Prophylactic thyroidectomy in children with RET gene mutations is crucial for early detection and prevention of medullary thyroid carcinoma. Early surgical intervention in experienced centers significantly reduces complications and ensures favorable outcomes.
Area of Science:
- Endocrinology
- Genetics
- Pediatric Surgery
Background:
- RET proto-oncogene mutations are associated with an increased risk of medullary thyroid carcinoma (MTC).
- Prophylactic thyroidectomy is recommended for individuals with identified RET mutations to prevent MTC development.
Purpose of the Study:
- To analyze outcomes of prophylactic thyroidectomy in pediatric patients with RET gene mutations.
- To evaluate the efficacy and safety of early surgical intervention for MTC prevention.
Main Methods:
- Retrospective review of 25 pediatric patients undergoing prophylactic thyroidectomy for RET mutations (2000-2016).
- Analysis included epidemiological data, surgical techniques, histological findings, and patient follow-up.
Main Results:
- 16 out of 25 patients (64%) had MTC or precursor lesions at surgery.
- All patients underwent total thyroidectomy without immediate complications.
- Follow-up revealed normal biochemical markers in most patients, indicating successful intervention.
Conclusions:
- RET gene analysis identifies pediatric patients requiring prophylactic thyroidectomy.
- Early thyroidectomy in specialized centers is essential for managing MTC risk in these patients.

When the function of certain critical genes, especially those involved in cell cycle regulation and cell growth signaling cascades, gets disrupted, it upsets the cell cycle progression. Such cells with unchecked cell cycles start proliferating uncontrollably and eventually develop into tumors.
