67例肺癌ECT全身骨显像及血清Cyfra21-1、NSE、CEA、CA125联合测定分析

Objective To explore the correlation between Cyfra21-1、 NSE、 CEA、CA125 and the bone metastasis in lung cancer.Methods Images were obtained on a gamma camera (E.CAM,Siemens,Erlangen,Germany)using 99mTC-MDP as a skeletal imaging agent.67 cases diagnosed as lung cancer were performed by ECT bone imaging,serum concentration of Cyfra21-1,NSE,CEA and CA125 were measured among 30 healthy individual,33 patients with pulmonary tuberculosis and 67 patients with lung cancer by electrogenerated chemiluminescence(ECL) (Roche,Germany).Results The serum Cyfra21-1、NSE、CEA、CA125 from lung cancer were higher than that of controls group and pulmonary tuberculosis group(P<0.01).and the pleural Cyfra21-l and NSE were significantly higher than that in serum.In lung cancer,there are correlation between tumor marker and its pathological types.Cyfra21-1 concentration in squamous cell carcinoma were significantly higher than that of other lung cancers(P<0.01),NSE level in small cell lung cancer were significantly higher than that other lung cancers(P<0.01).33 patients with lung cancer had no obvious sign of bone metastases among 67 cases (accounting for 49.3%),34 patients had bone metastases with varying degrees(accounting for 50.7 % ) ;Adenocarcinoma has highest incidence of bone metastasis( 64 % ),followed by small cell lung cancer and squamous cell carcinoma.Cyfra21-land NSE level is highest in cases with wide spread bone metastasis,followed by those with part bone metastasis and without bone metastasis in turn.Conclusion There are relationship between tumor marker and bone metastasis of lung cancer.Multiple bone metastases often were accompanied by obvious change of serum tumor marker.Cyfra21-lis a useful tool in diagnosis of non-small cell lung cancer,especially in squamous cell carcinoma.NSE is useful to identify the small cell lung cancer.Combined determination of Cyfra21-1,NSE,CEA and CA125 can improve sensitivity,accuracy and positive rate of diagnosis lung cancer.It seems that the whole body bone imaging combined Cyfra21-1,NSE,CEA and CA125 detection have important clinical value in diagnosis and identification of lung cancer.

Combing analysis the whole body bone imaging and the tumor marker of Cyfra21-1,NSE,CEA and CA125 in 67 patient with lung cancer
