Ki-67 Labeling Index in Primary Invasive Breast Cancer from Sudanese Patients: A Pilot Study

Table 5

The relationship between tumor grade and dichotomized Ki-67 Labeling Index (LI) using 10% as cutoff value in the studied patients.

		Tumor grade
		2	3
Ki-67 LI (MIB-1)	Low (immunostaining < 10%)	18 (90%)	25 (59.5%)
	High (immunostaining ≥ 10%)	2 (10%)	17 (40.5%)
	Fisher's Exact Test	P = 0.019
