Brief summary
This prospective observational study aims to evaluate symptom burden and symptom clusters among lung cancer patients undergoing definitive concurrent chemoradiotherapy (CRT), based on electronic patient-reported outcomes (ePROs). Patients will complete the validated MDASI-LC and EQ-5D instruments weekly from baseline through the end of CRT and for 12 weeks post-treatment. The study will characterize the longitudinal trajectories of symptom severity and interference, identify distinct symptom clusters and their temporal patterns, and explore patient-level predictors of symptom burden. The findings may support the development of personalized symptom management strategies and improve quality of life during and after CRT.
Interventions
Participants complete the MDASI-LC and EQ-5D questionnaires electronically on a weekly basis during CRT and for 12 weeks after CRT. The data are used to evaluate symptom burden, symptom clusters, and symptom trajectories.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Longitudinal trajectory of symptom burden over time based on M. D. Anderson Symptom Inventory-Lung Cancer | Baseline, weekly during CRT (weeks 1-6), and weekly for 12 weeks after CRT. | M. D. Anderson Symptom Inventory-Lung Cancer:Scale range 0-10, with higher scores indicating worse symptom burden. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Questionnaire response rate | From baseline to 12 weeks post-CRT | The response rate of the M. D. Anderson Symptom Inventory-Lung Cancer( MDASI-LC) questionnaire will be assessed weekly during chemoradiotherapy (CRT) and up to 12 weeks post-CRT. This measure will reflect the percentage of patients who completed the MDASI-LC questionnaire each week, with higher response rates indicating better engagement and data quality. |
| Trajectory of symptom interference over time based on M. D. Anderson Symptom Inventory-Lung Cancer | From baseline to 12 weeks post-CRT | M. D. Anderson Symptom Inventory-Lung Cancer: scale range 0-10, with higher scores indicating worse interference |
| Change of Quality of life over time | From baseline to 12 weeks post-CRT | Quality of life will be assessed using the EuroQoL-5 Dimension Health Outcome Survey (EQ-5D) Questionnaire, a widely used instrument for measuring general health status. The EQ-5D includes five dimensions: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The change in scores will be evaluated from baseline to 12 weeks after completion of chemoradiotherapy . Higher scores on the EQ-5D reflect better quality of life. |
