Primary gastrointestinal lymphomas (PGIL) is a relatively rare tumor
subtype, accounting for 5%-20% of all extra nodal lymphomas, including
diffusion large B-cell lymphoma, Mucosa-associated lymphoid tissue lymphoma,
mantle cell lymphoma, Burkitt lymphoma, follicular lymphoma, intestinal T
cell lymphoma and other lymphomas. The incidence of PGIL is increasing day
by day. With the continuous advancement of imaging diagnosis technology, the
diagnosis and treatment of gastrointestinal lymphoma is gradually refined. This
article reviewed the common pathological types, diagnostic methods, common
clinical manifestations, treatment methods, survival prognosis and other factors
of each part of PGIL (stomach, small intestine, colorectal). Provide theoretical
support for clinicians in the diagnosis and treatment of PGIL.
