The EORTC QLQ-C30 is a questionnaire developed to assess the quality of life of cancer patients.
It is a copyrighted instrument, which has been translated and validated in over 100 languages and is used in more than 3,000 studies worldwide. Presently QLQ-C30 Version 3.0 is the most recent version and should be used for all new studies.
It is supplemented by disease-specific modules for e.g. Breast, Lung, Head & Neck, Oesophageal, Ovarian, Gastric, Cervical cancer, Multiple Myeloma, Oesophago-Gastric, Prostate, Colorectal Liver Metastases, Colorectal and Brain cancer which are distributed by the EORTC Quality of Life Department. Other disease specific modules are under development but not yet validated.
We have also developed a Satisfaction with Care measure (EORTC-IN-PATSAT32) and a Palliative Care questionnaire (QLQ-C15-PAL). These are also general questionnaires.
Conditions for the use of questionnaires are dependent on whether they will be employed in an academic or commercial setting. For academic settings, there is no charge, but a User Agreement is required for each study (please go to the 'Academic Only Download' button below to fill in a download request).
The download request on this website is for academic use only.
For studies carried out by a commercial sponsor or if your study is being wholly or partially sponsored (funded, organized, initiated, managed or run) by the pharmaceutical industry, a compensation fee is payable. A compensation fee is required per study. The amount of the fee depends on the number of patients. For further details for commercial use, please contact Christopher Courtois directly.
Thank you for your understanding.
The funds that are generated through the copyright arrangement are used exclusively to support the ongoing research of the QLG on the development and refinement of quality of life instruments.
