Dose De-escalation to the Elective Nodal Sites in Head and Neck Cancer

Phase 3
Completed
Conditions
Head and Neck Cancer
Interventions
Radiation: standard dose
Radiation: dose de escalation
Registration Number
NCT01812486
Lead Sponsor
Universitaire Ziekenhuizen KU Leuven
Brief Summary

A randomized clinical trial was initiated to investigate whether a reduction of the dose to the elective nodal sites and the swallowing apparatus delivered by IMRT would result in a reduction of acute and late side effects without compromising tumor control.

Detailed Description

1. Study hypothesis

Dose de-escalation in the elective nodal sites and off-target regions of the swallowing apparatus delivered by IMRT does reduce overall rate of late dysphagia and neck fibrosis comparing to the standard dose to the elective nodal sites.

2. Primary endpoint

To estimate the difference in overall rate of late dysphagia and neck fibrosis 1 year after the end of radiotherapy in patients receiving dose de-escalation to the elective nodal sites and off-target regions of the swallowing apparatus applying IMRT.

3. Secondary endpoints

Local, regional and distant control Recurrence and site of recurrence Overall, disease-free and disease-specific survival Acute toxicity Quality of life
