[Surgical treatment of differentiated thyroid carcinoma with laryngeal or tracheal invasion]
Objective:
To analyze the clinical characters, surgical treatments and prognosis of differentiated thyroid carcinoma (DTC) with laryngeal or tracheal invasion.
Method:
Forty-six cases including 33 papillary and 13 follicular were retrospectively reviewed. Thirty-four cases with tracheal invasion received conservative resection (17), window resection (11) and sleeve resection (6). One case with subglottic invasion was performed subglottic partial laryngectomy. Eleven cases with trachea-laryngeal invasion received total laryngectomy(4), 3 shave technique and 4 preservative laryngectomy.
Result:
Complications included infections and hypocalcaemia, 15 patients got permanent fistula. 5-year survival rate in cases of tracheal shave resection was 88.2%, while 63.6% in those of window resection and 83.3% in those of sleeve resection. Survival rate within 5 years of patients received preservative laryngectomy was 62. 5%. Conclusion: With meticulous preoperative examination and positive surgical treatment, both survival rate and quality of life could be improved in patients of DTC with laryngeal or tracheal invasion.
