Clinicopathological characteristics associated with intrapulmonary metastasis rather than single primary lung cancer at first diagnosis: a study based on the Surveillance, Epidemiology, and End Results database using Bayesian networks and structural equation modeling

Puntos clave

• Intrapulmonary metastasis is linked more closely to tumor differentiation than to sociodemographic factors.
• The study indicates that anatomical distribution and laterality significantly correspond with metastatic disease.
• Analysis utilized structural equation modeling and Bayesian networks on a comprehensive registry dataset.
• The findings suggest better identification of patients with extensive intrapulmonary disease, enhancing clinical strategies.
