Abstract:
Objective:To investigate the current trend of breast cancer neoadjuvant therapy and provide reference for the improvement of breast cancer clinical guideline in the future.Methods:Questionnaires of cross-sectional survey were sent to 110 hospitals (breast cancer surgery quantity surpassing 200) between July 2018 and September 2018. The stages and subtypes, therapeutic regimen, treatment assession, operation choice and preforming of patients underwent neoadjuvant therapy were recorded.Results:Neoadjuvant treatment has been performed in all of the 110 hospitals. The total number of breast patients underwent neoadjuvant therapy was about 14 550 (17.0% in surgical patients) in 2017. For all of the neoadjuvant patients, the proportion of stageⅡ patients was less than 30% in 81 hospitals, and the proportion of stage Ⅲ was more than 50% in 84 hospitals. The numbers of estrogen receptor (ER) (+ )/human epidermal growth factor receptor-2 (HER-2) (-), ER (-)/HER-2 (+ ) and triple negative subtype breast cancer patients were 3 550 (24.4%), 6 024 (41.4%) and 4 991 (34.3%), respectively. Patient′s scruples of relatively delayed operation and weak will of breast conservation after neoadjuvant therapy were the majority reasons for neoadjuvant therapy restriction. Anthracycline followed by taxane was the most usual neoadjuvant therapeutic regimens in 53.6% hospitals, and anthracycline plus taxane was the first choice in 42.7% hospitals. Chemotherapy with targeting therapy was recommended to HER-2 positive neoadjuvant patients in 80.9% hospitals. To assess treatment outcome of neoadjuvant treatment, 42.7% hospitals used MRI in more than 50% patients while the usage rate of MRI was less than 20% in 37.3% hospitals. The proportions of hospital using repeat-marking, tattoo and metal clip as the first method to identify the primary tumor region and lymph nodes were 60.0%, 29.1% and 10.9%, respectively. Breast-conservation rate after neoadjuvant therapy was less than 20% in 87.3% hospitals.Conclusions:Neoadjuvant therapy for breast cancer is widely performed in most hospitals in China, while the proportion of neoadjuvant treatment in patients with operable breast cancer is still low. Meanwhile, the idea of achieving de-escalation operation through neoadjuvant treatment is not promoted and the therapeutic evaluation method of neoadjuvant treatment needs further studies to improve.
