[Radioguided excision of non-palpable XXXX with simultaneous sentinel lymph node biopsy].

@entity5 @entity1 @entity75 @entity1558
As a result of mammographic screening nonpalpable @entity1558 are found with increasing frequency. The surgical management of these lesions presents two main problems: (1) How to localize the lesion pre- and intraoperatively; (2) What should be the extension of the axillary dissection for @entity5 . This study is aimed to evaluate the technical feasibility of radioguided excision of nonpalpable @entity1558 and the possibility of performing simultaneous sentinel lymph node biopsy for @entity5 . Radioguided breast excisions have been performed in our Department since November 2000. The basis of this method is that radioisotope labelled colloid is injected into the lesion under stereo tactic or sonographic guidance. A gamma-probe is used intraoperatively to locate the lesion and guide its excision. Dual agent guided technique is used for sentinel lymph node biopsy. Radioguided breast excision was performed on 85 @entity1 (93 lesion) till February 2002. The localization and excision were successful in 84 @entity1 (92 lesions) (99%). @entity75 were successfully localized and excised in 7 @entity1 . There were 61 parenchyma lesions (66%) and 31 microcalcifications (34%). Localization was performed under sonographic guidance in 44 @entity1 (52%) and under stereotactic guidance in 40 @entity1 (48%). There were 25 benign (27%) and 67 malignant (73%) lesions. Second surgical procedure (mastectomy) was needed in 4 @entity1 (6.5%) because of histologically incomplete excision. Sentinel lymph node biopsy was performed in 50 @entity1 . The biopsy was successful in 45 @entity1 (90%). The sentinel lymph node was histologically positive in 2 @entity1 (4.4%). Radioguided localization with the intraoperative use of a gamma-probe is an easy, rapid and highly accurate technique for removing nonpalpable @entity1558 and allows simultaneous sentinel lymph node biopsy for @entity5 .
