Treatment results and prognostic factors of early breast cancer treated with a breast conserving operation and radiotherapy.
The purpose of this study was to analyze the prognostic factors affecting local control and survival rates for patients with early breast cancer who received breast conserving treatment (BCT) and to find out the optimal treatment according to their risk factors. ⋯ The most important prognostic factor affecting local control, disease-free survival and overall survival was axillary lymph node metastasis. The nuclear grade influenced local control and disease relapse. Patients with multiple unfavorable risk factors such as positive axillary lymph nodes, high nuclear grade, young age and large tumor showed poorer local control and disease-free survival than patients without any risk factors, and so more aggressive treatment is required for these patients.
