Alpha-fetoprotein (AFP) is elevated in all of the following EXCEPT:
- A Hepatocellular carcinoma
- B Yolk sac tumour (endodermal sinus tumour)
- C Hepatic regeneration (cirrhosis)
- D Seminoma ✓
Correct answer: D. Seminoma
Explanation
Pure seminoma does not secrete AFP; AFP elevation in a testicular germ cell tumour suggests a non-seminomatous component (yolk sac tumour, embryonal carcinoma). HCC and yolk sac tumours are classic AFP-producing tumours. Cirrhosis causes mild AFP elevation due to hepatocyte regeneration. AFP >400 ng/mL in a cirrhotic patient is diagnostic of HCC.
