- W1987609596 abstract "La detección temprana del cáncer de mama se ha beneficiado del creciente uso de la mamografía de cribado y de las biopsias de mama para las lesiones no palpables Hemos revisado la efectividad de la biopsia guiada por arpón para lesiones mamográficas de 84 pacientes que acudieron o fueron remitidas a nuestro hospital durante un período de 4 años Se detectó malignidad en 24 de las 84 biopsias (28%). La rentabilidad de la biopsia fue mayor para los hallazgos mamográficos de masas espiculadas o estrelladas (50%; p < 0,01). La mayoría de las biopsias (77%) fueron llevadas a cabo debido al hallazgo de microcalcificaciones, masas circunscritas aumentadas de tamaño o nódulos bien definidos con una tasa de biopsias positivas del 23%. Las tasas fueron mayores en pacientes con antecedentes personales (29%) o familiares (55%) de cáncer de mama y en pacientes posmenopáusicas (25%) Estos resultados demuestran que factores como la edad, la historia personal o familiar de cáncer de mama y ciertas características mamográficas de lesiones mamarias están asociados con altas tasas de positividad de las biopsias, siendo la tasa de rentabilidad de la biopsia comparable a la de otros hospitales The growing use of mammographic screening and breast biopsies has improved the early detection of nonpalpable breast lesions We assessed the effectiveness of needle-guided biopsy in nonpalpable radiographic abnormalities in 84 patients who attended or were referred to our hospital over a 4-year period Malignancy was detected in 24 of 84 biopsies (28%). Biopsy yield was highest for mammographic findings of spiculated or stellate masses (50%, p < 0.01). Most biopsies (77%) were performed because of mammographic findings of microcalcifications, enlargement circumscribed masses, or well-defined nodular densities with a positive biopsy rate of 23%. Rates were higher in patients with a personal (29%) or family history (55%) of breast cancer and in postmenopausal women (25%) These results demonstrate that factors such as age, a personal or family history of breast cancer, and certain mammographic features of breast lesions are associated with positive biopsy rates. The biopsy yield in this study was similar to that of other hospitals" @default.
