Challenges in the development and implementation of the National Comprehensive Cancer Control Program in Mexico.

Chronic noncommunicable diseases (NCDs), including cancer, have become the leading cause of human morbidity and mortality. In Mexico, cancer is the third leading cause of death, with a high incidence among the economically active population, a high proportion of advanced stages at diagnosis and limited care coverage for patients. However, no public policy aimed at managing this important public health problem has been developed and implemented to date. This manuscript describes the first interinstitutional proposal of a National Program for Cancer Control, considering the known risk factors, early detection, treatment, palliative care and patient rehabilitation. This manuscript also outlines a series of thoughts on the difficulties and needs that the Mexican health system faces in achieving the main objectives of the program: to decrease the incidence of cancer, to increase survival and to improve the quality of life for this group of patients.

Abstract Chronic noncommunicable diseases (NCDs), including cancer, have become the leading cause of human morbidity and mortality. In Mexico, cancer is the third leading cause of death, with a high incidence among the economically active population, a high proportion of advanced stages at diagnosis and limited care coverage for patients. However, no public policy aimed at managing this important public health problem has been developed and implemented to date. This manuscript describes the first interinstitutional proposal of a National Program for Cancer Control, considering the known risk factors, early detection, treatment, palliative care and patient rehabilitation. This manuscript also outlines a series of thoughts on the difficulties and needs that the Mexican health system faces in achieving the main objectives of the program: to decrease the incidence of cancer, to increase survival and to improve the quality of life for this group of patients.

Resumen Las enfermedades crónicas no transmisibles (ECNT), incluido el cáncer, se han convertido en la principal causa de morbimortalidad de la humanidad. En México, el cáncer es la tercera causa de muerte, con una frecuencia elevada en población económicamente activa, una alta proporción de etapas avanzadas al momento del diagnóstico y una limitada cobertura de atención a quienes la padecen. No obstante, hasta el momento no se ha desarrollado e implementado una política pública dirigida al control de este importante problema de salud pública. Este manuscrito muestra la primera propuesta interinstitucional de un Programa Nacional para el Control del Cáncer, considerando los factores de riesgo conocidos, la detección temprana, el tratamiento y los cuidados paliativos y la rehabilitación del paciente. Asimismo se hacen una serie de reflexiones sobre las dificultades y necesidades a las que el sistema de salud mexicano se enfrenta para alcanzar los objetivos principales del programa: reducir la incidencia, incrementar la supervivencia y mejorar la calidad de vida de este grupo de pacientes.

Sobrevida de mulheres tratadas por câncer de mama no estado do Rio de Janeiro / Sobrevida de mujeres tratadas por câncer de mama en el estado de Rio de Janeiro, Sureste de Brasil / Survival of breast cancer women in the state of Rio de Janeiro, Southeastern Brazil

OBJETIVO: Avaliar a associação entre sobrevida de mulheres com câncer de mama e estrutura e práticas observadas nos estabelecimentos de assistência oncológica. MÉTODOS: Estudo longitudinal retrospectivo, baseado em informações do Sistema de Autorização de Procedimentos de Alta Complexidade do Sistema Único de Saúde e em amostra aleatória de 310 prontuários de mulheres prevalentes atendidas em 15 unidades hospitalares e ambulatoriais oncológicas com quimioterapia entre 1999 e 2002, no estado do Rio de Janeiro. Foram consideradas como variáveis independentes características da estrutura das unidades oncológicas e as suas intervenções praticadas, controlando o efeito com variáveis sociodemográficas e clínicas das pacientes. Para análise dos dados, foram utilizados a técnica de Kaplan-Meier e o modelo de risco de Cox (pseudo-verossimilhança). RESULTADOS: As análises de Kaplan-Meier apontaram associações significativas entre sobrevida e tempo entre diagnóstico e início do tratamento, realização de cirurgia, utilização de hormonioterapia, tipo de hormonioterapia, combinações terapêuticas, tipo de unidade e plano de saúde, volume de atendimento em câncer de mama do estabelecimento e natureza jurídica da unidade. Estimativas obtidas pelo modelo de Cox indicaram associações positivas entre o hazard de morte e tempo entre diagnóstico e início do tratamento, volume de atendimento de câncer de mama do estabelecimento e tipo de unidade combinado ao uso de plano de saúde; e negativas entre sobrevida e cirurgia de mama e tipo de hormonioterapia. CONCLUSÕES: Os resultados mostram associação entre sobrevida de câncer de mama e o cuidado de saúde prestado pelos serviços credenciados, com implicações práticas para pautar novas propostas para o controle do câncer no Brasil.

OBJECTIVE: To assess the association between breast cancer survival and infrastructure and practices of cancer care units. METHODS: Retrospective longitudinal study based on data from the Brazilian information system of authorizations for highly complex cancer procedures covered by the National Health System and a sample of 310 medical records of prevalent breast cancer cases attended at 15 inpatient and outpatient cancer care units providing chemotherapy between 1999 and 2002 in the state of Rio de Janeiro, Southeastern Brazil. Independent variables were infrastructure of cancer units, interventions, and sociodemographic and clinical characteristics of women. Kaplan-Meier method and Cox proportional hazards model (pseudolikelihood) were used for data analysis. RESULTS: Kaplan-Meier analyses pointed out significant associations between survival and time between diagnosis and treatment start, surgery, hormone therapy, type of adjuvant hormone therapy, therapy combinations, type of care unit and health insurance, unit size and category. Estimates obtained from the Cox model showed positive associations between hazard of death and time between diagnosis and treatment, unit size and type combined to use of health insurance, and negative associations between survival and surgery and type of hormone therapy. CONCLUSIONS: The study findings show an association between breast cancer survival and health care provided by affiliated services with practical implications for policy making for cancer control in Brazil.

Estimaciones obtenidas por el modelo Cox indicaron asociaciones positivas entre el hazard de muerte y tiempo entre diagnóstico e inicio del tratamiento, volumen de atención de cáncer de mama del establecimiento y tipo de unidad combinado con el uso del seguro de salud; y negativas entre sobrevida y cirugía de mama y tipo de hormonoterapia.
