The main questions it aims to answer are:\n\n* What is the optimal T-staging approach for accurately classifying lung cancer with cystic airspaces （LCCA) and predicting patient outcomes?\n* How do imaging features of cystic lesions correlate with their pathological characteristics?\n* What is the relationship between imaging features of cystic airspace-associated lesions and patient prognosis?\n* Can optimizing the T-staging method improve clinical decision-making in patients with LCCA?",[62],"Lung Cancer Associated With Cystic Airspaces","2026-03-16",{"date":65,"type":66},"2026-03-18","ACTUAL",{"date":68,"type":66},"2025-06-01",{"date":70,"type":58},"2026-07-01",{"name":5,"class":6},1]
