title: The sentinel lymph node: relevance in gynaecological cancers.
abstract: OBJECTIVE
  Sentinel lymph node (SLN) detection is widely practiced in the management of patients with malignant melanoma and beast cancer. Large studies on SLN detection and determination of nodal status have led to changes in the surgical management of the regional lymph nodes in these diseases. More recently attention has focused on other solid cancers, including gynaecological cancers.
  
  
  METHODS
  An extensive literature review of published reports on the SLN in gynaecological cancers was undertaken and the reports were categorised according to the level of evidence provided.
  
  
  RESULTS
  Vulva cancer is the most frequently investigated gynaecological cancer with regard to SLN detection because of its anatomical location and easily accessible nodal basin. Although there are no randomised controlled trials, some data suggest SLN detection in vulval cancer may alter clinical practice and reduce the number of groin lymphadenectomies. The lymphatic drainage of the other gynaecological organs is less predictable, the nodal basin less accessible or less well defined, the techniques not standardised and the evidence for the applicability of SLN detection in the management of these cancers is weak.
  
  
  CONCLUSIONS
  Sentinel lymph node detection in vulval cancer may reduce the need for radical groin lymphadenectomy and thereby reduce morbidity. SLN detection for other gynaecological cancers has little potential to alter clinical practice.
