Neuroendocrine Tumours (NET) – hiding in plain sight – an awareness post from Ronny Allan
When I was diagnosed, I didn’t even feel ill. It was therefore a bit of a shock being told I had metastatic cancer, advanced enough to
Appendiceal neuroendocrine tumours (aNET) account for 50%–77% of all appendiceal neoplasms and are mostly identified incidentally following appendicectomy for acute appendicitis or after a laparotomy performed for unrelated reasons. In the great majority, aNET are low grade (>80% grade 1 (G1)) and very rarely, if ever, are associated with a secretory syndrome.
This post is part of my ENETS Guideline series and supplements my Spotlight series article which can be found by clicking here.
| Q1 – What is the current incidence of aNET (G1-3)? |
| Q2 – Which are the pathological parameters that need to be provided for further decision-making? |
| Q3 – How common are LN and distant metastases and carcinoid syndrome (CS) in appendiceal NET? Is LN status an acceptable surrogate of OS? |
| Q4 – Is there any indication for biochemical and/or imaging modalities to be utilised for tumour staging following appendicectomy? |
| Q5 – Is there any indication for biochemical and/or imaging modalities to be utilised for tumour staging following appendicectomy? |
| Q6 – When completion oncological surgery is recommended, is RHC always required or could ileocaecal resection be sufficient, and what is the impact of these |
| Q7 – Is there any need for adjuvant therapy in patients with aNET without distant metastases? |
| Q8 – How should advanced disease be managed? |
| Q9 – What is the recommended follow-up protocol after RHC in patients with or without LN+ ? How is follow-up in aNET justified? |
