Long-term Nonskeletal Complications in Patients With Thyroid Cancer and Hypoparathyroidism Post Total Thyroidectomy

J Clin Endocrinol MetabPublished Retrospective cohort study

Authors' conclusion

Patients with TC with hypoP are at an increased risk for specific nonskeletal complications, particularly older adults and women. These findings underscore the need for targeted monitoring and management strategies in this population. Further prospective studies are warranted to validate these associations and elucidate the underlying mechanisms.

Study context

Population
Patients with thyroid cancer diagnosed 2006–2019, National Health Insurance Service-National Sample Cohort
Exposure
Thyroid cancer (TC) with hypoparathyroidism vs TC without hypoparathyroidism vs matched controls
  • TC with hypoPn = 430
  • TC without hypoPn = 850
Outcome
Incidence and risk of nonskeletal complications: DM, dyslipidemia, cardiovascular and renal outcomes, cataracts
Methodological detailspropensity score matching, Cox proportional hazards models, National Health Insurance Service-National Sample Cohort (2002-2019)
  • Propensity score matching
  • Cox proportional hazards models
  • National Health Insurance Service-National Sample Cohort (2002-2019)
