  • endoscopic laser surgery of early glottic cancer involvement of the Anterior Commissure
    Head and Neck-journal for The Sciences and Specialties of The Head and Neck, 2009
    Co-Authors: Ralph M W Rodel, Wolfgang Steiner, Roland M Muller, Martina Kron, Christoph Matthias

    Abstract:

    Background

    Early glottic cancer can be cured with transoral laser resection, but in cases with Anterior Commissure involvement, there is still controversy concerning the best treatment modality.

    Methods

    The impact of Anterior Commissure involvement on local control was analyzed in a retrospective review of 444 patients with early glottic cancer (pT1a–pT2a) treated between 1986 and 2004 with transoral laser microsurgical resection.

    Results

    The Anterior Commissure was involved in 153 cases; the 5-year local control rate with and without Anterior Commissure involvement was 73% versus 89% for T1a and 68% versus 86% for T1b tumors. For T2a lesions, the 5-year local control rate was 76%, irrespective of Anterior Commissure involvement.

    Conclusion

    In early glottic cancer treated by transoral laser microsurgery, a decrease in local control is evident in case of Anterior Commissure involvement for T1a and T1b but not for T2a tumors. © 2009 Wiley Periodicals, Inc. Head Neck, 2009

  • impact of Anterior Commissure involvement on local control of early glottic carcinoma treated by laser microresection
    Laryngoscope, 2004
    Co-Authors: Wolfgang Steiner, Ralph M W Rodel, Petra Ambrosch, Martina Kron

    Abstract:

    Objectives: To analyze the impact of Anterior Commissure involvement on local control, survival, and laryngeal preservation in patients with early glottic cancer (pT1a–pT2a) treated with unimodality laser microsurgical resection.

    Study Design: Retrospective review of 263 patients with early glottic cancer treated between 1986 and 1996.

    Methods: Data on local control and overall survival rates were analyzed and calculated by the Kaplan-Meier method; the larynx preservation rates were given absolutely.

    Results: Among 158 patients presenting with T1a glottic cancer, the Anterior Commissure was involved in 28 cases; the 5-year local control rate was 84%, and the larynx preservation rate was 93%. In the 130 cases without Anterior Commissure involvement, the 5-year local control rate was 90.0% and the corresponding larynx preservation rate 99%. In the T1b category consisting of 30 patients, Anterior Commissure involvement was observed in 16 patients; the 5-year local control rate was 73%, and the larynx preservation rate was 88%. In the 14 cases without Anterior Commissure involvement, the 5-year local control rate was 92% and the corresponding larynx preservation rate 100%. Seventy-five patients had T2a glottic carcinomas, with normal vocal cord movement. The Anterior Commissure was involved in 45 cases; the 5-year local control rate was 79%, and the larynx preservation rate was 93%. In the 30 cases without Anterior Commissure involvement, the 5-year local control rate was 74.0% and the corresponding larynx preservation rate 97%.

    Conclusions: This study shows the effectiveness of laser microsurgery for early glottic carcinoma regardless of Anterior Commissure involvement at presentation. This method can be performed as an outpatient procedure, even when conducting reresections.
