3. Locations of SLNs in the pelvis
The locations of all SLNs identified were in both sides of the pelvis
(Figure1.C). The majority of SLNs (85.71%) were found in the pelvis
along the iliac vessels and in the obturator space: external iliac, 486
(33.38%); obturator, 438 (30.08%); the common iliac, 217 (14.90%);
and the internal iliac, 107 (7.35%). Furthermore, we found SLNs in some
unusual anatomic sites, including the presacral (4.33%) and parametrial
(3.02%) regions (Table S2).
