Modern radiotherapy techniques are designed to permit reduced irradiation of healthy tissue, resulting in a diminished risk of adverse effects and shortened recovery times. Several randomized studies have demonstrated the benefits of increased dosage to the tumor bed area in combination with whole breast irradiation (WBI). Conventional WBI treatment following breast-conserving procedures, which required 5-7 weeks of daily treatments, has been reduced to 3-4 weeks when using hyperfractionated regimens. The dosage administration improves local control, albeit with poorer cosmesis. The method of accelerated partial breast irradiation (APBI) shortens the treatment period whilst reducing the irradiated volume. APBI can be delivered using intraoperative radiation, brachytherapy, or external beam radiotherapy. Currently available data support the use of external beam partial breast irradiation in selected patients. Modern radiotherapy techniques make it possible to achieve favorable cosmesis in most patients undergoing immediate breast reconstruction surgery, and studies confirm that current methods of external beam radiation allow an acceptable coverage of target volumes both in the reconstructed breast and in the regional lymphatic nodes.

Breast-conserving surgery with adjuvant whole-breast irradiation has become the standard treatment for early breast cancer (EBC) patients. Partial breast irradiation, which targets only the postoperative cavity, has been established as an alternative to whole-breast therapy in selected patients. The treatment of elderly breast cancer patients differs from the therapeutic approach in younger ones, as elderly patients are prone to geriatric frailty and comorbid conditions, the incidence and severity of which increase with age. A review of the evidence, process, techniques, and results of accelerated partial breast irradiation (APBI) in elderly EBC patients, seems to indicate that APBI is an advisable postoperative approach in properly selected elderly EBC patients, combining advantages of a radical approach that minimizes the risk of undertreatment with efficient reduction of redundant irradiated volume, treatment toxicity, overall treatment time, staff workload, radiation technique workflow, patient transportation, and the potential for non-compliance. There is no "one size fits all" technique of APBI, the best technique always depending on willing patients, individual anatomy, performance status, patient frailty and comorbid conditions, and tumour location.
