Staging Strategies and Their Association With Prognosis and Therapy in Lung Cancer With Cystic Airspaces
T-Staging Strategies and Their Prognostic and Therapeutic Significance in Lung Cancer With Cystic Airspaces: A Retrospective Cohort Study
Source: ClinicalTrials.gov · Last updated 4 Sept 2026
Brief summary (registry, in English)
The goal of this observational study is to determine the most accurate tumor size measurement method for T-staging and prognostic assessment in lung cancer with cystic airspaces (LCCA). The main questions it aims to answer are: * What is the optimal T-staging approach for accurately classifying lung cancer with cystic airspaces （LCCA) and predicting patient outcomes? * How do imaging features of cystic lesions correlate with their pathological characteristics? * What is the relationship between imaging features of cystic airspace-associated lesions and patient prognosis? * Can optimizing the T-staging method improve clinical decision-making in patients with LCCA?

Who cannot take part
Copied verbatim from ClinicalTrials.gov and grouped by topic. Only the trial team decides who can take part.
Prior treatment
- Systemic anti-tumor therapies, including chemotherapy, radiotherapy, or targeted therapies (such as monoclonal antibodies, small-molecule tyrosine kinase inhibitors, among others), were administered prior to enrollment;
- Patients with concurrent other malignancies;
Other illness
- History of pulmonary diseases that could produce cystic lung lesions (e.g., tuberculosis, pulmonary fungal infections, bullae, emphysema, Lymphangioleiomyomatosis \[LAM\], or Birt-Hogg-Dubé \[BHD\] syndrome);
Other
- Patients with missing or poor-quality preoperative chest CT imaging data.
Who the study is looking for
- Histologically confirmed non-small cell lung cancer (NSCLC), as verified by biopsy or postoperative pathological examination;
- Patients who have undergone surgical lung resection;
- Patients with complete preoperative chest CT imaging data;
- Preoperative chest CT showing a well-defined gas-containing (air-filled) cystic component within the tumor.
