Long-term survival of stage IV melanoma patients: evaluation on 640 melanoma patients entering stage IV between 2014 and 2017.

This dataset comprises the largest available cohort of long-term surviving stage IV melanoma patients. Since 90% of patients in our cohort are still alive today, we expect an increasing number of long-term survivors in the future. Our data indicate the need for specific follow-up programs addressing the needs of long-term survivors.
