[The treatment and clinical therapeutic effect analysis in 59 cases of advanced supraglottic laryngeal squamous cell carcinoma].

OBJECTIVE

To compare the therapeutic effect of postoperative radiotherapy with surgery alone in advanced supraglottic laryngeal squamous cell carcinoma (LSCC).

METHOD: According to the treatment methods, 59 patients with advanced supraglottic LSCC were divided into surgery plus radiotherapy group (S+R group) (33 cases) and surgical group (S group) (26 cases). In S+R group, total laryngectomy was performed on 27 patients and partial laryngectomy on 6 patients, 27 of whom underwent lateral neck dissections; while in S group, total laryngectomy was performed on 23 patients and partial laryngectomy on 3 patients, 24 of whom underwent lateral neck dissections.

RESULT: The 3-year overall survival rate of S+R and S group were 62.6% and 62.6% respectively, and the 5-year overall survival rate of S+R and S group were 43.8% and 40.5% respectively. But there was no statistically significant difference of survival rate between two groups by Log-rank test (P > 0.05). In S+R group, recurrence happened in 5 cases and the recurrent rate was 15.1%; in S group, recurrence happened in 10 patients and the recurrent rate was 38.5%, statistically significant difference was found between the two recurrent rates (P < 0.05).

CONCLUSION

Surgery combined with postoperative radiotherapy could not improve the 3-year-or 5-year overall survival rate, but could significantly reduced tumor recurrence rate.
