Larynx preservation clinical trial design: key issues and recommendations--a consensus panel summary

Area of Science:

• Oncology
• Clinical Trial Design
• Head and Neck Cancer Research

Background:

• Developing guidelines for Phase III clinical trials focused on larynx preservation in locally advanced laryngeal and hypopharyngeal cancer.
• Addressing the need for standardized methodologies to evaluate novel treatment options effectively.

Framework:

• Recommendations developed by a multidisciplinary international consensus panel.
• Review of completed Phase III randomized trials, meta-analyses, and clinical reports up to November 2007.

Implementation:

• Trial population: T2-T3 laryngeal/hypopharyngeal squamous cell carcinoma, not candidates for partial laryngectomy, excluding those with laryngeal dysfunction or age >70.
• Functional assessments: Speech, swallowing, and routine voice assessment using validated instruments.
• Primary endpoint: Laryngo-esophageal dysfunction-free survival (death, relapse, laryngectomy, tracheotomy, or feeding tube dependency at ≥2 years).

Implications:

• Revised trial designs are crucial for advancing larynx preservation research.
• Consistent methodologies will enable more effective evaluation of therapeutic benefits.
• Standardized outcome measures will improve the comparison of novel treatment options.
