Predicting blood clots after lung cancer surgery

Prospective Cohort Study on Risk Factors and Machine Learning-Based Prediction of Postoperative Venous Thromboembolism in Patients Undergoing Lung Cancer Surgery

Observational The First Hospital of Jilin University · NCT07439991

This project will try to use clinical, surgical, and lab data to predict which adults having lung cancer surgery may develop blood clots after the operation.

What this trial studies

This observational study will follow adults undergoing surgical resection for lung cancer for 30 days after surgery to record perioperative clinical, laboratory, and imaging data. Investigators will identify clinical and surgical risk factors associated with postoperative deep vein thrombosis (DVT) and venous thromboembolism (VTE). Collected data will be used to train and test machine learning models to predict individual patient risk of postoperative VTE. Patients with pre-existing DVT/PE, prolonged anticoagulation, major concurrent surgeries, or severe organ dysfunction will be excluded and no investigational treatments are administered.

Who should consider this trial

Good fit: Adults (age ≥18) who are having surgical resection for lung cancer, will remain hospitalized at least 48 hours after surgery, and can provide informed consent and 30-day follow-up data.

Not a fit: Patients with preoperative DVT or PE, those on prolonged anticoagulation, with severe coagulation or organ dysfunction, or who cannot complete follow-up are unlikely to benefit from this observational prediction project.

Why it matters

Potential benefit: If successful, a predictive model could help doctors identify high-risk patients and target preventive measures to reduce postoperative blood clots.

How similar studies have performed: Previous studies have identified traditional risk factors and risk scores for postoperative VTE, but applying machine learning specifically to predict individual risk after lung cancer surgery is relatively novel.
