膀胱癌之生物標記及其檢測方法

The present invention provides a bladder cancer biomarker and its testing method. The biomarker contains at least one selected from of a group consisting of apolipoprotein A1 (APOA1), apolipoprotein A2 (APOA2), peroxiredoxin 2 (PRDX2), heparin cofactor 2 precursor (HCII), and serum amyloid A-4 protein (SAA4), existed in the urine specimen of a testee. The expression intensity of the biomarker can assist in diagnosing bladder cancer and determining invasion level of cancer cells so as to facilitate understanding of the conditions of patients with bladder cancer, thereby arranging an optimized treatment to achieve the best therapeutic effect.
