Current management of the axilla in patients with clinically node-negative breast cancer: a nationwide survey of United Kingdom breast surgeons
Tóm tắt
Precise knowledge of axillary lymph node status is essential in the treatment of operable carcinoma of the breast. For many years, axillary nodal clearance (ANC) has been an integral part of the conventional management of early-stage breast cancer. During the last few decades the trend of these surgical procedures has been one of decreasing invasiveness in order to try and achieve a much lower level of morbidity. To help reach this improved level of treatment the concept of the sentinel lymph node (SLN) was utilized. Recent studies have shown that SNB can provide an accurate assessment of the axillary nodal status in clinically node negative patients, negating the need to remove the majority of the axillary contents and thus reducing morbidity. A recent meta-analysis of all the literature to date appears to reveal that the dual technique (blue dye and technetium-labelled sulfur) is the gold-standard for successful identification of the SLN in the context of early-stage breast cancer. We aim to highlight the on-going wide range of differing methods employed, and compare this to the gold-standard recommended guidelines. A questionnaire was devised to provide a snapshot overview of the current management of the axilla in patients with clinically node-negative T1 invasive breast cancer amongst UK beast surgeons in August 2006. Of the 271 UK surgeons, 74 (27.3%) performed ANC as the initial management of the axilla in patients with clinically node negative T1 invasive breast cancer, 56 (20.7%) used axillary node sampling (not directed by sentinel node mapping) and a total of 141 (52.0%) used the technique of SNB, of which 50 (18.5%) used blue dye alone and 91 (33.6%) used a combination of blue dye and radioisotope. Despite the obvious advantages, our survey has revealed that the procedure is only used by 52% of British breast surgeons in this subgroup of patients (clinically node negative, tumour equal of smaller than 2 cm) most of whom have no disease within the axilla. The reasons for this include limited hospital resources and lack of surgeons training and accreditation and ARSAC license (nuclear medicine license).
