Choice of adjuvant therapy for HER2-positive breast cancer in real clinical practice: analysis of physician preferences in the Russian Federation
Adjuvant therapy with trastuzumab made a significant contribution to improving disease-free and overall survival rates in patients with HER2-positive breast cancer. However, in a number of clinical situations the risk of disease recurrence remains increased. Carrying out neoadjuvant treatment followed by post-neoadjuvant therapy, depending on the degree of pathomorphological response, is the modern standard, allowing to cure a significantly larger number of patients. This became possible thanks to the expansion of the arsenal of terget anti-Her drugs and the introduction into real clinical practice of double anti-HER2 blockade (trastuzumab + pertuzumab) and an antibody conjugate with a cytostatic drug – trastuzumab emtansine. To assess actual clinical practice in the Russian Federation, a survey study “Therapy of HER2-positive breast cancer” was conducted. The survey involved 50 specialists from different regions of the country who are directly involved in developing a treatment plan for patients, which allows them to reflect the preferences of leading chemotherapists regarding tactics for HER2-positive breast cancer. This publication reflects the results of part of the survey, devoted to the choice of adjuvant and post-neoadjuvant therapy for HER2-positive breast cancer. Identified a clear positive trend in favor of neoadjuvant treatment followed by post-neoadjuvant therapy using modern targeted drugs such as pertuzumab and trastuzumab emtansine. The survey results show that 68% of patients with RCB-II–III residual tumor receive post-neoadjuvant trastuzumab emtanzine, in 2021 this figure was only 24%. The absolute majority of patients who have not received neoadjuvant therapy, but have N2–3 stage, receive double anti-HER2 therapy with trastuzumab + pertuzumab in the adjuvant setting.
