Stomach cancer is a leading cause of mortality worldwide, accounting for some 650,000 deaths annually. In New Zealand, stomach cancer is a particularly important disease for the indigenous Māori and the Pacific populations, with rates 3-6 times higher than European New Zealanders. Survival from stomach cancer is also worse for Māori. Our work in this area includes identifying the drivers for both the disparities in incidence and survival, including the prevalence and role of H Pylori, and investigating possible interventions to address these drivers.
Ko te mate pukupuku i te puku tētahi o ngā tino take e mate ana te tangata i te ao, arā ko tōna 650,000 tāngata ka mate i ia tau. I Aotearoa, ko te mate pukupuku i te puku tētahi o ngā tino mate e pā ana ki a Ngāi Māori me ngā iwi o te Moana-nui-a-Kiwa, arā, kei te 3-6 tāima te kaha ake o te mate, tērā i te iwi Pākehā. Kei te kino ake hoki ngā tatauranga a Ngāi Māori mō te ora i te mate pukupuku i te puku. Kei te hāngai ā mātau mahi i konei ki te tautohu i ngā take o te ōritenga kore o te pānga atu me te oranga mai, tae atu ki te nui me te wāhi ki te H Pylori, ā, ki te tirotiro i ngā mahi hei aukati atu i ēnei take.
