前哨淋巴结定位和活检术能够对患者腋窝区域淋巴结进行准确分期,已成为评估早期乳腺癌患者腋淋巴结状态的主要方法。传统的核素法与染料法在前哨淋巴结定位中还存在诸如假阴性率高、准确性存在争议等问题。CT淋巴显像由于能够提供乳腺淋巴结及其引流淋巴管之间详细的解剖信息,并准确定位前哨淋巴结,现已逐渐被临床医生所接受。本文对近年来CT淋巴显像技术在乳腺癌前哨淋巴结定位中的研究现状进行综述。
Sentinel lymph node biopsy(SLNB) has become the main evaluation method of the property of axillary lymph nodes,because it can accurately stage axillary lymph node by preoperative localization sentinel lymph node. However,the accuracy of locating the sentinel lymph node by lymphoscintigraphy with radiocolloid and blue dye staining still remain controversial. Computed Tomography lymphography(CT-LG),which can be used to clearly display the relationship of the location between lymph nodes and lymphatic vessels and accurately locate sentinel lymph node,is gradually accepted by clinical physicians. In this review,the research progress of CT-LG in sentinel lymph node localization of breast cancer in recent years was summarized.
