Abstract

Background: This study aimed to examine the incidence and survival of lung cancer patients from several different ethnic groups in a large ethnically diverse population in the United Kingdom.

Methods: Data on residents of South East England diagnosed with lung cancer between 1998 and 2003 were extracted from the Thames Cancer Registry database. Age- and socioeconomic deprivation-standardised incidence rate ratios were calculated for males and females in each ethnic group. Overall survival was examined using Cox regression, adjusted for age, socioeconomic deprivation, stage of disease and treatment. Results are presented for White, Indian, Pakistani, Bangladeshi, Black Caribbean, Black African and Chinese patients, apart from female survival results where only the White, South Asian and Black ethnic groups were analysed.

Results: Compared with other ethnic groups of the same sex, Bangladeshi men, White men and White women had the highest incidence rates. Bangladeshi men had consistently higher survival estimates compared with White men (fully adjusted hazard ratio 0.46; P<0.001). Indian (0.84; P=0.048), Black Caribbean (0.87; P=0.47) and Black African (0.68; P=0.007) men also had higher survival estimates. South Asian (0.73; P=0.006) and Black (0.74; P=0.004) women had higher survival than White women.

Conclusion: Smoking prevention messages need to be targeted for different ethnic groups to ensure no groups are excluded. The apparent better survival of South Asian and Black patients is surprising, and more detailed follow-up studies are needed to verify these results.
