Surgical treatment of advanced laryngeal cancer with preservation of laryngeal function / 中华耳鼻咽喉头颈外科杂志

ABSTRACT

<p><b>OBJECTIVE</b>To explore the surgical methods for advanced laryngeal cancer and long term effects of laryngectomy.</p><p><b>METHODS</b>Two hundred and thirty-eight cases of laryngeal cancer at different stages, including 103 cases with supraglottic cancer, 118 cases with glottic cancer, 3 cases with subglottic cancer, and 14 cases with recurrent cancer, underwent different kinds of operation from 2000 to 2010. The TNM classifications were as follows T3 168 cases, T4 70 cases. Stage III 145 cases, Stage IV 93 cases. N0 134 cases,N1 64 cases,N2 38 cases, and N3 2 cases. The effects of operation, especially with the preservation of laryngeal function, was analyzed. The disease-free survival rate was calculated by Kaplan-Meier methods.</p><p><b>RESULTS</b>Partial laryngectomy was performed on 142 of the 238 cases (59.7%). Total laryngectomy was performed on 96 cases. In 142 patients who received partial laryngectomy with preservation of laryngeal function, the trachea cannula was extracted in 90 patients, with the decannulation rate as 63.4%. The nasal feeding tube was removed and peroral feeding was recovered in all patients. The patients undergoing partial laryngectomy succeeded in phonation. The 3 years and 5 years disease-free survival rates in all patients were 81.4% and 59.5%. The 3 years and 5 years disease-free survival rate of partial laryngectomy were 82.9% and 64.3%. The 3 years and 5 years disease-free survival rates in total laryngectomy were 79.2% and 52.4%. There was no significantly different between the two groups (χ(2) = 2.478, P = 0.115).</p><p><b>CONCLUSION</b>For the advanced laryngeal cancer, it is possible to preserve the laryngeal function without compromising the remote survival rate by detailed pre-operational estimation, properly selected operation and skilled surgical practice.</p>
