Popis: Abstract The treatment of patients with advanced melanoma has undergone a dramatic change over the past decade. Apart from refining the radiotherapy techniques, the repertoire of systemic treatments expanded from largely futile cytotoxic chemotherapy to substantially more effective MAP kinase and immune checkpoint inhibitors (Immunotargets Ther, 7, 2018)1. We report a case which exemplifies the improved efficacy as well as increased complexity of therapeutic decision‐making. A 71‐year‐old man presented with neglected fungating and bleeding malignant melanoma, which resulted in severe anaemia with consequent cardiac dysfunction. There was limited distant spread. Patient was treated with combined radiotherapy and immunotherapy: 55 Gray in 20 fractions over four weeks using 3D‐conformal technique followed by an anti‐PD1 antibody (pembrolizumab, Keytruda® Merck/MSD, Kenilworth N.J.; 2 mg/kg 3‐weekly). A surgical approach to provide haemostasis and cosmesis was considered, but would be associated with significant morbidity, prolonged recovery and functional impairment and would not have altered patient survival. The sequential radioimmunotherapy resulted in a complete response. Radiotherapy was completed with only mild skin toxicity. Immunotherapy was complicated by diarrhoea, which necessitated withdrawal of the medication but was controlled with steroids. The non‐operative treatment resulted in excellent oncological, functional and cosmetic outcome, with acceptable toxicity. Due to increasing complexity of melanoma therapy, a multidisciplinary approach is of paramount importance.
