INTRODUCTION: In many regions, laryngeal carcinoma is a common upper respiratory tract cancer, most commonly involving the glottic region. The treatment of early glottic cancer includes radiotherapy, open surgery and laryngeal laser microsurgery. However, the preferred treatment for early glottic cancer is still controversial.
OBJECTIVES: To study the factors affecting the 5-year survival rate of Tis-2N0M0 early glottis cancer and to demonstrate the oncological safety of different treatments.
METHODS: 144 patients with early glottic cancer were analyzed retrospectively. All patients were clinically node negative. 53 patients underwent open surgery, transoral CO2 laser microsurgery in 46 cases and radiotherapy in 45 cases. The patients were followed up for 26 - 84 months, with an average follow-up period of 62.9 months.
RESULTS: The 5-year overall survival was 82.6%. The 5 year survival rates of open surgery, laser microsurgery and radiotherapy were 83.0%, 82.6% and 82.2%, respectively. There was no significant difference in 5-year survival rate among the three treatments (p = 0.987). In multivariate analysis, age, T-stage, pathological grading, and anterior commissure involvement were important prognostic factors for early glottic cancer.
CONCLUSION: There was no significant difference in 5 year survival rate among patients treated by either radiotherapy, laser microsurgery or open surgery for early glottic cancer. We urge more attention to the age, T-stage, pathological grade, and anterior commissure involvement of the patients.
