Cirurgia laser CO2 no tratamento de tumores malignos glóticos

Introduction: Transoral laser microsurgery (TLM) can be considered a valid alternative in the treatment of glottic cancer. Matherial and Methods: Retrospective study, considering all patients treated with TLM, from January 2000 to December 2005. Patients were considered for the present study if they underwent laser surgery as primary treatment of glottic cancer. Results: 45 patients: CIS (n=9), T1a (n=29), T1b (n=5), T2 (n=1), T3 (n=1). The mean duration of follow-up was 63,3 months. The rate of global local recurrence was 22,2%, with the anterior commissure involvement being responsible for 40% of the recurrences. The 5-year overall survival and the 5-year disease-free survival were 82,2%, and the laryngeal preservation rate was 89,2%. Conclusion: This study supports the role of TLM in treating early-stage glottic cancer. The highest recurrence rates occur with positive margins and anterior commissure involvement. Advanced glottic cancers are not a consensual indication for laser surgery, usually with worse oncological outcome.
