Well-differentiated thyroid carcinoma rarely invades the upper aerodigestive tract, but can cause severe symptoms. Surgical techniques and adjuvant therapies can preserve function and reduce recurrence.

Area of Science:

  • Oncology
  • Otorhinolaryngology
  • Head and Neck Surgery

Background:

  • Well-differentiated thyroid carcinoma (WDTC) infrequently invades the upper aerodigestive tract (UADT).
  • UADT invasion by WDTC leads to significant morbidity and mortality.
  • Commonly invaded structures include recurrent laryngeal nerves, larynx, pharynx, and esophagus, causing airway insufficiency, dysphagia, and hemoptysis.

Purpose of the Study:

  • To review the management of locally invasive thyroid carcinoma involving the UADT.
  • To highlight organ-preserving surgical techniques and adjuvant therapies.

Main Methods:

  • Review of literature on WDTC with UADT invasion.
  • Analysis of surgical approaches and adjuvant treatment modalities.

Main Results:

  • Tumors limited to the laryngeal or tracheal wall without intraluminal extension can be managed with "shaving" for comparable local control to radical procedures.
  • Intraluminal extension necessitates resection of the aerodigestive tract, but function-preserving partial resections are often feasible.
  • Adjuvant radioiodine or external beam radiotherapy significantly reduces local recurrence rates and controls symptomatic disease.

Conclusions:

  • Locally invasive thyroid carcinoma of the UADT can often be treated with function preservation.
  • Organ-preserving surgery combined with adjuvant radiotherapy is crucial for optimal outcomes.
  • Multidisciplinary management is essential for these complex cases.
