[Abstract]
Objective To investigate the preventive and therapeutic effect of Yiqi Fumai Lyophilized Injection (YQFM) on myocardial injury after targeted therapy (trastuzumab for injection + lapatinib toluenesulfonate tablets) for breast cancer surgery. Methods A total of 100 patients with HER-2 positive breast cancer admitted to the Affiliated Hospital of Guizhou Medical University from 2021 March to 2024 March were randomly divided into an observation group and a control group with 50 patients in each group. The control group was treated with injection of trastuzumab and lapatinib tosylate tablets for 21 d per cycle. The observation group received targeted therapy similar to the control group. Three days before each targeted therapy cycle, YQFM was used, with eight bottles (5.2 g) intravenously administered once a day for 14 consecutive days. The traditional Chinese medicine symptoms of the two groups of patients were scored before targeted therapy and after two and four cycles of treatment. The left ventricular ejection fraction (LVEF) was examined by ultrasound, serum creatine kinase (CK), creatine kinase isoenzyme (CK-MB), lactate dehydrogenase (LDH) levels were detected, myocardial injury markers [cardiac troponin I), brain natriuretic peptide (BNP)] and electrocardiogram changes were detected, and the quality of life was evaluated. Results Before targeted therapy, there was no statistically significant difference in various indicators such as traditional Chinese medicine symptom scores, heart function, myocardial enzymes, and myocardial injury markers between the two groups (P > 0.05). After four cycles of treatment, the total effective rates of the observation group and the control group were 92% and 72%, respectively, and the difference between the groups was statistically significant (P < 0.05). There was no statistically significant difference (P > 0.05) in the TCM symptom scores of myocardial injury symptoms (chest tightness, chest pain, palpitations, chills, and lower limb edema) between the two groups of patients before targeted therapy. After two and four cycles of treatment, LVEF in both groups was significantly lower than before targeted therapy in the same group (P < 0.05), and after four cycles of treatment, LVEF was significantly lower than after two cycles of treatment (P < 0.05); However, the LVEF of the observation group was significantly higher than that of the control group after two and four cycles of treatment (P < 0.05). The levels of serum CK, CK-MB, and LDH in the control group were higher than before targeted therapy after two and four cycles of treatment (P < 0.05), and were significantly higher after four cycles of treatment than after two cycles of treatment (P < 0.05). The serum CK-MB and LDH levels in the observation group were significantly higher than before targeted therapy after two and four cycles of treatment (P < 0.05), but the serum CK-MB and LDH levels were lower than those after two cycles of treatment and significantly lower than those in the control group at the same time (P < 0.05). The serum levels of cTnI and BNP in the control group were higher than before targeted therapy after two and four cycles of treatment (P < 0.05), and were significantly higher after four cycles of treatment than after two cycles of treatment (P < 0.05). After two and four cycles of treatment, the serum levels of cTnI and BNP in the observation group were higher than before targeted therapy (P < 0.05), but after four cycles of treatment, the serum levels of cTnI and BNP were lower than after two cycles of treatment and significantly lower than those in the control group at the same time (P < 0.05). After two and four cycles of treatment, the scores of various indicators of quality of life in both groups were higher than before targeted treatment in this group (P < 0.05), and the observation group was significantly higher than the control group (P < 0.05). After two and four cycles of treatment, the number of abnormal electrocardiograms in both groups increased significantly compared to before treatment (P < 0.05), but the increase in the observation group was less than that in the control group (P < 0.05). Conclusion YQFM can improve the clinical symptoms of HER-2 positive breast cancer patients after targeted therapy, inhibit the decline of LVEF, protect myocardium, improve patients' tolerance to myocardial injury caused by targeted therapy, and prevent myocardial injury events.
