Objective: To determine the prevalence of, and describe transglottic cancer with thyroid cartilage invasion as a possible risk for, thyroid gland invasion in a series of patients with laryngeal carcinoma who underwent total laryngectomy with thyroidectomy.
Methods
Study Design: Retrospective case series
Setting: Tertiary government hospital
Subjects: 61 laryngeal carcinoma patients who underwent total laryngectomy with hemi- or total thyroidectomy from January 2010 to August 2017.
Results
Out of 61 patients with laryngeal carcinoma, 11 patients had supraglottic, 11 glottic, 2 subglottic and 37 had transglottic involvement. Eleven had thyroid cartilage invasion, all of whom had transglottic tumors. Of these 11 patients, only 1 had thyroid gland invasion. This was a case of a 78 year-old male patient, with poorly differentiated SCC stage IVa transglottic tumor with thyroid cartilage invasion.
Conclusion
Thyroid gland invasion was uncommon in our sample of laryngeal carcinoma patients who underwent laryngectomy and thyroidectomy. Although transglottic involvement with thyroid cartilage invasion may increase the risk of thyroid gland invasion, it could not be confirmed by our series. Perhaps thyroidectomy should not be routinely performed on all patients with laryngeal carcinoma who undergo total laryngectomy, but more rigorous studies are needed to establish this.
