A Study Developing a Non-invasive Urine-based Proteomic Model for Early Lung Cancer Detection.

Brief Summary: The goal of this observational study is to develop a non-invasive urine proteomic diagnostic model to improve early-stage lung cancer detection. The study aims to answer the following main questions: Can urine proteomics reliably differentiate early-stage lung cancer from benign conditions? How does the diagnostic model compare to current clinical and imaging methods in accuracy? Participants will: Provide preoperative urine samples. Undergo proteomic analysis of urine samples. Have clinical, imaging, and proteomic data integrated into an AI-assisted diagnostic model. The study will evaluate the sensitivity and specificity of this innovative diagnostic approach.
