Stomach cancer in Māori

The aims of this project are:

  1. To investigate the importance of known risk factors for stomach cancer in Māori including socioeconomic factors, Helicobacter pylori, obesity, diet, smoking, and alcohol consumption.
  2. To investigate the role of genetic factors and gene-environment interactions (particularly alcohol consumption and specific genetic polymorphisms) on the risk of stomach cancer.
  3. To explore potential risk factors for subtypes of stomach cancer including diffuse gastric cancer.
  4. To record the care and treatment received by patients and examine factors that affect stomach cancer survival.
