Nab-paclitaxel in Treatment of Metastatic Breast Cancer

Abstract

Despite the development of new systems for the treatment of metastatic breast cancer (mBC), chemotherapy remains an integral and significant stage of treatment for any molecular tumor subtype. In accordance with modern concepts, the optimal strategy of therapy in the vast majority of cases of mBC is the sequential administration of cytostatics in mono modes. This approach allows long-term control of tumor growth, translating pathology into a chronic discharge and maintaining a high quality of life. The emergence of new drugs or innovative dosage forms of existing cytostatics expands the possibilities of treatment of this chronic disease and allows long-term control over the disease. One of such new options was nab-paclitaxel, nano-dispersed paclitaxel stabilized with albumin. This dosage form provides active transport of the drug through the vascular endothelium with the creation of its high concentration in the tumor tissue. Clinical studies comparing nab-paclitaxel with traditional taxanes (paclitaxel and docetaxel) demonstrated high efficacy and safety of the drug both in a wide population of patients and in individual subgroups, including patients previously treated with anthracycline taxane, cases with aggressive disease, lesions of visceral organs, elderly patients and others. In addition, due to its unique formula, the drug does not cause hypersensitivity reactions, differing from traditional These taxanes are easy to use and safe. The lack of need for premedication with dexamethasone allows it to be prescribed for such comorbidities as severe hypertension, diabetes mellitus, stomach ulcer and duodenal ulcer, etc., and also successfully combine it with inhibitors of control points of the immune response, which confidently removes the drug on arena of immuno-oncology.
