Urine Markers

There are more than 30 published biomarkers. Cytology has highest specificity, other markers have higher sensitivity.


Urovysion FISH
  • Detects increased copies of chromosome 3, 7, 17 and deletion of 9p21 (site of p16) (1) 
  • Sensitivity of 58%, 77%, 96%, 100% in grades 1, 2, 3 and CIS respectively (higher than cytology in all grades) (2)
  • FDA approved
  • Positive FISH after BCG was found to be 3.3 risk of progression/recurrence in one study. (11)



NMP22 (3) 
  • Available as POC or send out ELISA
  • Detects NMP22, a nuclear mitotic protein released from apoptotic cells
  • Sensitivity ranged of 67% (from 68.5% to 88.5%) and specificity of 75% (ranges from 65.2% to 91.3%)
  • False positives from hematuria, infection, stones, recent instrument
  • FDA approved

BTA (qualititative=BTA Stat; quantitative=BTA TRAK) (3,4)
  • Available as POC or send out ELISA
  • Detects human complement factor H related protein in urine
  • Sensitivity reported ranges of 62-68% while specificity reported around 73.6% 
  • False positives from hematuria, infection, prior BCG
  • FDA approved

GeneXpert Bladder Cancer ASSAY (6) 
  • A 90 minute test
  • mRNA's ABL1, CRH, IGF2, ANXA10, UPK1B
  • Overall sensitivity was 73% and specificity 90% if hematuria and 77% in surveillance population
  • 83% sensitivity for high grade bladder cancer

Cytology (5) 
  • Sensitivity 35%, specificity 94% overall
  • 58% up to 80% sensitivity for intermediate and high grade (5,8)
  • approximately 20% in low risk (8)

ImmunCyt/uCyt+
  • Looks at 3 monoclonal antibodies associated w/ UCC
  • 81% sensitivity, 75% specificity
  • False positives from stones, infection, BPH
  • Does not come in POC, requires 500cells to make diagnosis
  • FDA approved

AssureMDx
  • DNA methylation of 3 genes
  • 93% sensitivity, 83% specificity, NPV of 99.6%

Cxbladder (10)
  • Gene expression of 5 biomarkers
  • 93% sensitivity, 85% specificity
  • Includes biomarker for inflammation to reduce false positives

BladderChek

UROBEST

mRNA's overexpressed in bladder cancer are ABL1, CRH, IFG2, ANXA10, KRT20, AR, PIK3CA, UPK1b, UPK2, MGEA5.  (6) IGF-2 urine levels have been shown to be high in patient w/ bladder cancer. (7) GeneXpert uses mRNA testing capability.

URINE METABOLIC BASED BIOMARKERS
​Metabolic changes occur that are reflected in urine and early studies into these biomarkers have suggested a high sensitivity and specificity. (9)
