Comment:

Answer D

The incidence of testicular cancer is 10 per 100,000 and 1%–2% are bilateral. Although ultrasound (US) of the testes has a sensitivity of almost 100% MRI is still more sensitive and specific but its cost-effectiveness over US is not justifiable. The IGCCCT (International Germ Cell Cancer Collaborative) prognostic-based staging system utilises AFP, HCG and LDH to determine different prognostic groups for metastatic tumours and the TNM classification uses tumour markers for their staging S groups
