Revisiting parathyroid carcinoma through the lens of the 2022 WHO classification
摘要
Parathyroid carcinoma is a rare endocrine malignancy. This study aimed to evaluate the clinical characteristics, treatment approaches, and follow-up data of patients diagnosed with parathyroid carcinoma. Additionally, pathological findings were reassessed according to the 2022 World Health Organization (WHO) classification to examine its clinical implications.
MethodsThe medical records of patients who were pathologically diagnosed with parathyroid carcinoma at the Endocrinology Clinic of a University Hospital between March 2013 and June 2024 were retrospectively reviewed. Clinical characteristics, demographic data, and laboratory findings were recorded. Pathological features were also obtained retrospectively from medical charts and records.
ResultsWe reported eight patients with surgical and pathological diagnoses of parathyroid carcinoma. Six of the patients were females and two were males. The ages of the patients ranged from 43 to 85, with a mean age of 61. The follow-up periods after diagnosis varied from 6 to 132 months. The calcium levels at diagnosis ranged from 11.7 mg/dL to 18.4 mg/dL, with a median of 16.0 mg/dL (normal range 8.6–10.2 mg/dL). The median PTH level at admission was 1609 ng/L (487.7–3035 ng/L) (normal range: 15–65 ng/L). Re-evaluation of all patients based on the 2022 WHO classification revealed no changes in initial diagnoses.
ConclusionsSurgical resection remains the cornerstone of effective treatment. Accurate preoperative assessment, including detailed clinical and biochemical evaluation, is essential for optimal management. Sharing comprehensive data with pathologists enhances diagnostic accuracy. This study emphasizes the relevance of preoperative indicators and highlights that the updated WHO classification supports existing diagnostic criteria without altering clinical practice.
