Background:  We aimed to provide a pooled analysis of controlled trials comparing long-term survival after primary laryngectomy and primary organ preservation methods in patients with T3-4 laryngeal cancer.    Methods:  We performed random-effects meta-analyses on overall survival (OS), disease-free survival (DFS), disease-specific survival (DSS), and locoregional control (LRC).    Results:  Fifteen studies met the selection criteria including 6288 patients (2696 patients who underwent primary laryngectomy and 3592 patients who underwent primary nonsurgical organ preservation therapy). There was a significant difference between the groups with respect to OS (HR 0.71, 95% CI 0.57–0.89,  P =  .003). However, a subgroup analysis found OS was not significantly worse for patients with T3 laryngeal cancer who received primary organ preservation compared with patients who underwent primary laryngectomy (HR 0.96, 95% CI 0.45–2.03,  P =  .91). There was no significant difference for DFS (HR 0.63, 95% CI 0.39–1.04,  P =  .07) in two groups. Patients with laryngeal cancer who underwent primary laryngectomy had a better DSS (HR 0.47, 95% CI 0.25–0.88,  P =  .02) and LRC (HR 0.56, 95% CI 0.390.80,  P =  .001) than patients who underwent primary nonsurgical organ preservation therapy.    Conclusion:  Our results support total laryngectomy for patients with T4 laryngeal cancer and show that primary organ preservation for laryngeal cancer has no advantage and also did not decrease the rate of OS in patients with T3 laryngeal cancer when compared with primary total laryngectomy.
