LYMPH-Q translation, cultural adaptation and validation in Italian language: A prospective PROMs-based study on breast cancer-related arm lymphedema for patients' education.

Background: Upper Extremity Lymphedema following oncological breast surgery affects not only the patient's physique, but also the patient's psychological sphere. One of the best known PROMs-based questionnaires for investigating the condition is the LYMPH-Q. The study aimed to perform the Italian translation and cultural adaptation of the LYMPH-Q and to assess if, independently from disease evolution, arm sleeve improves QoL in these patients.

Materials And Methods: Translation included 4 steps: Forward translation, Back translation, Back translation review and Patient interviews. The questionnaire was administered to 50 female patients older than 18 years of age with UEL who received a prescription for daily use of a compression sheath. A second administration took place 30 days after. Forty-four patients completed the study (Group 1: 26 patients with indication to use compression sleeve who wore it; Group 2:18 patients who despite the prescription did not want to wear it. A descriptive statistical analysis was performed with Prism 9 software.

Results: T-tests showed statistical significance for changes in "Symptoms," "Function," "Appearance" and "Psychological" scales. There were no statistically significant changes for "Information scale" in Group 1 and for all scales in Group 2.

Conclusion: Data from this observational study show that HR-QOL analyzed from the patients' perspective also tends to improve in terms of symptoms, function, appearance, and psychological sphere in patients with BCRL when using a compression sheath. The Lymph-Q has proven to be a valuable ally of the physician attempting to improve treatment approaches for BCRL based not only on scientific evidence but also on PROMs.
