Background: At present, the breast conserving therapy (BCT) is considered a treatment of choice for early-stage breast cancer. BCT aims to achieve complete tumor resection with adequate margin and offers better cosmetic outcome. Objective: To describe the experience with preoperative wire localization technique for early breast cancer and analysis of factors affecting positive margin status. Materials and Methods: The authors retrospectively reviewed 190 patients with 206 malignant breast lesions treated by breast conserving surgery (BCS) after mammographic- or ultrasound- guided wire localization. Patient age, lesion type such as mass, mass with calcifications, calcifications alone, and architectural distortion, BI-RADS assessment categories, size, location, modalities of imaging guidance, number of wires used, radiological and surgical margin status, pathological diagnosis, and tumor focality were recorded. Results: A 14.56% of positive surgical margin rate was observed. Mixed-effects logistic regression analysis showed larger lesion size was a significant predictor for positive surgical margin status at larger than 1.5 cm versus 1.0 cm or smaller (p=0.033). Conclusion: The present study data suggested that larger tumor size is the only significant predictor for positive surgical margin status. To deal with non-palpable large tumor, surgeon and radiologist should pay particular attention to achieve adequate surgical margin.

PURPOSE: To examine the relationship between pathologic margin status and outcome at 8 years after breast-conserving surgery and radiation therapy. PATIENTS AND METHODS: The study population comprised 533 patients with International Union Against Cancer/American Joint Committee on Cancer clinical stage I or II breast cancer who had assessable margins, who received at least 60 Gy to the primary tumor bed, and who had more than 8 years of potential follow-up. Each margin was scored (according to the presence of invasive or in situ disease that touched the inked surgical margin) as one of the following: negative, close, focally positive, or extensively positive. Outcome at 8 years was calculated using crude rates of first site of failure. A polychotomous logistic regression analysis was performed. Median follow-up time was 127 months. RESULTS: At 8 years, patients with close margins and those with negative margins both had a rate of local recurrence (LR) of 7%. Patients with extensively positive margins had an LR rate of 27%, whereas patients with focally positive margins had an intermediate rate of LR of 14%. In the polychotomous logistic regression model, margin status and the use of systemic therapy were the only two variables that had significant effects on the risk ratio of LR to remaining alive and free of disease. Among the 45 patients with focally positive margins who received systemic therapy, the crude LR rate was 7% at 8 years (95% confidence interval, 1% to 20%). CONCLUSION: Pathologic margin status and the use of adjuvant systemic therapy are the most important factors associated with LR among patients treated with breast-conserving surgery and radiation therapy.

e11538 Background: It is critical to obtain clear margins to minimize local recurrence after breast conserving surgery(BCS). When re-excisions are performed, there is often no residual disease in the new specimen, calling into question the need for re-excision(s) or mastectomy. The aim of the present study was to identify factors predicting a histologically positive re-excision specimen. Methods: Our prospective breast cancer database was queried for all invasive breast cancer patients who underwent a re-excision lumpectomy for either close or positive margins after an attempt at BCS. Close margins are defined as ≤ 2 mm for invasive carcinoma and presence of ductal carcinoma in situ(DCIS). Clinicopathologic features were correlated with the presence of residual disease in the re-excision specimen. Results: Between February 1997 and August 2008, 2054 patients with early breast cancer underwent surgical treatment in our breast unit. 939(45.7%) of them had BCS. In 543 patients(26.4%), re-excision required due to close margins on the permanent section analysis of their initial surgical specimens. 186 patients(34.3%) had previous excisional biopsy in other clinics. Median age of 543 patients was 50 years. In 290 patients(53.4%), mastectomy was performed due to positive surgical margin or poor cosmetic results. There were no residual tumors in re-excision(65.6 %) or mastectomy(42.4%) specimens of patients. The factors associated with tumor positive re-excision specimen were, age ≤50 years(p=0.044), lymphovascular invasion (p=0.029), multifocality(p<0.001), tumor size >2cm(p=0.008), presence of DCIS(p=0.018), focal margin positivity(p<0.001), DCIS at resection margin(p=0.008) and node positivity (p<0.001). Conclusions: Most of our patients with early breast cancer had unnecessary re-excisions or mastectomy to obtain clear surgical margins. In subset group of patients, re-excision or mastectomy may not be required. No significant financial relationships to disclose.

BACKGROUND: In patients with breast cancer for whom neoadjuvant chemotherapy (NAC) is planned, it is recommended to mark the primary tumor before treatment (planned surgery). However, surgeons may have to perform breast-conserving surgery on patients whose tumors are not marked (unplanned surgery). This study focused on the results obtained with planned and unplanned level II oncoplastic surgery (OPS) techniques applied to patients after NAC. METHODS: Patient groups who underwent planned, unplanned OPS and mastectomy after NAC were compared. Surgical margin status, re-operation and re-excision requirements, ipsilateral breast tumor recurrence (IBTR) and axillary recurrence rates recorded. Long-term local recurrence-free survival (LRFS), disease-free survival and overall survival were evaluated. RESULTS: There was no significant difference between the planned and unplanned OPS groups in terms of surgical margin status, re-excision requirement, and mastectomy rates. During an average follow-up period of 43 months, 5.3% and 4% of the patients in the planned OPS group developed IBTR and axillary recurrence, respectively, whereas these rates were 6.6% and 5.3% in the unplanned OPS group. In the mastectomy group, the rates of IBTR and axillary recurrence were found to be 4.1% and 3.8%, respectively. There was no significant difference between the three groups in terms of IBTR (p: 0.06) and axillary recurrence (p: 0.08) rates. CONCLUSION: Breast conserving surgery can be applied using level II OPS techniques with the post-NAC radiological examination and marking even if primary tumor marking is not done in the pre-NAC period.

Ductal Hyperplasia

Background. Negative margins are associated with a reduced risk of ipsilateral breast tumor recurrence (IBTR) in women with early stage breast cancer treated with breast conserving surgery (BCS). Not infrequently, atypical ductal hyperplasia (ADH) is reported as involving the margin of a BCS specimen, and there is no consensus among surgeons or pathologists on how to approach this diagnosis resulting in varied reexcision practices among breast surgeons. The purpose of this paper is to establish a reasonable approach to guide the treatment of ADH involving the margin after BCS for early stage breast cancer.Methods. the published literature was reviewed using the PubMed site from the US National Library of Medicine.Conclusions. ADH at the margin of a BCS specimen performed for early stage breast cancer is a controversial pathological diagnosis subject to large interobserver variability. There is not enough data evaluating this diagnosis to change current practice patterns; however, it is reasonable to consider reexcision for ADH involving a surgical margin, especially if it coexists with low grade DCIS. Further studies with longer followup and closer attention to ADH at the margin are needed to formulate treatment guidelines.

Background: Breast cancer is a common malignant tumor and treatment predominantly consists of surgery.  Modern society has increased the demands of women to have higher requirements for breast appearance and quality of life. Therefore, exploring effective measures to control or reduce the rate of loco-regional recurrence (LRR) after breast conserving surgery (BCS) is the main focus of this study.Methods: This cohort included 743 consecutive patients with invasive breast cancer, treated with BCS in 2 centers in Tehran, Iran between 2005 and 2010. The primary endpoint was the rate of loco-regional recurrence in a 5-year follow- up period. Authors also investigated the factors that could predict LRR after BCS.Results: The prevalence of LRR after BCS was 7.6% in a median follow-up of 56.9 months. The Median time to local recurrence was 20.45 months.  A correlation between follow-up outcome and age; histologic sub-type; surgical margin; number of positive nodes; complete pathologic response to neo-adjuvant chemotherapy; chemotherapy and hormone therapy was recognized. Surgical margin status, hormone therapy, histologic sub-type, age and Ki67 were shown to be significant risk factors for LRR in univariate analysis whereas surgical margin status emerged as an independent risk factor in multivariate analysis.Conclusions: Increased LRR was observed among those with higher ki67, aged under35, not receiving hormone therapy and with a surgical margin less than 2mm. These factors appeared to be risk factors for LRR after BCS, while, histologic grade, axillary nodal status, tumor size and biologic sub-type did not predict LRR after BCS.

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.
