Watchful Waiting Or Active Surveillance

How is stage 4 prostate cancer treated? – Dr. Anil Kamath

Prostate cancer treatments can have side effects. If you’re worried about these risks, you can decide to hold off on these treatments and see if your tumor grows. Waiting is also an option if youâre older, your cancer is growing slowly, or you don’t have symptoms that bother you.

Waiting does not mean that you do nothing about your cancer. Your doctor will keep a close eye on the tumor and watch for any signs that itâs getting worse.

Watchful waiting means you and your doctor will look out for symptoms. The doctor may do tests from time to time to make sure the cancer hasn’t grown.

Active surveillance means your doctor will do tests, including PSA blood tests and rectal exams, usually about every 3-6 months to check on it. You may also have a biopsy, when a doctor takes a small piece of tissue from your prostate and checks it for cancer.

What Does It Mean For Prostate Cancer To Spread

Cancer cells can spread to other parts of the body. Doctors say the cancer has âmetastasizedâ or spread if this occurs.

Prostate cancer can spread to:

These symptoms can also occur with aging and an enlarged prostate. As a result, some people may ignore them instead of seeking medical attention.

According to the Prostate Cancer Foundation, age is the biggest contributing factor to prostate cancer risk. Doctors diagnose an estimated 60% of all prostate cancers in males older than 65 years of age.

It states that additional risk factors for prostate cancer include:

  • Family history: People with a close relative who has had prostate cancer may be twice as likely to get prostate cancer as those who do not.
  • Race: Males of African descent are about 75% more likely to develop prostate cancer than white males and more than twice as likely to die from the condition.
  • Smoking: A history of smoking is associated with a higher risk of aggressive prostate cancer.

Researchers are also studying a link between diet and increased prostate cancer risk. Diets high in calcium or low in vegetables may cause an increased risk of aggressive prostate cancer.

What Is Stage 4 Prostate Cancer

The fourth stage of prostate cancer defines a tumor that has progressed to other regions of the body, such as the lymph nodes, lungs, liver, bones, or bladder. The 5-year survival rate for these tumors is 29 percent.

Keep in mind that each case is unique, and figures like these are merely suggestions. As advances in prostate cancer treatment become more common, your odds of surviving this disease improve.

In general, prostate cancer has a very good survival rate one of the greatest of any cancer type. Because prostate cancer is frequently a slow-moving disease, the majority of men diagnosed with it will die from an unrelated reason.

Stage 4 prostate cancer means the cancer has spread to lymph nodes or to other parts of the body. It is further divided into two substages:

  • Prostate Cancer Stage 4A Stage 4A: The cancer has spread to nearby lymph nodes but may or may not have spread to nearby tissues.
  • Prostate Cancer Stage 4B Stage 4B: The cancer has spread to another area of the body, such as the bones or distant lymph nodes.

Staging Of Prostate Cancer

Doctors will use the results of your prostate examination, biopsy and scans to identify the stage of your prostate cancer .

The stage of the cancer will determine which types of treatments will be necessary.

If prostate cancer is diagnosed at an early stage, the chances of survival are generally good.

Treatment Options Under Clinical Evaluation

Prostate Cancer Stages

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.

Strategies To Improve Treatment

The progress that has been made in the treatment of prostate cancer has resulted from development of better treatments that were evaluated in clinical studies. Future progress in the treatment of prostate cancer will result from patients continued participation in appropriate clinical trials. Developing novel precision cancer medicines and immunotherapies is the main area of active current investigation.

Cabazitaxel : Cabazitaxel is administered intravenously and has been demonstrated to improve time to cancer progression and overall survival in men with HRPC previously treated with docetaxel. Cabazitaxels primary side effect is neutropenia, and it is recommended that patients receive a white blood cell growth factor if they are at high risk of this complication.

Sipuleucel-T: Sipuleucel-T is an immunotherapy that prompts the bodys immune system to respond against the cancer. A Phase III clinical trial that contributed to the FDA approval of sipuleucel-T was a study known as IMPACT which demonstrated an improvement in overall survival for men treated with sipuleucel-T. The main side effects reported were chills, fever, and headache.

Life Expectancy Of Stage 4 Liver Cancer

Life Expectancy of Stage 4 Liver Cancer is not very impressing at all. The stage is concerned as one of the most critical Liver Cancer. The impact of the Liver Cancer Stage 4 is very bad, and the condition gets worse with time. On average patient may survive for 6 months. However, if the complexity of Liver is less then, people may survive for even couple of years. However, the life expectancy of Stage 4 depends upon the condition of the people.

How Is Stage Iv Prostate Cancer Treated

The treatment methods for stage IV of prostate cancer include:

  • Hormone therapy along with chemotherapy
  • External beam radiation along with hormone therapy
  • Radical prostatectomy if the cancer has not spread to the lymph nodes
  • Surgery to relieve symptoms
  • Clinical trials

External beam radiation:

It is a type of radiation therapy, a treatment method that involves use of high beams of X rays to kill cancerous cells. In external beam radiation therapy, also called EBRT, beams of radiation are focused on the prostate gland from a machine outside the body and it is used to treat the early stages of cancer.

Brachytherapy:

Brachytherapy is a type of radiation therapy too. Also called seed implantation or interstitial radiation therapy, small radioactive pellets of the size of a grain of rice are placed directly inside the prostate gland. This treatment is used alone in patients in the early stages of cancer showing relatively slow growth. Otherwise, this is preferred in combination of other treatment methods.

Chemotherapy For Metastatic Prostate Cancer

Chemotherapy may be used for patients with metastatic prostate cancer, with the aim of slowing any further spread of cancer and improving quality of life.

The most commonly used chemotherapy medications, typically given via an intravenous line, are docetaxel combined with prednisone. However, there are several chemotherapy drugs available, so ask your doctor which types may be most appropriate for your treatment.

In some cases, these treatments are considered palliative, intended to relieve difficult symptoms and improve quality of life.

Clinical Trials For Advanced Disease

Clinical trials are investigational studies that are conducted to find new treatments in the fight against prostate cancer. The drug development process can take many years and is well regulated by federal agencies. Many times, participation in a clinical trial is a way to receive a promising new drug that has not yet been approved by the FDA. Several new drugs are currently under investigation for advanced prostate cancer. .

Are There Side Effects Of The Combination Approach To Prostate Cancer Radiation Therapy

When it comes to early stages of disease, patients very frequently do well with either brachytherapy or external beam radiation. Success rates of around 90% or higher can be achieved with either approach. When the disease is somewhat more advanced based on the PSA level, Gleason score, extent of visible disease on magnetic resonance imaging we have learned over the years that higher doses of radiation are critical to achieving better results. Some evidence, including a large trial, suggests that for patients with intermediate- or high-risk prostate cancer, a combined approach using brachytherapy along with external beam radiation may be best compared to standard dose external beam radiation therapy alone.

Survival Of Prostate Cancer

Survival depends on many factors. No one can tell you exactly how long you will live.

Below are general statistics based on large groups of people. Remember, they cant tell you what will happen in your individual case.

Survival for prostate cancer is generally good, particularly if you are diagnosed early.

The 4 Types of Prostate Cancer Treatment | Prostate Cancer Staging Guide

Different treatments may be recommended for each stage of prostate cancer. Your doctor will work with you to develop a specific treatment plan based on the cancers stage and other factors. Detailed descriptions of each type of treatment are provided earlier on this same page. Clinical trials may also be a treatment option for each stage.

Early-stage prostate cancer

Early-stage prostate cancer usually grows very slowly and may take years to cause any symptoms or other health problems, if it ever does at all. As a result, active surveillance or watchful waiting may be recommended. Radiation therapy or surgery may also be suggested, as well as treatment in clinical trials. For those with a higher Gleason score, the cancer may be faster growing, so radical prostatectomy and radiation therapy are often recommended. Your doctor will consider your age and general health before recommending a treatment plan.

ASCO, the American Urological Association, American Society of Radiation Oncology, and the Society of Urologic Oncology recommend that patients with high-risk early-stage prostate cancer that has not spread to other areas of the body should receive radical prostatectomy or radiation therapy with hormonal therapy as standard treatment options.

Locally advanced prostate cancer

Watchful waiting may be considered for older adults who are not expected to live for a long time and whose cancer is not causing symptoms or for those who have another, more serious illness.

Stage 4 Prostate Cancer: Survival Rates Treatment And Support

Prostate cancer is in stage 4 when the cancer spreads beyond the lymph nodes and into other areas of the body. While the vast majority of prostate cancer cases are caught before this happens, when the cancer is treatable, stage 4 is far more difficult to treat. Therefore, the survival rate among men with stage 4 prostate cancer is much lower.

There are two types of stage 4 prostate cancer: 4A and 4B, according to the American Cancer Society. The type assigned to a persons diagnosis is based on whether the cancer has spread and to what degree, and the value assigned to two additional factors called the Grade Group and the prostate-specific antigen . The Grade Group is a measure of how likely the cancer is to spread quickly, and the PSA is a measure of a protein in the blood produced by cells in the prostate.

With stage 4A, the tumor has already spread into the lymph nodes and may be spreading into tissues adjacent to the prostate, but has not spread to other areas of the body. The Grade Group can be of any value, as can the PSA.

With stage 4B, the tumor may have spread into the lymph nodes, may be spreading into nearby tissues and has spread to other areas of the body like the bones, certain organs and distant lymph nodes. The Grade Group and PSA can be of any value.

What Treatments Are Available

If you have advanced prostate cancer, treatment wont cure your cancer. But it can help keep it under control and manage any symptoms.

If youve just been diagnosed with advanced prostate cancer, you may be offered the following treatments:

Research has found that having radiotherapy together with one of the main treatments listed above can help some men with advanced prostate cancer to live longer. But radiotherapy isnt suitable for all men with advanced prostate cancer.

If you live in Scotland, you may also be offered a type of hormone therapy called abiraterone acetate together with standard hormone therapy. In the rest of the UK, abiraterone is currently only given to men with advanced prostate cancer that has stopped responding to other types of hormone therapy. The National Institute for Health and Care Excellence is currently deciding whether to make it available for men who have just been diagnosed with advanced prostate cancer.

Before you start treatment

Before you start any treatment, make sure you have all the information you need. Its important to think about how you would cope with the possible side effects. Speak to your doctor or nurse about this.

It can help to write down any questions you want to ask at your next appointment. It may also help to take someone with you, such as your partner, a family member or friend.

If you have any questions, speak to our Specialist Nurses.

Stage 4 Prostate Cancer Prognosis

Doctors need to know how far the cancer has advanced, or its stage, in order to choose the best treatment. A pathologist, a specialist who specializes in studying cells obtained from a prostate biopsy, will provide two starting points: the 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 reveals prostate cancer, the patient may be subjected to additional testing to determine whether the disease has spread to other regions of the body via the blood or lymph nodes. These are typically imaging examinations, such as a bone scan, positron emission tomography scan, or computed tomography scan.
