Breast cancer survival in South Asian women in England and Wales

Abstract

Study objectives: To estimate ethnic and socioeconomic differences in breast cancer incidence and survival between South Asians and non-South Asians in England and Wales, and to provide a baseline for surveillance of cancer survival in South Asians, the largest ethnic minority.

Setting: 115 712 women diagnosed with first primary invasive breast cancer in England and Wales during 1986–90 and followed up to 1995.

Methods/design: Ethnic group was ascribed by a computer algorithm on the basis of the name. Incidence rates were derived from 1991 census population denominators for each ethnic group. One and five year relative survival rates were estimated by age, quintile of material deprivation, and ethnic group, using national mortality rates to estimate expected survival.

Main results: Age standardised incidence was 29% lower among South Asian women (40.5 per 100 000 per year) than among all other women (57.4 per 100 000). Five year age standardised relative survival was 70.3% (95%CI 65.2 to 75.4) for South Asian women and 66.7% (66.4 to 67.0) for other women. For both ethnic groups, survival was 8%–9% higher for women in the most affluent group than those in the most deprived group. In each deprivation category, however, survival was 3%–8% higher for South Asian women than other women.

Conclusions: This national study confirms that breast cancer incidence is substantially lower in South Asians than other women in England and Wales. It also provides some evidence that South Asian women diagnosed up to 1990 had higher breast cancer survival than other women in England and Wales, both overall and in each category of deprivation.
