The prognostic role of lymph node dissection in early-stage endometrial cancer
The prognostic role of LND is universally accepted in early-stage EC. LN metastasis is the most common site of extrauterine spread(7) and an important prognostic factor associated with EC(13). LND increases the prognostic value of the FIGO 2009 staging system(23) and is more accurate than preoperative imaging or palpation of LNs(13,14). It provides precise prognostic information, guiding the need for adjuvant radiotherapy, chemotherapy or both(13,24) In women with negative LNs, unnecessary adjuvant treatment can be prevented(7).
