Tissue type	Total (n)	Low immunoreactivity score, n (%)^a	High immunoreactivity score, n (%)^a	Significance^b
HuR

Adenoma	38	11 (28.9)	27 (71.1)	<.0001
Adenocarcinoma	76	13 (17.1)	63 (82.9)	<.0001
TTP
Normal	82	10 (12.2)	72 (87.8)
Adenoma	42	33 (78.6)	9 (21.4)	.00019
Adenocarcinoma	82	65 (79.3)	17 (20.7)	<.0001
COX-2
Normal	81	70 (87.0)	11 (13.0)
Adenoma	41	16 (39.0)	25 (61.0)	<.0001
Adenocarcinoma	78	17 (21.8)	61 (78.2)	<.0001

Immunoreactivity score for each tissue was on a scale of 0 to 12 as indicated in Materials and Methods section; low immunoreactivity score distribution ranged from 0 to 6, and high immunoreactivity score distribution ranged from 7 to 12.
