What molecular subgroup has the best prognosis in a child diagnosed with medulloblastoma?
Sonic hedgehog (SHH)
The correct answer is Wnt.
WNT subgroup of medulloblastomas has the best prognosis of any subgroup; five year survival rate is over 95%. There is no male or female predominance. This subgroup is least common of the four subgroups, accounting for only about one in ten diagnoses.
The SANS Lifelong Learning Exams was designed to enhance medical knowledge and self-assessment in neurosurgery, reinforce practice patterns, and recognize knowledge gaps. SANS exams offer 250 questions across specialties worth up to 24 CME.
