A study on cases of resected gastric carcinoma with gross infiltrating the adjacent organs.

Should direct mesocolon invasion be included in T4 for the staging of gastric cancer?

“…In this study, we showed that the mesocolon was contiguous structure with the second highest rate of invasion by primary gastric cancer. Our results are consistent with several previous reports [5][6][7][8][9]. However, the UICC did not list the mesocolon as an adjacent structure to be considered in the staging of gastric cancer [2].…”

T4 Gastric Carcinoma: The Benefit of Non‐curative Resection

“…With regard to the invaded organ, the most frequent sites of invasion in this study were the colon/mesocolon, followed by the pancreas, liver, peritoneum and spleen. Two other studies, those of Saito et al 6 and Shirakabe et al , 7 reported that the pancreas was the most frequent site of invasion, followed by the mesocolon and colon. In patients with T4 gastric carcinoma, Dhar et al 8 reported that invasion of a particular organ had no effect on survival; Kodama et al 9 also did not find any survival benefit according to the organ invaded.…”

Combined resection of invaded organs in patients with T4 gastric carcinoma

“…With regard to the invaded organ, the most frequent sites of invasion in the current study were the pancreas, followed by the mesocolon, the peritoneum, colon, diaphragm, and liver. Shirakabe et al [8] have reported on a very large number of patients with invasion and similarly found the pancreas to be the most frequent site of invasion, followed by the mesocolon, colon, liver, and diaphragm.…”
