RESUMO
BACKGROUND: The prognosis in patients with breast cancer with isolated locoregional recurrence (ILRR) without simultaneous distant metastases after immediate breast reconstruction (IBR) remains unknown. We aimed to investigate the prognosis in this patient population. METHODS: This multi-institutional retrospective observational study evaluated 3295 patients with primary breast cancer who underwent IBR at 12 Japanese medical facilities between January 1, 2008 and December 31, 2016. The outcome measures were the prognostic factors for ILRR after IBR, 5-year distant metastasis-free interval (DMFI), and 5-year overall survival (OS). RESULTS: Mastectomy or skin-sparing mastectomy was performed in 3295 patients. ILRR occurred in 70 patients, and the median observation period from ILRR diagnosis was 39.3 months. Of the 70 patients, 9 (12.9%) had axillary lymph node recurrence (ALNR) at the time of ILRR diagnosis. The 5-year DMFI and OS rates after ILRR were 92.4% and 91.2%, respectively. Pathological lymph node metastasis at primary surgery (P = 0.041) and ALNR (P = 0.022) at ILRR were significantly associated with DMFI in the univariate analysis. ALNR was the only independent prognostic factor in the multivariate analysis (P = 0.041). Post-mastectomy radiation therapy (PMRT; P = 0.022) and ALNR (P = 0.043) were significantly associated with OS in the univariate analysis, and both PMRT (P = 0.010) and ALNR (P = 0.028) were independent prognostic factors in the multivariate analysis for OS. CONCLUSIONS: Although patients with breast cancer who had ILRR after IBR have favorable prognosis, ALNR may lead to poor prognosis. To the best of our knowledge, this study is the first to report the prognosis of these patients.

INTRODUCTION: Involved surgical margins are risk factors for local recurrence and re-excision is often difficult, particularly in patients with breast cancer undergoing immediate breast reconstruction (IBR). However, the magnitude of the effect of radiation therapy on preventing local recurrence for breast cancers with involved margins has not been sufficiently assessed. MATERIALS AND METHODS: We retrospectively assessed sites of involved surgical margins and local recurrence after mastectomy with IBR in patients with early breast cancer between 2008 and 2016. The effect of postoperative radiation therapy was evaluated in patients with involved margins, adjusted for nuclear grade, lymphatic invasion, surgical procedures, and primary systemic therapy. RESULTS: A total of 274 (5.8 %) out of 4726 patients who underwent mastectomy with IBR had involved surgical margins: 133, 68, 88, and 26 had involvement of the skin, deep margin, lateral margins, and nipple, respectively (including duplicates). Radiation therapy was administered to 54 patients with involved margins. In patients with involved margins, 7-year cumulative incidences of local recurrence were 1.9 % and 12.6 % with and without radiation therapy, respectively (adjusted hazard ratio, 0.17; 95 % CI, 0.04-0.80). Local recurrence occurred in 28 patients, and the sites were skin, subcutaneous tissue, muscle, and nipple-areola complex in 7, 17, 1, and 3 patients, respectively. Among them, 23 (82.1 %) were associated with involved margin sites. CONCLUSIONS: Radiation therapy meaningfully reduced the incidence of local recurrence in patients with breast cancer with margin involvement after mastectomy with IBR. Most local recurrences occurred at involved margin-related sites.

BACKGROUND: Position of the nipple-areolar complex (NAC) is an important factor in the esthetic impression of the breast, and NAC malposition is often an issue in breast reconstruction after nipple-sparing mastectomy (NSM). The purpose of this study was to evaluate the degree of NAC malposition depending on several factors using data quantified with the Mamma Balance application (Medic Engineering K.K., Kyoto, Japan). METHODS: Patients who underwent unilateral breast reconstruction after NSM at eight hospitals in Japan between 2007 and 2020 were retrospectively investigated. Using Mamma Balance, NAC malposition was quantified separately in horizontal and vertical directions using patient photographs from pre-operatively and 6-24 months post-operatively. The degree of malpositioning was then statistically compared using various factors. RESULTS: The NAC deviated more cranially and medially with implants than that with flaps. Cases with latissimus dorsi flap showed lateral malposition more often than cases with deep inferior epigastric artery perforator flap. With flaps, lateral incisions showed more lateral malposition, and peri-areolar incisions tended to show more medial NAC malposition. In cases with severe post-operative infection of the implant, the NAC tended to deviate cranially. In radiation cases, the NAC deviated cranially. No significant difference was observed according to the degree of breast ptosis or use of the pull-down operation. Only a very weak correlation was observed between a larger amount of mastectomy and more cranial NAC malposition with both flaps and implants. CONCLUSIONS: This study provides insights into the tendencies and characteristics of NAC malposition.

Background: Clinical nursing competence includes ethics, cooperation with other professionals, and management, in addition to nursing abilities and responding per situation. Therefore, it may vary depending on one's experience and the work environment. However, there is a lack of studies exploring the competence for different experience levels. Therefore, this study aimed to clarify the association between clinical nursing competence and the work environment by experience groups. Methods: Anonymous self-administered questionnaire surveys were conducted on 717 nurses in regional core hospitals from December 2017 to March 2018. Clinical nursing competence was measured using the Clinical Nursing Competence Self-Assessment Scale (CNCSS). Association of CNCSS with experience and work environment was examined. Results: Responses from 231 nurses with 1-10 years of experience were analyzed. Compared with those in the 2-year experience group, those in the 3-5- and 6-10-year experience groups assessed their "planned development of nursing care" and "assessment of care" competencies to be higher. Additionally, compared with those in the 2-year experience group, those in the 6-10-year experience group assessed their "clinical judgment" and "care coordination" competencies to be higher. Nurses with 1 year of experience showed significant positive correlations between clinical nursing competence and "good interpersonal relationship," "clarity about the organization's vision," and "ease of taking time off"; and those with 6-10 years of experience showed significant positive correlations between clinical nursing competence and "support from superiors and senior coworkers" and "established and easily accessible support system for taking time off for childcare and caregiving." Conclusion: The relationship between clinical nursing competence and the work environment differed according to years of experience. Interventions to improve clinical nursing competence should be developed for each experience group considering the associations.
RESUMO
Although immediate breast reconstruction following mastectomy has become increasingly common, its oncological safety has been debated. We enrolled patients with breast cancer who underwent surgery at Okayama University Hospital between 2007 and 2013. The primary outcome was relapse-free survival (RFS). Secondary outcomes were overall survival and the duration from the surgery to the initiation of adjuvant chemotherapy. We divided into immediate breast reconstruction, mastectomy alone, and breast conservative surgery groups. Outcomes were compared using Cox's regression analysis. A total of 614 patients were included (reconstruction: 125, mastectomy: 128, breast conservative surgery: 361). The median follow-up duration was 79.0±31.9 months. The immediate-reconstruction patients were younger, had more lymph node metastases, and more often received postoperative chemotherapy. The RFS was better after the breast conservative surgery compared to after reconstruction (hazard ratio 0.33, 95% confidence interval: 0.144-0.763). The proportion of local recurrence was highest in the reconstruction group. No patients in the reconstruction group underwent postoperative radiation therapy. However, reconstruction did not affect overall survival or the time to the initiation of adjuvant chemotherapy. Surgeons should explain the risks of breast reconstruction to their patients preoperatively. Careful long-term follow-up is required after such procedures.

PURPOSE: Perioperative inflammatory cytokines may be related to cancer proliferation, although few studies have investigated this issue in patients undergoing breast reconstruction surgery. METHODS: We conducted a prospective study of patients scheduled for mastectomy only, mastectomy plus deep inferior epigastric perforator flap reconstruction (DIEP), or mastectomy plus tissue expander reconstruction (TE), with or without axial dissection (Ax), for primary breast cancer. Blood samples were collected for analysis of serum IL-6 and VEGF preoperatively, then within 24 h postoperatively (POD 1), and 4-6 days postoperatively (POD 4-6). We investigated the difference in serum cytokine levels over time for each surgical procedure and the difference in serum cytokine levels among the procedures at the three measurement time points. RESULTS: There were 120 patients included in the final analysis. Serum IL-6 was significantly higher than the preoperative level on POD 1 in patients who underwent mastectomy only, DIEP, or TE and Ax (+), with higher values persisting on POD 4-6 except in those who underwent DIEP. IL-6 was significantly higher after DIEP than after mastectomy only on POD 1, but no differences were observed at POD 4-6. VEGF did not differ significantly among the surgical procedures at any time. CONCLUSIONS: The increase in IL-6 was short term and immediate breast reconstruction is considered a safe procedure.

Breast reconstruction (BR) aims to improve the satisfaction and quality of life (QOL) of breast cancer survivors. Clinical studies using patient-reported outcomes (PROs) can therefore provide relevant information to the patients and support decision-making. This scoping review was conducted to analyze recent trends in world regions, methods used, and factors investigated. The literature search was conducted in August 2022. Databases of PubMed, MEDLINE, and CINAHL were searched for relevant English-language studies published from 2017 to 2022. Studies involving women with breast cancer who underwent BR after mastectomy and investigated PROs after BR using BR-specific scales were included. Data on the country, publication year, study design, PRO measures (PROMs) used, time points of surveys, and research themes were collected. In total, 147 articles met the inclusion criteria. BREAST-Q was the most widely used, contributing to the increase in the number and diversification of studies in this area. Such research has been conducted mainly in North America and Europe and is still developing in Asia and other regions. The research themes involved a wide range of clinical and patient factors in addition to surgery, which could be influenced by research methods, time since surgery, and even cultural differences. Recent BR-specific PROMs have led to a worldwide development of research on factors that affect satisfaction and QOL after BR. PRO after BR may be influenced by local cultural and social features, and it would be necessary to accumulate data in each region to draw clinically useful conclusion.

The importance of a well-fitted, comfortable brassiere to overall quality of life after breast reconstruction has not been evaluated. Our aim was to determine the impact of a semi-customized brassiere on patients' health-related quality of life after breast reconstruction. The subjects were prospective patients with mastectomy who were to undergo immediate or delayed breast reconstruction at our hospital. After surgery, a professional bra fitter sized each patient for a semi-customized brassiere and provided follow-up consultations. A self-reported questionnaire on breast aesthetics, postoperative pain, and satisfaction was used to assess the primary outcomes. Data were prospectively collected at baseline (before surgery) and at 1, 3, 6, and 12 months after surgery and analyzed. Forty-six patients (50 breasts) were included in the analysis. Consistent wearing of the brassiere reduced pain (p<0.05), with good overall satisfaction (p<0.001). Aesthetic scores on breast shape and size were higher with than without the custom brassiere at 3 months (p=0.02) and 6 months (p=0.03) after surgery. Wearing the brassiere reduced anxiety at all time points of measurement. A well-fitting brassiere ensured safety and provided a high degree of satisfaction without anxiety for patients after breast reconstruction.

BACKGROUND: One barrier to the widespread use of breast reconstruction (BR) is physicians' perception that BR adversely affects breast cancer prognosis. However, there is limited information regarding physicians' understanding of the impact of BR on patient prognosis and which physicians have misunderstandings about BR. METHODS: We conducted an e-mail survey regarding the impact of BR on the prognosis of patients with breast cancer among members of the Japanese Breast Cancer Society. RESULTS: Of 369 respondents, 99 (27%) said that they believe BR affects patient prognosis. Female respondents and those who treat fewer new breast cancer patients per year were more likely to state that they believe BR affects patient prognosis (P = 0.006 and 0.007). Respondents who believed that BR affects patient prognosis underestimated 5-year overall survival rates in patients who receive BR and subsequently have local or regional recurrence in different sites. CONCLUSION: Our survey demonstrated that a quarter of respondents believe that BR affects patient prognosis and underestimate survival rates in patients who receive BR and have subsequent local or regional recurrence. Because of the lack of evidence regarding the impact of BR on patient prognosis, educating physicians by providing accurate knowledge regarding BR and patient prognosis is highly recommended.

INTRODUCTION: The aim of breast reconstruction (BR) is to improve patients' health-related quality of life (HRQOL). Therefore, measuring patient-reported outcomes (PROs) would clarify the value and impact of BR on a patient's life and thus would provide evidence-based information to help decision-making. The Satisfaction and Quality of Life After Immediate Breast Reconstruction study aimed to investigate satisfaction and HRQOL in Japanese patients with breast cancer who undergo immediate breast reconstruction (IBR). METHODS AND ANALYSIS: This ongoing prospective, observational multicentre study will assess 406 patients who had unilateral breast cancer and underwent mastectomy and IBR, and were recruited from April 2018 to July 2019. All participants were recruited from seven hospitals: Okayama University Hospital, Iwate Medical University Hospital, The Cancer Institute Hospital of Japanese Foundation for Cancer Research, Showa University Hospital, University of Tsukuba Hospital, Osaka University Hospital and Yokohama City University Medical Center. The patients will be followed up for 36 months postoperatively. The primary endpoint of this study will be the time-dependent changes in BREAST-Q satisfaction with breast subscale scores for 12 months after reconstructive surgery, which will be collected via an electronic PRO system. ETHICS AND DISSEMINATION: This study will be performed in accordance with the Ethical Guidelines for Medical and Health Research Involving Human Subjects published by Japan's Ministry of Education, Science and Technology and the Ministry of Health, Labour and Welfare, the modified Act on the Protection of Personal Information and the Declaration of Helsinki. This study protocol was approved by the institutional ethics committee at the Okayama University Graduate School of Medicine, Dentistry, on 2 February 2018 (1801-039) and all other participating sites. The findings of this trial will be submitted to an international peer-reviewed journal. TRIAL REGISTRATION NUMBER: UMIN000032177.

BACKGROUND: An understanding of health-related quality of life (HRQOL) is of utmost importance in both oncological and esthetic breast surgery. The BREAST-Q is a patient-reported outcome (PRO) measure that investigates HRQOL and patient satisfaction before and after breast surgery. The aim of this study was to develop a Japanese version of the BREAST-Q including the mastectomy module, the reconstruction module, the augmentation module and the reduction/mastopexy module, and to assess the psychometric properties of the mastectomy module among Japanese women. METHODS: The Japanese version of the BREAST-Q was developed through forward translation, backward translation and patient testing. Traditional psychometric testing of the mastectomy module was administered to 45 post-mastectomy patients. RESULTS: The mastectomy, reconstruction, augmentation and reduction/mastopexy modules were formally developed into Japanese. Despite cultural difference between Japanese women and original target population, the contents were considered to be valid among Japanese woman. With the exception of the sexual well-being subscale, good reliability and validity were evident for the mastectomy module (Test-retest reliability 0.76-0.95, Chronbach's alpha coefficient 0.77-0.98). CONCLUSIONS: The BREAST-Q Japanese version is a useful PRO measure for investigating the impact of breast surgery on HRQOL and patient satisfaction. Further validation in younger Japanese women is needed to determine the usefulness of the sexual well-being subscale.
