Application of sentinel lymph node tracer techniques in prostate caner / 中华男科学杂志

ABSTRACT

The sentinel lymph node (SLN) is the first node receiving lymphatic drainage of a tumor and best reflects tumor metastasis. Whether there is a micrometastasis in SLN determines the choice of pelvic lymph node dissection for prostate cancer and is closely related to later treatment and prognosis. Therefore, precise localization of SLN is essential. This review discusses the application of SLN tracer techniques, such as preoperative imaging and intraoperative lymphoscintigraphy and localization of SLN, in prostate cancer.
