Chou et al. (2014) found that there is a strong correlation between ARID1A expression loss and older age, right-sided tumors, larger tumor size, medullary morphology, high histological grade, BRAFV600E variation, and loss of mismatch repair protein expression (all P < 0.01), however, no significant association was found between loss of ARID1A expression and overall survival. This evidence concerns the gene ARID1A and neoplasm.
