Context:
Primary hyperparathyroidism (PHPT) is the earliest and most frequent manifestation of multiple endocrine neoplasia type 1 (MEN1). The optimal surgical extent remains controversial due to the tradeoff between recurrence and permanent hypoparathyroidism.
Objective:
To evaluate outcomes of different surgical approaches in MEN1-related PHPT and assess preoperative biochemical predictors through systematic review and meta-analysis.
Data Sources:
MEDLINE, PubMed, Embase.com, LILACS, and CENTRAL were searched from inception to April 2025, following PRISMA guidelines (PROSPERO: CRD420251027970).
Study Selection:
We included studies on adult MEN1-related PHPT patients undergoing parathyroidectomy with reported recurrence, hypoparathyroidism, and preoperative biochemical data.
Data Extraction:
Two reviewers independently extracted data and assessed study quality. Random-effects models were used to pool risk ratios (RR) with 95% confidence intervals (CI). Meta-regression evaluated associations with preoperative PTH, calcium, and phosphorus.
Data Synthesis:
Thirteen studies (915 patients) were included. Less-than-subtotal parathyroidectomy (
Conclusion:
Conservative surgery reduces hypoparathyroidism but increases recurrence. Personalized surgical strategies are essential in MEN1-related PHPT.
