Effect analysis of prophylactic anticoagulation in the patients with non-small cell lung cancer / 国际肿瘤学杂志

ABSTRACT

Objective To evaluate the effect of anticoagulant therapy in the patients with non-small cell lung cancer (NSCLC).Methods One hundred and fifty-nine patients with NSCLC without venous throm-boembolism (VTE)were divided into anticoagulant therapy group (81 cases)and control group (78 cases)by random number table method.The 81 cases in anticoagulant therapy group were treated with anti-tumor therapy and anticoagulant therapy,using low molecular heparin calcium 5 000 U subcutaneous injected for 1 0-30 days, once every 1 2 hours.The 78 cases in control group were merely treated with anti-tumor therapy.Results After treated with anticoagulation therapy,patients in anticoagulant therapy group had prolonged prothrombin time [(1 3.56 ±4.30)s vs (1 5.1 6 ±2.1 2 )s;t =3.1 95,P =0.001 ],active partial thromboplastin time [(28.24 ±5.28)s vs (30.26 ±3.28)s;t =2.71 2,P =0.007)],and a lower FIB [(3.85 ±0.75)g/l vs (4.25 ±2.65)g/l;t =2.971 ,P =0.003]compared with the patients in control group.The incidence of thrombosis rates of the two groups were 2.47% and 1 6.67% respectively,with statistical significance (χ2 =9.901 ,P =0.002).Both the 1 ,2 years overall survival rates of patients in anticoagulant therapy group were longer than those in control group,with statistical significances (χ2 =5.496,P =0.026;χ2 =4.540,P =0.046),while the 1 ,2 years progression-free survival rates of patients in the two groups were no statistical sig-nificances (χ2 =2.034,P =0.1 82;χ2 =0.091 ,P =0.395 ).Adverse reactions such as hemorrhage (4.94% vs 6.41 %),thrombocytopenia (9.88% vs 8.98%),skin necrosis incidence (3.70% vs 1 .28%) in the anticoagulant therapy group and control group were no statistical significances (χ2 =0.51 6,P =0.685;χ2 =0.008,P =1 .000;χ2 =0.847,P =0.632).Conclusion For patients with NSCLC,prophylactic antico-agulant therapy can improve coagulation status,reduce the incidence of thrombosis,prolong OS,and no obvi-ous adverse reactions.
