Background: Appendiceal carcinoid tumors (ACTs) are rare, and little is known about the long-term prognosis for these tumors because no staging system exists. Therefore, we sought to investigate prognostic factors associated with ACTs and to create a predictive staging system to accurately estimate prognosis.Hypothesis: In patients with ACTs, TNM staging will accurately predict prognosis.
A staging system for GISTs that provides valuable prognostic information was developed. Further work to refine this system and validate it with other data sets should be undertaken. Mitotic index and standardized reporting may provide additional prognostic information and should be recorded for all tumors so that the most accurate staging system can be created.
Obese patients had a higher rate and greater severity of postoperative complications, with increased operative blood loss. However, obese patients did not demonstrate any significant difference in specific oncologic factors or survival. These data suggest an equivalent biologic effect of obesity on pancreatic cancer survival.
Surgical resection is associated with a lower chance of recurrence and a longer disease-free interval than RFA and should remain the treatment of choice in resectable HCM.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
