Guided aspiration cytology by ultrasound in diagnosing mammary pathologies

Abstract

A retrospective transversal study was carried out on the basis of an investigative-action project, with the objective of identifying the effectiveness of fine needle, ultrasound-guided aspiration cytologies made in the Hospital Jose Ramon Lopez Tabrane, and that way to diagnose as early as possible mammary pathologies, giving special importance to pre-malign and malign ones, because early diagnose allows decreasing morbimortality for this condition, in a period from March to September 2009. The universe were 141 patients, who assisted the consultation of fine needle ultrasound-guided cytology, presenting palpable lesions and non palpable ones visualized by ultrasound and mammography. Cytologies were made directly from the observed lesion and were grouped according to age, ultrasound, mammographic findings and post-surgery biopsies. Data were collected from the consultation records and cytologies and biopsies records of the Pathologic Anatomy Department of our hospital. We analyzed ultrasound and mammographic diagnosis and compared them with the histological ones. In patients surgically operated, imaging and cytological diagnosis was correlated with final biopsy. The bigger percent of studied patients belonged to the age group from 31 to 49 years old. There were a greater number of benign pathologies, with a bigger percent of echogenic images to ultrasound, corresponding by mammography to aisled nodules. It was proved a predominance of fibroadipose tissue (16,73 %) by histology. There were diagnosed 9 cellular atypicities (6,59 %) and 8 infiltrating ductal carcinomas (5,77 %). 17 patients were operated with cytological diagnosis of atypia as infiltrating ductal carcinoma (12,36 %), totally coinciding this diagnosis with the post-surgery biopsy made in each case
