APOBEC3B High Expression in Gastroenteropancreatic Neuroendocrine Neoplasms and Association With Lymph Metastasis

Purpose:Apolipoprotein B mRNA editing enzyme catalytic polypeptide-like 3B (APOBEC3B) is known as a source of mutations in multiple cancers. Gastroenteropancreatic neuroendocrine neoplasms (GEP-NENs) are a group of heterogeneous tumors. However, the expression and significance of APOBEC3B in GEP-NEN
