Gastric cancer survival (in)equity from 2002 to 2021: examining demographic and clinical characteristics among Māori and non-Māori

Summary:

While gastric cancer mortality risk is still higher for Māori compared with non Māori, this disparity has reduced in recent years, according to a registry study. Records for 1452 Māori and 6402 non-Māori diagnosed with gastric cancer were obtained from the New Zealand Cancer Registry, and linked with mortality data from Statistics New Zealand. Ethnic inequity in gastric cancer mortality was apparent over the period 2002 to 2017, but was smaller in more recent periods, particularly 1-year age-standardised mortality. The mortality difference for Māori compared with non-Māori was most pronounced for those aged 45-64 years.

Comment:
Getting H. pylori testing and treatment right is so important for Māori and Pacific peoples who have higher rates of both H. pylori infection and associated gastric cancer. International research now shows that H. pylori is the single greatest modifiable risk factor for gastric cancer and may carry a greater population-level risk than inherited stomach cancer gene syndromes. Together, these papers demonstrate that inequities in testing, access to treatment, and early intervention are not just issues of infection management, but major contributors to preventable cancer inequities, reinforcing the importance of Māori-led approaches.
