Molecular Analysis for Gastro-Esophageal Cancer: Multicenter Discrete Choice Experiment (MAGECmultiDiCE)

February 14, 2026 updated by: Stijn Vanstraelen, KU Leuven

The goal of this survey is to investigate the participants' preference for a specific screening/diagnostic tool to detect and assess gastro-esophageal cancer.

The main question it aims to answer are:

  • Which diagnostic modality is preferred by patients and the general population?
  • Which features of the diagnostic test are most detrimental in the decision-making for one or the other modality?
  • Are geographical differences present in regard to the preference for a diagnostic modality?

Participants will be asked to complete a survey of 20-25min, including a brief intake regarding their socio-economic status. This approach will allow us to correct for confounding factors.

What is the study measuring?

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
The rate of contribution of diagnostic features to the preference of participants
Time Frame: 2 years
A part-worth analysis, expressed as percentage, from a discrete choice experiment (questionnaire) will assess the features that are most important to the participants
2 years
The percentage differences in preference of participants between geographical regions
Time Frame: 2 years
Differences in preferences will be compared between different geographical regions using chi-squared or McNemar's test
2 years

Secondary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Assess the rate patient-level demographics influence the importance of a test feature, expressed as an odds ratio
Time Frame: 2 years
Assess the influence of demographic characteristics on the decision-making process using a multivariable logistic regression model, providing odds ratios.
2 years
Assess the rate of trade-off demonstrated as odds ratio between cancer-related mortality reduction and costs
Time Frame: 2 years
Based on an anticipated cancer detection and cost, we will assess the willingness-to-pay using a multivariable logistic regression, providing odds ratios.
2 years
