Background: Accelerated partial breast irradiation (APBI) is defined as applying high doses of radiation with a shorter interval to the lumpectomy cavity in the setting of breast-conserving therapy for early-stage breast cancer. This treatment strategy is attractive to patients, and its utilization has increased during recent years because of the shorter treatment schedule, better cosmetic outcomes, and acceptable local control rates in selected patients undergoing breast-conserving therapy. Here we provide an overview of various APBI techniques in terms of clinical and cosmetic outcomes, quality of life, and cost of treatment. We also review the current guidelines for selecting suitable breast cancer patients for APBI strategy. Methods: A comprehensive literature search of PubMed between 1996 -2019 that was made was made for case series and randomized studies with at least 2 years of follow-up in term of clinical and cosmetic outcomes, quality of life, and treatment costs. Results: Technological advances have made various APBI modalities, including intracavitary and interstitial brachytherapy, intraoperative radiation therapy, and external-beam radiation therapy, more accessible in the community. Mature data from several randomized and prospective nonrandomized trials have contributed to the development of consensus guidelines for selecting the most appropriate candidates ABPI. Conclusion: APBI represent an attractive treatment option for appropriately selected patients with early breast cancer. Irrespective to various techniques used for APBI it is very important to select the most appropriate patient population according to reliable guidelines for this treatment strategy that could be non-inferiority to whole breast irradiation especially in high-volume radiation centers with long waiting lists and for patients who live far away from the radiotherapy centers.

Background: Postoperative breast abnormalities after breast conserving surgery or modified radical mastectomy are frequently overlooked and inaccurately assessed or reported using multidetector computed tomography (MDCT). These inaccurate results may have legal ramifications for the clinicians, cause patients avoidable anxiety, and lead to additional unnecessary diagnostic follow-up testing and costs. Methods: The patients with a history of breast cancer who had undergone breast-conserving surgery or modified radical mastectomy up to 6 months prior to undergoing a thoracic MDCT scan consented and enrolled in this study. These patients underwent a thoracic MDCT scan either because of respiratory or cardiac clinical symptoms or as part of breast cancer staging. Results: Forty women were included in this study. Different postoperative breast changes observed on thoracic MDCT scans including fibrous scar tissue, fat necrosis, seroma, abscess, hematoma, and recurrent and residual tumor were described. Conclusions: MDCT scans offer sufficient evidence in many postoperative cases to allow a confident diagnosis. General radiologists who review thoracic MDCT scans should know how to characterize breast lesions incidentally found on MDCT scans after breast surgeries. This information would enhance the value of the radiologist’s report for appropriate case management.
