UNASSIGNED: e15560 Background: To compare the size of lymph nodes (LNs) of para-aortic or pelvic area between metastatic and non-metastatic LNs retrospectively in pathologically confirmed lymph node positive gynecologic @entity5 . METHODS: The lengths of @entity3173 and thickness of all dissected LNs were measured by gage on specimen slides in pathologically confirmed LN positive (LN+) 18 gynecologic malignant @entity1 . Student t test was used for statistically analysis. RESULTS: The size of 821 LNs, 196 para-arotic LNs (PAN) and 625 pelvic LNs ( @entity6841 ) were measured from 8 of @entity5 , 5 of @entity43 . The median number of dissected LNs was 44 (ranged 16 to 97) per case. Twenty-seven PAN (PAN+) and 62 @entity6841 ( @entity6841 +) were ascertained with metastasis of primary @entity5 . Median @entity3173 and thickness of LN+ were 9.7mm (95% confidential interval (CI); 9.0, 10.5) and 5.4mm (95%CI; 5.0, 5.8) and median those of non-metastasized LN (LN-) were 4.2mm (95%CI; 3.9, 4.4) and 2.2mm (95%CI; 2.1, 2.4). There were statistically differences between the two groups (p<0.0001). In subgroup analysis, median @entity3173 (8.5mm [95%CI; 7.2, 9.7]) and thickness (4.8mm [95%CI; 4.2, 5.5]) of PAN+ were statistically larger (p<0.0001) than those (3.9mm [95%CI; 3.4, 4 .4] and 2.3 mm [95%CI; 2.0, 2.6]) of PAN-. And also, median @entity3173 (10.3mm [95%CI; 9.3, 11.2]) and thickness (5.7mm [95%CI; 5.2, 6.2]) of @entity6841 + were statistically larger (p<0.0001) than those (4.2mm [95%CI; 3.9 4.5] and 2.2 mm [95%CI; 2.1, 2.4]) of @entity6841 -. CONCLUSIONS: The size of metastatic LNs increases in both @entity3173 and thickness. If we could detect 7.2 mm in @entity3173 or 4.2 mm in thickness of PAN or 9.3 mm in @entity3173 or 5.2 mm in thickness of @entity6841 , it would be possible to skip lymphadenectomy of para-aortic or pelvic area with 95%CI by pre- or intra-surgical evaluation.
