1182P Baseline neutrophil-lymphocyte ratio and its variations after adjuvant radiotherapy predict clinical survival outcomes in locally advanced Merkel cell carcinoma (MCC)

High baseline neutrophil-lymphocyte ratio (NLR) ≥ 3.5 was shown to be a negative prognostic factor in several solid cancers including MCC. The present study explores the prognostic and predictive role of basal NLR and its variations after adjuvant radiotherapy (RT) in stage II-III MCC patients (pts). We retrospectively identified 95 stage II-III MCC pts referred to our Institution from 2004 to 2019. All pts had Eastern Cooperative Oncology Group...
