What does this research mean for the field?

Pathological subtypes of lung adenocarcinoma exhibit distinct clinical and biological profiles, with the lepidic subtype showing higher EGFR mutation rates and better survival, whereas the solid subtype is associated with higher PD-L1 expression and poorer survival. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

To clarify the clinical and biological characteristics of lung adenocarcinoma subtypes.
Retrospective analysis of 1412 lung adenocarcinoma cases with complete resection between 2004 and 2023.
Comparison of clinical and biological characteristics based on predominant pathological subtypes.
Assessment of driver mutations and PD-L1 expressions in each subtype.
Lepidic subtype shows higher frequency of EGFR mutations (63.4%) compared to others.
Solid subtype has higher PD-L1 expression (66.6%) but fewer EGFR mutations (12.6%).
5-year recurrence-free survival rates vary by subtype: lepidic (88.2%), acinar (72.9%), papillary (65.1%), solid (58.2%).
