One Week Adjuvant Radiotherapy for Breast Cancer
May 5, 2022 updated by: Nahla Mohamed Elmahdy, Sohag University
A Prospective Study of One Week Accelerated Hypo-fractionation Adjuvant Radiotherapy in High-risk Breast Cancer Patients
- Cancer is the second leading cause of death after cerebrovascular strokes and is a significant obstacle to each nation's future growth.
- Worldwide, Breast cancer is the most common cancer in women and the 5th leading cause of cancer related deaths that comes after lung cancer, colorectal cancer, liver cancer and gastric cancer.
- More than half of all breast cancer cases in the world occur in developing countries. Egypt has a high mortality rate from breast cancer, with a rate of 21.3 per 100,000 cases. Breast cancer is diagnosed at an advanced stage in 60 to 70% of cases in Egypt. The median age at diagnosis in Egypt is 48.5 years, which seems to be a decade younger than in Europe and North America.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Hypofractionation control arm
Patients who will receive 40 Gy in 15 fractions to the entire breast or chest wall over three weeks and have had breast conservation surgery (BCS) or oncoplastic breast surgery(OBS) will receive an additional boost to the tumour site if and will receive sequential dose 12GY\4 fractions or SIB 8GY 15 fractions.
The supraclavicular fossa will be treated in patients with node-positive disease or those who had received neoadjuvant chemotherapy .
The IMLN will be irradiated in N2and N3 at first presentation.
|
Patients will receive 40 Gy in 15 fractions to the entire breast and or chest wall over the course of 3 weeks.
Other Names:
|
Experimental: . Ultrahypofractionation experimental arm
Patients who will receive 26 Gy in 5 fractions to the entire breast and or chest wall for one week only.
The volume of this arm will be the same as the volume of the control arm as regard axillary nodes, supraclavicular and IMLN.
Patients who have had breast conservation or oncoplastic breast surgery(OBS) will be given a boost.
If a boost is given, SIB of 6 Gy in 5 fractions will be used (or a sequential boost of 12GY\4 fractions).
|
Patients will receive 26 Gy in 5 fractions to the entire breast and or chest wall over the course of one week.
