Vocal-cord vs. Complete Laryngeal Radiotherapy for Early Glottic Cancer (VOCAL)
December 11, 2023 updated by: Centre hospitalier de l'Université de Montréal (CHUM)
A Randomized Study of Vocal-cord Only vs. Complete Laryngeal Radiotherapy for Early Glottic Cancer
This is a multicentrer, randomized Bayesian Phase II trial for patients with early stage (T1N0) glottic squamous cell carcinoma treated with radical radiotherapy.
The primary objective is to assess the non-inferiority of local control achieved with vocal-cord only radiotherapy (VC-RT) compared to complete larynx radiotherapy (CL-RT) in T1N0 glottic laryngeal squamous cell cancer, measured at 2-years after treatment.
Secondary outcomes include overall survival, as well as voice impairment, dysphagia and quality of life, measured respectively by the voice handicap index -10 (VHI-10), the MD Anderson Dysphagia Inventory (MDADI) and the MD Anderson Symptom Inventory- Head and Neck module (MDASI-HN).
Patients will be randomized in a 1:3 ratio to CL-RT (39 patients) and VC-RT (116 patients) arms.
There will be stratification by tumor stage (T1a/T1b) and by institution.
An interim analysis is planned after the first 55 patients enrolled on the experimental arm have a 6-month follow-up.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Vocal-cord Radiotherapy
|
Focal radiotherapy limited to the involved vocal cord(s) plus additional margins accounting for respiration and set-up errors.
|
Active Comparator: Complete Larynx Radiotherapy
|
Radiotherapy to the entire larynx, with target volumes defined to lead to traditional volumes from conventional complete larynx radiotherapy.

Measure Description |
Time Frame |
---|---|---|
Voice Handicap Index-10 score
Time Frame: Week 0 post-treatment, and at 2-month, 6-month, 1-year and 2-year follow-up
|
Scores are rated on a 0-4 scale to indicate the presence and severity of the symptoms.
Lower scores represent better functioning and quality of life.
|
Week 0 post-treatment, and at 2-month, 6-month, 1-year and 2-year follow-up
|
MD Anderson Dysphagia Inventory score
Time Frame: Week 0 post-treatment, and at 2-month, 6-month, 1-year and 2-year follow-up
|
Overall score ranges from 0 to 100, with higher score representing better functioning and quality of life.
|
Week 0 post-treatment, and at 2-month, 6-month, 1-year and 2-year follow-up
|
MD Anderson Symptom Inventory-Head & Neck score
Time Frame: Week 0 post-treatment, and at 2-month, 6-month, 1-year and 2-year follow-up
|
The core and head and neck cancer specific symptoms are rated on a 0-10 scale to indicate the presence and severity of the symptoms.
Lower scores represent better functioning and quality of life.
|
Week 0 post-treatment, and at 2-month, 6-month, 1-year and 2-year follow-up
|
Consensus Auditory-Perceptual Evaluation of Voice (CAPE-V)
Time Frame: Week 0 post-treatment and at 6-month follow-up
