Analysis of cancer mortality in Mexico using the results of the Global Burden of Disease 2021 study.

BACKGROUND: In Mexico, cancer mortality rates have undergone changes over the past decades. OBJECTIVE: To analyze the evolution of cancer mortality rates in Mexico between 1990 and 2021. MATERIALS AND METHODS: Based on the Global Burden of Disease study, the mortality rates for the 10 most prevalent types of cancer in Mexico were obtained, at the national and regional level and by states, considering different age groups and gender. Global Burden of Disease reassigns misclassified causes and distributes them among different types of cancer; subsequently, it models and adjusts the causes to the total number of deaths with a model of a set of causes of death and a cause corrector, which corrects INEGI's mortality records. RESULTS: The cancer mortality rate went from 117.87 in 1990 to 84.18 in 2021. In women, breast, cervical, stomach and lung cancers were the most frequent. In men, the most common were prostate, stomach, lung, and colon and rectum cancer. The decrease in cancer mortality for men and women stood out, particularly from lung and cervical cancer. CONCLUSIONS: The results provide information for the development of health policies and specific prevention and control strategies to address the impact of cancer in Mexico.

ANTECEDENTES: En México, las tasas de mortalidad por cáncer han experimentado cambios a lo largo de las últimas décadas. OBJETIVO: Analizar la evolución de las tasas de mortalidad por cáncer en México entre 1990 y 2021. MATERIALES Y MÉTODOS: Del Global Burden of Disease (GBD) se obtuvieron las tasas de mortalidad de los 10 tipos de cáncer más predominantes en México, en el ámbito nacional y por estados, considerando distintos grupos etarios y el sexo. En el GBD se reasignan las causas mal clasificadas y se distribuyen entre los distintos cánceres; posteriormente se modelan y ajustan las causas al total de fallecimientos con un modelo de conjunto de causas de muerte y un corrector de causas, con lo cual se corrigen registros de mortalidad del INEGI. RESULTADOS: La tasa de mortalidad por cáncer pasó de 117.87 en 1990 a 84.18 en 2021. En las mujeres, los cánceres de mama, cervicouterino, estómago y pulmón fueron los más frecuentes; en los hombres, de próstata, estómago, pulmón, colon y recto. Destacó la disminución de la mortalidad por cáncer en hombres y mujeres, en particular por cáncer de pulmón y cérvix uterino. CONCLUSIONES: Los resultados ofrecen información para desarrollar políticas de salud y estrategias de prevención y control específicas para enfrentar el impacto del cáncer en México.

Cancer Trends in Mexico: Essential Data for the Creation and Follow-Up of Public Policies.

Purpose Cancer in a country like Mexico is a challenge for the current health system and for public health. However, the statistics about cancer in Mexico are scarce, so epidemiologic surveillance needs to be improved. The objectives of this article were to describe the extent of cancer and to estimate the national burden of cancer through 2020. Materials and Methods To meet this objective, an analysis of secondary official sources was performed. The cancer cases through 2020 were estimated on the basis of trends in mortality and the projection of incident cases reported by GLOBOCAN. Results In 2013, cancer was the cause of 12.84% of all deaths in Mexico. It is projected that the prevalence of cancer will be 904,581 by 2017 and will reach 1,262,861 by early in the next decade (ie, 2020). Conclusion Available data for cancer are incomplete. The development and implementation of population-based cancer registries in Mexico are essential. Assessment of the future outlook of cancer in Mexico will provide awareness of future challenges and can help health systems prepare to face them.
