||Permission is required for all use. Conditions of use depend on whether the use is academic or commercial. Academic use is free but requires an individual agreement. There is a charge for commercial use which is dependent on the number of patients in the study. For academic use, the tool can be accessed via an online form at http://groups.eortc.be/qol/eortc-qlq-c30. After submitting the form you will be sent an email with instructions for downloading the documents. The lung module (LC13) must be used in conjunction with QLQ-C30. It should not be used alone.
