Trends in oesophageal cancer mortality in Montenegro, 1990–2018

Abstract

Abstract Background Oesophageal cancer (OC) is a significant public health issue, despite the decreasing trends in OC mortality rates observed globally in the past decades. The objective of our study is to analyze the pattern of OC mortality in Montenegro between 1990 and 2018 and contribute to the development of a national long-term strategy for the prevention and control of this malignancy. Methods The data on OC death cases in Montenegro between 1990 and 2018 were collected. The mortality rates were standardized according to the World Standard Population. The Joinpoint, Linear and Poisson regressions were applied to analyze the OC mortality trend. Results Joinpoint regression analysis showed an increase in death rates for men and the overall level which were not statistically significant. However, the number of cases increases significantly with an average annual percentage change (AAPC) increase of 2.6% for the overall level [AAPC (95% CI)=2.6 (1.0–4.2); P = 0.002] at the expense of the increase in men, which on average was 2.6% annually [AAPC (95%CI) = 2.6 (1.2–4.1); P = 0.001]. The age groups 55–64 and 65–74 have the highest percentage of deaths cases from OC with 30.6% and 31.4%, respectively. Conclusion Montenegro has witnessed a recent increase in the number of deaths from OC, although the mortality rates remain stable. National strategies to further reduce mortality rates for OC are necessary. Individuals aged 55–64 and 65–74 need specific attention during the ongoing monitoring of this cancer.
