The findings showed that P36 located mainly in the cytoplasm with a small amount in cellular membrane and its total positive rate was 53. 3%. In patients whose tumor cells were deeply infiltrated and poorly differentiated, and who relapsed and died, the positive staining was stronger. The result indicates that P36 is an important molecule closely related to trans formation of bladder cancer. It is an essential marker for judging the malignancy and prognosis of bladder cancer.展开更多

Point mutations in c-myc were detected in cases with high grade and proliferation index. Mutated K-ras proto-onco- gene profiles were detected in 17 (21%) tumoral spiecemens that examined. Tumor specimens were also showed hypermethylated promoter domain for the SFRP2, MGMT tumor supressor genes. These findings showed the combine effect of mutated c-myc and K-ras oncogene and epigenetic inactivation of tissue specific tumor supressor genes (TS) play a crucial role in tumor progression and recurrence in UN carcinogenesis.展开更多
