Breast cancer is the most frequent
cancer of women in developed countries. Systemic
adjuvant chemotherapy has dramatically improved the outcome of patients treated for early stage invasive
breast cancer. Among novel chemotherapeutic agents, the
taxanes have emerged as the most powerful compounds since anthracycline regimens. Two
taxanes are available (
paclitaxel and
docetaxel) and they share some characteristics, while having a number of significant differences, both in terms of preclinical and pharmacokinetic profiles and, most importantly, clinical consequences. In clinical practice, the
taxanes are now standard therapy in metastatic
breast cancer. Their role as monochemotherapy or in combination with
anthracyclines in advanced
breast cancer has suggested their potential therapeutic impact in the treatment of patients with early
breast cancer. Available results in the adjuvant and neoadjuvant setting demonstrate that
taxanes, used in combination with other chemotherapeutic agents or
trastuzumab, or in sequential therapy, possess the capability to induce significant improvements, in particular in terms of survival, confirming the positive impact of
taxanes on the natural history of
breast cancer.
