Resumo
[Abstract]
Objectives:
Transoral CO2 laser therapy represents the treatment of choice for early-stage laryngeal tumors. The anterior commissure involvement (ACI) is related to a worse local control and a lower rates of organ preservation. The objective of this study is to analyze the differences in survival, local control, and organ preservation in T1b glottic patients according to the presence of ACI.
Methods:
Observational prospective study in pT1b treated with transoral CO2 laser between 2009 and 2014.
Results:
Forty patients (37 male and 3 female) with a mean age of 66.43 ± 8.16 years were recruited. Anterior commissure involvement was present in 70% of the patients. The 5-year specific cause survival was 91.66%, with 32.50% of local recurrences. Laryngeal preservation was 80%, being lower in the group with local recurrence (P < .000). The involvement of the anterior commissure does not influence the organ preservation (P = .548), the appearance of local recurrences (P = .391), or the survival (P = .33).
Conclusions:
Transoral CO2 laser therapy is an effective and reproducible treatment for early-stage laryngeal tumors. The results obtained are similar to previous studies, although they present discrepancies in relation to the role of the ACI. Prospective randomized trials are required focusing also on the patients’ quality of life and functional outcome in order to clarify the role of the ACI and the need to implement changes in its evaluation, staging, and evolution.
