[Clinical significance of multiple tumor marker protein chip in monitoring the recurrence,progression and metastasis of lung cancer].
BACKGROUND
According to the report of the 11th World Conference on Lung Cancer, lung cancer is the leading cause of cancer related death. So there is important clinical significance to monitor the patients with lung cancer through different ways. The aim of this study is to investigate the clinical significance of multiple tumor marker protein chip in monitoring the recurrence, progression and metastasis of lung cancer.


METHODS
Forty-four patients were selected, who were detected at least 4 times with tumor mar-ker protein chip. Based on efficacy and status, patients were classified as six grades. Correlation of expression level of each tumor marker with grade of efficacy and status was analyzed. And the discriminant functions for recurrence, progression and metastasis of lung cancer were established.


RESULTS
Grade of efficacy and status was closely related to CA199, CEA, CA242, AFP and CA125 in adenocarcinoma (AC), to CA125 in squamous cell carcinoma (SqCa), and to CA199 and CA125 in small cell lung cancer (SCLC). Based on the discriminant functions, accuracy rate of efficacy and status judgement was 89.4%, 80.4%, 78.3% and 66.7% for female AC, male AC, SqCa and SCLC respectively.


CONCLUSIONS
There is important clinical significance of multiple tumor marker protein chip in monitoring the recurrence, progression and metastasis of lung cancer (especially adenocarcinoma).
