This questionnaire is an updated of the EORTC QLQ-LC13. The EORTC QLQ-LC13 was the first module developed to be used in conjunction with the core questionnaire C30. Since the publication of the LC13 in 1994, major advances have been made in the treatment of lung cancer as well as in assessing quality of life. Therefore, the EORTC decided to support a project to update the LC13. [1]

The update of the EORTC questionnaire for assessing quality of life in lung cancer follows a rigorous methodology including patient involvement on various levels. The updated questionnaire after Phases 1 to 3 comprises, in addition to the original items, new items related to the side-effects of targeted therapies and surgery. The updated module currently undergoes full validation and psychometric testing in a cross-cultural, multicenter Phase 4 study, involving 19 centers from 12 different countries. The updated module should become the new standard for quality of life assessment in lung cancer clinical trials.

The EORTC-QLQ-LC29 flow contains the EORTC-QLQ-LC29 questionnaire and associated calculation. After form submission, the EORTC-QLQ-LC29 calculation is executed automatically. It's easy to extend this flow with conditional logic based on the interpretation of the EORTC-QLQ-LC29 calculation.
