Abstract
Background: The purpose of this study was to evaluate the usefulness of hook wire localization biopsy under imaging guidance for nonpalpable breast lesions detected radiologically.Methods: This was a descriptive study conducted at the Department of Radiology, Aga Khan University Hospital, Karachi. All patients undergoing needle localization biopsy of a nonpalpable breast lesion under mammographic or ultrasound guidance between January 2009 to December 2010 were included in the study. Patients with incomplete medical records were excluded. All patients' mammograms or ultrasound were categorized using BI-RADS() assessment categories. The percentages of benign and malignant lesions were determined by pathological examination of surgically removed specimens. A correlation was sought between preoperative imaging assessment and the final diagnosis. The complications associated with the procedure were also recorded.Results: A total of 151 biopsies were carried out, of which 80 were performed under mammographic guidance and 71 were performed under ultrasound guidance. The mean age of the patients was 51.89 years. The overall malignancy rate was 25.16%. Of 93 cases reported radiologically as malignant, 60 turned out to be malignant, and of the 58 cases reported as benign on imaging, three proved to be malignant on histopathology. The sensitivity of imaging findings was 95% and the specificity was 62%. The malignancy rate was 5% for benign lesions and 64% for malignant lesions, respectively. There were no complications related to wire localization, and only two patients had minor complications following surgical excision, giving a complication rate of 1.32%.CONCLUSION: Hook wire localization biopsy is a safe and effective procedure for definitive diagnosis of suspicious lesions on imaging, and is more helpful if the imaging findings are suspicious.
