Changes in the urine proteome in patients with advanced lung cancer after different drug treatments

Abstract

Lung cancer is one of the most threatening diseases to human life and health because of its mortality. How to choose more efficient drugs and the appropriate timing of treatment for patients with advanced lung cancer is still a problem. As the urine proteome can sensitively reflect the pathological or physiological changes of the body, it has the potential to reflect the dynamic changes of the body after drug treatment. To investigate the changes in the urine proteome of patients with advanced lung cancer after different drug treatments, urine samples were collected and analyzed at different time points. The changes in the urine proteome from the pretreatment state were different in each patient and the changes in the biological processes were consistent with the changes in the clinical manifestations of the patients. This study demonstrates that the pathophysiological changes of patients with advanced lung cancer can be reflected by changes in urinary protein after different drug treatments. In addition, the changes in urinary proteins can reflect the different biological processes in patients after the same drug treatment, and the patients’ clinical condition assessment results are consistent with these changes. These findings may provide additional information for clinical treatment.
