MYC and non-Hodgkin lymphoma: Otherchallenges include presence or absence of cytogenetic abnormalities such as 13q− and 7q+, which could be useful for prognosis, but there remains alack of consistent cytogenetic abnormalities other than c-myc inchildhood NHL for use in FISH or PCR [28].Thus, the current study could potentially be applicable in assessing PD/MRD throughIgVH oligomer pools in a PCR assay that does not rely on primary diagnostictissue for a specific tumor marker.
