Introduction: Accelerated partial breast irradiation (APBI) with protons results in a very different acute effect profile than standard whole breast irradiation. We reviewed our initial experience with proton APBI and felt that a detailed description of these effects were needed to permit a common tool to compare experience with this developing technology. Methods: Sixty sequential patients treated with proton APBI on a prospective protocol were evaluated and 43 patients with a minimum six-month follow-up underwent detailed photographic and radiologic analysis...

Kaitlin M Christopherson, Benjamin D Smith
Radiation therapy is used in many cases of both early and late breast cancer. The authors examine the role of MR imaging as it pertains to radiotherapy planning and treatment approaches for patients with breast cancer. MR imaging can assist the radiation oncologist in determining the best radiation approach and in creating treatment planning volumes. MR imaging may be useful in the setting of accelerated partial breast irradiation. Radiation oncologists should attend to MR breast images, when obtained, to ensure that these imaging findings are taken into consideration when developing a radiation therapy plan...

The reduction in the burden related to treatment is becoming more and more important in modern oncology. Radiation therapy is a mainstay option in the postoperative setting for early breast cancer patients after breast-conserving surgery. Nowadays, different options are available to de-escalate radiotherapy in this scenario such as the use of hypofractionated whole-breast radiation, the selective delivery of the boost dose to the lumpectomy cavity, the introduction of accelerated partial breast irradiation and the omission of treatment in appropriately selected patients with low-risk features...

Brachytherapy was among the first methods of radiotherapy and has steadily continued to evolve. Here we present a brief review of the progression of dose calculation methods in brachytherapy to the current state-of-the art computerized methods for heterogeneity correction. We further review the origin and development of the BrachyVision (Varian Medical Systems, Inc., Palo Alto, CA) treatment planning system and evaluate dosimetric results from 12 patients implanted with the strut-assisted volumetric implant (SAVI) applicator (Cianna Medical, Aliso Viejo, CA) for accelerated partial breast irradiation (APBI)...

Background: Following breast-conserving surgery and post-operative 3D-conformal accelerated partial breast irradiation (APBI), suboptimal cosmetic results have been reported. Preoperative radiation delivery to the intact tumor enables better target visualization and treatment volume reduction. Single dose preoperative APBI has the potential to improve toxicity profiles, reduce treatment burden and enable in vivo exploration of breast cancer radiogenomics. Purpose: Develop practical guidelines for single dose external beam preoperative APBI...

BACKGROUND: Local recurrences after breast conserving treatment are mainly close to the original tumor site, and as such shorter fractionation strategies focused on and nearest mammary gland, i.e. accelerated partial breast irradiation (APBI), have been developed. Stereotactic APBI has been attempted, although there is little experience using CyberKnife (CK) for early breast cancer. METHODS: This pilot study was designed to assess the feasibility of CK-APBI on 20 evaluable patients of 29 eligible, followed for 2 years...

The conventionally fractionated partial breast irradiation (PBI) IMPORT LOW trial represents the perfect example of how an adequate selection of patients led to a minimal local relapse rate for patients. Coles and colleagues, demonstrated a 5-year non-inferiority local relapse rate for PBI compared to standard whole breast irradiation, together with a significant reduction in terms of breast toxicity using a conventional radiation technique implementable worldwide. Most of enrolled patients had early stage node negative, grade1-2, oestrogen receptor positive, human epidermal growth factor receptor 2 negative tumours...

REVIEW
Nisha Ohri, Bruce G Haffty
Adjuvant whole-breast irradiation (WBI) after lumpectomy has been an established standard of care for decades. Standard-fractionation WBI delivered over 5 to 7 weeks can achieve durable tumor control with low toxicity but can be inconvenient for patients and cost ineffective. Hypofractionated WBI can be completed in 3 to 4 weeks and, based on long-term randomized data, is the preferred standard of care in select patients. Accelerated partial-breast irradiation can be delivered using even shorter treatment regimens...
