Biomarker

 bladder cancer (23434148)

• Engrailed-2 (EN2) transcription factor is expressed in, and secreted by, bladder cancer cell lines and patient tumour specimens, justifying an evaluation of urinary
• EN2 as a diagnostic biomarker in bladder cancer using archived samples from an established biospecimen collection.
• In patients with NMIBC, urinary EN2 was detected in most cases with an overall sensitivity of 82% and specificity of 75%.
• The sensitivity for stage Ta and T1 tumours was 71% and 76%, respectively, and 94% for stage T2+ tumours. This compares favourably with existing markers.
• The sensitivity for tumour grades 1, 2 and 3 was 69%, 78% and 87%, respectively.
• Urinary EN2 has the potential to be a more sensitive and specific protein biomarker for NMIBC than currently available tests.
