Cancer incidence and mortality in Quito: information to monitor cancer control policies
Abstract
Introduction: cancer represents a challenge for global public health, since it requires a comprehensive, transdisciplinary, and sustainable strategy for its control. In this context, epidemiological surveillance systems, such as Population-Based Cancer Registries (PBCR), become key actors for the development and monitoring of the implemented actions.
Objective: within the framework of the national cancer plan proposed in 2017 for the country, this study analyze the trend in cancer incidence and mortality rates during the period 1985-2017.
Methods: age-standardized incidence and mortality rates were estimated using data from PBCR of Quito. For the analysis of the trends, of selected locations, joinpoint regression and Average Annual Percent Change (AAPC) was used.
Results: A sustained increase in cancer incidence (AAPC Men= 1.5%, 95% Confidence Interval [CI]: 1.2 - 1.7; AAPC Women: 0.7%, 95% CI: 0.4 - 1.0) and mortality rates (AAPC Men= 2.0%, 95% CI: 1.8 - 2.3; AAPC Women= 1.3%, 95% CI: 1.1 - 1.6) was observed in Quito throughout the study period. There was a sustained increase in incidence and mortality rates of breast, prostate, colon-rectum, thyroid and lymphoma cancers. While the incidence rates of cancer of the cervix and stomach, related to infectious agents, decreased.
Conclusion: The information presented by the PBCR of Quito serves as a reference for the prognosis of cancer in the country and as a baseline for its control. Actions to strengthen prevention and promotion strategies against cancer are urgent, especially in breast and cervix cancer, to mitigate its impact on Ecuadorian society.
