Prognosis
The chance of cure for neuroblastoma depends on the site and histological characteristics
of the tumour, the patient's age and the degree of tumour spread at the time
of diagnosis. For localized and well differentiated tumour in a child older
than 2 years, the survival rate is over 80%, whereas, if the tumour is widespread,
usually in infancy, the chance of survival is not good. Although there has been
much advance in treatment in the past decade, the results in treating the poor
prognostic group are still not satisfactory. New forms of treatment using bone
marrow transplants are under study.
