Abstract
Myofibroblastoma (MFB) is a rare but benign mesenchymal tumor most commonly appearing within breast tissue. Most cases of MFB occur in postmenopausal women and are treated by surgical excision. The diagnosis of MFB is made through immunohistochemical (IHC) analysis, with the most common biomarkers being CD34+, desmin+, smooth muscle actin+, and vimentin+. In this article, we describe a case of an MFB in a premenopausal female with variance from classic IHC findings. We also performed a systemic review of the MFB of the breast. The systemic review compiles the most common IHC findings of MFB, patient demographics, treatment methods, lesion size, and the presence or absence of pain associated with the lesion. As MFB can share many features with other breast lesions, including potentially malignant ones, this article sought to underline the most common IHC findings and characteristics of MFB to aid in the proper diagnosis of MFB.

Abstract
BACKGROUND Anesthesia methods in oncologic breast surgery have evolved with less invasive practices. The aims of this study were primarily to examine trends in anesthesia type used during lumpectomy. METHODS We analyzed lumpectomy procedures from 2005 to 2019 using the NSQIP database. Upon defining the nadir in general anesthesia (GA) and peak in monitored anesthesia care (MAC) use as 2007, we compared patient characteristics and complications in the 2007 versus 2019 GA and MAC cohorts. Multivariable logistic regression was used to examine associations with receipt of GA. RESULTS Of 253 545 lumpectomy patients, 191 773 (75.6%) received GA and 61 772 (24.4%) received MAC. From 2005 to 2019, GA rates increased from 66.7% to 82.5%, while MAC rates decreased from 33.3% to 17.5%. More GA patients were obese and American Society of Anesthesiologists class 3. Over time, age and body mass index (BMI) increased in both GA and MAC cohorts. Odds of receiving GA increased over time, and predictors included concurrent axillary lymph node dissection (p < 0.0001) or sentinel lymph node biopsy (p < 0.0001). CONCLUSIONS We demonstrate increasing use of GA over time for lumpectomy, which may be related to aging lumpectomy patient population with higher BMIs. We also find a strong association between use of GA and concurrent lymph node procedures.

Abstract
Introduction Partial breast irradiation (PBI) has increased in utilization, with the postoperative lumpectomy cavity and clips used to guide target volumes. The ideal timing to perform computed tomography (CT)-based treatment planning for this technique is unclear. Prior studies have examined change in volume over time from surgery but not the effect of patient characteristics on lumpectomy cavity volume. We sought to investigate patient and clinical factors that may contribute to larger postsurgical lumpectomy cavities and therefore predict for larger PBI volumes. Methods A total of 351 consecutive women with invasive or in situ breast cancer underwent planning CT after breast-conserving surgery at a single institution during 2019 and 2020. Lumpectomy cavities were contoured, and volume was retrospectively computed using the treatment planning system. Univariate and multivariate analyses were performed to evaluate the associations between lumpectomy cavity volume and patient and clinical factors. Results Median age was 61.0 years (range, 30-91), 23.9% of patients were Black people, 52.1% had hypertension, the median body mass index (BMI) was 30.4 kg/m², 11.4% received neoadjuvant chemotherapy, 32.5% were treated prone, mean interval from surgery to CT simulation was 54.1 days ± 45.9, and mean lumpectomy cavity volume was 42.2 cm3 ± 52.0. Longer interval from surgery was significantly associated with smaller lumpectomy cavity volume on univariate analysis, p = 0.048. Race, hypertension, BMI, the receipt of neoadjuvant chemotherapy, and prone position remained significant on multivariate analysis (p < 0.05 for all). Prone position vs. supine, higher BMI, the receipt of neoadjuvant chemotherapy, the presence of hypertension, and race (Black people vs. White people) were associated with larger mean lumpectomy cavity volume. Discussion These data may be used to select patients for which longer time to simulation may result in smaller lumpectomy cavity volumes and therefore smaller PBI target volumes. Racial disparity in cavity size is not explained by known confounders and may reflect unmeasured systemic determinants of health. Larger datasets and prospective evaluation would be ideal to confirm these hypotheses.

Abstract
Introduction Breast-conserving surgery (BCS) followed by adjuvant radiotherapy has similar overall survival compared to mastectomy but is associated with higher rates of local recurrence. Positive surgical margins in BCS are the most important predictor of local recurrence. The aim of our study was to assess the risk factors associated with positive margins in women undergoing BCS for breast cancer in order to inform our clinical practice and minimize re-operation rates. Methods Patients with a diagnosis of breast cancer who underwent BCS from January 2013 to January 2021 were identified from our pathology database and included in the study. All patients underwent a lumpectomy with the removal of additional shaved cavity margins. Statistical analysis was used to assess the effect of patient clinical and pathological risk factors on the rate of positive margins. Results One hundred and twenty patients underwent BCS for breast cancer. Twenty-four percent of patients had positive margins. Of the 29 patients that underwent subsequent re-excisions, only 13 (45%) had residual disease in the re-excision specimen. In younger patients, tumors localized in lower quadrants and the presence of extensive intraductal component within invasive breast cancer increased the risk of positive margins. In addition, positive margins were encountered more significantly in patients with ductal carcinoma in situ (DCIS) compared to invasive tumors. Multivariate analysis showed that DCIS and young age were the only factors independently associated with positive margins. Conclusion DCIS and younger patients have a higher rate of positive margins during BCS than invasive breast cancer. For such patients at higher risk of positive margins, excision of cavity shave margins and intraoperative inking may be done to lower positive margin rates. Preoperative review of breast imaging, core biopsies, and counseling of patients about the likelihood of positive margins is important.

Abstract
An 81-year-old female patient underwent a screening mammogram one year after completing treatment for right-sided estrogen receptor (ER)/progesterone receptor (PR)-negative ductal carcinoma in situ (DCIS). A new 1-cm mass was noted in the contralateral breast. Ultrasound and percutaneous core needle biopsy results were suggestive of an atypical papillary lesion. An excisional biopsy was performed, and the final pathology was consistent with a benign adenomyoepithelioma (AME). Surgical resection was considered her definitive treatment. AME of the breast is a rare clinical entity, with only a handful of case reports and case series available. In this case report, we review common clinical and radiologic presentations, methods of diagnosis, and recommendations for management based on current literature. The presence of an AME in the background of a previous or synchronous breast malignancy occurs in a very small percentage of cases. On review of available literature, we identified other cases with a past or current history of breast malignancy.

Abstract
Purpose This study aimed to compare the adverse reactions of conventional-dose and hypofractionated dose of proton therapy for breast cancer.
Materials and methods Breast cancer patients treated with proton radiotherapy in conventional-dose or hypofractionated dose were studied retrospectively.
Result From January 2017 to December 2019, our center treated 50 patients following lumpectomy with proton radiotherapy. According to the AJCC 8th Edition standard, there were stage I in 26 patients, stage II in 22 patients, and stage III in 2 patients. A total of 14 patients received intensity-modulated proton therapy at a dose of 50 Gy in 25 fractions, followed by a 10 Gy 4 fractionated boost to the lumpectomy cavity, while 36 received 40.05 Gy in 15 fractions, simultaneous integrated boost (SIB) 48 Gy to the lumpectomy cavity. Median follow-up time for 40.05 Gy group was 35.6 months (15–43 months). Median follow-up time for 50 Gy group was 46.8 months (36–68 months). For acute toxicity, the grade 1 and 2 radiodermatitis in conventional-dose group were 35.7% and 57.1%, respectively. In hypofractionated dose group, the grade 1 and 2 radiodermatitis were 91.7% and 8.3%, respectively. The radiodermatitis is hypofractionneted dose better than conventional-dose significantly. Grade 1 radiation-induced esophagitis in conventional-dose group and hypofractionated dose group were 85.71% and 60%, respectively. For late toxicity, no patients developed radiation-induced pneumonitis and rib fracture in conventional-dose group. Three patients presented grade 1 pneumonitis; one patient presented graded 2 pneumonitides and two patients presented rib fracture in hypofractionated dose group. One presented hypothyroidism in hypofractionated dose group. All patients were satisfied with breast shape. The one- and two-year OS and DFS for conventional-dose group were 100 and 100; 100 and 92.9%, respectively. The one- and two-year OS and DFS for hypofractionated dose group were 100 and 100; 100 and 100%, respectively. Conclusion Proton radiation therapy can significantly reduce the normal tissue dose in breast cancer patients' hearts, lungs, and other organs. Hypofractionated proton therapy shortens the treatment course with mild radiation-related adverse effects, and has a better effect on addressing the acute adverse reactions than conventional proton radiotherapy.

Abstract
Due to its rarity, literature pertaining to radiation-associated breast angiosarcoma (RAS) remains sparse, with most studies focusing on retrospective review. Of more significant concern is the ambiguity of screening recommendations and modalities used to detect RAS, with current guidelines focusing on yearly mammographic imaging for women who underwent lumpectomy with radiation. Unfortunately, routine post-cancer screening has demonstrated low sensitivity in detecting RAS, often mistaking it for benign changes in roughly half of cases. We present an 83-year-old woman initially diagnosed with stage 1 invasive ductal carcinoma of the left breast who underwent a lumpectomy followed by radiation with 6040 cGy. Five years after her initial diagnosis, the patient noticed a suspicious lesion which then led her to undergo multiple modalities of imaging that described benign features. After continued concern, a biopsy was taken that demonstrated RAS of the left breast within the irradiated site. The patient underwent further radiation and declined surgical intervention. Routine screening with mammography and ultrasonography following breast radiation treatment are not sensitive modalities in detecting RAS. High-risk patient groups treated with greater than 0.5 Gy of radiation with concerning physical features 2-10 years after treatment should undergo MRI with biopsy at the initial concern to rule out angiosarcoma. Benign findings on imaging with patients in these groups should also consider biopsy.

Abstract
OBJECTIVES Neurological complications including pain are common after treatment for breast cancer. This prospective study investigated the symptoms, intensity and interference of chemotherapy-induced peripheral neuro-pathy. (CIPN) in the feet and hands compared to surgery- and radiation-induced neuropathy in the breast and upper arm. METHODS Consecutive patients referred to surgery for breast cancer were included in a prospective study and completed a questionnaire at baseline and a follow-up questionnaire and interview after one year. CIPN was assessed with the CIPN20 questionnaire and the Michigan Neuropathy Screening Instrument questionnaire (MNSIq). Pain intensity was rated on a numeric rating scale (NRS, 0-10). RESULTS In total 144 patients were included, of which 73 received chemotherapy. At one-year follow-up, symptoms of polyneuropathy were more common in patients treated with chemotherapy. Tingling or numbness in the feet in those treated/not treated with chemotherapy was reported by 44 (62%) and 15 (21%), respectively. Pain was present in 22 (30%) and 10 (14%), respectively. Pain in the area of surgery was reported by 66 (46%). Although less common, pain in the feet in those treated with chemotherapy was rated as more intense and with more daily life interference than pain in the surgical area (NRS 5.5 (SD 1.9) vs. 3.1 (SD 1.9). CONCLUSIONS Neurological complications including pain following surgery and chemotherapy represent a burden to breast cancer survivors. In those who had received chemotherapy, pain in the feet was less common than pain in the surgical area, but pain in the feet was more intense and had a higher interference with daily life. Our study emphasizes the need for either baseline data or a control population for improved estimation of the presence and severity of CIPN and pain from questionnaires.

Abstract
Background Breast conserving therapy (BCT) is the mainstay therapy in patients with early breast cancer and selected patients with locally advanced breast cancer. No formal audit has been performed on BCT at our institution. Objectives To determine the incidence and risk factors for ipsilateral breast tumour recurrence (IBTR). Study the imaging features of IBTR. Determine adherence to the proposed annual mammographic surveillance schedule. Method Clinical, radiological and histopathological records of patients who underwent BCT from 01 January 2011 to 31 December 2015 were reviewed. Patients were followed up for at least 5 years. Results Ninety-two patients were included in the study with a mean age of 54.3 years. Eighty of the 92 (87.0%) patients were imaged within 1-year post-BCT. Ipsilateral breast tumour recurrence was 6/92 (6.5%) with mean time to IBTR of 34.4 months. One of the 92 (1.0%) patients had a contralateral metachronous recurrence with no IBTR and 11/92 (12.0%) had distant metastases only. Pathological tumour size and extent (pT2) (68.5%) and pathological lymph node (pN0) (65.2%) were the most common locoregional staging. Infiltrating ductal carcinoma was the most common histological type (88%). Age < 35 years was associated with breast cancer recurrence (p < 0.01). Imaging findings of recurrence were microcalcification (odds ratio [OR]: 4), asymmetric density (OR: 4) and skin thickening (OR: 2.5). Conclusion The occurrence of IBTR following BCT in our unit is acceptable and comparable to local and international units. The accuracy of assessing the post-BCT breast for IBTR is in keeping with international standards. Contribution Improved radiological imaging interpretation of the post-BCT breast.

Abstract
Stereotactic vacuum-assisted breast biopsy (VABB) system is generally used to perform breast biopsies after identifying suspicious lesions that are occult on ultrasound. In this case, we used an 8-Gauge VABB to retrieve a needle point retained in the outer-lower quadrant of the right breast of a patient previously treated with lumpectomy. The use of stereotactic VABB system in this specific clinical setting has been never described before and resulted minimally invasive and perfectly suitable for correct localisation and retrieval of the 3-mm needle point; moreover, it may be easily reproduced elsewhere.

Abstract
OBJECTIVE During breast conserving surgery (BCS), magnetic resonance (MR) images aligned to accurately display intraoperative lesion locations can offer improved understanding of tumor extent and position relative to breast anatomy. Unfortunately, even under consistent supine conditions, soft tissue deformation compromises image-to-physical alignment and results in positional errors. METHODS A finite element inverse modeling technique has been developed to nonrigidly register preoperative supine MR imaging data to the surgical scene for improved localization accuracy during surgery. Registration is driven using sparse data compatible with acquisition during BCS, including corresponding surface fiducials, sparse chest wall contours, and the intra-fiducial skin surface. Deformation predictions were evaluated at surface fiducial locations and subsurface tissue features that were expertly identified and tracked. Among n = 7 different human subjects, an average of 22 ± 3 distributed subsurface targets were analyzed in each breast volume. RESULTS The average target registration error (TRE) decreased significantly when comparing rigid registration to this nonrigid approach (10.4 ± 2.3 mm vs 6.3 ± 1.4 mm TRE, respectively). When including a single subsurface feature as additional input data, the TRE significantly improved further (4.2 ± 1.0 mm TRE), and in a region of interest within 15 mm of a mock biopsy clip TRE was 3.9 ± 0.9 mm. CONCLUSION These results demonstrate accurate breast deformation estimates based on sparse-data-driven model predictions. SIGNIFICANCE The data suggest that a computational imaging approach can account for image-to-surgery shape changes to enhance surgical guidance during BCS.

Abstract
Purpose Breast conserving surgery (BCS) is a common procedure for early-stage breast cancer patients. Supine preoperative magnetic resonance (MR) breast imaging for visualizing tumor location and extent, while not standard for procedural guidance, is being explored since it more closely represents the surgical presentation compared to conventional diagnostic imaging positions. Despite this preoperative imaging position, deformation is still present between the supine imaging and surgical state. As a result, a fast and accurate image-to-physical registration approach is needed to realize image-guided breast surgery. Approach In this study, three registration methods were investigated on healthy volunteers' breasts ( n = 11 ) with the supine arm-down position simulating preoperative imaging and supine arm-up position simulating intraoperative presentation. The registration methods included (1) point-based rigid registration using synthetic fiducials, (2) nonrigid biomechanical model-based registration using sparse data, and (3) a data-dense three-dimensional diffeomorphic image-based registration from the Advanced Normalization Tools (ANTs) repository. Additionally, deformation metrics (volume change and anisotropy) were calculated from the ANTs deformation field to better understand breast material mechanics. Results The average target registration errors (TRE) were 10.4 ± 2.3 , 6.4 ± 1.5 , and 2.8 ± 1.3 mm (mean ± standard deviation) and the average fiducial registration errors (FRE) were 7.8 ± 1.7 , 2.5 ± 1.1 , and 3.1 ± 1.1 mm for the point-based rigid, nonrigid biomechanical, and ANTs registrations, respectively. The mechanics-based deformation metrics revealed an overall anisotropic tissue behavior and a statistically significant difference in volume change between glandular and adipose tissue, suggesting that nonrigid modeling methods may be improved by incorporating material heterogeneity and anisotropy. Conclusions Overall, registration accuracy significantly improved with increasingly flexible and data-dense registration methods. Analysis of these outcomes may inform the future development of image guidance systems for lumpectomy procedures.

Abstract
BACKGROUND AND OBJECTIVES Breast-conserving surgery (BCS) is followed by reoperations in approximately 25%. Reoperations lead to an increased risk of infection and wound healing problems as well as a worse cosmetic outcome. Several technical approaches for an intraoperative margin assessment to decrease the reoperation rate are under evaluation, some of them are still experimental. METHODS A prospective single-arm post-marketing study with 60 patients undergoing BCS for ductal carcinoma in situ (DCIS) and invasive breast cancer was conducted. The specimen was intraoperatively examined by the ClearSight™ system, a mobile magnetic resonance imaging system that is based on a diffusion-weighted imaging protocol. However, the results were blinded to the surgeon. RESULTS The ClearSight™ system was performed for both ductal and lobular breast cancer and DCIS, with a sensitivity of 0.80 (95% confidence interval [CI]: 0.44-0.96) and a specificity of 0.84 (95% CI 0.72-0.92), with an overall diagnostic accuracy of 80%. CONCLUSION Had the ClearSight™ been known to the surgeon intraoperatively, the reoperation rate would have been reduced by 83% for invasive carcinoma, from 10% to 2%, and 50% for DCIS, from 30% to 15% reoperations. A trial designed to examine the impact on reoperation rates is currently ongoing.

Breast conserving surgery (BCS) is a common procedure for early-stage breast cancer patients. Supine preoperative magnetic resonance (MR) breast imaging for visualizing tumor location and extent, while not standard for procedural guidance, more closely represents the surgical presentation compared to conventional diagnostic pendant positioning.

Abstract
Breast cancer is the most common cancer in women, and surgical resection is standard of care for the majority of breast cancer patients. Unfortunately, current reoperation rates are 10-29%. Uncertainty in lesion localization is one of the main factors contributing to these high reoperation rates. This work uses the linearized iterative boundary reconstruction approach to model patient breast deformation due to abduction of the ipsilateral arm. A preoperative supine magnetic resonance (MR) image was obtained with the patient's arms down near the torso. A mock intraoperative breast shape was measured from a supine MR image obtained with the patient's arm up near the head. Sparse data was subsampled from the full volumetric image to represent realistic intraoperative data collection: surface fiducial points, the intra-fiducial skin surface, and the chest wall as measured with 7 tracked ultrasound images. The deformed preoperative arm-down data was compared to the ground truth arm-up data. From rigid registration to model correction the tumor centroid distance improves from 7.3 mm to 3.3 mm, average surface fiducial error across 9 synthetic fiducials and the nipple improves from 7.4 ± 2.2 to 1.3 ± 0.7, and average subsurface error across 14 corresponding features improves from 6.2 ± 1.4 mm to 3.5 ± 1.1 mm. Using preoperative supine MR imaging and sparse data in the deformed position, this modeling framework can correct for breast shape changes between imaging and surgery to more accurately predict intraoperative position of the tumor as well as 10 surface fiducials and 14 subsurface features.

Abstract
SUMMARY Obstructive sleep apnea (OSA) is a condition of intermittent nocturnal upper airway obstruction. OSA increases sympathetic drive which may result in clinical and biochemical features suggestive of pheochromocytoma. We present the case of a 65-year-old male with a 2.9-cm left adrenal incidentaloma on CT, hypertension, symptoms of headache, anxiety and diaphoresis, and persistently elevated 24-h urine norepinephrine (initially 818 nmol/day (89-470)) and normetanephrine (initially 11.2 µmol/day (0.6-2.7)). He was started on prazosin and underwent left adrenalectomy. Pathology revealed an adrenal corticoadenoma with no evidence of pheochromocytoma. Over the next 2 years, urine norepinephrine and normetanephrine remained significantly elevated with no MIBG avid disease. Years later, he was diagnosed with severe OSA and treated with continuous positive airway pressure. Urine testing done once OSA was well controlled revealed complete normalization of urine norepinephrine and normetanephrine with substantial symptom improvement. It was concluded that the patient never had a pheochromocytoma but rather an adrenal adenoma with biochemistry and symptoms suggestive of pheochromocytoma due to untreated severe OSA. Pseudo-pheochromocytoma is a rare presentation of OSA and should be considered on the differential of elevated urine catecholamines and metanephrines in the right clinical setting. LEARNING POINTS Obstructive sleep apnea (OSA) is a common condition among adults. OSA may rarely present as pseudo-pheochromocytoma with symptoms of pallor, palpitations, perspiration, headache, or anxiety. OSA should be considered on the differential of elevated urine catecholamines and metanephrines, especially in patients with negative metaiodobenzylguanidine (MIBG) scan results.

Abstract
Idiopathic granulomatous mastitis (IMD) is a chronic benign inflammatory disease of the breast which can mimic breast cancer. It is more common in young women of childbearing age and poses a challenge in diagnosis of inflammatory breast tumor. We report the case of a 26-year-old female patient who presented with inflammatory breast. Clinical examination showed apyretic patient with edematized and painless irregular smooth mass in the left breast measuring 4 cm surmounted by crusts and multiples fistulizing scars discharging pus by applying pressure, with mobile ipsilateral axillary adenopathy. The remainder of the physical examination showed inflammatory erythematous patches on both legs. A mammogram plus breast ultrasound was performed followed by biopsy that objectified fibrous mastopathy. Lumpectomy was performed due to the persistence of symptoms. Anatomopathological examination objectified granulomatous mastitis. Etiological research didn't identify a clear cause. Corticotherapy associated with antibiotic therapy was started with complete regression of symptoms after two months.

Abstract
Background Annually about 280,000 women are diagnosed with breast cancer. Treatment options depend on age, comorbidities, tumor stage, grade, size, and other factors. Often, patients must decide between two surgical treatment options: mastectomy or lumpectomy-with-radiation herein simply called a lumpectomy. Since both offer similar survival outcomes, the choice ultimately is the patient’s. However, most rely on inputs from doctors, family, friends, personal research, and other actions. We believe decision-making processes for future patients will be aided if experiences of prior breast cancer survivors are known. This study’s aim is to provide such information. Methods Feedback from prior breast cancer survivors was obtained using a 19-question survey distributed online to multiple breast cancer support groups. It focused on issues relevant to choosing between the two surgical options including, post-surgical complications, breast reconstruction, chronic pain, cosmetics, and surgery-choice satisfaction. Results Respondents (N=1606) had a median age of 49 years (range 26 to 88 years) and had a median body mass index (BMI) of 26.6 Kg/m2. There were 978 mastectomy patients (60.9%) and 628 lumpectomy patients (39.1%). With regard to post-surgical reconstruction, 64.2% of mastectomy respondents and 13.5% of lumpectomy respondents decided to undergo breast cancer reconstruction following breast cancer surgery. Almost all (99.8%) of lumpectomy respondents had radiation side-effects; with skin irritation and thickening and chest wall tenderness being the most common. Among mastectomy patients, 94.3% had one or more complications; loss-or-changes in nipple or breast sensation, uneven breasts, chest wall tenderness, and breast swelling were the most common complications. Post-surgical pain lasting six months or more was experienced by a smaller percentage of mastectomy vs. lumpectomy patients (64.1% vs. 78%, p <0.00001). Mastectomy patients were also less likely to have pain that was persistent and present up to the time of the survey (35.4% vs. 46.0%, p=0.0002). With respect to cosmetic outcomes, mastectomy patients vs. lumpectomy patients were less likely to be either satisfied or very satisfied (52.2% vs. 62.7%, p=0.00004). Overall satisfaction of surgical treatment was 70.9% for mastectomy patients and 68.6% for lumpectomy patients. Conclusion Based on the experiences of these breast cancer survivors, mastectomy is associated with less chronic pain frequency and lower incidence of post-surgical side effects compared to lumpectomy. However, mastectomy is associated with lower cosmetic satisfaction. Breast cancer survivors that underwent a lumpectomy, reported being more satisfied with cosmetic outcomes but almost all reported radiation side-effects with skin thickening listed as the most common. Lumpectomy was also associated with higher chronic pain frequency compared to mastectomy. The overall surgical treatment satisfaction reported by mastectomy and lumpectomy respondents was similar. The composite findings will provide information that will aid future breast cancer patients in making a decision between having a mastectomy or a lumpectomy.

Abstract
Background We have been practicing hypofractionation, 40 Gy in 16 fractions over 3 weeks for whole breast irradiation (WBI) for the past five decades with or without boost at our center. In this study, we compared two boost schedules of 10 Gy/5#/1 week with 16 Gy/8#/1.5 weeks in postlumpectomy patients with breast cancer after WBI. Materials and Methods From June 2012 to June 2016, the study included 87 breast cancer patients postbreast conservation surgery. The institutional ethics committee approved the study, which was registered with ClinicalTrials.gov (ClinicalTrials.gov identifier no. CT02142907). All patients were treated with WBI of 40 Gy/16#/3 weeks. WBI was followed by tumor bed boost of 10 Gy/5#/1 week in 44 patients and 16 Gy/8#/1.5 weeks in 43 patients, either with electron beam therapy or 3D CRT with photons. The primary endpoint of the study was the comparison of local control between two schedules. Secondary endpoints were acute and late radiation toxicities, cosmetic score analysis, disease-free survival (DFS), and overall survival (OS). The assessment of acute and late skin toxicity was made as per RTOG scores and LENT-SOMA scale. The cosmetic assessment was made with Harvard/NSABP/RTOG Breast Cosmesis Grading Scale. Results Median follow-up was 55 months (range 18-78 months). Local recurrence was seen in 1 (2.3%) patient in the 16 Gy boost only. Acute Grade 2 skin toxicity was 33% in 16 Gy boost arm compared to 23% in 10 Gy boost arm. Late skin toxicities were also high in patients with 16 Gy boost. Grade ≥2 induration was seen in 4.5% and 14% of patients with 10 Gy and 16 Gy boost, respectively. None of the patients with 10 Gy boost had Grade 2 edema as compared to 5% with 16 Gy. Pigmentation was observed in 9% and 23% patients with 10 Gy and 16 Gy boost, respectively. Grade 1 fibrosis was 2% versus 12% in patients with 10 Gy and 16 Gy boost, respectively. The cosmetic score was good/excellent in 91% and 84% of patients with 10 Gy and 16 Gy boost, respectively. Distant metastasis occurred in 2 (4%) and 3 (7%) patients in 10 Gy and 16 Gy boost, respectively. DFS and OS at 5 years were comparable between the two boost schedules. Conclusion Local control was comparable with 10 Gy and 16 Gy boost. Acute and late skin toxicities were higher with 16 Gy boost dose. The cosmetic score was better with 10 Gy boost. DFS and OS was comparable with the two boost schedules. Hence, a boost of 10 Gy/5# after WBI may be adequate in patients with breast cancer.

Abstract
PURPOSE Almost one in four lumpectomies fails to fully remove cancerous tissue from the breast, requiring reoperation. This high failure rate suggests that existing lumpectomy guidance methods are inadequate for allowing surgeons to consistently identify the proper volume of tissue for excision. Current guidance techniques either provide little information about the tumor position or require surgeons to frequently switch between making incisions and manually probing for a marker placed at the lesion site. This article explores the feasibility of thermo-acoustic ultrasound (TAUS) to enable hands-free localization of metallic biopsy markers throughout surgery, which would allow for continuous visualization of the lesion site in the breast without the interruption of surgery. In a TAUS-based localization system, microwave excitations would be transmitted into the breast, and the amplification in microwave absorption around the metallic markers would generate acoustic signals from the marker sites through the thermo-acoustic effect. Detection and ranging of these signals by multiple acoustic receivers on the breast could then enable marker localization through acoustic multilateration. METHODS Physics simulations were used to characterize the TAUS signals generated from different markers by microwave excitations. First, electromagnetic simulations determined the spatial pattern of the amplification in microwave absorption around the markers. Then, acoustic simulations characterized the acoustic fields generated from these markers at various acoustic frequencies. TAUS-based one-dimensional (1D) ranging of two metallic markers-including a biopsy marker that is FDA-approved for clinical use-immersed in saline was also performed using a bench-top setup. To perform TAUS acquisitions, a microwave applicator was driven by 2.66 GHz microwave signals that were amplitude-modulated by chirps at the desired acoustic excitation frequencies, and the resulting TAUS signal from the markers was detected by an ultrasonic transducer. RESULTS The simulation results show that the geometry of the marker strongly impacts the quantity and spatial pattern of both the microwave absorption around the marker and the resulting TAUS signal generated from the marker. The simulated TAUS signal maps and acoustic frequency responses also make clear that the marker geometry plays an important role in determining the overall system response. Using the bench-top setup, TAUS detection and 1D localization of the markers were successfully demonstrated for multiple different combinations of microwave applicator and metallic marker. These initial results indicate that TAUS-based localization of biopsy markers is feasible. CONCLUSIONS Through microwave excitations and acoustic detection, TAUS can be used to localize metallic biopsy markers. With further development, TAUS opens new avenues to enable a more intuitive lumpectomy guidance system that could help to achieve better lumpectomy outcomes.

Abstract
BACKGROUND Assessment of margins after breast conservation surgery is an essential part of management in breast cancer and is important in prognostication of the patient. Various intra-operative techniques like frozen section and imprint cytology are in use to ensure negative margins but have their limitations in the fact that 3D evaluation is not feasible. These lead to false negatives and also are operator dependent. In order to obviate these shortcomings, various centers are using specimen imaging (specimen mammogram and ultrasonography). AIMS AND OBJECTIVES 1) To evaluate the accuracy of specimen ultrasonography in assessing the margins following breast conservation surgery (BCS). 2) To compare the accuracy of intra-operative specimen ultra-sonography with frozen section for assessment of excision margins following BCS. MATERIALS AND METHODS Sixty-two biopsy-proven patients with breast cancer who underwent BCS were included in this prospective study at a tertiary cancer care center. The oriented specimens were evaluated by specimen ultrasonography and later by frozen section. The final histopathology served as the gold standard. RESULTS Specimen ultrasonography is found to be superior to frozen section in providing detailed assessment of margins in patients undergoing breast conservation. Specimen ultrasonography was also able to detect additional lesions which might be missed on frozen section, especially the in-situ carcinoma.

Abstract
Introduction: New medical devices must have adequate research, such that outcomes are known, enabling patients to be consented with knowledge of the safety and efficacy of the device to be implanted. Device trials are challenging due to the learning curve and iterative assessment of best practice. This study is designed to pilot a national collaborative approach to medical device introduction by breast surgeons in the UK, using breast localisation devices as an exemplar. The aim is to develop an effective and transferable surgical device platform protocol design, with embedded shared learning. Methods and analysis: The iBRA-net localisation study is a UK based prospective, multi-centre platform study, comparing the safety and efficacy of novel localisation devices with wire-guided breast lesion localisation for wide local excision, using Magseed® as the pilot intervention group. Centres performing breast lesion localisation for wide local excision or excision biopsy will be eligible to participate if using one of the included devices. Further intervention arms will be added as new devices are CE marked. Outcomes will be collected via an online database. The primary outcome measure will be identification of the index lesion. Participating surgeons will be asked to record shared learning events via online questionnaires and focus group interviews to inform future study arms. Ethics and dissemination: The study will aim to collect data on 950 procedures for each intervention (Magseed® and wire localisation) from UK breast centres over an 18-month period. Shared learning will be prospectively evaluated via thematic analysis to refine breast localisation technique and to promote early identification of potential pitfalls and problems. Results will be presented at national and international conferences and published in peer reviewed journals. Registration: This is a UK national audit registered with Manchester University NHS Foundation Trust. Highlights

Abstract
The pectoral nerves 2 (pecs 2) block is widely used as adjunct to general anaesthesia for breast surgery. There are a few case reports and a single case series that describe regional anaesthesia as a single technique or supplemented by light to moderate sedation. Here we describe the management of a 91-year-old ASA physical status 4 patient who presented with a T4 breast malignancy. She was considered unfit for general anaesthesia due to significant valvular heart disease. A wide local excision was successfully performed under a pecs 2 block and a transverse thoracis plane block, supplemented with light sedation. We consider this technique to be a good option for selected patients who are considered unfit for general anaesthesia.

Abstract
Immediate oncoplastic breast reconstruction performed at the time of breast conserving surgery for the treatment of breast cancer merges the therapeutic goals of complete oncologic extirpation with preservation of breast form and function. A constellation of surgical techniques that employs breast volume displacement and/or replacement methods of varying complexity levels have emerged, thus broadening the potential applications for breast conservation therapy to include cases with increased tumor-to-native breast-volume ratios, multicentric or multifocal disease, and/or previous margin-positive resections. This review describes the various reconstructive methods, including the use of local tissue rearrangement, oncoplastic reduction-mastopexy, and locoregional flaps. Classification of the surgical options into levels I and II volume-displacement and volume-replacing techniques is made. Additionally, we explore the oncologic safety and effectiveness of this treatment paradigm by summarizing existing supportive evidence regarding associated risk of surgical complications, rate of margin-positive resection, implications for radiographic surveillance, local recurrence rates, and patient-reported outcomes. In conclusion, surgeons may use a wide variety of oncoplastic techniques for partial breast reconstruction at the time of segmental mastectomy to deliver effective breast conserving treatment for women with breast cancer. A growing body of literature affirms the oncologic safety of this approach. Future directions for research include long-term follow-up data with emphasis on outcomes from patient perspectives.

Abstract
BACKGROUND Neoadjuvant chemotherapy (NAC) increases breast-conserving surgery (BCS) rates with comparable locoregional control and survival outcomes to adjuvant therapy. More women are receiving NAC and achieving pathologic complete responses (pCR). This study sought to evaluate the effect of NAC on surgical outcomes after the adoption of a "no-ink-on-tumor" margin policy in patients undergoing primary BCS (PBSC). METHODS An IRB approved database was queried for women undergoing BCS for invasive breast cancer after March 2014. We compared patients who underwent NAC followed by BCS versus PBCS. Demographic, tumor, treatment, and outcome variables were compared using both univariate and multivariable analysis. RESULTS A total of 162 patients were evaluated. NAC patients had significantly lower re-excision rates (0% NAC vs. 9% PBCS, p = .03), margin positivity (0% NAC vs. 5% PBCS, p = .01), and greater patient satisfaction with breast cosmesis (97 NAC vs. 77 PBCS, p = .01). On multivariable analysis, NAC was not an independent predictor of lower final resection volume, total complications, or greater satisfaction with breasts when controlling for age and T category at diagnosis. CONCLUSION NAC followed by BCS may offer less margin positivity, lower re-excision rates, and greater patient satisfaction when compared to a contemporary PBCS cohort in the "no-ink-on-tumor" era.

Abstract
OBJECTIVE Three-dimensional bioabsorbable tissue marker (BTM) placement during breast surgery is performed for the purpose of improved surgical cavity delineation for radiotherapy and improved cosmetic outcome. The purpose of this study is to evaluate the postsurgical imaging findings of BTM. METHODS This Institutional Review Board-approved retrospective review included all patients implanted with BTM at breast surgery from January 2017 to September 2018. Demographics, tumor characteristics, imaging, and histologic findings were evaluated. Medical records were reviewed during a three-year period to evaluate for tumor recurrence. RESULTS Ninety-seven patients had BTM implanted, of which 76 patients had imaging follow-up of at least 1 year. Of the 76 patients who had mammographic follow-up, 3 (3.9%) developed suspicious microcalcifications requiring biopsy, yielding ductal carcinoma in-situ in 2 patients and benign calcifications in 1 patient. Of 61 patients who had sonographic follow-up, 44 (72.1%) patients had complex fluid collections containing avascular, heterogeneously hyperechoic solid components, which remained stable or decreased in size over time; no recurrent tumors were found in this group. One patient (1.6%) had a vascular solid mass, which yielded recurrent papilloma. Four (6.6%) patients developed irregular hypoechoic masses at the surgical site, one of which corresponded with a developing asymmetry mammographically; biopsy yielded fibromatosis. Tissue sampling of the remaining three cases yielded invasive ductal carcinoma, fat necrosis, and radiation changes, respectively. CONCLUSION Accurate identification of the expected postoperative imaging appearance of BTM may prevent unnecessary biopsy. Suspicious findings necessitating biopsy are pleomorphic calcifications, developing asymmetry and vascular and irregular hypoechoic masses.

Abstract
BACKGROUND Decision making regarding the initial treatment of women with breast cancer is complicated. In the current study, the authors examined the relationship between treatment choices and their children's ages among young women with early-stage breast cancer. METHODS Using the MarketScan Commercial Claims and Encounters database, the authors identified women aged 20 to 50 years who underwent lumpectomy or mastectomy for early-stage breast cancer between 2008 and 2014. Predictors of compliance with radiotherapy after undergoing lumpectomy and of undergoing mastectomy were determined using multinomial logistic regression. The authors conducted sensitivity analyses to explore the impact of the number of young-aged children and a reduction in the sample size in 2014 due to the attrition of health plans contributing to MarketScan. RESULTS A total of 21,052 women were included in the current analysis. Among women with at least 1 child aged <7 years, the adjusted rate of lumpectomy was 59.9%; approximately 22% of these women did not receive radiotherapy. Compared with women undergoing lumpectomy plus radiotherapy, women with at least 1 child aged <7 years or aged 7 to 12 years were 25% and 16%, respectively, more likely to undergo lumpectomy alone compared with women with no children aged <18 years (P = .002 and P = .012, respectively) and 64% and 37%, respectively, more likely to undergo mastectomy (P < .001). CONCLUSIONS Among privately insured women with breast cancer, having young children was found to be strongly associated with the omission of postlumpectomy radiotherapy or undergoing mastectomy. Having >1 young-aged child further amplified these associations. The findings of the current study suggested that caring for young children may present unique challenges to young women with breast cancer.

Abstract
When there is extensive breast cancer, patients typically undergo mastectomy. However, lumpectomy may still be performed for patients who are motivated to avoid a mastectomy and understand the risk for positive margins requiring second surgery in unique cases. This report details the surgical management and clinical reasoning behind lumpectomy for a multicentric breast cancer spanning 5 cm. The lumpectomy was a success with negative margins on final pathology.

Abstract
Breast lumpectomy is usually performed under general or local anesthesia. To the best of our knowledge, whether conscious sedation with intranasal dexmedetomidine and local anesthesia is an effective anesthetic technique has not been studied. Thus, the present study aimed to investigate the effectiveness of conscious sedation with intranasal dexmedetomidine combined with local anesthesia in breast lumpectomy, and to identify its optimal dose. A prospective randomized, double-blinded, placebo-controlled, single-center study was designed, and patients undergoing breast lumpectomies were recruited based on the inclusion and exclusion criteria. All patients were randomly allocated to four groups: i) Local anesthesia with 0.9% intranasal saline (placebo); local anesthesia with ii) 1 µg.kg−1; iii) 1.5 µg.kg−1; or iv) 2 µg.kg−1 intranasal dexmedetomidine. The sedation status, pain relief, vital signs, adverse events, and satisfaction of patient and surgeon were recorded. Patients in the three dexmedetomidine groups were significantly more sedated and experienced less pain compared with the placebo group 45 min after intranasal dexmedetomidine administration and during 30 min in the post-anesthesia care unit. Patients in the 1.5 µg.kg−1 group were more sedated compared with the 1 µg.kg−1 group (without reaching statistical significance), whereas the 1.5 µg.kg−1 group exhibited a similar level of sedation 45 min after intranasal dexmedetomidine administration compared with the 2 µg.kg−1 group. In addition, patients in the 1 and 1.5 µg.kg−1 group experienced no adverse hemodynamic effects. Patient and surgeon satisfaction were greater in the 1.5 µg.kg−1 group compared with the 1 and 2 µg.kg−1 groups. Taken together, the results of the present study suggested that conscious sedation with intranasal dexmedetomidine and local anesthesia may be an effective anesthetic for breast lumpectomy surgery, and that the optimal dose for intranasal dexmedetomidine administration may be 1.5 µg.kg−1, as it resulted in good sedation and patient satisfaction without adverse effects.

Abstract
Background Lumpectomy followed by radiation, known as breast conservation therapy (BCT), is a viable surgical treatment option for early-stage breast cancer. However, the current literature suggests that patients prefer mastectomy over BCT, likely due to the wide variety of postmastectomy reconstructive options. Our aim is to investigate the objective health burden of living with BCT to help surgeons gain a better understanding of patient treatment preferences. Methods Three validated health state utility tools were used to objectify the burden of living with post-BCT results: visual analogue scale (VAS), time trade-off (TTO), and standard gamble (SG). A prospective sample of the general population and medical students were recruited, and their responses analyzed to attain these scores. Results Utility scores for living with BCT are VAS 0.81 ± 0.19, TTO 0.93 ± 0.10, and SG 0.92 ± 0.14. The TTO and SG suggest a willingness to trade 2.5 years of life years and an 8% chance of death undergoing reconstructive procedures to correct a BCT defect, respectively. Age, gender, race, education, and income were not statistically significant independent predictors for higher or lower utility scores. Conclusion The impact of the health burden of BCT was ascertained using validated objective numeric utility scores. These indices demonstrate a willingness to trade less life years to undergo correction of a BCT defect than reconstruction following unilateral mastectomy. They can provide surgeons with the best objective understanding of patient preferences for shared decision-making in the management of breast cancer.

Abstract
Concomitant comorbidity is a key factor in treatment decision-making for breast cancer. The aim of this study was to determine how the Charlson Comorbidity Index (CCI) affected treatment and risk of mortality of women with TNBC, the subtype with the poorest prognosis. We accessed 20 177 cases of TNBC from the California Cancer Registry 2000-2015 with documented Charlson Comorbidity Index (CCI). Cox Regression was used to compute the adjusted risk of breast cancer-specific mortality for a CCI of 1 (low comorbidity) and 2+ (high comorbidity) vs a CCI of 0 (no comorbidity). Logistic regression was used to compute the association of CCI with treatment of mastectomy, lumpectomy + radiation, and chemotherapy. Analyses were conducted separately for each stage. Patients with high comorbidity CCI (2+) were less likely to receive systemic chemotherapy irrespective of Stage. High comorbidity was associated with higher breast-specific mortality in all stages of disease. High comorbidity did not have an effect on the use of lumpectomy and radiation of stage 1 breast cancer but was associated with reduced use in stages 2-4. Comorbidity was not associated with decreased risk of mastectomy except for patients with high comorbidity in stage 3. Concomitant comorbidity influences treatment decisions and breast cancer-specific mortality in patients with TNBC.

Abstract
Purpose An imbalance in perioperative cytokine response may cause acute pain and postoperative complications. Anesthetic drugs modulate this cytokine response, but their role in non-major breast cancer surgery is unclear. In an exploratory study, we investigated whether intravenous lidocaine and dexamethasone could modulate the cytokine response into an anti-inflammatory direction. We also evaluated interrelationships between cytokine levels, pain scores and postoperative complications. Our goal is to develop multimodal analgesia regimens optimizing outcome after breast cancer surgery. Patients and Methods Forty-eight patients undergoing a lumpectomy were randomly assigned to placebo or lidocaine (1.5 mg⋅kg−1 followed by 2 mg⋅kg−1⋅hour−1) supplemented by dexamethasone zero, 4 or 8 mg, yielding six groups of eight patients. Interleukin (IL)-1β, IL-1Ra, IL-6, IL-10 levels and pain scores were measured at baseline and four hours postoperatively. We assessed postoperative complications occurring within 30 days. We noted persistent pain and infections as potential immune-related complications (PIRC). We used multiple regression to disentangle the effects of the individual study drugs (given by their partial regression coefficients (b)). Odds ratios (OR) estimated the link between pain scores and complications. Results Dexamethasone 8 mg increased IL-10 (b=12.70 (95% CI=8.06–17.34), P<0.001). Dexamethasone 4 mg and 8 mg decreased the ratio IL-6/IL-10 (b=−2.60 (−3.93 to −1.26), P<0.001 and b=−3.59 (−5.04 to −2.13), P<0.001, respectively). We could not show modulatory effects of lidocaine on cytokines. High pain scores were linked to the occurrence of PIRC’s (OR=2.028 (1.134–3.628), P=0.017). Cytokine levels were not related either to acute pain or PIRC. Conclusion Dexamethasone modulated the perioperative cytokine response into an anti-inflammatory direction. An overall lidocaine effect was not found. Patients with higher pain scores suffered from more 30-day PIRCs. Cytokine levels were not associated with pain or more postoperative complications, even not with PIRC. Larger studies in breast cancer surgery are needed to confirm these explorative results.

Abstract
OBJECTIVES In partial mastectomy (PM) or lumpectomy, ultrasound (US) localization avoids discomfort and additional procedures associated with wire localization. The purpose of this study was to evaluate the association between ultrasound-visible clip (UVC) use at the time of biopsy and US use during resection, hypothesizing that UVCs facilitate US localization and reduce costs compared with traditional radiopaque clips or no clip placement. METHODS The study population consisted of adult female patients with breast cancer undergoing PM or lumpectomy at our institution between 2014 and 2016. The core biopsy clip type and localization method during PM were characterized as wire localization versus US localization, and associations were estimated with multivariable regression models. For the cost evaluation, breast biopsy data were obtained from the Department of Radiology. RESULTS Among 674 patients, 490 had data on localization and the clip type. Ultrasound-visible clip placement at biopsy increased US use during resection by 13% (95% confidence interval, 6%-21%). There was no difference in the total specimen weight with US versus wire localization. The cost savings for using UVCs for the 2209 patients who underwent breast biopsy from 2014 to 2016 was $36,000. CONCLUSIONS This study demonstrates that US localization for PM is feasible at a single institution and cost-effective when facilitated by UVCs. Placement of a UVC at the time of biopsy is recommended, as it is cost-effective and avoids the discomfort and inconvenience of wire localization.

Abstract
Breast cancer is the most common cancer in American women, and is the second most deadly. Current guidance approaches for breast cancer surgery provide distance to a seed implanted near the tumor centroid. Large deformations between preoperative imaging and surgical presentation, coupled with the lack of tumor extent information leads to difficulty in ensuring complete tumor resection. Here we propose a novel image guidance platform that utilizes character-based fiducials for easy detection and small fiducial points for precise and accurate localization. Our system is work-flow friendly, and near-real time with use of stereo cameras for surface acquisition. Using simple image processing techniques, the proposed technique can localize fiducials and character labels, providing updates without relying on video history. Character based fiducial labels can be recognized and used to determine correspondence between left and right images in a pair of stereo cameras, and frame to frame in a sequence of images during a procedure. Letters can be recognized with 89% accuracy using the MATLAB built in optical character recognition function, and an average of 81% of points can be accurately labeled and localized. The stereo camera system can determine surface points with accuracy below 2mm when compared to optically tracked stylus points. These surface points are incorporated to a four-panel guidance display that includes preoperative supine MR, tracked ultrasound, and a model view of the breast and tumor with respect to optically tracked instrumentation.

Abstract
BACKGROUND AND OBJECTIVES Re-excision surgery is undertaken to obtain clear margins after breast-conserving surgery (BCS) for localized breast cancer. This study examines patient and tumor characteristics related to re-excision surgery in the universal-access Military Health System (MHS). METHODS Retrospective analysis of patients with pathologically confirmed stage I-III breast cancer between 1998 and 2014 in the Department of Defense Central Cancer Registry and MHS Data Repository-linked databases who received primary BCS. Multivariable stepwise logistic regression methods identified characteristics associated with re-excision surgery (lumpectomy and mastectomy) and conversion to mastectomy, given as adjusted odds ratios (AOR) and 95% confidence intervals (CIs). RESULTS Of 7637 women receiving BCS, 26.3% had a re-excision and 9.9% converted to mastectomy. Tumor location, larger tumor size (≥4 cm), and regional lymph node involvement were associated with a greater likelihood of re-excision and mastectomy conversion. Pathology before BCS (AOR, 0.39; 95% CI, 0.35, 0.44 for re-excision) and neoadjuvant treatment (AOR, 0.50; 95% CI, 0.36, 0.69 for re-excision) were associated with a decreased likelihood of these outcomes. Additionally, age, tumor histology, and military-specific variables were associated with mastectomy conversion. CONCLUSION Comprehensive preoperative workup, including tumor pathology, may better inform surgical decision-making and reduce re-excision rates.

Abstract
RATIONALE Liver transplantation (LT) is the preferred surgical option for the treatment of early hepatocellular carcinoma (HCC). In contrast, surgical treatment of progressive HCC metastasized to the spine following LT constitutes a considerable challenge. Here, we report the first case of progressive HCC metastasized to the T12 vertebra after local radiotherapy, treated successfully with en bloc lumpectomy following LT for HCC. PATIENT CONCERNS A 40-year-old man who had undergone LT for the treatment of HCC 2 months prior presented to our clinic with symptoms of progressive back pain. Magnetic resonance imagining (MRI) and positron emission tomography (PET) examinations showed a solitary metastasis at T12 without recurrence in the liver or metastasis to other organs. DIAGNOSES The patient was diagnosed with HCC metastasized to the T12 vertebra after liver transplantation. INTERVENTIONS Local radiation therapy of the T12 vertebra was performed; however, the lesion continued to grow one month after irradiation. Accordingly, the patient was treated with en bloc lumpectomy of the T12 vertebra. After surgery, the patient reported significant pain relief. At 11 months post-surgery, a C4 metastasis with spinal cord compression was revealed by MRI. Multiple grafted liver metastases were also detected by ultrasound along with several lung metastases, which were discovered by X-ray. The patient was treated with a pedicle screw system and a mesh cage filled with frozen autografts for C4 metastasis. OUTCOMES The patient died 15 months after liver transplantation due to recurrence in the liver and metastasis to the lung. LESSONS En bloc lumpectomy may be a viable therapeutic option for patients with progressive solitary spinal metastases after LT refractory to radiotherapy. Use of immunosuppressive therapy after LT may significantly inhibit immune function, making patients more susceptible to HCC recurrence and bone metastasis.

Abstract
Adjuvant radiation therapy is often delivered after breast cancer surgery, both in the post-lumpectomy and post-mastectomy settings. Standard fractionation whole breast irradiation (SF-WBI), which is typically delivered over 5-7 weeks, was previously considered the standard of care. More recent data has helped to establish hypofractionated whole breast irradiation (HF-WBI), which consists of a 3-4 week regimen, as a new standard of care. This article provides an overview of the major randomized trials that support the routine use of HF-WBI for the majority of patients undergoing breast-conserving surgery for early-stage breast cancer. Newer data on the use of a hypofractionated approach in the post-mastectomy setting, as well as ongoing randomized trials addressing this topic, are also discussed.

Abstract
Aim In the present study, surface doses within the target area and contralateral breast (CLB) received during conventional treatment of carcinoma breast are evaluate and compared for treatment on two different beam energies, i.e., Co-60 γ-ray and 6 MV X-ray beams with thermoluminescent dosimeter, LiF:Mg, Ti (TLD-100). Materials and Methods The study includes a group of 23 patients comprising 11 patients treated with Co-60 γ-ray beam and 12 patients by 6 MV X-ray beam. Results and Discussion The treatment using Co-60 γ-ray and 6 MV X-ray beams contributes an average percentage dose of 8.15% ± 0.56% and 4.73% ± 0.94%, respectively, to CLB in mastectomy patients. The contribution of tangential fields (mastectomy) to the CLB doses ranges between 12.71 and 16.40 cGy (5.45%-7.03%) for treatment with Co-60 γ-ray beam and 6.33-10.95 cGy (1.86-4.69%) for treatment with 6 MV X-ray beam. The supraclavicular field (SCF) contributes 1.45%-1.93% and 1.02%-1.43% for treatment with Co-60 γ-ray and 6 MV X-ray beams, respectively. The average surface dose (normalized with breast dose) 89.1% ± 8.5% for Co-60 beam in the SCF region differs significantly from the 60.2% ± 13.0% value for 6 MV X-ray beam. Conclusion The CLB doses for mastectomy patients are higher for Co-60 beam as compared to 6 MV X-ray beam, and better dose homogeneity is achieved within the irradiated breast from 6 MV X-ray beam. The CLB doses are slightly higher for patients treated with breast conservative radiotherapy or lumpectomy. The average surface dose to SCF decreases by ~30% of treated breast dose for treatment with 6 MV X-ray beam.

Abstract
BACKGROUND In addition to conventional breast-conserving surgery (BCS), oncoplastic breast surgery (OBS) is an operation technique that strives simultaneously to increase oncological safety and patient's satisfaction. It is the combination of the best-proven techniques in plastic surgery with surgery for breast cancer. In a growing number of indications, OBS overcomes the limit of conventional BCS by allowing larger resection volumes while avoiding deformities. The aim of our retrospective study (2012-2014) was to compare oncological outcomes of OBS versus BCS. METHODS We compared two groups of patients with primary non-metastatic breast tumours: group A (n = 291), where BCS was performed, versus group B (n = 52), where OBS was performed. Surgical interventions were performed in German and Swiss teaching hospital settings. The surgeon for group B had subspecialist training in OBS. We assessed outcome in term of re-excision rates, resection margin and complications. RESULTS Groups were homogenous (no significant differences in terms of age, tumour size, tumour type or grade). The resection margin was larger in group B (7 mm) than in group A (3 mm). Re-excision rate of group B (8%) was significantly lower than in group A (31%). Complication rates were comparably low in groups A and B. CONCLUSION Despite the limits of retrospective design, our study confirms that OBS is safe and reduces the re-excision rates and the need for further surgery. OBS has the potential to improve oncological care and should be more widely adopted.

Abstract
Purpose To report characteristics of our treatment scheme of high-dose-rate (HDR) brachytherapy of breast cancer and to show the first outcomes of dosimetric planning analysis based on dose-volume histogram (DVH). Material and methods Since August 2017, 25 patients diagnosed with T1N0M0 breast cancer have received a treatment in our center. There was lumpectomy and following breast HDR brachytherapy (10 fractions of 3.4 Gy) administered to each patient. A planning target volume (PTV) and organs at risk (OARs) were recorded with DVH analysis. Results The study describes the full procedure of breast HDR brachytherapy with the lumpectomy. Twenty-five patients were treated, including 9 with cancer of the left breast and 16 of the right breast. The median age was 65 years. The first analysis of DVH data shows that the main OARs were ribs and skin. Mean value of Dmax (ribs) for all patients was 19.90 Gy (55.88% of prescribed dose) and for the skin 30.88 Gy (90.74% of prescribed dose). During the treatment, there was only one case of toxic effects, which was pigmentation on the skin due to excess of dose limit of 1.4 Gy. Therefore, the limit exceeding of 1 Gy does not give any significant toxic effects. Conclusions This study is the first stage of the dosimetric evaluation of a new method. The analysis allows treating complex localizations of the breast cancer, for example, in a close position to the skin or ribs. In order to minimize the toxic effects, it is necessary to consider patient selection, catheter administration, and dose optimization.

Abstract
Background We have previously shown that breast cancer surgery affects breast specific sensuality, and that women who undergo mastectomy may have worse sexual function outcomes than those who undergo lumpectomy. It is less clear if patients who undergo prophylactic mastectomy are equally as affected as those with a cancer diagnosis. We sought to compare sexual function outcomes and their relationship to depression and anxiety between BRCA mutation carriers (mBRCA) with and without cancer in order to guide surgical counseling and improve survivorship outcomes. Methods A confidential, cross-sectional survey was distributed electronically to mBRCA at least 18 years of age. The survey included investigator-generated questions, the Female Sexual Function Index (FSFI), and the Hospital Anxiety and Depression Scale (HADS) surveys. Responses were analyzed in total and divided into two subgroups: those with and without breast cancer. Results Sixty-three mBRCA responded (37%) of 170 email addresses were identified, and 77% were postmenopausal. Although more than half of all mBRCA reported that the role of the breast in intimacy was important, most patients without cancer and all of those with cancer experienced an impressive decline in certain breast-specific sensuality parameters postoperatively. Among those without cancer, anxiety scores were not different between those choosing prophylactic mastectomy and high-risk screening (HRS). Sexual function as measured by the FSFI was negatively correlated with depression and anxiety in mBRCA. FSFI scores were not significantly different between those with and without cancer. However, the median FSFI of mBRCA with cancer, those undergoing HRS, and those who underwent prophylactic mastectomy indicated sexual dysfunction. Conclusions As the availability of genetic testing increases, more women are found to harbor BRCA mutations and must choose between HRS and prophylactic surgery. Women with BRCA mutations, both with and without breast cancer, are susceptible to derangements in sexual function during the course of both screening or treatment, and this appears to be negatively correlated to depression and anxiety.

Abstract
We queried the National Cancer Database for nonmetastatic breast angiosarcoma, yielding 808 patients (202 de novo, 606 secondary). The median survival was 53.7 months. Secondary tumors were more likely to undergo mastectomy than de novo lesions (OR = 3.99, P < 0.001). Treatments included lumpectomy (10%), lumpectomy/radiation (3%), mastectomy alone (73%), or mastectomy/radiation (14%), with no difference in survival (P = 0.68). Lumpectomy correlated with positive margin rate (OR 3.29), which was a predictor for death (HR = 2.37, P < 0.01), along with older age, higher comorbidity scores, size >5 cm, and high-grade disease (P < 0.05). While breast angiosarcoma is usually treated with mastectomy, lumpectomy may be feasible for well-selected tumors.

Abstract
Background The rate of mastectomy is much higher in Newfoundland and Labrador than in any other province in Canada, even for women diagnosed at an early stage. In this paper, we present qualitative data from women who have made a decision for surgical treatment and from breast surgeons in an effort to better explicate factors influencing breast cancer (bca) surgical decision-making. Methods The study's descriptive, qualitative design involved holding interviews with breast surgeons and holding focus groups and interviews with women who were offered the choice of breast-conserving surgery (bcs) or mastectomy (mt). Results Participants included 35 women and 13 surgeons. High interest in mt and increasing requests for prophylactic contralateral mt were evident. A host of factors-clinical, demographic, psychosocial, education-related, and cultural-influenced the decisions. A key factor for women was fear of recurrence and a need to "just get rid of it," but the experiences of others also influenced the decisions. Life stage and family considerations also factored prominently into women's decisions. Conclusions Women with early-stage bca more often chose mt and often demanded prophylactic removal of the healthy breast. Findings highlight the importance of ensuring that women at average risk are appropriately counselled about the low likelihood of a subsequent contralateral bca and the lack of survival benefit associated with prophylactic contralateral mt. Findings also revealed other areas of presurgical discussion that might help women think through their personal circumstances and values so as to encourage informed surgical decisions.

Abstract
Intraoperative assessment of breast surgical margins will be of value for reducing the rate of re-excision surgeries for lumpectomy patients. While frozen-section histology is used for intraoperative guidance of certain cancers, it provides limited sampling of the margin surface (typically <1 % of the margin) and is inferior to gold-standard histology, especially for fatty tissues that do not freeze well, such as breast specimens. Microscopy with ultraviolet surface excitation (MUSE) is a nondestructive superficial optical-sectioning technique that has the potential to enable rapid, high-resolution examination of excised margin surfaces. Here, a MUSE system is developed with fully automated sample translation to image fresh tissue surfaces over large areas and at multiple levels of defocus, at a rate of ∼5 min / cm2. Surface extraction is used to improve the comprehensiveness of surface imaging, and 3-D deconvolution is used to improve resolution and contrast. In addition, an improved fluorescent analog of conventional H&E staining is developed to label fresh tissues within ∼5 min for MUSE imaging. We compare the image quality of our MUSE system with both frozen-section and conventional H&E histology, demonstrating the feasibility to provide microscopic visualization of breast margin surfaces at speeds that are relevant for intraoperative use.

Abstract
OBJECTIVE The purpose of this study was to evaluate the magnetic occult lesion localization instrument (MOLLI) system that involves implantation of a small, ferromagnetic marker to guide surgical excision of nonpalpable breast lesions. Characterization of the system was undertaken as part of what is, to our knowledge, the first study to assess the MOLLI system. MATERIALS AND METHODS The MOLLI system consists of a handheld probe that can detect the position and distance of an implanted magnetic marker. The system presents the surgeon with an accurate assessment of lesion location and depth measurement for precise 3D localization. The marker is implanted under ultrasound or mammographic guidance at any time before the surgical procedure and requires no special precautions. Experimental analysis focused on characterization of the following aspects of the MOLLI system: visualization of the marker under imaging, 3D detection of the magnetic marker, spatial resolution of the probe to detect markers placed in close proximity, and the effect of signal interference on system performance. RESULTS The MOLLI system can reliably detect mean (± SD) marker depths up to 53 ± 8.56 mm from the probe. Bracketing large lesions or localizing multiple lesions can be accomplished by placing markers as close as 10 mm apart, at depths of up to 42 mm. The biologically inert MOLLI marker is readily visible under ultrasound and mammographic guidance, and it is differentiable from radiologic clips. The effect of surgical instruments on MOLLI functioning is minimal and does not impact system accuracy or reliability. CONCLUSION The MOLLI system offers an accurate and efficient alternative lesion localization method for nonpalpable breast lesions.

Abstract
Terahertz imaging and spectroscopy has demonstrated a potential for differentiating tissue types of excised breast cancer tumors. Pulsed terahertz technology provides a broadband frequency range from 0.1 THz to 4 THz for detecting cancerous tissue. Tumor tissue types of interest include cancer typically manifested as infiltrating ductal or lobular carcinomas, fibro-glandular (healthy connective tissues) and fat. In this work, images of breast tumors excised from human and animal models are reviewed. In addition to alternate fresh tissues, breast cancer tissue phantoms are developed to further evaluate terahertz imaging and the potential use of contrast agents. Terahertz results are successfully validated with pathology images, showing strong differentiation between cancerous and healthy tissues for all freshly excised tissues and types. The advantages, challenges and limitations of THz imaging of breast cancer are discussed.

Abstract
Background: Breast lumpectomy is an integral part of the treatment of mammary masses in women. This study was conducted to evaluate and compare two-drug combinations of propofol–ketamine (PK) (ketofol) and propofol–fentanyl (PF) (fenofol) on quality of sedation and analgesia in lumpectomy. Materials and Methods: This was a randomized, double-blind, clinical trial performed on 64 patients aged 15–70 years with breast cancer lumpectomy referred to Isfahan's Seyed Al-Shohada Hospital. Consequently, patients were divided into two groups of 32 patients, each group receiving PF combination or PK combination during anesthesia. Results: The patients in two groups, PF and PK, were compared in their sedation levels, severity of pain, and other variables. The mean arterial blood pressure, systolic blood pressure, and heart rate (HR) did not show any significant difference at the beginning of the study in the two groups, but the fenofol (PF) group had a significantly lower oxygen saturation than the ketofol (PK) group. The sedation level was significantly lower in the fenofol group than the ketofol group (P < 0.001). The mean pain intensity was significantly lower in the PF group than the PK group (P < 0.001). Conclusion: The two combinations of ketofol and fenofol cause rapid, favorable, safe anesthetic with minimal side effects and hemodynamic effects but it may be a superior alternative to fenofol combination, in terms of respiratory depression.

Abstract
BACKGROUND Historically, multiple ipsilateral breast cancer (MIBC) has been a contraindication to breast-conserving therapy (BCT). We report the feasibility of BCT in MIBC from the ACOSOG Z11102 trial [Alliance], a single arm noninferiority trial of BCT for women with two or three sites of malignancy in the ipsilateral breast. METHODS Women who enrolled preoperatively in ACOSOG Z11102 were evaluated for conversion to mastectomy and need for reoperation to obtain negative margins. Characteristics of women who successfully underwent BCT and those who converted to mastectomy were compared. Factors were examined for association with the need for margin reexcision. RESULTS Of 198 patients enrolled preoperatively, 190 (96%) had 2 foci of disease. Median size of the largest tumor focus was 1.5 (range 0.1-7.0) cm; 49 patients (24.8%) had positive nodes. There were 14 women who underwent mastectomy due to positive margins, resulting in a conversion to mastectomy rate of 7.1% (95% confidence interval [CI] 3.9-10.6%). Of 184 patients who successfully completed BCT, 134 completed this in a single operation. Multivariable logistic regression analysis did not identify any factors significantly associated with conversion to mastectomy or need for margin reexcision. CONCLUSIONS Breast conservation is feasible in MIBC with 67.6% of patients achieving a margin-negative excision in a single operation and 7.1% of patients requiring conversion to mastectomy due to positive margins. No characteristic was identified that significantly altered the risk of conversion to mastectomy or need for reexcision. CLINICALTRIALS. GOV IDENTIFIER NCT01556243.

Abstract
Breast conserving surgery (BCS) is an effective treatment for early-stage cancers as long as the margins of the resected tissue are free of disease according to consensus guidelines for patient management. However, 15% to 35% of patients undergo a second surgery since malignant cells are found close to or at the margins of the original resection specimen. This review highlights imaging approaches being investigated to reduce the rate of positive margins, and they are reviewed with the assumption that a new system would need high sensitivity near 95% and specificity near 85%. The problem appears to be twofold. The first is for complete, fast surface scanning for cellular, structural, and/or molecular features of cancer, in a lumpectomy volume, which is variable in size, but can be large, irregular, and amorphous. A second is for full, volumetric imaging of the specimen at high spatial resolution, to better guide internal radiologic decision-making about the spiculations and duct tracks, which may inform that surfaces are involved. These two demands are not easily solved by a single tool. Optical methods that scan large surfaces quickly are needed with cellular/molecular sensitivity to solve the first problem, but volumetric imaging with high spatial resolution for soft tissues is largely outside of the optical realm and requires x-ray, micro-CT, or magnetic resonance imaging if they can be achieved efficiently. In summary, it appears that a combination of systems into hybrid platforms may be the optimal solution for these two very different problems. This concept must be cost-effective, image specimens within minutes and be coupled to decision-making tools that help a surgeon without adding to the procedure. The potential for optical systems to be involved in this problem is emerging and clinical trials are underway in several of these technologies to see if they could reduce positive margin rates in BCS.

Abstract
Breast cancer surgery includes a wide array of surgical treatment options. Not only does it involve the oncologic excision of the breast cancer disease but it also involves the reconstruction of the breast. Surgical treatment options vary with regards to the size of the tumor relative to the size of the breast further complicated by the preferences of the patient and the ability of the available surgeon(s). The goal of this paper is to highlight major long-term effects, positive and negative, of modern breast cancer surgery.
