Enterprise AI Analysis
A Thorough Review of the Clinical Applications of Artificial Intelligence in Lung Cancer
According to data from the World Health Organization (WHO), lung cancer is becoming a global epidemic. It is particularly high in the list of the leading causes of death not only in developed countries, but also worldwide; furthermore, it holds the leading place in terms of cancer-related mortality. Nevertheless, many breakthroughs have been made the last two decades regarding its management, with one of the most prominent being the implementation of artificial intelligence (AI) in various aspects of disease management. We included 473 papers in this thorough review, most of which have been published during the last 5–10 years, in order to describe these breakthroughs. In screening programs, AI is capable of not only detecting suspicious lung nodules in different imaging modalities—such as chest X-rays, computed tomography (CT), and positron emission tomography (PET) scans—but also discriminating between benign and malignant nodules as well, with success rates comparable to or even better than those of experienced radiologists. Furthermore, AI seems to be able to recognize biomarkers that appear in patients who may develop lung cancer, even years before this event. Moreover, it can also assist pathologists and cytologists in recognizing the type of lung tumor, as well as specific histologic or genetic markers that play a key role in treating the disease. Finally, in the treatment field, AI can guide in the development of personalized options for lung cancer patients, possibly improving their prognosis.

Epidemiology
AI models are being increasingly used in epidemiology for lung cancer to identify high-risk populations for prevention and screening. They leverage extensive datasets including smoking history, age, gender, and other medical conditions (COPD, osteoporosis) to predict cancer development years in advance. This allows for targeted screening interventions and more efficient resource allocation, potentially reducing the global burden of lung cancer by focusing on early detection and cessation programs.
Clinical Features
AI plays a crucial role in analyzing various clinical features, such as cough, hemoptysis, chest pain, and weight loss, alongside demographic data like age, gender, and smoking status, to improve lung cancer diagnosis and prognosis. By processing vast amounts of information from electronic medical records, AI can identify patterns indicative of early-stage disease, predict specific characteristics like EGFR mutations or ALK rearrangements, and assess the tumor immune microenvironment (PD-L1, CD8 expression). This aids in personalizing treatment decisions and improving patient outcomes.
Diagnosis
AI has revolutionized lung cancer diagnosis across various imaging modalities. For X-rays, AI can detect suspicious nodules, enhance ventilation calculations, and suppress bone images for clearer views. In chest CT, AI performs automated nodule detection, discriminates between benign and malignant nodules, categorizes tumor histology and molecular markers (EGFR, ALK), and aids in staging and treatment planning, often with higher accuracy and speed than human radiologists. Similarly, in PET/CT, AI enhances nodule detection, malignancy discrimination, and staging, allowing for earlier and more precise diagnoses, even at ultra-low radiation doses.
Treatment
AI has significantly advanced lung cancer treatment by enabling precise, personalized strategies across surgery, radiotherapy, chemotherapy, targeted therapy, and immunotherapy. In surgery, AI helps identify high-risk patients, recognizes anatomical structures for minimally invasive procedures (robotic surgery), and predicts post-surgical complications. For radiotherapy, AI assists in auto-segmentation of organs-at-risk, treatment planning, and prediction of adverse events like pneumonitis. In targeted therapy, AI predicts EGFR, ALK, and KRAS mutation statuses from imaging and cytological data, guiding TKI selection. In immunotherapy, AI defines immune phenotypes, predicts PD-L1 expression, and identifies optimal treatment combinations, leading to improved patient outcomes and reduced toxicity.
Prognosis
AI models significantly enhance lung cancer prognosis across screening, clinical, imaging, and biomarker data. Early diagnosis through AI-assisted LDCT screening improves overall survival rates. AI integrates clinical features (age, sex, smoking), body composition, and tumor characteristics to predict all-cause mortality and disease-specific outcomes. Radiomic features from CT and PET scans predict invasiveness, recurrence, and response to therapies (TKIs, immunotherapy). Molecular biomarkers like microRNA and lncRNA, detected by AI, predict long-term outcomes and treatment efficacy, providing a comprehensive prognostic assessment for personalized patient management.

Case Study: AI-Driven Personalized Treatment for NSCLC
How AI is revolutionizing personalized treatment options based on patient-specific molecular and immunological profiles.
Description: A 65-year-old male with Stage III NSCLC presented with resistance to standard chemotherapy. AI analysis was deployed to identify alternative treatment pathways.
Challenge: Traditional methods failed to identify effective treatment due to complex genetic and immunological markers.
Solution: AI analyzed comprehensive radiogenomic and liquid biopsy data, predicting an optimal response to a novel targeted therapy and immunotherapy combination.
Impact: The patient achieved significant progression-free survival, exceeding predictions from traditional clinical pathways. AI’s ability to integrate diverse data streams led to a highly individualized and effective treatment plan, improving prognosis and quality of life.
