In addition, 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 schistosomiasis-related urinary bladder carcinoma group and all the 13 cases that were weakly stained (faint or light blue color, score 1) were included in the control group (Fig. 1). Here, KIT is linked to schistosomiasis.
