Abstract 2368: Risk factors of pancreatic cancer in Vietnam: A matched case-control hospital-based study

Background: Data about the risk factors and cancer types in developing countries remains limited. We investigate for the first time the role of a number of risk factors (family cancer history, smoking, alcohol consumption, diabetes, hypertension) associated with pancreatic cancer among Vietnamese patients. Methods: Patients hospitalized at 4 hospitals (K, Bach Mai, Viet Duc, Thai Nguyen) and diagnosed with pancreatic cancer (confirmed by histopathology and/or MRI/CT scan) in the period from January 2017 to May 2019 were included in the study. Some risk factors of the patients were collected and compared with a healthy age- and gender-matched (1:1) control group. Results: We have identified 196 patients with diagnosis of pancreatic cancer of which 114 males and 82 females. The average age of the patient at the time of diagnosis was 58.28 years (standard deviation of 12.94, ranging from 25 to 87). A positive family history, smoking and hypertension disease of pancreatic cancer significantly reduced the risk (OR and 95% CI were 0.06 [0.02 - 0.18], 0.53 [0.27 - 1.00], 0.1 [0.04 - 0.25], respectively). A past or present history of diabetes significantly increased the cancer risk (OR = 2.76 [1.34 - 6.05]), especially in female (OR = 5.68 [1.49 - 28.69]). Current alcohol drinkers showed a significantly increased risk of pancreatic cancer (OR = 2.23 [1.20 - 4.25]). Conclusions: Our finding showed that diabetes significantly increased the risk of pancreatic cancer in Vietnam, especially in women. An alcohol intake habit also increased the risk of pancreatic cancer. Further studies are required for fully understood the other risk factors related to this type of cancer. Citation Format: Tu V.
