Core Tip: Protein tyrosine phosphatase nonreceptor 2 (PTPN2) is a member of the protein tyrosine phosphatase family of signaling proteins. Numerous studies have examined the roles of this molecule in antitumor immunity and therapy because of its significant effects on a wide range of events, including the production and distribution of immune cells and numerous pathways that are important to the behavior and treatment of cancers. The role of PTPN2 in gastrointestinal (GI) cancers has been investigated in a limited number of studies, indicating that PTPN2 has heterogeneous effects on different tumors and even on the same type of GI cancer. Currently, this situation limits the recommendation of PTPN2 as a potential biomarker for predicting cancer prognosis and the efficacy of immunotherapy necessitates further studies in GI tumors.
