Vandetanib Tumor Shrinkage in Metastatic Medullary Thyroid Cancer Allowing Surgical Resection of the Primary Site: A Case Report.

Vandetanib has been shown to improve progression-free survival in adults with advanced medullary thyroid cancer. This article describes a pediatric patient with metastatic medullary thyroid cancer secondary to sporadic multiple endocrine neoplasia 2B, treated with vandetanib. At presentation, he had an inoperable primary tumor, with carotid encasement, and pulmonary metastases.

Use of Vandetanib in Metastatic Medullary Carcinoma of Thyroid in a Pediatric Patient With Multiple Endocrine Neoplasia 2B.

We describe a child with advanced, metastatic, inoperable medullary carcinoma of thyroid associated with multiple endocrine neoplasia 2B and rearranged during transfection mutation with a positive response to vandetanib treatment. He responded well with a fall in calcitonin levels and a reduction in size of the thyroid malignancy, lymph nodes, and pulmonary metastases. He has been on vandetanib for 4 years with good clinical and biochemical response.

Standardising reporting of cervical lymphadenopathy in paediatric neck ultrasound: a pilot study using an evidence-based reporting protocol.

Objectives: Cervical lymphadenopathy is common in children and can arise from a wide range of aetiologies. Ultrasound can be a useful imaging tool for initial investigation but is known to be operator dependent. We aimed to compare the content of ultrasound reporting in this clinical scenario before and after the introduction of an evidence-based reporting protocol.
