impact of psychological stress on treatment response and prognosis in lung cancer patients

Conditions: Cancer of Lung; Depression Disorders; Anxiety Disorder/Anxiety State

Summary: this study explores how psychological stress may influence the treatment response and long-term outcomes in patients with lung cancer. while advances in surgery, chemotherapy, immunotherapy, and targeted therapies have improved survival, emotional well-being remains an often-overlooked factor. we aim to investigate whether high levels of stress, anxiety, or depression at the time of diagnosis or during treatment are linked to poorer responses to therapy or shorter survival. by identifying these associations, the study hopes to highlight the importance of psychological care as part of comprehensive cancer treatment. the findings may inform future strategies to integrate mental health support into routine care for patients with both early-stage and advanced lung cancer.
