More than that, after excluding the influence of other parameters, higher HOTAIR expression, higher miR‐17‐5p expression, poor differentiation, advanced AJCC stage (III + IV) and presence of lymph node metastasis appeared as predictors for gastric cancer patients’ poor prognosis (P < 0.05) (Table 3) (Figure 1C,D). The gene discussed is HOTAIR; the disease is metastatic malignant neoplasm in the lymph nodes.
