Since high expression of RAB27A is potentially associated with lymph node metastasis in OSCC, we next analyzed the Tumor Node Metastasis (TNM) stages of the patients and found that patients with lower expression levels of RAB27A tended to be in the earlier stage of tumor progression (Figure 2A) and had fewer cases of metastasis to lymph nodes (Figure 2B). The gene discussed is RAB27A; the disease is metastatic malignant neoplasm in the lymph nodes.
