AI Article Synopsis

  • Parathyroid carcinoma is a rare cancer with surgery as the main treatment, but many patients face recurrence or metastasis, and there's no standard care for advanced cases.
  • A 41-year-old patient with inoperable parathyroid carcinoma was treated effectively with a combination of radiofrequency ablation (RFA), external beam radiation therapy (EBRT), and sorafenib.
  • After 11 months of sorafenib, his calcium levels normalized, and the disease remained stable for 18 months after stopping the medication, suggesting this multimodal approach could be a viable option for similar cases.

Article Abstract

Parathyroid carcinoma is a rare endocrine malignancy for which the primary treatment is surgery; however, 50% of the patients develop local recurrence or distant metastases. No consensus exists on the standard treatment for metastatic parathyroid cancer. Here we report a case of a 41-year-old male with inoperable locally advanced parathyroid carcinoma who was successfully treated with multimodal therapy including radiofrequency ablation (RFA), external beam radiation therapy (EBRT) to the neck, and sorafenib. Eleven months after initiating sorafenib, serum calcium levels were normal, and both the intact PTH level and the size of metastatic lesion remained stable; thus, we decided to discontinue sorafenib. After discontinuation, the disease remained stable for 18 months and continues to be so. Hence, clinicians can consider multimodal treatment with RFA, EBRT, and sorafenib as a treatment option for locally advanced parathyroid carcinoma.

Background: Preoperative localization of hyperfunctioning parathyroid glands in primary hyperparathyroidism is essential for successful parathyroid surgery, particularly in patients with previous negative imaging or reoperations.

Methods: A multicenter registry study was performed in 776 patients with primary hyperparathyroidism from 53 hospitals in Germany and Austria who underwent parathyroid surgery after preoperative F-choline or C-methionine positron emission tomography/computed tomography (PET/CT).

Results: In 683 of 776 patients (88%) (78% female, aged 15-86 years), primary hyperparathyroidism was caused by a single-gland parathyroid adenoma.

Denosumab, an anti-RANKL antibody, induces bone metabolism to a low-turnover bone status by arresting osteoclast activity. Frequent adverse events include infusion reactions, fever and hypocalcaemia but not hypophosphataemia. We report a case of severe hypophosphataemia associated with secondary hyperparathyroidism following denosumab administration in a young boy with recurrent osteosarcoma who was successfully treated with evocalcet.

Purpose: Parathyroid carcinoma (PC) is an extremely rare disease, typically presenting with marked elevations of serum calcium concentrations and associated with significantly increased parathyroid hormone (PTH) levels. Although it progresses slowly, approximately25% of PC patients have lung metastases. In the present study, we aimed to evaluate the role of technetium-99m methoxy isobutyl isonitrile (Tc-99m-MIBI; sestamibi) SPECT/CT scintigraphy in the preoperative localization of parathyroid adenomas, incidental metastases findings of PC, and ectopic parathyroid tissue.

Establishing genotype-phenotype correlations in disorders of hereditary endocrine neoplasia is important for clinical screening, genetic counseling, prognostication, surveillance, and surgical strategy, and may also provide clues about disease pathogenesis. Important genotype-phenotype correlations are recognized, for example, in pheochromocytoma/paraganglioma and multiple endocrine neoplasia type 2A. The presence of such correlations has been less clear in other familial endocrine disorders associated with primary hyperparathyroidism including multiple endocrine neoplasia type 1 (MEN1), and the hyperparathyroidism-jaw tumor syndrome (HPT-JT).

Parathyroid carcinoma (PC) is a rare endocrine malignancy that poses significant diagnostic challenges due to its resemblance to benign conditions. This case series describes the clinical presentation, diagnosis, management, and short-term outcomes of four male patients (aged 54, 65, 73, and 74 years) with primary hyperparathyroidism and hypercalcemia. The preoperative diagnosis of PC remains challenging; suspicion should arise in cases of severe hypercalcemia, elevated parathyroid hormone levels, and the presence of a mass on imaging or during surgery.
