Resumen
Fecha de inicio: 1 de julio de 1996
Fecha en la que se inscribió al primer participante.OBJECTIVES: Compare the effect of irradiation of the homolateral internal mammary and medial supraclavicular lymph node chains vs no further therapy on survival, disease-free survival, metastasis-free survival, and cause of death in women with resected stage I/II/III breast cancer. OUTLINE: This is a randomized, multicenter study. Patients are stratified by participating institution, tumor location, type of prior breast surgery, pathologic T and N stage, menopausal status, and time sequence of radiotherapy and adjuvant chemotherapy. Patients are randomized to 1 of 2 arms. Arm I: Patients receive no nodal irradiation. Arm II: Patients receive irradiation of the internal mammary and medial supraclavicular lymph node chains delivered at 1 fraction per day, 5 sessions per week, for a total of 25 fractions over 5 weeks. Radiotherapy must begin no later than 8 weeks after surgery. If adjuvant chemotherapy is given, radiotherapy begins within 6 weeks after the last course of chemotherapy and within 8 months after surgery. Patients are followed at least yearly after randomization for up to 20 years. PROJECTED ACCRUAL: A total of 4,000 patients will be accrued for this study within 4 years.
