Intervention / TreatmentIntervention / Treatment |
|---|---|
|
Active Comparator: Study Arm
Investigational treatment: Arimidex commenced before and continued during radiotherapy. Interventions: Drug: Pre-radiotherapy commencement of Arimidex Radiation: Radiotherapy |
Arimidex:1mg P.O.
daily will be prescribed for 8 weeks in post-mastectomy patients and 9 weeks in BCT patients within the study period.
Arimidex starts 3 weeks before adjuvant radiotherapy and throughout the course of radiotherapy.Total duration of adjuvant hormonotherapy is prescribed by the investigators at the completion of study, 5 years in principle.
Other Names:
Radiotherapy is delivered to the whole breast/chest wall +/- regional lymph nodes to a total dose of 50Gy/25 fractions/5weeks, an additional tumor bed boost of 10Gy/5 fractions/1week is delivered to patients with breast conservative surgery
Other Names:
|
|
Active Comparator: Control Arm
Standard Treatment: Arimidex delayed until 2 weeks after radiotherapy Interventions: Radiation: Radiotherapy Drug: Post radiotherapy commencement of Arimidex |
Radiotherapy is delivered to the whole breast/chest wall +/- regional lymph nodes to a total dose of 50Gy/25 fractions/5weeks, an additional tumor bed boost of 10Gy/5 fractions/1week is delivered to patients with breast conservative surgery
Other Names:
Arimidex:1mg P.O.
daily will be prescribed at 2 weeks after the end of radiotherapy.Total duration of adjuvant hormonotherapy is prescribed by the investigators at the completion of study, 5 years in principle.
