RESUMEN
OBJECTIVE: To explore multi-drug resistance (MDR) of bladder cancer for the intravesical instillation. METHODS: Using immunohistochemical staining, in 44-case human bladder cancer cells, the expressions of P-glycoprotein (P-gp), glutathione S-transferase (GST-pi) and topoisomerase (TOPO-II), were detected to find out the resistance to drugs. RESULTS: P-gp had a higher expression in 54.5% cases. GST-pi had no or a lower expression in 65.9% cases. TOPO-II had a higher expression in 29.5% but a lower expression in 65.9% cases. CONCLUSION: Detecting the factors of MDR in bladder cancer cells could help to choose drugs for intravesical chemotherapy.
