Development and Application of Molecular Evaluation Instrument for Lung Cancer Diagnosis and Treatment

The precise diagnosis and treatment of lung cancer is not only a major national strategic need but also an urgent demand from the general public. The "three stages" of precise diagnosis and treatment of lung cancer include early diagnosis, effective treatment, and precise evaluation. Currently, invasive methods are mainly used in these three stages of clinical practice. The non-invasive molecular diagnosis of early-stage lung cancer and the molecular evaluation of treatment efficacy are critical core issues in lung cancer clinical diagnosis and treatment. In response to this problem, this project aims to use exhaled breath as a sample to develop a scientific instrument with independent intellectual property rights, which integrates early-stage diagnosis of lung cancer and evaluation of treatment efficacy. We will also conduct related application research to meet the needs of the public and contribute to the health of the entire population.
