p27^kip1 expression in human colorectal cancers

Dukes	No. of p27kip1 expressing tumors			% of p27kip1 expressing tumors
	+	−	Total	+	−	Total
A	9	2	11	82	18	100

p27^kip1 expression in human colorectal tumors with different stages of malignancy, from Dukes A–D. As in Table 3, the number of tumors positive and negative for nuclear p27^kip1 staining are shown under + or −, respectively. The number of tumors examined for each Dukes stage is shown under total. The total number of tumors examined is regarded as 100%, and the percentage of nuclear p27^kip1 staining positive and negative tumors is shown as percentage under + or −, respectively for each group of tumors (Dukes A–D).
