Bladder is the only common cancer for which women have a worse survival than men Largest gap at one year Some evidence that women are more likely to present with later stage disease Background NORTH WESTERN CANCER REGISTRY Aim of study: To determine why women have a worse prognosis than men: a) Do women present later? b) Is social deprivation a factor?
Resident of Greater Manchester, Lancashire and South Cumbria Muscle-invasive tumour diagnosed in 1998 (MID) No history of bladder cancer Criteria for study subjects NORTH WESTERN CANCER REGISTRY
1190 Patients with bladder tumours identified from North Western Cancer Registry database Pathology reports reviewed to identify those with histologically verified muscle-invasive disease Case notes requested on: (i) Those with histologically verified MID (ii) Those who underwent cystectomy or radiotherapy (iii) Those who died within 3 years of diagnosis 90% reviewed Methods I NORTH WESTERN CANCER REGISTRY
Deaths classified into those due to bladder cancer and to other causes Stage classified into advanced (T4b and/or M1) and non-advanced Deprivation measured using the Townsend Score Methods II NORTH WESTERN CANCER REGISTRY
Statistics Frequency distribution 2 and t-tests Survival Kaplan-Meier Log-Rank test NORTH WESTERN CANCER REGISTRY

Women from more deprived backgrounds present with later stage disease and have a worse prognosis than either men or women from less deprived neighbourhoods. Conclusion NORTH WESTERN CANCER REGISTRY
