Role of Engrailed-2 (EN2) as a prostate cancer detection biomarker in genetically high risk men
نویسندگان
چکیده
Controversy surrounds the use of PSA as a biomarker for prostate cancer detection, leaving an unmet need for a novel biomarker in this setting; urinary EN2 may identify individuals with clinically relevant prostate cancer. Male BRCA1 and BRCA2 mutation carriers are at increased risk of clinically significant prostate cancer and may benefit from screening. Urine samples from 413 BRCA1 and BRCA2 mutation carriers and controls were evaluated. Subjects underwent annual PSA screening with diagnostic biopsy triggered by PSA > 3.0 ng/ml; 21 men were diagnosed with prostate cancer. Urinary EN2 levels were measured by ELISA and had a sensitivity of 66.7% and specificity of 89.3% for cancer detection. There was no statistically significant difference in EN2 levels according to genetic status or Gleason score. Urinary EN2 may be useful as a non-invasive early biomarker for prostate cancer detection in genetically high-risk individuals.

Purpose: Prostate cancer (PC) is the second most common cause of cancer related death in men. A number of key limitations with prostate specific antigen (PSA), currently the standard detection test, has justified evaluation of new biomarkers.

The aim of this study was to assess the relationship between pre-prostatectomy urinary Engrailed-2 (EN2), a transcription factor secreted by prostate cancer cells, with tumour volume and pathological characteristics in resected prostate specimens. First pass urine samples (10 ml) without prior prostatic massage were collected and stored at –80 ̊C. EN2 levels were measured using an enzyme-linked ...

Prostate cancer is the second leading cause of cancer death among men in the United States of America. However, the molecular mechanisms underlying the disease remain largely unknown. Therefore, the identification of tumor specific molecules that serve as targets for the development of new cancer drugs is considered to be a major goal in cancer research. The mouse Engrailed-2 (En-2) gene, which...

Despite significant advances in our understanding of the molecular pathology of bladder cancer, it remains a significant health problem with high morbidity and mortality associated with muscle-invasive bladder cancer (stages T2+), and high costs associated with the surveillance of non-muscle-invasive bladder cancer (NMIBC, stages Ta/T1/Tis). Moreover, current diagnostic biomarkers are suboptima...
