title: [The preoperative marking of nonpalpable breast lesions: the technic and results].
abstract: 189 non-palpable breast lesions in 182 patients were localized using conventional mammographic apparatus, a wire grid compression plate and a cannula with a hooked mandrin. The technique of the examination for defining the lesion in three planes and fixation of the lesion with the wire is described. In 173 instances (91.5%), the lesion was found at the first biopsy and subsequent biopsies were necessary on only 24 occasions. One lesion (0.5%) was missed completely. 47 carcinomas were found (24.9%) and the incidence of malignancy increased from 14.3% to 33.3% during the series. The mean ratio defining the size of the biopsy and the size of the lesion was 3.3 and indicates good preservation of breast tissue. Radiographs of the specimen taken with compression showed 186 lesions (98.4%). The method, which is comfortable for the patient, provides satisfactory detection and localization of the lesions; results are similar to those of stereotactic methods but this method is quicker and much less expensive.
