Table 1. TNM classification of JI-NETs according to ENETS/UICC and AJCC.

T – Primary tumor
	ENETS/UICC	AJCC
	Primary tumor cannot be assessed	Primary tumor cannot be assessed
	No evidence of primary tumor	No evidence of primary tumor
	Tumor invades mucosa or submucosa and size ≤1 cm	Tumor invades mucosa or submucosa and size ≤1 cm
	Tumor invades muscolaris propria or size >1 cm	Tumor invades muscolaris propria or size >1 cm
	Tumor invades subserosa without penetration of overlying serosa	Tumor invades subserosa without penetration of overlying serosa
	Tumor invades peritoneum/other organs	Tumor invades peritoneum/other organs
TNM – tumor, node, metastasis; JI-NETs – jejunoileal neuroendocrine tumors; ENETS – European Neuroendocrine Tumor Society; UICC – International Union Against Cancer; AJCC, American Joint Committee on Cancer.
N – Regional lymph node metastasis
	ENETS/UICC	AJCC
	Regional lymph nodes cannot be assessed	Regional lymph nodes cannot be assessed
	No regional lymph node metastasis	No regional lymph node metastasis
	Regional lymph node metastasis	Regional lymph node metastasis less than 12 nodes
		Large mesenteric masses (>2 cm) and/or extensive nodal deposits (12 or greater), especially those that encase the superior mesenteric vessels
TNM – tumor, node, metastasis; JI-NETs – jejunoileal neuroendocrine tumors; ENETS – European Neuroendocrine Tumor Society; UICC – International Union Against Cancer; AJCC, American Joint Committee on Cancer.
M – Distant metastasis
	ENETS/UICC	AJCC
	Distant metastasis cannot be assessed	Distant metastasis cannot be assessed
	No distant metastasis	No distant metastasis
	Distant metastasis	Distant metastasis
		Metastasis to liver
		Metastasis in at least 1 extrahepatic site (eg, lung, ovary, nonregional lymph node, peritoneum, bone)
		Both hepatic and extrahepatic metastasis
TNM – tumor, node, metastasis; JI-NETs – jejunoileal neuroendocrine tumors; ENETS – European Neuroendocrine Tumor Society; UICC – International Union Against Cancer; AJCC, American Joint Committee on Cancer.
