Patterns of presentation among New Zealand Maori with pancreatic cancer at Lakes District Health Board.

e18553 Background: New Zealand (NZ) Māori have higher rates of pancreatic cancer than other ethnic groups in NZ. Lakes District Health board (LDHB) has one of the highest proportion of Māori patients within New Zealand, 34.7% compared to 15.7% nationally. We aimed to review the patterns of presentation of patients diagnosed with pancreatic cancer at LDHB between ethnicities. Methods: Patients diagnosed with pancreatic cancer at LDHB between 01 Jul 2014 to 31 Mar 2020 were identified using the faster cancer treatment data and regional hospice referral data. This was cross checked against surgical and oncology referrals. Electronic notes were reviewed to collect data on ethnicity, patient demographics, & presentation. Results: 69 patients were identified; 25 Māori patients and 44 New Zealand European (NZE) patients. The mean age at diagnosis was 63.4 years for Māori and 73.4 years for NZE patients. 22 (88%) Māori patients were below the age of 75 at diagnosis compared to 24 (55%) NZE patients. In both groups there were more affected males than females. Risk factors such as positive smoking history, obesity and diabetes were more prevalent in Māori patients (80% v 43%, 40% v 16%, 44% v 20% respectively). Māori were more likely to present with metastatic disease compared to non-Māori at presentation (64% v 52%). Conclusions: Māori pancreatic cancer patients in our region were more likely to present younger with metabolic syndrome and more advanced disease compared to NZE patients.
