Moon Y, et al. - This study entails the analysis of the histopathologic features of invasive adenocarcinoma presenting as ground-glass opacity (GGO) on chest computed tomography (CT) and the prognosis after sublobar resection. Findings indicated that on chest CT, invasive components such as acinar and papillary components can also be seen as GGO tumours. Notably, sublobar resection of GGO-predominant tumours can afford a good prognosis, even if the tumour is an invasive adenocarcinoma such as the acinar or papillary subtypes.
