European Neuroendocrine Tumor Society ( ENETS ) 2023 guidance paper for appendiceal neuroendocrine tumours ( aNET )
Open accessAbstract
The aim of the present guidance paper is to update the previous ENETS guidelines on well differentiated appendiceal neuroendocrine tumours (NET), providing practical guidance for the diagnosis and management of appendiceal NET (aNET); poorly differentiated neoplasms are dealt with in a separate guidance paper. This paper is structured on a question‐answer format in order to also address controversial issues and areas where uncertainty regarding the management and follow‐up of aNET exists. All recommendations are offered on the basis of the best available evidence, along with the authors' experiences in managing these neoplasms. Each recommendation for treatment will provide a level of evidence and grade of recommendation as per the GRADE system (adapted in Infectious Disease Society of United States Public Health Service grading system).

Neuroendocrine tumors can present in varied morphologic forms and are frequently not detectable through intraoperative visualization alone.
“Neuroendocrine tumors can present in varied morphologic forms and are frequently not detectable through intraoperative visualization alone, emphasizing the critical role of histopathological assessment.”
From Selective Appendectomy in Patients Undergoing Minimally Invasive Surgery for Endometriosis: A Retrospective Cohort Study (2025) · cites this paper as [30]
Section 2 describes distinct histological types of appendiceal neuroendocrine tumours, and Section 3 says they may not be visible to the surgeon; Section 3.2 adds that most are not detected on macroscopic examination. These passages support the point for appendiceal tumours, but do not establish it for neuroendocrine tumours generally. (LLM, conf=0.86)
Experimental — accuracy not yet measuredPrevious studies have reported that even normal-appearing appendices may harbor intraluminal pathology, which can be missed without tissue analysis.
“Previous studies have reported that even normal-appearing appendices may harbor intraluminal pathology, which can be easily missed without tissue analysis, potentially allowing disease progression if left in situ [30,31].”
From Selective Appendectomy in Patients Undergoing Minimally Invasive Surgery for Endometriosis: A Retrospective Cohort Study (2025) · cites this paper as [30]
Section 3 (page unavailable) says small appendiceal neuroendocrine tumours may be invisible to the surgeon and even to the pathologist on macroscopic examination, and recommends sectioning the tissue for examination. This supports the risk of missing pathology by appearance alone, but the paper does not specify that the pathology is intraluminal or address appendiceal pathology beyond these tumours.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
