Primary radiation therapy for early glottic cancer
1Department of Otolaryngology and Communicative Disorders, Cleveland Clinic Foundation, OH 44195, USA.
Summary
Primary radiation therapy offers good local control for early glottic cancer. However, voice-sparing salvage surgery after radiation failure, such as vertical hemilaryngectomy (VHL), has limited success.
Area of Science:
- Otolaryngology
- Radiation Oncology
- Head and Neck Surgery
Background:
- Early glottic squamous cell carcinoma is treatable with radiation or surgery.
- Evaluating outcomes of primary radiation and salvage surgery is crucial.
Purpose of the Study:
- To assess the efficacy of primary radiation therapy for early glottic cancer.
- To evaluate the success of vertical hemilaryngectomy (VHL) as a salvage procedure.
Main Methods:
- Retrospective review of 45 patients with early glottic squamous cell carcinoma treated between 1986-1994.
- Analysis of local control rates after radiation and outcomes of salvage surgeries.
Main Results:
- Overall local control rate after radiation was 80% (87.5% for T1, 75% for T2).
- Only 1 of 4 patients undergoing VHL salvage after recurrence was successful.
- All 5 patients requiring total laryngectomy salvage after radiation were successfully treated.
Conclusions:
- Primary radiation therapy achieves local control rates comparable to existing literature.
- Voice-sparing salvage options, including VHL, demonstrate poor success rates after radiation failure.
