Reflections and proposals for the standardization of lymphadenectomy for gastric carcinoma.
In this paper, I consider: the value of various histological procedures; the feasibility and reproducibility of lymphadenectomies according to the Japanese Research Society for Gastric Cancer; the minimal number of lymph nodes (LNs) which should be resected for each type of lymphadenectomy; and the best way to present the results concerning the LN status. A reproducible lymphadenectomy is proposed for simplified anatomical level I (anterior plane, along the gastric curves) and level II (intermediate plane, along the gastric arteries), without spleno-pancreatectomy for the majority of cases. The LN status must be based on the total number of involved nodes, as recommended by the 1997 UICC classification. These simple, reproducible guidelines offer a basis for the standardization of procedures used for the treatment and classification of gastric carcinomas.
