Can a neuroendocrine tumor be cured?

What is the success rate for chemotherapy?

Five years after treatment, the rate of overall survival was 98.1% for those who had chemo and 98.0% for those who did not. Nine years after treatment, the rate of overall survival was 93.8% for those who had chemo and 93.9% for those who did not.

How can you tell if a tumor is shrinking?

Scans like X-rays and MRIs show if your tumor is smaller or if it’s gone after surgery and isn’t growing back. To qualify as remission, your tumor either doesn’t grow back or stays the same size for a month after you finish treatments. A complete remission means no signs of the disease show up on any tests.

Do neuroendocrine tumors have to be removed?

For some NETs, surgery is the only treatment you need. For a NET that has spread to other parts of the body, your surgeon might still do surgery to remove most of the tumour. This is called debulking. Debulking surgery can help to control your symptoms and help you feel better, but won’t get rid of the NET.

Can neuroendocrine tumors come back?

The chance that neuroendocrine cancer will come back (recur) is greatest within 5 years, so close follow-up is needed during this time.

How fast do neuroendocrine tumors grow?

They usually grow slowly over many years, but there are fast-growing forms. There are many types of neuroendocrine tumors, but most are classified as one of two main types: Carcinoid tumors – NETs that most commonly arise in the digestive tract, lungs, appendix or thymus.

The neuroendocrine mechanisms of chronic stress. Chronic stress produces stress hormones during the activation of the neuroendocrine system (hypothalamus-pituitary-adrenal axis) and the sympathetic nervous system, which can promote tumor development and regulate the tumor microenvironment.
