title: Expression of KAI1/CD82 and MRP-1/CD9 in transitional cell carcinoma of bladder.
abstract: The expression of KAI1/CD82 and MRP-1/CD9 in transitional cell carcinoma of bladder (TCCB) and its clinical significance were investigated. Immunohistochemistry was used to detect KAI1/CD82 and MRP-1/CD9 protein expression in 52 TCCB specimens. Correlation between the expression of KAI1/CD82 and MRP-1/CD9 to clinicopathologic factors was statistically analyzed. The results showed that the positive rate of KAI1/CD82 and MRP-1/CD9 in TCCB was 50% and 61.5%, respectively. The MRP-1/CD9 and KAI1/CD82 expression was significantly associated with grade of TCCB (P<0.05), but no correlation was found between MRP-1/CD9 or KAI1/CD82 expression and clinical stage of TCCB (P>0.05). The expression level of MRP-1/CD9 and KAI1/CD82 in recurrent TCCB samples was lower than that in non-recurrent samples (P<0.05). Meanwhile, the correlation between the KAI1/CD82 expression and MRP-1/CD9 expression was statistically significant (r=0.316, P<0.05). It was concluded that KAI1/CD82 and MRP-1/CD9 expression may be important prognostic indicators and potentially useful for assessing the biological behavior of TCCB.
