Abstract:
Objective To study the correlation of the serum levels of pro-gastrin-releasing peptide (ProGRP) and neuro-specific enolase (NSE) with different treatments in limited-disease small cell lung cancer (L-SCLC) patients.Methods 150 L-SCLC patients were randomly divided into three groups including concurrent chemo-radiotherapy group,sequential chemo-radiotherapy group,and chemotherapy group.The serum levels of ProGRP and NSE were detected by enzyme-linked immunosorbent assay (ELISA) and electrochemiluminescence immunoassay before and after different treatments.The follow-up phase was 12 months.Results The serum levels of ProGRP and NSE were significantly decreased in all 3 groups after treatment (318.96,250.77,226.18 pg/ml and 31.72,23.95,17.89 μg/L),and the lowest level was observed in concurrent chemo-radiotherapy group,then the sequential chemo-radiotherapy group and chemotherapy group.The short term therapeutic effects were in the same sequence,and there was statistical significance between concurrent chemoradiotherapy group and chemotherapy (P ＜ 0.05).The decrease extent of ProGRP and NSE in effective cases (CR+PR) was significantly higher than that in failure cases in all 3 groups.The serum levels of ProGRP and NSE were increased with disease progress (P ＜ 0.05).Conclusion The serum levels of ProGRP and NSE can be used to reflect the patient' s condition and evaluate therapeutic effect in L-SCLC.The concurrent chemo-radiotherapy is more effective than sequential chemo-radiotherapy and chemotherapy only in L-SCLC.
