Manejo quirúrgico de cáncer subclínico detectado en mamografía Como densidad nodular, no visible al ultrasonido

objective: the purpose of these work is evaluate the surgical management of non-palpable breast cancer diagnosed as a mammographic visible mass on screening, non visible ultrasonographic. methods: analyzed retrospectively of tree cases with the diagnosis of non palpable breast lesion visible at the screening mammography and non visible at the ultrasound, they were excised after preoperative tumor localization with a wire. the performance of the sentinel lymph node biopsy was evaluated, if it was in the second surgery after the definitive histopathology confirmation. results: all the three cases underwent wire localization prior to the tumorectomy, in 2 cases the tumorectomy had wide margins, and in the other one they were close. in one patient we did tumorectomy and sentinel lymph node biopsy in the same surgical procedure. two cases had invasive lobulillar carcinoma, one of them multifocal and in the other case invasive ductal. the average ages were 63 years (62 to 64 years). the averages of the lesion were 0.9 cm (range in four lesions 0.7 to 1.2 cm). in all the patient were performed the sentinel lymph node biopsy, being positive in just one of the cases. conclusions: in patients the wire radio-localization represents a simple and efficient method to obtain the biopsy and could be performed in any center that counts with a mammographic. we suggest performing the sentinel lymph node biopsy with patent blue during the initial surgery if there is a strong confirmation of malignant.
