[COVID-19 and melanoma: a single center retrospective cohort study from Hungary].

COVID-19 pandemic affected the diagnosis and management of many diseases, including the most vulnerable group of patients with cancer. In this retrospective survey we evaluated the course of disease of patients treated for melanoma, who got infected with COVID-19 virus between March 2020 and April 2021. 382 patients had been treated for advanced melanoma in our center in this time period. 24 of them had been infected with coronavirus. Six of them suffered in stage III melanoma, the remaining 18 patients had stage IV disease. 14, 5 and 4 of the infected patients had been administered with checkpoint inhibitor, targeted therapy and chemotherapy, respectively. Seven (29%) patients died in COVID-19 infection, in a median of 12 days. None of our patients who had been vaccinated at least one time, had severe symptoms. As a conclusion, the mortality of COVID-19 infection was significantly higher among our melanoma patients compared to the age-standardized mortality rate in Hungary.
