Guidelines Development Group

The objective of the Guidelines Development Group (GDG) is to develop evidence-based European Guidelines for breast cancer screening and diagnosis for screening and diagnosis.

The GDG will follow the GRADE approach in defining the healthcare question of interest (population of interest, interventions to be compared and patient-relevant outcomes- PICO), synthesizing the evidence and developing the recommendations for the Guidelines. This will be carried out within virtual working environments and in meetings organised every three months. The initial draft documents and the final versions before publication are subject of open calls for feedback launched online.

An external contractor, CCIb –Iberoamerican Cochrane Centre, supports the GDG for their tasks from literature review to drafting of recommendations.

Stephen Duffy

I am a statistician by training, educated at the University of Edinburgh and Imperial College, London. I have worked in the UK, Singapore, France, Sweden and Russia. I am the Director of the Department of Health’s Policy Research Unit in Cancer Awareness, Screening and Early Diagnosis.

For the last three decades, my research has been mainly in cancer epidemiology, prevention and screening. I worked on the pioneering Swedish Two-County Trial of breast cancer screening, on which the UK's national breast screening programme was based.

Since then I have taken a major role in a number of other trials of cancer screening, in breast, colorectal and lung cancer. These include the UK Trial of Flexible Sigmoidoscopy whose results changed national policy within weeks of publication, and the FH01 study of annual mammography in young women at enhanced familial risk of breast cancer, which contributed to the NICE guidelines on breast cancer risk management.
