In patients with metastatic melanoma, ipilimumab has been shown to improve long-term survival. This observational multicenter study reports clinical outcomes of 418 patients treated with second line ipilimumab from February 2013 to August 2014. Median overall survival (OS) was 6.43 months (95%CI: 5.45-7.42; n = 300), while median progression-free survival (PFS) was 3.7 months (95%CI: 3.23-4.17; n = 188). Demographic factors, such as sex or number of previous therapies did not affect OS. Survival was shorter in patients with ECOG > 0 (Eastern Cooperative Oncology Group, Performance Status) (p < 0.001), while a longer OS was found in patients who completed all four therapy cycles (p < 0.001). Adverse events of any grade were reported for 66% of patients (mainly cutaneous and gastrointestinal), but most were low grade and easily managed. Adverse events of grades 3-4 were observed in 13% of patients. This study confirmed the efficacy and safety of this treatment in real practice.
