Expression level of ACACB (HR: 3.88, 95% CI: 1.50-10.02), FABP3 (HR: 3.24, 95% CI: 1.31-8.04), PDK4 (HR: 3.22, 95% CI: 1.21-7.72), PPARG (HR: 2.71, 95% CI: 1.01-7.42), and PLIN5 (HR: 3.42, 95% CI: 1.01-11.68) was significantly associated with OS in OSCC after adjusted for TNM stage and lymph node metastasis (Figure 3(c)). This evidence concerns the gene PLIN5 and metastatic malignant neoplasm in the lymph nodes.
