Results: In the analyzed period, a total of seven ICI were authorized in Italy for 20 cancer types. The estimated number of ICI-eligible patients in 2020 was 48,400, 14.3% of those tumors (including skin epitheliomas) that may fit AIFAindications, and 10.5% of all the incident malignant tumors, including skin epitheliomas. The number of patients who may benefit from ICI therapy was 24,052, 49.7% of the ICI-eligible ones, or 5.2% of the overall estimated incident cancers in 2020.  \nConclusions: In conclusion, although the number of ICI-eligible patients is a relatively small proportion of the yearly burden of cancers, about half of them may respond to ICI-treatment.  \nKeywords  \nburden, cancer, estimate, immune checkpoint inhibitors, therapy  \nDate received: 18 September 2023; revised: 11 December 2023; accepted: 11 January 2024  \nIntroduction  \nThe immune checkpoint inhibitors (ICI) are immunotherapy drugs acting on the Programmed Cell Death Protein 1 (PD-1) and Cytotoxic T-Lymphocyte Antigen (CTLA) pathways repressing negative immune regulation and reactivating T-cell functions. Therefore, they allow more effective cancer cell elimination.1 The use of these drugs has improved outcomes for patients affected by several advanced solid tumors.2 In Italy, seven ICI have been approved by the Italian Medicines Agency (AIFA) until August 2022: ipilimumab (YERVOY),3 nivolumab (OPDIVO),4 pembrolizumab (KEYTRUDA),5 atezolizumab (TECENTRIQ),6  \navelumab (BAVENCIO),7 durvalumab (IMFINZI),8 and cemiplimab (LIBTAYO) .9 Overall, these drugs were approved for the following indications: head and  \n1 Emilia-Romagna Cancer Registry, Romagna Unit, IRCCS Istituto Romagnolo per lo Studio dei Tumori (IRST) Dino Amadori, Meldola, Forlì, Italy  \n2Local Health Authority, Cancer Prevention Unit, Forlì, Italy  \nCorresponding author:  \nAlessandra Ravaioli, IRCCS Istituto Romagnolo per lo Studio dei Tumori Dino Amadori, Via Maroncelli 40/42, Meldola, 47014, Italy.
