Introduction:
Squamous cell carcinoma (SCC) of the vocal cord in stages I or II can be treated with radiotherapy (RT) or transoral CO2 laser microsurgery (TLM), with good oncological results.
Objectives:
To study the survival of patients with SCC of the vocal cord in early stages, treated with RT or TLM, in a tertiary hospital.
Material And Methods:
Disease-free survival (DFS), specific survival (SS), and overall survival (OS) were studied in patients diagnosed with stage I and II SCC of the vocal cord, for a span of 10 years of follow-up, based on sociodemographic characteristics of the patient and the primary treatment (TLM or RT).
Results:
Both treatments achieved good survival rates. However, long-term SS was greater in patients treated with TLM compared to those treated with RT (91.7% vs. 50%, respectively, p = .001). In addition, patients treated with TLM presented a higher OS in the short term than those treated with RT (99.0% vs. 89.1%, respectively. p = .004).
Conclusions And Significance:
Primary treatment with TLM obtained better results than RT in the survival of patients with SCC of the vocal cord in the early stages.
