41 - parathyroid and adrenal surgery mcqs - 2
9q: which of the following is a good prognostic factor for neuroblastomas ?
a. N-myc amplification
b. RAS oncogene

d. translocations
answer: c . hyperdiploidy . if the age of the baby is less than or equal to one year at the time of presentation then it is a good prognostic factor , but if the age is greater than 1 year then it is a bad prognostic sign for neuroblastomas. stage 1,2A,2B,4S are all favourable prognosis. stage 3 , 4 are bad prognostic factors. evidence of schwannian stroma and gangliocytic differentiation is a good prognostic sign and absence of it is a bad prognostic sign. presence of intratumoral calcification is a good prognostic sign.
