title: Ethnic differences in disease presentation of uterine cancer in New Zealand women.
abstract: OBJECTIVE
  Little is known about the ethnic differences in disease presentation of uterine cancer in New Zealand women. The objectives of this study were two-fold: (1) to estimate the incidence and mortality of uterine cancer among women in New Zealand and (2) to examine the association of ethnicity and socioeconomic status with tumour stage and grade, at presentation of uterine cancer.
  
  
  METHODS
  Retrospective survey of cancer cases identified from the New Zealand Cancer Registry. The authors analysed all 3203 uterine cancer cases registered with the New Zealand Cancer Registry during the period 1 January 1997 to 31 December 2006. Ethnic groups were defined based on the self-identified ethnicity recorded on the cancer registry: Ma-ori, Pacific and non-Māori non-Pacific women. Socioeconomic status was categorised as quintiles of the New Zealand Deprivation Index 2006. The mortality to incidence ratio was used as a measure of prognosis. Logistic regression was used to estimate age, ethnic and deprivation adjusted odds ratios (ORs) and 95% confidence intervals (CIs).
  
  
  RESULTS
  Pacific and Māori women have higher incidence (32.4 and 17.7 per 100 000 women, respectively) and mortality rates of uterine cancer (12.1 and 7.4 per 100 000 women, respectively). Women in the most deprived areas are more likely to present with an advanced stage of uterine cancer (OR 1.64, 95% CI 1.09-2.48). Māori and Pacific women are less likely to present with well-differentiated tumours (OR 0.69, 95% CI 0.52-0.92 and OR 0.72, 95% CI 0.52-0.99, respectively).
  
  
  CONCLUSIONS
  Māori and Pacific women, and those from lower socioeconomic areas, are more likely to present with advanced uterine cancer.
