Contribution of hook-guided breast biopsy to the pathological diagnosis of mammographic lesions.
This study was carried out to evaluate the reliability of a diagnostic approach with close cooperation between radiologists and surgeons for minimal breast disease. From 1993 to 1995, 152 evaluable patients with non palpable breast lesions were examined by mammography and their lesion was localized with a hook wire before being referred to the surgeon for biopsy. Comparison of mammography findings with pathological diagnosis indicated a good predictive value for benign lesions with only 8% non concordant diagnosis and a rather low predictive value in case of suspect mammograms with only 64% positive diagnosis. With hook-guided breast biopsy, a correct diagnosis was established in 93% of the cases. The remaining breast samples were either non contributory or necessitated a second biopsy. Several recommendations are proposed for improving accuracy of breast sampling such as securing the hook into the gland, orienting the limits of resection, sending specimen for X-ray study and inking the margins for the pathologist. This field experience revealed that some progress are to be made in diagnosis in particular by standardization of mammography and pathological criteria, more precise localization of the lesions with the hook and more refined surgical techniques for breast biopsy.
