The gold standard for prostate cancer screening

Malignant tumors such as prostate cancer will seriously affect the health of patients after they occur. Such diseases have a relatively high mortality rate after they occur. Therefore, we hope that every patient can go to a regular hospital for examination in time after becoming ill. Let us learn about the gold standard for examining prostate cancer.

Laboratory tests
1. The serum prostate-specific antigen (PSA) is elevated, but in about 30% of patients, the PSA may not be elevated, but only fluctuates within the normal range (normal range <4.0ng/ml). If the PSA measurement is combined with the digital rectal examination (DRE), the detection rate will be significantly improved.
2. Elevated serum acid phosphatase is related to prostate cancer metastasis, but lacks specificity. In recent years, radioimmunoassay can improve its specificity. Prostate acid phosphatase monoclonal antibody and prostate antigen assay need to improve their specificity. Acid phosphatase is elevated in stage C prostate cancer, and it is also elevated in lymph node metastasis. If it continues to rise, there is definitely bone metastasis. Serum acid phosphatase, those with elevated prostate acid phosphatase will decrease after surgery, which is a sign of a better prognosis. The acid phosphatase of prostate cancer in the capsule is secreted by prostate cells and excreted through the prostate duct. In prostate cancer, the acid phosphatase produced by cancer cells has no duct to be discharged or the duct is blocked by cancerous lesions, and the enzyme is absorbed into the blood circulation, resulting in elevated acid phosphatase.
