Prognostic impact of cytogenetic abnormalities in children and adolescents with mature B-cell non-Hodgkin lymphoma: A report from the Japanese Pediatric Leukemia/Lymphoma Study Group (JPLSG).

Abstract:

:Little information is available on cytogenetic abnormalities and their prognostic importance in childhood mature B-cell non-Hodgkin lymphoma (B-NHL). We performed a review of 79 abnormal karyotypes in childhood B-NHL treated by a uniform protocol. Del(17p) was independently associated with significantly inferior event-free survival in Burkitt or Burkitt-like lymphoma. The adverse prognosis of MYC/8q24 rearrangement, +7q or del(13q), was not observed, which had been suggested as risk factors in FAB/LMB96. Our results imply the possible existence of a biological difference among ethnicities and should be useful to narrow down the gene causing poor prognosis in childhood B-NHL.
