APOC1 and esophageal squamous cell carcinoma: The results showed that APOC1 mRNA expression had no significant effect on all tumors including EAC (p = 0.052) (Figure 3A) and EAC alone (p = 0.09) (Figure 3B), while patients with ESCC who overexpressed APOC1 mRNA in their tissues had a worse survival prognosis (p = 0.043) (Figure 3C).
