Results
The study population included 141 (55 %) IR, and 115 (45 %) HIR EC
patients. LND was not performed in 33 (23.4%), and 31 (27%) patients
in IR, and HIR EC patients, respectively. The lymph node involvement was
10.3% (n=20) among all patients. During the median follow-up of 41
months (range, 12–222), 12 (6.2 %) patients with LND, and 5 (7.8 %)
patients without LND had disease recurrence (p=0.77). LND did not
improve OS and DFS in IR and HIR EC patients (p=0.92, p=0.80). And the
lymph node count was not associated with OS and DFS for all subsets of
patients with EC grouped by recurrence risks.
