Pathologic results of LNs

Pathologic result	HG (n = 97)	LGAL (n = 97)	P-value
N stage			0.495
0	56 (57.7)	56 (57.7)
1a	18 (18.6)	17 (17.5)
1b	14 (14.4)	12 (12.4)
1c	0 (0)	1 (1.0)
2a	4 (4.1)	9 (9.3)
2b	5 (5.2)	2 (2.1)
Total harvested LNs	20.9 ± 13.2	20.2 ± 9.2	0.673
Total metastatic LNs	1.75 (0–30)	1.15 (0–12)	0.247
Total harvested LNs of IMA	-	2.19 (0–11)	-
Total metastatic LNs of IMA	-	0.01 (0–1)	-

Values are presented as number (%), mean ± standard deviation, or mean (range).

HG, high group; LGAL, low group with additional LN retrieval; LN, lymph node; IMA, inferior mesenteric artery.

N stage was analyzed by chi-square test. Total harvested LNs and total metastatic LNs were analyzed using the Student’s t-test.
