Answer

Answer

NCCN recommendations for appendix NETs are as follows [7] :

  • Tumors ≤2 cm confined to the appendix: Appendectomy

  • Tumors ≤2 cm with lymphovascular or mesoappendiceal invasion or atypical histologic features: More aggressive treatment can be considered

  • Incomplete resection or tumors >2 cm: Staging with abdominal/pelvic CT or MRI; if no distant disease, reexploration with a right hemicolectomy
