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 2 Density of schistosomal antigen expression in different studied groups (580 patients)

Diagnosis	No. of cases	No. of positive cases	% of positive cases	Density of schistosomal antigen expression in tissue
				Not detected	Low	Moderate	High
				0% 0	1%-25%	26%-50%	51%-100%
Control BPH	25	0	0%	25 (100%)	0	0	0
Control IC	5	0	0%	5 (100%)	0	0	0
SCC	30	30	100%	0 (0%)	0	8 (26.7%)	22 (73.3%)
Urothelial Carcinoma Ta	40	15	37.5%	25 (62.5%)	12 (80%)	3 (20.0%)	0 (0%)
Urothelial Carcinoma T1	50	31	62%	19 (38.0%)	14 (45.2%)	9 (29.0%)	8 (25.8%)
Urothelial Carcinoma T2-4	425	270	63.5%	155 (36.5%)	57 (21.1%)	120 (44.4%)	93 (34.5%)

Comments: 1- SCC was 100% positive for density of antigen expression.
2- The number and percentage of degrees of density 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%).
