To review the definition, underlying mechanisms, and clinical aspects of noninvasive imaging in the diagnosis, classification, invasiveness prediction, staging, and prognosis assessment of Lung Cancer with Cystic Airspaces (LCCA).
Key Findings:
LCCA accounts for approximately 1–4% of lung cancer cases, predominantly adenocarcinoma.
LCCA is characterized by significant heterogeneity and a relatively poor 5-year survival rate.
The detection rate of LCCA is increasing due to the implementation of low-dose computed tomography (LDCT) in lung cancer screening.
Imaging features of LCCA often overlap with benign conditions, complicating diagnosis.
Current diagnostic guidelines lack standardized protocols for managing LCCA.
Interpretation:
The article discusses the challenges in diagnosing and managing LCCA due to its unique characteristics.
Limitations:
Current research is limited by small sample sizes and predominantly retrospective study designs.
LCCA has not been incorporated into most lung nodule management guidelines.
Conclusion:
The review aims to provide a comprehensive overview of diagnostic and prognostic factors related to LCCA.
Lung cancer resulted in 1.8 million deaths globally in 2022 and remains the leading cause of cancer-related mortality worldwide. Low-dose CT screening has been shown to reduce lung cancer mortality, a...
