Zinc/PSA Ratio as a Novel Biomarker for Prostate Cancer Detection
Zinc/PSA Ratio as a Novel Biomarker for Prostate Cancer Detection
Although Prostate Specific Antigen (PSA) is a useful marker for early detection of the prostate cancer, its specivity is not sufficient. Several PSA variations were defined in order to increase the specivity of the test, but they aren't much more effective than the PSA alone for detection of disease.
In older studies reported that, serum and prostatic tissue zinc levels decreased in prostat cancer disease.
In our study we aimed to establish the utility of serum zinc, PSA, free PSA/PSA (fPSA/tPSA), zinc/PSA, levels for early detection of the prostate cancer.
Inclusion Criteria:
Patients with LUTS and elevated serum PSA levels and/or suspicious rectal examination
Exclusion Criteria:
usage of zinc included drugs, older prostatic operations, older prostatic radiotherapy, older prostatic biopsies, chronic rectal diseases (anal fissure, hemorrhoid, etc..), PIN(prostatic intraepithelial neoplasia) and ASAP(atypical small acinar proliferation) in pathologic evaluation.
