Abstract

Objective:

Asian patients with laryngeal cancer have been reported to have a high prevalence of thyroid involvement. This study aimed to investigate the prevalence of thyroid invasion in Iranian patients with laryngeal cancer.

Methods:

Hospital records for all patients with a definite diagnosis of laryngeal cancer between 1996 and 2009 (351 patients) were reviewed, and the prevalence of thyroid invasion was established based on the pathology report at the time of surgery.

Results:

Thyroid invasion was found in 16 patients (4.55 percent), and was limited to one thyroid lobe in two-thirds of cases. All instances of thyroid invasion occurred in patients with stage III (81.25 percent) or IV (18.75 percent) cancer. No case of metastasis was reported. The glottic region was identified as the tumour origin in most cases of thyroid invasion (56.25 percent).

Conclusion:

Most cases of thyroid invasion by laryngeal cancer occurred in cancer stage III, at grades G1 and G2, among male patients, and arose from tumours of the glottic region.
