AIM:To investigate the distribution pathway of metastatic lymph nodes in gastric carcinoma as a foundation for rational lymphadenectomy. METHODS:We investigated 173 cases with solitary or single station metastatic lymph nodes(LN)from among 2476 gastric carcinoma patients.The location of metastatic LN,histological type and growth patterns were analyzed retrospectively. RESULTS:Of 88 solitary node metastases cases,65 were limited to perigastric nodes(N_1),while 23 showed skipping metastasis.Among 8 tumors in the upper third stomach,3 involved right paracardial LN(station number:No.1),and one in the greater curvature was found in No.1.In the 28 middle third stomach tumors,10 were found in LN of the lesser curvature(No.3)and 6 in LN of the left gastric artery(No.7);5 of the 20 cases on the lesser curvature spread to No.7,while 2 of the 8 on the greater curvature metastasized to LN of the spleen hilum(No.10).Of 52 lower third stomach tumors,13 involved in No.3 and 19 were detected in inferior pyloric LN(No.6);9 of the 29 cases along the lesser curvature were involved in No.6. CONCLUSION:Transversal and skipping metastases of sentinel lymph nodes(SLN)are notable,and rational lymphadenectomy should,therefore,be performed.
