Regular postoperative thyroxine (thyroid hormone) administration, especially at higher doses (≥0.15 mg/day), significantly reduces nontoxic goitre recurrence after surgery. This is crucial in iodine-deficient regions like Turkey.

Area of Science:

  • Endocrinology
  • Surgical Oncology
  • Public Health

Background:

  • Nontoxic goitre is a prevalent condition, particularly in iodine-deficient areas.
  • Postoperative recurrence of nontoxic goitre poses a significant clinical challenge.
  • Understanding factors influencing recurrence is vital for effective patient management.

Purpose of the Study:

  • To investigate the incidence and recurrence rates of nontoxic goitre after surgery.
  • To evaluate the impact of postoperative thyroxine (thyroid hormone) administration on recurrence.
  • To determine optimal thyroxine dosage and regularity for preventing goitre recurrence.

Main Methods:

  • A cohort study involving 206 patients who underwent surgery for nontoxic goitre.
  • Long-term postoperative follow-up with a mean observation period of 7.8 years.

  • Analysis of recurrence rates based on varying thyroxine administration protocols (dosage, regularity) and comparison with no thyroxine use.
  • Main Results:

    • The recurrence rate was lowest (30.7%) in patients receiving regular high-dose (≥0.15 mg/day) thyroxine.
    • Higher recurrence rates were observed with regular low-dose thyroxine (46.9%), irregular use (71.4%), and no thyroxine (81.8%).
    • Regular, higher-dose thyroxine significantly reduced recurrence compared to irregular or no thyroxine use.

    Conclusions:

    • Postoperative thyroxine administration is essential for reducing nontoxic goitre recurrence.
    • Regular administration of thyroxine at doses of 0.15 mg/day or more is most effective.
    • Iodine deficiency in regions like Turkey underscores the importance of this postoperative management strategy.
