Development and validation of a machine learning model to predict early recurrence after surgery in NSCLC patients
This multicenter cohort study developed and validated a machine learning (ML) model to predict early recurrence (ER) within two years post-surgery in non-small cell lung cancer (NSCLC) patients. Utilizing data from 3,171 NSCLC patients and nine ML algorithms combined with a stacking method, the model achieved superior predictive performance (AUC=0.81, accuracy=0.83). Key predictors included pathological T and N stages, tumor differentiation grade, maximum tumor diameter, and tumor markers. An online computing platform is available to aid personalized treatment and follow-up strategies, offering a valuable tool for clinicians.
Executive Impact: Revolutionizing NSCLC Recurrence Prediction
Early recurrence after NSCLC surgery poses a significant challenge, impacting survival rates and quality of life. This AI-driven predictive model offers a crucial advancement by accurately identifying high-risk patients early. By leveraging readily available clinical data and sophisticated machine learning, enterprises in healthcare can enhance patient stratification, optimize treatment pathways, and reduce long-term care costs associated with recurrence. The model's interpretability and online accessibility provide a powerful tool for integrating precision medicine into oncology, improving patient outcomes and resource allocation.

The stacking ensemble model significantly outperformed individual machine learning algorithms in predicting early recurrence.
pT Stage
identified as a key determinant of early recurrence risk, alongside maximum tumor diameter and tumor markers.
This provides actionable insights for clinicians to focus on specific pathological and tumor characteristics for risk stratification.
77%
of patients with pT3-4 stage experienced ER, compared to 50% for lower stages.
This highlights the strong correlation between advanced primary tumor size/extent and the likelihood of early recurrence, reinforcing its importance in risk assessment.
51%
of patients with pN1-2 stage experienced ER, compared to 31% for pN0 stage.
Advanced nodal involvement significantly increases ER risk, underscoring the importance of lymph node status in prognosis.
68%
of patients with poorly differentiated tumors experienced ER, compared to 54% for better differentiated tumors.
Tumor biology, as reflected by differentiation grade, is a crucial factor influencing recurrence, indicating aggressive disease.
Accessible Clinical Decision Support
An online computing platform (https://nsclc-risk.shinyapps.io/NSCLC_early_recurrence/) has been made publicly available and free-to-use by doctors and patients, enabling personalized treatment decisions and follow-up strategies.
This platform empowers clinicians with real-time, AI-driven risk assessments, integrating directly into existing workflows.
| Site | Proportion of ER Patients |
|---|---|
| Lung | 35.2% |
| Brain | 24.1% |
| Bone | 18.5% |
| Mediastinum | 16.6% |
| Liver | 11.4% |
| Adrenal Glands | 7.2% |
Among patients experiencing early recurrence, specific sites were more frequently observed, informing targeted follow-up strategies.
Guiding Personalized Patient Management
The model, based on readily available clinical data, offers a valuable tool for personalized treatment decisions and follow-up strategies, enabling clinicians to tailor interventions for high-risk patients.
Early identification allows for proactive, tailored interventions, potentially improving survival and quality of life.
Generalizability & Future Studies
The study was constructed based on a Chinese population, and its applicability to other global populations remains uncertain. Future prospective studies across multiple centers are needed to further validate the model's generalizability and accuracy.
Expanding data diversity and conducting prospective validation are crucial next steps for broader clinical adoption.
