This study aimed to investigate type of loco-regional treatment received, associated treatment factors and mortality outcomes in New Zealand women with early-stage breast cancer who were eligible for breast conserving surgery (BCS). This is a retrospective analysis of prospectively collected data from the Auckland and Waikato Breast Cancer Registers and involves 6972 women who were diagnosed with early-stage primary breast cancer (I-IIIa) between 1 January 2000 and 31 July 2015, were eligible for BCS and had received one of four loco-regional treatments: breast conserving surgery (BCS), BCS followed by radiotherapy (BCS + RT), mastectomy (MTX) or MTX followed by radiotherapy (MTX + RT), as their primary cancer treatment. About 66.1% of women received BCS + RT, 8.4% received BCS only, 21.6% received MTX alone and 3.9% received MTX + RT. Logistic regression analysis was used to identify demographic and clinical factors associated with the receipt of the BCS + RT (standard treatment). Differences in the uptake of BCS + RT were present across patient demographic and clinical factors. BCS + RT was less likely amongst patients who were older (75+ years old), were of Asian ethnicity, resided in impoverished areas or areas within the Auckland region and were treated in a public healthcare facility. Additionally, BCS + RT was less likely among patients diagnosed symptomatically, diagnosed during 2000–2004, had an unknown tumour grade, negative/unknown oestrogen and progesterone receptor status or tumour sizes ≥ 20 mm, ≤50 mm and had nodal involvement. Competing risk regression analysis was undertaken to estimate the breast cancer-specific mortality associated with each of the four loco-regional treatments received. Over a median follow-up of 8.8 years, women who received MTX alone had a higher risk of breast cancer-specific mortality (adjusted hazard ratio: 1.38, 95% confidence interval (CI): 1.05–1.82) compared to women who received BCS + RT. MTX + RT and BCS alone did not have any statistically different risk of mortality when compared to BCS + RT. Further inquiry is needed as to any advantages BCS + RT may have over MTX alternatives.

Breast Irradiation

Breast-conserving therapy has been established as a standard treatment for women with early-stage breast cancer. Whole-breast irradiation has traditionally been utilized to consolidate local therapy following conservative surgery. Recently, the need for whole-breast irradiation after breast-conserving surgery has become controversial, with some investigators advocating accelerated partial breast irradiation as an alternative. Accelerated partial breast irradiation is delivered over a shorter period and only to a portion of the breast. This review will examine the emerging role of accelerated partial breast irradiation in the treatment of early-stage breast cancer and review the biologic rationale for, techniques of, and limitations of partial breast irradiation following breast-conserving surgery.

Adjuvant Surgery

According to the National Cancer Comprehensive Network guidelines patients with breast tumours ≤1 cm should be offered systemic therapy. Multiple studies, however, have demonstrated no survival advantage between giving chemotherapy before (neoadjuvant) or after (adjuvant) surgery. There are, however, certain benefits that can be derived from patients who undergo neoadjuvant chemotherapy. Such benefits include better stratification of the patient's prognosis based on tumour and nodal response, and converting patients from mastectomy-only candidates to breast-conserving surgery candidates. Due to these advantages, many patients with early-stage breast cancer will undergo neoadjuvant chemotherapy and the surgical issues must be considered for patients who are treated in such a manner to guarantee optimal outcomes. Issues that will be discussed are the surgical preoperative evaluation, extent and timing of local resection of both the breast and regional nodes and finally, the potential future effects of this multi-modality therapy.
