Is the consolidation-to-tumor ratio an independent prognostic factor in clinical T1 stage lung adenocarcinoma radiologically manifesting as a subsolid nodule?—a retrospective cohort study

Key Points

• The consolidation-to-tumor ratio shows a poorer prognosis when above 0.25, but is not an independent prognostic factor.
• Key evidence reveals that preoperative CEA levels are more stable predictors than CTR, MCD, and MTD.
• Analysis of prognostic factors focused on T1 stage lung adenocarcinoma, particularly subsolid nodules.
• These findings highlight the importance of using CEA levels for prognosis in lung adenocarcinoma assessments.
