Objective: To observe the effect of combination of Syndrome Differentiation (SD) depending treatment and chemotherapy on prognostic factors in patients with non-small cell lung cancer (NSCLC).
Methods: One hundred and twenty patients with NSCLC were randomly divided into the TCM group, the western medicine (WM) group and the combined TCM and WM (TCM-WM) group. Besides the conventional supporting and symptomatic treatment given to all the 3 groups, to the TCM group, Chinese drug medication according to patients' SD (intravenons injection, decoction or Xiaoji Decoction) was given, to the WM group chemorherapy was given, and to the TCM-WM group, all the treatment used in both TCM and WM group were given. The long-term efficacy was analyzed by Kaplan-Meier method, the 24 prognostic factors that influencing survival rate were analyzed by COX regression model multiple factors analysis to screen the risk factor and protective factor.
Results: The median survival period in the TCM group was 285.00 +/- 17.92 days, in the WM group was 265.00 +/- 1.80 days, insignificant difference was found between them (P > 0.05), that in the TCM-WM group was 359.00 +/- 7.00 days, which was longer than that in the above two groups with significance (P < 0.05). The half-year and 1-year survival rates in the TCM group were 84.4% and 18.1%, in the WM group 82.5% and 20.6%, and in the TCM-WM group 92.5% and 42.7%. The 1-year survival rate in the TCM-WM group was higher than that in the TCM and WM group with significant difference (P < 0.05). Analysis on 24 prognostic factors indicated that there was significant difference (P < 0.05) in influence of such factors on survival rate as clinical stage, lymph node invasion, complications, TCM Syndrome typing, lactate dehydrogenase, carcinoembryonic antigen (CEA), CA199, Karnofsky scoring before treatment, therapeutic method, total scores of quality of life, stability of treatment, CD3+, etc. The former seven were the risk factors for prognosis of midlate NSCLC patients, and the latter 5 the protective factors.
Conclusion: TCM-WM treatment could prolong patients' survival period, elevate the long-term survival rate, it could be taken as one of the best comprehensive therapies for mid-late NSCLC patients who have missed the opportunity of surgical resection.
