Study summary

Background: The aim of this study is to develop a prediction model for radiation-induced trismus (maximal interincisal distance equal to or less than 35 mm) based on a multivariable analysis of dosimetric and clinical factors.

Read the detailed description

The maximum inter-incisal opening (MIO) of hean and neck cancer (HNC) patients who undergo radiotherapy (RT) ± concurrent chemotherapy with radical intent, will be prospectively measured prior to RT (baseline) and 6 months post-RT.

The potential risk factors (clinical and dosimetric) will be first screened by univariate analysis and then by multivariate analysis. At the end of this process, the features identified as relevant, will be used to fit a logistic regression model and calculate the probability of observed trismus during the 6-month follow-up after RT

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Mar 21, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
