CASP3 and colorectal carcinoma: Semi-quantitative analysis of Ki-67 staining and active Caspase-3 staining on the CRC TMAs did not reveal a significant correlation (Spearman correlation analysis: rho=0.007, P=0.95); however, there was a positive correlation in the CT versus untreated group (rho=0.10, P=0.50 versus rho=−0.03, P=0.82) albeit none of these correlations were statistically significant.
