Overview
If left untreated, patients with insulinoma may progress to develop seizures, coma and may be even death.Prognosis is generally excellent for benign insulinoma after the removal of the tumor. Recurrence rates are higher in those associated with MEN1 syndrome.
Natural History, Complications, and Prognosis
Natural History
- The symptoms of (disease name) usually develop in the first/ second/ third decade of life, and start with symptoms such as ___.
- The symptoms of (disease name) typically develop ___ years after exposure to ___.
- If left untreated, hypoglycemia progresses in frequency, although the tumor size remains small.[1]
Complications
- Common complications of insulinoma include those with hypoglycemia:
Prognosis
- 90% insulinomas are benign and they are generally cured after the removal of the tumor, so benign insulinoma is associated with the most favorable prognosis.[3]
- The prognosis varies with the malignant potential of the tumor; Grade 1 and 2 tumor have the most favorable prognosis.
