Utility Weights for QLU-C10D

To make the QLQ-C30 applicable for health economic evaluations, a cancer-specific utility instrument based on ten dimensions of the QLQ-C30, the QLU-C10D, was developed. This present project, a continuation of the first QLU-C10D valuation project, aims to make EORTC QLQ-C30 data applicable for health economic evaluations in five further European countries and one Asian country. We are collecting data on how people from different countries value aspects of quality of life and which domains are particularly important to them. This is done by calculating country-specific utility weights using the EORTC QLU-C10D. A secondary objective of the project is to investigate the methodological robustness of utility weights. As of July 2025, the project is successfully closed.

The valuation studies in all countries (Sweden, Norway, Hungary, South Korea, Belgium, and Portugal) have been completed and manuscripts have been published or submitted.

A summary of the completed valuation studies across all QLU/MAUCa projects is shown in Figure 1.

Figure note. Countries for which EORTC QLU-C10D value sets have been published in peer-reviewed journals (as of March 2025): Australia, Austria, Canada, China, Denmark, France, Germany, Hong Kong, Italy, Japan, Norway, Poland, Spain, Sweden, The Netherlands, United Kingdom, United States.

Further, the country-specific value sets for the following countries have been developed: Belgium, Hungary, Portugal, South Korea.

This study is now completed.

We are collecting data on how people from different countries value aspects of quality of life and which of these are particularly important to them. It is important to do this for individual countries separately, as people’s preferences differ between countries.

This project is a continuation of our first QLU-C10D valuation project. The QLU-C10D is required for health-economic evaluations using the QLQ-C30. The first EORTC project covered five European countries. The new project extends the old one by establishing the required “utility weights” for a further six countries, five European and one Asian country: Sweden, Norway, Belgium, Portugal, Hungary, and South Korea. This project has now been successfully completed.
