The prostate-specific acid phosphatase (abbreviated PAP , . Of English prostatic acid phosphatase ) is a glycoprotein - enzyme , which is produced by mammals and fish. It is produced in the prostate in humans . Beyond belonging to the acid phosphatases , nothing precise is known about its function. The laboratory value proves the activity of the prostate tissue and can therefore be used as a control when it is removed.
laboratory
In diagnostics, PAP is mainly used to monitor the progression of prostate cancer . It serves here with the more important prostate-specific antigen (PSA) as a tumor marker . Since increased PAP concentrations in the blood serum are measured not only in malignant but also in benign diseases of the prostate, the PAP is regarded as an organ-specific marker and not as tumor-specific.
rating
In healthy men the concentration is less than 2.0 ng / ml in the serum. Values above 3.5 ng / ml are pathological. Persistent pathological values during therapy for prostate cancer indicate therapy failure.
Nonspecific PAP elevations in the serum occur primarily with benign prostatic hyperplasia , but also with or after manual manipulation of the prostate (palpations, catheterization) or with inflammation of the prostate.
use
Recent research also suggests that PAP could be used as a highly effective pain reliever.
