[{'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\n\nBeta HCG\nAlpha feto protein (AFP)\nLDH\n\n\nBeta HCG - concentration is increased in both seminoma & non-seminoma\nAFP - concentration is increased in only non-seminoma\nLDH - is increased in both, it is not as specific as either of AFP or Beta HCG.\nSo 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\n\nSome other tumor markers for testicular Ca (but not imp.) are\n\nPlacental alkaline phosphates (PLAP)\nGamma-glutamyl transpeptidase (GGT)', 'role': 'assistant'}]
