Effect of Acupoint Application on Cardiotoxicity Induced by Doxorubicin Chemotherapy for Breast Cancer

Objective To observe the effect of acupoint application on cardiotoxicity induced by Doxorubicin chemotherapy for breast cancer.Method Sixty-four patients in early-stage invasive breast cancer who were going to receive 4 cycles of Doxorubicin-assisted chemotherapy were divided into an acupoint application group and a control group by the random number table,with 32 cases in each group.The acupoint application group received Chinese medicinal acupoint application 30 min before each chemotherapy cycle started,and the rest treatments were same as in the control group.The Karnofsky Performance Status(KPS)score,symptom and sign score,cardiotoxicity intensity,myocardial enzyme levelsCardiac troponinⅠ(cTnⅠ)and creatine kinase isoenzyme MB(CK-MB)],electrocardiogram(ECG)and left ventricular ejection fraction(LVEF)were observed before and after chemotherapy in each group.Result There were no significant differences in the KPS and symptom and sign scores before chemotherapy between the two groups(P>0.05);the symptom and sign score increased after chemotherapy in both groups(P<0.05),but was significantly lower in the acupoint application group than in the control group(P<0.05);the KPS score decreased remarkably in the control group after chemotherapy(P<0.05),and was significantly lower than that in the acupoint application group(P<0.05).The acupoint application group showed milder cardiotoxic reactions compared with the control group,with statistical significance(P<0.05).There were no significant between-group differences in the levels of cTnⅠ,CK-MB and LVEF before chemotherapy(P>0.05);the levels of cTnⅠand CK-MB increased(P<0.05)and the LVEF decreased(P<0.05)after chemotherapy in both groups;after chemotherapy,the level of cTnⅠwas lower in the acupoint application group than in the control group(P<0.05),and the LVEF was higher(P<0.05).The ECG variation rate was lower in the acupoint application group than in the control group after chemotherapy,and the difference was statistically significant(P<0.05).Conclusion Acupoint application can reduce the cardiotoxicity caused by Doxorubicin chemotherapy for breast cancer and can improve cardiac function.
