We next analysed all the genes that were mutated in our samples and correlated the mutated genes with the corresponding biological information, including tumour grade, degree of differentiation and invasiveness, proliferation index and extent of immune cell infiltrate (CD45+, CD3+ and CD68+ cells) (Fig. 2; Supplementary Figs. 2, 3 and 5a, d, Supplementary Data 1). Here, CD68 is linked to neoplasm.
