Abstract
The purpose of this study was to assess the validity of CO2 laser cordectomy in the treatment of early glottic cancer and to determine the impact of margin status on disease-free survival and of the operation on voice quality. This is a retrospective review of 169 patients. Quantitative and qualitative variables were statistically compared. The impact on overall and disease-free survivals of different variables was calculated by univariate and multivariate analyses. Ten-year overall and disease free-survivals were 75 % and 60 %, respectively. Age and clinical stage showed a significant negative impact on overall survival, while margin status both on overall and disease-free survivals. The degree of dysphonia was directly related to the extension of the resection. This series confirms the good oncologic and functional outcomes of laser surgery for Tis, T1 and selected T2 glottic tumors. Patients with positive margins should undergo a further treatment or a very close follow-up.
