BACKGROUND Cancer survival is a key measure of the effectiveness of health-care systems. Persistent regional and international differences in survival represent many avoidable deaths. Differences in survival have prompted or guided cancer control strategies. This is the first study in a programme to investigate international survival disparities, with the(More)

METHODS Survey of staff and primary care patients in five ED in New South Wales, Australia using questionnaire based on reasons identified in published studies. RESULTS Clinicians in the survey(More)
In a historical cohort study of all singleton live births in Northern Ireland from 1971-86 (n=434,933) associations between early life factors and childhood acute lymphoblastic leukaemia were investigated. Multivariable analyses showed a positive association between high paternal age (> or =35 years) and acute lymphoblastic leukaemia (relative risk=1.49;(More)
BACKGROUND We investigate whether differences in breast cancer survival in six high-income countries can be explained by differences in stage at diagnosis using routine data from population-based cancer registries. METHODS We analysed the data on 257,362 women diagnosed with breast cancer during 2000-7 and registered in 13 population-based cancer(More)
BACKGROUND Breast cancer mortality is declining in many Western countries. If mammography screening contributed to decreases in mortality, then decreases in advanced breast cancer incidence should also be noticeable. PATIENTS AND METHODS We assessed incidence trends of advanced breast cancer in areas where mammography screening is practiced for at least 7(More)
Among all 14,500 incident cases of basal cell carcinoma (BCC), 6405 squamous cell carcinomas (SCC) and 1839 melanomas reported to the Northern Ireland Cancer Registry between 1993 and 2002, compared with the general population, risk of new primaries after BCC or SCC was increased by 9 and 57%, respectively. The subsequent risk of cancer, overall, was more(More)
Using population-based linked birth and cancer registry data, we investigated whether the risk of brain tumour in childhood (n=155) was associated with perinatal risk factors. This population-based cohort showed that being born into a larger family or to a mother with a history of miscarriage may increase childhood brain tumour risk.
This paper provides local data on the provision of services for patients diagnosed with ovarian cancer in 1996 prior to the reorganisation of cancer services. It documents a service for 140 patients provided by 80 consultant teams and illustrates the need for reorganisation to meet the evidence base already in existence for improvement in survival and will(More)
EDITOR—The 1998 Data Protection Act and the General Medical Council's guidance on confidentiality have resulted in uncertainty about whether patient consent is necessary to fulfil statutory requirements for fair and lawful processing of personal data such as the identifiable health information collected by cancer registries. 1 2 A regulation is expected(More)
