Abstract
OBJECTIVE: This study used a prospective cohort study to observe the effect of triple-negative breast cancer on the 2-year disease-free survival rate with or without "TCM formula". METHODS: From November 1 st, 2016, the first patient was enrolled in the cohort study. A total of 356 patients were enrolled on January 30, 2019. Among them, 154 cases were followed up for 2 years. During the follow-up, there were 6 cases of shedding, so 6 cases were affected. A total of 148 cases were included in the analysis, including 73 in the exposed group and 75 in the non-exposed group. The exposed group was given "TCM formula" on the basis of standardized treatment, and the non-exposed group was treated with simple triple-negative breast cancer. The two groups visited each of the three months. The interview included safety examination (hematology and imaging). The endpoint was the difference in 2-year invasive disease-free survival between the exposed and non-exposed groups and the safety of the "TCM formula". RESULTS: There were 6 cases of shedding during the experiment and the shedding rate was 3.9 %. The 2-year rate of invasive disease-free survival in the exposed team was 88.7 % and the non-exposed group was 82.5 %. Logistic multivariate regression analysis predicted that "TCM formula" could reduce the disease-related recurrence and metastasis rate by 11 % (OR = 0.89, 95 % CI 0.37-0.956, P＜0.05). Through K-M survival analysis, TNBC patients with age ≤35 years and regional lymph node stage N1 may be the benefit group of "TCM formula"(P＜0.05). During the study, the incidence of total adverse events was 8.2 % in the exposed group, mainly manifested as stomach discomfort, diarrhea, and hepatocyte damage. CONCLUSION: 1. In the exposed group, the two-year rate of invasive disease-free survival increased by 6.2 % compared with the non-exposed group(P＞0.05). 2. According to K-M survival analysis, TNBC patients with age ≤35 years and regional lymph node metastasis to N1 may be potential beneficiaries of "TCM formula". 3. "TCM Formula" is safe and tolerable to most patients.
