Details of Patients With Colonic Carcinoma

Case No.	Site of Operation	Pathologic Report	Tumor Staging	No. of Lymph Nodes Removed, Positive/Total
1	Cecum	Right colon resection: moderately differentiated invasive adenocarcinoma of the cecum arising in the tubulovillous adenoma. The tumor extends deeply into but not entirely through the muscularis propria. Free margins.	T2N1	2/18
2	Sigmoid colon	Sigmoid colon, segmental resection: moderately differentiated colonic adenocarcinoma invades just through the muscularis propria, with a micrometastasis to 1 of the 17 mesenteric lymph nodes. The margins of resection are uninvolved.	T3N1	1/17
3	Ascending colon	Right colonic adenocarcinoma: high-grade carcinoma with poorly differentiated sessile fungating tumor; tumor invades the submucosa and the muscularis propria but does not break though the structure and does not involve pericolonic adipose tissue.	T2N0	0/18
4	Terminal ileum, cecum, ascending colon	Sessile tubular adenocarcinoma of the colon, conventional type, moderately differentiated. Four other separate small tubular adenomatous colonic polyps were identified in the specimen. Twenty-eight regional mesenteric lymph nodes were examined and found to be tumor free.	T1N0	0/28
