Resumen
El cáncer de mama es la neoplasia ginecológica más frecuente en todo el mundo, pues se estiman 1,152.161 casos nuevos por año. En Estados Unidos constituye 32% de todos los tipos de cáncer en mujeres y 15% de mortalidad, con mayor incidencia después de los 50 años de edad.1 La OMS promueve el control del cáncer de mama en el marco de los programas nacionales de lucha contra el cáncer, integrándolo en la prevención y el control de las enfermedades no transmisibles.2 En Ecuador representa la segunda neoplasia más frecuente (10.3%), después del cáncer cervico-uterino, principalmente en pacientes de entre 40 y 54 años de edad y la principal causa de muerte por cáncer en la población femenina. El objetivo del presente estudio fue establecer cuáles son las características radiológicas del carcinoma in situ de la mama en pacientes diagnosticadas por ecografía en quienes se realizó biopsia con aguja guiada con ultrasonido y posteriormente biopsia quirúrgica en el Servicio de Imagenología del Hospital Regional 2 del IESS. La investigación se realizó durante el período comprendido entre julio de 2012 y junio de 2013. El estudio realizado es de tipo observacional, correlacional, descriptivo, prospectivo, de corte longitudinal en 160 pacientes de mayores de 18 años de edad, de sexo femenino, a las que al acudir al Servicio de Imagenología y Ultrasonido se les realizó BAAF por nódulo mamario. Se excluyeron del estudio pacientes que no tuvieron estudio de diagnóstico por imágenes (ultrasonido) y sin diagnostico anatomopatológico. Los resultados durante el examen ecográfico se evaluaran las características radiológicas (ecogenicidad) y morfológicas del nódulo mamario, lo cual permitirá categorizarlos según sus formas, bordes, márgenes. De los 160 casos de tumores mamarios, el 62,5% fue tumor benigno y el 37,5% fue tumor maligno según el estudio histopatológico. El tipo histológico benigno más frecuente fue el fibroadenoma (59%) y el maligno fue el carcinoma ductal infiltrante (73%). Las lesiones malignas, según ecografía presentan con mayor frecuencia lesión sólida hipoecogénico, bordes irregulares, márgenes espiculados y se localizan en el CSE de la mama derecha.
Breast cancer is the most common gynecologic malignancy in the world, as 1152.161 new cases per year are estimated. In the U.S. constitutes 32% of all cancers in women and 15% mortality, with the highest incidence after 50 years of age.1 WHO promotes the control of breast cancer within the framework of national control programs cancer, integrating prevention and control of noncommunicable diseases transmisibles.2 in Ecuador is the second most common malignancy (10.3%) after cervical-uterine cancer, mainly in patients between 40 and 54 years of age and the leading cause of cancer death among women. The aim of this study was to establish what are the radiological features in situ of the breast diagnosed by ultrasound in patients in whom biopsy was performed with ultrasound-guided needle biopsy and subsequent surgical Imaging Service Regional Hospital IESS 2 carcinoma. The research was conducted during the period between July 2012 and June 2013. The study is observational, correlational, descriptive, prospective, longitudinal cutting in 160 patients over 18 years of age, female sex, you to go to the Office Imaging and Ultrasound underwent FNAB for breast lump. Were excluded patients who had imaging study (ultrasound) without pathological diagnosis. Findings at ultrasound examination radiological characteristics (echogenicity) and morphological assess breast nodule, which will categorize them according to their shapes, borders, margins. Of the 160 cases of mammary tumors, 62.5% were benign tumor and malignant tumor was 37.5% according to histopathology. The most common histological type was benign fibroadenoma (59%) and malignant invasive ductal carcinoma was (73%). Malignant lesions by ultrasound occur more frequently hypoechoic solid lesion, irregular edges, spiculated margins and are located in the CSE of the right breast
