HALLAZGOS MAMOGR\uc1FICOS Y ECOGR\uc1FICOS DE PACIENTES CATEGORIZADAS EN BIRADS 4 QUE ACUDEN A LA UNIDAD DIAGN 3STICA DE PATOLOG\ucdA MAMARIA DE LA ASOCIACI 3N LARENSE DE PLANIFICACI 3N FAMILIAR

Se realiz\uf3 un estudio descriptivo retrospectivo con el objetivo de determinar los hallazgos mamogr\ue1ficos y ecogr\ue1ficos de pacientes categorizadas en BIRADS 4 que acudieron a la Unidad Diagn\uf3stica de Patolog\ueda Mamaria de la Asociaci\uf3n Larense de Planificaci\uf3n Familiar, durante el lapso 2013-2014. Para ello, se estudi\uf3 una muestra de 441 pacientes; de los cuales 135 se categorizaron por mamograf\ueda y 306 por ecograf\ueda, cuya edad m\ue1s frecuente fue 38,51% entre 45-54 a\uf1os para el grupo de mamograf\ueda y 35-44 a\uf1os con 34,64% para el grupo de ecograf\ueda. Adem\ue1s, en ambos m\ue9todos se encontr\uf3 BIRADS 4A (67,4% y 83,98%, respectivamente). A su vez, la alteraci\uf3n mamogr\ue1fica m\ue1s frecuente fue densidad nodular y la ecogr\ue1fica n\uf3dulo s\uf3lido. La patolog\ueda benigna predomin\uf3 en ambos m\ue9todos (74,61% y 87,97%), siendo el fibroadenoma m\ue1s com\ufan en BIRADS 4A y 4B mamogr\ue1fico y 4A ecogr\ue1fico, y \ue1rea de fibrosis en BIRADS 4C mamogr\ue1fico y 4B ecogr\ue1fico. La patolog\ueda maligna m\ue1s reportada fue carcinoma ductal invasor en todas las subcategor\uedas. Se concluye que aunque la mamograf\ueda es el m\ue9todo de elecci\uf3n para pesquisa mamaria a nivel mundial, y debe realizarse a partir de los 35 a\uf1os en Venezuela, debe ser siempre complementado con la ecograf\ueda, la cual debe ser tambi\ue9n realizada en pacientes menores de 35 a\uf1os. En caso de diagnosticar lesiones sospechosas de malignidad, efectuar indudablemente el estudio histol\uf3gico de la lesi\uf3n, a fin de diagnosticar de forma precoz el c\ue1ncer de mama y brindar un tratamiento oportuno. PALABRAS CLAVE: C\ue1ncer de mama. Hallazgos ecogr\ue1ficos. Hallazgos mamogr\ue1ficos. ABSTRACT It was decided to conduct a descriptive and retrospective study with the objective to determine the mammographic and ultrasonographic findings of patients categorized in BIRADS 4 who attend to the Diagnostic Breast Pathology Unit of the Larense Family Planning Association, to establish the relationship between these imaging findings and the histopathologic results, during two years (2013-2014). A total of 441 patients was studied; of which 135 are categorized by mammography and 306 by ultrasound. It was found that most patients evaluated by mammography were between the ages of 45 and 54 (38,51%), and those evaluated by ultrasound between 35 and 44 years old (34,64%). Moreover, in both methods was found BI RADS 4A (67.4% and 83.98% respectively). At the same time, the most frequent mammographic alteration was nodular density while the ultrasonographic was solid nodule. The benign pathology predominated in both methods (74,61% y 87,97%), being the fibroadenoma the most common in BIRADS 4A and 4B mammographic and 4A ultrasonographic, and fibrosis area in mammographic BIRADS 4C and 4B ultrasonographic. Invasive ductal carcinoma was the most reported malignant pathology, in all subcategories. It is concluded that although mammography is the method of choice for breast cancer inquest, and should be done after 35 years in Venezuela, should always be supplemented with ultrasound, which must also be performed in patients under 35 years. If suspicious lesions diagnosed undoubtedly make histological study of the lesion, so early diagnosis of breast cancer and provide early treatment. KEY WORDS: Breast cancer. Ultrasound findings. Mammographic findings.
