[{'content': 'Marker for testicular tumor is \nSelect and explain. \nA. Beta hCG, B. Acid phosphatase, C. Alkaline phosphatase, D. Alpha fetoprotein', 'role': 'user'}, {'content': 'Answer: A \nExplanation: 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 b hCG and AFP are markers for testicular Ca, but if we have to choose one option, we would go for b 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)', 'role': 'assistant'}]
