In more advanced stages of both types of bladder cancer, MMP3 was similar to MMP9 in its significant elevation than controls both in schistosomal bladder cancer (0.166 ng/ml) and non schistosomal bladder cancer groups (0.235 ng/ml) and this elevation was higher in non schistosomal bladder cancer patients (Table 2) and ( Figure 2). This evidence concerns the gene MMP9 and urinary bladder carcinoma.
