Research progress of urinary volatile organic compounds as diagnostic biomarkers for lung cancer

Lung cancer is one of the most common malignant tumors in the world, and early diagnosis is crucial to the treatment and prognosis of patients. In recent years, researchers in metabolomigcs have increasingly focused on volatile organic compounds in urine as potential diagnostic markers for lung cancer. The purpose of this review is to summarize the research progress of detecting volatile organic compounds in urine as a diagnostic marker for lung cancer in recent years, and to explore its potential application prospects.
