E.2.2 | Secondary objectives of the trial |
To verify if PET / CT with 68Ga-IL2 can be used to predict the prognosis of these patients and to select, more early and in a non-invasive way, those subjects candidates to receive invasive and targeted treatments. Correlate the uptake of 68Ga-IL2 with the different subpopulations of T-activated lymphocytes |
Verificare se la PET/TC con 68Ga-IL2 possa essere utilizzata per predire la prognosi di questi pazienti e per selezionare, più precocemente ed in modo non invasivo, quei soggetti candidati a ricevere trattamenti invasivi e mirati. Correlare l’uptake della 68Ga-IL2 con le differenti sottopopolazioni di linfociti T-attivati
