About half of metastatic melanoma patients treated with immune checkpoint inhibitors survive cancer-free for 10+ years, per a 10-year follow-up study from Weill Cornell Medicine and Dana-Farber Cancer Institute. The CheckMate 067 trial, involving 945 patients, showed nivolumab and ipilimumab combination significantly improved outcomes, with no new safety concerns. Median survival increased from 6.5 months to over 6 years, and patients free from cancer progression at 3 years likely remain disease-free at 10 years.
