Ki-67 Expression in CRC Lymph Node Metastasis Does Not Predict Survival

Table 2

Pattern of protein staining in tumour versus normal adjacent epithelium.

Protein marker	Immunoreaction
Ki-67		Positive (%)
CCR
NA^E	140	34 (24.3)	<0.001
Tumour	506	345 (68.2)
Lymph node
Normal	2	2 (100.0)	0.502^*
Metastasis	109	60 (55.0)

NA^E: normal adjacent epithelium;: total number of cases with and without expression of Ki-67; positive (%): total number of cases with expression of Ki-67 and respective percentage.
^*Comparisons were examined for statistical significance using Fisher’s exact test (when < 5).
