Abstract
Objective To analyze the effect of epirubicin-based chemotherapy on cardiotoxicity of breast cancer female patients combined with diabetes.Methods A total of 108 female patients underwent radical resection of the tumor in the breast center of Fourth Hospital of Hebei Medical University from October 2013 to October 2015 were selected and were clearly diagnosed with breast cancer after the pathological examination.The epirubicin-based chemotherapy(epirubicin+cyclophosphamide) was conducted firstly,3 weeks a course and totally 6 courses.Among the subjects,55 patients combined with type 2 diabetes were assigned into diabetic chemotherapy group and 53 patients not combined with diabetes were assigned into non-diabetic chemotherapy group.At the same time,50 age-matched female diabetic patients without breast cancer in the outpatient of endocrinology department were selected as the diabetic control group.Measurement of routine indicators,Doppler ultrasound inditators,and oxidative stress indicators were conducted to patients with breast cancer before the application of chemotherapy regimens(baseline) and after chemotherapy,and to patients in diabetic control group at the time of enrollment and after 4.5 months.Results Fifty patients were selected from diabetic chemotherapy group and non-diabetic chemotherapy group respectively.At baseline,total cholesterol,triglyceride and glycosylated hemoglobin in diabetic chemotherapy group and diabetic control group were higher than those in non-diabetic chemotherapy group(P<0.05).There were no significant differences in Δbody mass index,Δblood pressure,Δhemoglobin,Δtotal cholesterol,Δtriglyceride and Δglycosylated hemoglobin among patients in the three groups after chemotherapy(P>0.05).At baseline,E/Ea in diabetic chemotherapy group and diabetic control group was higher than that in non-diabetic chemotherapy group(P<0.05).At the end of chemotherapy,ΔEa in diabetic chemotherapy group was significantly lower than that in diabetic control group and non-diabetic chemotherapy group,and its ΔE/Ea was significantly higher than that in diabetic control group and non-diabetic chemotherapy group(P<0.05).At baseline,SOD in diabetic chemotherapy group and diabetic control group was lower than that in non-diabetic chemotherapy group,MDA was higher than that in non-diabetic chemotherapy group(P<0.05).After chemotherapy,there were significant differences in ΔSOD and ΔMDA in pairwise comparison between groups(P<0.05).Conclusion The epirubicin-based chemotherapy leads to a significant aggravation in diastolic dysfunction among female breast cancer patients combined with diabetes,and indicates that combination of diabetes aggravates themyocardial damage of the epirubicin-based chemotherapy.关键词
