E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The present study aims to optimize the nuclear medicine therapeutic approach (radioiodine treatment) to metastatic DTC and to deepen the knowledge on 131I inefficacy. Lesion dosimetry and biological characterization are necessary for both purposes. We therefore propose a twofold path: • to investigate if dosimetry-based 131I administration may increase efficacy as compared to that obtained with fixed activity, with an acceptable toxicity in DTC patients with soft tissue and skeletal metastasis • to study if the mutational status, the gene expression and the variations of miRNA profiles before and after therapy of DTCs may be related to lesions’ refractoriness, even to personalized, 131I therapy |
Il presente studio mira ad ottimizzare e personalizzare la terapia medico-nucleare con radioiodio (131I), nonché ad approfondire le conoscenze sulla possibile inefficacia del trattamento. Proponiamo, quindi, un duplice obiettivo: • indagare se la somministrazione personalizzata di 131I basata sulla dosimetria possa aumentare l'efficacia terapeutica; • studiare se lo stato mutazionale, l'espressione genica e le variazioni dei profili di microRNA, prima e dopo la terapia con DTC, possano essere correlate alla refrattarietà delle lesioni, anche a seguito di terapia con 131I personalizzata |
