To identify subgroup effects that might influence the survival results of postoperative radiotherapy. ⋯ The analyses found subgroup effects that should be taken into account to interpret treatment results in breast cancer.

More than 60% of patients with metastatic breast cancer receiving non-platinum-based chemotherapy experience anemia, which is associated with fatigue and impaired quality of life. Epoetin alfa treatment in patients with a variety of malignancies has been shown to decrease transfusion requirements and improve hemoglobin levels and quality-of-life efficacy parameters. ⋯ In the full study cohort and the breast cancer subpopulation, epoetin alfa effectively treated anemia (increased hemoglobin levels and decreased transfusion requirements) and improved or preserved quality of life. Results concerning potential survival benefits support further study of epoetin alfa in anemic cancer patients.

The aim of this study was to investigate the efficacy of postoperative locoregional radiotherapy in patients with T1-T2 breast cancer and four or more positive axillary lymph nodes submitted to mastectomy or breast-conserving surgery followed by standard-dose or high-dose adjuvant chemotherapy. The incidence of locoregional relapses and the survival correlated with the number of positive nodes were recorded for each treatment arm. ⋯ Breast cancer patients with four or more positive axillary lymph nodes are at high risk of developing locoregional and distant relapses. The results reported here demonstrate the efficacy of radiotherapy in the reduction of locoregional failure; no differences in survival and locoregional control in relation to treatment arm and number of positive nodes were found.
