"Bladder cancer patients in COL5A2 low expression group were associated with better invasiveness (P < .0001) tumor grade (P=.001) T staging (P < .0001) N staging (P = .002) and a trend of better M staging (P = .053) than those in COL5A2 high expression group. These results indicated that COL5A2 might promote the progression of Bladder Cancer cells."xsd:string
