Detection of HPV and the role of p16INK4Aoverexpression as a surrogate marker for the presence of functional HPV oncoprotein E7 in colorectal cancer

Table 1 Location of the tumors throughout the colon in correlation to the presence of HPV.

	HPV positivity	n	%	% total
Proximal	caecum	6	18.2	39.4
	hepatic flexture	3	9.1
	colon ascendens	1	3.0
	right hemicolon	3	9.1
Distal	rectosigmoid	4	12.1	30.3
	sigmoid	5	15.2
	colon descendens/sigmoid	1	3.0
Rectum		10	30.3	30.3

N = number of HPV positive samples, % = percentage of HPV positive samples per location separately, total %: percentage of HPV positive samples in proximal, distal and rectal tumors.
