Long-term recurrence after parathyroidectomy in primary hyperparathyroidism-do predictors exist?

Area of Science:

• Endocrinology
• Surgical Oncology
• Nephrology

Background:

• Primary hyperparathyroidism (pHPT) is a common endocrine disorder, primarily affecting postmenopausal women.
• Most pHPT cases result from parathyroid adenoma, leading to excessive parathyroid hormone (PTH) and calcium levels.
• While historically low, recent data indicate higher rates of recurrence after parathyroidectomy, necessitating re-evaluation of long-term outcomes.

Purpose of the Study:

• To assess the long-term outcomes of parathyroidectomy for pHPT.
• To investigate factors predicting late recurrence after surgery.
• To inform the development of postoperative surveillance strategies.

Main Methods:

• Retrospective analysis of 111 patients undergoing parathyroidectomy for pHPT between 2007 and 2017.
• Long-term follow-up data collected for a median of 41 months on 65 patients.
• Evaluation of postoperative laboratory values and clinical outcomes.

Main Results:

• Elevated calcium or PTH concentrations beyond 10 years post-surgery may indicate late recurrence.
• Preoperative serum creatinine, not preoperative PTH or calcium, was identified as a predictor of long-term follow-up outcomes.
• Early postoperative normocalcemic PTH fluctuations are a known phenomenon, but long-term indicators require further study.

Conclusions:

• Long-term surveillance is essential for patients treated with parathyroidectomy for pHPT.
• Identifying predictors of late recurrence can refine postoperative monitoring protocols.
• This study contributes to understanding long-term disease management and surveillance after parathyroidectomy.
