At present, the treatment of early-stage breast cancer is mainly surgical, supplemented by chemotherapy, endocrine therapy, radiotherapy, targeted therapy and other comprehensive treatment methods, through the use of a variety of comprehensive and individualized treatment plans led to a significant improvement in the quality of life and survival of breast cancer patients. Systematic adjuvant therapy after surgery is also gaining increasing attention, with a large number of randomized clinical trials worldwide . The effectiveness of adjuvant therapy in reducing the recurrence of breast cancer and improving survival has been demonstrated in a number of randomized clinical trials worldwide. Adjuvant therapy after surgery is recommended in NCCN guidelines, ESMO, St. Gallen and other guidelines or expert consensus.~The use of albumin paclitaxel in the postoperative adjuvant treatment of breast cancer has been reported overseas, and a phase II clinical study published in 2017 investigated the tolerability and feasibility of dose dense doxorubicin combined with cyclophosphamide followed by nab-paclitaxel (AC-nP) chemotherapy in patients with high-risk early-stage breast cancer in adjuvant treatment. The results suggested that this regimen was well tolerated, with an incidence of granular deficiency with fever 5 of 2%, suggesting the safety of weekly treatment with nab-paclitaxel.~Another study evaluated the safety of dose-dense AC-nP regimens in women with high-risk breast cancer. Enrolled patients received 4 cycles of AC (every 2 weeks) followed by nab-P (every 2 weeks). The most common eventual adverse reaction was peripheral neuropathy, although approximately 80% of patients were grade 1-2, and the patient's neuropathy gradually improved after the end of treatment. This suggests that in early breast cancer, the use of dose-dense AC followed by nab-P is feasible with predictable AEs .~In summary, studies on postoperative adjuvant albumin paclitaxel in domestic breast cancer patients are less reported, especially in large samples, and more studies focus more on the safety and tolerability of albumin paclitaxel use. Head-to-head studies of white violet and docetaxel are not supported by data at this time, but some studies have shown that docetaxel-induced long-term Other adverse effects such as myelosuppression, hepatotoxicity and hypersensitivity reactions can have a serious impact on quality of life. Therefore, this study aim to conduct a prospective, randomized, open-label, multi-center clinical study to analyse the efficacy and safety of albumin paclitaxel and docetaxel in the adjuvant treatment of breast cancer in a large randomized controlled trial, and to further analyse the efficacy and safety of albumin paclitaxel in combination with chemotherapy for postoperative breast cancer in different subtypes of breast cancer patients, in order to obtain more realistic data and provide new treatment options for breast cancer patients.
