简要总结
PURPOSE: This phase II trial studied how well radiation therapy works after surgery in treating women with phyllodes tumor of the breast.
RATIONALE: Radiation therapy uses high-energy x-rays to damage tumor cells. Radiation therapy following surgery may be effective in treating patients with phyllodes tumor of the breast.
详细描述
OBJECTIVES:
- Determine the local recurrence rate in women with phyllodes tumors of the breast previously treated with local excision with negative margins and are now treated with adjuvant radiotherapy.
- Determine the survival rate in patients treated with this regimen.
METHODS: Within 12 weeks after prior local excision or breast reexcision, patients underwent adjuvant radiotherapy 5 days a week for a total of 28 treatments. Patients were then followed every 6 months for 10 years.
