Abstract Background: The incidence rate of lip and oral cancer is increasing in recent years, the prognosis of which is associated with a country’s socioeconomic status. The mortality-to-incidence ratio (MIR) is a reasonable indicator of disparities in cancer screening and treatment. We aim to understand the association between economic status and cancer prognosis.Methods: Data were obtained from the Global Cancer Observatory (GLOBOCAN) and the World Health Organization (WHO). The MIR was applied to evaluate the correlation to healthcare expenditures and the human development index (HDI) disparities via Spearman's rank correlation coefficient.Results: The results showed that Asia has the most cases and deaths. The association of the HDI, current health expenditure (CHE), and ratio of CHE to the percentage of gross domestic product (CHE/GDP) to the crude rate (CR) of incidence show significant results (p<0.001, p=0.005, and p<0.001, respectively). However, their association with the mortality rate (p=0.303, p=0.997, and p=0.101) is not significant. In the correlation of the MIRs, the results revealed a significant association with the HDI, CHE, and CHE/GDP with the MIR (p<0.001, p<0.001, and p<0.001, respectively).Conclusion: Countries with a higher HDI, more CHE per capita, and higher CHE/GDP tend to have a lower MIR, which indicates a favorable clinical outcome.

Background: The incidence rates of lip and oral cancer have continued to increase, and prognosis is associated with a country’s socioeconomic status. The mortality-to-incidence ratio (MIR) is a reasonable indicator of disparities in cancer screening and treatment. In this study, we aimed to understand the association between economic status and cancer prognosis. Methods: Data were obtained from the Global Cancer Observatory (GLOBOCAN) and the World Health Organization (WHO). The MIRs were compared to evaluate the correlation with the human development index (HDI), the current health expenditure (CHE), and the ratio of CHE over gross domestic product (CHE/GDP) disparities via Spearman’s rank correlation coefficient. Results: The results showed that Asia had the most cases and deaths. In addition, they showed a significant association (p < 0.001, p = 0.005, and p < 0.001, respectively) of the crude rate (CR) of incidence with the HDI, the CHE, and the CHE/GDP. However, their associations with mortality rate (p = 0.303, p = 0.997, and p = 0.101) were not significant. Regarding the correlation of the MIRs, the results revealed a significant association with the HDI, the CHE, and the CHE/GDP (p < 0.001, p < 0.001, and p < 0.001, respectively). Conclusion: Countries with higher HDI, CHE per capita, and CHE/GDP tend to have lower MIRs, which indicates favorable clinical outcomes.

It is common knowledge that apparently similar tumors often show different responses to therapy. This experience has generated the idea that histologically similar tumors could have biologically distinct behaviour. The development of effective therapy therefore, has the explicit challenge of understanding biological behaviour of a tumor. The question is which parameters in a tumor could relate to its biological behaviour ? It is now recognised that the development of malignancy requires an alteration in the program of terminal differentiation in addition to aberrant growth control. In this study therefore, ultrastructural markers that relate to defective terminal differentiation and possibly invasive potential of cells have been identified in human oral leukoplakias, erythroleukoplakias and squamous cell carcinomas of the tongue.
