Incidencia del cáncer de mama en la provincia de Granma. Período 1997-2006. I parte.

Breast cancer has a high incidence in women from Granma province. It was performed the present research with the objective to identify the characteristics of its incidence. It was designed an observational descriptive study, for that purpose there were selected the patients with breast cancer included in the National Cancer Record (1997- 2006). The information was gathered in absolute numbers, percentages and rates. For the analysis of the temporary tendency of the incidence rate it was used the segment regression method and for the geographic distribution it was used the descriptive method of cartographic representation of the risk measure. The greatest risk to get ill was observed in the sixth decade of life, a 30 % of women were under 50 years, with a growing tendency. There were found geographic differences in the incidence, an important percent of patients were belately diagnosed, without a clinical stage, without the histological or cytological verification and only with a death certificate. It was concluded that the age, risk factors, and life styles play an important role in the incidence of this disease and the quality of medical care.El cáncer de mama tiene una alta incidencia en las mujeres de la provincia de Granma.

Se diseñó un estudio observacional descriptivo, se seleccionaron para tal fin las pacientes con diagnóstico de cáncer de mama incluidas en el Registro Nacional de Cáncer (1997-2006). La información fue resumida en números absolutos, razones, porcentajes y tasas. Para el análisis de la tendencia temporal de las tasa de incidencia se utilizó el método de regresión segmentada y para la distribución geográfica el método descriptivo de la representación cartográfica de la medida del riesgo. El mayor riesgo de enfermar por cáncer de mama se observó en la sexta década de la vida, un 30 % de las mujeres eran menores de 50 años, con una tendencia creciente. Se encontraron diferencias geográficas en la incidencia, un porciento importante de las pacientes se diagnosticaron tardíamente, sin etapa clínica, sin verificación histológica o citológica y solo por certificado de defunción. Se concluye que la edad, factores de riesgo y los estilos de vida juegan un papel importante en la incidencia de esta enfermedad y la calidad de la atención médica

The importance of registries in cancer control

Cancer is one of the major causes of morbidity and mortality in the world, with 14.1 million new cases and 8.2 million deaths annually. A marked disparity exists between developed countries and developing countries, with 57% of new cases and 65% of deaths in 2012 occurring in developing countries. This global picture can only be obtained because of data obtained from population-based cancer registries, which allow cancer estimations for different geographic areas. Our objective is to perform a review of different types of registries and their role in the control of cancer. These types of registries are lacking in developing countries. In Central and South America, only 6% of the population is included in cancer registries versus 83% in North America. It is necessary to increase the coverage of cancer registries to obtain more reliable data that will more appropriately guide control programs. DOI: http://dx.doi.org/10.21149/spm.v58i2.780

The importance of registries in cancer control

Abstract Cancer is one of the major causes of morbidity and mortality in the world, with 14.1 million new cases and 8.2 million deaths annually. A marked disparity exists between developed countries and developing countries, with 57% of new cases and 65% of deaths in 2012 occurring in developing countries. This global picture can only be obtained because of data obtained from population-based cancer registries, which allow cancer estimations for different geographic areas. Our objective is to perform a review of different types of registries and their role in the control of cancer. These types of registries are lacking in developing countries. In Central and South America, only 6% of the population is included in cancer registries versus 83% in North America. It is necessary to increase the coverage of cancer registries to obtain more reliable data that will more appropriately guide control programs. Resumen El cáncer es una de las principales causas de morbi-mortalidad en el mundo con 14.1 millones de casos nuevos y 8.2 millones de muertes. Existe marcada disparidad entre países desarrollados y en vías de desarrollo: 57% de los casos nuevos y 65% de las muertes registradas en 2012 ocurrieron en países en vías de desarrollo. Sólo es posible describir este panorama mundial a partir de los datos obtenidos de los registros poblacionales de cáncer, que permiten realizar estas estimaciones en las diferentes áreas geográficas. El objetivo de este trabajo es realizar una revisión sobre los diferentes tipos de registros y su papel en el control del cáncer. En los países en vías de desarrollo existe una notable carencia de este tipo de registros. En Centro y Sur América sólo 6% de la población cuenta con registros de cáncer frente a 83% en América del Norte. Es necesario ampliar la cobertura de los registros de cáncer para la obtención de datos más confiables que guíen más oportunamente los programas de control
