Detection of uroplakin Ⅱ mRNA positive cells in peripheral blood of patients with urothelial cancer / 中华泌尿外科杂志

ABSTRACT

Objective To evaluate the role of detecting circulating UP Ⅱ mRNA positive cells in patients with transitional cell carcinoma (TCC). Methods Expression of UP Ⅱ mRNA was examined with nested reverse transcriptase polymerase chain reaction (RT PCR) assay. Results UP Ⅱ mRNA positive cells were detected in 0% (0/26) of patients with superficial urothelial cancers (pT a～1 N 0M 0), 20.8% (5/24) of patients with invasive cancers (pT 2～4 N 0M 0), 50.0% (1/2) of regional node positive patients (pN 1～2 M 0),and 100.0% (2/2) of patients with distant metastases. Positive rates increased with tumor extension ( P
