PURPOSE: The aim of this study was to evaluate the influence of preoperative tracheotomy on oncologic outcomes of advanced stage glottic carcinoma patients, and to explore the potential reason. METHODS: We retrospectively analyzed 413 consecutive advanced stage glottic carcinoma patients from January 2005 to December 2010. The correlation of preoperative tracheotomy and potential impacting factor of tumor size involving tumor diameter and tumor area with overall survival (OS) and disease-free survival (DFS) was fully assessed. RESULTS: Our cohort consisted of 302 (73.1%) patients with T3 and 111 (26.9%) patients with T4, and 98 (23.7%) patients received preoperative tracheotomy. The OS and DFS rates of patients receiving preoperative tracheotomy were worse than those without (5-year OS: 49.3% versus 69.8%; 5-year DFS: 45.3% versus 61.0%). The mean tumor diameter and tumor area of patients with preoperative tracheotomy were greater than those without (3.3 cm versus 2.4 cm, 8.9 cm2 versus 4.7 cm2). The optimal cutoff values of tumor diameter and tumor area for tracheotomy were 2.85 cm and 6.64 cm2. Tumor diameter and tumor area were correlated with tracheotomy intervention. Furthermore, when considering the potential effect of tumor area in multivariate model, we found that it was a significant factor in survival outcomes but variable of preoperative tracheotomy was not. CONCLUSION: This study indicates that tumor size is correlated with preoperative tracheotomy, and tracheotomy intervention may be reflection from effect of great tumor size that is a true adverse factor influencing oncologic outcomes of advanced stage glottic carcinoma patients.
