Ethnicity in relation to incidence of oesophageal and gastric cancer in England
A partir des données de statistiques hospitalières portant sur la période 2001-2007, cette étude analyse les disparités ethniques dans l'incidence du cancer de l'œsophage et du cancer de l'estomac en Angleterre
Background: This study investigated the variation in incidence of all, and six subgroups of, oesophageal and gastric cancer between ethnic groups. Methods: Data on all oesophageal and gastric cancer patients diagnosed between 2001 and 2007 in England were analysed. Self-assigned ethnicity from the Hospital Episode Statistics dataset was used. Male and female age-standardised incidence rate ratios (IRRs) were calculated for each ethnic group, using White groups as the references. Results: Ethnicity information was available for 83% of patients (76 130/92 205). White men had a higher incidence of oesophageal cancer, with IRR for the other ethnic groups ranging from 0.17 95% confidence interval (CI) (0.15–0.20) (Pakistani men) to 0.58 95% CI (0.50–0.67) (Black Caribbean men). Compared with White women, Bangladeshi women (IRR 2.02 (1.24–3.29)) had a higher incidence of oesophageal cancer. For gastric cancer, Black Caribbean men (1.39 (1.22–1.60)) and women (1.57 (1.28–1.92)) had a higher incidence compared with their White counterparts. In the subgroup analysis, White men had a higher incidence of lower oesophageal and gastric cardia cancer compared with the other ethnic groups studied. Bangladeshi women (3.10 (1.60–6.00)) had a higher incidence of upper and middle oesophageal cancer compared with White women. Conclusion: Substantial ethnic differences in the incidence of oesophageal and gastric cancer were found. Further research into differences in exposures to risk factors between ethnic groups
