Prostate cancer is a malignancy of one of the major male sex glands, in which cells of the prostate become abnormal and start to grow uncontrollably, forming tumors.
Men with wives, significant others more likely to be screened for prostate cancer – Although the link between early screening and prostate cancer survival is well established, men are less likely to go for early screening unless they have a wife or significant other living with them, according to a study published in Cancer Epidemiology, Biomarkers and Prevention, a journal of the American Association for Cancer Research.
One-fifth of men under age 50 reported undergoing a prostate specific antigen (PSA) test to detect prostate cancer in the previous year, yet only one in three young black men reported ever having a PSA test in the previous year. – In one of the first examinations of PSA screening in younger men, a study published by researchers at Duke Medicine’s Prostate Center finds that one-fifth of men under age 50 reported undergoing a prostate specific antigen (PSA) test to detect prostate cancer in the previous year, yet only one in three young black men reported ever having a PSA test in the previous year.
US Preventive Services Task Force updates prostate cancer screening recommendations; Task Force finds no screening benefit for men over 75. – The U.S. Preventive Services Task Force (USPSTF), updating its 2002 report, now recommends against routine prostate cancer screening for men over the age of 75. More evidence is needed to determine if men under 75 could benefit from screening.
Schizophrenia may be partly caused by the effects of unusual structural changes in genes. – People with schizophrenia (mental illness variously affecting behavior, thinking, and emotion) have an increased number of unusual chromosomal changes, particularly structural changes that have the potential to alter the function of the genes.
Eating one or more portions of broccoli every week can reduce the risk of prostate cancer, and the risk of localised cancer becoming more aggressive. – For the first time, a UK research group at the Institute of Food Research led by Professor Richard Mithen has provided an explanation of how eating broccoli might reduce cancer risk based upon studies in men, as opposed to trying to extrapolate from animal models.
Six new genes identified which play a role in the development of type 2 diabetes, and among the group is the second gene known to also play a role in prostate cancer. – Scientists have identified six new genes which play a role in the development of type 2 diabetes, and among the group is the second gene known to also play a role in prostate cancer.
UK researchers identified more than 7 new genetic links to prostate cancer, 2 of which would be included in a new diagnostic test aimed at spotting men at risk from this disease. – 7 new sites in the human genome identified that are linked to men’s risk of developing prostate cancer, revealed by Cancer Research UK funded scientists at the Institute of Cancer Research and University of Cambridge.
$9 million grant from the National Cancer Institute (NCI) awarded to Henry Ford to study the effectiveness of gene therapy to treat prostate cancer. – Henry Ford Hospital is embarking on an expanded major clinical trial involving the use of gene therapy in combination with radiation therapy, to determine if the combined treatment is more effective than radiation therapy alone for patients with intermediate risk prostate cancer.
Environmental health groups call for immediate moratorium on bisphenol A in baby bottles, food and beverage containers. Baby bottles leach toxic chemical, according to new U.S. and Canadian Study. – Dozens of state and national environmental health organizations in the U.S. and Canada are calling for an immediate moratorium on the use of bisphenol A (BPA) in baby bottles and other food and beverage containers, based on the results of a new study that demonstrates the toxic chemical BPA leaches from popular plastic baby bottles when heated.
New, non-invasive prostate cancer test beats PSA in detecting prostate cancer, researchers report. Simple urine test leads to more accurate diagnoses, fewer false-positive results. – An experimental biomarker test developed by researchers at the University of Michigan more accurately detects prostate cancer than any other screening method currently in use, according to a study published in the February 1 issue of Cancer Research, a journal of the American Association for Cancer Research.
Interim analysis supports continuation of Cell Genesys’ VITAL-1 Phase 3 Clinical Trial of GVAX Immunotherapy for Prostate Cancer – Cell Genesys, Inc. (Nasdaq: CEGE) announced that the Independent Data Monitoring Committee (IDMC) for VITAL-1, the first of two ongoing Phase 3 clinical trials of GVAX immunotherapy for prostate cancer, has completed a pre-planned interim analysis and has recommended that the study continue, as GVAX cancer immunotherapy improves prostate cancer patients survival.
Five genetic variants and a family history accounted for almost half (46 percent) of prostate cancer patients. Researchers identified five genetic locations associated with risk of developing prostate cancer: three on chromosome 8q24, one on chromosome 17q12 and one on 17q24.3. – Genetic testing of DNA in a blood sample can determine which men are likely to develop prostate cancer, as five genetic variants previously associated with prostate cancer risk have a strong cumulative effect.
