With respect to patient age at diagnosis, LUAD patients who were diagnosed >65 years old showed a shorter RFS when their tumor expressed a high level of CSF3 (HR = 1.666, 95% CI = 1.09–2.547, and p = 0.0184 for the high vs. low CSF3 expression >65 subgroup; Fig. 3B). This evidence concerns the gene CSF3 and neoplasm.
