## Summary

The recent development of imaging and sequencing technologies has revolutionized the clinical study of lung cancer. However, the sheer volume of data generated from these technologies poses a challenge for human analysis and utilization. This is where machine learning-based approaches come into play, as they are capable of integrating and analyzing large and complex datasets in a systematic manner. In this article, authors Yawei Li, Xin Wu, Ping Yang, Guoqian Jiang, and Yuan Luo provide an overview of machine learning applications in various aspects of lung cancer diagnosis and therapy. One area where machine learning excels is early detection. By leveraging imaging data, machine learning algorithms can effectively extract nuanced information from suspicious regions in order to identify potential lung nodules. Traditional methods relied on arbitrary feature extractions based on image intensity, shape, and texture along with other clinical variables. However, these approaches may not capture the intrinsic features of a nodule accurately. To address this limitation, a CNN-based CAD system was developed that directly extracts features from raw imaging data using multilevel representations and hierarchical abstraction. This approach allows for objective and comprehensive extraction of intrinsic features. Machine learning also plays a crucial role in auxiliary diagnosis by assisting clinicians in making accurate assessments based on diverse perspectives obtained from accumulated data. By analyzing various types of data such as genomic profiles or gene expression patterns, machine learning algorithms can identify biomarkers or genetic signatures associated with lung cancer subtypes or treatment response. These insights can then be used to guide personalized treatment decisions. Prognosis prediction is another area where machine learning demonstrates its utility. By training models on large datasets containing patient characteristics and outcomes, machine learning algorithms can generate predictive models that help estimate survival rates or disease progression for individual patients. This information can aid clinicians in developing tailored treatment plans based on predicted outcomes. Furthermore, machine learning has shown promise in the field of immunotherapy practice for lung cancer patients. By analyzing genomic data and extracting relevant features using machine learning algorithms, researchers can identify potential immunotherapy targets or predict patient response to specific treatments. This information can guide the development of personalized immunotherapy strategies and improve treatment outcomes. Despite the significant progress made in applying machine learning to lung cancer diagnosis and therapy, there are still challenges that need to be addressed such as effectively extracting nuanced information from imaging data; model interpretability; dataset bias; and clinical implementation challenges related to imaging data analysis,. While traditional methods relied on human-defined features, recent advancements in deep learning such as Convolutional Neural Networks (CNNs) and Vision Transformers (ViTs) allow for more objective and comprehensive feature extraction directly from raw imaging data.. In conclusion, machine learning-based approaches have greatly enhanced our understanding of lung cancer by integrating and analyzing large complex datasets which have proven valuable in early detection; auxiliary diagnosis; prognosis prediction;and immunotherapy practice .
