title: Breast cancer outcomes in South Asian population of West Yorkshire.
abstract: OBJECTIVE
  To examine tumour stage at diagnosis, treatment, patient and provider delays to diagnosis/treatment and survival of South Asian patients with breast cancer in Yorkshire in comparison with the general population.
  
  
  METHODS
  Retrospective study, using Yorkshire Cancer Registry population-based data on breast cancer. Data on 16,879 women with breast cancer diagnosed between 1986 and 1994 was available, of which 120 patients were South Asian. All-cause survival, controlling for age, socio-economic profile, tumour stage and treatment was examined. Effects of ethnicity on tumour stage at diagnosis, treatment, patient and provider delays to diagnosis and treatment were described. Over the period 1986-1994, an increase in the number of registered South Asian patients with breast cancer was observed. South Asian patients were significantly younger at the time of diagnosis and presented with larger primary tumours. They received similar treatment to non-Asian patients, but a higher mastectomy rate was noted. South Asian patients' survival, after controlling for age differences was similar to non-South Asian patients. South Asian patients had a significantly longer patient-related delay between initial symptoms and presentation to GP and a slightly longer provider-related delay in time to diagnosis and treatment. In conclusion, outcomes of breast cancer treatment in South Asian patients were similar to non-Asian patients. Asian patients presented later to their GPs, with larger primary tumours and more frequently had mastectomy.
