Journal ArticleDOI
Effect of NHS breast screening programme on mortality from breast cancer in England and Wales, 1990-8: comparison of observed with predicted mortality.
TL;DR: Assessment of the impact of the NHS breast screening programme on mortality from breast cancer in women aged 55-69 years over the period 1990-8 found both screening and other factors, including improvements in treatment, had resulted in substantial reductions in mortality.
Journal ArticleDOI

TL;DR: Recall and negative open surgical biopsy rates are twice as high in US settings than in the United Kingdom but cancer detection rates are similar; efforts to improve US mammographic screening should target lowering the recall rate without reducing the cancer detection rate.
Journal ArticleDOI
Colonoscopy quality measures: experience from the NHS Bowel Cancer Screening Programme
Thomas J W Lee,Matthew D. Rutter,Roger G. Blanks,Sue Moss,A. F. Goddard,Andrew Chilton,Claire Nickerson,Richard J. Q. McNally,Julietta Patnick,Colin J Rees +9 more
TL;DR: Quality is achieved by ensuring BCSP colonoscopists meet a high standard before starting screening and through ongoing quality assurance, as demonstrated by high caecal intubation rate, ADR and comfort scores, and low adverse event rates.
Journal ArticleDOI
Risk factors for adverse events related to polypectomy in the english bowel cancer screening programme
Matthew D. Rutter,Matthew D. Rutter,Claire Nickerson,Colin J Rees,Colin J Rees,Julietta Patnick,Roger G. Blanks +6 more
TL;DR: This is the first demonstration of substantial and significantly increased risk for both noteworthy bleeding (requiring transfusion) and perforation from cecal polypectomy for a given polyp size, compared with elsewhere in the colon.
Journal ArticleDOI
Longer mean colonoscopy withdrawal time is associated with increased adenoma detection: evidence from the Bowel Cancer Screening Programme in England
Thomas Lee,Thomas Lee,Roger G. Blanks,Colin J Rees,Colin J Rees,Karen Wright,Claire Nickerson,Sue Moss,Andrew Chilton,A. F. Goddard,Julietta Patnick,Richard J. Q. McNally,Matthew D. Rutter,Matthew D. Rutter +13 more
