High KLRF1 expression was also significantly associated with improved RFS (HR = 0.53, p = 0.01), CSS (HR = 0.47, p = 0.02), and OS (HR = 0.54, p = 0.02) on multivariable analysis that included patient age, gender, pathologic stage, tumor MHC I, and tumor molecular subtype (Table 3). This evidence concerns the gene KLRF1 and neoplasm.
