Endoscopic Surgery or Radiation Therapy in Treating Patients With Stage 0, Stage I, or Stage II Laryngeal Cancer of the Glottis

This study has been completed.

National Cancer Institute (NCI) Identifier:

Last verified: March 2009

RATIONALE: Endoscopic surgery is a less invasive type of surgery for laryngeal cancer and may have fewer side effects and improve recovery. Radiation therapy uses high-energy x-rays to kill tumor cells. It is not yet known whether endoscopic surgery is more effective than radiation therapy in treating laryngeal cancer of the glottis.

PURPOSE: This randomized phase II trial is studying endoscopic surgery to see how well it works compared with radiation therapy in treating patients with stage 0, stage I, or stage II laryngeal cancer of the glottis.

Condition Intervention Phase
Head and Neck Cancer Procedure: endoscopic surgery Procedure: laser surgery Radiation: radiation therapy Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Primary Purpose: Treatment
Official Title: Early Stage Glottic Cancer: Endoscopic Excision or Radiotherapy [EaStER]

Primary Outcome Measures:
  • Feasibility
  • Patient acceptability

Secondary Outcome Measures:
  • Voice analysis
  • Quality of life
  • Economic assessment

Estimated Enrollment: 50
Study Start Date: September 2005
Study Completion Date: July 2006
Detailed Description:


  • Determine the feasibility of conducting a large phase III randomized study in the future, comparing radiotherapy vs endoscopic excision in patients with stage 0-II laryngeal cancer of the glottis.
  • Determine patient acceptability of the proposed trial design.
  • Compare the effect of using dedicated head and neck research nurses vs general nurses on patient recruitment.
  • Refine outcome measures, including voice analysis and quality of life.

OUTLINE: This is a randomized, controlled, multicenter, pilot study. Patients are stratified according to participating center and T stage (Tis or T1 vs T2a). Patients are randomized to 1 of 2 treatment arms.

  • Arm I: Patients undergo endoscopic excision via CO_2 laser or cold steel.
  • Arm II: Patients undergo radiotherapy once daily, 5 days a week, for 3-4 weeks. Patients undergo vocal analysis at baseline and at 6 months and 1 and 2 years after randomization.

Quality of life is assessed at baseline, at 1 year, and then annually for 5 years.

After completion of study treatment, patients are followed periodically for up to 5 years.
