Brief Summary
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.

Study Arms (2)
Vocal-cord Radiotherapy
EXPERIMENTALComplete Larynx Radiotherapy
ACTIVE COMPARATORInterventions
Focal radiotherapy limited to the involved vocal cord(s) plus additional margins accounting for respiration and set-up errors.
Radiotherapy to the entire larynx, with target volumes defined to lead to traditional volumes from conventional complete larynx radiotherapy.
Eligibility Criteria
You may qualify if:
- Stage T1a-b N0 of the true vocal cords planned for definitive RT
- Patient not candidate for laser surgery or declined laser surgery
- Biopsy-confirmed squamous cell carcinoma, including verrucous carcinoma
- Eastern Cooperative Oncology Group performance status 0-2
- Ability to provide written informed consent.
You may not qualify if:
- Previous irradiation of the head and neck (HNC) region
- Pregnancy or breastfeeding
- Any medical condition that represents, in the opinion of the investigator, a contraindication to radiotherapy or would prevent follow-up after radiotherapy.
- Prior invasive malignancy (except non-melanomatous skin cancer) unless disease free for a minimum of 2 years.
