Stage IVS neuroblastoma.
This is a review of the findings in 10 cases of stage IVS neuroblastoma, that have been observed in the First Surgical Department of Hokkaido University Hospital. The patients under the age of 1 yr in stage IVS neuroblastoma have a favorable prognosis; the survival rate was 70%. The regressions were histologically confirmed as maturation of the neuroblastoma cells to ganglioma cells. The lymphocyte counts and T-cell function were well maintained in the surviving patients but both were markedly reduced in the patients who later died. The treatment should be conservative so that immune mechanisms are not inhibited and should be withheld until respiratory failure or progressive signs toward stage IV are identified.
