Tumor mutation burden and PD-L1 expression in MM and CM. MM presented lower tumor mutation burden and PD-L1 expression compared to CM. a Number of mutations per sample was assessed by mutational spectrum analysis. Box plots showing the number of mutations per specimen in MM (n = 41) and CM (n = 48). b PD-L1 expression was analyzed for MM and CM by immunohistochemistry. Box plots showing the PD-L1 expression (H score) in MM (n = 21) and CM (n = 18) (**p < 0.01)
