Abstract

The early diagnosis of bladder cancer is important for effective treatment of the disease. This study aimed to evaluate the nuclear matrix protein 22 (NMP 22), soluble epithelial cadherin (E-cadherin), cathepthin-D and total protein with clinico-pathological features of bladder cancer, and to determine the relation between each marker and tumor progression after treatment. The study includes 65 patients with bladder cancer, 14 benign urinary diseases and 11 healthy volunteers. Patients were categorized according to bilharzial infestation, T stage, tumor grade, size and the presence of lymph node metastasis. Forty patients were followed for disease progression after surgery. There was a significant increase of NMP22, E-cadherin, cathepthin-D and total protein detected in cancer group compared to healthy and benign groups. It was found that NMP 22 and E-cadherin had highest sensitivity (84.4, 76.9 %, respectively) while, total ddedprotein showed highest specificity (77.4 %). Tumor size correlated with urinary NMP22 (r = 0.3, p = 0.02), although, E-cadherin, cathepsin-D and total protein correlated with tumor size (r = 0.3, 0.28, 0.2; p = 0.01, p = 0.01, 0.04, respectively) and lymph node metastasis (r = 0.32, 0.34, 0.2; p = 0.003, 0.005, 0.04, respectively). Elevated pretreatment urinary NMP22, E-cadherin and total protein levels was associated significantly with bladder cancer recurrence (p = 0.02, 0.001, 0.005, respectively). In conclusion, determination of urinary NMP22, E-cadherin and total protein in bladder cancer patients or persons at risk of developing bladder cancer will help in early detection of the disease and prediction of recurrence. The use of a combination of tumor markers is markedly useful than the assessment of single one.
