Neuroblastoma (NB), ganglioneuroblastoma intermixed (GNBi) and
ganglioneuroblastoma nodular (GNBn) are neuroblastic tumors that present with a
wide range of symptoms and variable prognoses. We retrospectively reviewed the
pretreatment clinical (age, sex and tumor stage) and biological (MYCN
amplification; and levels of lactate dehydrogenase, ferritin and neuron-specific
enolase) characteristics of 279 patients who were diagnosed with pathologically
confirmed NB and GNB from January 2005 to December 2015. The median age at
diagnosis increased with grade of differentiation (NB: 28.9 months; GNBn: 38.4
months; GNBi: 47.5 months; p < 0.01). NB patients were more frequently diagnosed
with adrenal tumors and had a higher prevalence of abnormal serum ferritin at the
time of diagnosis (60.0% vs. 40.0% vs. 12.0%, P<0.001), NSE (96.0% vs. 93.0% vs.
81.0%, P=0.013) when compared with GNBn and GNBi patients. The prevalence rates
of disseminated tumors and MYCN amplified tumors were lower in the GNBi group
than in the GNBn and NB groups (13.0% vs. 25.0% vs. 44.0%, P=0.002; 0 vs. 14.0%
vs. 26.0%, P=0.032, respectively). The overall survival (OS) of patients with GNB
was significantly better than that of patients with NB (GNBi: 100%, GNBn:
74.5±11.4%, NB: 50.8±4.5%, respectively; P<0.01). Our study revealed that both NB
and GNB have a wide range of presentations, and clinicians should be aware of
both typical and atypical symptoms and signs. Children with GNB (especially GNBi)
were more likely to present favorable prognostic factors than their NB
counterparts, which consequently lead to better outcomes and longer survival for
these patients.
