How screening patterns relate to early-stage lung cancer in newly diagnosed patients

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This observational study analyzes real-world data from patients with newly diagnosed primary lung cancer to describe epidemiology and disease spectrum, including age, gender, smoking history, and pathology. It compares screening patterns—overscreening, underscreening, guideline-concordant, and precision screening—to see how they affect the likelihood of detecting cancer in the curative time window (AIS/MIA or pure GGNs) and to estimate related costs and radiation exposure. The goal is to evaluate whether a low-age, low-frequency screening approach could improve early-stage capture. The analysis relies on retrospective or contemporaneous patient information and pathology data captured before or around diagnosis.

Why it matters

Who can join: the full rules

Inclusion Criteria:

* Histologically confirmed primary lung cancer within the past year (surgical or biopsy pathology).
* Patients capable of clearly recalling or providing medical and physical examination history prior to diagnosis.

Exclusion Criteria:

* Recurrent lung cancer or metastatic lung tumors.
* Severe lack of critical clinical data (e.g., inability to provide pathological type or stage).
* Patients with cognitive impairment or severe mental illness who cannot cooperate with the questionnaire.
