CHECK-POINTS IMMUNITARI
(Ipilimumab – Nivolumab/Pembrolizumab – anti CD137 –

FARMACI AD ATTIVITA’
TARGETED “GENETIC-DRIVEN”
(BRAFi – MEKi)
Modulation of T-cell function
T-cell activation occurs through the
interaction with an APC
Additional signals occur through
interactions of costimulatory
molecules
T-cell functions are tightly regulated
through various costimulatory and
inhibitory molecules
Modulation of T-cell activation by
targeting these regulatory molecules
is an area of active research
CTLA-4 were developed as anticancer therapies under the
theory that through blockade of the CTLA-4-mediated
inhibitory signal, the activity of T-cells may be activated
against tumor antigens and their activity harnessed for
treatment of cancer.3,13

responses in a limited number of patients, to the point
where
the question of “cure”
in these cases must be entertained.”

Melanoma Immunotherapy:
Future Directions
 Targeted monoclonal antibody therapy
– Anti–CTLA-4 therapy
– Dose, schedule, toxicity
– Novel antibodies: anti–PD-1, anti-CD137, anti-CD40
 Adoptive-cell therapy
– Combined use of CD4+ and CD8+ T cells
– Combination therapy with anti–CTLA-4/anti–PD-1 antibodies
– Stimulating transferred lymphocytes with new/better combinations
of agents
 Combinatorial immunotherapy with targeted therapy,
antiangiogenic agents, and chemotherapy
NUOVI SCENARI
Per il Chirurgo: Elettrochemioterapia;
Metastasectomia di melanoma oligometastatico
(NCCN 2014).
Per l’Oncologo: trattamento neoadiuvante,
adiuvante e delle sequele a lungo termine.
Per lo Psicologo: trattamento dell’ansia
cronica.
CONCLUSIONI
• Il Paziente con melanoma avanzato inizia ad avere
miglior qualità di vita e spravvivenza prolungata
• Risposte obiettive significative, miglior controllo
del dolore, prolungamento della “dormant phase”
• L’oncologo inizia a focalizzare l’attenzione su
problematiche “croniche”
• Format psico-assistenziale per Pazienti con
particolare autocoscienza di malattia
Grazie per l’attenzione
