Methods: We studied 19 patients diagnosed with cancer in childhood or adolescence who underwent thyroidectomy and supplemental therapy with I-131. We also recruited a control group of healthy subjects with the same demographic parameters. All patients were subjected to a scintigraphy examination of the salivary glands, and were also asked to complete a questionnaire in order to assess their overall quality of life. In addition, a more specific questionnaire for patients with head and neck cancer was also given to all study participants. Results: The quantitative and qualitative analyses of the salivary glands showed functional deficits with greater involvement of the parotid gland for volume, concentration and excretion. The right submandibular gland showed significant changes for volume in the patient group. The questionnaires made it possible to observe significant differences between the patient and control groups for symptoms such as thick saliva, dry mouth and speech problems. Conclusion: In spite of being very effective and widely used, iodine radionuclide therapy is correlated with a lower quality of life in young people.展开更多
