Gastrectomy with extended lymphadenectomy beyond D2 is classified as a non-standard gastrectomy, and could be considered for the following cases, although hard evidence is lacking, on the condition that it can be conducted safely.
Dissection of No. 10 (splenic hilar lymph nodes) with or without splenectomy for cancer of the proximal stomach invading the greater curvature (D2+No. 10) (CQ3-2).
Dissection of No. 14v (superior mesenteric venous lymph node) for cancer of the distal stomach with metastasis to the No. 6 lymph nodes (D2+No. 14v).
Dissection of No. 12b (in the hepatoduodenal ligament along the bile duct), No. 12p (in the hepatoduodenal ligament along the portal vein), and No. 13 (posterior head of the pancreas lymph node) for cancer invading the duodenum (D2+No. 13). Metastases to the Nos. 12b, 12p, and 13 nodes, which are not included in the regional lymph nodes for gastric cancer, should usually be classified as M1. However, since the Nos. 12b, 12p, and 13 nodes are among the regional lymph nodes for cancer of the duodenum according to the TNM classification and the Japanese Classification of Gastric Carcinoma 15th edition, these should be regarded as regional lymph nodes once gastric cancer invades the duodenum.
Dissection of No. 16 (abdominal aortic lymph node) after neoadjuvant chemotherapy for cancer with extensive lymph node involvement (D2+No. 16) (CQ5-1).
