BACKGROUND: Accelerated partial breast irradiation (APBI) was developed to address disadvantages of overall treatment time and potentially unnecessary radiation associated with whole breast irradiation (WBI). We report updated results of our single institution study using an external beam APBI regimen with a median follow-up of 8 years. METHODS: A total of 290 APBI patients with AJCC Stage 0-II breast cancer were compared with 290 WBI patients with matched tumor characteristics...

Intraoperative radiotherapy (IORT) is increasingly used worldwide. Breast cancer is the most rapidly growing indication for IORT, approaching 70-80% of cases in most centers. This report reviews the theoretical background and clinical use of IORT for primary and metastasized breast cancer. There are established applications such as tumor bed boost during breast-conserving surgery followed by whole breast radiotherapy or IORT as a form of accelerated partial-breast irradiation (APBI) for selected patients. Novel applications such as IORT for vertebral or brain metastases are presented as well as technological developments, widening the spectrum of potential clinical applications for IORT...

PURPOSE: We report the long-term results of phase II prospective study with accelerated partial breast irradiation (APBI) using interstitial multi-catheter high-dose-rate brachytherapy. METHODS: 240 patients received APBI (4Gy, twice daily; total dose 32Gy). RESULTS: Median follow-up was 96months. Recurrences in the treated breast developed in 8 patients (3.3%) at a median of 73months after APBI. The 5- and 10-year cumulative incidences were respectively, 1...

PURPOSE: To evaluate the impact of timing of adjuvant chemotherapy on wound healing and cosmetic outcome in women treated with accelerated partial breast irradiation (APBI). METHODS AND MATERIALS: Between August 2000 to December 2011, 224 women were treated with APBI using multicatheter interstitial high-dose-rate brachytherapy. Patients were treated to a dose of 34 Gy/10#/5-7 days with bid regimen. Systemic chemotherapy was administered as per the standard guidelines...

PURPOSE: Most dose calculations for HDR brachytherapy treatments are based on the AAPM-TG43 formalism. Because patient's anatomy, heterogeneities and applicator shielding are not considered, the dose calculation based on this formalism is inaccurate in some cases. Alternatively, Collapsed Cone (CC) methods as well as Monte Carlo (MC) algorithms belong to the model based dose calculation algorithms, which are expected to improve the accuracy of calculated dose distributions. In this work, the performance of a CC algorithm, ACE in Oncentra Brachy 4...

BACKGROUND AND PURPOSE: Accelerated partial breast irradiation (APBI) technology has theoretical advantages in comparison with traditional adjuvant radiation therapy (whole-breast irradiation; WBI) after breast-conserving surgery. However, published randomized controlled trials have shown inconsistent outcomes. Therefore, a comprehensive assessment of the effectiveness and safety of APBI technology is needed. RESULTS: A total of 7 studies of 7452 patients were included in this analysis...

PURPOSE: Regarding adjuvant radiation therapy making decision for elderly women, Albert (2013) published a nomogram predicting the mastectomy-free survival (MFS) rate with or without adjuvant irradiation. Based on this approach, we proposed to investigate the use of accelerated partial breast irradiation (APBI) vs. whole breast irradiation (WBI) or endocrine therapy alone in elderly low-risk breast cancer patients. METHODS AND MATERIALS: For each elderly woman treated by conserving surgery and APBI (multicatheter interstitial high-dose-rate brachytherapy), 5- and 10-year MFS rates were calculated...

Accelerated partial breast irradiation (APBI) is an increasingly utilized modality for early stage breast cancer as part of breast conservation therapy (BCT). There remains concern regarding local recurrence, requiring more frequent post-radiation surveillance imaging. The purpose of this study is to determine clinical significance of frequent surveillance in this perceived higher risk population. Patients treated at a community academic medical center from 2005 to 2013 with partial breast radiation were retrospectively identified...

PURPOSE: To report the clinical implementation of a novel external beam radiotherapy technique for accelerated partial breast irradiation treatments based on combined electron and photon modulated beams radiotherapy (MERT+IMRT) with conventional MLC. MATERIALS AND METHODS: A group of patients was selected to test the viability of the technique. The prescribed dose was 38.5Gy, following a hypofractionated schema, and the structures were defined following the NSABP-B39/RTOG-0413 protocol...

PURPOSE: To report our experience with full-dose 21 Gy IORT in early breast cancer patients after breast-conserving surgery to define most important selection factors. METHODS: Seven hundred and fifty eight patients, subjected to conserving surgery and IORT, were retrospectively analyzed evaluating most important clinical outcomes. RESULTS: Median follow up was 5.2 years. Results from Cox analyses defined 2 groups of patients, "suitable" (age > 50 years, non lobular histology, tumour size ≤ 2 cm, pN0 or pNmic, ki67 ≤ 20%, non triple negative receptor status and G1-G2) and "unsuitable" for IORT, with a higher rate of breast related events moving from "suitable" to "unsuitable" group...

PURPOSE: To describe early results of two cohorts of patients with low and intermediate risk of early breast cancer treated with accelerated partial breast irradiation (APBI) using different schedules of multicatheter brachytherapy. MATERIAL AND METHODS: Patients with early stage breast cancer after breast conserving surgery were enrolled for a prospective analysis. The APBI, using multicatheter brachytherapy, was delivered either eight times 4 Gy in five days with a planned total dose of 32 Gy, or seven times 5 Gy in four days with a planned total dose of 35 Gy...

Accelerated partial breast irradiation (APBI) provides an attractive alternative to whole breast irradiation (WBI) through normal tissue radiation exposure and reduced treatment duration. Intraoperative radiation therapy (IORT) is a form of APBI with the shortest time interval, as it delivers the entirety of a planned radiation course at the time of breast surgery. However, faster is not always better, and IORT has been met with healthy skepticism. Patients treated with IORT have an increased compliance and overall satisfaction when compared to patients treated with WBI...

PURPOSE: Little is known about long-term radiographic findings after treatment with accelerated partial breast irradiation (APBI). METHODS: Univariate and multivariate analysis of factors leading to formation and resolution of seroma were performed in patients treated with lumpectomy and APBI. RESULTS: Post-treatment images of 129 patients were reviewed by one radiologist. Median surgical excision volume was 108.9 cc (range 20.5-681.9). Primary mode of imaging was mammogram...

BACKGROUND: A shift towards less burdening and more patient friendly treatments for breast cancer is currently ongoing. In low-risk patients with early-stage disease, accelerated partial breast irradiation (APBI) is an alternative for whole breast irradiation following breast-conserving surgery. MRI-guided single dose ablative APBI has the potential to offer a minimally burdening, non-invasive treatment that could replace current breast-conserving therapy. METHODS: The ABLATIVE study is a prospective, single arm, multicenter study evaluating preoperative, single dose, ablative radiation treatment in patients with early-stage breast cancer...

BACKGROUND: Accelerated partial breast irradiation (APBI) represents a valid option for selected early breast cancer (BC). We recently published the 5-year results of the APBI-IMRT-Florence phase 3 randomised trial (NCT02104895), showing a very low rate of disease failure, with acute and early-late toxicity in favour of APBI. We present the early and 2-year follow-up health-related quality of life (HRQoL) results. METHODS: Eligible patients were women aged more than 40 years with early BC suitable for breast-conserving surgery...
