Lymphocyte-to-monocyte ratio is associated with survival in pembrolizumab-treated metastatic melanoma patients

The peripheral blood lymphocyte-to-monocyte ratio (LMR) has been associated with prognosis in many malignancies including metastatic melanoma. However, it has not been studied in patients treated with immune checkpoint inhibitors. In this study, we analyzed the baseline LMR with progression-free sur
