Chronic pancreatitis as a driving factor for pancreatic cancer: An epidemiological understanding.

The retrospective study by Lew et al (2022) examined the rising hospitalization rates for chronic pancreatitis (CP) and its association with pancreatic ductal adenocarcinoma (PDAC), revealing significant ethno-racial disparities and risk factors. Overweight black men aged 40-59 years and white men over 40 years with higher incomes showed an elevated risk of PDAC among CP patients. The study, which included 14.2 million admissions from 2016-2017, found that 2.6% of adult patients were diagnosed with CP, with white males being the majority. Multivariate regression analysis identified men, black individuals, those aged 40-59 years, and individuals with a body mass index (BMI) between 25 and 29.9 as having an increased risk for CP. Moreover, 0.78% of CP patients also had PDAC, with older age and BMI being significant risk factors for developing PDAC in CP patients. The study also highlighted disparities in healthcare access and utilization among different socioeconomic and ethno-racial groups, which may impact the risk and outcomes of CP and PDAC.
