Poor symptom control remains an important cause of distress. The low number of expressed needs may reflect patients' unwillingness to appear ungrateful, but the variability of information needs emphasizes the importance of an individual approach to patients with an apparently homogenous disease
A 61-year-old woman noticed a right neck lump in October 2001. Fine needle aspiration showed follicular neoplasm, adenoma versus carcinoma. The ultrasound scan showed a solid mass of maximum dimension of 3.7 cm. She had a right thyroid lobectomy and isthmectomy in January 2002 (first surgery). The tissue specimen showed a 4.5 cm Hurthle cell carcinoma (HCC) with vascular invasion. There were no capsular invasion, extra-thyroidal extension, or margin involvement. A completion left lobectomy (second surgery) was performed two weeks later. Therefore the pathological stage is II (T3N0M0). She received adjuvant radioactive iodine ablation for residual thyroid tissue. By 2003, she developed local recurrence, which was resected (third surgery), followed by adjuvant external beam radiotherapy. Unfortunately, she developed further recurrence in the left main bronchus, as identified by Indium-111 Octreotide (Curium, Missouri, USA) and positron emission tomography-computed tomography PET-CT imaging in 2006. She underwent a left pneumonectomy (fourth surgery) in July 2006. In November 2007 she was found to have mediastinal recurrence which was treated with high-dose external beam radiotherapy. She initially responded but developed more local recurrence and a lung metastasis by 2011. She was treated with brivanib with ixabepilone, under a phase I clinical trial with mixed response. Her treatment was discontinued secondary to toxicity and she succumbed to her disease in 2012. This case report illustrates the natural history and clinical decision making for patients diagnosed with HCC of the thyroid. Specifically, we highlight the clinical issues surrounding the histopathological diagnosis, extent of surgical resection, radioiodine diagnostic imaging/ablative treatment, as well as external beam radiotherapy.
Abstract:The clinical behaviour of Hurthle cell carcinoma (HCC) of the thyroid is variable and there are many controversies in the literature. Here, we summarize an up-to-date review of the literature on genetics, diagnosis (ultrasound scan, fine needle aspiration, frozen section, etc.), and management. At presentation, treatment decision should be made by a multidisciplinary board. Recurrent HCCs are seldom curable despite salvage treatments, which include radioactive iodine ablation, radiofrequency ablation, ethanol ablation, external radiotherapy, and systemic therapy. Further research is needed to develop more efficacious systemic treatments. Currently, lenvatinib, sunitinib, and sorafenib are available. The completed and ongoing clinical trials for HCC are summarized.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
