Objective The colorectal cancer mortality-to-incidence
ratio (MIR) can reflect healthcare disparities. However, a
similar association has not yet been established between
the MIR of pancreatic cancer and healthcare disparities.
Methods In this study, the incidence and mortality rates
of pancreatic cancer were obtained from the GLOBOCAN
2012 database. The WHO rankings and total expenditures
on health/gross domestic product (e/GDP) were obtained
from a public database. Linear regression was performed
to determine correlations between the variables.
Results 57 countries met the inclusion criteria according
to the data quality. Developed regions (Europe and the
Americas) had high pancreatic cancer incidence and
mortality rates. The MIRs were over 0.90 in all regions.
No significant correlation was found between MIRs and
the WHO rankings, e/GDP or per capita total expenditure
on health for analysis in the 57 countries, indicating no
association between MIRs and cancer care disparities for
pancreatic cancer.
Conclusions The MIR variations for pancreatic cancer do
not correlate with healthcare disparities among countries.
Further investigation is necessary to confirm this
observation with secondary analysis of databases.
