Primary Outcome Measures
NameTimeMethod
Main Objective: To evaluate efficacy of TREO/MEL high dose chemotherapy conditioning + aPBSCT in patients with rNB and rES in terms of response rate defined as absence of progression* in 3 months.;Secondary Objective: •To evaluate occurrence of veno-occlusive disease/sinusoidal obstruction syndrome (VOD/SOS) 4 weeks after high dose chemotherapy. <br>•To evaluate safety and tolerability of high-dose chemotherapy TREO/MEL regimen and aPBSCT in children, adolescents and young adults with rES or rNB after FU 1 Visit (4 weeks after high-dose chemotherapy with TREO/MEL). <br>•To evaluate time to progression in the study population. <br>•To evaluate overall survival (OS) of the study population.<br>•To compare the study population survival data trends with available historical data.;Primary end point(s): Primary endpoint of efficacy<br>•Absence of the primary disease progression 3 months after aPBSCT.;Timepoint(s) of evaluation of this end point: <br>3 months after aPBSCT
Secondary Outcome Measures
NameTimeMethod
Secondary end point(s): Secondary endpoints<br>•Occurrence of VOD/SOS in each patient. <br>•Occurrence of organ toxicity grade III or IV according to CTCAE (v4.0)* (with special interest to cardiac, renal, hepatic toxicity) <br>*Common Terminology Criteria for Adverse Events (CTCAE), v4.0<br>•Time to progression (TTP). <br>•Overall survival (OS). ;Timepoint(s) of evaluation of this end point: During the whole course of the clinical trial for occurence of VOD/SOS, occurence of organ toxicity grade III or IV and TTP.<br>In 3, 6, 12, 18 and 24 months for OS
