URGCP and non-small cell lung carcinoma: As shown in Table 1, URGCP expression strongly correlated with the clinical staging (P < 0.001), N classification (P =0.014), distant metastasis (P = 0.001) and pathological differentiation (P = 0.021) of patients with NSCLC, whereas this expression was not associated with age (P = 0.022), gender (P = 0.337), histological classification (P = 0.777), T classification (P = 0.664), and receiving therapy (P = 0.637).
