Chemical castration is used to treat hormone-dependent cancers, such as prostate cancer. Lowering androgens can help slow cancer growth and metastasis. Chemical castration may be beneficial for prostate cancer that has spread or recurred after first-line treatment.
How do medications for chemical castration treat prostate cancer?
Here are the categories of medications used for chemical castration to treat prostate cancer: These medications stop the pituitary gland from releasing luteinizing hormone that tells the testicles to make testosterone. First, however, they cause a high level of hormone that’s eventually ignored.
Can castrate-resistant prostate cancer be cured?
In men with castrate-resistant prostate cancer, the cancer still continues to progress, despite the decrease in testosterone. If your prostate cancer advances and becomes castrate resistant, there are therapies that can help slow the advance of the disease, although they do not cure the cancer. One key goal is keeping the cancer from metastasizing.
Is androgen-deprivation therapy the best treatment for metastatic castration-sensitive prostate cancer?
Abstract Standard treatment for metastatic castration-sensitive prostate cancer (mCSPC) was androgen-deprivation therapy (ADT) for >7 decades, and this was termed the “all-comers” approach. A remarkable evolution in the treatment of mCSPC has been noted in the previous several years.
When to use external beam radiation therapy for prostate cancer?
After treatment of prostate cancer, if the prostate-specific antigen (PSA) level remains high or starts rising. In locally advanced prostate cancer, to make external beam radiation therapy more effective in reducing the risk of recurrence
Why is castration at first effective in helping prostate cancer?
Orchiectomy (surgical castration) Even though this is a type of surgery, its main effect is as a form of hormone therapy. In this operation, the surgeon removes the testicles, where most of the androgens (such as testosterone and DHT) are made. This causes most prostate cancers to stop growing or shrink for a time.
Is castration a good treatment for prostate cancer?
Androgen-deprivation therapy (ADT) with surgical or pharmacological castration has long been a mainstay of treatment for metastatic prostate cancer. However, due to concerns about cosmetic and psychological effects of surgical castration, that practice has been nearly eliminated in favor of medical castration.
Why is orchiectomy done in prostate cancer?
Surgery Overview Orchiectomy is the removal of the testicles. The penis and the scrotum, the pouch of skin that holds the testicles, are left intact. An orchiectomy is done to stop most of the body's production of testosterone, which prostate cancer usually needs in order to continue growing.
What is the effect of castration in prostate carcinoma?
Common side effects of castration are e.g. sweating, increased body fat, decreased muscle mass, impotency and anemia. Castration increases the risk of osteoporosis and fractures in prostate cancer patients via hormonal effects to the bone. Castrated men should be recommended to increase physical activity.
What are the benefits of human castration?
Body strength and muscle mass can decrease. Bone structure becomes softer and more slender. Body hair may sometimes decrease and is less coarse. Castration stops the progression of male pattern baldness.
Does castration prevent cancer?
Health Benefits of Spaying and Neutering In males, neutering decreases the chances of developing prostatic disease and hernias, and eliminates the chances of developing testicular cancer.
What are the benefits of an orchiectomy?
It's commonly performed to treat or prevent prostate cancer from spreading. An orchiectomy can treat or prevent testicular cancer and breast cancer in men, too. It's also often done before sexual reassignment surgery (SRS) if you're a transgender woman making the transition from male to female.
Which is better for a prostate cancer patient orchiectomy or hormone treatment?
Conclusion: Advanced prostate carcinoma patients with poor pretreatment prognosis scores should undergo surgical castration rather than medical castration for better PSA rebound rates and overall survival.
What happens to a man after orchiectomy?
If both your testicles were removed, you may start to notice changes in your body several weeks after surgery due to not having male hormones. The most obvious changes may be hot flashes and sweating. You may lose your sex drive, gain weight, or not be able to get an erection. These changes can be upsetting.
Is prostate removal the same as castration?
The surgical removal of the testes is sometimes called castration, but it's more formally known as orchiectomy. The testicles produce androgens, so removing them causes hormone levels to plummet. Androgens are male sex hormones. Low testosterone levels usually slow the advance of prostate cancer.
What happens when a man is chemically castrated?
Chemical castration is administered with oral medication, injections, or an implant under your skin. This affects hormone levels, but there's no immediate change in the appearance of your testicles. However, they may shrink over time. In some cases, your testicles can become so small that you can't feel them.
Is prostate removal castration?
For some men with metastatic prostate cancer, surgical castration to remove the testicles (orchiectomy) could be a better option than "chemical castration" achieved by long-term use of prostate gonadotropin-releasing hormone (GnRH) agonist products, as it may carry less risk for adverse events, suggests a new study ...
How does prostate cancer treatment work?
New drugs, and new combinations of drugs and other treatments, are under development. The treatments both extend life and improve quality of life by reducing pain, urinary problems, and other complications of cancer that has spread outside the prostate gland.
How to treat metastatic prostate cancer?
Metastatic prostate cancer frequently spreads to the bones. Bone tumors can cause fractures and severe pain. Treatment for bone tumors is palliative. That means it’s intended to minimize symptoms rather than to cure the disease. They include: 1 External-beam radiation. This involves radiation therapy being administered from outside the body. 2 Denosumab (Xgeva, Prolia). This drug helps reduce bone damage caused by prostate cancer. 3 Radium-233 (Xofigo). This unique form of radiation therapy is injected into the bloodstream and specifically targets prostate cancer tumors in bones. The radium accumulates in areas of bone where tumors are forming. The effect of the radioactivity acts over a very short distance, killing tumor cells with less damage to nearby healthy bone. In a clinical trial, men treated with radium-233 survived several months longer than men who got an inactive placebo injection.
What does it mean when your prostate antigen levels rise?
After you begin hormone treatment, your doctor will regularly measure levels of prostate-specific antigen (PSA) in your blood. PSA is a protein produced by prostate cancer cells. If PSA levels start to rise while you are on hormone therapy, this can be a sign that the treatment has stopped working and the cancer has become castrate resistant.
What is ADT in prostate cancer?
Several different types of ADT medications interfere with or block the processes in the body that control the production of androgens that cause prostate cancer cells to multiply . The drugs are essentially a form of “chemical castration.”.
What is castrate resistant prostate cancer?
Castrate-resistant prostate cancer is prostate cancer that stops responding to hormone therapy. Hormone therapy, also called androgen deprivation therapy (ADT), dramatically lowers testosterone levels in the body. The testosterone levels are comparable to levels in men who have had their testicles surgically removed.
What hormones are involved in prostate cancer?
The main hormone that drives prostate cancer is testosterone, which is produced in the testicles. ADT drastically lowers levels of testosterone and other androgens in the body, and stalls the advance of the cancer in many men — but only temporarily. For reasons that remain poorly understood, prostate cancer cells can adapt to lower levels ...
How to treat prostate cancer in men?
Men typically have surgery to remove the cancerous prostate gland or radiation treatment to destroy the cancerous cells in the gland. If early-stage cancer comes back after surgery or radiation, or has begun to spread to more distant parts of the body (metastasize), treatment with hormone-blocking drugs can slow the advance ...
Is bilateral orchiectomy effective?
Bilateral orchiectomy is as effective as gonadotropin-releasing hormone agonists in controlling prostate cancer. Bilateral orchiectomy is as effective as treatment with gonadotropin-releasing hormone agonists (GnRHa) in controlling prostate cancer and is associated with fewer clinically relevant adverse events, a population-based study has found. 1.
Is castration a treatment for metastatic prostate cancer?
Androgen-deprivation therapy (ADT) with surgical or pharmacological castration has long been a mainstay of treatment for metastatic prostate cancer. 2 However, due to concerns about cosmetic and psychological effects of surgical castration, that practice has been nearly eliminated in favor of medical castration.
Castration
A standard treatment to reduce the production of testosterone in the belief this promotes PCa was based on work done by Dr Charles Huggins in 1940 when he began castrating men to reduce testosterone to zero. In 1966 he was awarded the Nobel Prize for his work.
Study finds no increase in cancer in association with testosterone replacement therapy
Tuesday, June 4, 2013.A study reported at the American Urological Association’s meeting held this year in San Diego found that men who used testosterone replacement therapy (TRT) had a similar risk of developing cancer in comparison with those who did not use the hormone.
What is castration resistant prostate cancer?
What is castration-resistant prostate cancer? Castration-resistant prostate cancer is a type of prostate cancer that usually develops during treatment for metastatic disease. Hormonal therapy either stops the production or blocks the action of androgens.
What is the best treatment for prostate cancer?
Anti- androgen therapy. Oestrogen therapy. Adrenolytic agents. Immunotherapy. Chemotherapy. Radiation therapy. Because castration-resistant prostate cancer still responds to androgens, your doctor will recommend to continue hormonal treatment to keep the levels of testosterone low.
Why are prostate cancers called castration resistant?
These cancers are called castration-resistant, because they no longer respond to hormonal castration treatment.
How long does castration last?
This effect will not last and leads to castration-resistant prostate cancer. This generally happens 2-3 years after hormonal treatment started. Castration -resistant prostate cancer cannot be cured.
Can prostate cancer be diagnosed by PSA?
In this type of cancer, the level of prostate-specific antigen (PSA) in the blood rises again. The doctor will diagnose castration-resistant prostate cancer if repeated tests show an increase in the PSA level in your blood. It can also be diagnosed if you experience symptoms caused by the growing tumour or metastases.
What are the drugs that help prostate cancer grow?
Anti-androgens. For most prostate cancer cells to grow, androgens have to attach to a protein in the prostate cancer cell called an androgen receptor. Anti-androgens are drugs that also connect to these receptors, keeping the androgens from causing tumor growth.
What does CSPC mean in prostate cancer?
Castrate-sensitive prostate cancer (CSPC) means the cancer is being controlled by keeping the testosterone level as low as what would be expected if the testicles were removed (called the castrate level ).
What is the goal of hormone therapy?
The goal is to reduce levels of male hormones, called androgens, in the body, or to stop them from fueling prostate cancer cells. Androgens stimulate prostate cancer cells to grow. The main androgens in the body are testosterone ...
What hormones are used to remove testicles?
Estrogens (female hormones) were once the main alternative to removing the testicles (orchiectomy) for men with advanced prostate cancer. Because of their possible side effects (including blood clots and breast enlargement), estrogens have been replaced by other types of hormone therapy.
Can prostate cancer cause pain in the spine?
Men whose cancer has spread to the bones may have bone pain. Men whose prostate gland has not been removed may have trouble urinating. If the cancer has spread to the spine, even a short-term increase in tumor growth as a result of the flare could press on the spinal cord and cause pain or paralysis.
Is prostate cancer permanent?
It is probably the least expensive and simplest form of hormone therapy. But unlike some of the other treatments, it is permanent, and many men have trouble accepting the remo val of their testicles.
Can you get cancer back after radiation?
Along with radiation therapy as the initial treatment, if you are at higher risk of the cancer coming back after treatment (based on a high Gleason score, high PSA level, and/or growth of the cancer outside the prostate) Before radiation to try to shrink the cancer to make treatment more effective.
Does prostate cancer have a genetic diversity?
Prostate cancer has marked diversity in its biological and clinical features, probably determined by germline and somatic gene alteration as well as gene polymorphisms of the patients.
Is ADT a treatment for prostate cancer?
ADT was recommended as the primary treatment for all patients with metastatic castration-sensitive prostate cancer (mCSPC), irrespective of patient and cancer characteristics, and it was a treatment for “all-comers”.
What is castration-resistant prostate cancer?
As mentioned, CRPC is a type of prostate cancer. It’s estimated that up to 20% of people with prostate cancer have CRPC. CRPC typically develops in men with metastatic (advanced) cancer when their cancer still progresses despite taking hormonal medications.
Which medications treat castration-resistant prostate cancer?
If you have CRPC, your treatment may look a little different than other types of prostate cancer. But specific treatments for CRPC vary by situation.
How effective are these medications?
Medication effectiveness rates for CRPC vary by person. A medication’s exact effectiveness depends on your cancer, its severity, and other medications you’ve tried. It’s hard to predict how well a medication may work.
The bottom line
Prostate cancer is a common cancer for people with prostate glands. Prostate cancer is often treated with hormonal medications. But if you or a loved one has CRPC, other medications may be used. If you’re curious about how well these medications tend to work, please speak with your cancer specialist.
Overview
Chemical castration, sometimes called medical castration, refers to the use of chemicals or drugs to stop sex hormone production. While many people know about this process as a way to stop sex offenders, medical castration is used as a treatment for tumors that feed on sex hormones.
Procedure Details
Before your healthcare provider suggests chemical castration, they’ll need to know if the type of cancer you have is the type that might respond to hormone therapy.
Recovery and Outlook
There’s really no recovery time. You should be able to go back to work or school immediately. You can eat and drink what you like. That’s not to say that you might not have uncomfortable side effects.
When to Call the Doctor
Call your healthcare provider if you have any signs or symptoms that worry you, including existing symptoms that get worse or new symptoms that appear. In most cases, your provider will give you specific things to look out for, but it’s always a good idea to reach out if you have any questions or issues.
Additional Details
Yes, it’s a medical treatment. Chemical castration is used to treat certain forms of cancer. If you’re thinking about chemical castration as a legal option or a criminal consequence, the laws vary by state.
What happens after prostate cancer treatment?
After treatment of prostate cancer, if the prostate-specific antigen (PSA) level remains high or starts rising. In locally advanced prostate cancer, to make external beam radiation therapy more effective in reducing the risk of recurrence. In those with a high risk of recurrence after initial treatment to reduce that risk.
Where is prostate cancer located?
Prostate cancer occurs in the prostate gland, which is located just below the bladder in males and surrounds the top portion of the tube that drains urine from the bladder (urethra). This illustration shows a normal prostate gland and a prostate with a tumor.
Can you get hormone therapy after an orchiectomy?
Orchiectomy is usually performed as an outpatient procedure and doesn't require hospitalization. Typically, no additional hormone therapy is required after orchiectomy.
Can hormone therapy be used for prostate cancer?
Your doctor may recommend hormone therapy for prostate cancer as an option at different times and for different reasons during your cancer treatment. Hormone therapy can be used: In advanced (metastatic) prostate cancer to shrink the cancer and slow the growth of tumors, which also might relieve signs and symptoms.
Does intermittent therapy reduce side effects?
Early research shows this intermittent dosing of hormone therapy medications may reduce the risk of side effects . However, additional studies are needed to determine the long-term survival benefits of intermittent therapy.
Can hormone therapy be adjusted?
Depending on your circumstances, you may undergo tests to monitor your medical situation and watch for cancer recurrence or progression while you're taking hormone therapy. Results of these tests can give your doctor an idea of how you're responding to hormone therapy, and your therapy may be adjusted accordingly.
Does testosterone help prostate cancer?
Most prostate cancer cells rely on testosterone to help them grow. Hormone therapy causes prostate cancer cells to die or to grow more slowly. Hormone therapy for prostate cancer may involve medications or possibly surgery to remove the testicles. Hormone therapy for prostate cancer is also known as androgen deprivation therapy.
Pathophysiology
Treatment
- If your prostate cancer advances and becomes castrate resistant, there are therapies that can help slow the advance of the disease, although they do not cure the cancer. One key goal is keeping the cancer from metastasizing. Metastasizing cancer is cancer that spreads from the prostate gland to more distant parts of the body like the spine, lungs, ...
Diagnosis
- Most prostate cancer today is diagnosed at an early stage when the cancer is still confined to the prostate gland. Men typically have surgery to remove the cancerous prostate gland or radiation treatment to destroy the cancerous cells in the gland.
Causes
- Male sex hormones fuel prostate cancer. The main hormone that drives prostate cancer is testosterone, which is produced in the testicles.
Mechanism
- ADT drastically lowers levels of testosterone and other androgens in the body, and stalls the advance of the cancer in many men but only temporarily. For reasons that remain poorly understood, prostate cancer cells can adapt to lower levels of natural androgens and start to multiply again. The cancer is then said to be castrate resistant.
Mechanism of action
- ADT reduces levels of testosterone and other androgens by 90 to 95 percent. Several different types of ADT medications interfere with or block the processes in the body that control the production of androgens that cause prostate cancer cells to multiply. The drugs are essentially a form of chemical castration. Some drugs are in pill form and others need to be injected anywher…
Results
- After you begin hormone treatment, your doctor will regularly measure levels of prostate-specific antigen (PSA) in your blood. PSA is a protein produced by prostate cancer cells. If PSA levels start to rise while you are on hormone therapy, this can be a sign that the treatment has stopped working and the cancer has become castrate resistant.
Clinical significance
- Another sign that hormone therapy has stopped working is the spread of cancer outside the prostate or the growth of existing tumors.
Research
- Two relatively new hormone therapies have shown promise for castrate-resistant and metastatic prostate cancer. In clinical trials, men lived longer while taking these drugs, even in men previously treated with chemotherapy.
