Characterization of somatic mutations and tumor mutation burden in NKTCL. A The per-sample numbers of different categories of non-synonymous somatic mutations in primary (left) and relapsed/refractory (right) NKTCL. B Per-sample distribution of different categories of non-synonymous mutations in patients with primary (left) and relapsed/refractory (right) NKTCL. The dashed line denotes the median value. C The tumor mutation burden (TMB) profiles of primary (left) and relapsed/refractory (right) patients. The dashed line denotes the median value. D The comparison of TMB levels between the primary and the relapsed/refractory group. Brunner–Munzel test was applied for assessing the statistical significance. E The comparison of MSI score between the primary and the relapsed/refractory group. Brunner–Munzel test was applied for assessing the statistical significance
