Brief summary
Chemotherapy is an important means to prolong the survival time of advanced breast cancer. As a new type of microtubule inhibitor, eribulin has a unique mechanism of action. Compared with single drug chemotherapy, it can improve the overall survival time of 2.5 months, increase the clinical benefit rate by 5 times, and the tolerance of eribulin is good. Therefore, the guidelines at home and abroad recommend eribulin for the rescue of advanced breast cancer. However, up to now, there is no large sample data on the efficacy of eribulin combined with anti HER2 targeted therapy in HER2 + metastatic breast cancer, and the efficacy of combined immunotherapy in triple negative metastatic breast cancer. Moreover, as a newly marketed chemotherapy drug in China, the efficacy and safety data of eribulin in Chinese population are relatively lacking. Therefore, we plan to include different types and line numbers of advanced breast cancer patients based on the Chinese population through real-world research, and receive the treatment regimen containing eribulin respectively. In HR + / her2-mbc, we use eribulin monotherapy; in HER2 + MBC, we use eribulin + anti HER2 targeted therapy; in TNBC, we use eribulin + immunotherapy / chemotherapy, The efficacy and safety of eribulin were evaluated.

The starting time of eribulin treatment was between January 2021 and December 2021; 3. They received no more than 2-line chemotherapy in the past; 4. In HR + / her2-mbc, patients were treated with eribulin monotherapy; in HER2 + MBC, patients were treated with eribulin + anti HER2 targeted therapy; in TNBC, patients were treated with eribulin + immunotherapy / chemotherapy; in patients with HER2 + MBC, patients were treated with eribulin + immunotherapy /chemotherapy;
Exclusion criteria
1. Patients without pathological diagnosis; 2. Patients with central nervous system metastasis; 3. She has received more than two chemotherapy regimens for metastatic breast cancer; 4. Participating in any intervention drug clinical trials. 5. Those who have been known to have allergic history to the components of this regimen; 6. The patient, the patient, or the person with serious harm to the safety of the study. 7. Any other situation in which the researcher considers that the patient is not suitable for the study may interfere with the concomitant diseases or conditions involved in the study, or there are any serious medical barriers that may affect the safety of the subjects (e.g., uncontrollable heart disease, hypertension, active or uncontrollable infection, active hepatitis B virus infection)
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Progression Free Survival,PFS | up to 24 month | The time from the beginning of treatment to the progression or death of the patient |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| overall survival,OS | up to 36 month | The time from the beginning of treatment to the death of the patient |
| Quality of life scale score,QoL | up to 24 month | The quality of life score of patients during treatment was analyzed(FACT-B). Performance Status Rating (PSR) was demonstrated for the FACT-B total score, which is the result of the following subscale scores: SWB (the Social / family Well-Being subscale) , EWB (the Emotional Well-Being subscale), AC (Additional Concerns subscale), PWB (the Physical Well-Being subscale), FWB (the Functional Well-Being subscale) Performance Status Rating (PSR) was demonstrated for the FACT-B total score, which is the result of the following subscale scores: SWB (the Social / family Well-Being subscale) , EWB (the Emotional Well-Being subscale), AC (Additional Concerns subscale), PWB (the Physical Well-Being subscale), FWB (the Functional Well-Being subscale) |
| Complete remission, CR | up to 12 month | all target lesions disappeared, no new lesions appeared, and tumor markers were normal, which lasted for at least 4 weeks |
Other
| Measure | Time frame | Description |
|---|---|---|
| Clinical benefit rate, CBR | up to 12 month | according to recist1.1 criteria, the proportion of patients with Cr or PR or SD ≥ 24 weeks in the total number of evaluable patients. |
| Partial remission, PR | up to 12 month | the diameter of target lesions diminished more than 30% and lasted for 4 weeks |
| the rate of adverse events | up to 24 month | The probability and severity of adverse reactions were analyzed up to 2 year after enrollment |
| Exploration of biomarkers | the first week after the enrollment | Objective to explore the correlation between biomarkers and the ORR. The biomarkers will be test by nest-generation sequence, which include 520 genes and tumor mutation burden, like ERBB2/TP53/PIK3CA/ERBB4/CCND1 and so on. |
| Disease stable, SD | up to 12 month | the sum of the maximum diameter of the target lesion is smaller than PR, or the increase is not up to PD |
| Disease progression, PD | up to 12 month | he sum of the maximum diameter of the target lesion increased by at least 20%, and its absolute value increased by at least 5 mm, New lesions are also considered as PD |
| Objective response rate , ORR | up to 12 month | according to recist1.1 criteria, the proportion of patients whose best remission is CR or PR in the total number of evaluable patients. |
