The Prostate

The prostate is a gland in a man's reproductive system. It makes and stores seminal fluid, a milky fluid that nourishes sperm. This fluid is released to form part of semen.

The prostate is about the size of a walnut. It is located below the bladder and in front of the rectum. It surrounds the upper part of the urethra, the tube that empties urine from the bladder. If the prostate grows too large, the flow of urine can be slowed or stopped.

To work properly, the prostate needs male hormones (androgens). Male hormones are responsible for male sex characteristics. The main male hormone is testosterone, which is made mainly by the testicles. Some male hormones are produced in small amounts by the adrenal glands.

Understanding the Cancer Process

Cancer is a group of many related diseases. These diseases begin in cells, the body's basic unit of life. Cells have many important functions throughout the body.

Normally, cells grow and divide to form new cells in an orderly way. They perform their functions for a while, and then they die. This process helps keep the body healthy.

Sometimes, however, cells do not die. Instead, they keep dividing and creating new cells that the body does not need. They form a mass of tissue, called a growth or tumor.

Tumors can be benign or malignant:

• Benign tumors are not cancer. They can usually be removed, and in most cases, they do not come back. Cells from benign tumors do not spread to other parts of the body. Most important, benign tumors of the prostate are not a threat to life.

  >Benign prostatic hyperplasia (BPH) is the abnormal growth of benign prostate cells. In BPH, the prostate grows larger and presses against the urethra and bladder, interfering with the normal flow of urine. More than half of the men in the United States between the ages of 60 and 70 and as many as 90 percent between the ages of 70 and 90 have symptoms of BPH. For some men, the symptoms may be severe enough to require treatment.

• Malignant tumors are cancer. Cells in these tumors are abnormal. They divide without control or order, and they do not die. They can invade and damage nearby tissues and organs. Also, cancer cells can break away from a malignant tumor and enter the bloodstream and lymphatic system. This is how cancer spreads from the original (primary) cancer site to form new (secondary) tumors in other organs. The spread of cancer is called metastasis.

When prostate cancer spreads (metastasizes) outside the prostate, cancer cells are often found in nearby lymph nodes. If the cancer has reached these nodes, it means that cancer cells may have spread to other parts of the body -- other lymph nodes and other organs, such as the bones, bladder, or rectum. When cancer spreads from its original location to another part of the body, the new tumor has the same kind of abnormal cells and the same name as the primary tumor. For example, if prostate cancer spreads to the bones, the cancer cells in the new tumor are prostate cancer cells. The disease is metastatic prostate cancer; it is not bone cancer.

Prostate Cancer: Who's at Risk

The causes of prostate cancer are not well understood. Doctors cannot explain why one man gets prostate cancer and another does not.

Researchers are studying factors that may increase the risk of this disease. Studies have found that the following risk factors are associated with prostate cancer:

• Age. In the United States, prostate cancer is found mainly in men over age 55. The average age of patients at the time of diagnosis is 70.

• Family history of prostate cancer. A man's risk for developing prostate cancer is higher if his father or brother has had the disease.

• Race. This disease is much more common in African American men than in white men. It is less common in Asian and American Indian men.

• Diet and dietary factors. Some evidence suggests that a diet high in animal fat may increase the risk of prostate cancer and a diet high in fruits and vegetables may decrease the risk. Studies are in progress to learn whether men can reduce their risk of prostate cancer by taking certain dietary supplements.

Although a few studies suggested that having a vasectomy might increase a man's risk for prostate cancer, most studies do not support this finding. Scientists have studied whether benign prostatic hyperplasia, obesity, lack of exercise, smoking, radiation exposure, or a sexually transmitted virus might increase the risk for prostate cancer. At this time, there is little evidence that these factors contribute to an increased risk.

Detecting Prostate Cancer

A man who has any of the risk factors described in the "Prostate Cancer: Who's at Risk" section may want to ask a doctor whether to begin screening for prostate cancer (even though he does not have any prostate cancer symptoms), what tests to have, and how often to have them. The doctor may suggest either of the tests described below. These tests are used to detect prostate abnormalities, but they cannot show whether abnormalities are cancer or another, less serious condition. The doctor will take the results into account in deciding whether to check the patient further for signs of cancer. The doctor can explain more about each test.

• Digital rectal exam -- the doctor inserts a lubricated, gloved finger into the rectum and feels the prostate through the rectal wall to check for hard or lumpy areas.

• Blood test for prostate-specific antigen (PSA) -- a lab measures the levels of PSA in a blood sample. The level of PSA may rise in men who have prostate cancer, BPH, or infection in the prostate.

Recognizing Prostate Cancer Symptoms

Early prostate cancer often does not cause symptoms. But prostate cancer can cause any of these problems:

• A need to urinate frequently, especially at night;

• Difficulty starting urination or holding back urine;

• Inability to urinate;

• Weak or interrupted flow of urine;

• Painful or burning urination;

• Difficulty in having an erection;

• Painful ejaculation;

• Blood in urine or semen; or

• Frequent pain or stiffness in the lower back, hips, or upper thighs.

Any of these symptoms may be caused by cancer or by other, less serious health problems, such as BPH or an infection. A man who has symptoms like these should see his doctor or a urologist (a doctor who specializes in treating diseases of the genitourinary system).

Diagnosing Prostate Cancer

If a man has symptoms or test results that suggest prostate cancer, his doctor asks about his personal and family medical history, performs a physical exam, and may order laboratory tests. The exams and tests may include a digital rectal exam, a urine test to check for blood or infection, and a blood test to measure PSA. In some cases, the doctor also may check the level of prostatic acid phosphatase (PAP) in the blood, especially if the results of the PSA indicate there might be a problem.

The doctor may order exams to learn more about the cause of the symptoms. These may include:

• Transrectal ultrasonography -- sound waves that cannot be heard by humans (ultrasound) are sent out by a probe inserted into the rectum. The waves bounce off the prostate, and a computer uses the echoes to create a picture called a sonogram.

• Intravenous pyelogram -- a series of x-rays of the organs of the urinary tract.

• Cystoscopy -- a procedure in which a doctor looks into the urethra and bladder through a thin, lighted tube.

Biopsy

If test results suggest that cancer may be present, the man will need to have a biopsy. During a biopsy, the doctor removes tissue samples from the prostate, usually with a needle. A pathologist looks at the tissue under a microscope to check for cancer cells. If cancer is present, the pathologist usually reports the grade of the tumor. The grade tells how much the tumor tissue differs from normal prostate tissue and suggests how fast the tumor is likely to grow. One way of grading prostate cancer, called the Gleason system, uses scores of 2 to 10. Another system uses G1 through G4. Tumors with higher scores or grades are more likely to grow and spread than tumors with lower scores.

If the physical exam and test results do not suggest cancer, the doctor may recommend medicine to reduce the symptoms caused by an enlarged prostate. Surgery is another way to relieve these symptoms. The surgery most often used in such cases is called transurethral resection of the prostate (TURP or TUR). In TURP, an instrument is inserted through the urethra to remove prostate tissue that is pressing against the upper part of the urethra and restricting the flow of urine. (Patients may want to ask whether other procedures might be appropriate.)

Stages of Prostate Cancer

If cancer is found in the prostate, the doctor needs to know the stage, or extent, of the disease. Staging is a careful attempt to find out whether the cancer has spread and, if so, what parts of the body are affected. The doctor may use various blood and imaging tests to learn the stage of the disease. Treatment decisions depend on these findings.

Prostate cancer staging is a complex process. The doctor may describe the stage using a Roman number (I-IV) or a capital letter (A-D). These are the main features of each stage:

• Stage I or Stage A -- The cancer cannot be felt during a rectal exam. It may be found by accident when surgery is done for another reason, usually for BPH. There is no evidence that the cancer has spread outside the prostate.

• Stage II or Stage B -- The tumor involves more tissue within the prostate, it can be felt during a rectal exam, or it is found with a biopsy that is done because of a high PSA level. There is no evidence that the cancer has spread outside the prostate.

• Stage III or Stage C -- The cancer has spread outside the prostate to nearby tissues.

• Stage IV or Stage D -- The cancer has spread to lymph nodes or to other parts of the body.

Treatment for Prostate Cancer -----

Getting a Second Opinion

Decisions about prostate cancer treatment involve many factors. Before making a decision, a man may want to get a second opinion by asking another doctor to review the diagnosis and treatment options. A short delay will not reduce the chance that treatment will be successful. Some health insurance companies require a second opinion; many others will cover a second opinion if the patient requests it. There are a number of ways to find a doctor who can give a second opinion:

• The patient's doctor may be able to recommend a specialist or team of specialists to consult. Doctors who treat prostate cancer are urologists, radiation oncologists, and medical oncologists. Patients may find it helpful to talk to a specialist in each of these areas. Different types of specialists may have different thoughts about how best to manage prostate cancer.

• The Cancer Information Service, at 1-800-4-CANCER, can tell callers about treatment facilities, including cancer centers and other programs supported by the National Cancer Institute.

• People can get the names of doctors from their local medical society, a nearby hospital, or a medical school.

• The Official ABMS Directory of Board Certified Medical Specialists lists doctors' names along with their speciality and their educational background. This resource, produced by the American Board of Medical Specialities (ABMS), is available in most public libraries. The ABMS also has an online service that lists many board-certified physicians (http://www.certifieddoctor.org/).

Preparing for Prostate Cancer Treatment

The doctor develops a treatment plan to fit each man's needs. Treatment for prostate cancer depends on the stage of the disease and the grade of the tumor (which indicates how abnormal the cells look, and how likely they are to grow or spread). Other important factors in planning prostate cancer treatment are the man's age and general health and his feelings about the treatments and their possible side effects.

Many men with prostate cancer want to learn all they can about their disease, their treatment choices, and the possible side effects of treatment, so they can take an active part in decisions about their medical care. Prostate cancer can be managed in a number of ways (with watchful waiting, surgery, radiation therapy, and hormonal therapy). If the doctor recommends watchful waiting, the man's health will be monitored closely, and he will be treated only if prostate cancer symptoms occur or worsen. Patients considering surgery, radiation therapy, or hormonal therapy may want to consult doctors who specialize in these prostate cancer treatments.

The patient and his doctor may want to consider both the benefits and possible side effects of each option, especially the effects on sexual activity and urination, and other concerns about quality of life. Men with prostate cancer may find helpful information in the sections "Methods of Treatment," "Side Effects of Treatment," and "Support for Men with Prostate Cancer." Also, the patient may want to talk with his doctor about taking part in a research study to help determine the best approach or to study new kinds of treatment. "The Promise of Prostate Cancer Research" section has more information about such studies, called clinical trials.

Prostate Cancer Treatment Methods

Treatment for prostate cancer may involve watchful waiting, surgery, radiation therapy, or hormonal therapy. Some patients receive a combination of therapies. In addition, doctors are studying other methods of treatment to find out whether they are effective against this disease. (The "Promise of Cancer Research" section has information about research studies.)

Watchful waiting may be suggested for some men who have prostate cancer that is found at an early stage and appears to be slow growing. Also, watchful waiting may be advised for older men or men with other serious medical problems. For these men, the risks and possible side effects of surgery, radiation therapy, or hormonal therapy may outweigh the possible benefits. Men with early stage prostate cancer are taking part in a study to determine when or whether treatment may be necessary and effective. (See "The Promise of Prostate Cancer Research" section for information about this study.)

Surgery is a common treatment for early stage prostate cancer. The doctor may remove all of the prostate (a type of surgery called radical prostatectomy) or only part of it. In some cases, the doctor can use a new technique known as nerve-sparing surgery. This type of surgery may save the nerves that control erection. However, men with large tumors or tumors that are very close to the nerves may not be able to have this surgery.

The doctor can describe the types of surgery and can discuss and compare their benefits and risks.

• In radical retropubic prostatectomy, the doctor removes the entire prostate and nearby lymph nodes through an incision in the abdomen.

• In radical perineal prostatectomy, the doctor removes the entire prostate through an incision between the scrotum and the anus. Nearby lymph nodes are sometimes removed through a separate incision in the abdomen.

• In transurethral resection of the prostate (TURP), the doctor removes part of the prostate with an instrument that is inserted through the urethra. The cancer is cut from the prostate by electricity passing through a small wire loop on the end of the instrument. This method is used mainly to remove tissue that blocks urine flow.

If the pathologist finds cancer cells in the lymph nodes, it is likely that the disease has spread to other parts of the body. Sometimes, the doctor removes the lymph nodes before doing a prostatectomy. If the prostate cancer has not spread to the lymph nodes, the doctor then removes the prostate. But if cancer has spread to the nodes, the doctor usually does not remove the prostate, but may suggest other treatment.

Radiation therapy (also called radiotherapy) uses high-energy x-rays to kill cancer cells. Like surgery, radiation therapy is local therapy; it can affect cancer cells only in the treated area. In early stage prostate cancer, radiation can be used instead of surgery, or it may be used after surgery to destroy any cancer cells that may remain in the area. In advanced stages, it may be given to relieve pain or other problems.

Radiation may be directed at the body by a machine (external radiation), or it may come from tiny radioactive seeds placed inside or near the tumor (internal or implant radiation, or brachytherapy). Men who receive radioactive seeds alone usually have small tumors. Some men with prostate cancer receive both kinds of radiation therapy.

For external radiation therapy, patients go to the hospital or clinic, usually 5 days a week for several weeks. Patients may stay in the hospital for a short time for implant radiation.

Hormonal therapy keeps cancer cells from getting the male hormones they need to grow. It is called systemic therapy because it can affect cancer cells throughout the body. Systemic therapy is used to treat cancer that has spread. Sometimes this type of therapy is used to try to prevent the cancer from coming back after surgery or radiation treatment.

There are several forms of hormonal therapy:

• Orchiectomy is surgery to remove the testicles, which are the main source of male hormones.

• Drugs known as luteinizing hormone-releasing hormone (LH-RH) agonists can prevent the testicles from producing testosterone. Examples are leuprolide, goserelin, and buserelin.

• Drugs known as antiandrogens can block the action of androgens. Two examples are flutamide and bicalutamide.

• Drugs that can prevent the adrenal glands from making androgens include ketoconazole and aminoglutethimide.

After orchiectomy or treatment with an LH-RH agonist, the body no longer gets testosterone from the testicles. However, the adrenal glands still produce small amounts of male hormones. Sometimes, the patient is also given an antiandrogen, which blocks the effect of any remaining male hormones. This combination of treatments is known as total androgen blockade. Doctors do not know for sure whether total androgen blockade is more effective than orchiectomy or LH-RH agonist alone.

Prostate cancer that has spread to other parts of the body usually can be controlled with hormonal therapy for a period of time, often several years. Eventually, however, most prostate cancers are able to grow with very little or no male hormones. When this happens, hormonal therapy is no longer effective, and the doctor may suggest other forms of treatment that are under study.

Side Effects of Prostate Cancer Treatment

It is hard to limit the effects of treatment so that only cancer cells are removed or destroyed. Because healthy cells and tissues may be damaged, treatment often causes unwanted side effects. Doctors and nurses will explain the possible side effects of prostate cancer treatment.

The side effects of cancer treatment depend mainly on the type and extent of the treatment. Also, each patient reacts differently.

Watchful Waiting

Watchful Waiting involves monitoring the man's health closely and to treat only if prostate cancer symptoms occur or worsen.

Although men who choose watchful waiting avoid the side effects of surgery and radiation, there can be some negative aspects to this choice. Watchful waiting may reduce the chance of controlling the disease before it spreads. Also, older men should keep in mind that it may be harder to manage surgery and radiation therapy as they age.

Some men may decide against watchful waiting because they feel they would be uncomfortable living with an untreated cancer, even one that appears to be growing slowly or not at all. A man who chooses watchful waiting but later becomes concerned or anxious should discuss his feelings with his doctor. A different treatment approach is nearly always available.

Surgery

Patients are often uncomfortable for the first few days after surgery. Their pain usually can be controlled with medicine, and patients should discuss pain relief with the doctor or nurse. The patient will wear a catheter (a tube inserted into the urethra) to drain urine for 10 days to 3 weeks. The nurse or doctor will show the man how to care for the catheter.

It is also common for patients to feel extremely tired or weak for a while. The length of time it takes to recover from an operation varies. Surgery to remove the prostate may cause long-term problems, including rectal injury or urinary incontinence. Some men may have permanent impotence. Nerve-sparing surgery is an attempt to avoid the problem of impotence. When the doctor can use nerve-sparing surgery and the operation is fully successful, impotence may be only temporary. Still, some men who have this procedure may be permanently impotent.

Men who have a prostatectomy no longer produce semen, so they have dry orgasms. Men who wish to father children may consider sperm banking or a sperm retrieval procedure.

Radiation Therapy

Radiation therapy may cause patients to become extremely tired, especially in the later weeks of prostate cancer treatment. Resting is important, but doctors usually encourage men to try to stay as active as they can. Some men may have diarrhea or frequent and uncomfortable urination.

When men with prostate cancer receive external radiation therapy, it is common for the skin in the treated area to become red, dry, and tender. External radiation therapy can also cause hair loss in the treated area. The loss may be temporary or permanent, depending on the dose of radiation.

Both types of radiation therapy may cause impotence in some men, but internal radiation therapy is not as likely as external radiation therapy to damage the nerves that control erection. However, internal radiation therapy may cause temporary incontinence. Long-term side effects from internal radiation therapy are uncommon.

Hormonal Therapy

The side effects of hormonal therapy depend largely on the type of treatment. Orchiectomy and LH-RH agonists often cause side effects such as impotence, hot flashes, and loss of sexual desire. When first taken, an LH-RH agonist may make a patient's symptoms worse for a short time. This temporary problem is called "flare." Gradually, however, the treatment causes a man's testosterone level to fall. Without testosterone, tumor growth slows down and the patient's condition improves. (To prevent flare, the doctor may give the man an antiandrogen for a while along with the LH-RH agonist.)

Antiandrogens can cause nausea, vomiting, diarrhea, or breast growth or tenderness. If used a long time, ketoconazole may cause liver problems, and aminoglutethimide can cause skin rashes. Men who receive total androgen blockade may experience more side effects than men who receive a single method of hormonal therapy. Any method of hormonal therapy that lowers androgen levels can contribute to weakening of the bones in older men.

Followup Care

During and after treatment, the doctor will continue to follow the patient. The doctor will examine the man regularly to be sure that the disease has not returned or progressed, and will decide what other medical care may be needed. Followup exams may include x-rays, scans, and lab tests, such as the PSA blood test.

Support for Men with Prostate Cancer

Living with a serious disease such as cancer is not easy. Some people find they need help coping with the emotional as well as the practical aspects of their disease. Patients often get together in support groups, where they can share what they have learned about coping with their disease and the effects of prostate cancer treatment. Patients may want to talk with a member of their health care team about finding a support group.

People living with cancer may worry about caring for their families, keeping their jobs, or continuing daily activities. Concerns about prostate cancer treatments and managing side effects, hospital stays, and medical bills are also common. Doctors, nurses, dietitians and other members of the health care team can answer questions about treatment, working, or other activities. Meeting with a social worker, counselor, or member of the clergy can be helpful to those who want to talk about their feelings or discuss their concerns. Often, a social worker can suggest resources for help with rehabilitation, emotional support, financial aid, transportation, or home care.

It is natural for a man and his partner to be concerned about the effects of prostate cancer and its treatment on their sexual relationship. They may want to talk with the doctor about possible side effects and whether these are likely to be temporary or permanent. Whatever the outlook, it is usually helpful for patients and their partners to talk about their concerns and help one another find ways to be intimate during and after treatment.

Booklets and other useful materials are available from the Cancer Information Service and through other sources listed in the "Information Resources" section.

The Cancer Information Service can also provide information to help patients and their families locate programs and services.

The Promise of Prostate Cancer Research

Doctors all over the country are conducting many types of clinical trials (research studies) in which people take part voluntarily. These include studies of ways to prevent, detect, diagnose, and treat prostate cancer; studies of the psychological effects of the disease; and studies of ways to improve comfort and quality of life. Research already has led to advances in these areas, and researchers continue to search for more effective approaches.

People who take part in clinical trials have the first chance to benefit from new approaches. They also make important contributions to medical science. Although clinical trials may pose some risks, researchers take very careful steps to protect people who take part.

A man who is interested in being part of a clinical trial should talk with his doctor.

Causes

Although researchers know several risk factors for prostate cancer, they still are not sure why one man develops the disease and another doesn't. (Known risk factors, which include aging, are listed in the "Prostate Cancer: Who's at Risk?" section.)

Some aspects of a man's lifestyle may affect his chances of developing prostate cancer. For example, some evidence suggests a link between diet and this disease. These studies show that prostate cancer is more common in populations that consume a high-fat diet (particularly animal fat), and in populations that have diets lacking certain nutrients. Although it is not known whether a diet low in fat will prevent prostate cancer, a low-fat diet may have many other health benefits.

Some research suggests that high levels of testosterone may increase a man's risk of prostate cancer. The difference between racial groups in prostate cancer risk could be related to high testosterone levels, but it also could result from diet or other lifestyle factors.

Researchers also are looking for changes in genes that may increase the risk for developing prostate cancer. They are studying the genes of men who were diagnosed with prostate cancer at a relatively young age (less than 55 years old) and the genes of families who have several members with the disease. Much more work is needed, however, before scientists can say exactly how changes in these genes are related to prostate cancer. Men with a family history of prostate cancer who are concerned about an inherited risk for this disease should talk with their doctor. The doctor may suggest seeing a health professional trained in genetics.

Prevention

Several studies are under way to explore how prostate cancer might be prevented. These include the use of dietary supplements, such as vitamin E and selenium. In addition, recent studies suggest that a diet that regularly includes tomato-based foods may help protect men from prostate cancer.

The drug finasteride is being studied in the Prostate Cancer Prevention Trial, which involves thousands of men across the country who are participating for 7 years, until 2004.

Scientists are also looking at ways to prevent recurrence among men who have been treated for prostate cancer. These approaches involve the use of drugs such as finasteride, flutamide, and LH-RH agonists. Studies have shown that hormonal therapy after radiation therapy or after radical prostatectomy can benefit certain men whose cancer has spread to nearby tissues.

Researchers also are investigating whether diets that are low in fat and high in soy, fruits, vegetables, and other food products might prevent a recurrence. The Cancer Information Service can provide information about these studies.

Screening/Early Detection

Researchers are studying ways to screen men for prostate cancer (check for the disease in men who have no prostate cancer symptoms). At this time, it is not known whether screening for prostate cancer actually saves lives, even if the disease is found at an earlier stage. The NCI-supported Prostate, Lung, Colorectal, and Ovarian Cancer Screening Trial is designed to show whether certain detection tests can reduce the number of deaths from these cancers. This trial is looking at the usefulness of prostate cancer screening by performing a digital rectal exam and checking the PSA level in the blood in men ages 55 to 74. The results of this trial may change the way men are screened for prostate cancer. The Cancer Information Service can provide information about this trial.

Prostate Cancer Treatment

Through research, doctors try to find new, more effective ways to treat prostate cancer. Many studies of new approaches for men with prostate cancer are under way. When laboratory research shows that a new treatment method has promise, patients receive the new approach in prostate cancer treatment clinical trials. These studies are designed to answer important questions and to find out whether the new approach is safe and effective. Often, clinical trials compare a new treatment with a standard approach.

Cryosurgery is under study as an alternative to surgery and radiation therapy. The doctor tries to avoid damaging healthy tissue by placing an instrument known as a cryoprobe in direct contact with the tumor to freeze it. The extreme cold destroys the cancer cells.

Doctors are studying new ways of using radiation therapy and hormonal therapy. They also are testing the effectiveness of chemotherapy and biological therapy for men whose cancer does not respond or stops responding to hormonal therapy. In addition, scientists are exploring new treatment schedules and new ways of combining various types of treatment. For example, they are studying the usefulness of hormonal therapy before primary therapy (surgery or radiation) to shrink the tumor.

For men with early stage prostate cancer, researchers also are comparing treatment with watchful waiting. The results of this work will help doctors know whether to treat early stage prostate cancer immediately or only later on, if prostate cancer symptoms occur or worsen.

Keeping in tune with your disease or condition not only makes treatment less intimidating but also increases its chance of success, and has been shown to lower a patients risk of complications. As well, as an informed patient, you are better able to discuss your condition and treatment options with your physician.

A new service available to patients provides a convenient means of staying informed, and ensures that the information is both reliable and accurate. If you wish to find out more about HealthNewsflash's innovative service, take the tour.
