Outcomes of Intraoperative Radiotherapy for Early-Stage Breast Cancer: Experience from a Multidisciplinary Breast Oncology Program
ConclusionsIORT is a safe and effective alternative to whole breast radiotherapy, and serves as a suitable alternative to completion mastectomy in locally recurrent breast cancer.Summary for the table of contentsA multidisciplinary breast cancer center experience of intraoperative radiation therapy (IORT) in early stage breast cancer patients. Single high dose IORT was implemented in lieu of prolonged daily whole breast radiation as part of breast conserving therapy. IORT was found to be safe and effective alternative to WBRT in select early stage breast cancer patients.
ConclusionPRT/PCRT is associated with low grades of fibrosis and a good to excellent long-term cosmetic outcome.
This study evaluated the clinical significance of the lymph-node ratio (LNR) and its usefulness as an indicator of supraclavicular lymph-node radiation therapy (SCNRT) in pN1 breast cancer patients with disease-free survival (DFS) outcomes. We retrospectively analyzed the clinical data of patients with pN1 breast cancer who underwent partial mastectomy and taxane-based sequential adjuvant chemotherapy with postoperative radiation therapy in 12 hospitals (n = 1121). We compared their DFS according to LNR, with a cut-off value of 0.10. The median follow-up period was 66 months (range, 3–112). Treatment failed in 73...
This report details our experience using accelerated partial breast irradiation (APBI) as a component of salvage breast conserving treatment.
ConclusionPLM plays an important role in the evaluation of patients undergoing breast conservation for breast cancer presenting with microcalcifications. Residual malignancy was detected on positive PLM in 6% of patients with negative margins.
ConclusionLRR in this select group of early-stage patients with HER2-positive disease receiving effective anti-HER2 therapy is extremely low. If confirmed in additional studies, future investigational efforts should focus on de-escalating local therapy.
Conclusions: This study is the first to demonstrate a dose-response relationship between risk of complications and near Dmax, where hypofractionated regimen or boost RT can play an important role. Rigorous RT-quality assurance program and modification of dose constraints could be considered as a critically important component for ongoing trials of hypofractionation. Based on our findings, we initiated a multi-center retrospective study (KROG 18-04) and a prospective study (NCT03523078) to validate our findings. Introduction Breast reconstruction provides important psychosocial, cosmetic, and quality of life benefits ...

ConclusionsThe extent of surgery is not associated with improved survival in women with LBA, and patients may consider breast-conservation surgery. Adjuvant therapies are not associated with improved survival, with the exception of possible role of adjuvant chemotherapy in large primary tumors (5 cm or greater). Further clinical studies are needed to determine the impact of these treatments on local control, progression-free survival, and patients’ quality of life. Until then, the findings of our analysis will form basis for the multi-disciplinary discussion of management of women with L BA.
We report the results of a cohort of patients from a single center treated as part of the randomized phase-3 TARGIT-A trial.MethodsPatients ( ≥50 years) with cT1 cN0 cM0 and invasive ductal histology on biopsy were randomized between IORT with 20 Gy (arm-A) or postoperative whole-breast RT (WBRT) up to 56 Gy in 2 Gy fractions (arm-B). Postoperatively, patients in arm-A with multifocality, lymphovascular invasion, nodal invasion, extensive intraductal component, invasive lobular carcinoma, or resection margins
In conclusion, the present study showed that patients treated with BCS followed by radiotherapy had an improved outcome compared to radical mastectomy alone. Specifically, local control, distant control, and overall survival were significantly better using the conservative approach. Thus, as a result of the present study, physicians should encourage patients to receive BCS with radiotherapy rather than mastectomy, whenever it is medically feasible and appropriate.
