Purpose: To review the impact of using intra-operative ultrasound guided breast conserving surgery with frozen sections on final pathological margin outcome with the current guidelines set forth by the Society of Surgical Oncology (SSO) and the American Society of Surgical Oncology (ASTRO). Materials and Methods: A retrospective review including all cases of intra-operative ultrasound guided breast conserving surgery was performed at the National Cancer Institute Thailand between 2013 and 2016. Patient demographics, tumor variables, intraoperative frozen section and final pathological margin outcomes were collected. Factors for positive or close margins were analyzed. Results: A total of 86 patients aged between 27 and 75 years with intra-operative ultrasound guided breast conserving surgery were included. Three cases (3.5%) of positive margin were detected by intra-operative frozen section and 4 cases (4.7%) by final pathology reports. There were 18 cases (20.9%) with a close margin (<1 mm). Factors affecting this result comprised multi-foci, presence of invasive ductal carcinoma (IDC) combined with ductal carcinoma in situ (DCIS) and invasive lobular carcinoma (ILC). Conclusions: With the current SSO/ASTRO for adequate margin guidelines, using intra-operative ultrasound to locate the boundary for resection with breast conserving surgery provided a high success rate in obtaining final pathology free margin outcomes and minimizing re-operation risks especially when combined with intra-operative frozen section assessment. The chance of finding positive or close margins appears higher in cases of IDC combined with DCIS, ILC and with multi-foci cancers.

Background: There are limited studies on oncoplastic breast conserving surgery in Asian women. We aimed to determine the applicability and safety of oncoplastic surgery, highlighting the specific circumstances when it will be most useful and compare our preferred technique with the worldwide practice of oncoplastic approaches. Materials and Methods: Breast cancer patients who underwent oncoplastic breast conserving surgery at a single institution from 1st May 2014-31st March 2015 were included. Data on patient demographics, tumor characteristics and the type of oncoplastic surgery performed were collected. Results: Nineteen breast cancer patients were identified. 42.1% of patients had grade I ptosis. The indications for surgery included a large tumor to breast size ratio (52.6%), multifocal/multicentric lesions (36.8%) and asymmetric breasts (10.6%), averting a mastectomy in 89.4%. Round block was the commonest technique in 63% of patients, in contrast to the inverted T pattern most frequently used in renowned institutions in the West. Mean and median tumor size and weight of specimen were 29.4/25mm (11 - 75mm) and 77g/64g (10 - 246g) respectively. Re-excision rate was 10.5%. Complete mastectomy was performed for one patient. One patient developed wound dehiscence which was treated conservatively. Cosmetic outcome was rated as excellent/good by 94.7% of patients. The patients remained clinically well after a median 16 months follow up. Conclusions: Oncoplastic breast conserving surgery is useful in a specific subgroup of Asian patients with a relatively small breast volume and minimal ptosis. Round block was the commonest technique in our series, in contrast to the worldwide utility of oncoplastic techniques. It is oncologically safe and has good cosmetic outcomes.

Background Breast-conserving surgery is widely accepted as an appropriate method in breast cancer, and the lateral thoracodorsal flap provides a simple, reliable technique, especially when a mass is located in the lateral breast. This study describes the usefulness of a lateral thoracodorsal flap after breast conserving surgery in laterally located breast cancer. Methods From September 2008 to February 2013, a lateral thoracodorsal flap was used in 20 patients with laterally located breast cancer treated at our institution. The technique involves a local medially based, wedge shaped, fasciocutaneous transposition flap from the lateral region of the thoracic area. Overall satisfaction and aesthetic satisfaction surveys were conducted with the patients during a 6-month postoperative follow-up period. Aesthetic results in terms of breast shape and symmetry were evaluated by plastic surgeons. Results The average specimen weight was 76.8 g. The locations of the masses were the upper lateral quadrant (n=15), the lower lateral quadrant (n=2), and the central lateral area (n=3). Complications developed in four of the cases, partial flap necrosis in one, wound dehiscence in one, and fat necrosis in two. The majority of the patients were satisfied with their cosmetic outcomes. Conclusions Partial breast reconstruction using a lateral thoracodorsal flap is well matched with breast color and texture, and the surgery is less aggressive than other techniques with few complications. Therefore, the lateral thoracodorsal flap can be a useful, reliable technique in correcting breast deformity after breast conserving surgery, especially in laterally located breast cancer.

본 연구는 유방 보존술(68명)과 유방 전절제술(45명)을 받은 대상자의 수술 후 심신의 변화에 따른 의생활의 공통점과 차이점에 대하여 조사하였다. 공통점으로는 유방 절제 수술로 변형된 체형을 노출시키고 싶어 하지 않았고, 타인에게 본인이 유방암 환자인 것을 알아채주어 배려 해 주기를 바라지 않는 것으로 확인되었다. 그러므로 유방 절제 범위가 큰 유방 전절제술의 대상자는 신체 이미지의 고양을 위하여 절제된 유방의 보완이 가능한 의복 및 보조물(인조 유방)을 선호하였다. 그러나, 유방 전절제술을 받은 대상자를 위한 브래지어나 인조유방은 고가임은 물론, 낮은 감성 만족도를 나타내었고, 특히 유방암 수술을 받은 대상자들을 위한 전문 의복이 필요하다고 응답하였다. 향후, 유방 절제 수술을 받은 한국 여성 대상자를 위한 치유 복장, 브래지어나 인조유방 등의 개발에 있어, 이와 같은 감성 조사가 효과적인 정보 자료로 사용 되어 신체이미지 증진은 물론 삶의 질 향상에 도움이 될 것을 기대한다.

Objective: To compare the influence of breast-conserving surgery (BCS) and modified radical mastectomy (MRM) on the psychological state of breast cancer patients. Methods: Patients receiving MRM or BCS, and fulfilling the study criteria, were recruited. Patients were required to complete a self-reporting inventory (SCL-90) on admission and 6 months after surgery and a self-rating depression scale (SDS) when discharged from hospital and 6 months after surgery. Results: A total of 70 patients received MRM and 50 BCS. Compared with the national standard, patients suffered to some extent psychological problems on admission, at discharge from hospital and at 6 months after surgery. Patients received BCS had a higher score of SDS compared with those with MRM when discharged from hospital. However, 6 months after surgery, SDS score increased in MRM and decreased in the BCS group, so the difference was significant. Conclusion: The short-term psychological state of patients receiving BCS is worse than that with MRM but superior to MRM 6 months postoperatively. BCS imposed less influence on long term psychological state of breast cancer patients compared with MRM.

Purpose: To evaluate the necessity of regional nodal irradiation (RNI) for pT1-2N1 breast cancer patients treated with breast-conserving surgery and radiotherapy, we compared clinical outcomes of patients treated with and without RNI. Materials and Methods: We retrospectively analyzed the data of 214 pT1-2N1 breast cancer patients treated with breast-conserving surgery and whole breast irradiation from 2007-2016. There were 142 (66.4%), 51 (23.85%), and 21 (9.8%) patients with one, two, and three positive lymph nodes, respectively. Thirty-six patients (16.8%) underwent RNI. Adjuvant chemotherapy, endocrine therapy, and anti-HER2 therapy were given to 91.6%, 79.0%, and 15.0% patients, respectively. The most common chemotherapy regimen was anthracycline + cyclophosphamide, followed by taxane (76.5%). The median follow-up was 64 months (range, 6 to 147 months). Patients were propensity matched 1:2 into RNI and no-RNI groups. Results: Two patients experienced locoregional recurrences simultaneously with distant metastases, ten patients developed distant metastases, and one patient died. Before matching, the 5-year actuarial locoregional control (LRC), distant metastasis-free survival (DMFS), and overall survival (OS) rates in the RNI and no-RNI groups were 100.0% and 99.4% (p = 0.629), 94.1% and 96.0% (p = 0.676), and 100.0% and 99.4% (p = 0.658), respectively. After matching, the 5-year LRC, DMFS, and OS were 98.3% and 100.0% (p = 0.455), 96.6% and 93.9% (p = 0.557), and 100.0% and 100.0% (p > 0.999) in the RNI and no-RNI groups, respectively. No clinicopathologic or treatment-related factors were significantly associated with LRC, DMFS, or OS. Conclusion: Adding RNI did not show superior LRC, DMFS, or OS in pT1-2N1 breast cancer patients.

A compariosn was made of survival outcomes of oncoplastic breast conserving therapy (oBCT) with nipple-areolar (NAC) preservation in women with centrally located breast cancer (CLBC) undergoing modified radical mastectomy (MRM) in China in a matched retrospective cohort study. We used a database including patients who received oBCT (n=91) or MRM (n=182) from 2003 to 2013 in our hospital. Matching was conducted according to five variables: age at diagnosis, axillary lymph node status, hormone receptor status, human epidermal growth factor-like receptor 2 status (HER-2) and tumor stage. The match ratio was 1:2. Median follow-up times for the oBCT and MRM groups were 83 and 81 months, respectively. There were no significant differences in 87-month overall, local, or distant recurrence-free survival between patients with oBCT and MRM (89%vs.90%; 93%vs.95%; 91%vs.92%;). For appropriate breast cancer patients, oBCT for CLBC is oncologically safe, oncoplastic techniques improving cosmetic outcomes.

Purpose: The aim of this study was to investigate the differences in quality of life in patients who received breast conserving surgery (BCS) or modified radical mastectomy (MRM) for breast cancer. Materials and Methods: A total of 100 women with breast cancer who underwent either BCS or MRM between September 2011 and April 2012 at a private health center and completed their chemotherapy and radiation therapy cycles were included in the study. To assess the quality of life, we used a demographic questionnaire, the European Organization for the Research and Treatment of Cancer Quality of Life Questionnaire (EORTC QLQ-C30) and the Quality of Life assessment in Breast Cancer (EORTC QLQ-BR23). Results: Using QLQ-C30, we found that patients who underwent BCS had better functional status and fewer symptoms than patients who underwent MRM. In QLQ-BR23, independent factors improving the functional scales were BCS, higher level of education and marital status (married); independent factors improving symptoms were BCS, higher level of education, younger age and low and normal body mass index (BMI). In QLQ-C30, independent factors affecting the functional and symptom scales were only BCS and higher level of education. Conclusions: We determined that patients who received BCS had better functional status and less frequent symptoms than patients who underwent MRM.

Background In Korean women, many of whom have small to moderate-sized breasts, it is difficult to cover a partial breast defect using oncoplastic volume displacement techniques after removal of an adequate volume of tissue during oncologic surgery. In such cases, oncoplastic volume replacement techniques are more useful. Methods From January 2007 to December 2011, 104 women underwent a total of 107 breast-conserving surgeries with various kinds of oncoplastic volume replacement techniques. We used latissimus dorsi (LD) myocutaneous flap for cases in which the resection mass was greater than 150 g. In case with a resection mass less than 150 g, we used regional flaps such as a lateral thoracodorsal flap, a thoracoepigastric flap, or perforator flaps such as an intercostal artery perforator (ICAP) flap or a thoracodorsal artery perforator (TDAP) flap. Results The mean age was 46.1 years, and the average follow-up interval was 10.3 months. The patients underwent oncoplastic volume replacement techniques with a lateral thoracodorsal flap (n=9), thoracoepigastric flap (n=7), ICAP flap (n=25), TDAP flap (n=12), and LD flap (n=54). There was one case of congestion in an LD flap, and two cases of fat necrosis in an ICAP flap. Most of the patients were satisfied with the cosmetic results. Conclusions Oncoplastic volume replacement techniques can be reliable and useful for the correction of breast deformity after breast-conserving surgery, especially in patients with small to moderate-sized breasts.

Background: The National Breast Cancer Audit Database of the Society of Breast Surgeons of Australia and New Zealand is used by surgeons to monitor treatment quality and for research. About 60% of early invasive female breast cancers in Australia are recorded. The objectives of this study are: (1) to investigate associations of socio-demographic, health-system and clinical characteristics with treatment of invasive female breast cancer by mastectomy compared with breast conserving surgery; and (2) to consider service delivery implications. Materials and Methods: Bi-variable and multivariable analyses of associations of characteristics with surgery type for cancers diagnosed in 1998-2010. Results: Of 30,299 invasive cases analysed, 11,729 (39%) were treated by mastectomy as opposed to breast conserving surgery. This proportion did not vary by diagnostic year (p>0.200). With major city residence as the reference category, the relative rate (95% confidence limits) of mastectomy was 1.03 (0.99, 1.07) for women from inner regional areas and 1.05 (1.01, 1.10) for those from more remote areas. Low annual surgeon case load (${\leq}10$) was predictive of mastectomy, with a relative rate of 1.08 (1.03, 1.14) when compared with higher case loads. Tumour size was also predictive, with a relative rate of 1.05 (1.01, 1.10) for large cancers (40+ mm) compared with smaller cancers (<30 mm). These associations were confirmed in multiple logistic regression analysis. Conclusions: Results confirm previous studies showing higher mastectomy rates for residents of more remote areas, those treated by surgeons with low case loads, and those with large cancers. Reasons require further study, including possible effects of surgeon and woman's choice and access to radiotherapy services.
