Effectiveness and Tolerability of Nab-paclitaxel in Younger versus Elderly Patients With Metastatic HR-positive/HER2-negative Breast Cancer: Results From the Noninterventional, Prospective Study NABUCCO.

Treatment with nab-paclitaxel in first- or further-line of metastatic HR-positive/HER2-negative breast cancer resulted in similar effectiveness and safety, irrespective of age. Therefore, nab-paclitaxel is a valid treatment option for elderly and partially heavily pretreated patients. However, incidence of TIPN is high, influencing the patients' quality of life. A close monitoring and awareness for early TIPN symptoms is warranted.
