576 Background: BCS has been historically associated with a high re-excision rate, driven in part by the need of obtaining negative margins. The SSO-ASTRO consensus guideline on invasive margins, defined a negative margin as no ink on tumor. In this large population-based study of older breast cancer patients undergoing BCS for invasive breast cancer we evaluate the guideline impact on re-excision rates. Methods: Female patients diagnosed with stage I-II breast cancer between 2012-2015 were identified in the SEER-Medicare database. Patients were >66 years and underwent BCS. Patients treated with neoadjuvant chemotherapy were excluded. We defined the following time periods: pre-guideline (January 2012-September 2013); peri-guideline (October 2013-March 2014) and post-guideline (April 2014-December 2016). Re-excision was defined as a resection, BCS or mastectomy identified using ICD-9 or CPT codes between 4 and 90 days after initial BCS. Overall re-excision rates and 95%CI were calculated and groups compared using X2test. Within subgroups we calculated re-excision rates for the pre and post-guideline periods and report the relative percent change. Regression model evaluated the association between time periods and re-excision while adjusting for important covariates, risk ratios (RRs) and 95%CI are presented. Results: 17001 patients were included. 6762 of them had BCS in the pre, 1786 in the peri, and 8453 in the post-guideline periods. Overall 22.6% of the patients had a re-excision. The rate decreased from 24.8% pre-guideline to 20.3% post-guideline (P < 0.001). The relative change in re-excision varied according to region (Midwest 3-7.3%, Northeast -20%, West -16.5% and South -13.5%) Differences in the relative change according to race/ethnicity were also seen (Whites -19.2, Blacks -15.3% and Hispanics -9.9%). In the multivariable model, BCS in the post-guideline period was associated with a decreased risk of re-excision (RR = 0.83; 95%CI 0.79-0.88). Lobular histology was associated with a higher risk of re-excision (RR = 1.31; 95%CI 1.21-1.42); greater surgeon volume was associated with lower risk of re-excision (RR = 0.89; 95%CI 0.82-0.95). Conclusions: There has been a statistically significant decrease in the re-excision rate after BCS associated with the dissemination of the SSO-ASTRO consensus guideline on invasive margins. Our study confirms the impact that guidelines have modifying patterns or practice, reducing the frequency of unnecessary interventions.

91 Background: Due to improved screening for early breast cancer, the percentages of small and nonpalpable breast tumors have significantly increased during the last decades. After lumpectomy, re-excision rates of 32%-63% have been reported and the routine placement of localization needles is painful, time-consuming, and costly. In this study we investigated the value of intraoperative ultrasound (IOUS) in the hand of the breast surgeon as a fast and cheap method for potentially improving unacceptable re-excision rates. Methods: Between July 2001 and December 2010, in 773 of 1,195 breast cancer patients a breast-conserving treatment has been performed at the certified breast care center Vorarlberg (breast-conservation rate 64.7%). In 74.9% (579/773) of the tumors IOUS was performed, of which 44% were nonpalpable and 56% were insufficiently palpable, respectively. 7.5-10 MHz linear ultrasound probes were used by four breast surgeons in combination with intraoperative macroscopic resection margin assessment by the pathologist for prospective evaluation of definitive resection margin status over time. Furthermore, local recurrence rates were assessed. Results: During the study period, 579 of the included primary tumors were detected by IOUS. The metachronous re-excision rate was halved from 22% (30/135) in the period 2001-2003 to 11% (13/121) between 2008 and 2010. Between 2001 and 2010 we achieved a total re-excision rate of 13% (74/579). In 53% of re-excision specimens, no residual tumor was present, in 23% DCIS and in 24% invasive tumor was found, respectively. At a median follow-up of 56.4 months, a local recurrence rate of 1.7% was observed using our approach of IOUS combined with intraoperative margin assessment. Conclusions: IOUS in the hand of the breast surgeon proved to be a valuable, fast, and cheap method to improve metachronous re-excision rates in breast-conserving surgery. Patients can be spared the painful, costly, and time-consuming placement of a localization needle. Furthermore, tissue-sparing operations can be performed more easily and intraoperative specimen radiography can be avoided. The actual pathologic tumor size, however, is often being underestimated, especially regarding in situ cancers.

AbstractBackgroundThe aim of the study was to identify risk factors for positive surgical margins in breast-conserving surgery for breast cancer and to evaluate the influence of surgical experience in obtaining complete resection.MethodsAll lumpectomies for invasive breast carcinoma and ductal carcinoma in situ (DCIS) between April 2008 and March 2010 were selected from the database of a single institution. Re-excision rates for positive margins as well as patient and histopathologic tumor characteristics were analyzed. Surgical experience was staged by pairs made of Resident plus Specialist or Consultant. Two periods were defined. During period A, the majority of operations were performed by Residents under supervision of Specialist or Consultant. During period B, only palpable tumors were operated by Residents.ResultsThe global re-excision rate was 27% (50 of 183 patients). The presence of DCIS increased the risk for positive margins: 60% (nine of 15 patients) in the case of sole DCIS compared to 26% (41 of 160 patients) for invasive cancer (p = 0.005) and 35% (42 of 120 patients) in the case of peritumoral DCIS compared to 11% (seven of 62 patients) in the case of sole invasive cancer (p = 0.001). Re-excision rate decreased from 36% (23 of 64 patients) during period A to 23% (27 of 119 patients) during period B (p = 0.055). There was no significant difference between the surgical pairs.ConclusionIn our study, DCIS was the only risk factor for positive surgical margins. Breast-conserving surgery for non-palpable tumors should be performed by Specialists, however, palpable tumors can be safely operated by Residents under supervision.

Introduction: The aim of this pilot retrospective study is to evaluate the complication rate in patients after axillary dissection comparing preparation with harmonic scalpel vs traditional ligation technique, and to analyse risk factors for complications occurrence. Methods: 144 patients with 148 axillary dissections operated in a single centre between January 2014 and 2019 were included into the study. Axillary dissection was performed using harmonic scalpel in 73 and absorbable ligations in 70 cases. Results: Seroma formation was observed in 41 patients (56.2%) in the harmonic scalpel group and in 21 patients (30.0%) in the ligations group (p=0.003). The mean period from the surgery to drain removal was 4.0 days in the harmonic scalpel group and 3.0 days in the ligations group (p<0.001). The mean amount of the drained fluid after mastectomy was 300.9 ml in the harmonic scalpel group and 168.7 ml in the ligations group (p=0.005); after breast conserving surgery, it was 241.9 ml and 107.4 ml, respectively (p =0.023). Conclusion: In comparison with traditional ligations with absorbable material, axillary dissection using harmonic scalpel significantly increases the risk of postoperative seroma formation, prolongs the time from the surgery to drain removal, and increases the amount of drained fluid.ut any suspicion of nodal involvement, hemithyroidectomy is considered to be a sufficient procedure or the method of choice, respectively.

Introduction: Radiotherapy after Breast-Conserving Surgery (BCS) is a standard treatment for breast cancer. Currently, surgical clips are used to determine the tumour bed before radiotherapy planning. This study aimed to evaluate the migration of these clips on mammograms. Methods: The study was conducted on 121 females who were treated with radiotherapy after BCS at their first radiologic control examination 6 months after the end of treatment. MLO and CC views of all cases were evaluated regarding the clips. The distance between the surgical scar centre and the centre of the area covered by the clips was measured on both MLO and CC projections and recorded separately. This distance was determined as the clip displacement. A displacement ≤10 mm was recorded as no displacement. Results: The clips were out of the images and were not evaluated in 45 cases (37.2%) on CC and in 9 cases (7.4%) on MLO projections. There were no clip displacements in 37 (30.6%) cases on CC and in 43 (35.5%) cases on MLO views. The amount of displacement ranged from 11 to 56 mm with a mean of 24.38 mm on CC views, while on MLO projections, displacement ranged from 11 to 66 mm with a mean of 24.42 mm. Conclusion: A clip displacement of greater than 10 mm was found in 64.5% of cases on MLO views. Therefore, we believe that the reliability of these clips for accurate delineation of the tumour bed in radiotherapy planning is controversial and other methods must be added.
