Should the UK lower the age for prostate cancer detection?November 16, 2007Long-term pharmacotherapy for obesity and overweight: updated meta-analysis Should the UK lower the age for prostate cancer detection in line with the USA? Prostate cancer screening occurs in many countries ahead of evidence from ongoing trials. In many countries, early detection (including the UK, when practised), and opportunistic screening commences at 50 years, but a lower age limit has recently been adopted in the USA based on two studies that found elevated prostate specific antigen (PSA) levels in men in their 40s was associated with subsequent prostate cancer. So a team of UK researchers set out to investigate the feasibility of prostate cancer testing, disease prevalence and characteristics in a random group of younger men. Their findings are published on bmj.com today. The study involved 473 men aged 45-49 years randomly selected from eight general practices in one UK city. Of 442 men (34%) who agreed to PSA testing, 54 (12%) had an elevated PSA result. These men were invited for further testing (an ultrasound-guided prostate biopsy, a repeat PSA test, and a digital rectal examination). Ten prostate cancers were detected (a 2.3% detection rate, similar to that in older men). The five men whose tumours were potentially risky to health agreed to have one of three treatment options (radiotherapy, surgery, or active monitoring). This study shows that men younger than 50 years will accept prostate cancer testing, but at a much lower rate than older men, say the authors, so if screening were introduced, greater efforts would be needed to maximize uptake in this age group. If the UK male population aged 45-49 years (2,236,000) were to undergo PSA screening they estimate that 272,905 men would have a raised PSA and of these 51,449 would have prostate cancer. Some of these cancers may benefit from treatment, they say, but this has to be set against the likely distress caused to the 221,456 men with negative biopsy results and the risks of over-treatment and associated side-effects to those diagnosed with cancer. This study will inform the debate about PSA thresholds and age limits only if prostate cancer screening is proven to be effective in ongoing trials, they conclude. Until the results from ongoing trials are available, policy should advocate informed discussion between clinicians and patients about the benefits, potential harms, and limitations of prostate cancer screening, says an accompanying editorial.

Deaths from all cancers in the European Union (EU) between these two periods fell by nine percent in men and eight percent in women, with a large drop among the middle-aged population. Researchers Identify Role of Gene in Tumor Development, Growth and Progression Virginia Commonwealth University Massey Cancer Center and VCU Institute of Molecular Medicine researchers have identified a gene that may play a pivotal role in two processes that are essential for tumor development, growth and progression to metastasis. Common pain relief medication may encourage cancer growth Although morphine has been the gold-standard treatment for postoperative and chronic cancer pain for two centuries, a growing body of evidence is showing that opiate-based painkillers can stimulate the growth and spread of cancer cells. Young athletes need dual screening tests for heart defects, study suggests To best detect early signs of life-threatening heart defects in young athletes, screening programs should include both popular diagnostic tests, not just one of them, according to new research from heart experts at Johns Hopkins. Routine evaluation of prostate size not as effective in cancer screening, Mayo study finds New Mayo Clinic research studied the association between prostate-specific antigen (PSA) levels and prostate size and found that routine annual evaluation of prostate growth is not necessarily a predictor for the development of prostate cancer. Carnegie Mellon researchers link health-care debate to risk of dying in US and Europe The current health care debate in the United States is complicated. Trade-offs between heath care expenditures, lifestyle choices and life expectancy have been suggested but seldom clearly demonstrated. New finding suggests prostate biopsy is not always necessary Researchers at Wake Forest University School of Medicine and the University of Wisconsin-Madison have discovered that some elevated prostate-specific antigen (PSA) levels in men may be caused by a hormone normally occurring in the body, and are not necessarily a predictor of the need for a prostate biopsy. Does prostate-specific antigen velocity help in early detection prostate cancer? The November issue of European Urology, the official journal of the European Association of Urology, features an article focussing on prostate specific antigen (PSA) velocity and early cancer detection. It has been suggested that changes in PSA over time aid prostate cancer detection. New Synthetic Molecules Trigger Immune Response to HIV and Prostate Cancer Researchers at Yale University have developed synthetic molecules capable of enhancing the body's immune response to HIV and HIV-infected cells, as well as to prostate cancer cells. Their findings, published online in the Journal of the American Chemical Society, could lead to novel therapeutic approaches for these diseases. Chemo-radiation before prostate removal may prevent cancer recurrence Researchers in the Oregon Health & Science University Knight Cancer Institute and the Portland Veterans Affairs Medical Center have found a combination of radiation therapy and chemotherapy given before prostate removal is safe and may have the potential to reduce cancer recurrence and improve patient survival.
