Long-term survival outcomes using Kaplan–Meier’s analysis: a long-term survival outcomes in gastrointestinal MANEC, carcinoid and adenocarcinoma. The survival was better in gastrointestinal carcinoid (p < 0.001) and worsen in gastrointestinal adenocarcinoma (p = 0.0167) compared with gastrointestinal MANEC. b Long-term survival outcomes in localized, regional and distant gastrointestinal MANEC. Graph shows increasing survival from localized to distant (p < 0.001). The P values reported for survival analysis refers to comparison among all stage. c Long-term survival outcomes in treatment of gastrointestinal MANEC (p < 0.001). d Long-term survival outcomes in appendiceal and cecal MANEC (p < 0.001). e Long-term survival outcomes in gastrointestinal MANEC results of lymph node examination (p < 0.001). f Long-Term Survival Outcomes in tumor size of gastrointestinal MANEC (p < 0.001)
