  1. DR: preoperative detection rate (drainage on lymphoscintigraphy); SLNs: sentinel lymph node. SPECT/CT: single photon emission computed tomography
  2. *During surgery, three of the 52 patients showed peritoneal carcinomatosis, so SLN biopsy was ruled out. That results in 49 patients in whom SLN biopsy was attempted
