Table 2 Lugano staging of gastrointestinal tract lymphoma[60]
Stage

ITumor confined to GI tract
Primary site or multiple, non-contiguous lesions
IITumor extends into the abdomen from primary GI site
Nodal involvement
II1Local: Paragastric in cases of gastric lymphoma and para-intestinal for intestinal lymphoma
II2Distant: Mesenteric in case of an intestinal primary lymphoma; otherwise paraaortic, paracaval, pelvic, or inguinal
IIEPenetration of serosa involving adjacent organs or tissues: Enumerate sites of involvement, e.g., IIE (pancreas), IIE (large intestine), IIE (post-intestinal wall)
Where there is nodal involvement and penetration involving adjacent organs, the stage is denoted using a subscript (1 or 2) and E, e.g., II1E (pancreas)
IVDisseminated extra-nodal involvement or a GI tract lesion with supradiaphragmatic nodal involvement
