnosed with early-stage prostate cancer may have several treatment options with similar outcomes. Men diagnosed with distant cancer, meaning its already spread to other areas of the body, face different treatment decisions. Either way, its normal to feel anxious after a diagnosis and to want to take action right away.

But you may regret rushing into a treatment plan without considering your options carefully. Prostate cancer treatment has common side effects, especially urinary incontinence and erectile dysfunction, that may negatively impact your quality of life. Because prostate cancer often progresses slowly, most men have time to investigate their options.

Whether youre already receiving treatment for prostate cancer, or youre considering new treatment decisions, its worth learning about prostate cancer treatment advances that may affect your choices.

Treating Stage Iii Bladder Cancer

Clinical trials

These cancers have reached the outside of the bladder and might have grown into nearby tissues or organs and/or lymph nodes . They have not spread to distant parts of the body.

Transurethral resection is often done first to find out how far the cancer has grown into the bladder wall. Chemotherapy followed by radical cystectomy is then the standard treatment.Partial cystectomy is rarely an option for stage III cancers.

Chemotherapy before surgery can shrink the tumor, which may make surgery easier. Chemo can also kill any cancer cells that could already have spread to other areas of the body and help people live longer. It can be especially useful for T4 tumors, which have spread outside the bladder. When chemo is given first, surgery to remove the bladder is delayed. The delay is not a problem if the chemo shrinks the cancer, but it can be harmful if it continues to grow during chemo. Sometimes the chemo shrinks the tumor enough that intravesical therapy or chemo with radiation is possible instead of surgery.

Some patients get chemo after surgery to kill any cancer cells left after surgery that are too small to see. Chemo given after cystectomy may help patients stay cancer-free longer, but so far its not clear if it helps them live longer. If cancer is found in nearby lymph nodes, radiation may be needed after surgery. Another option is chemo, but only if it wasnt given before surgery.

This Prostate Cancer Awareness Month Im Sharing Our Experience With The Disease

When my husband was diagnosed with prostate cancer in his mid 40s, we opted for a more aggressive treatment strategy, which led him being cancer-free and able to enjoy a healthy sex life.

During Prostate Cancer Awareness Month, I wanted to share a positive outcome and offer a bit of support and hope for men who might be newly diagnosed and in their 40s or 50s as well as their partners.

The topic of prostate cancer is important to me as my husband is a prostate cancer survivor. It was both concerning and shocking when he was diagnosed in his mid 40s.Fortunately, he was being screened at my request as I was aware of his family history of prostate cancer. We also had a cancer policy in place where we were refunded for yearly preventative screenings.

While I am grateful that he took my advice and requested a PSA as part of his annual physical and preventive screening, I was not fully prepared for the news and shock when he came back with results suggesting a prostate cancer diagnosis. The cancer diagnosis was eventually confirmed following a biopsy and the journey of what now began.

However, my husband and I learned from a close friend and physician that he has seen prostate cancer in younger men progress differently than men who are diagnosed in their late 60s or 70s. Our friend suggested removing the prostate and not to delay.

What Are Some Emerging Therapies For Prostate Cancer

Because prostate cancers can act so differently, they need different types of treatment. New research is focusing on precision medicine. The goal is to have tailored treatment for each person from the very beginning. Since there are so many different types of prostate cancer, precision medicine needs to cover a lot of bases. Its important to remember that not all emerging therapies are right for everyone. And the FDA hasnt approved some of these treatments yet. If you have advanced prostate cancer, talk to your team about whether you should try these emerging therapies:

  • Prostate membrane-specific antigen radionuclide therapy: PSMA radionuclide therapy delivers radiation directly to prostate cancer cells. A recent study showed that people with metastatic prostate cancer who received this therapy lived longer.

  • Focal therapies: Focal therapies use heat, cold, or electricity to kill cancer cells in the prostate gland and limit damage surrounding tissues. Therapies include focal irreversible electroporation, high-intensity focused ultrasound, cryotherapy, and focal laser ablation. These therapies are still investigational .

Transrectal Magnetic Resonance Imaging

This test is done to see whether the cancer has spread to other tissues that are nearby apart from the prostate. The test uses radio waves, a magnet, and a computer to create pictures of your bodys internal parts. This test uses a probe that is inserted inside your rectum. Through this test, your doctor can see your prostate and the tissues nearby.

Who Is At Risk Of Prostate Carcinoma

Treating Aggressive Prostate Cancer with Maha Hussain, MD

Scientists havent found the exact cause for prostate malignancy. But, like any other carcinoma, prostate cancer can develop in individuals with a family history of the disease or constant exposure to dangerous chemicals.

Whatever is causing the problem will trigger a cell mutation. This mutation is the one that causes the disease. Although prostate carcinoma can happen in any man, certain risk factors can make them more susceptible to the disease. These factors are:

For example, African Americans are found to have the highest risk of this particular illness. Also, those who are obese can become more vulnerable to the disease. Thats where understanding the risk factors could prove useful. It may help lessen the risk, particularly in older adults.

Your MDT will be able to recommend what they feel are the best treatment options, but ultimately the decision is yours.

You should be able to talk with a named specialist nurse about treatment options and possible side effects to help you make a decision.

You should also be told about any clinical trials you may be eligible for.

If you have side effects from treatment, you should be referred to specialist services to help stop or ease these side effects.

How Do You Determine Whats Right For You

Whether youve recently been diagnosed with prostate cancer or youre dealing with recurrent or metastatic cancer, you may be facing difficult decisions about your treatment. Its normal to be unsure about what steps to take, and most patients have more than one choice.

Start by talking to your oncologist about the specifics of your case and your options. The American Society of Clinical Oncology has a helpful list of questions to ask your doctor about prostate cancer you may want to reference.

If possible, see a multi-specialty cancer care team to get a bigger picture of your case and your options. This is also important because, sometimes, factors outside of your cancer stage may impact your treatment options. For example, you may have an obstruction in your urinary tract that makes surgery a more appropriate choice than radiation. Or maybe you have another health condition that makes surgery more risky for you. In that case, radiation may be a better choice. You want these doctors to talk to one another about your case each has expertise that makes an important contribution to the decision-making process. To facilitate this coordination, you may have to set up appointments to see multiple doctors and ask them to discuss your case.

Initial Treatment Of Prostate Cancer By Stage And Risk Group

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 haven’t spread , doctors also use risk groups to help determine if more tests should be done and to help guide treatment options. Risk groups range from very-low-risk to very-high-risk, with cancers in the lower risk groups 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 important 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. Taking part in a clinical trial of newer treatments is also an option for many men with prostate cancer.

I was stated on the hormone therapy called zoladex within 3 days. This stops the pituitary gland producing a hormone called LHRH, which then signals the testes not to produce testosterone. Reducing testosterone causes these tumours to shrink, at least initially. It also helps reduce the risk of cancer cells spreading elsewhere, if taken for a period of time after diagnosis.I then received 7 weeks of prostate and pelvic radiotherapy at the excellent Leeds St James-Bexley Wing. I continued to receive a 3 monthly Zoladex injection, along-side a daily anti-androgen Bicalutamide 50mg tablet until 2017.

My PSA dropped to < 0.05 ng/ml in 2015 and, unlike many other men, I had no significant side effects to all the treatments I have received. In 2017 I stopped Zoladex and I am very pleased that my latest PSA was 0.23 even with testosterone level of 19-20 nmol/L for the past year

Cancer May Spread From Where It Began To Other Parts Of The Body

When cancer spreads to another part of the body, it is called metastasis. Cancer cells break away from where they began and travel through the lymph system or blood.

  • Lymph system. The cancer gets into the lymph system, travels through the lymph vessels, and forms a tumor in another part of the body.
  • Blood. The cancer gets into the blood, travels through the blood vessels, and forms a tumor in another part of the body.

The metastatic tumor is the same type of cancer as the primary tumor. For example, if bladder cancer spreads to the bone, the cancer cells in the bone are actually bladder cancer cells. The disease is metastatic bladder cancer, not bone cancer.

What Is Prostate Cancer Ablation

To begin, its important to understand what ablation is. Ablation means the removal of diseased body tissue such as cancerous tumors. Image-guided ablation is performed by applying thermal energy that physically destroys the cancer. For prostate cancer, ablation is an alternative to surgery or radiation.

Thermal ablation for prostate cancer has two main advantages over surgery:

  • Same day outpatient procedure
  • Very rapid recovery time and return to normal activities

Ablation also has a unique advantage over surgery and radiation, which are both whole-gland treatments. Ablation can be done as a focal treatment with added benefits:

  • Targets only the tumor plus an extra safety margin
  • Avoids damage to healthy prostate tissue
  • Greatly reduces the risk of impaired urinary and sexual function as compared to surgery

Today, focal treatment for prostate cancer is recognized as an excellent option for patients who are accurately diagnosed and determined to be appropriate for a focal approach. Besides being clinically qualified, psychologically they desire high quality of life after treatment and are committed to actively participating in their doctors follow-up monitoring protocol using PSA blood tests and multi-parametric MRI scans at prescribed intervals.

Elsewhere in the paper, Cramer and his co-researchers show that the loss of the expression of the MAP3K7 gene, in particular, is associated with poor outcomes, making it even more vital to treat patients who show the loss of the gene. Cramer notes that the majority of men diagnosed with prostate cancer have slow-growing tumors that are at low risk for metastasis, but about 20% of patients will eventually develop aggressive metastatic disease. Knowing that the lack of MAP3K7 and CHD1 is a signal of a more aggressive disease, and that treatments such as surgery, radiation, chemotherapy, and hormonal therapy all have side effects that can be significant, Cramer hopes eventually doctors can use the deletion as a marker for men who would benefit most from aggressive treatment strategies and spare those who are less likely to succumb to their disease.

Those patients should be treated more aggressively than other patients because theyre more likely to die from the disease, he says. And we know that 50% of patients with loss of MAP3K7 and CHD1 are likely to recur after their primary treatment with recurrent disease.

Our ultimate goal is better treatment, he says. There is a lot more work that needs to be done to reproduce our findings, validate them, and then extend them into preclinical models. If those all look good, then patients could potentially be stratified based on their expression of these proteins, and then hopefully well have better ways to treat them.”
