Survival by disease stage in patients with well differentiated neuroendocrine tumors (SEER data, 1988–2004) [Yao et al. 2008a].

Stage	Median survival (months)	5-year survival	10-year survival
Localized*	Not reached	84%	70%
Regional$	151	72%	56%
Distant§	17	27%	15%

^*Localized: invasive neoplasm confined entirely to the organ of origin.

^$Regional: invasive neoplasm that extended beyond the limits of the organ of origin directly into surrounding organs/ tissues, involved regional lymph nodes, or fulfilled both aforementioned criteria.

^§Distant: neoplasm spread to parts of the body remote from the primary tumor.
