[Long-term treatment outcome in patients undergoing cricohyoidoepiglottopexy for glottic carcinoma].

OBJECTIVE

To investigate the long-term results of cricohyoidoepiglottopexy(CHEP) in the treatment of glottic carcinoma.

METHODS

A retrospective chart review of 92 consecutive patients who underwent CHEP in the selected institut from January 1990 to December 2008. Of the 92 cases, 41 cases of stage I, 39 cases of stage II, 12 cases of stage III. The time for the decannulation and the removal of the nasal feeding and quality of phonation were used for evaluating postoperative functional rehabilitation. The estimated long-term survival rates were calculated by Kaplan-Meier method.

RESULTS

Among 92 patients, 26 cases (27 sides) received neck dissection and lymph nodes were pathologically positive in 3 patients (11.1%). All final surgical margins were negative for tumor invasion. Seven patients had postoperative radiotherapy and one had chemoradiation. Thirteen patients (14.1%) were found local recurrence and nine patients (9.8%) had postoperative metastases. Overall 3-, 5- and 10-year survival rates were 90.0%, 84.5% and 67.0% respectively. Cox multivariate analysis showed that the recurrence had significant influences on the overall survival rate.

CONCLUSION

CHEP not only is relatively easy to master, but also effective in the treatment of glottic carcinoma.
