Summary
Endoscopic laser surgery offers a convenient and cost-effective treatment for laryngeal cancer. This study shows comparable results to radiation therapy with good voice quality and high survival rates.
Area of Science:
- Otolaryngology
- Oncology
- Minimally Invasive Surgery
Background:
- Endoscopic laser surgery is an emerging treatment for laryngeal cancer.
- The CO2 laser with an operating microscope is the standard instrumentation.
- Large-scale implementation in Finland began in 1994 across five university hospitals.
Purpose of the Study:
- To evaluate the efficacy and outcomes of endoscopic laser surgery for laryngeal cancer.
- To analyze recurrence rates, survival, and voice quality post-treatment.
- To compare laser surgery outcomes with established therapies like radiation.
Main Methods:
- Analysis of 140 patients treated with endoscopic laser surgery between 1994 and 1998.
- Inclusion of 132 patients with in situ, stage I, or stage II tumors for recurrence and survival analysis.
- Mean follow-up of 38 months, with specific attention to recurrence after 2 years.
Main Results:
- Two-year recurrence rates were 5% for stage I, 31% for stage II, and 11% overall.
- No recurrences were observed beyond the 2-year mark.
- Adjusted cumulative survival rate was 95%, with 70% of patients reporting good or excellent voice quality.
Conclusions:
- Endoscopic laser surgery provides outcomes comparable to radiation therapy for laryngeal cancer.
- The procedure offers patient convenience and societal cost-effectiveness.
- High survival rates and preserved voice quality make it a favorable treatment option.
