[The attitude before subclinical breast lesions on mammography].
Mammographic screening and improvement of mammography resolution have resulted in the increasingly frequent identification of small-size mammary lesions that have no clinical expression. If in Western countries, approximately one quarter of breast cancers are discovered when clinically occult, in Romania such cases are rare and, most of the times, discovered merely by chance. Infraclinical mammary lesions identified by mammography pose problems concerning the appropriate response. The paper assesses the various diagnosis and therapy choices as well as the localization techniques to be employed in order to establish the best approach. We describe twelve cases of infraclinical mammary lesions identified by mammography. In two of this cases fine needle aspiration biopsy with cytological examination was used, and in one case we performed core biopsy and histological examination. In those cases, lesion localization has been performed using stereotactic X-ray devices. In nine cases, we performed excisional biopsy with histologic assessment. In four of those cases, the lesions proved to be malignant. Preoperative localization was performed with hookwires placed in the proximity of the lesion under mammographic control. In five of those cases, lesion coordinates have been determined by stereotaxy. Using this technique, we removed, in all cases, the clinical lesions identified by mammography. We believe surgical excision to be the best approach in such lesions. Total removal of the lesion enables a thorough histopathological examination resulting in more accurate diagnosis. Curative surgery is also possible within the same surgical procedure. Unless preoperative localization is performed the surgeon is in the position to excise an image that has no clinical expression. Under this circumstances surgical removal is performed blind, as the lesion is hard to be found even intraoperatory. Preoperative localization provides guidance to the surgeon, ensures removal of the lesion that has been identified by mammography and helps avoids unnecessary mammary resection.
