Risk-Stratified Hypofractionated Radiotherapy After Breast-Conserving Surgery for Early Breast Cancer
A Prospective Study of Risk-Stratified Hypofractionated Radiotherapy After Breast-Conserving Surgery for Early Breast Cancer
연구 개요
상태
상세 설명
Eligible patients with early breast cancer who have undergone breast-conserving surgery will be stratified into a high-risk group or a low-risk group according to the presence or absence of predefined high-risk factors.
Patients in the high-risk group will receive whole-breast irradiation with a simultaneous integrated boost to the tumor bed. The prescribed dose will be 36 Gy in 15 fractions over 3 weeks to the whole breast and 48 Gy in 15 fractions over 3 weeks to the tumor bed.
Patients in the low-risk group will receive partial-breast irradiation. Two hypofractionated schedules may be used: 40.05 Gy in 15 fractions over 3 weeks or 26 Gy in 5 fractions over 1 week.
Patients will be followed during and after radiotherapy to evaluate treatment efficacy, recurrence rates, and acute and late radiation-related toxicities.

활성 비교기: Arm 1: High-risk group
Patients who undergo upfront breast-conserving surgery will be assigned to the high-risk group if any of the following high-risk factors are present:
Patients who receive neoadjuvant chemotherapy followed by breast-conserving surgery will be assigned to the high-risk group if any of the following high-risk factors are present:
|
Whole-breast irradiation: 36 Gy in 15 fractions; Tumor bed boost: 48 Gy in 15 fractions
|
|
활성 비교기: Arm 2: Low-risk group
Patients who undergo upfront breast-conserving surgery will be assigned to the low-risk group if they meet either of the following criteria: ① Ductal carcinoma in situ (DCIS): age 40 years or older, unifocal disease on breast MRI, tumor size 3 cm or smaller, estrogen receptor-positive disease, and low-, intermediate-, or high-grade disease. ② Invasive carcinoma, including invasive ductal carcinoma, mucinous carcinoma, papillary carcinoma, or tubular carcinoma: age 40 years or older, unifocal disease on breast MRI, tumor size 3 cm or smaller, grade 1 to 3 disease, no lymphovascular invasion, and estrogen receptor-positive disease. Patients who receive neoadjuvant chemotherapy followed by breast-conserving surgery will be assigned to the low-risk group if all of the following criteria are met: Age 40 years or older, unifocal disease on pretreatment breast MRI, pretreatment core needle biopsy showing invasive ductal carcinoma, and pathologic stage ypT0/isN0. |
Partial-breast irradiation: 40.05 Gy in 15 fractions or 26 Gy in 5 fractions
