DOCK4 and carcinoma: Analysis revealed a significant association between DOCK4 expression and histological tumour type (p = 0.002) and tumour grade (p = 0.004) with 86.4% grade 3 and 77.3% grade 2 ductal carcinomas expressing moderate/high DOCK4 (as opposed to 62.5% grade 1 carcinomas), but no association with ER status (positive versus negative, p = 0.185) or lymph node status (involved versus not involved, p = 0.15).
