BackgroundThe mortality-to-incidence ratio (MIR) is a marker that reflects the clinical outcome of cancer treatment. MIR as a prognostic marker is more accessible when compared with long-term follow-up survival surveys. Theoretically, countries with good health care systems would have favorable outcomes for cancer; however, no report has yet demonstrated an association between gallbladder cancer MIR and the World's Health System ranking.MethodsWe used linear regression to analyze the correlation of MIRs with the World Health Organization (WHO) rankings and total expenditures on health/gross domestic product (e/GDP) in 57 countries selected according to the data quality.ResultsThe results showed high crude rates of incidence/mortality but low MIR in more developed regions. Among continents, Europe had the highest crude rates of incidence/mortality, whereas the highest age-standardized rates (ASR) of incidence/mortality were in Asia. The MIR was lowest in North America and highest in Africa (0.40 and 1.00, respectively). Furthermore, favorable MIRs were correlated with good WHO rankings and high e/GDP (p=0.01 and p=0.030, respectively).ConclusionsThe MIR variation for gallbladder cancer is therefore associated with the ranking of the health system and the expenditure on health.

Objective Health expenditure is a marker associated with an advanced healthcare system, which contributes toward the good prognosis of patients. Mortality-to-incidence ratios (MIRs) are one of the predictors that reflect the prognosis of cancer patients. There remains some uncertainty on the correlation of MIRs of liver cancer with the health expenditure of countries. Methods We therefore analyzed the correlation of MIRs from the GLOBOCAN 2012 database with the WHO rankings and the total expenditures on health/gross domestic product from WHO by linear regression analyses. A total of 29 countries were selected in this study according to the data quality and the incidence number. Results The results showed high rates of incidence/mortality and MIRs in less developed regions (0.92 vs. 0.96 for more vs. less developed regions). Among the continents, Asia has the highest incidence/mortality in case number, crude rate, and age-standardized rate. In terms of the MIR, Northern America has the lowest MIR and Latin America and the Caribbean have the highest MIRs (0.82 and 1.04, respectively). Finally, favorable MIRs are associated significantly with good WHO ranking and high expenditures on gross domestic product (P = 0.048 and 0.025, respectively). Conclusion The MIR variation for liver cancer is thus found to be associated with the health expenditure and WHO ranking. Copyright (C) 2017 Wolters Kluwer Health, Inc. All rights reserved.

AIM To evaluate the association between mortality-to- incidence ratios (MIRs) and health disparities. METHODS In this study, we used the GLOBOCAN 2012 database to obtain the cancer incidence and mortality data for 57 countries, and combined this information with the World Health Organization (WHO) rankings and total expenditures on health/gross domestic product (e/GDP). The associations between variables and MIRs were analyzed by linear regression analyses and the 57 countries were selected according to their data quality. RESULTS The more developed regions showed high gastric cancer incidence and mortality crude rates, but lower MIR values than the less developed regions (0.64 vs 0.80, respectively). Among six continents, Oceania had the lowest (0.60) and Africa had the highest (0.91) MIR. A good WHO ranking and a high e/GDP were significantly associated with low MIRs (p = 0.001 and p = 0.001, respectively). CONCLUSION The MIR variation for gastric cancer would predict regional health disparities.
