Impact of density of schistosomal antigen expression in urinary bladder tissue on the stratification, cell type, and staging, and prognosis of carcinoma of the bladder in Egyptian patients

Table 3 Intensity of schistosomal antigen expression in different studied groups (580 patients)

Diagnosis	No. of cases	No. of positive cases	% of positive cases	Intensity of schIstosomal antigen expression in tissue
Diagnosis	No. of cases	No. of positive cases	% of positive cases	No antigen	Light	Moderate	Strong

Comments: 1- SCC was 100% positive for intensity of antigen expression.
2- The number and percentage of degrees of intensity of antigen expression were calculated in positive cases only.
3- Total number of positive cases in urothelial carcinoma were 316 out of 515 (61.5%).
