MSCT Manifestations and Quantitative Dynamic Evolution of Lung Cancer Associated with Cystic Airspaces: A Retrospective Analysis of 102 Cases with Emphasis on Adenocarcinoma
By Xiaoqin Luo, Shan Lan and Chengwen Tong.
Abstract
Objective
Cystic lung cancer (CLC) refers to lung cancer associated with cystic airspaces. This study characterized the Multi-Slice Computed Tomography (MSCT) features of CLC, with subtype-specific and longitudinal analyses restricted to adenocarcinoma cases.
Methods
We retrospectively analyzed 102 patients with pathologically confirmed CLC at Renmin Hospital (2018– 2025). Of these, 94 (92.2%) had adenocarcinoma, classified per the IASLC/ATS/ERS system; MSCT features were compared across subtypes using Chi-square tests. The 8 non-adenocarcinoma cases were described separately. A subgroup of 45 patients with serial CT (≥ 3-month interval), all with adenocarcinoma, was assessed for longitudinal changes.
