Image-guided biopsy of non-palpable breast lesions: Experience of a university hospital in Mexico City.

Abstract

e11098 Background: Breast cancer is the most common cancer in women in Mexico. It is mostly diagnosed at advanced stages. Objective: To describe the experience of image-guided biopsies of non-palpable breast tumors in a University Hospital in Mexico City. Methods: Medical records from the Radiology and Oncology Department (January 2007 - April 2011) were reviewed. Patients with incomplete medical records as well as those lacking imaging control and pathology report were excluded. Results: A total of 123 medical records were obtained,12 were excluded. The median age was 50 years (rank 21-88). Most patients were asymptomatic. Medical indications leading to biopsy: see table below. Of the studied population, 56% had a family history of any type of cancer; 40% had a family history of breast cancer. Nine patients had a past medical history positive for breast cancer, 8 patients had a past medical history of any type of cancer. 26 patients were nulligravid and 60 post-menopausal; of which 27 had received hormone replacement therapy. 24 patients had positive contraceptive use. Most patients were catalogued as BIRADs 4A. From all the imaged-marked lesions, only 18 were malignant; 72% of which were carcinoma in situ. Most procedures were ambulatory; only 15 patients had to be admitted. The complications rate was very low (6%), 1 procedure-related infection, 3 seromas and 3 hematomas. Conclusions: Imaging-guided biopsies are a safe, with very low morbidity, accessible procedure. It helps to prompt effective treatment; especially in patients with non-palpable lesions who would otherwise not be diagnosed until advanced stages. [Table: see text]
