About this study

The aim of this study is to evaluate the mylohyoid, geniohyoid and digastric muscles in patients with radiotherapy-induced dysphagia due to nasopharynx cancer using ultrasonography and shear wave elastography (SWE).

Read the detailed description

Post-radiotherapy swallowing dysfunction evaluation was carried out using fibreoptic endoscopic evaluation (FEES), ultrasonography of the swallowing muscles, shear wave elastography and swallowing assessment scale between the dates of 01/01/2023 and 01/06/2023.

All patients were interviewed to obtain detailed medical histories. Following this, standardized swallowing assessments were administered, including the Eating Assessment Tool (EAT-10) and the M.D. Anderson Dysphagia Inventory (MDADI). Head and neck examination, endoscopic examination and fibreoptic endoscopic swallowing assessment were performed at the Otorhinolaryngology, Head and Neck Surgery clinic. Penetration Aspiration Score (PAS) was determined by the experienced faculty member. Afterwards, an experienced radiologist performed neck ultrasonography and shear wave elastography (SWE) using an Aplio 500 Platinium Ultrasonography system (Toshiba Medical Systems, Japan) equipped with high-frequency linear transducer (frequency range = 5-14 MHz). With SWE, the stiffness values of the mylohyoid, geniohyoid and digastric muscles were measured in m/s and kPa, and their thickness was measured in mm. The tissue elasticity was outlined using a colour-coded system ranging from dark blue indicating least stiffness to red representing greatest stiffness, with a default measurement range of 0-120 kPa. The elastic value E (kPa) is calculated using the equation E = 3 ρ (m/s) 2. In the equation, m/s represents the shear wave propagation speed, and ρ represents the tissue density (approximately 1 in humans). All patients receiving radiotherapy were treated in our hospital's radiation oncology clinic for Stage I nasopharyngeal cancer received 70 Gy (2,12 Gy/Gun) gross tumour value (CTV70), with 5-10 mm margin for microscopic spread, delivered according to the International Commission on Radiation Units and Measurements (ICRU) Reports 50 and 62 guidelines. After obtaining the data, comparisons between the groups and correlations between the quantitative data were assessed using appropriate statistical methods.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Swallowing muscle thickness

    Right and left digastric - mylohyoid muscle thickness, as well as geniohyoid thickness using ultrasonography and Shear Wave Elastography. The thickness values of the mylohyoid, geniohyoid and digastric muscles were measured in mm by experienced radiologist.

    Measured: 12 months after radiotherapy.

  2. Swallowing muscle pressure

    Right and left digastric - mylohyoid muscle pressure, as well as geniohyoid pressure using ultrasonography and Shear Wave Elastography. The outcome pressure is measured in kPA by an experienced radiologist .

    Measured: 12 months after radiotherapy.

  3. Swallowing muscle velocity

    Right and left digastric - mylohyoid muscle velocity, as well as geniohyoid velocity using ultrasonography and Shear Wave Elastography. The velocity values of the mylohyoid, geniohyoid and digastric muscles were measured in m/s by an experienced radiologist.

    Measured: 12 months after radiotherapy.

Questions about this trial

What is this clinical trial studying?

An observational study of Patients Receiving Radiotherapy for Nasopharyngeal Carcinoma Diagnosis and Ultrasonography and Shear Wave Elastography, run by Konya Beyhekim Training and Research Hospital at 1 site in Turkey (Türkiye).

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 19 inclusion and 5 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 18 Apr 2025. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Turkey (Türkiye). Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Swallowing muscle thickness (time frame: 12 months after radiotherapy.). The study lists 3 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 18 Apr 2025.
