The study was designed to investigate whether hypofractionated adjuvant radiotherapy is noninferior to conventionally fractionated adjuvant radiotherapy in terms of efficacy and toxicities for high risk breast cancer patients treated with mastectomy
The randomization is between 50 Gy / 25 fractions and 42.5 Gy/16 fractions, 5 fractions weekly.
Eligible breast cancer patients with mastectomy and axillary dissection will be randomized 1:1 into two groups: conventional fractionated (CF) radiotherapy of 50 Gy / 25 fractions and hypofractionated (HF) radiotherapy of 42.5 Gy/16 fractions, 5 fractions weekly.
The primary endpoint is loco-regional recurrence. Other cancer related events and acute/late radiation morbidities will also be evaluated. The patients will be followed for 10 years.
It is hypothesized that for women operated for high risk breast cancer with indication of postmastectomy adjuvant radiotherapy, hypofractionated radiotherapy is noninferior to conventional fractionated radiotherapy in terms of the efficacy and toxicities.

| Loco-regional recurrence (LRR) | Defined as any clinical and biopsy-proven tumor recurrence involving the ipsilateral chest wall and/or regional nodes (including axillary, supraclavicular, infraclavicular, or internal mammary nodes). Time to loco-regional recurrence is defined as the interval starting from the date of randomization until the event. LRR will be assessed every 3 months during the first 2 years after the last fraction received, every 6 months during the following 3-5 years and every year thereafter through 10 years | every 3 months during the first 2 years after the last fraction received, every 6 months during 3-5 years, every year during 6-10 years |
| Measure | Description | Time Frame |
|---|---|---|
| Distant metastasis free survival (DMFS) | Distant metastasis is defined as clinical detection of metastatic disease beyond the chest wall and/or regional lymph nodes or death or last visit. Distant metastasis free survival (DMFS) is defined as the interval starting from the date of randomization until to the event. Distant metastasis will be assessed every 3 months during the first 2 years after the last fraction received, every 6 months during the following 3-5 years and every year thereafter through 10 years. |

| every 3 months during the first 2 years after the last fraction received, every 6 months during 3-5 years, every year during 6-10 years |
| Disease free survival (DFS) | Defined as the interval from the date of randomization to any disease recurrence or death or last visit. It will be assessed every 3 months during the first 2 years after the last fraction received, every 6 months during the following 3-5 years and every year thereafter through 10 years | every 3 months during the first 2 years after the last fraction received, every 6 months during 3-5 years, every year during 6-10 years |
| Overall survival (OS) | Defined as the interval from the date of randomization to death or last visit. It will be assessed every 3 months during the first 2 years after the last fraction received, every 6 months during the following 3-5 years and every year thereafter through 10 years | every 3 months during the first 2 years after the last fraction received, every 6 months during 3-5 years, every year during 6-10 years |
| CTCAE Toxicity Assessment-Acute toxicity | Acute toxicity (development of radiation dermatitis, pruritus, pain, radiation esophagitis, and radiation pneumonitis) will be assessed according to toxicity criteria of CTCAE version 4.03 before treatment, every week of treatment, the end of treatment, 2 weeks, 3 months after the last fraction received and every year thereafter through 10 years | before treatment, every week of treatment, the end of treatment, 2 weeks, 3 months after the last fraction received, every year through 10 years |
