Sentinel lymph node concept in gastric cancer with solitary lymph node metastasis

Table 1 Distribution of solitary lymph node metastasis

Location of positive node	Location of primary tumor
	Upper	Middle	Lower
Right cardial (No1)	2(N1)	1(N1)	1(N2)
Lesser curvature (No3)	7(N1)	7(N1)	20(N1)
Greater curvature (No4d)		2(N1)	14(N1)
Greater curvature (No4s)	2(N1)		1(N3)
Surprapyloric (No5)		2(N1)	5(N1)
Infrapyloric (No6)	2(N1)	3(N1)	6(N1)
Left gastric artery (No7)	2(N2)	2(N2)	3(N2)
Common hepatic artery (No8a)	1(N2)	1(N2)
Splenic artery (No11p)			1(N2)
Proper hepatic artery (No12)		1(N3)

No4d and 4 s represent nodes on right and left half of greater curvature respectively; No8a represents nodes on the ante-rior or upper of CHA; No11p represents nodes on proximal splenic artery.
