Preventing thyroid problems in children undergoing radiation therapy for cancer

Protection From Iatrogenic Hypothyroidism Patients With MBL and Pediatric Patients With HL and Non-HL Needing Radiotherapy on Thyroid Site

Phase 3 Interventional Fondazione IRCCS Istituto Nazionale dei Tumori, Milano · NCT05316922

This study is testing if giving a thyroid medication to children with cancer who are getting radiation therapy can help prevent thyroid problems later on.

What this trial studies

This clinical trial aims to reduce the incidence of hypothyroidism in pediatric cancer patients receiving radiation therapy by suppressing thyroid-stimulating hormone (TSH) levels. Participants will be randomly assigned to either a TSH suppression group, receiving L-thyroxine, or a control group without TSH suppression. The study will involve baseline thyroid assessments and careful monitoring of hormone levels throughout the treatment process. The goal is to maintain TSH levels below a specific threshold during radiation therapy to prevent long-term thyroid dysfunction.

Who should consider this trial

Good fit: Ideal candidates are children diagnosed with medulloblastoma or Hodgkin/non-Hodgkin lymphoma who are about to undergo radiation therapy.

Not a fit: Patients who have already undergone radiation therapy or those who have a history of primary or secondary hypothyroidism will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly decrease the risk of hypothyroidism in children treated for cancer, improving their long-term health outcomes.

How similar studies have performed: While the specific approach of TSH suppression during radiation therapy is novel, similar studies have indicated that hormone management can positively influence outcomes in patients undergoing cancer treatment.
