• Lung cancer (LC) is a leading cause of cancer-related mortality, with smoking being a major risk factor. Despite the benefits of smoking cessation, many LC patients continue to smoke, potentially impacting their quality of life (QoL). This study aimed to explore factors influencing QoL among LC patients, with a focus on smoking status and mental health. A cross-sectional study was conducted at the University Hospital of Augsburg from December 2021 to December 2023. A total of 56 LC patients were categorized into active smokers (AS), ex-smokers (ES), or never-smokers (NS). Participants completed validated questionnaires assessing QoL, depression, anxiety, stress, borderline personality disorder symptoms, and pain. Statistical analyses, including one-way ANOVA and Pearson’s correlation, were employed to examine group differences and the relationship between QoL and mental health factors. No significant differences in overall QoL were observed among AS, ES, and NS. However, mentalLung cancer (LC) is a leading cause of cancer-related mortality, with smoking being a major risk factor.

Statistical analyses, including one-way ANOVA and Pearson’s correlation, were employed to examine group differences and the relationship between QoL and mental health factors. No significant differences in overall QoL were observed among AS, ES, and NS. However, mental health indicators—including depression, anxiety, stress, and borderline personality disorder symptoms—were significantly negatively correlated with QoL across all groups. Pain was also a key factor affecting QoL. These findings suggest that while smoking cessation is critical for improving prognosis in LC patients, mental health and pain management are more pivotal in determining QoL. This study emphasizes the need for a holistic approach to LC patient care, addressing both physical and mental health. Future research should focus on longitudinal studies to better understand the long-term effects of smoking and other influencing factors on QoL in this patient population.…
