Abstract
BACKGROUND Cervical thymectomy is commonly performed during parathyroidectomy for primary hyperparathyroidism in multiple endocrine neoplasia type 1. Recently, there have been several single-institutional studies that have found no added benefit to the addition of thymectomy and question its impact on postoperative outcomes. We aimed to evaluate the outcomes of concomitant cervical thymectomy in multiple endocrine neoplasia type 1 patients undergoing parathyroidectomy for primary hyperparathyroidism using a large cohort of patients.
METHODS This retrospective study used the TriNetX research platform, a global collaborative network representing over 130 million patients. We identified 434 patients with multiple endocrine neoplasia type 1 who underwent parathyroidectomy with and without cervical thymectomy. Outcomes assessed between 129 cases of thymectomy and 305 controls without thymectomy include rates of reoperation, cure, persistent and recurrent disease, and transient and permanent hypoparathyroidism.
RESULTS Adding cervical thymectomy to parathyroidectomy was associated with higher cure rates (96.9% vs 88.2%; P = .004), demonstrating a 74% reduction in the risk of persistent disease (relative risk, 0.26; 95% confidence interval, 0.10-0.72) when compared with that of parathyroidectomy alone. While transient hypoparathyroidism rates rose with the addition of thymectomy (38.0% vs 24.3%; P= .017), there was no significant difference in the rate of permanent hypoparathyroidism (3.1% vs 1.6%; P = .328).
CONCLUSION Adding cervical thymectomy to parathyroidectomy during the surgical management of multiple endocrine neoplasia type 1 patients with primary hyperparathyroidism is associated with higher cure rates without a significant increase in permanent complications. Cervical thymectomy should, therefore, be considered a standard component of care for multiple endocrine neoplasia type 1 patients undergoing parathyroidectomy for primary hyperparathyroidism.
