EBCTCG meta-analysis revealed a significant reduction in mortality in patients receiving chemotherapy irrespective of nodal status and ER status. Compared with CMF, 5-year RFS and OS favored the anthracycline-containing regimens, 57% vs 54% (p = 0.006) and 72% vs 69% (p = 0.02), respectively. No survival benefit was obtained for CMF durations greater than 6 months. Delaying radiation therapy for several months after breast-conserving surgery until the completion of adjuvant chemotherapy appears safe and may be preferable for patients at high risk of distant metastasis. No difference in disease-free survival for the 3 dose levels of doxorubicin (60, 75, and 90 mg/m2) was found. Higher doses (100 mg/m2) of epirubicin led to a high survival rate in women with poor-prognosis disease. Dose-dense therapy seems promising but still needs further investigation. Incorporation of taxanes into adjuvant chemotherapy for early breast cancer is also controversial.
