The great debate at "Melanoma Bridge 2018", Naples, December 1st, 2018.

The great debate session at the 2018 Melanoma Bridge congress (November 29-December 1, Naples, Italy) featured counterpoint views from experts on three topical issues in melanoma. These were whether overall survival should still be the main endpoint for clinical trials in melanoma, whether anti-cytotoxic T-lymphocyte-associated antigen (CTLA)-4 is still the optimal choice of drug to use in combination with an anti-programmed death (PD)/PD-ligand (L)-1 agent, and the place of adjuvant versus neoadjuvant therapy in patients with melanoma. These three important debates are summarised in this report.
