Marker for testicular tumor is ?

Ans is 'a' ie Beta HCG Tumor markers of Germ cell tumors of the testis I) Beta HCG 2) Alpha feto protein (AFP) 3) 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 13 hCG and AFP are markers for testicular Ca, but if we have to choose one option, we would go for 13 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 phosphatase (PLAP) Gamma-glutamyl transpeptidase (GGT)
