Official title
A Prospective Phase II Study of Radiation Therapy to Treat Refractory Breast Cancer
Overview
For locally advanced or recurrent metastatic breast cancer that is resistant to systemic therapy, radiotherapy (RT) may be considered as the preferred treatment option when the lesion is unresectable, or the patient is not suitable for surgery. This study aim to evelatuate the local control of radical dose RT or new RT technique (such as patially fractionated radiation therapy, SFRT) for the locally advanced or recurrent metastatic breast cancer.
Interventions
- Radiation Radical dose radiotherapy
Radical dose is delivered for the patients. SFRT is recommended for the patients with bulky tumor (such as ≥ 5cm). SFRT is delivered with 12-20Gy (1 fraction) followed by external beam radiation therapy (EBRT) with EQD2≥60Gy.
Primary outcome measures
- Overall Response Rate (ORR) [Time frame: 3 months]
Secondary outcome measures (5)
- Overall Response Rate (ORR) [Time frame: 1 month]
- Local control [Time frame: 1 year]
- Progression-Free Survival (PFS) [Time frame: 1 year]
- Overall Survival (OS) [Time frame: 1 year]
- Number of participants with treatment-related acute and late adverse events as assessed by CTCAE v5.0 [Time frame: 1 year]
Eligibility criteria
Inclusion criteria

- Signature of informed consent form.
Exclusion criteria
- Pregnant or lactation women;
