Capecitabine Plus Radiotherapy for Local Relapse Breast Cancer With Negative Her2 Tumours
- Registration Number
- NCT00434941
- Lead Sponsor
- Spanish Breast Cancer Research Group
- Brief Summary
This is a prospective, open-label, multicenter phase IV.II study. Patients with local relapse breast cancer will receive radiotherapy concomitant to the administration of capecitabine.
- Detailed Description
Total dose of radiotherapy will be 50 Gy administered in daily session of 200 centigray (cGy). Radiotherapy treatment will not be longer than 6 weeks.
All patients will receive 1650 mg/m2 by mouth, per day (825 mg/m2 twice a day (p.o. bid) for 35 days.
Tissue samples must be analysed to determinate the human epidermal growth factor receptor-2 (HER2) by fluorescent in situ hybridization (FISH) technical.

Group Intervention Description Radiotherapy + Capecitabine Capecitabine Radiotherapy (for 25 days; Dose: 50 Gy) + Capecitabine (for 35 days; Dose: 825 mg/m2 twice per day p.o.) Experimental treatment consists of administration of 825 mg/m2 x 2 daily p.o., for 7 days simultaneously with daily radiotherapy treatment.Capecitabine will be administered for 35 days as maximum. Radiotherapy + Capecitabine Radiotherapy Radiotherapy (for 25 days; Dose: 50 Gy) + Capecitabine (for 35 days; Dose: 825 mg/m2 twice per day p.o.) Experimental treatment consists of administration of 825 mg/m2 x 2 daily p.o., for 7 days simultaneously with daily radiotherapy treatment.Capecitabine will be administered for 35 days as maximum.
- Primary Outcome Measures
Name Time Method Complete clinical response rate 28 days after the end of the radiotherapy The disease evaluation will be measured by RECIST criteria in the 28 days after the end of the radiotherapy by Magnetic resonance imaging (MRI).
- Secondary Outcome Measures
Name Time Method Evaluation of the concomitant administration of capecitabine and radiotherapy as the first treatment 28 days after the end of the radiotherapy Safety will be assessed by standard clinical and laboratory tests. Adverse events grade will be defined by the National Cancer Institute Common Terminology Criteria for Adverse (NCI-CTCAE).
