Discuss the nurse\u2019s role in helping manage the long-term sequelae experienced by the prostate cancer patient post-treatment.<\/li>\n<\/ul>\n\n\n\n
\n\n\n\nINTRODUCTION<\/h2>\n\n\n\n
Being diagnosed with prostate cancer is difficult to deal with both physically and emotionally. Men respond to the diagnosis in ways that may include feeling angry and fearful. They may be anxious and uncertain regarding treatment options and the impact of treatment side effects. <\/p>\n\n\n\n
Nurses play a pivotal role in helping these patients by listening to and addressing their concerns. They help patients understand what is involved with each treatment option, what the risks and benefits are, what their experience may be during treatment, and what they can expect following treatment. <\/p>\n\n\n\n
Nurses are also a valuable resource and support for helping the prostate cancer patient manage the long-term, post-treatment effects and improve their quality of life.<\/p>\n\n\n\n
\n\n\n\nPROSTATE CANCER OVERVIEW<\/h2>\n\n\n\n
Prostate cancer is usually slow growing and seldom causes symptoms until it enters an advanced stage. Most men who develop prostate cancer die from other causes, and they may even be unaware they have it. However, once the cancer begins to grow quickly or when it spreads beyond the prostate gland, it becomes threatening. Whether and how prostate cancer grows is different from one individual to another, and it is difficult to predict accurately how it will continue to develop in a specific person.<\/p>\n\n\n\n
Types of Prostate Cancer <\/h3>\n\n\n\n
Localized prostate cancer refers to cancer that affects the prostate gland, has not spread to lymph nodes, and has not formed tumors in other areas of the body (metastasis) (IQWiG, 2020).<\/p>\n\n\n\n
There are many types of prostate cancer; adenocarcinoma, <\/strong>diagnosed in 99% of prostate cancer cases, is the most common type (CTCA, 2021a). This type of cancer may occur anywhere in the body and forms in the glandular epithelial cells lining organs that secrete mucus or other fluids. Adenocarcinoma in the prostate is also referred to as glandular prostate cancer<\/em>. There are two main subtypes of adenocarcinoma:<\/p>\n\n\n\n\n- Acinar, a cancer that accounts for practically all prostate adenomas<\/li>\n\n\n\n
- Prostate ductal adenocarcinoma (PDA), a rarer and more aggressive type of adenocarcinoma, which is hard to detect, as it does not always increase PSA (prostate specific antigen) levels<\/li>\n<\/ul>\n\n\n\n
(CTCA, 2021a)<\/p>\n\n\n\n
Other prostate cancers<\/strong> are very rare and include:<\/p>\n\n\n\n\n- Transitional cell carcinoma (or urothelial cancer), which spreads to the prostate from the urethra or bladder<\/li>\n\n\n\n
- Neuroendocrine tumors (carcinoids), which appear in nerve and gland cells that make and release hormones into the bloodstream<\/li>\n\n\n\n
- Small-cell carcinoma, the most aggressive type of neuroendocrine cancer<\/li>\n\n\n\n
- Squamous cell carcinoma, a very rare but fast-growing form that starts in fat cells covering the prostate gland<\/li>\n\n\n\n
- Prostate sarcoma, which develops outside the prostate gland in the soft tissue of the prostate (muscles and nerves)<\/li>\n<\/ul>\n\n\n\n
(CTCA, 2021a)<\/p>\n\n\n\n
Risk Factors for Prostate Cancer <\/h3>\n\n\n\n
The exact cause of prostate cancer is not known, but certain factors are known to increase the risk. These include:<\/p>\n\n\n\n
\n- Age:<\/strong> Age is the greatest risk factor, and prostate cancer risk increases with age. <\/li>\n\n\n\n
- Close relatives with prostate cancer: <\/strong>Having a blood-relative father or brother increases risk, and having several other close relatives with prostate cancer increases risk even higher. <\/li>\n\n\n\n
- Family history of breast cancer: <\/strong>Having a family history of genes that increase the risk of breast cancer or family history of breast cancer raises the risk for prostate cancer.<\/li>\n\n\n\n
- Ethnicity:<\/strong> Black men have a somewhat higher risk.<\/li>\n\n\n\n
- Obesity: <\/strong>Obesity raises the risk of prostate cancer, although studies have shown mixed results. In obese patients, the cancer is more likely to be more aggressive and more likely to return after initial treatment.<\/li>\n\n\n\n
- Vitamin E:<\/strong> Dietary supplements with a high level of vitamin E have been shown to increase risk 17% if taken over many years. No biological mechanism has been proposed to explain the increase.<\/li>\n<\/ul>\n\n\n\n
(OSU, 2021)<\/p>\n\n\n\n
No high-quality studies have been done that show that diet influences risk (IQWiG, 2020; Mayo Clinic, 2021a).<\/p>\n\n\n\n
Prostate Cancer Prevalence<\/h3>\n\n\n\n
Second to skin cancer, prostate cancer is the most common cancer in men. About 1 in 8 (12.5%) men will receive a prostate cancer diagnosis during their lifetime. Prostate cancer is the second leading cause of cancer death in men, second only to lung cancer. About 1 in 4 men will die from it. <\/p>\n\n\n\n
About 6 cases in 10 are diagnosed in men ages 65 or older. Prostate cancer is rarely diagnosed in men under 40. Average age at diagnosis is about 66.<\/p>\n\n\n\n
The percentage of prostate cancers diagnosed at the local stage is 74.3%, and the five-year relative survival for localized prostate cancer is 100.0%. The overall five-year relative survival for those diagnosed with prostate cancer is 97.5% (ACS, 2021a; NCI, 2021).<\/p>\n\n\n\n
Clinical Manifestations<\/h3>\n\n\n\n
In most cases, prostate cancer symptoms are not evident in the early stages. About 85% of prostate cancers are detected during early screening tests before the patient develops any symptoms. The severity of symptoms may depend on where the cancer is located in the prostate and how advanced it has become. <\/p>\n\n\n\n
Due to the proximity of the prostate gland to bladder and urethra, the cancer may produce a variety of symptoms<\/strong>, including:<\/p>\n\n\n\n\n- Urinary frequency and urgency<\/li>\n\n\n\n
- Dysuria<\/li>\n\n\n\n
- Increased urination at night<\/li>\n\n\n\n
- Loss of bladder control<\/li>\n\n\n\n
- Decreased flow or velocity of urine stream<\/li>\n\n\n\n
- Hematuria<\/li>\n\n\n\n
- Hematospermia<\/li>\n\n\n\n
- Erectile dysfunction<\/li>\n<\/ul>\n\n\n\n
Symptoms in the advanced stage<\/strong> may include:<\/p>\n\n\n\n\n- Lymphedema in legs or pelvic area<\/li>\n\n\n\n
- Numbness or pain in hips, legs, or feet<\/li>\n\n\n\n
- Chronic bone pain and fractures<\/li>\n\n\n\n
- Weight loss<\/li>\n\n\n\n
- Uremic symptoms<\/li>\n<\/ul>\n\n\n\n
(CTCA, 2021b; Johns Hopkins Medicine, 2020)<\/p>\n\n\n\n
\n\n\n\nPROSTATE CANCER DIAGNOSIS<\/h2>\n\n\n\n
Accurately diagnosing prostate cancer is crucial in determining which treatment options will be the most effective. <\/p>\n\n\n\n
Early Detection and Screening<\/h3>\n\n\n\n
Most prostate cancers are first found as a result of screening. Two tests commonly used to screen for prostate cancer are:<\/p>\n\n\n\n
\n- Prostate specific antigen (PSA) level (age-adjusted normal range 4.0 to 6.5)<\/li>\n\n\n\n
- Digital rectal examination (DRE)<\/li>\n<\/ul>\n\n\n\n
(Roberts et al., 2018; ACS, 2021b)<\/p>\n\n\n\n
Prostate Cancer Biopsy<\/h3>\n\n\n\n
If prostate cancer is suspected based on results of screening or symptoms, the actual diagnosis can only be made by performing a prostate biopsy. A biopsy involves removing about 12 small core samples of the prostate for histological examination. A core biopsy is the main method used.<\/p>\n\n\n\n
Biopsies can sometimes miss a cancer, and if it is strongly suspected cancer is present after the biopsy, a repeat biopsy may be considered or other lab tests carried out to confirm it. These tests include:<\/p>\n\n\n\n
\n- Prostate Health Index (PHI)<\/li>\n\n\n\n
- 4K Score Test<\/li>\n\n\n\n
- PCA3 (Progensa)<\/li>\n\n\n\n
- ExoDxProstate (IntelliScore)<\/li>\n\n\n\n
- TMPRSS2-ERG<\/li>\n\n\n\n
- ConfirmMDx<\/li>\n<\/ul>\n\n\n\n
(ACS, 2021c)<\/p>\n\n\n\n
Determining the Extent of Cancer<\/h3>\n\n\n\n
To determine if cancer has spread outside of the prostate, imaging tests may be used to provide information about the cancer\u2019s location. Such imaging may include:<\/p>\n\n\n\n
\n- Bone scan<\/li>\n\n\n\n
- CT scan<\/li>\n\n\n\n
- MRI <\/li>\n\n\n\n
- PET-CT scan<\/li>\n<\/ul>\n\n\n\n
(ASCO, 2020a)<\/p>\n\n\n\n
Grading and Staging<\/h3>\n\n\n\n
When cancer is found on biopsy, it is graded using the Gleason scoring system,<\/strong> which indicates how quickly a cancer is growing. The lower the score, the healthier the cells appear. The lowest score for a low-grade cancer is 6. A score of 7 is medium grade, and 8\u201310 are high grade cancers.<\/p>\n\n\n\nStaging indicates how advanced the cancer is. The most common method is the TNM staging system<\/strong>. For instance:<\/p>\n\n\n\n\n- T (tumor) indicates extent of primary tumor.<\/li>\n\n\n\n
- N9 (node) indicates spread to lymph nodes near the bladder.<\/li>\n\n\n\n
- M9 (metastasis) indicates spread to other lymph nodes and organs.<\/li>\n<\/ul>\n\n\n\n
(ASCO, 2021a)<\/p>\n\n\n\n
\n\n\n\nUNDERSTANDING TREATMENT OPTIONS<\/h2>\n\n\n\n
Involvement of patients in treatment decisions is fundamental, enabling them to understand both benefits and risks of available treatment options. Patients must be given information that is clear and understandable to ensure their preferences are based on fact and free of clinician bias. <\/p>\n\n\n\n
Nurses, being patient advocates, are in a unique position to assist prostate cancer patients in making the most appropriate decision for treatment through education and clarification of the evidence supporting each option. Nurses must remain knowledgeable about the following treatment options and be prepared to educate and discuss them with their patients, to support them through their decision-making process, and to provide care during and following their treatment. <\/p>\n\n\n\n
Conservative Treatment for Localized Prostate Cancer<\/h3>\n\n\n\n
Watchful waiting<\/strong> and active surveillance<\/strong> are conservative measures for management of low-risk, low-grade (Gleason score \u22646 and PSA \u226410), stage I and II prostate cancer. These forms of management are based on research that shows many men diagnosed with early-stage, low-grade prostate cancer need little if any immediate medical treatment, especially older men (PCF, 2021a).<\/p>\n\n\n\nIt is important when discussing these forms of treatment with the patient that there is a clear understanding of how the physician defines each approach. Some consider them identical; others consider them as separate management approaches (PCUK, 2019).<\/p>\n\n\n\n
WATCHFUL WAITING BENEFITS AND RISKS<\/h4>\n\n\n\n
Watchful waiting, often called observation,<\/em> is a noninvasive approach that monitors for symptom development. When symptoms occur, treatment is directed toward slowing the disease progression or relieving its symptoms, and not to cure.<\/p>\n\n\n\nThis approach is recommended for men 65 years of age and older who have significant comorbidities and those whose cancer is low-risk and slow-growing. It is also an option for patients with life expectancy of less than 5 years. Its purpose is to avoid the risks and complications associated with more aggressive forms of treatment.<\/p>\n\n\n\n
The benefits<\/strong> of watchful waiting include avoiding aggravation of other health conditions that would be caused by the side effects of aggressive forms of treatment. Watchful waiting avoids overtreatment, maintains the patient\u2019s quality of life, reduces the chance of complications, and treats symptoms as soon as possible. <\/p>\n\n\n\nRisks<\/strong> include the chance that a possibility for a cure may be missed, that characteristics of the cancer will change, and that the cancer will start to grow and metastasize. Living with untreated cancer and its frequent monitoring can also be a source of psychological stress for men (Leslie et al., 2021; Hinkle & Cheever, 2018).<\/p>\n\n\n\nACTIVE SURVEILLANCE BENEFITS AND RISKS<\/h4>\n\n\n\n
Active surveillance for men with prostate cancer involves avoiding or postponing immediate treatment combined with monitoring. Definitive treatment is offered if there is evidence that the patient is at increased risk for disease progression (Richie, 2020). <\/p>\n\n\n\n
Active surveillance is appropriate for men under 65 years of age with a considerable life expectancy (>10 years) and low-risk disease. It involves a monitoring protocol, with the American Society of Clinical Oncology (ASCO, 2020a) recommendations including:<\/p>\n\n\n\n
\n- PSA test every 3 to 6 months<\/li>\n\n\n\n
- DRE every 12 months<\/li>\n\n\n\n
- Confirmatory prostate biopsy within 6 to 12 months<\/li>\n\n\n\n
- Repeat biopsy every 2 to 5 years<\/li>\n\n\n\n
- MRI if clinical or PSA changes of concern arise<\/li>\n<\/ul>\n\n\n\n
Initiation of active treatment is recommended for Gleason scores \u22657 or significant increases in the volume of cancer. Terminating serial biopsies should occur when patients turn 80 years old (Sosnowski et al., 2020). <\/p>\n\n\n\n
The benefits<\/strong> of active surveillance include avoidance of unnecessary treatment and its resultant side effects. Risks<\/strong> are that it can create ongoing worry about having cancer and \u201cdoing nothing\u201d or missing the window of opportunity for curative treatment should the cancer become more aggressive (NFPCSG, 2021).<\/p>\n\n\n\nAggressive Treatments for Prostate Cancer<\/h3>\n\n\n\n
High-risk prostate cancer carries an increased risk of disease recurrence and death. It is treated locally, focally, or systemically. Aggressive treatments increase the potential for definitive cure for localized prostate cancer and for cancer that has spread beyond the prostate. Hormonal therapy, targeted therapy, radiopharmaceuticals, immunotherapy, and chemotherapy are the standard treatments for cancer that has spread beyond the prostate and is no longer considered curable (Leslie et al., 2021; ASCO, 2020b).<\/p>\n\n\n\n
LOCAL TREATMENTS<\/h4>\n\n\n\n
Local treatments affect the cancerous tumor and the area surrounding it. These include surgery and forms of radiation therapy.<\/p>\n\n\n\n
Surgery<\/h5>\n\n\n\n
A radical prostatectomy is the complete removal of the prostate, seminal vesicles, tips of the vas deferens, and often, surrounding fat, lymph nodes, and blood vessels. An attempt is made to protect the nerves that control penile erection and the bladder from damage.<\/p>\n\n\n\n
Radical prostatectomy is the treatment of choice for high-risk localized prostate cancer, offering the benefits<\/strong> of a significant improvement in overall survival, cancer-specific survival, and the development of distant metastases. These benefits over other therapies are not evident before 10 years after treatment and are most pronounced in men younger than 65 years at time of diagnosis (Leslie et al., 2021). <\/p>\n\n\n\nA radical retropubic prostatectomy <\/strong>is performed <\/strong>through an incision in the wall of the lower abdomen under general, spinal, or epidural anesthesia along with sedation. Postoperatively, a urinary catheter remains in place for up to 2 weeks. The operation requires a hospital stay for a few days and limited activities for several weeks.<\/p>\n\n\n\nA radical perineal prostatectomy<\/strong> is done through an incision in the skin of the perineum. This approach is used less often, as it is more likely to lead to erectile dysfunction and because nearby lymph nodes cannot be removed. It is useful for men with other medical conditions that make retropubic surgery difficult. This approach may result in less pain and easier recovery.<\/p>\n\n\n\nA laparoscopic radical prostatectomy (LRP)<\/strong> is done through several smaller incisions. Special surgical tools are used to remove the prostate, one of which has a small video camera on the end for visualization purposes. The surgeon either holds the tools directly or uses a control panel to precisely move robotic arms that hold the surgical tools. This approach has become more common. Rates of major side effects from LRP, however, appear to be about the same as for open prostatectomies. Recovery of bladder control may be slightly delayed with this approach.<\/p>\n\n\n\nTransurethral resection of the prostate (TURP)<\/strong>, the surgery done for benign prostatic hypertrophy, may be recommended for men with advanced prostate cancer to help relieve symptoms, such as difficulty with urination. It is not used as a curative measure, however. During this procedure, under spinal or general anesthesia, the inner part of the prostate gland that surrounds the urethra is removed using a resectoscope passed through the urethra. A laser is used to cut or vaporize the tissue. <\/p>\n\n\n\nRisks<\/strong> of prostate surgery during or shortly after the operation can include:<\/p>\n\n\n\n\n- Adverse reaction to anesthesia<\/li>\n\n\n\n
- Bleeding<\/li>\n\n\n\n
- Blood clots in legs or lungs<\/li>\n\n\n\n
- Infections at surgical site<\/li>\n\n\n\n
- Damage to nearby organs<\/li>\n<\/ul>\n\n\n\n
Rarely, the intestines may be injured, leading to possible abdominal infections that may require reparative surgery. Injuries are more common with laparoscopic and robotic surgery than with the open approach (Leslie et al., 2021; ACS, 2019a).<\/p>\n\n\n\n
Side effects of surgery may include erectile dysfunction, which may occur immediately and improve over time, urinary incontinence, urethral strictures, and an increased risk of inguinal hernias (Leslie et al., 2021). <\/p>\n\n\n\n
Radiation Therapy<\/h5>\n\n\n\n
Radiation therapy involves destroying cancer cells using high-energy rays or particles. Cure rates with radiation are comparable to those of radical prostatectomy. Two major forms of radiation therapy are external beam radiation (EBRT) and brachytherapy (internal radiation). External beam radiation is used as initial treatment for high-risk localized cancer, and brachytherapy is an option for patients with low- or intermediate-risk prostate cancer. <\/p>\n\n\n\n
External beam radiation<\/strong> involves focusing high-energy beams, such as X-rays or protons, directly at the prostate from a machine outside the body, called a linear accelerator.<\/em> It can be used to attempt a cure in an early-stage cancer or to help relieve symptoms, such as bone pain. <\/p>\n\n\n\nBrachytherapy<\/strong> is a type of radiation therapy that can be given as either high-dose-rate or low-dose-rate. With high-dose-rate brachytherapy, radioactive material is temporarily placed in the body for a short period (from a few minutes up to 20 minutes); this may be repeated once or twice a day over a number of days or weeks. Low-dose-rate seed brachytherapy involves placing 80 to 100 radioactive metallic seeds permanently inside the prostate gland. These seeds slowly deliver a high dose of radiation to the gland and seminal vesicles over several months before the radiation completely decays. Brachytherapy can be given by itself or along with external beam radiation.<\/p>\n\n\n\nDepending on the stage of the prostate cancer and other factors, indications<\/strong> for radiation therapy include:<\/p>\n\n\n\n\n- As initial treatment for high-risk localized cancer, resulting in cure rates that are approximately the same as for radical prostatectomy<\/li>\n\n\n\n
- As part of the first treatment (along with hormone therapy) for cancers that have spread into nearby tissues<\/li>\n\n\n\n
- If the cancer is not removed completely or recurs in the area of the prostate post surgery<\/li>\n\n\n\n
- To help keep advanced cancer under control and to prevent or relieve symptoms<\/li>\n<\/ul>\n\n\n\n
Side effects<\/strong> of radiation include:<\/p>\n\n\n\n\n- Radiation proctitis, which can cause bowel dysfunction, including diarrhea, blood in the stool, rectal leakage, and rectal fistula<\/li>\n\n\n\n
- Radiation cystitis, which causes frequency, burning on urination, and\/or hematuria. These usually improve over time, but in some men it is permanent. The U.S. Food and Drug Administration (FDA) has approved a device called a SpaceOAR<\/em> that places a hydrogel between the prostate and the rectum to physically separate those two structures, thereby reducing the dose of radiation delivered to the rectum.<\/li>\n\n\n\n
- Seed migration (with brachytherapy)<\/li>\n\n\n\n
- Urinary incontinence, but less often than with surgery. The risk is low at first, but increases each year for several years after.<\/li>\n\n\n\n
- Rarely, urethral stricture requiring further treatment<\/li>\n\n\n\n
- Erectile dysfunction, including impotence<\/li>\n\n\n\n
- Skin reactions<\/li>\n\n\n\n
- Fatigue<\/li>\n\n\n\n
- Reduced blood counts<\/li>\n\n\n\n
- Pubic hair loss<\/li>\n<\/ul>\n\n\n\n
The benefits <\/strong>of having brachytherapy include avoiding the risks of major surgery, and because brachytherapy is delivered with a high degree of accuracy, it has minimal side effects<\/strong>, especially sexual dysfunction. Preserving sexual function for as long as possible is what men may value the most. Opting for radiation rather than surgery may help avoid erection problems (ACS, 2021d; UM, 2021; Hall et al., 2021). <\/p>\n\n\n\nFOCAL TREATMENTS<\/h4>\n\n\n\n
Focal treatmentsare noninvasive techniques using heat or cold to target small low- or intermediate-risk tumors inside the prostate. The goal of the treatment is to ablate, or destroy, the tumor and a safety margin within the prostate while leaving the remainder of the gland intact. Focal treatments can also be an option for men whose cancer has returned after other treatments. <\/p>\n\n\n\n
Cryotherapy<\/h5>\n\n\n\n
Cryotherapy, also called cryosurgery<\/em> or cryoablation<\/em>, is a focal treatment that uses very cold temperatures to freeze and kill prostate cancer cells as well as most of the prostate gland. Compared to surgery or radiation therapy, long-term effectiveness of cryotherapy is not well known.<\/p>\n\n\n\nCryotherapy treatment is indicated<\/strong> for a cancer that has recurred following other forms of treatment such as radiation therapy. It is an option for men with large prostate glands, for treating low-risk early-stage prostate cancer, or for a man who is not a candidate for surgery or radiation. In most cases, cryotherapy is not used as the initial treatment for prostate cancer.<\/p>\n\n\n\nCryotherapy is done under spinal, epidural, or general anesthesia, and for most patients, it is a <\/p>\n\n\n\n
same-day procedure. During this treatment, a transrectal ultrasound (TRUS) is used to guide several hollow needles through the skin of the perineum, and very cold gases are then passed through the needles to freeze and destroy the prostate. Warm saltwater is passed through a catheter placed in the urethra during the procedure to keep it from freezing. This catheter remains in place for several weeks during recovery.<\/p>\n\n\n\n
Side effects<\/strong> tend to be worse in men who have already had radiation therapy compared to those who have it as initial treatment, and may include:<\/p>\n\n\n\n\n- Hematuria for a day or two following the procedure<\/li>\n\n\n\n
- Soreness in the needle insertion sites<\/li>\n\n\n\n
- Swelling of the penis or scrotum <\/li>\n\n\n\n
- Pain or burning sensation in the bladder and rectum <\/li>\n\n\n\n
- Bladder and bowel frequency (most individuals recover normal function over time)<\/li>\n\n\n\n
- Damage to nerves near the prostate that control erections (erectile dysfunction is more common following cryotherapy than after radical prostatectomy)<\/li>\n\n\n\n
- Urinary incontinence (rare for those who have cryotherapy as initial treatment but more common in those who have already had radiation therapy)<\/li>\n\n\n\n
- Development of a fistula between rectum and bladder (a rare [<1%] but serious occurrence that allows urine to leak into the rectum, often requiring surgical repair) (ACS, 2021e)<\/li>\n<\/ul>\n\n\n\n
Cryotherapy has several benefits <\/strong>over other forms of treatment, including:<\/p>\n\n\n\n\n- Performed on an outpatient basis, with half of all patients going home the same day and half the next day<\/li>\n\n\n\n
- Less blood loss<\/li>\n\n\n\n
- Reported success rates similar to surgery and brachytherapy<\/li>\n\n\n\n
- Quick patient recovery, return to normal activities in about 10 days<\/li>\n\n\n\n
- Minimal pain, which can be treated with anti-inflammatory medications for several days; narcotic pain medications not needed<\/li>\n\n\n\n
- Lower risk over surgery and radiation of incontinence, irritable bladder, and bowel problems<\/li>\n\n\n\n
- Can be repeated if prostate cancer recurs (SHS, 2021)<\/li>\n<\/ul>\n\n\n\n
High-Intensity Focused Ultrasound<\/h5>\n\n\n\n
High-intensity focused ultrasound (HIFU) is a heat-based type of focal therapy in which sound waves are directed at cancerous parts of the prostate gland via a probe inserted into the rectum. HIFU causes the temperature of the tissue to rise, and the heat destroys the targeted tissue area. It is an alternative to active surveillance for patients with early-stage prostate cancer and an alternative or follow-up to radiation, surgery, or other failed treatment for tumors that are small and localized. <\/p>\n\n\n\n
Benefits<\/strong> include:<\/p>\n\n\n\n\n- Requires no surgical incisions and does not use radiation<\/li>\n\n\n\n
- Can target cancer cell tissue, leaving nontargeted tissue unharmed<\/li>\n\n\n\n
- Is an outpatient procedure with short recovery time (within 24 hours)<\/li>\n\n\n\n
- Reduces (but does not eliminate) the risk of urinary incontinence and erectile dysfunction compared to surgery or radiation therapy<\/li>\n<\/ul>\n\n\n\n
HIFU is associated with fewer side effects<\/strong> compared to more aggressive therapies and may include: <\/p>\n\n\n\n
