• Registration Number: NCT04270123
• Lead Sponsor: University of Leeds

Brief Summary

Female breast cancer is still the most frequent type of cancer in Europe with 21 per 100,000 women .The EORTC QLQ-BR23 was one of the first modules developed to be used in conjunction with the core questionnaire EORTC QLQ-C30 and was published in 1996. Since the beginning of the work on the EORTC QLQ-BR23 some 20 years ago, much knowledge has been gathered about the epidemiology of breast cancer, and major advances have been made with regard to diagnostic and therapeutic options. Therefore, the EORTC Quality of life group decided to update the BC23. A phase 1 to 3 module development project has been completed. This resulted in a 45 item module, retaining 23 of the original items and adding 22 new items, particularly tapping into the side effects of new systemic and local therapies.

The aim of the Phase 4 study is to test the scale structure, reliability, responsiveness to change, and validity of the EORTC QLQ-BC45 in conjunction with the EORTC QLQ-C30 in patients diagnosed with breast cancer. Participants will be enrolled in four groups according to their disease stage (1. local/locally advanced disease, 2. metastatic disease, 3. follow up. Various combinations of therapies are permissible.

According to sample size calculations, we will include a total of N =490 patients from 12 countries.

Participants will be invited to complete the QLQ-C30 and the QLQ-BC45, followed by the Debriefing Questionnaire. Data of all patients will be used to evaluate the scale structure, internal consistency, convergent and discriminant validity. A subgroup of follow up patients with no evidence of disease (no change in health status) will be invited to complete the QLQ-C30 and the QLQ-BC45 for a second time one to two weeks later for the test-retest analysis. A subgroup of patients from the local/ locally advanced breast cancer group (who have had change in disease or treatment status after the first assessment) will be invited to complete a second set of questionnaires for the response to change analysis. Sociodemographic and clinical data will be recorded using standardized case report forms (CRF).

Arm && Interventions

Group	Intervention	Description
Group 3 - follow up	EORTC QLQ-BR45 questionnaire	Group 3 consists of follow up breast cancer patients. All participants will complete the EORTC QLQ-C30 and BR-45 questionnaires. One-to two weeks later, a subgroup of participants in this group (with no evidence of disease and /or change in health status) will complete the above questionnaires, as well as an anchor question. Completing twice is for the test-retest analysis.
Group 1	EORTC QLQ-BR45 questionnaire	Group 1 consists of breast cancer patients with local or locally advanced disease. All participants will complete the EORTC QLQ-C30 and BR-45 questionnaires. A subgroup of participants within this group (those who have changed disease or treatment status) will be asked to complete the above questionnaires again, three months later (+-1 week). They will also complete an anchor question. Completing twice is for the responsiveness to change analysis.
Group 2	EORTC QLQ-BR45 questionnaire	Group 2 consists of metastatic breast cancer patients. All participants will complete the EORTC QLQ-C30 and BR-45 questionnaires at one time point only.
