E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The primary aim of this proposal is to verify modification in the rating neurological scale adopted and to estimate progression free survival (according to an automated volumetric MRI analysis) in patients with not total resectable, disabling or disfiguring plexiform fibromas (see inclusion criteria) expressing c-KIT and treated with Imatinib mesylate. |
Primario: determinare la risposta al trattamento target sperimentale tramite MRI. |
|
E.2.2 | Secondary objectives of the trial |
Secondary aims include: 1) the evaluation of toxicity during the treatment graded according to NCI CTCAE v 3.0 2) to assess whether tumor specimens harbouring microdeletion of the NF1 gene (constitutional or aquired) show specific characteristics which can be correlated with the patients' response to the treatment; thus allowing the setting of more tailored treatment of NF1 microdeleted patiens that; despite beeing a minority of all NF1 patients, has an enhanced risk to develop tumors (De Raedt et al., 2003); 3) to analyze constitutional DNA mutation in order to assess whether there are correlations between genotype, the risk of developing large neurofibromas, and tumor rensponse to drug; 4) to assess whether previously described increase in the serum levels of SCF. |
Secondari: determinare la tossicità durante il trattamento; determinare la modificazione delle scale di deficit neurologico e di qualità di vita durante il trattamento; determinare se i pazienti con sindrome da microdelezione del gene NF1 e con tumore abbiano caratteristiche specifiche che possano essere correlabili alla risposta al trattamento; determinare la variazione dei livelli serici del ligando di c-KIT (SCF) durante il trattamento. |

E.3 | Principal inclusion criteria |
clinical diagnosis of NF1 according US National Institute of Health Consensus criteria, age at entry >3 < 65, and the presence of a measurable disabling or disfiguring plexiform neurofiroma that is not amenable to total surgical resection. Disabling PNF is defined as a tumor causing motor weakness by compression of the spinal cord or pain due to infiltration of spinal roots or limitation of limb mobility due to local mass effect. Disfiguring PNF is defined as an infiltranting tumor in the head and neck region with major cosmetic impairment, resulting in distress to the patient. Patients have to have a Lasky (children < 10 years) or Karnofsky (patients > 10 years) performance levels > 50. Radiographic progression is not a necessity for patient entry. |
•diagnosi clinica di neurofibromatosi di tipo 1 in accordo con i criteri consenso del US National Institute of Health; •età di ingresso nello studio compresa tra 3 e 65 anni; •presenza di almeno un neurofibroma plessiforme (PNF) disabilitante o sfigurante il paziente, e localizzazione del tumore tale da rendere la rimozione chirurgica difficilmente praticabile. Un PNF viene definito disabilitante quando il tumore causa deficit motorio o dolore per compressione delle vie nervose o limitazione funzionale dovuta ad un effetto massa locale. Un PNF è definito sfigurante quando il tumore localizzato in testa e nel collo provoca un danno estetico maggiore al paziente. •indici di Lasky (bambini con meno di 10 anni) o di Karnofsky (pazienti con più di 10 anni) >50; •esame istologico probante la diagnosi di neuro fibroma plessiforme, disponibilità di tessuto tumorale per l’analisi l’espressione di c-KIT l sul tumore. •bilirubina totale <1,5 x ULN, SGOT e SGPT <2.5 x UNL, creatinina <1,5 x ULN, ANC> 1,5 x 109 / L, piastrine> 100 x 109 / L; •test di gravidanza negativo entro 7 giorni prima di iniziare la somministrazione del farmaco in studio per le pazienti di sesso femminile in età fertile; • consenso informato scritto. |
|
E.4 | Principal exclusion criteria |
Patients undergoing radiation,chemotherapy, hormonal therapy, directed to the tumor or immunotherapy were excluded from partecipation. Other exclusion criteria are the presence of an active optic glioma or other tumor requiring radiation or chemotherapy. |
• pazienti senza altri tumori maligni primari da meno di 5 anni, eccetto i casi in cui il tumore maligno primario non sia attualmente né clinicamente significativo e non richieda un intervento attivo, o il tumore maligno primario sia un cancro delle cellule basali della pelle o un carcinoma in situ della cervice. L’esistenza di una qualsiasi altra malattia maligna non è permessa; • pazienti con problemi cardiaci di grado III/IV, come definiti dai criteri di New York Heart Association. (cioè, insufficienza cardiaca congestizia, infarto miocardico entro 6 mesi dall’inizio del trattamento); • pazienti con nota metastasi al cervello; • ;pazienti sottoposti a chemioterapia nelle 4 settimane (6 settimane per nitrosourea o mitomicina-C) precedenti l’ingresso nello studio, a meno che la malattia stia progredendo rapidamente; • pazienti che hanno precedentemente ricevuto radioterapia superiore al 25% del midollo osseo; • pazienti che hanno subito un importante intervento chirurgico nelle 2 settimane precedenti l'ingresso nello studio. |
