Marker for testicular tumor is –
Correct Answer: Beta hCG
Description: Tumor markers of Germ cell tumors of the testis
Beta HCG
Alpha feto protein (AFP)
LDH
Beta HCG - concentration is increased in both seminoma & non-seminoma
AFP - concentration is increased in only non-seminoma
LDH - is increased in both, it is not as specific as either of AFP or Beta HCG.
So both β hCG and AFP are markers for testicular Ca, but if we have to choose one option, we would go for β hCG as its seen in both seminomas as well as non-seminoma
Some other tumor markers for testicular Ca (but not imp.) are
Placental alkaline phosphates (PLAP)
Gamma-glutamyl transpeptidase (GGT)
