FN1 and metastatic malignant neoplasm in the lymph nodes: Stromal FN expression (OS: HR, 2.022; 95% CI, 1.169–3.498; P = 0.012; PFS: HR, 2.498; 95% CI, 1.444–4.319; P = 0.001) and lymph node metastasis (OS: HR, 2.158; 95% CI, 1.207–3.857; P = 0.009; PFS: HR, 1.783 95% CI, 1.031–3.082; P = 0.039) were independent prognostic factors for OS and PFS in patients with ESCC.
