Research at the University of Bristol (UoB) led to the Department of Health (DH) decision in 1997 that screening for prostate cancer would not be introduced in the UK until there was evidence that benefits outweighed harms. UoB-led and collaborative research subsequently provided evidence to support informed decision-making in the NHS. A formal review by the DH in 2010 endorsed the policy and confirmed that any change would be based on evidence from the team's randomised trials. This research has ensured UK men have avoided known harms of prostate cancer screening in the context of uncertain benefits, and saved the UK economy £ billions.
Research carried out at King's College London (KCL) has raised awareness of the potential risks associated with certain hormone therapies used to treat prostate cancer. The group found that such hormone therapy can raise the risk of heart attack by 24% and the risk of dying from heart disease by 21%. However, for men receiving anti-androgen hormone therapy, the risk of dying from heart disease was lower compared to other hormone therapies such as gonadotropin-releasing hormone agonists. With anti-androgen hormone therapy there was a chance of heart failure but the risk was 5% compared to 34% for other hormone therapies which reduce testosterone production.
The research has had very considerable impact in terms of reach, as over 600 articles have been published in newspapers and other media which refer to the KCL finding that men with prostate cancer treated with certain hormone therapies have a higher risk of heart disease and strokes.
The findings had a very significant impact on US Food and Drug Administration (FDA) advice to healthcare professionals on the benefits and risks of hormone therapy. The FDA also required manufacturers of certain hormone therapy drugs to add safety information to labels.
Men with penile cancer often feel very isolated as they are reluctant to talk to others about their condition, and as it is so rare, they do not encounter others who have experienced it. Branney and colleagues' work has produced a resource, available through the Health Talk Online website, for men and their families: http://www.healthtalkonline.org/Cancer/Penile_Cancer.
Men with penile cancer are routinely signposted to this resource. An exhibition of the project's findings has helped to raise awareness of the condition in the general public. By increasing patient information support, clinician insight and men's awareness of the condition, this research has improved the quality of life of men with penile cancer.
A novel test for prostate cancer was developed from research in mitochondrial genetics conducted at Newcastle University. The Prostate Core Mitomic Test was the first of its kind and is now commercially available in North America. It provides molecular evidence to confirm conventional pathology results showing that men identified as being at risk of prostate cancer are, at the time of examination, free of disease. This is an important patient benefit, as conventional pathology has a 30% chance of missing prostate cancer. The Mitomic test obviates the short-term need for a follow-up biopsy, which is an invasive and very uncomfortable procedure. It is also capable of identifying some men at high risk of having prostate cancer that conventional pathology would miss. The test was introduced to the American market in June 2011 and has generated a multi-million dollar investment and turnover.
Bangor University staff (Neal & Wilkinson) are core members of a collaboration whose research since 2003 has had significant policy relevance and impact in the field of primary care oncology. Impact has been made in three areas:
Improvements in therapy have increased the 5-year survival rate for a number of cancers, leading to a new focus on promoting the health and wellbeing of cancer survivors. In the UK alone, over 500,000 people have physical or psychological consequences associated with cancer or its treatment.
Research at the University of Surrey has led to the development of self-management interventions for cancer survivors, demonstrating that active patient involvement leads to significant health and wellbeing benefits. These studies have driven national and international practice policy in the management of the consequences of cancer and its treatment.
Abiraterone (trade name Zytiga) was designed, synthesised and developed by a multidisciplinary team of academic chemists, biologists and clinicians at The Institute of Cancer Research (ICR). Following ICR-led phase I, II and III clinical trials, which demonstrated prolonged survival and improved quality of life for patients with castration-resistant prostate cancer (following cytotoxic therapy), abiraterone was granted approval by the FDA, EMA and NICE. In 2011-2012, abiraterone worldwide sales reached $2.755 billion. In 2012-13, FDA and EMA approval was extended to use in the treatment of metastatic castration-resistant prostate cancer in men who have not received standard chemotherapy.
Thousands of people across the world with a genetic predisposition (HNPCC) to bowel cancer, together with the population at large, have benefited from research on aspirin and dietary fibre undertaken at the University of Bristol since 1993. Clinical trials involving the Bristol group show that the incidence of bowel cancer has fallen in HNPCC patients who take aspirin. Moreover, aspirin use after diagnosis of bowel cancer has reduced colorectal cancer mortality. Furthermore, a high fibre diet also lowers the risk of bowel cancer. These studies led to national public health initiatives (such as the `five-a-day' campaign) that have been instrumental in increasing public awareness of the importance of aspirin and dietary fibre in reducing the risk of bowel cancer, and in establishing international guidelines on dietary advice.
Research within the Northern Ireland Barrett's oesophagus Register demonstrated that cancer risk in this disease was substantially lower than previously thought. It identified clinico-pathological characteristics and potential biomarkers that allow Barrett's patients to be stratified into those with higher and lower cancer risk. This research has influenced recommendations from Gastroenterological Associations in the UK and USA and resulted in altered clinical practice nationally and internationally, in which costly routine endoscopic surveillance is now targeted to Barrett's oesophagus patients with the highest cancer risk.
The Nottingham Bowel Cancer Screening trial showed that biennial Faecal Occult Blood testing reduced bowel cancer mortality by 16%. As a consequence of this trial, the Department of Health launched two screening pilots and introduced a National Bowel Cancer Screening Programme (NBCSP), achieving national coverage in 2010. Since 2008, this has sent out almost 18 million invitations and detected 16,000 bowel cancers, of which 21.6% were early cancers with a 95% chance of cure. It is estimated that the NBCSP saves around 3,500 lives each year in the UK. International screening programmes modelled on the UK system will save many more.
