Carcinoid Appendix – Symptoms and Treatment of Carcinoid Appendix

Carcinoid tumors are the most commonly seen tumors of all the appendix tumors. These are neuro-endocrine tumors which means they release and create hormones into the blood. This usually happens with metastatic diseases where they spread to other parts of the body from the appendix. Carcinoids are very small yellow colored tumors that are found in the appendix.
This tumour is located in that part where the appendix attaches the colon that is closer to the tip of the appendix. They are mostly seen during other pelvic or abdominal surgeries like hysterectomy, gall bladder removal, etc. These tumors are slow growing, slow, small and very rarely spread to other area.


Carcinoids do not show any symptoms but symptoms may be seen with metastasis when it spreads to other organs especially to the liver.


The treatment for carcinoid appendix are :

  • Tumors that are less than 1 cm in their diameter may be treated by the surgical removal of the appendix that is appendectomy. This surgery is 100% curative and over 95% of carcinoid tumors are usually less than 2cm in size.
  • Tumors that are up to 1.5 to 2 cm are treated with appendectomy or sometimes with hemicolectomy where the half part of the right side of the colon is removed.
  • If the carcinoids are greater than 2 cm then there are chances of metastasize. The surgical intervention for these larger carcinoids are appendectomy and hemicolectomy. A surgeon may also remove the local lymph nodes to prevent further spread.
  • If these carcinoids spread that is metastasize then they spread mostly to the lymph nodes or liver. Chemotherapy is not very successful but 30% of the people are found to response to chemotherapy. If the tumors spread then they can be removed surgically.

Appendix carcinoids are seen commonly among women in a ratio of 2:1 or 3:1. The survival rate is over 5 years as reported by a medical research.
