What this trial studies

This observational study aims to evaluate the potential of the serum marker LncRNA RP5-977B1 in distinguishing between benign and malignant pulmonary nodules identified through imaging. It will involve collecting leftover blood samples from patients who have undergone surgery for pulmonary nodules, with a focus on constructing diagnostic models that combine this marker with clinical protein tumor markers. The study will assess the sensitivity and specificity of these markers based on pathological results, providing new insights into the diagnosis of lung tumors.

Who should consider this trial

Good fit: Ideal candidates are patients aged 15-75 with pulmonary nodules detected by imaging who are scheduled for surgical resection.

Not a fit: Patients with a history of malignant tumors or serious underlying diseases may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to improved diagnostic accuracy for patients with pulmonary nodules, potentially reducing unnecessary surgeries.

How similar studies have performed: While the approach of using serum markers for diagnosis is established, the specific use of LncRNA RP5-977B1 in this context is novel and has not been extensively tested.
