Question

Quizplus · Accepted Answer

During treatment for prostatic cancer, prostate-specific antigen (PSA) is a useful serum marker. PSA is produced by normal as well as malignant prostate cells and its level is elevated in the blood of patients with prostate cancer. Monitoring PSA levels can help to determine the response to treatment and detect any recurrence of the disease. Human chorionic gonadotropin (A) and alpha-fetoprotein (B) are serum markers used in the management of testicular cancer and hepatocellular carcinoma, respectively. Luteinizing hormone (D) is a hormone that stimulates testosterone production by the Leydig cells in the testes and is not typically used as a serum marker in the management of prostate cancer.
