Differences in Protein Expression and Gene Amplification of Cyclins between Colon and Rectal Adenocarcinomas

Table 5

Gene amplification. Variables that showed a significant difference between rectal cancers and colon cancers (results of binary logistic regression analysis on 403 patients).

Variable	Highest in rectum or colon	P-value	OR	95% CI for OR
Cyclin A2 amplification	Rectum	𝑃<.001	23.286	[7.316; 74.119]
Cyclin B1 amplification	Rectum	P = .008	8.056	[1.718; 37.781]
Cyclin D1 amplification	Colon	𝑃<.001	0.005	[0.001; 0.017]
Cyclin E amplification	Rectum	𝑃<.001	5.248	[2.417; 11.395]
Age at surgery	Colon	P = .017	0.955	[0.919; 0.992]
