5-year total laryngectomy-free survival curve by treatment group. This survival curve depicts the 5-year total laryngectomy-free survival for all patients reported in this study, and is divided by treatment group, TLM and RT. No statistically significant relationship was observed between treatment group and 5-year survival (χ 2 = 0.289, p = 0.591). Censored patients are those whose did not receive a total laryngectomy, nor did they die from their primary cancer, but were lost to follow-up before the 5-year mark
