Unequal impact: Mäori and non-Mäori cancer statistics

Summary:

This comprehensive report from the Ministry of Health details cancer findings, including disparities in incidence and outcomes between Mäori and non-Mäori for the period 1996 to 2001. Mäori ethnicity was classified using the ‘ever Mäori’ approach. Mäori were 18% more likely to be diagnosed with cancer than non-Mäori, and were almost twice as likely to die from their illness. Mäori were less likely to have their cancer stage recorded at diagnosis, and with regard to breast, lung, colon, rectum, cervix, prostate, testis, kidney, oral cancers and melanoma were more likely to be diagnosed at a later stage of the illness. The only cancer which was detected earlier in Mäori was stomach cancer. In general, Mäori have lower rates of survival for cancers. Some, but not all of this disparity may be related to the later detection of the cancers. In conclusion, the report finds; “the existence of stark disparities in experiences and outcomes of cancer between Mäori and non-Mäori” which indicates the need for “urgent and committed action” to address these issues.

Comment:
The Cancer Chart book provides comprehensive and detailed information on cancer among Mäori. The findings raise interesting questions about the quality of care along the entire cancer care pathway for Mäori: from prevention through diagnosis, staging and treatment. For example, Mäori have a lower likelihood of having their stage of cancer at diagnosis recorded. Why? And does this impact on treatment options for Mäori with cancer? Other issues not covered in the document but of equal importance to Mäori include participation in cancer research (often providing new treatments and technologies), whanau ora (support for whanau, financial burden of caring for someone with cancer and changing roles within the whanau) and palliative care. Disparities in experiences and outcomes of cancer between Mäori and non Mäori exist, the greatest impact being on Mäori individuals and communities. Urgent and committed action is necessary to address the issues raised by the researchers.
