The correlation analysis of HA, CD44, BRCA1, and BRCA2 showed only one strong correlation, BRCA1 and BRCA2 in breast cancer (r = 0.7; p < 0.0001), while in the case of colorectal cancer this correlation was much weaker (r = 0.5; p = 0.02). This evidence concerns the gene CD44 and colorectal cancer.
