前哨淋巴结绘图技术在外阴癌、宫颈癌及子宫内膜癌中已有较多研究，其意义在于对临床早期患者可进行准确的分期，筛选出无淋巴结转移的患者，从而避免不必要的广泛性手术切除，在保证疗效的同时减少手术切除的范围并降低相应并发症的发生率，提高患者的生活质量。本文就近年来国外在该领域的研究作一综述。“,”Numerous studies have been involved in sentinel lymph node mapping in gynecological tumors, such as vulvar cancer, cervical cancer and endometrial cancer. The sentinel lymph node technique can accurate clinical staging of patients in early stage,screen out patients without lymph node metastasis, thus avoid unnecessary extensive surgery, ensuring efficacy while reducing the incidence of complications, and improving the patients?life quality. In this review, we will focus on recent developments abroad of sen?tinel lymph node mapping in gynecological malignant tumors.
