| Abstract | Background: Laryngeal cancer is known as the second most common airway cancer. These tumors are usually diagnosed early; thus, it is important to choose the optimal treatment modality. Several studies are comparing transoral laser microsurgery (TLM) and radiotherapy in early-stage laryngeal cancer. Due to a paucity of high-quality research and the lack of conclusive randomized prospective studies, standard care for early glottic cancer is still a matter of controversy. Methods: In this retrospective cohort study, T1-T2N0M0 laryngeal cancer patients who underwent TLM or radiotherapy were compared with statistical methods in terms of Recurrence Rate, Organ (Larynx) Preservation Rate, Mortality Rate, and Overall Survival. Results: A total of 123 patients were evaluated in this study, 65 of whom underwent TLM and 58 underwent radiotherapy. There was no significant difference in demographic and medical characteristics of patients. The rate of recurrence was 27.3% in the TLM group and 43.6% in the radiotherapy group. There was no significant difference between the two groups (P = 0.114). Overall mortality rate (5.4% vs 39.6%, P = 0.001), Disease-specific mortality rate (5.5% vs 39.9%, P = 0.001), and aorgan preservation rate (98.5%vs 89.7%, P = 0.035) were all in favor of TLM. Conclusions: TLM appears to be the treatment of choice in patients with early laryngeal cancer due to a better overall survival rate, lower disease-specific mortality rate, and better organ preservation rate than definitive radiotherapy. | en |
