ZFP36 and gastric cancer: Statistical analysis showed that TTP expression was not significantly correlated with sex (P = 0.839), age (P = 0.168), differentiation status (P = 0.841), or distant metastasis (P = 0.066), whereas significant correlations were found between TTP expression and depth of invasion (P = 0.001), lymph node metastasis (P = 0.010), and the TNM stage (P < 0.001) of patients with GC (Table 2).
