乳房切除术
  • 文章类型: Journal Article
    背景:性别确认乳房切除术(GAM)可改善跨性别和非双性恋(TGNB)个体的心理社会功能和生活质量。然而,围手术期通常以情绪压力为标志,对手术结果的担忧,和身体不适。虽然住院手术提供了与患者互动和教育的多种机会,门诊手术,比如GAM,由于患者术后随访<24小时,因此构成了独特的挑战。鉴于TGNB个体经常经历的与性别焦虑相关的情绪和心理困扰加剧,解决这些差距可以显着改善结果。这项研究旨在表征该人群中与患者发起的沟通(PIC)频率相关的患者和手术特征。方法:对2018年2月至2022年11月接受GAM的TGNB患者进行单中心回顾性分析。人口统计,手术特点,记录围手术期PIC的频率和原因(手术前后30天)。主要结果是围手术期PIC的发生率。次要结果包括(1)PIC的基本原理和(2)患者和与PIC相关的手术特征。结果:共纳入352例患者。其中,285(74.6%)在围手术期开始沟通,总共659个PIC。中位年龄为25.0岁(四分位距[IQR]:9.0)。中位体重指数(BMI)为28.5(IQR:8.5)kg/m2。术前平均PIC数为0.7±1.3,术后为1.3±1.7(p<0.001)。术前PIC受试者最常见的是行政问题(AI;n=66,30.7%),术前要求(n=43,20.0%),以及成本和保险(n=33,15.0%)。术后最常见的PIC受试者是伤口护理(n=77,17.3%),AI(n=70,15.0%),活动限制(n=60,13.5%),排水量(n=56,12.6%),和肿胀(n=37,8.3%)。总的来说,老年患者(β=0.234,p=0.001),有重度抑郁症或广泛性焦虑症病史的人(2.4±3.0vs.1.7±1.9;p=0.019),和那些没有术后引流(n=16/17,94.1%vs.n=236/334,70.7%;p=0.025)从事更高水平的PIC。其他患者特征之间没有显著关联,围手术期细节,或并发症和PIC频率。结论:围手术期PIC在我们机构的大多数GAM患者中普遍存在,随着年龄,精神病诊断,术后引流使用被确定为重要的预测因素。为了减轻PIC频率,确保足够的支持人员和提供全面的术后指导至关重要,特别是关于活动限制和排水管理。这些干预措施可能会减少高容量中心的PIC。进一步的研究应探讨有针对性的干预措施,以进一步支持TGNB患者围手术期。
    Background: Gender-affirming mastectomy (GAM) improves the psychosocial functioning and quality of life of transgender and non-binary (TGNB) individuals. However, the perioperative period is often marked by emotional stress, concerns about surgical outcomes, and physical discomfort. While inpatient procedures provide multiple opportunities to engage with and educate patients, outpatient surgeries, such as GAM, pose a unique challenge as patients are followed for <24 h postoperatively. Given the heightened emotional and psychological distress related to gender dysphoria TGNB individuals often experience, addressing these gaps can significantly improve outcomes. This study aims to characterize patient and surgical characteristics associated with patient-initiated communication (PIC) frequency in this population. Methods: A single-center retrospective review of TGNB patients undergoing GAM from February 2018 to November 2022 was conducted. Demographics, surgical characteristics, and frequency of and reasons for perioperative PIC (30 days before and after surgery) were recorded. The primary outcome was the incidence of perioperative PIC. The secondary outcomes included (1) the rationale for PIC and (2) patient and surgical characteristics associated with PIC. Results: A total of 352 patients were included. Of these, 285 (74.6%) initiated communication in the perioperative period, totaling 659 PICs. The median age was 25.0 (interquartile range [IQR]: 9.0) years. The median body mass index (BMI) was 28.5 (IQR: 8.5) kg/m2. The mean number of PICs was 0.7 ± 1.3 preoperatively and 1.3 ± 1.7 postoperatively (p < 0.001). The most frequent preoperative PIC subjects were administrative issues (AI; n = 66, 30.7%), preoperative requirements (n = 43, 20.0%), and cost and insurance (n = 33, 15.0%). The most frequent postoperative PIC subjects were wound care (n = 77, 17.3%), AI (n = 70, 15.0%), activity restrictions (n = 60, 13.5%), drainage (n = 56, 12.6%), and swelling (n = 37, 8.3%). Collectively, older patients (β = 0.234, p = 0.001), those with a history of major depressive disorder or generalized anxiety disorder (2.4 ± 3.0 vs. 1.7 ± 1.9; p = 0.019), and those without postoperative drains (n = 16/17, 94.1% vs. n = 236/334, 70.7%; p = 0.025) engaged in higher levels of PIC. There were no significant associations between other patient characteristics, perioperative details, or complications and PIC frequency. Conclusions: Perioperative PIC is prevalent among the majority of GAM patients at our institution, with age, psychiatric diagnosis, and postoperative drain use identified as significant predictors. To mitigate PIC frequency, it is crucial to ensure adequate support staffing and provide comprehensive postoperative instructions, particularly concerning activity restrictions and drainage management. These interventions may reduce PICs in high-volume centers. Further research should investigate targeted interventions to further support TGNB patients during the perioperative period.

    背景与目的:乳腺分泌癌是一种少见的乳腺癌组织学亚型。关于这个实体的研究很少,只有一些更大的研究,缺乏共识。我们的目的是报告该亚型中特定的顶腺分泌分化,并考虑该病例的临床结果。病例介绍:我们报告了一名72岁女性患者的病例,该患者到我院就诊,患有可疑的乳腺肿瘤。核心活检和乳房切除术显示低度乳腺癌,一种分泌型亚型,具有大汗腺分化。免疫组织化学证实了肿瘤细胞的分泌性质和大汗腺性质。手术切除被认为是治愈性的,患者正在接受任何复发的长期监测。结论:对分泌性癌伴大汗腺分化的临床行为研究甚少。临床结果未知,不幸的是,除了手术,没有其他辅助治疗显示出疗效.对于这种罕见的实体,需要对长期临床进展进行进一步研究。
    Background and Objectives: Secretory carcinoma of the breast is an uncommon histological subtype of breast cancer. There is little research on this entity and only a few larger studies, which lack consensus. We aim to report a particular apocrine differentiation in this subtype and ponder upon the clinical outcome of this case. Case presentation: We report the case of a 72-year-old female patient who presented to our hospital with a suspicious breast tumor. Core biopsy and mastectomy showed a low-grade breast carcinoma, a secretory subtype with apocrine differentiation. Immunohistochemistry confirmed both the secretory nature and the apocrine nature of the tumor cells. Surgical excision was considered curative and the patient is under long-term surveillance for any recurrences. Conclusions: There is very little research on the clinical behavior of secretory carcinomas with apocrine differentiation. The clinical outcome is unknown and, unfortunately, besides surgery, no other adjuvant treatments have shown efficacy. Further studies on long-term clinical progression are required for this rare entity.

    (1)研究背景:乳腺癌是全球范围内的主要恶性肿瘤,在加纳,总体生存率很低。然而,大约50%的病例是早期疾病,随着乳腺癌治疗的进步和生存率的提高,生活质量(QOL)正变得与疾病的治疗一样重要。(2)方法:这是一项对接受保乳手术(BCS)的幸存者的横断面研究,2016年至2020年在加纳的一家三级医院进行的仅乳房切除术(M)和乳房再造乳房切除术(BRS),使用EORTCQLQC-30和EORTCQLQBR-23比较评估他们的生活质量。(3)结果:研究参与者的总体健康状况(GHS)中位数为83.3[IQR:66.7-91.7],手术类型之间没有显着差异。BRS组的功能量表中位数得分较低(82.8和51.0),症状量表得分最高(15.7和16.5)。BRS组的身体图像显着最低(83.3)[68.8-91.7],而BCS组的身体图像最高(100)[91.7-100](p<0.001)。(4)结论:有必要开发专门的支持系统,以改善乳腺癌幸存者的QOL,同时考虑所进行的手术类型。
    (1) Background: Breast cancer is the leading malignancy worldwide, and in Ghana, it has a poor overall survival rate. However, approximately 50% of cases are cases of early-stage disease, and with advances in breast cancer treatment and improvements in survival, quality of life (QOL) is becoming as important as the treatment of the disease. (2) Methodology: This was a cross-sectional study of survivors who had breast-conserving surgery (BCS), mastectomy only (M) and mastectomy with breast reconstruction (BRS) from 2016 to 2020 at a tertiary hospital in Ghana, comparatively assessing their QOL using EORTC QLQ C-30 and EORTC QLQ BR-23. (3) Results: The study participants had an overall global health status (GHS) median score of 83.3 [IQR: 66.7-91.7] with no significant differences between the surgery types. The BRS group had statistically significant lower median scores for the functional scale (82.8 and 51.0) and the highest scores for the symptomatic scale (15.7 and 16.5). Body image was significantly lowest for the BRS group (83.3) [68.8-91.7] and highest (100) [91.7-100] for the BCS group (p < 0.001). (4) Conclusion: There is a need to develop support systems tailored at improving the QOL of breast cancer survivors taking into consideration the type of surgery performed.

    多形性癌(PC)是一种罕见的高级乳腺癌形式,其特征是存在独特的多形性巨大肿瘤细胞,表现出奇异的核和非典型的有丝分裂。在这项研究中,我们报告了3例患者,他们在显微镜下出现了由大型多形性细胞增生组成的病变,其中多核巨细胞占优势。免疫组织化学分析显示,在各个恶性成分中具有不同的免疫学特征。值得注意的是,这份报告旨在提供有价值的见解,增加了对这种罕见肿瘤的理解,伴随着文献综述。尽管它很罕见,由于其独特的形态学和病理学特征,乳腺中的PC仍然具有临床相关性。这些独特的属性需要在临床表现和管理方面进行具体考虑。
    Pleomorphic carcinoma (PC) is an uncommon and high-grade form of breast carcinoma characterized by the presence of distinctive pleomorphic giant tumor cells exhibiting bizarre nuclei and atypical mitosis. In this study, we report three patients who presented with lesions composed of a proliferation of large pleomorphic cells with a predominance of multinucleated giant cells on a microscope. Immunohistochemical analysis revealed distinct immunologic profiles within the respective malignant components. Notably, this report aims to contribute valuable insights, adding to the understanding of this uncommon tumor, accompanied by a literature review. Despite its rarity, PC in the breast remains clinically relevant due to its distinctive morphological and pathological features. These unique attributes require specific considerations in both clinical presentation and management.

    背景:这项研究的目的是比较局部晚期乳腺癌患者的即时乳房重建(IBR)和单独乳房切除术的安全性和有效性结果。
    方法:我们对PUBMED进行了全面的文献检索,EMBASE,和Cochrane数据库。评估的主要结果是总生存率,无病生存,局部复发。次要结果是手术并发症的发生率。所有数据均使用ReviewManager5.3进行分析。
    结果:16项研究,本荟萃分析纳入了15,364名参与者.汇总数据表明,接受IBR的患者比仅接受乳房切除术的患者更容易出现手术并发症(HR:3.96,95CI[1.07,14.67],p=0.04)。总生存率无显著差异(HR:0.94,95CI[0.73,1.20],p=0.62),无病生存率(HR:1.03,95CI[0.83,1.27],p=0.81),或乳腺癌特异性生存率(HR:0.93,95CI[0.71,1.21],IBR组和非IBR组之间的p=0.57)。
    结论:我们的研究表明,乳房切除术后的IBR不影响局部晚期乳腺癌患者的总生存期和无病生存期。然而,IBR带来了不可忽视的更高的并发症风险,需要充分评估和仔细决定。
    BACKGROUND: The purpose of this study was to compare safety and efficacy outcomes between immediate breast reconstruction (IBR) and mastectomy alone in locally advanced breast cancer patients.
    METHODS: We conducted a comprehensive literature search of PUBMED, EMBASE, and Cochrane databases. The primary outcomes evaluated were overall survival, disease-free survival, and local recurrence. The secondary outcome was the incidence of surgical complications. All data were analyzed using Review Manager 5.3.
    RESULTS: Sixteen studies, involving 15,364 participants were included in this meta-analysis. Pooled data demonstrated that patients underwent IBR were more likely to experience surgical complications than those underwent mastectomy alone (HR: 3.96, 95%CI [1.07,14.67], p = 0.04). No significant difference was found in overall survival (HR: 0.94, 95%CI [0.73,1.20], p = 0.62), disease-free survival (HR: 1.03, 95%CI [0.83,1.27], p = 0.81), or breast cancer specific survival (HR: 0.93, 95%CI [0.71,1.21], p = 0.57) between IBR group and Non-IBR group.
    CONCLUSIONS: Our study demonstrates that IBR after mastectomy does not affect the overall survival and disease-free survival of locally advanced breast cancer patients. However, IBR brings with it a nonnegligible higher risk of complications and needs to be fully evaluated and carefully decided.

    在尼日利亚,乳房切除术是乳腺癌最常见的手术治疗方法。患者通常会入院几天,直到去除伤口引流。2017年在尼日利亚一家医院试行了一项早期出院计划,结果非常令人满意。该证据对临床实践和手术结果的影响在5年内进行了评估。
    来自前瞻性维护的机构数据库,获得了2018年至2022年间接受乳房切除术的患者的详细信息.每年获得并分析术后住院时间以确定趋势。手术后并发症,如血清肿,血肿,皮瓣坏死,并对手术部位感染进行了分析。
    总的来说,147例(69%)患者在复查期间有早期出院。22例(10.3%)患者在手术后24h内出院,61例(28.6%)在24-48h内出院,64名患者(30%)在48至72h之间出院。随着时间的推移,早期出院方案的采用稳步增加,2018年的采用率为50%,2022年为95%。平均住院时间从2018年的3.9天稳步下降到2022年的2.2天。早期出院不会对术后结果造成任何损害。
    这项研究表明,在资源有限的环境下,乳房切除术后早期出院的可持续性,结果非常令人满意。它还提供了一个独特的例子,说明本地生成的证据如何指导本地实践。我们认为这些发现在其他尼日利亚医院和具有类似背景的低收入和中等收入国家是可以推广的。
    UNASSIGNED: In Nigeria, mastectomy is the most common surgical treatment for breast cancer. Patients are often kept on admission for days until wound drains are removed. An early discharge programme was piloted in a Nigerian hospital in 2017 with very satisfactory outcomes. The impact of this evidence on clinical practice and surgical outcomes was evaluated over 5 years.
    UNASSIGNED: From a prospectively maintained institutional database, the details of patients who underwent mastectomy between 2018 and 2022 were obtained. The duration of post-operative stay was obtained and analysed per year to determine the trend. Post-operative surgical complications such as seroma, haematoma, flap necrosis, and surgical site infection were analysed.
    UNASSIGNED: Overall, 147 patients (69%) had early discharge during the review period. Twenty-two patients (10.3%) were discharged within 24 h of surgery, 61 patients (28.6%) were discharged within 24-48 h, and 64 patients (30%) were discharged between 48 and 72 h. There was a steady increase in the adoption of the early discharge protocol over time with a 50% adoption rate in 2018 and 95% in 2022. The mean duration of hospital stay declined steadily from 3.9 days in 2018 to 2.2 days in 2022. Early discharge did not result in any compromise to post-operative outcomes.
    UNASSIGNED: This study demonstrates the sustainability of early post-mastectomy discharge in a resource-limited setting with very satisfactory outcomes. It also provides a unique example of how locally generated evidence can guide local practice. We consider these findings generalisable in other Nigerian hospitals and low- and middle-income countries with similar contexts.

    背景:癌变保乳手术可能使患有早期乳腺癌的女性避免乳房切除术,但是许多女性接受了更广泛的手术,即使提供保乳选项。ANTHEM定性研究的目的是探讨影响女性手术决策的因素,以支持和反对保乳手术。
    方法:对有目的的女性进行了半结构化访谈,这些女性接受了保乳手术或有或没有立即乳房再造的乳房切除术,以探讨其选择手术的理由。访谈被逐字转录并进行主题分析。试验注册号:ISRCTN18238549。
    结果:对来自12个中心的27名妇女进行了访谈。在这些中,12人选择了肿瘤性保乳手术,15人选择了有或没有立即乳房重建的乳房切除术。压倒性的,妇女的决定是由他们的手术团队指导。支持和反对保乳手术的决策受到三个关键相关因素的影响:对肿瘤安全性的看法;保持/恢复女性气质和身体形象的重要性;和实际问题。肿瘤安全是最重要的。报告说感到放心的是,肿瘤学上安全的保乳手术的妇女很乐意选择此选项。那些没有放心的人更有可能选择乳房切除术,作为感知的“更安全”选项。大多数女性希望保持/恢复女性气质,与提供立即乳房重建必不可少的乳房切除术是一个可接受的选择。诸如手术规模之类的实际问题不太重要。
    结论:决策是复杂的,受手术团队的影响很大。高品质,关于手术选择的准确信息,如果女性要做出充分知情的决定,包括适当的保乳手术短期和长期肿瘤安全性的保证至关重要.
    BACKGROUND: Oncoplastic breast-conserving surgery may allow women with early breast cancer to avoid a mastectomy, but many women undergo more extensive surgery, even when breast-conserving options are offered. The aim of the ANTHEM qualitative study was to explore factors influencing women\'s surgical decision-making for and against oncoplastic breast-conserving surgery.
    METHODS: Semi-structured interviews were conducted with a purposive sample of women who had received either oncoplastic breast-conserving surgery or a mastectomy with or without immediate breast reconstruction to explore their rationale for procedure choice. Interviews were transcribed verbatim and analysed thematically. Trial registration number: ISRCTN18238549.
    RESULTS: A total of 27 women from 12 centres were interviewed. Out of these, 12 had chosen oncoplastic breast-conserving surgery and 15 had chosen a mastectomy with or without immediate breast reconstruction. Overwhelmingly, women\'s decisions were guided by their surgical teams. Decision-making for and against oncoplastic breast-conserving surgery was influenced by three key inter-related factors: perceptions of oncological safety; the importance of maintaining/restoring femininity and body image; and practical issues. Oncological safety was paramount. Women who reported feeling reassured that oncoplastic breast-conserving surgery was oncologically safe were happy to choose this option. Those who were not reassured were more likely to opt for a mastectomy, as a perceived \'safer\' option. Most women wished to maintain/restore femininity, with the offer of immediate breast reconstruction essential to make a mastectomy an acceptable option. Practical issues such as the perceived magnitude of the surgery were a lesser concern.
    CONCLUSIONS: Decision-making is complex and heavily influenced by the surgical team. High-quality, accurate information about surgical options, including appropriate reassurance about the short- and long-term oncological safety of oncoplastic breast-conserving surgery is vital if women are to make fully informed decisions.

    巨大纤维腺瘤常见于年轻女性,在围绝经期或更年期女性中很少报道。这些纤维腺瘤被观察为单一的,mobile,从小到大,有明显的界限。这些肿瘤是增生的,其特征是它们在表皮和间充质层中的异常生长。在某些情况下可能伴有疼痛。这些肿瘤与其他上皮和间质肿瘤具有相似的临床相似性,比如叶状肿瘤,除了疾病的严重程度和恶性程度。巨大纤维腺瘤的治疗包括手术切除。手术切除是通过完全切除纤维腺瘤来完成的,保留了其余的乳房组织和乳头乳晕复合体。及时诊断有助于预防不良后果。这是一个40岁的女性,她的右乳房有一个肿块,为此,她接受了广泛的局部切除。在组织病理学上,它被发现是一个巨大的纤维腺瘤。她的术后恢复顺利。
    Giant fibroadenomas are common in young females and are rarely reported in perimenopausal or menopausal females. These fibroadenomas are observed as single, mobile, small to large, with distinct boundaries. These tumors are hyperplastic and characterized by their aberrant growth in both the epidermal and mesenchymal layers, which can be accompanied by pain in some instances. These tumors have similar clinical resemblances to other epithelial and stromal tumors, such as phyllodes tumors, except for the level of disease severity and malignancy. Treatment of giant fibroadenomas includes surgical resection. Surgical excision is done by complete excision of the fibroadenoma, with the rest of the breast tissue and the nipple-areolar complex preserved. Timely diagnosis can be helpful in the prevention of adverse outcomes. This is a case of a 40-year-old female who presented with a lump in her right breast, for which she underwent a wide local excision. On histopathology, it was found to be a giant fibroadenoma. Her postoperative recovery was uneventful.

    目的:乳腺癌治疗的根本性变化促使需要对相关专业人员进行更全面的培训,确保保留肿瘤安全性,同时允许美容干预措施使乳腺癌幸存者受益。这项研究的目的是介绍在培训乳房外科医生中采用的方法,强调了肿瘤成形术和乳房重建的重要性。
    方法:在两个数据库中进行了文献综述,在肿瘤整形外科和乳房重建的背景下,确定与医学教育相关的文章。我们还评估了巴西在肿瘤学中心的经验。
    结果:教育讨论的基础来自16篇文章。我们观察到的方法包括利用模拟器模型的实践课程,猪模型,尸体实验室,和奖学金计划。在巴西观察到积极的结果,这一事实基于七个高级乳腺学家的肿瘤成形术培训中心和五个初级乳腺学家的培训中心。从2009年到2023年,估计有452名老年人和42名大三学生接受了培训,代表巴西约30%的拥有接受过肿瘤成形术培训和经验的乳腺学家。
    结论:尽管关于培训方法的出版物数量有限,巴西的肿瘤学中心取得了重大进展,建立一个可以在其他国家推广的成功模式。
    OBJECTIVE: The radical change in the treatment of breast cancer has promoted the necessity for more comprehensive training of the professionals involved, ensuring the preservation of oncological safety while also allowing for cosmetic interventions to benefit breast cancer survivors. The aim of this study was to present the methods employed in the training of breast surgeons, highlighting the importance of oncoplasty and breast reconstruction.
    METHODS: A literature review was conducted in two databases, identifying articles related to medical education in the context of oncoplastic surgery and breast reconstruction. We also assessed the Brazilian experience in oncoplastic centers.
    RESULTS: The basis for educational discussions was derived from 16 articles. We observed approaches that included hands-on courses utilizing simulator models, porcine models, cadaver labs, and fellowship programs. Positive outcomes were observed in Brazil, a fact based on seven oncoplasty training centers for senior mastologists and five training centers for junior mastologists. From 2009 to 2023, an estimated 452 seniors and 42 juniors received training, representing approximately 30% of mastologists in Brazil who have acquired training and experience in oncoplasty.
    CONCLUSIONS: Despite the limited number of publications on training methods, oncoplastic centers have made significant progress in Brazil, establishing a successful model that can be replicated in other countries.

    目的:评估新辅助内分泌治疗对女性HR阳性/HER2阴性乳腺癌患者的疗效。
    方法:我们确定了年龄≥18岁的cT1-4N0-XM0,HR(),和国家癌症数据库中的HER2(-)乳腺癌。首先接受手术的患者被归类为“首先手术”,而那些在手术前接受NET的人被归类为“NET”。“倾向得分匹配,Cox比例风险模型,方差通货膨胀因素,和交互分析用于估计NET和生存结果之间的相关性。
    结果:在432,387例中,2914例NET患者和2914例首次手术患者进行匹配。与第一组手术相比,NET组接受辅助化疗较少(p<0.001)。此外,与手术组相比,NET组的生存概率更高(3年:91.4%vs.82.1%;5年:82.1%vs.66.8%)。多变量Cox分析表明NET与OS改善相关(手术优先与NET:HR2.17,95%CI:1.93-2.44)。年龄超过55岁,有公共保险,更高的CDCC评分,更高的NSBR等级,ER(+)PR(-),晚期临床分期与OS恶化有关(均p<0.05)。年龄之间有相互作用,种族,收入,以及家庭和治疗方案(均p<0.05)。
    结论:在HR阳性/HER2阴性的女性患者中,NET可能是比手术优先更有效的治疗方法。非转移性乳腺癌患者。未来具有更详细数据的临床研究将提供更高水平的循证数据。
    OBJECTIVE: To assess the efficacy of neoadjuvant endocrine therapy in female HR-positive/HER2-negative breast cancer patients.
    METHODS: We identified female patients aged ≥18 years with cT1-4N0-XM0, HR(+), and HER2(-) breast cancer from the National Cancer Database. The patients who underwent surgery first were categorized as \"surgery-first,\" while those who received NET before surgery were classified as \"NET.\" Propensity score-matching, Cox proportional-hazard model, variance inflation factors, and interaction analysis were employed to estimate the correlation between NET and survival outcomes.
    RESULTS: Among 432,387 cases, 2914 NET patients and 2914 surgery-first patients were matched. Compared with the surgery-first group, the NET group received less adjuvant chemotherapy (p < 0.001). Furthermore, the NET group exhibited higher survival probabilities compared with the surgery-first group (3 years: 91.4% vs. 82.1%; 5 years: 82.1% vs. 66.8%). Multivariate Cox analysis indicated that NET was associated with improved OS (surgery-first vs. NET: HR 2.17, 95% CI: 1.93-2.44). Age over 55 years old, having public insurance, higher CDCC score, higher NSBR grade, ER(+)PR(-), and advanced clinical stage were related to worse OS (all p < 0.05). There was an interaction between age, race, income, and home and treatment regimen (all p < 0.05).
    CONCLUSIONS: NET may be a more effective treatment procedure than surgery-first in female HR-positive/HER2-negative, non-metastatic breast cancer patients. Future clinical studies with more detailed data will provide higher-level evidence-based data.
