Aim: This systematic review was conducted to compare the effectiveness of different accelerated partial breast irradiation (APBI) techniques for the treatment of breast cancer patients.
Background: Numerous (APBI) techniques are available for clinical practice.
Methods And Materials: Systematic review of randomized controlled trials of APBI versus whole breast irradiation (WBI). The data from APBI studies were extracted for the analyses. Indirect comparisons were used to compare different APBI techniques.
Results: Ten studies fulfilled the inclusion criteria. A total of 4343 patients were included, most of them with tumor stage T1-T2 and N0. Regarding APBI techniques, six trials used external beam radiation therapy; one intraoperative electrons; one intraoperative low-energy photons; one brachytherapy; and one external beam radiation therapy or brachytherapy. The indirect comparisons related to 5-years local control and 5-years overall survival were not significantly different between APBI techniques.
Conclusions: Based on indirect comparisons, no differences in clinical outcomes were observed among diverse APBI techniques in published clinical trials that formally compared WBI to APBI. However wide confidence intervals and high risk of inconsistency precluded a sound conclusion. Further head-to-head clinical trials comparing different APBI techniques are required to confirm our findings. Studies comparing different techniques using individual participant data and/or real-life data from population-based studies/registries could also provide more robust results.

Background: Intraoperative radiotherapy (IORT) is a convenient treatment techniques for patients with early-stage breast cancer. We aimed to compare the outcome of IORT to that of whole-breast external beam radiotherapy (EBRT) in highly selected breast cancer patients based on the 2023 American Society for Radiation Oncology (ASTRO) Clinical Practice Guideline for Partial Breast Irradiation (PBI).
Patients And Methods: We reviewed patients who underwent breast-conserving surgery (BCS) and received either IORT or EBRT for early-stage breast cancer between 2014 and 2019.

Background: To analyze in a prospective study the long-term safety and efficacy of 3-dimensional conformal radiotherapy (3D-CRT) to deliver accelerated partial breast irradiation (APBI) for Japanese women with early breast cancer.
Methods: Breast cancer patients with pathological tumor size ≤ 3 cm, age ≥ 20 years, lumpectomy with at least a 5 mm margin, and ≤ 3 positive axillary nodes were eligible. APBI was delivered by 3D-CRT at a dose of 38.

Purpose: This consensus statement of Indian Brachytherapy Society (IBS) aims to generate practical and reproducible guidelines allowing for direct implementation in the Indian scenario.
Material And Methods: IBS board of directors appointed a panel of physicians with expertise in breast cancer and, in particular, breast brachytherapy, to develop a consensus statement. First, a literature review on breast brachytherapy was conducted, focusing on randomized trials, prospective studies, and multi-institutional series.

Background: Over the past decade, the adoption of screening programs, digital mammography, and magnetic resonance imaging (MRI) has increased early-stage breast cancer diagnosis rates. Mortality rates have decreased due to early detection and improved treatments, including personalized therapies. Accelerated partial-breast irradiation (APBI) is emerging as a convenient and effective treatment for some patients, with studies exploring its preoperative use.

Purpose: Invasive lobular carcinoma (ILC) represents 10% to 15% of invasive breast cancers with limited representation among trials of accelerated partial breast irradiation (APBI). Contemporary guidelines advise against treating ILC with APBI given a paucity of supportive evidence. Here, we evaluated oncologic outcomes among patients with ILC treated with APBI.
