【Abstract】 Objective To investigate the ex pr ession of squamous cell carcinoma antigen (SCC-Ag) and carcinoembryanic antigen (CEA) and its clinical significance in patients with lung cancer. Meth ods The pre-treatment serum from 134 patients with lung cancer from 1998 to 2002 were analyzed for the SCC-Ag level and CEA level by IMX, and the correlation of the SCC-Ag level and CEA level with the clinicopathologic charac teristics were also detected. Results Significant correlations were found between the pre -treatment SCC-Ag level, and CEA level and the pathologic classification, clin ical stage, the positive rate of diagnosing lung cancer was raised by combined a ssay with serum SCC-Ag and CEA. Conclusion Pre-treatment and after-treatment measurement of serum SCC-Ag level and CEA level can be used for diagnosis, prediction of pr ognosis and monitor of after-treatment recurrence in patients with lung cancer.更多还原
