Background: Parathyroid carcinoma (PC) is a rare but often lethal malignancy for which staging system, prognostic indicators, and treatment guidelines are still not established. We aimed to explore the prognostic parameters and construct a nomogram for cancer-specific survival (CSS) of PC.
Methods: A retrospective analysis of 604 PC patients in the SEER database from 2001 through 2018 was performed. All the cases were randomly assigned to the training cohort ( = 424) or the validation cohort ( = 180) at a ratio of 7:3. The Kaplan-Meier method and Cox regression model were applied to estimate the CSS and risk factors, and a nomogram was constructed. The predictive accuracy and discriminative ability of the nomogram in CSS were assessed by concordance index (C-index), the area under the curve (AUC) of receiver operating characteristics (ROC), and the calibration curve.
Results: Age at diagnosis > 70 years [hazard ratio (HR): 3.55, 95% CI: 1.07-11.78, = 0.039] and tumor size > 35 mm (HR 4.22, 95% CI: 1.67-10.68, = 0.002) were associated with worse CSS. Compared with distant metastasis, localized (HR 0.17, 95% CI: 0.06-0.47, = 0.001) and regional lesions (HR 0.22, 95% CI: 0.07-0.66, = 0.007) showed an improved CSS rate. Parathyroidectomy was the recommended treatment ( = 0.02). The C-index of the nomogram was 0.826, and the AUC for 5-, 10-, and 15-year CSS was 83.7%, 79.7%, and 80.7%, respectively. The calibration curve presented good agreement between prediction by nomogram and actual observation.
Conclusion: Age at diagnosis > 70 years, tumor size > 35 mm, and distant metastasis were independent risk factors for PC-specific mortality. Parathyroidectomy was currently the most recommended treatment for PC. This nomogram provided individualized assessment and reliable prognostic prediction for patients with PC.

Hyperparathyroidism-jaw tumor syndrome is a rare form of syndromic primary hyperparathyroidism. We describe a young female with a history of common precursor B acute lymphoblastic leukaemia who was diagnosed with overt primary hyperparathyroidism due to a pathogenic CDC73 variant (c.25C > T).

The use of transaxillary and transsubclavian approaches for endoscopic thyroidectomy has increased globally. However, studies examining the comparative outcomes of these procedures are scarce. In this study, we aimed to compare the safety and efficacy of thyroidectomy between the gasless endoscopic thyroidectomy transaxillary approach (GETTA) and gasless endoscopic thyroidectomy transsubclavian approach (GETTSA) in patients with papillary thyroid cancer (PTC).

Parathyroid carcinoma (PC) is a rare malignancy, comprising 1 % of all cases of primary hyperparathyroidism (PHPT). This narrative review explores recent advances in PC management, with a focus on molecular insights, diagnostic advancements, surgical innovations, and emerging targeted therapies. Manuscripts published between 2023 and 2024 were obtained from PubMed, EMBASE, and the Cochrane Central Register of Controlled Trials (CENTRAL).

Background: Surgery is the preferred treatment for primary hyperparathyroidism. Minimally invasive parathyroidectomy is only feasible with accurate preoperative localisation. Virtual 3D anatomical models can be constructed from patient-specific CT scans using segmentation software.
