Is surgery to remove secondary cancer always a good thing?
Publication date: 22 February 2013
In this week’s BMJ (1), Tom Treasure and Martin Utley of UCL’s Clinical Operational Research Unit challenge the utility of repeated surgery for sarcoma which became accepted practice 40 years ago. Sarcoma is the name given to cancers of the structural tissues of the body (bone, muscle, fat) as opposed to organs (breast, lung, prostate). Sarcoma, particularly of bone, tends to affect younger people and if it spreads it tends to be by blood borne seeding in the lungs where the nodules of secondary cancer are called metastases. They can be removed by surgery - an operation called metastasectomy.

CORU's visual outcome monitoring tool (VLAD) goes global!
Publication date: 1 June 2012
Over fifteen years ago, researchers at CORU collaborated with heart surgeons to produce charts that could be used to monitor risk-adjusted outcomes following surgery in a routine manner. These charts are called Variable Life-Adjusted Displays (VLAD) Charts and are now routinely used in cardiac units across the UK and internationally. VLAD Charts have also started to be used to monitor other outcomes, almost always in hospital settings, and almost always in high income contexts. They are most useful for allowing users to quickly spot trends in outcomes that might warrant further investigation or aid understanding of a dataset.

Save the Children launch website designed with CORU's help
Publication date: 17 October 2011
Save the Children have just launched a health financing website (equitablehealthfinancing.org) designed with the help of
Christina Pagel and Martin Utley of CORU and
colleagues at the Centre for International Health and Development. The website
aims to help policy makers in low and middle income countries navigate the
complex evidence around different ways of financing a health system, especially
given the gradual phasing out of fees at point of use. The website uses a
variety of methods to summarise the evidence of a rapid literature review, fully
exploiting web architecture by including cross-referencing and searchable and
sortable tables. Most innovative are new ‘scattar plots' (a combination of scatter and radar) showing a
graphical summary of the evidence of impact for different tools (see also figure)
where the distance of each study (dot) from the centre depends on how closely
the context of that study matches the country of the user.
Attempts at surgical removal are of no benefit to asbestos cancer sufferers finds trial led by CORU's Tom Treasure
Publication date: 25 July 2011
Patients suffering from cancer of the lung cavity do not survive any longer if surgeons remove the lung and cavity linings, compared with those who do not have this major surgery. That is the conclusion of a ten-year series of studies carried out by a team at UCL and the Institute of Cancer Research led by CORU's Tom Treasure.
Pandemic flu countermeasure work published in Vaccine
Publication date: 21 June 2011
CORU's work with the UK Department of Health last year has resulted in a paper1 published in Vaccine. One of the major complications of flu is pneumonia and it was thought that vaccinating the population against pneumococcal pneumonia at the start of a pandemic might prevent deaths due to complications of flu. We built a mathematical model to investigate the potential effect of such a policy using a variety of estimates over the efficacy of the pneumonia vaccine, the virulence of the flu and the achievable coverage of such a vaccination programme. We found that there were substantial reductions in deaths only under specific circumstances - a virulent flu where most complications were due to pneumococcal pneumonia.
CORU's work shows effects of selective citation on surgical practice
Publication date: 16 June 2011
Pulmonary metastasectomy for colorectal cancer is a commonly performed and well-established practice of over 50 years standing. The absence of strong evidence, in the form of controlled studies, to support this practice led three of CORU's researchers to investigate the evidence base that has been used in establishing its status as a standard of care. Using citation network analysis on a total of 344 publications, they found frequent use of historical or landmark papers while, on the other hand, the few papers expressing opposing viewpoints were rarely cited (the four papers outside the main citation network in the figure below). They concluded that this citation pattern tends to escalate belief in clinical practice even when it lacks a high-quality evidence base and helps create an impression of more authority than is warranted.
Editorial praises CORU's simple risk stratification model
