Abstract:
Objective To investigate the relationships of neuron-specific enolase (NSE) and progastrin-releasing peptide (ProGRP) with the initial chemotherapeutic effect and survival of patients with small-cell lung cancer (SCLC).Methods A total of 197 patients with SCLC diagnosed pathologically from January 2011 to September 2013 in Shanxi Provincial Cancer Hospital were selected.x 2 test and logistic regression analysis were used to analyze the factors affecting the initial chemotherapeutic response;KaplanMeier method,log-rank test and Cox regression analysis were used to analyze the factors affecting survival of patients.Results Among the 197 patients,NSE was negative in 64 cases and positive in 133 cases;ProGRP was negative in 51 cases and positive in 146 cases;41 cases with hyponatremia and 156 cases without hyponatremia.152 cases (77.2 ％) had well response to initial treatment and 45 cases (22.8 ％) had no reaction.Univariate analysis showed that stage of disease (x2 =4.456,P =0.033) and ProGRP (x2 =13.424,P ＜ 0.001) were associated with initial therapeutic response.Logistic regression analysis showed that stage of disease (OR =0.404,95 ％ CI 0.197-0.828％,P =0.013) and ProGRP (OR =4.058,95 ％ CI 1.939-8.491,P =0.000) were the independent predictors of initial therapeutic response.Kaplan-Meier survival analysis showed that sex,age,smoking,with or without hyponatremia,stage of disease,NSE,ProGRP and number of chemotherapy cycles were all associated with 2-year survival rate (x2 values were 4.319,6.811,4.264,4.687,32.631,41.045,11.379,33.466,respectively,all P ＜ 0.05).Multivariate analysis showed that stage of disease (RR =2.110,95 ％ CI 1.491-2.985,P ＜ 0.001),number of chemotherapy cycles (RR =0.398,95 ％ CI 0.283-0.588,P ＜ 0.001) and NSE (RR =1.422,95 ％ CI 1.113-1.784,P =0.002) were independent predictors of survival.However,ProGRP was not associated with survival of patients (RR =1.065,95 ％ CI 0.854-1.328,P =0.587).Conclusions ProGRP is associated with the initial chemotherapeutic response in patients with SCLC,and it has certain clinical significance in predicting the initial chemotherapeutic effect.NSE is associated with the survival prognosis of SCLC,and it is a prognostic factor of poor survival.
