Recruiting now · Not applicable
Conditions studied: Breast Cancer
In brief
The study was designed to investigate whether hypofractionated radiotherapy(HF-RT) is noninferior to conventionally fractionated radiotherapy (CF-RT) in terms of tumor loco-regional control for patients after breast conserving surgery

Who can join
Age: 18 and older, up to 70. Sex: female. Healthy volunteers: not accepted.
You may qualify if…
- Female
- Age18-70 years
- Imaging examination confirmed single lesion. if the tumor is multiple, it needs to be removed by single quadrantectomy
- Receive breast conserving surgery with negative margins
- Axillary lymph nodes treatment: Sentinel lymph node biopsy or level I/II axillary lymph node dissection. If the sentinel lymph node is negative, the axillary lymph node dissection can be omitted. If it is positive, level I/II axillary lymph node dissection with or more than 10 lymph nodes is needed.
- The tumor bed is labeled with clips and it can be drawn on the treatment planning system.
- Pathologically confirmed invasive breast cancer
- Pathologically stage is T1-3N0-3M0
- Immunohistochemical examination is conducted to determine the status of ER, PR, HER2, Ki67 after surgery
- No distant metastases
- No supraclavicular or internal mammary nodes metastases
- No neoadjuvant chemotherapy
- Fit for postoperative radiotherapy. No contraindications to radiotherapy
- KPS≥80
- Signed informed consent
You may not qualify if…
- T4 or M1 breast cancer
- Supraclavicular or internal mammary nodes metastases
- Pathologically confirmed DCIS only without an invasive component
- Bilateral breast cancer or historically confirmed contralateral invasive breast cancer
- Treated with neoadjuvant chemotherapy or neoadjuvant endocrine therapy
- Multiple lesions can not be removed by single quadrantectomy
- Suspicious unresected and microcalcification, densities, or palpable abnormalities (in the ipsilateral or contralateral breast)
- KPS ≤ 70
- Patients with severe non-malignant comorbidity in cardiovascular or respiration system
- Concurrent or previous malignancy excluding basal or squamous cell carcinoma of the skin
