Which tumor markers are used to measure treatment response in testicular cancer?

CA 125 and PSA
B-HCG and a-FP
HER2 and BCR-ABL
AFP and CA 19-9

The correct answer is: B-HCG and a-FP

B-HCG (Beta-human chorionic gonadotropin) and a-FP (alpha-fetoprotein) are specific tumor markers used to monitor treatment response in testicular cancer. In particular, these markers are crucial in the diagnosis, treatment planning, and follow-up of patients with different types of testicular tumors. Beta-HCG is often elevated in non-seminomatous germ cell tumors, while alpha-fetoprotein is primarily associated with yolk sac tumors and non-seminomatous types as well. After treatment, decreases in the levels of these markers indicate a positive response to therapy, while persistently high or rising levels could suggest disease progression or residual disease. Monitoring these markers is vital for evaluating the effectiveness of the treatment and for detecting any recurrence early. Thus, their role is essential in the comprehensive management of patients diagnosed with testicular cancer.
