Prostate Cancer, Advanced or Metastatic - Significance
Incidence and MortalityProstate cancer is the most common cancer diagnosed in North American men, excluding skin cancers. It is estimated that in 2013, approximately 238,590 new cases and 29,720 prostate cancer-related deaths will occur in the United States. Prostate cancer is now the second leading cause of cancer death in men, exceeded only by lung cancer. It accounts for 28% of all male cancers and 10% of male cancer-related deaths. Age-adjusted incidence rates increased steadily over the past several decades, with particularly dramatic increases associated with the inception of widespread use of prostate-specific antigen (PSA) screening in the late 1980s and early 1990s, followed by a more recent fall in incidence. Age-adjusted mortality rates have recently paralleled incidence rates, with an increase followed by a decrease in the early 1990s. It has been suggested that declines in mortality rates in certain jurisdictions reflect the benefit of PSA screening, but
Prostate Cancer, Advanced or Metastatic - Questions and Answers About Green Tea
What is green tea?Tea has been consumed in Asia since ancient times. Sailors first brought tea to England in the 17th century. Other than water, tea is the most widely consumed beverage in the world. Tea comes from the Camellia sinensis plant. The way the leaves of this plant are processed determines the type of tea produced. Many of the possible health benefits studied in green tea are thought to be from compounds called polyphenols. Polyphenols are a large group of plant chemicals that include catechins (antioxidants that help protect cells from damage caused by free radicals).Catechins make up most of the polyphenols in green tea. The most active catechin in green tea is epigallocatechin-3-gallate (EGCG).To make green tea, the tea leaves are roasted in a wok (or, historically, steamed) to preserve the catechins and retain freshness. Black tea is made using a process that causes the catechins and other compounds in the leaves to oxidize, producing darker colored tea. Oolong tea is
Prostate Cancer, Advanced or Metastatic - Opportunities for Prevention
Hormonal PreventionThe Prostate Cancer Prevention Trial (PCPT), a large randomized placebo-controlled trial of finasteride (an inhibitor of alpha-reductase), was performed in 18,882 men aged 55 years or older. At 7 years, the incidence of prostate cancer was 18.4% in the finasteride group versus 24.4% in the placebo group, a relative risk reduction (RRR) of 24.8% (95% confidence interval [CI], 18.6%–30.6%; P < .001). The finasteride group had more patients with Gleason grade 7 to 10, but the clinical significance of Gleason scoring is uncertain in conditions of androgen deprivation. High-grade cancers were noted in 6.4% of finasteride patients, compared with 5.1% of men receiving a placebo. The increase in high-grade tumors was seen within 1 year of finasteride exposure and did not increase during this time period.Finasteride decreases the risk of prostate cancer but may also alter the detection of disease through effects on prostate-specific

Prostate Cancer, Advanced or Metastatic - Introduction
Men in the United States get prostate cancer more than any other type of cancer except skin cancer. It is found mainly in older men. In the United States, about one out of five men will be diagnosed with prostate cancer. Most men diagnosed with prostate cancer do not die of it.Complementary and alternative medicine (CAM) is a form of treatment used in addition to (complementary) or instead of (alternative) standard treatments. CAM treatments generally are not considered standard medical approaches. Standard treatments go through a long and careful research process to prove they are safe and effective, but less is known about most types of CAM. CAM use among prostate cancer patients is reported to be common. CAM treatments used by prostate cancer patients include certain foods, dietary supplements, herbs, vitamins, and minerals. This PDQ CAM summary gives general information about using foods and dietary supplements to lower the risk of developing prostate cancer or for treating

Prostate Cancer, Advanced or Metastatic - What is screening?
Screening is looking for cancer before a person has any symptoms. This can help find cancer at an early stage. When abnormal tissue or cancer is found early,it may be easier to treat. By the time symptoms appear,cancer may have begun to spread. Scientists are trying to better understand which people are more likely to get certain types of cancer. They also study the things we do and the ...
Prostate Cancer, Advanced or Metastatic - Questions and Answers About Modified Citrus Pectin
What is modified citrus pectin?Pectin is a type of polysaccharide (a carbohydrate with many small sugar molecules that are chemically linked). Pectin is found in the cell walls of most plants and has gel-like qualities that are useful in making many types of food and medicine.Citrus pectin is found in the peel and pulp of citrus fruits such as oranges, grapefruit, lemons, and limes. Citrus pectin can be modified with high pH and heat to break its molecules into smaller pieces. Modified citrus pectin (also called MCP) can be digested and absorbed by the body. How is MCP administered or consumed? MCP may be taken by mouth in powder or capsule form. Have any preclinical (laboratory or animal) studies been conducted using MCP? A study in prostate cancer cells compared 3 different kinds of pectin: citrus pectin, PectaSol (a dietary supplement with MCP), and fractionated pectin powder. Prostate cancer cells treated with the pectin powder had more damage than those treated with citrus pectin
Prostate Cancer, Advanced or Metastatic - Evidence of Benefit
Before the 1990s, the digital rectal examination (DRE) was the test traditionally used for prostate cancer screening. Two other procedures are also available: transrectal ultrasound (TRUS) imaging and serum prostate-specific antigen (PSA) concentrations. Prostate cancer screening is controversial because of the lack of definitive evidence of benefit. A small randomized trial in Sweden evaluated the effects of screening men aged 50 to 69 years every 3 years; the first two screenings included DRE only, followed by two screenings with DRE combined with a test for PSA. The trial was not powered to detect even moderate differences in prostate cancer mortality, which was the same in the two groups: 1.3% (20 of 1,494 patients) for men assigned to screening and 1.3% (97 of 7,532 patients) for controls. The controversy persists. A nested case-control study was conducted at ten U.S. Department of Veterans
Prostate Cancer, Advanced or Metastatic - Changes to This Summary (04 / 11 / 2014)
The PDQ cancer information summaries are reviewed regularly and updated as new information becomes available. This section describes the latest changes made to this summary as of the date above.Treatment Option Overview for Prostate CancerAdded text to state that in a registry of men with rising prostate-specific antigen (PSA) after initial treatment of clinically localized prostate cancer, 19 of 510 men who had undergone radical prostatectomy complained of reduced penile size; however, the data were based upon physician reporting of patients' complaints rather than direct patient questioning or before-and-after measurement of penile length (cited Parekh et al. as reference 51). Added text to state that the use of androgen deprivation therapy may be associated with complaints of penile shortening, although the data are very limited. Also added text to state that in a registry study of men with rising PSA after initial treatment of clinically localized prostate cancer treated with
