Clinical characteristics and treatment analysis of pulmonary blastoma (PB): a report of 17 cases

Preoperative diagnosis of pulmonary blastoma is challenging, with the biphasic type being the predominant pathological subtype. The advanced stage at the time of diagnosis is a key factor for poor prognosis. There is a significant difference in age between pediatric and adult patients. Tumor stage is a key factor affecting prognosis, and the Ki-67 positivity rate is negatively correlated with survival time. Emphasizing the formulation of treatment strategies based on pathological types and tumor stages can provide a reference for improving the level of diagnosis and treatment.
