Moreover, significant variation was found relating CD117/KIT intensity score to tumoral schistosomiasis association with a P value of 0.001, as all the six cases with strong staining (dark brown color, score 3) were included in the bilharzial urinary bladder carcinoma group and all the 13 cases that were weakly stained (score 1) were included in the control group. Here, KIT is linked to schistosomiasis.
