Abstract:
Objective:To investigate optimal treatment strategy for pT3N0 laryngeal squamous cell carcinoma（SCC）. Methods:A retrospective study of 150 patients with pT3N0 laryngeal SCC treated in the First Affiliated Hospital of Chongqing Medical University was performed. The efficacies of partial laryngectomy and total laryngectomy, as well as surgery alone and postoperative radiotherapy were evaluated. The overall survival（OS）, disease specific survival（DSS） and disease-free survival（DFS） were analyzed with statistical package from SPSS. Results:Among the 108 patients with glottic laryngeal SCC, there were no significant differences in OS, DSS and DFS between the partial laryngectomy group and the total laryngectomy group（Log-rank=0.184, 0.010 and 0.051, P>0.05）. Similarly, there were no significant differences in OS, DSS and DFS between the surgery-alone group and postoperative radiotherapy group（Log-rank=0.214, 0.251 and 0.003, P>0.05）. Among the 38 patients with supraglottic laryngeal SCC, the OS in the total laryngectomy group was significantly higher than that in the partial laryngectomy group（Log-rank=7.338, P=0.007）. The DSS and DFS in the total laryngectomy group were higher than in the partial laryngectomy group, but the differences were not statistically significant（Log-rank=0.895 and 1.792; P>0.05）. The DFS in the postoperative radiotherapy group was significantly higher than in the surgery-alone group（Log-rank=7.172, P=0.007）, but there were no significant differences in OS and DSS between these two groups（Log-rank=0.010 and 0.876, P>0.05）. Conclusion:For pT3N0 glottic laryngeal cancer patients, the efficacy of partial laryngectomy is comparable to total laryngectomy, same as surgery alone and postoperative radiotherapy. For pT3N0 supraglottic laryngeal cancer patients, total laryngectomy could improve the overall survival, and postoperative radiotherapy could reduce the recurrence. Prospectively randomized study with large samples is still needed.
