Nipple-sparing mastectomy (NSM) is increasingly popular as a procedure for the treatment of breast cancer and as a prophylactic procedure for those at high risk of developing the disease. However, it remains a controversial option due to questions regarding its oncological safety and concerns regarding locoregional recurrence. This systematic review with a pooled analysis examines the current literature regarding NSM, including locoregional recurrence and complication rates. Systematic electronic searches were conducted using the PubMed database and the Ovid database for studies reporting the indications for NSM and the subsequent outcomes. Studies between January 1970 and January 2015 (inclusive) were analysed if they met the inclusion criteria. Pooled descriptive statistics were performed. Seventy-three studies that met the inclusion criteria were included in the analysis, yielding 12,358 procedures. After a mean follow up of 38 months (range, 7.4-156 months), the overall pooled locoregional recurrence rate was 2.38%, the overall complication rate was 22.3%, and the overall incidence of nipple necrosis, either partial or total, was 5.9%. Significant heterogeneity was found among the published studies and patient selection was affected by tumour characteristics. We concluded that NSM appears to be an oncologically safe option for appropriately selected patients, with low rates of locoregional recurrence. For NSM to be performed, tumours should be peripherally located, smaller than 5 cm in diameter, located more than 2 cm away from the nipple margin, and human epidermal growth factor 2-negative. A separate histopathological examination of the subareolar tissue and exclusion of malignancy at this site is essential for safe oncological practice. Long-term follow-up studies and prospective cohort studies are required in order to determine the best reconstructive methods.

Background The uptake of breast reconstruction is ever increasing with procedures ranging from implant-based reconstructions to complex free tissue transfer. Little emphasis is placed on scarring when counseling patients yet they remain a significant source of morbidity and litigation. The aim of this study was to examine the scarring preferences of men and women in breast oncoplastic and reconstructive surgery. Methods Five hundred men and women were asked to fill out a four-page questionnaire in two large Irish centres. They were asked about their opinions on scarring post breast surgery and were also asked to rank the common scarring patterns in wide local excisions, oncoplastic procedures, breast reconstructions as well as donor sites. Results Fifty-eight percent of those surveyed did not feel scars were important post breast cancer surgery. 61% said that their partners' opinion of scars were important. The most preferred wide local excision scar was the lower lateral quadrant scar whilst the scars from the deep inferior epigastric artery perforator (DIEP) flap were most favoured. The superior gluteal artery perforator flap had the most preferred donor site while surprisingly, the DIEP had the least favourite donor site. Conclusions Scars are often overlooked when planning breast surgery yet the extent and position of the scar needs to be outlined to patients and it should play an important role in selecting a breast reconstruction option. This study highlights the need for further evaluation of patients' opinions regarding scar patterns.

유방암의 수술적 치료에 있어서 종양성형학적 수술이란 종양학적 안정성과 성형적 만족도를 모두 충족시키는 수술을 일컫는 용어이다. 처음 시작한 서양에서는 적은 절개나 절제, 미세침습수술을 지향하기 보다 유방축소술을 기본으로 제거될 조직에 병변을 포함하도록 계획한다. 충분한 절제가 가능하기 때문에 수술 전 검사, 절제연에 대한 고민, 수술 중 병리 검사의 필요성 등도 줄면서 종양학적 안전성에도 도움이 된다고 알려져 왔다. 개개인의 체형에 대한 병변의 종양학적 안정성을 충족시키는 최소 절제 비율에 따라 전위 또는 보충으로 나뉘게 된다. 환자의 기본 체형은 인종적인 영향을 받는 유방암의 특징으로, 유럽, 미국이나 영국의 경우 평균 크기가 대개 36D(600 ㎤) 이상으로, 유방고정술이나 유방축소술이 주로 사용되고, 성형 측면의 최대 목표인 대칭을 위해서는 반대측 유방의 축소도 흔히 이루어지고 있다. 부산대학교병원 유방암 환자 671명의 평균 분포를 분석해 본 결과, 평균은 33A (75%, <35B)로, 대략 체적은 300 ㎤ (75%, <400 ㎤)라고 생각할 수 있다. 따라서 서양과는 다른 수술법이 선택될 수 밖에 없다. 수술 전 MRI를 이용한 범위의 확인을 통한 대상 선정과 함께 초음파와 피부 표식을 이용한 정확한 절제 범위의 계획도 중요하다. 병리적 판독 기준도 절제연 음성이면 종양학적 안정성에 충분하다는 것으로 관점이 바뀐 것은 보존 수술에 유리한 측면이 된다. 동결절편검사는 여전히 고급 전문 인력, 시간이 지나치게 소요되고 있어 편리하고 안전한 병변의 절제에 도움이 될 만한 새로운 방법들이 필요하여 연구되고 있다. 대표적인 최근 연구로는 무선주파수를 이용하는 margin probe, 형광 색소를 결합한 Aqueous Quantum-Dot-Molecular Probes 등을 들 수 있다. 합병증 측면에서 박리 면적이 늘어나는 종양성형학적 수술의 단점을 보강할 수 있는 최근 기술로 초음파 에너지 기구들이 유용하고, 수술 범위가 늘어남에 따라 생길 수 있는 혈종이나 장액 저류의 감소에 도움이 될 수 있다.

Background Breast-conserving therapy is defined as a breast-conserving wide local excision (WLE) of a mammary tumour combined with postoperative radiotherapy. Immediate restoration of the mammary shape by use of breast reduction techniques (volume displacement) or tissue replacement techniques (volume replacement) is gaining popularity to prevent breast malformation. Methods To date, using the internal mammary artery perforator (IMAP) flap has been suggested for immediate volume replacement after WLE, but has never been evaluated in a published study. Results We applied this flap in 12 women (mean age, 56.1 years) after WLE (mean specimen weight, 46.5 g) of the medial aspect of the breast. Over a median follow-up of 35.3 months (standard deviation, 1.2 months), 4 women needed repeated surgery for dog-ear correction of the donor site. Conclusions In our experience, the use of an IMAP flap was a reliable technique with good cosmetic outcomes after oncoplastic reconstruction. In this series, donor site revision often proved necessary initially, but we showed that this may easily be prevented.

Background: Breast conservative surgery (BCS) followed by radiotherapy is the standard approach in management of stage I-II breast cancer. Several factors can affect cosmetic outcomes. The aim of this study was to evaluate the cosmetic results of BCS and influencing factors in the Iranian Breast Cancer Research Center. Materials and Methods: Patients who had undergone BCS were included. Photographs were taken of both breasts of the patients in three aspects and were evaluated by three specialists. The cosmetic scores were calculated based on a standard questionnaire. The data were analyzed using univariate and multivariate regression for relationships between cosmetic scores and clinical data. Results: A total number of 103 patients were included in the study. Mean age and BMI of the patients were $46.8{\pm}8.9$ and $28.1{\pm}3.9$, respectively. Breast cup sizes C and D accounted for 74.7% of the study group. The mean cosmetic score obtained from three referees was 5.72+2.06, consisting of 35.9% excellent-good, 35% moderate, and 29.1% unsatisfactory results. Patient BMI, volume of the resected tissue and breast cup size (D) showed significant correlation with the cosmetic score. On multivariate regression analysis, cosmetic score and BMI (p=0.022,) as well as breast cup size (p=0.040), remained significant. Conclusions: Immediate or delayed symmetrization of the breasts is suggested during breast conservative surgery, meanwhile performing oncoplastic techniques to improve the results significantly. Also it is suggested to discuss anticipation of less satisfactory results with patients having higher BMI and large breast cup size.

Background Perforator artery flaps based on the branches of intercostal arteries and lateral thoracic artery can be used for reconstruction after breast-conserving surgery (BCS). Although described more than a decade ago, these have not been adopted widely in clinical practice. We report on short-term and long-term surgical outcomes of partial breast reconstruction using chest wall perforator flaps from a prospective multicenter audit. Methods All patients operated for BCS and partial breast reconstruction using intercostal artery perforator or lateral thoracic artery perforator flaps from January 2015 to October 2018 were included in the analysis. Oncoplastic breast surgeons with appropriate level of training performed all tumor excisions and reconstructions as a single-stage procedure. Patient characteristics, treatment details and surgical outcomes were noted. Specific outcomes recorded were margin re-excision and complication rates. Results One hundred and twelve patients underwent the procedure in the given study period. The median age was 54 years. Median specimen weight was 62.5 g and median volume of excision was 121.4 mL. Fifteen patients (13.39%) underwent a margin re-excision for close or positive margins without additional morbidity. One patient required a completion mastectomy. Eight patients (7.14%) had an early complication. None of the patients required a contralateral symmetrization procedure. The results were comparable across the participating centers. Conclusions Chest wall artery perforator-based flaps are an excellent option for lateral and inferior quadrant partial breast reconstructions. The short and long-term surgical outcomes are comparable across sites and can be performed with minimal morbidity. Patient-reported outcome measures need to be studied.

Background Several oncoplastic approaches have been implemented in recent years to enhance cosmetic results and to reduce complications. The round block technique is a volume displacement technique for breast reconstruction after breast-conserving surgery (BCS). However, its indications are currently limited according to tumor location, and its cosmetic results and complications have not been clearly established. We hypothesized that the round block technique could produce favorable cosmetic results without major complications regardless of tumor location or nipple-tumor distance, below a certain resected tumor volume and tumor-breast volume ratio. Methods All breast reconstructions using the round block technique after BCS were included in this analysis. Patients' data were reviewed retrospectively to investigate complications during follow-up, and clinical photos were used to evaluate cosmetic results. The relationships of tumor location, nipple-tumor distance, tumor volume, and the tumor-breast volume ratio with cosmetic results were investigated. Results In total, 108 breasts were reconstructed. The mean resected tumor volume was 30.2±15.0 mL. The cosmetic score was 4.5±0.6 out of 5. Tumor location, nipple-tumor distance, tumor volume, tumor-breast volume ratio, radiotherapy, and chemotherapy had no significant effects on cosmetic results or complications. There were no major complications requiring reoperation. Conclusions Breast reconstruction using the round block technique after BCS can lead to good cosmetic results without major complications regardless of the tumor location, nippletumor distance, radiotherapy, or chemotherapy. Below the maximum tumor volume (79.2 mL) and the maximum tumor-breast volume ratio (14%), favorable results were consistently obtained.

Capsular contracture is the most common complication following implant based breast surgery and is one of the most common reasons for reoperation. Therefore, it is important to try and understand why this happens, and what can be done to reduce its incidence. A literature search using the MEDLINE database was conducted including search terms 'capsular contracture breast augmentation', 'capsular contracture pathogenesis', 'capsular contracture incidence', and 'capsular contracture management', which yielded 82 results which met inclusion criteria. Capsular contracture is caused by an excessive fibrotic reaction to a foreign body (the implant) and has an overall incidence of 10.6%. Risk factors that were identified included the use of smooth (vs. textured) implants, a subglandular (vs. submuscular) placement, use of a silicone (vs. saline) filled implant and previous radiotherapy to the breast. The standard management of capsular contracture is surgical via a capsulectomy or capsulotomy. Medical treatment using the off-label leukotriene receptor antagonist Zafirlukast has been reported to reduce severity and help prevent capsular contracture from forming, as has the use of acellular dermal matrices, botox and neopocket formation. However, nearly all therapeutic approaches are associated with a significant rate of recurrence. Capsular contracture is a multifactorial fibrotic process the precise cause of which is still unknown. The incidence of contracture developing is lower with the use of textured implants, submuscular placement and the use of polyurethane coated implants. Symptomatic capsular contracture is usually managed surgically, however recent research has focussed on preventing capsular contracture from occurring, or treating it with autologous fat transfer.
