? La respuesta al esquema de tratamiento definida por el porcentaje de pacientes con la desaparición de todas los síntomas ? La respuesta estimada por los padres ? La respuesta con respecto al cada escalón de tratamiento ? Evaluar el número de recurrencias de SOM/SOD ? Establecer el porcentaje de SOM/SOD asociados a neuroblastoma ? Describir los pacientes con neuroblastoma en según estadíos INSS y la necesidad de tratamiento quimioterapico (para los neuroblastomas) ? Evaluar la carga administrada a los los pacientes como: ? Comparar los pacientes SOM-NBpos y SOM-NBneg ? Estudiar prospectivamente el resultado neurológico y neuropsicológico de los pacientes con SOM/DES ? Estudiar la calidad de la vida de los pacientes ? Correlacionar el resultado a largo plazo y la calidad de vida con edad al diagnóstico, ? Comparar resultados neurológicos y congnitivos ?

E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
?Children with newly diagnosed OMS/DES either NB-pos or NB-neg. Three out of the following four components are necessary for the diagnosis of OMS/DES: - Opsoclonus or ocular flutter (but not nystagmus) - Ataxia and/or myoclonus - Behavioural change and/or sleep disturbance - Neuroblastoma ?Age 6 months or over up to less than 8 years (< 8th birthday) ?Treatment start with the standard corticosteroid treatment with dexamethasone pulses as proposed by the guidelines given in this trial protocol ?In patients with presumed NB-neg OMS/DES, neuroblastoma must be excluded according the guidelines of this trial ?Documented informed consent for treatment and enrolment in the trial by parents / legal representatives . |
?Niños con SOM/SOD de nuevo diagnóstico bien NB-pos or NB-neg ?Edad mayor de 6 meses hasta 8 años (< 8º cumpleaños) ?Comienzo del tratamiento con el tratamiento corticoideo estandar con pulsos de dexametasona como se propone en las recomendaciones de este ensayo clínico ?En los pacientes con sospecha de SOM/SOD NB-neg, debe excluírse Neuroblastoma de acuerdo las recomendaciones de este ensayo clínico ?Documentación de Consentimiento informado para el tratamiento e inclusión en el ensayo clínico por los padres o representantes legales |
|
E.4 | Principal exclusion criteria |
? Patients with opsoclonus, myoclonus or ataxia caused by other identified disease (e.g. current active CNS infection, neurometabolic disorder or demyelination). An identified viral precursor is not an exclusion criterion. ? prior or parallel use of chemotherapy (other than required for treatment of the neuroblastoma) ? Corticoid steroid for OMS/DES or other reasons lasting 14 days or more immediately before treatment start according the standard treatment proposed (treatment with corticosteroids for less than 14 days will be allowed) ? contre-indication of use of one of the experimental study drug (cf Summary of Product Characteristics used in this study) |
? Los pacientes con opsoclono, mioclonias o ataxia causada por otra enfermedad (p.ej. una infección activa del SNC, trastornos neurometabólicos o desmielinización). Una determinación de una infección viral no es un criterio de exclusión. ? Uso de quimioterapia previo o en paralelo (distinta de la requerida para el tratamiento del Neuroblastoma) ? Tratamiento corticoideo para SOM/SOD o por otras razones durante 14 o más días inmediatamente antes del comienzo del tratamiento estándardizado propuesto (se permitirá el uso de corticoides durante menos de 14 días) |
