| Popis: | The purpose of this study was to determine the importance of the dose of adjuvant chemotherapy in patients with breast cancer, and to determine which variables had influence on the dose of chemotherapy received. We reviewed the records of 196 patients with node-positive breast carcinoma that were treated with anthracycline-based adjuvant chemotherapy. We analyzed the influence on treatment efficacy of the dose of anthracyclines (total dose and dose intensity), and a multivariate analysis was performed to identify independent prognostic factors of chemotherapy total dose. There were no differences in disease-free survival or overall survival between patients who received doses below or above the median total dose and median dose intensity of anthracyclines. A positive correlation was observed between the total dose of anthracycline received and the number of axillary lymph nodes. The clinical outcome of patients with node-positive breast cancer receiving adjuvant anthracycline-based chemotherapy is not affected by the amount of chemotherapy delivered. There exists a clinical practice of administering more chemotherapy in patients with poorer prognosis, which does not result in better therapeutic outcomes. |
