A clinicopathological study of lung adenocarcinomas with pure ground-glass opacity & gt; 3 cm on high-resolution computed tomography

ConclusionsThis study demonstrated that PGGMs> 3 cm could still be AIS-MIAs. When PGGMs are encountered in clinical practice, the CT value may be the only valuable parameter to preoperatively distinguish IACs from AIS-MIAs.Key Points• Patients with pure ground-glass opacity> 3 cm in diameter are rare but can be diagnosed as adenocarcinomas in situ or minimally invasive adenocarcinomas.• The mean CT attenuation is the sole significant CT parameter that differentiates invasive adenocarcinoma from adenocarcinoma in situ or minimally invasive adenocarcinoma in patients with pure ground-glass opacity> 3 cm.• Lung adenocarcinoma with pure ground-glass opacity> 3 cm has an excellent prognosis, even in cases of invasive adenocarcinoma.
