PHILUCA: The Development of Muscle Mass, Muscle Strength, and Muscle Function in Patients With Lung Cancer During Cancer Treatment

The PHILUCA prospective cohort study investigates the relationship between sarcopenia, cachexia, and change in muscle parameters with both treatment tolerance, quality of life and survival in patients with lung cancer receiving systemic treatment(s) (n=160). It aims to identify factors associated with difficulties in completing oncological treatment and to elucidate patterns that may inform improved patient support and individualized treatment planning. The study involves non-invasive physical assessments, patient-reported questionnaires, and the analysis of routinely collected medical data.

Assessments of muscle mass, muscle strength, muscle function, and quality of life are conducted at key time points, including at diagnosis and after three months into treatment or until the first control scan. Physical tests are performed during routine hospital visits, requiring no additional appointments. Body composition analysis is performed using Bioelectrical impedance analysis and by Computed Tomography scans obtained as part of standard care, without additional imaging procedures.

All participants receive standard lung cancer treatment, which may include surgery, chemotherapy, radiation therapy, immunotherapy, targeted therapy, or combinations thereof, based on disease type and stage. The study does not interfere with or modify standard care protocols. Participants unwilling or unable to fully participate may still contribute by completing a baseline questionnaire and consenting to the use of medical record data.

The study seeks to advance the understanding of how muscle-related parameters influence cancer treatment outcomes. The findings are anticipated to inform strategies for optimizing treatment tolerance, improving patient outcomes, and tailoring supportive care interventions for individuals with lung cancer.
