1 GEP NET: algoritmo terapeutico Dottor Nicola Fazio

2 Basi per il trattamento Caratteristiche del paziente Caratteristiche del tumore P.S., sindrome, comorbidità Differenziazione, Ki-67 Imaging morfologico Imaging funzionale AME statement

3 GEP NENs: treatments NET NEC TUMORI G1-G2 CARCINOMI G3 Ki67 (NET) (70-80%) < 20% Ki67 (NEC) (20-30%) > 20% Molecular targeted agents SSA Chemotherapy (alkylating, fluoropyrimidines) PRRT Locoregional therapies Clinical trials Chemotherapy (platinumbased)

4 NEN: guidelines NEN guidelines

5 GEP NEN Localmente avanzata Metasta?ca resecabile non resecabile solo epa?ca extraepa?ca CHIRURGIA CHIRURGIA CHIRURGIA +/- trakamen? locoregionali

6 Different liver tumor load Strategia medica sequenziale: SSA! EVE! TMZ! clinical trials Strategia citoriduttiva per chirurgia resettiva : chemio o PRRT +/- TAE

7 Mai resecabile Trapiantabile
