The prognosis of children with metastatic neuroblastoma (NB) > 18 months at diagnosis is dismal. Since the immune status of the tumor microenvironment could play a role in the history of disease, we evaluated the expression ofCD45,CD14,ARG1,CD163,CD4,FOXP3,Perforin-1(PRF1),Granzyme B (GRMB), andIL-10mRNAs in primary tumors at diagnosis from children with metastatic NB and tested whether the transcript levels are significantly associated to event-free and overall survival (EFS and OS, resp.). Children with high expression ofCD14,ARG1andFOXP3mRNA in their primary tumors had significantly better EFS. Elevated expression ofCD14, andFOXP3mRNA was significantly associated to better OS.CD14mRNA expression levels significantly correlated to all markers, with the exception ofCD4. Strong positive correlations were found betweenPRF1andCD163, as well as betweenPFR1andFOXP3. It is worth noting that the combination of high levels ofCD14,FOXP3, andARG1mRNAs identified a small group of patients with excellent EFS and OS, whereas low levels ofCD14were sufficient to identify patients with dismal survival. Thus, the immune status of the primary tumors of high-risk NB patients may influence the natural history of this pediatric cancer.
