Beta-hCG is a tumor marker most characteristically elevated in which conditions?

• A. Hydatidiform moles and choriocarcinomas
• B. Prostate cancer
• C. Pancreatic cancer
• D. Ovarian cancer

Answer: (A)

Beta-hCG is produced by placental trophoblastic tissue, so its levels rise when trophoblastic cells proliferate abnormally or become malignant. Hydatidiform mole involves abnormal placental tissue with extensive trophoblastic proliferation, leading to markedly elevated beta-hCG. Choriocarcinoma is a malignant tumor of trophoblastic origin that secretes large amounts of beta-hCG. These two conditions are the classic scenarios where beta-hCG becomes a characteristic tumor marker. Other cancers listed do not typically cause such marked elevations in beta-hCG.
