About this trial
This study investigates the safety and efficacy of hypofractionated radiotherapy (HFRT) versus conventional fractionated radiotherapy (CFRT) in breast cancer patients undergoing total mastectomy with prosthetic reconstruction.
Study Design Population: Patients with high-risk breast cancer after mastectomy and immediate implant reconstruction.
Intervention:
HFRT Arm: 43.5 Gy in 15 fractions (2.9 Gy/fraction, 3 weeks). Control Arm: CFRT (50 Gy in 25 fractions, 2 Gy/fraction, 5 weeks). Endpoints Primary: Reconstruction failure rate (e.g., implant removal, capsular contracture)
