We found these parameters predicting poor prognosis as we reported before by Multivariate Cox regression study [5]: tumour status (hazard ratio [HR], 1.77; 95% confidence interval [CI], 0.73–4.29; P = 0.204), stage (HR, 2.08; 95% CI, 1.15–3.77; P = 0.015), lymph node metastasis (HR, 1.70; 95% CI, 0.84–3.42; P = 0.139), high FGF9 expression (HR, 2.95; 95% CI, 1.97–4.41; P < 0.001) and tumour size (HR, 2.13; 95% CI, 1.30–3.47; P = 0.003)(Table 4). The gene discussed is FGF9; the disease is metastatic malignant neoplasm in the lymph nodes.
