RESUMEN
Objective To study the relationship of serum pulmonary surfactant protein and vascular endothelial growth factor re‐lated indexes to lung cancer .Methods Totally 56 patients with lung cancer in our hospital from September 2014 to December 2015 were selected as the observation group ,56 healthy personnel at the same period were selected as the control group ,then the serum pulmonary surfactant protein and vascular endothelial growth factor related indexes of control group and observation group ,obser‐vation group with different stages and pathological classifications were compared ,and the relationship between serum pulmonary surfactant protein and vascular endothelial growth factor related indexes and lung cancer were satisfacted with Logistic analysis .Re‐sults The serum pulmonary surfactant protein and vascular endothelial growth factor related indexes of observation group were all higher than those of control group ,and the serum pulmonary surfactant protein and vascular endothelial grow th factor related inde‐xes of observation group with higher stages were all higher than those of patients with lower stages ,and the levels of patients with adenocarcinoma were all higher than those of patients with squamous cell carcinoma ,and the serum pulmonary surfactant protein and vascular endothelial growth factor related indexes all had close relationship to the lung cancer (all P<0 .05) .Conclusion The serum pulmonary surfactant protein and vascular endothelial growth factor related indexes all have close relationship to the lung cancer ,and those indexes of patients with lung cancer should be paid more attention .
