前哨淋巴结(SLN)是最先接受原发肿瘤淋巴回流的区域且最能反映肿瘤的转移情况,SLN是否存在微转移决定着前列腺癌盆腔淋巴结清扫术式的选择,同时也与患者后期治疗及预后密切相关,故精确定位SLN尤为关键。本文通过对术前SLN成像、术中SLN显影及定位新方法的探讨,综述了前列腺癌SLN示踪技术的应用研究进展。
Sentinel lymph node (SLN) is the first area to receive lymphatic flow of the primary tumor and best reflects the metastasis of the tumor. Whether SLN micrometastasis determines the choice of pelvic lymph node dissection for prostate cancer is also closely related to the post-treatment and prognosis Closely related, so pinpoint SLN is particularly crucial. This article summarizes the research progress of SLN tracing of prostate cancer through the discussion of preoperative SLN imaging, intraoperative SLN imaging and positioning of new methods.
