Accordant with aforementioned results, melanoma patients with PTPRT mutations harbored a markedly preferable ICI prognosis than those without such mutations in Kaplan–Meier analysis (Log‐rank test p = 0.019; Figure 7C) and multivariate Cox model (HR: 0.57, 95% CI: 0.36–0.90, p = 0.023; Figure 7D). The gene discussed is PTPRT; the disease is melanoma.
