A Study for the Neoadjuvant Treatment of Breast Cancer
Trial Parameters
Brief Summary
Due to the unique advantages of albumin-bound paclitaxel, several studies in China and abroad have tried to use albumin-bound paclitaxel for neoadjuvant treatment of breast cancer up to now. However, comparative studies between paclitaxel and docetaxel are still rare, In this study, a prospective, randomized, open-label, multi-center clinical study was conducted to analyse the efficacy and safety of albumin-bound paclitaxel and docetaxel in the neoadjuvant treatment of breast cancer, 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.
