CO(2) laser endoscopic surgery offers excellent oncological outcomes for early glottic cancer. This minimally invasive approach provides high local control and laryngeal preservation rates, establishing it as a gold standard treatment.

Area of Science:

  • Otolaryngology
  • Oncology
  • Minimally Invasive Surgery

Background:

  • Early-stage glottic carcinoma requires effective treatment with minimal morbidity.
  • Endoscopic surgery using CO(2) laser presents a promising minimally invasive option.

Purpose of the Study:

  • To evaluate the oncological results of CO(2) laser-assisted endoscopic surgery for early glottic carcinomas.
  • To identify prognostic factors influencing local control and disease-free survival (DFS).

Main Methods:

  • Retrospective analysis of 177 patients with pT1-T2 glottic carcinomas treated between 2000-2007.
  • Minimum 24-month follow-up (mean 49.1 months) to assess oncological outcomes.
  • Focus on local control, disease-specific survival (DSS), and laryngeal preservation.

Main Results:

  • High overall survival (90.8%) and disease-specific survival (98.8%) rates.
  • Local control rates: 86.3% primary, 94.3% ultimate with laser alone.
  • Laryngeal preservation rate of 97.7%.
  • Arytenoid involvement and limited subglottic extension significantly impacted DFS.

Conclusions:

  • CO(2) laser endoscopic surgery is the gold standard for early glottic carcinoma.
  • Benefits include high local control, day surgery, low morbidity, good voice outcomes, and cost-effectiveness.
  • Prognostic factors like arytenoid and subglottic involvement require careful consideration.
