Evaluation of quality of life in lung cancer patients receiving radiation and Viscum album L.: a real-world data study

Radiat Oncol. 2023 Mar 6;18(1):47. doi: 10.1186/s13014-023-02234-3.

Abstract

Background: Lung cancer (LC) is associated with high mortality and poor quality of life (QoL). The disease as well as oncological treatments such as radiation and chemotherapy with adverse effects can impair the QoL of patients. Add-on treatment with extracts of Viscum album L. (white-berry European mistletoe, VA) has been shown to be feasible and safe and to improve the QoL of cancer patients. The aim of this study was to analyze the changes in QoL of LC patients being treated with radiation according to oncological guidelines and add-on VA treatment in a real-world setting.

Methods: A real-world data study was conducted using registry data. Self-reported QoL was assessed by the evaluation of the European Organization of Research and Treatment Health-Related Quality of Life Core Questionnaire scale (EORTC QLQ-C30). Adjusted multivariate linear regression analyses were performed to analyze factors associated with changes in QoL at 12 months.

Results: A total of 112 primary LC patients (all stages, 92% non-small-cell lung cancer, median age 70 (ICR: 63-75)), answered the questionnaires at first diagnosis and 12 months later. Assessment of 12 months changes in QoL revealed significant improvement of 27 points for pain (p = 0.006) and 17 points for nausea/vomiting (p = 0.005) in patients who received combined radiation and VA. In addition, significant improvements of 15 to 21 points for role (p = 0.03), physical (p = 0.02), cognitive (p = 0.04), and social functioning (p = 0.04) were observed in guideline treated patients receiving no radiation but add-on VA.

Conclusions: Add-on VA therapy reveals supportive effects for the QoL of LC patients. Particularly in combination with radiation a significant reduction in pain and nausea/ vomiting has been observed. Trial registration The study received ethics approval and was retrospectively registered (DRKS00013335 on 27/11/2017).
