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.

The Impact

98 Background: Recently, SSO/ASTRO published a consensus statement on margins for stage I and II invasive breast cancer treated with breast conserving surgery (BCS). We examined patients with ductal carcinoma in situ (DCIS) who underwent BCS to determine the effect of clinicopathologic and treatment factors including margin status, on locoregional recurrence (LRR), breast cancer-specific (BCSS) and overall survival (OS). Methods: From 2003-2010, we conducted a retrospective chart review of 253 consecutively diagnosed patients who underwent BCS for DCIS. Clincopathologic and treatment data were extracted. Margin status was defined by pathology reports with a negative margin as ≥ 2mm, close margin < 2mm and positive margin as tumor on ink. Clinicopathologic variables were tested using the Fisher’s exact test, Chi-square test, ANOVA F-test, and Kruskal-Wallis test. A Cox proportional - Hazards model was used to calculate the impact of these factors on LRR, BCSS and OS. Results: The median age of the cohort was 57 (range 21-89) and the majority were white (79%), ER+ (78%) and underwent radiation therapy (67%). Forty six percent took anti-endocrine therapy. Of 252 patients, 29% had close margins, 63% had negative margins and 7% had unknown margins. One patient had a positive margin and was alive without disease at last follow-up. At a median follow-up of 5 years, OS was 96%. Thirteen patients experienced a LRR with a median time to recurrence of 4.9 years (5 with close margins, 7 with negative, 1 unknown). On multivariate analysis, age and PR status were significant predictors of LRR. Patients with age >70 were more likely to recur than those age 50-69 (HR 6.7 95% CI (1.7-25.4) p= 0.005) as were patients with PR negative tumors (HR 5.7 95% CI (1.7-19.5) p= 0.005). Those patients who did not receive radiation therapy had a worse OS than those who did (HR 4.3 95%CI (1.5-12.6) p = 0.007). No variables were significant for BCSS. Conclusions: In this cohort of patients with DCIS treated with BCS, age and PR status were the only predictors of LRR. OS was only impacted by receipt of radiotherapy. Margin status was not predictive of LRR, BCSS or OS. This data suggests that routine re-excision for close margins may not be warranted.

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.

BACKGROUND: Breast conserving surgery followed by postoperative radiotherapy, as alternative to radical mastectomy, has been accepted as an optimal method for loco- regional treatment of the majority of women with early stage of breast carcinoma. The aim of the study was to evaluate the results of postoperative radiotherapy after breast conserving surgery in the Institute for oncology and radiology of Serbia. METHODS: During the 3-year period, 109 breast cancer patients with stage I and II were treated with postoperative radiotherapy after breast conserving surgery. Ninety- four patients underwent quadrantectomy with axillary node dissection, and 15 patients underwent only tumorectomy. After surgery all patients received postoperative radiotherapy to the whole breast with tumor dose 50 Gy in 15 fractions every second day. In 52 patients radiotherapy was given to the regional lymphatics with tumor dose 45 Gy in 15 fractions every second day. Twenty-eight patients received a booster dose (10 Gy) to the tumor bed. Adjuvant systemic therapy was administered depending on the nodal involvement and steroid receptors content: 17 patients received adjuvant chemotherapy (CMF or FAC), 18 received adjuvant hormonal therapy (tamoxifen or ovarian ablation), and 6 patients received both chemo- and hormonotherapy. RESULTS: After median follow-up period of 62 months, there was no evidence of loco- regional recurrence in anyone of patients. Distant metastases occurred in 7 patients (6.4%) with median disease free interval of 27.6 months. At last follow-up 91 patients (83.4%) were alive, 4 patients (3.7%) were dead of disease, and the same number was dead of other causes. The 5-year overall survival rate was 92.9% and disease-free survival rate was 92.7%. CONCLUSION: According to our results the combined surgery and radiotherapy approach provides good local control of early breast cancer patients. Postoperative radiotherapy after breast conserving surgery with or without adjuvant systemic therapy has important role in adjuvant treatment of early breast cancer.

611 Background: It is estimated that approximately 10% of all breast cancer patients will develop local recurrence (LR) at 10 years. Routine surveillance for detection of early breast cancer recurrence is widely performed despite lack of conclusive evidence for an improvement in patient quality of life or potential for cure. A number of historical studies evaluating the effectiveness of routine screening for LR following treatment for early-stage breast cancer have suggested that the diagnosis of LR is more frequent during a routine visit and occurring in asymptomatic patients. However, differentiating the method of detection is not often elucidated. In this study we evaluated the manner in which patients presented with an isolated LR in clinical practice. Methods: Our routine patient follow-up consists of physical exam and mammogram every 6 mos for the first 2 years following breast conserving surgery (BCS) and yearly thereafter. We queried our prospectively collected breast cancer database (1632 patients from July 1986 - July 2004) for patients with an isolated LR following BCS (n=59 (3.6%); two patients had bilateral LRs). Medical records were not available for three patients. Results: At a median follow-up of 45 mos (range: 5–122 mos) there were 58 evaluable LRs: 15 DCIS, 31 infiltrating ductal carcinoma (IDC), 6 infiltrating lobular (ILC), 2 mixed IDC/ILC, 3 invasive cancers NOS and 1 unknown. Patient presentation was as follows: 25 were diagnosed by self-exam, 28 on screening mammogram, 2 were diagnosed by physician (includes one referral), and 3 unknown. Mammogram detected recurrences were more frequent among patients with DCIS whereas self-detected recurrences were more common in patients with IDC (79% vs 33% and 21% vs 67%, respectively; P<0.2). Mean tumor size was larger in self-presentation (2.1 cm; range: 0.8–4.5 cm) than in mammogram detected group (1.6 cm; range 0.4–6 cm). Conclusions: These findings demonstrate the value of mammography as compared to patient detected LRs. Whether a survival advantage exists remains uncertain. Nevertheless routine physician examination in this setting is highly insensitive and its further utility must be considered when devising cost-effective strategies for surveillance of breast cancer patients. No significant financial relationships to disclose.

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.

Background: Breast cancer is one of the most common cancers in Bangladeshi women. Breast sacrificing treatment is still now the common practice in our country. Now a day’s breast conservative treatment is the standard treatment of breast cancer without compromising the survival. Objective: To observe local recurrence and distant metastasis free survival and overall survival of patients with breast cancer. Methods: Between January 1996 and December 2010, breast conserving treatment was carried out in 237 female patients with breast cancer in different Institutions of Bangladesh. Clinical staging was recorded by physical examination, relevant investigations as well as surgical records. Revised breast conserving surgery was carried out in those who had positive surgical margins or palpable disease. The patients with large but operable cancer or locally advanced cancer were treated by neoadjuvant chemotherapy followed by breast conserving surgery. Systemic adjuvant therapy (chemotherapy and or hormone therapy) and adjuvant radiotherapy were given in all patients. After completion of treatment, the patients were followed up with a standard protocol and data were compiled and analysed. Results: Among 237 patients who underwent breast conserving therapy 13 patients were excluded from the study for various reasons. Total 224 female patients with breast cancer who followed all the treatment schedules and attended for regular follow up were included in the study. They were between 22- 74 years of age, mean age 42.35 years; premenopausal 152 (68%). Sixty five percent (146 patients) was localized cancer (T1-2N0M0), 31.6% was regional cancer (T1-3N1M0), five cases were locally advanced stage (T4bN12M0) and two metastastatic cancer (T2-3N1M1).  All most all (98%) were Infiltrating duct cell carcinoma except four which were Intraductal carcinoma in situ (IDIS).  Estrogen and progesterone receptors were positive in 57% , HER2 positive (+++) in 24% of Patients. Lumpectomy/quandrentectomy with/without axillary clearance was done in 158 patients, revised breast conserving surgery in 53 cases, mastectomy in 8 cases and only biopsy done but no surgical treatment in five cases.Chemotherapy was given in 192 patients (86%); adjuvant 122 cases and neoadjuvant 70 cases. Hormone therapy in 182 patients. Radiotherapy: in 222 cases. Follow up period  was 4 years  to 19 years, median 10 years. Overall survival (OS) and disease free survival (DFS) was 84% and 70% respectively. Local recurrence occurred in 14(6%) cases and distant metastasis in 54 cases (24%). Conclusion: Breast conserving treatment was satisfactory for appropriate case selection and optimized therapy. Survival was no way worse than breast sacrificing treatment.
