Abstract

Redifferentiation therapy with Dabrafenib (a BRAF inhibitor) and Trametinib (a MEK inhibitor) restores radioiodine avidity of radioiodine-refractory papillary thyroid carcinoma (PTC). A 50-year-old man was diagnosed with radioiodine-refractory PTC pulmonary metastasis post prior total thyroidectomy and radioiodine ablation. The patient was treated with Dabrafenib and Trametinib, followed by second radioiodine ablation with I-131 sodium iodine. Diffuse increased radioiodine uptake by pulmonary metastasis was visualized on post ablation whole body scan. Response to second radioiodine ablation was demonstrated by decrease in size of pulmonary nodules seen on chest CT, along with decrease of thyroglobulin level.

Dabrafenib和Trametinib治疗甲状腺乳头状癌肺转移增强放射性碘摄取

使用达拉非尼（一种BRAF抑制剂）和曲美替尼（一种MEK抑制剂）进行再分化治疗可恢复放射性碘难治性甲状腺乳头状癌（PTC）的放射性碘嗜性。一名 50 岁的男性在接受甲状腺全切除术和放射性碘消融术后被诊断为放射性碘难治性 PTC 肺转移。患者接受了达拉非尼（Dabrafenib）和曲美替尼（Trametinib）治疗，随后使用I-131碘化钠进行了第二次放射性碘消融。消融术后全身扫描显示肺转移灶弥漫性放射性碘摄取增加。胸部CT显示肺结节缩小，甲状腺球蛋白水平下降，这表明患者对第二次放射性碘消融有反应。

期刊介绍： Nuclear Medicine and Molecular Imaging (Nucl Med Mol Imaging) is an official journal of the Korean Society of Nuclear Medicine, which bimonthly publishes papers on February, April, June, August, October, and December about nuclear medicine and related sciences such as radiochemistry, radiopharmacy, dosimetry and pharmacokinetics / pharmacodynamics of radiopharmaceuticals, nuclear and molecular imaging analysis, nuclear and molecular imaging instrumentation, radiation biology and radionuclide therapy. The journal specially welcomes works of artificial intelligence applied to nuclear medicine. The journal will also welcome original works relating to molecular imaging research such as the development of molecular imaging probes, reporter imaging assays, imaging cell trafficking, imaging endo(exo)genous gene expression, and imaging signal transduction. Nucl Med Mol Imaging publishes the following types of papers: original articles, reviews, case reports, editorials, interesting images, and letters to the editor. The Korean Society of Nuclear Medicine (KSNM) KSNM is a scientific and professional organization founded in 1961 and a member of the Korean Academy of Medical Sciences of the Korean Medical Association which was established by The Medical Services Law. The aims of KSNM are the promotion of nuclear medicine and cooperation of each member. The business of KSNM includes holding academic meetings and symposia, the publication of journals and books, planning and research of promoting science and health, and training and qualification of nuclear medicine specialists.
