Insights

Recent advances in parathyroid carcinoma (PC) management include improved diagnostics like circulating tumor cells and advanced imaging. Emerging targeted therapies offer new hope for advanced disease.

Area of Science:

  • Endocrinology and Oncology
  • Rare Cancers Research

Background:

  • Parathyroid carcinoma (PC) is a rare malignancy, accounting for 1% of primary hyperparathyroidism (PHPT) cases.
  • Effective management strategies for PC are crucial due to its aggressive nature.

Purpose of the Study:

  • To review recent advancements in the diagnosis and management of parathyroid carcinoma.
  • To highlight molecular insights, diagnostic tools, surgical techniques, and targeted therapies.

Main Methods:

  • A narrative review of manuscripts published between 2023 and 2024.
  • Literature search conducted in PubMed, EMBASE, and Cochrane Central Register of Controlled Trials (CENTRAL).

Main Results:

  • Diagnostic accuracy is improving with novel biochemical markers like circulating tumor cells (CTCs) and advanced imaging (18F-FDG PET/CT, 4D-CT).
  • Surgical resection remains the cornerstone for localized and metastatic PC.
  • Emerging targeted therapies including tyrosine kinase inhibitors (TKIs), temozolomide, and immune checkpoint inhibitors (ICIs) show potential for specific patient groups with advanced or unresectable disease.

Conclusions:

  • Continued research is needed to further improve outcomes for parathyroid carcinoma patients.
  • Management of advanced PC should be centralized in specialized centers of excellence for optimal care.
