Immunotherapy and Thyroid Dysfunction: Relevance to Nuclear Medicine.
CLINICAL NUCLEAR MEDICINE(2020)
摘要
We report a case of a 66-year-old woman with small cell lung cancer (stage IIB, T2N1M0), who received immunotherapy with nivolumab monthly for 2 months and then presented with thyrotoxic symptoms associated with suppressed thyroid-stimulating hormone levels and elevated free thyroid hormone levels, although previous thyrotropin performed 1 month ago was normal. Thyroid uptake and scan demonstrated diffusely decreased uptake in both thyroid lobes. The 4-hour percentage uptake was 0.7%, and the 24-hour percentage uptake was 0.3%. This was followed by development of hypothyroidism within few weeks. Findings suggested drug-induced thyroiditis secondary to nivolumab therapy.
