Comparing Quality of Life in Breast Cancer Patients Who Underwent Mastectomy Versus Breast-Conserving Surgery: A Meta-Analysis

Body image and psychosocial effects in women after treatment of breast cancer: A prospective study

PURPOSE

To explore treatment-related, socio-economic, and psychological factors influencing body image and return to work.

MATERIALS AND METHODS

137 patients participated in the study. A questionnaire was completed before surgery and at 1-year follow-up, where patients were also interviewed in person with questions modified from the Body Image Scale and the sexual adjustment scale as well as questions about their work status.

RESULTS

There was a significant decline in body image score from baseline to 1-year follow-up related to younger age, more extensive surgery and post-surgery treatments. Treatment with adjuvant chemotherapy was associated with a lower rating on ability to work in relation to mental requirements and later return to work. Higher anxiety scores at baseline were associated with both a decline in body image and a delay in return to work.

CONCLUSION

Breast cancer surgery can affect body image and especially adjuvant chemotherapy seems to affect work ability. However, personal characteristics are also involved and thus should be considered when planning for treatment of breast cancer.

Breast Conservation Project: Clinical Outcomes of Extreme Oncoplastic Breast-Conserving Therapy Versus Mastectomy for Large and Multiple Lesions

INTRODUCTION

Patients with multiple or large malignant breast lesions are classically considered mastectomy candidates, but extreme oncoplastic breast-conservation surgery (eOBCS) has become an alternative approach. There is a paucity of outcomes data comparing eOBCS with mastectomy.

METHODS

We reviewed our prospectively maintained, single-institution database. We included patients with non-metastatic breast cancer with multiple ipsilateral or single large (≥ 5 cm) malignant breast lesions identified preoperatively who underwent either eOBCS or mastectomy. Patient demographics, clinicopathologic features, and surgical, oncologic, and cosmetic outcomes were evaluated.

RESULTS

Seventy-six (88%) patients underwent eOBCS and 10 (12%) underwent mastectomy. Median follow-up was 24.8 months. Mastectomy patients had larger lesions than eOBCS patients (median 70 mm vs. 32.5 mm; p = 0.06). Six (60%) index mastectomy patients underwent at least one additional surgery. For eOBCS patients, 34 (44%) required re-excision, 7 of whom underwent more than one subsequent surgery to obtain negative margins, and 6 (7.9%) ultimately underwent mastectomy. For patients undergoing additional surgery (n = 40), median time between index and final operation was 315 days for mastectomy versus 21 days for eOBCS patients (p < 0.001). Mastectomy patients more frequently experienced complications (p = 0.001) and underwent cosmetic revision (p < 0.001). There was no difference in cosmetic scores, and eOBCS patients reported less pain (p = 0.009). There were two local and three distant recurrences in the eOBCS cohort and one distant recurrence in the mastectomy group.

CONCLUSION

Breast conservation was attainable in over 90% of eOBCS patients. Increased postoperative complications and discomfort and longer duration of surgical treatment in mastectomy patients without oncologic superiority should drive informed patient discussions.

Extreme Oncoplasty: Oncologically Safe When Compared with Mastectomy

BACKGROUND

Extreme oncoplasty is a breast-conserving operation using oncoplastic techniques in a patient who does not meet the traditional criteria for breast conservation and in whom most physicians would suggest a mastectomy. These tumors are generally multicentric and/or multifocal, they span more than 50 mm, or they can be large recurrences in a previously irradiated breast.

METHODS

A prospective single institution database was queried from 2008 through mid 2023 for patients who met the criteria for extreme oncoplasty and were treated with excision plus whole-breast radiation therapy (WBRT) or mastectomy without WBRT. Patients with recurrent breast cancer were excluded. Endpoints were local, regional, and distant recurrence as well as overall and breast-cancer-specific survival.

RESULTS

272 patients were treated with oncoplastic mammaplasty, using a standard or split reduction excision followed by postoperative WBRT. An additional 101 patients elected to be treated with mastectomy without postoperative radiation therapy. With a median follow-up of 7 years, there were no significant differences in local, regional, or distant recurrence, nor in breast-cancer-specific survival or overall survival.

CONCLUSIONS

We strongly support extreme oncoplasty plus WBRT as the default procedure of choice for patients with large multifocal/multicentric lesions amenable to reconstruction with volume displacement mammaplasty.

Predictors of Lumpectomy Size after Breast-Conserving Surgery in Patients with Breast Cancer: A Retrospective Cohort Study

BACKGROUND

Oncoplastic reconstructive surgery as an extension of breast-conserving surgery leads to better aesthetic results, an increase in tumor-free margins, and a reduction in reexcision rates. Oncologic resection is often more extensive than expected, sometimes resulting in the plastic surgeon deviating from the predetermined plan. For optimal planning of the reconstruction, it is mandatory to estimate volume defects after lumpectomy as accurately as possible. The authors aimed to identify preoperative predictors of lumpectomy resection size.

METHODS

All consecutive patients diagnosed with invasive breast carcinoma or carcinoma in situ and treated primarily with breast-conserving surgery between 2018 and 2020 at the University Medical Center Utrecht or Alexander Monro Hospital were included. Patient and tumor characteristics were measured. Data were analyzed in a multiple linear regression analysis.

RESULTS

A total of 410 patients (423 cases) were included, with a median age of 58 years (range, 32 to 84 years) and a mean body mass index (BMI) of 25.0 (SD 9.3). The mean maximum radiologic tumor diameter was 18.0 mm (SD 13.2), and the mean maximum lumpectomy diameter was 58.8 mm (SD 19.2). Multiple linear regression analysis found an explained variance of R 2 = 0.60 ( P < 0.00), corrected for operating surgeon. Significant predictors for postoperative lumpectomy size were BMI, breast size, and maximum preoperative radiologic tumor diameter. A predictive tool for lumpectomy size was developed and a web-based application created to facilitate use of the tool in a clinical setting.

CONCLUSIONS

Postoperative lumpectomy size can be predicted using BMI, breast size, and radiologic tumor size. This model could be beneficial for breast surgeons in planning reconstructions and preparing and informing their patients more accurately.

Bibliometric analysis of quality of life in implant-based breast reconstruction

Background

Implant-based breast reconstruction (IBR), following mastectomy, significantly impacts patients' quality of life (QoL), necessitating accurate measurement through psychometrically robust patient-reported outcome measure (PROM) tools. This bibliometric analysis aims to discern trends, identify gaps, and evaluate the use of such tools in the IBR literature.

Methods

The 100 most cited publications regarding QoL in implant-based reconstruction were identified on Web of Science, across all available journal years (from 1977 to 2024) on 10 March 2024. Study details, including the citation count, main content focus, outcome measures, and usage of psychological questionnaires, were extracted and tabulated from each publication. The Oxford Centre for Evidence-Based Medicine (OCEBM) levels of evidence (LOE) of each study were assessed.

Results

The 100 most cited publications on QoL in implant-based reconstruction were identified, encompassing 64,192 patients and 28,114 reconstructed breasts. Citations per publication ranged from 62 to 457 (mean, 124.95 ± 73.05), with the highest-cited study being authored by Al-Ghazal (n = 457). The vast majority of publications were LOE II (n = 52), representative of prospective cohort studies, systematic reviews of non-randomised studies, and systematic review and meta-analysis. The number of publications for LOE V, IV, III, and I was 0, 7, 41, and 0, respectively. The main content focus was "quality of life" in 83 publications, with significant utilisation of the BREAST-Q questionnaire. A total of 80 publications used validated questionnaires with psychometric development.

Conclusions

This analysis demonstrates that the research methodologies within IBR mostly consist of moderate-quality publications; however, notably, there was a lack of LOE I studies, underscoring a gap in high-quality research within the field. Moreover, only 62/100 used validated PROM tools. Future IBR research studies should be focussed on most robust methodologies, incorporating validated PROM tools, to optimise shared-decision making and informed consent.

A bibliometric worldview of breast-conserving surgery for breast cancer from 2013 to 2023

Over the last decade, significant advancements have been made in breast-conserving surgery (BCS) for breast cancer. However, there is a lack of analytical and descriptive investigations on the trajectory, essential research directions, current research scenario, pivotal investigative focuses, and forthcoming perspectives. The objective of this research is to provide a thorough update on the progress made in BCS for breast cancer over the preceding decade. Retrieved from the Web of Science database, the data span from January 1, 2013, to November 30, 2023. Utilizing a set of advanced analytical instruments, we conducted comprehensive bibliometric and visual analyses. The findings underscore the predominant influence of the USA, representing 35.77% of the overall publications and playing a pivotal role in shaping research within this field. Notable productivity was evident at various institutions, including the Memorial Sloan Kettering Cancer Center, the University of Texas MD Anderson Cancer Center, and the University of Toronto. Annals of Surgical Oncology contributed the most publications in this field. An examination of keywords indicated a change in the concentration of research attention, transitioning from molecular subtype, ultrasonography, and intraoperative aspects to SEER, male breast cancer, and adjuvant measures. By offering a comprehensive bibliometric assessment, this study enhances our understanding of BCS for breast cancer. Consequently, this benefits both experienced researchers and newcomers alike, providing prompt access to essential information and fostering the extraction of innovative concepts within this specific field.

A meta-analysis of randomized controlled trials comparing breast-conserving surgery and mastectomy in terms of patient survival rate and quality of life in breast cancer

The study aimed to assess the effects of breast-conserving surgery (BCS) versus mastectomy on survival and quality of life in Stages I, II, and III breast cancer, providing solid evidence for clinical decisions. We conducted a meta-analysis of randomized controlled trials on breast cancer treatments, searching databases such as PubMed and the Cochrane Library to compare BCS, and mastectomy's effects on survival and quality of life. A combined total of 16 734 patients in the control group and 17 435 patients in the experimental group were included in this analysis. This meta-analysis used RevMan 5.3 (Cochrane Collaboration, Copenhagen, Denmark) software for analysis. Our meta-analysis of 34 169 patients from 11 studies showed that BCS significantly reduced the overall recurrence rate at a median follow-up of 29 months, with a mean difference of 1.27 and a 95% confidence interval of 1.19-1.36, strongly supporting its effectiveness (P < .00001). Furthermore, our analysis found no significant increase in 5-year local recurrence rates for BCS versus mastectomy, indicating its long-term effectiveness with a mean difference of 1.13 (95% confidence interval: [1.03, 1.24], P = .01). Additionally, there was a notable decrease in tissue ischaemic necrosis among patients who had received BCS, with a mean difference of 0.37 (95% confidence interval: [0.33, 0.42], P < .00001), underscoring its benefits and long-term viability. BCS resulted in fewer cases of tissue ischaemic necrosis and higher body image scores compared with mastectomy, suggesting that it is a preferable option for better cosmetic outcomes and potentially favourable effects on prognosis and quality of life.

Quality of Life after Mastectomy with or without Breast Reconstruction and Breast-Conserving Surgery in Breast Cancer Survivors: A Cross-Sectional Study at a Tertiary Hospital in Ghana

(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.

Differentiating Primary and Recurrent Lesions in Patients with a History of Breast Cancer: A Comprehensive Review

Breast cancer (BC) recurrence remains a concerning issue, requiring accurate identification and differentiation from primary lesions for optimal patient management. This comprehensive review aims to summarize and evaluate the current evidence on methods to distinguish primary breast tumors from recurrent lesions in patients with a history of BC. Also, we provide a comprehensive understanding of the different imaging techniques, including mammography, ultrasound, magnetic resonance imaging, and positron emission tomography, highlighting their diagnostic accuracy, limitations, and potential integration. In addition, the role of various biopsy modalities and molecular markers was explored. Furthermore, the potential role of liquid biopsy, circulating tumor cells, and circulating tumor DNA in differentiating between primary and recurrent BC was emphasized. Finally, it addresses emerging diagnostic modalities, such as radiomic analysis and artificial intelligence, which show promising potential in enhancing diagnostic accuracy. Through comprehensive analysis and review of the available literature, the current study provides an up-to-date understanding of the current state of knowledge, challenges, and future directions in accurately distinguishing between primary and recurrent breast lesions in patients with a history of BC.

Cost-effectiveness of intraoperative radiation therapy versus intensity-modulated radiation therapy for the treatment of early breast cancer: a disinvestment analysis

BACKGROUND

Adjuvant radiotherapy represents a key component in curative-intent treatment for early-stage breast cancer patients. In recent years, two accelerated partial breast irradiation (APBI) techniques are preferred for this population in our organization: electron-based Intraoperative radiation therapy (IORT) and Linac-based External Beam Radiotherapy, particularly Intensity-modulated radiation therapy (IMRT). Recently published long-term follow-up data evaluating these technologies have motivated a health technology reassessment of IORT compared to IMRT.

METHODS

We developed a Markov model to simulate health-state transitions from a cohort of women with early-stage breast cancer, after lumpectomy and adjuvant APBI using either IORT or IMRT techniques. The cost-effectiveness from a private health provider perspective was assessed from a disinvestment point of view, using life-years (LYs) and recurrence-free life-years (RFLYs) as measure of benefits, along with their respective quality adjustments. Expected costs and benefits, and the incremental cost-effectiveness ratio (ICER) were reported. Finally, a sensitivity and scenario analyses were performed to evaluate the cost-effectiveness using lower IORT local recurrence and metastasis rates in IORT patients, and if equipment maintenance costs are removed.

RESULTS

IORT technology was dominated by IMRT in all cases (i.e., fewer benefits with greater costs). Despite small differences were found regarding benefits, especially for LYs, costs were considerably higher for IORT. For sensitivity analyses with lower recurrence and metastasis rates for IORT, and scenario analyses without equipment maintenance costs, IORT was still dominated by IMRT.

CONCLUSIONS

For this cohort of patients, IMRT was, at least, non-inferior to IORT in terms of expected benefits, with considerably lower costs. As a result, IORT disinvestment should be considered, favoring the use of IMRT in these patients.

Breast-conserving surgery is associated with a lower incidence of suicide among females with breast cancer in the United States: a population-based retrospective cohort study

BACKGROUND

With comparable overall survival and local recurrence rates with mastectomy, breast-conserving surgery (BCS) has become the cornerstone of therapy for breast cancer; however, the difference in the incidence of suicide between BCS and mastectomy among breast cancer survivors remains unclear. This study evaluated the mortality risk from suicide among breast cancer survivors and compared suicide risk between BCS and mastectomy using a population-based cohort.

MATERIALS AND METHODS

Female patients newly diagnosed with first primary breast cancer, recorded in the Surveillance, Epidemiology and End Results database, were included. Standardized mortality ratio (SMR) and cumulative mortality rate from suicide among those who underwent BCS and mastectomy were compared.

RESULTS

A total of 1 190 991 patients with newly diagnosed first primary breast cancer were included in the study, of whom 56.5% underwent BCS and 36.1% underwent mastectomy. During the follow-up period, 667 suicides were recorded. Patients who underwent mastectomy exhibited significantly higher suicide mortality than the general population [mortality rate, 8.16 per 100 000 person-years; SMR 1.18 (95% CI 1.05-1.33)], while there was no significant difference in suicide rate between patients who underwent BCS and the general population [SMR 0.92 (95% CI 0.83-1.02)]. Multivariate Cox analysis revealed that BCS, compared with mastectomy, was associated with a significantly decreased risk of suicide among females with breast cancer [hazard ratio 0.80 (95% CI 0.68-0.95); P = 0.009].

CONCLUSION

BCS was associated with a significantly lower incidence of suicide among females with breast cancer. BCS offers a compelling option for improving the quality of life and self-esteem of patients with cancer and provides a novel perspective on cancer management.

Outcomes and complications of intraoperative radiotherapy versus external beam radiotherapy for early breast cancer

BACKGROUND

Intraoperative radiotherapy (IORT) is an alternative for external beam radiotherapy (EBRT) for early stage breast cancer (BC). Herein, we compared outcomes, postoperative and post-radiation complications of IORT and EBRT.

METHODS

We conducted a cohort study to compare complications of IORT and EBRT in patients. A checklist of the complications of IORT and EBRT, was used to assess and post-radiation complications and outcomes.

RESULTS

Overall, 264 women (121 in IORT and 143 in EBRT group) with a mean (SD) age of 55 ± 8.6 years analyzed in this study. The IORT group (quadrantectomy + SLNB + IORT) had more severe post-operative pain compared to the EBRT group (quadrantectomy + SLNB) (OR = 1.929, 95% CI: 1.116-3.332). Other postoperative complications, including edema, erythema, seroma, hematoma, and wound complications were not significantly different between the IORT and EBRT groups. EBRT was associated with higher rates post-radiation complications, including erythema (95.8% vs. 21.5%), skin dryness (30.8% vs. 12.4%), pruritus (26.6% vs. 17.4%), hyperpigmentation (48.3% vs. 9.9%), and telangiectasia (1.4% vs. 0.8%). Multivariate analysis showed that erythema, skin dryness and pruritus, and hyperpigmentation were more severe in the EBRT group, while breast induration was higher in the IORT group (OR = 4.109, 95% CI: 2.242-7.531). Excellent, good, and fair cosmetic outcome was seen in 11.2%, 72%, and 16.8% of the patients in the EBRT group and 29.8%, 63.6%, and 6.6% in the IORT group, respectively, suggesting that the cosmetic outcome was significantly better in the IORT group (P < .001). There wasn't statistically significant difference in recurrence-free survival and overall survival rates between two groups of patients who received either IORT or EBRT (P = .953, P = .56).

CONCLUSION

IORT is considered to have lower post-radiation complications and better cosmetic outcomes in breast cancer patients. Therefore, IORT might be used as the treatment of choice in eligible patients.

European quality indicators developed by the European Commission Initiative on Breast Cancer: a first nationwide assessment for the Dutch setting

PURPOSE

This observational study aims to assess the feasibility of calculating indicators developed by the European Commission Initiative on Breast Cancer (ECIBC) for the Dutch breast cancer population.

METHODS

Patients diagnosed with invasive or in situ breast cancer between 2012 and 2018 were selected from the Netherlands Cancer Registry (NCR). Outcomes of the quality indicators (QI) were presented as mean scores and were compared to a stated norm. Variation between hospitals was assessed by standard deviations and funnel plots and trends over time were evaluated. The quality indicator calculator (QIC) was validated by comparing these outcomes with the outcomes of constructed algorithms in Stata.

RESULTS

In total, 133,527 patients were included. Data for 24 out of 26 QIs were available in the NCR. For 67% and 67% of the QIs, a mean score above the norm and low or medium hospital variation was observed, respectively. The proportion of patients undergoing a breast reconstruction or neoadjuvant systemic therapy increased over time. The proportion treated within 4 weeks from diagnosis, having >10 lymph nodes removed or estrogen negative breast cancer who underwent adjuvant chemotherapy decreased. The outcomes of the constructed algorithms in this study and the QIC showed 100% similarity.

CONCLUSION

Data from the NCR could be used for the calculation of more than 92% of the ECIBC indicators. The quality of breast cancer care in the Netherlands is high, as more than half of the QIs already score above the norm and medium hospital variation was observed. The QIC can be easy and reliably applied.

The Role of Human Epidermal Growth Factor Receptor 2 (HER2)-Targeted Therapies in Early-Stage Breast Cancer: Current Practices, Treatment De-escalation, and Future Prospects

Human epidermal growth factor receptor 2 (HER2)-targeted therapy has transformed the treatment paradigm for early-stage HER2-positive breast cancer, providing personalized and effective interventions. This comprehensive review delves into the current state of HER2-targeted therapies, emphasizing pivotal clinical trials that have demonstrated their substantial impact on long-term outcomes. Combination therapies that integrate HER2-targeted agents with chemotherapy exhibit enhanced tumor responses, particularly in neoadjuvant settings. Neoadjuvant chemotherapy (NACT) is explored for its role in tumor downsizing, facilitating breast-conserving surgery (BCS), and incorporating oncoplastic solutions to address both oncologic efficacy and aesthetic outcomes. Innovative axillary management post-NACT, such as targeted axillary dissection (TAD), is discussed for minimizing morbidity. The review further explores the delicate balance between maximal therapy and de-escalation, reflecting recent trends in treatment approaches. The therapeutic landscape of HER2-low breast cancer is examined, highlighting considerations in HER2-positive breast cancer with BReast CAncer gene (BRCA) mutations. Emerging immunotherapeutic strategies, encompassing immune checkpoint inhibitors and chimeric antigen receptor (CAR) T-cell therapy, are discussed in the context of their potential integration into treatment paradigms. In conclusion, the evolving landscape of HER2-positive early-stage breast cancer treatment, characterized by targeted therapies and multidisciplinary approaches, underscores the need for ongoing research and collaborative efforts. The aim is to refine treatment strategies and enhance patient outcomes in this dynamic and rapidly evolving field.

Comparison of adverse events in partial- or whole breast radiotherapy: investigation of cosmesis, toxicities and quality of life in a meta-analysis of randomized trials

PURPOSE/OBJECTIVE

Adjuvant whole breast radiotherapy and systemic therapy are part of the current evidence-based treatment protocols for early breast cancer, after breast-conserving surgery. Numerous randomized trials have investigated the therapeutic effects of partial breast irradiation (PBI) compared to whole breast irradiation (WBI), limiting the treated breast tissue. These trials were designed to achieve equal control of the disease with possible reduction in adverse events, improvements in cosmesis and quality of life (QoL). In this meta-analysis, we aimed to investigate the differences between PBI and WBI in side effects and QoL.

MATERIAL/METHODS

We performed a systematic literature review searching for randomized trials comparing WBI and PBI in early-stage breast cancer with publication dates after 2009. The meta-analysis was performed using the published event rates and the effect-sizes for available acute and late adverse events. Additionally, we evaluated cosmetic outcomes as well as general and breast-specific QoL using the EORTC QLQ-C30 and QLQ-BR23 questionnaires.

RESULTS

Sixteen studies were identified (n = 19,085 patients). PBI was associated with a lower prevalence in any grade 1 + acute toxicity and grade 2 + skin toxicity (OR = 0.12; 95% CI 0.09-0.18; p < 0.001); (OR = 0.16; 95% CI 0.07-0.41; p < 0.001). There was neither a significant difference in late adverse events between the two treatments, nor in any unfavorable cosmetic outcomes, rated by either medical professionals or patients. PBI-technique using EBRT with twice-daily fractionation schedules resulted in worse cosmesis rated by patients (n = 3215; OR = 2.08; 95% CI 1.22-3.54; p = 0.007) compared to WBI. Maximum once-daily EBRT schedules (n = 2071; OR = 0.60; 95% CI 0.45-0.79; p < 0.001) and IORT (p = 0.042) resulted in better cosmetic results grade by medical professionals. Functional- and symptom-based QoL in the C30-scale was not different between PBI and WBI. Breast-specific QoL was superior after PBI in the subdomains of "systemic therapy side effects" as well as "breast-" and "arm symptoms".

CONCLUSION

The analysis of multiple randomized trials demonstrate a superiority of PBI in acute toxicity as well breast-specific quality of life, when compared with WBI. Overall, late toxicities and cosmetic results were similar. PBI-technique with a fractionation of twice-daily schedules resulted in worse cosmesis rated by patients.

Evaluation of quality of life in breast cancer patients who underwent breast-conserving surgery or mastectomy using real-world data

BACKGROUND

Due to advances in the fight against breast cancer, aesthetic aspects and the prevention of breast deformities are playing an important role in surgical procedures. Currently the main form of breast cancer surgery is breast-conserving surgery (BCS), and even if mastectomy (MAS) is required, oncoplastic surgery and reconstruction options can improve outcomes, including health-related quality of life (QoL) of cancer patients. The purpose of this study was to assess whether surgery options induce different outcomes in self-reported QoL in guide-line treated breast cancer patients of the Network Oncology (NO).

METHODS

This prospective Real-World-Data (RWD) study was conducted using data from the NO-clinical registry. QoL was assessed by evaluation of the European Organization of Research and Treatment Health-Related Quality of Life Core Questionnaire scale (EORTC QLQ-C30). Association factors between type of surgery options, without or with immediate breast reconstructions the EORTC QLQ-C30-scales at baseline after surgery, 6, 12, and 24 months later were analyzed with adjusted multivariate regression analysis, considering age, cancer stage, and treatment regimens, using software R.

RESULTS

A total of 623 primary breast cancer patients (all tumor stages, median age 58 (ICR: 50-68) diagnosed and guide-line treated between 2013 and 2021), 524 BCS and 99 MAS, 24 of whom received immediate breast reconstruction (MBR), were eligible for analyses. Compared with BCS patients, MBR patients self-reported considerably lower global health, physical and social functioning, and higher burden of pain and financial difficulties at baseline. In later follow-up surveys, functional scales increased and symptoms decreased in all patients, and the differences between MAS and BCS equalized. Longitudinal analyses after 24 months were obtained from 258 patients and revealed that compared to 224 BCS, the 34 MAS patients reported increased social functioning (p = 0.04).

CONCLUSIONS

At 24 months after MAS, breast cancer patients' QoL improved compared with BCS, although impairments in QoL were reported immediately after MAS. A growing expertise in surgical procedures as well as supportive care is critical to optimizing patients' well-being. These findings may be considered when counseling breast cancer patients pre- and post-surgery.

How Can Oncoplastic Breast Surgery Contribute to the Management of Locally Advanced Breast Cancer in Sub-Saharan Africa?

Background

Because of resource constrains in sub-Saharan African countries, breast-conserving surgery (BCS) has no role in patients with locally advanced breast cancer (LABC) following neoadjuvant chemotherapy (NACT), and mastectomy remains the standard surgical treatment for these patients.

Objectives

The first objective of the study was to assess the safety of oncoplastic BCS in patients with LABC who showed good clinical response to NACT in a breast center with enhanced level of resources in Sudan. The second objective was to assess the cosmetic outcome.

Patients and Methods

Two hundred and fifty patients with LABC were treated with NACT at Khartoum Breast Care Center during the period 2013-2019. Out of this, 52 patients were surgically treated with oncoplastic breast-conserving surgery. Kaplan-Meier curve was used to calculate the survival rates. The cosmetic outcome was subjectively assessed by the Harris scale.

Results

The median follow-up period was 53 months. The 3- and 5-years distant metastasis-free survival rates were 92.9% and 82.2%, respectively. One patient developed regional recurrence, and 6 patients developed distant metastasis. Eighty percentage of patients were admitted to have good to excellent cosmetic outcome.

Conclusion

This Sudanese experience showed that oncoplastic BCS is oncologically safe and aesthetically satisfactory in patients with LABC who demonstrated good clinical response to NACT in a setting with enhanced levels of resources for breast cancer care.

Feasibility of In Vivo Metal Artifact Reduction in Contrast-Enhanced Dedicated Spiral Breast Computed Tomography

BACKGROUND

Radiopaque breast markers cause artifacts in dedicated spiral breast-computed tomography (SBCT). This study investigates the extent of artifacts in different marker types and the feasibility of reducing artifacts through a metal artifact reduction (MAR) algorithm.

METHODS

The pilot study included 18 women who underwent contrast-enhanced SBCT. In total, 20 markers of 4 different types were analyzed for artifacts. The extent of artifacts with and without MAR was measured via the consensus of two readers. Image noise was quantitatively evaluated, and the effect of MAR on the detectability of breast lesions was evaluated on a 3-point Likert scale.

RESULTS

Breast markers caused significant artifacts that impaired image quality and the detectability of lesions. MAR decreased artifact size in all analyzed cases, even in cases with multiple markers in a single slice. The median length of in-plain artifacts significantly decreased from 31 mm (range 11-51 mm) in uncorrected to 2 mm (range 1-5 mm) in corrected images (p ≤ 0.05). Artifact size was dependent on marker size. Image noise in slices affected by artifacts was significantly lower in corrected (13.6 ± 2.2 HU) than in uncorrected images (19.2 ± 6.8 HU, p ≤ 0.05). MAR improved the detectability of lesions affected by artifacts in 5 out of 11 cases.

CONCLUSION

MAR is feasible in SBCT and improves the image quality and detectability of lesions.

Quality of life and cost-effectiveness of different breast cancer surgery procedures: a Markov decision tree-based approach in the framework of Predictive, Preventive, and Personalized Medicine

Purpose

Breast cancer is a complex disease with heterogeneous outcomes that may benefit from the implementation of Predictive, Preventive, and Personalized Medicine (PPPM/3PM) strategies. In this study, we aimed to explore the potential of PPPM approaches by investigating the 10-year trends in quality of life (QOL) and the cost-effectiveness of different types of surgeries for patients with breast cancer.

Methods

This prospective cohort study recruited 144 patients undergoing breast conserving surgery (BCS), 199 undergoing modified radical mastectomy (MRM), and 44 undergoing total mastectomy with transverse rectus abdominis myocutaneous flap (TRAMF) from three medical centers in Taiwan between June 2007 and June 2010.

Results

All patients exhibited a significant decrease in most QOL dimension scores from before surgery to 6 months postoperatively (p < 0.05); however, from postoperative year 1 to 2, improvement in most QOL dimension scores was significantly better in the TRAMF group than in the BCS and MRM groups (p < 0.05). At 2, 5, and 10 years after surgery, the patients' QOL remained stable. In the Markov decision tree model, the TRAMF group had higher total direct medical costs than the MRM and BCS groups (US$ 32,426, US$ 29,487, and US$ 28,561, respectively) and higher average QALYs gained (7.771, 6.773, and 7.385, respectively), with an incremental cost-utility ratio (ICUR) of US$ 2,944.39 and US$ 10,013.86 per QALY gained.

Conclusions

TRAMF appeared cost effective compared with BCS and MRM, and it has been proved with considerable QOL improvements in the framework of PPPM. Future studies should continue to explore the potential of PPPM approaches in breast cancer care. By incorporating predictive models, personalized treatment plans, and preventive strategies into routine clinical practice, we can further optimize patient outcomes and reduce healthcare costs associated with breast cancer treatment.

A Dutch randomized controlled study shows autologous fat transfer with pre-expansion is more cost-effective in the long term than implants

BACKGROUND

One in seven women will develop breast cancer, making it the most common female cancer worldwide. Consequently, breast cancer-related treatment, including breast reconstruction, impacts societal costs. Autologous fat transfer (AFT) is a relatively new breast reconstruction technique; however, several surgeries are necessary. This study investigates if AFT with pre-expansion is more cost-effective than implant-based reconstruction (IBR).

METHODS

Seven centers assigned patients randomly from 2015 to 2021 to evaluate costs and EQ-5D-5L quality-adjusted life years (QALY) of AFT vs. IBR at 12 months postoperative. Costs were calculated, including direct costs related to treatment and PROductivity and DISease Questionnaire, to estimate productivity loss (indirect costs). Sensitivity analyses were performed for 10- and 30 years to estimate costs for patients replacing or explanting their breast implants over time.

RESULTS

A total of 152 women, of which 91 received AFT (mean age 49.3) and 80 IBR (mean age 49.1). The mean EQ-5D-5L QALY in the AFT group was 0.83, compared with the IBR group of 0.79. Total costs for AFT at 12 months postoperative were higher than IBR (incremental cost: €6763.59). Sensitivity analyses for 10- and 30-year scenarios showed mean incremental costs of respectively €2586.56 and €680.22.

CONCLUSION

Mean EQ-5D-5L QALY and costs were higher for AFT over the first year after reconstruction. However, these costs were low; therefore, AFT was estimated to be more cost-effective over the 10- and 30-year period since no additional surgeries are necessary for this group. Larger cohorts are required to confirm AFT is more cost-effective in the long term.

Secretome profiling of Artemisia absinthium extract-loaded polymeric nanoparticle-treated MCF-7 and MDA-MB-231 revealed perturbation in microtubule assembly and cell migration

Introduction

Artemisia absinthium (wormwood) exhibits anticancer properties by inhibiting proliferation and causing cell death in breast cancer. Targeted drug delivery of A. absinthium nanoformulation using N-isopropyl acrylamide, N-vinyl pyrrolidone, and acrylic acid-based polymeric nanoparticles (NVA-AA NPs) was ensured by utilizing features of the tumor microenvironment, although their mechanism of action involved in cytotoxicity remains unknown.

Methods

The present study employed nano LC-MS/MS to identify differences in secretory protein expression associated with the treatment of breast cancer cell lines (MCF-7; MDA-MB-231) by NVA-AA NPs for the determination of affected pathways and easily accessible therapeutic targets. Different bioinformatics tools were used to identify signature differentially expressed proteins (DEPs) using survival analysis by GENT2 and correlation analysis between their mRNA expressions and sensitivity toward small-molecule drugs as well as immune cell infiltration by GSCA.

Results

Analysis by GENT2 revealed 22 signature DEPs with the most significant change in their expression regulation, namely, gelsolin, alpha-fetoprotein, complement component C3, C7, histone H2B type 1-K, histone H2A.Z, H2AX, heat shock cognate 71 kDa protein, heat shock 70 kDa protein 1-like, cytochrome c somatic, GTP-binding nuclear protein Ran, tubulin beta chain, tubulin alpha-1B chain, tubulin alpha-1C chain, phosphoglycerate mutase 1, kininogen 1, carboxypeptidase N catalytic chain, fibulin-1, peroxiredoxins 4, lactate dehydrogenase C, SPARC, and SPARC-like protein 1. Correlation analysis between their mRNA expressions versus immune cell infiltrates showed a positive correlation with antitumor immune response elicited by these NPs as well as a correlation with drug response shown by the GDSC and CTRP drugs in different cancer cells.

Discussion

Our results suggest that NVA-AA NPs were able to invade the tumor microenvironment; transformed the communication network between the cancer cells; affected potential drivers of microtubular integrity, nucleosome assembly, and cell cycle; and eventually caused cell death.

Radiotherapy Use and Incidence of Locoregional Recurrence in Patients With Favorable-Risk, Node-Positive Breast Cancer Enrolled in the SWOG S1007 Trial

Importance

Little is known about regional nodal irradiation (RNI) practice patterns or rates of locoregional recurrence (LRR) with and without RNI in patients with limited nodal disease and favorable biology treated with modern surgical and systemic therapy, including approaches that de-escalate those latter treatments.

Objective

To investigate how often patients with low-recurrence score breast cancer with 1 to 3 nodes involved receive RNI, incidence and predictors of LRR, and associations between locoregional therapy and disease-free survival.

Design, Setting, and Participants

In this secondary analysis of the SWOG S1007 trial, patients with hormone receptor-positive, ERBB2-negative breast cancer, and a Oncotype DX 21-gene Breast Recurrence Score assay result of no more than 25, were randomized to endocrine therapy alone vs chemotherapy then endocrine therapy. Prospectively collected radiotherapy information was collected from 4871 patients treated in diverse settings. Data were analyzed June 2022 to April 2023.

Exposure

Receipt of RNI (targeting at least the supraclavicular region).

Main Outcome(s) and Measure(s)

Cumulative incidence of LRR was calculated by locoregional treatment received. Analyses were assessed for associations between invasive disease-free survival (IDFS) and locoregional therapy, adjusted for menopausal status, treatment group, recurrence score, tumor size, nodes involved, and axillary surgery. Radiotherapy information was recorded in the first year after randomization, so survival analyses were landmarked as starting at 1 year among those still at risk.

Results

Of 4871 female patients (median [range] age, 57 [18-87] years) with radiotherapy forms, 3947 (81.0%) reported radiotherapy receipt. Of 3852 patients who received radiotherapy and had complete information on targets, 2274 (59.0%) received RNI. With a median follow-up of 6.1 years, the cumulative incidence of LRR by 5 years was 0.85% among patients who received breast-conserving surgery and radiotherapy with RNI; 0.55% after breast-conserving surgery with radiotherapy without RNI; 0.11% after mastectomy with postmastectomy radiotherapy; and 1.7% after mastectomy without radiotherapy. Similarly low LRR was observed within the group assigned to endocrine therapy without chemotherapy. The rate of IDFS did not differ by RNI receipt (premenopausal: hazard ratio [HR], 1.03; 95% CI, 0.74-1.43; P = .87; postmenopausal: HR, 0.85; 95% CI, 0.68-1.07; P = .16).

Conclusions and Relevance

In this secondary analysis of a clinical trial, RNI use was divided in the setting of biologically favorable N1 disease, and rates of LRR were low even in patients who did not receive RNI. Disease-free survival was not associated with RNI receipt; omission of chemotherapy among patients similar to those enrolled in the S1007 trial is not an independent indication for use of RNI.

How well are Brazilian mastologists (breast surgeons) trained in breast reconstruction and oncoplastic surgery? A study of the impact of a breast reconstruction and oncoplastic surgery improvement course

Introduction

The breasts are a female symbol, impacts self-image and self-esteem. Breast reconstructive and oncoplastic surgeries have an important role in minimizing injuries. In Brazil less than a third of public health system (SUS) users have access to immediate reconstructive surgery. The low rate of breast reconstructions has multiple causes and the deficiency in availability and surgeons' technical qualification play a role. In 2010, the Breast Reconstruction and Oncoplastic Surgery Improvement Course was created by professors of the Mastology Department of Santa Casa de São Paulo and State University of Campinas (UNICAMP). The objectives of this study were to evaluate the impact of the techniques learned on patients' management by the surgeons enrolled in the Course, as well as to characterize their profile.

Methods

All students enrolled in the Improvement Course between 2010 and 2018 were invited to answer an online questionnaire. Students who did not agree to answer the questionnaire or answered them incompletely were excluded.

Results

Total students included: 59. The mean age: 48.9 years, male (72%) with more than 5 years of Mastology practice (82.2%), from all regions of Brazil, 1.7% from the North, 33.9% from the Northeast, 44.1% from the Southeast, and 12% from the South. Most of the students considered they had little or no knowledge of breast reconstruction (74.6%) and 91,5% did not consider they had enough aptitude to perform breast reconstructions after finishing residency. After the Course, 96.6% considered themselves apt to perform such surgeries. Over 90% of the students considered the Course had impacted their practice and changed their surgical strategy view. Before the Course, 84.8% of the students stated that less than half of their patients who were operated on for breast cancer had breast reconstruction, compared to 30.5% after the Course.

Conclusion

The Breast Reconstruction and Oncoplastic Surgery Improvement Course studied here positively impacted the mastologists' management of patients. New training centers worldwide can help a lot of women with breast cancer.

Factors Associated with Cardiorespiratory Fitness in Breast Cancer Survivors from the State of Santa Catarina, Brazil: Cross-Sectional Study

Introduction: Oxygen consumption (VO2) is indicative of cardiorespiratory fitness (CRF) and lower levels are related to a higher risk of total mortality among individuals with cancer whose therapy can have adverse consequences on the cardiovascular system. Objective: To examine the associations of patient-reported sociodemographic, clinical, anthropometric outcomes and functional variables with CRF in 69 women (55±10 years) and to identify whether walking is a predictor of peak VO2 variation in this population with breast cancer (BC). Method: Female BC survivors receiving hormone therapy after two types of surgery (breast-conserving and mastectomy) underwent a CRF test on a cycle ergometer to measure peak VO2. A questionnaire containing sociodemographic, clinical data, patient reported outcomes (PROs) (depressive symptoms, sleep quality, fatigue, body image) and self-reported walking and tests to measure body fat percentage, waist circumference, flexibility and shoulder range of motion (RoM) were performed. Results: Unemployment and retirement were associated with low CRF, as was the use of aromatase inhibitors instead of tamoxifen. Depressive symptoms, worse body image, greater waist circumference, less flexibility and shoulder RoM were also associated with low CRF. Walking duration, controlled for age and body mass index (BMI), is a 13% predictor of peak VO2 variance in this sample. Conclusion: These factors must be considered in understanding the CRF profile of BC survivors. As walking was a predictor of peak VO2 variance, it should be recommended as a type of physical activity for patients with BC using hormone therapy.

Does breast oncoplastic surgery improve quality of life?

Breast Oncoplastic Surgery (OS) has established itself as a safe procedure associated with the treatment of breast cancer, but the term is broad, encompassing procedures associated with breast-conserving surgeries (BCS), conservative mastectomies and fat grafting. Surgeons believe that OS is associated with an increase in quality of life (QOL), but the diversity of QOL questionnaires and therapeutic modalities makes it difficult to assess from the patient's perspective. To answer this question, we performed a search for systematic reviews on QOL associated with different COM procedures, and in their absence, we selected case-control studies, discussing the main results. We observed that: (1) Patients undergoing BCS or breast reconstruction have improved QoL compared to those undergoing mastectomy; (2) In patients undergoing BCS, OS has not yet shown an improvement in QOL, a fact possibly influenced by patient selection bias; (3) In patients undergoing mastectomy with reconstruction, the QoL results are superior when the reconstruction is performed with autologous flaps and when the areola is preserved; (4) Prepectoral implants improves QOL in relation to subpectoral implant-based breast reconstruction; (5) ADM do not improves QOL; (6) In patients undergoing prophylactic mastectomy, satisfaction is high with the indication, but the patient must be informed about the potential complications associated with the procedure; (7) Satisfaction is high after performing fat grafting. It is observed that, in general, OS increases QOL, and when evaluating the procedures, any preservation or repair, or the use of autologous tissues, increases QOL, justifying OS.

Paget's disease of the breast: diagnosis and management

Paget's disease of the breast typically affects postmenopausal women and is associated with an underlying malignancy. Skin changes are a common presenting symptom, as well as a lump, nipple discharge, pain and changes to the nipple shape. Imaging options include ultrasound for women under the age of 35 years or mammogram and ultrasound for women over the age of 40 years. The definitive diagnostic investigation is a tissue core biopsy. Cases are discussed by a multidisciplinary team to decide on the optimal management strategy. Management options are typically surgical and include breast-conserving surgery or mastectomy in addition to oncoplastic techniques. Sentinel lymph node biopsy is performed in all patients undergoing surgery. Adjuvant chemotherapy, radiotherapy or endocrine therapy can be used to treat concomitant invasive disease or ductal carcinoma in situ.

Therapeutic mammoplasty: a "wise" oncoplastic choice-lessons from the largest single-center cohort from Asia

Introduction

The majority of breast cancer patients from India usually present with advanced disease, limiting the scope of breast conservation surgery. Therapeutic mammoplasty (TM), an oncoplastic technique that permits larger excisions, is quite promising in such a scenario and well suited to breast cancer in medium-to-large-sized breasts with ptosis and in some cases of large or multifocal/multicentric tumors. Here, we describe our TM cohort of 205 (194 malignant and 11 benign) patients from 2012 to 2019 treated at a single surgeon center in India, the largest Asian dataset for TM.

Methods

All patients underwent treatment after careful discussions by a multidisciplinary tumor board and patient counseling. We report the clinicopathological profiles and surgical, oncological, cosmetic, and patient-related outcomes with different TM procedures.

Results

The median age of breast cancer patients was 49 years; that of benign disease patients was 41 years. The breast cancer cohort underwent simple (n = 84), complex (n = 71), or extreme (n = 44) TM surgeries. All resection margins were analyzed through intra-operative frozen-section assessment with stringent rad-path analysis protocols. The margin positivity rate was found to be 1.4%. A majority of the cohort was observed to have pT1-pT2 tumors, and the median resection volume was 180 cc. Low post-operative complication rates and good-to-excellent cosmetic scores were observed. The median follow-up was 39 months. We observed 2.07% local and 5.7% distal recurrences, and disease-specific mortality was 3.1%. At median follow-up, the overall survival was observed to be 95.9%, and disease-free survival was found to be 92.2%. The patient-reported outcome measures (PROMs) showed good-to-excellent scores for all types of TMs across BREAST-Q domains.

Conclusion

We conclude that in India, a country where women present with large and locally advanced tumors, TM safely expands the indications for breast conservation surgery. Our results show oncological and cosmetic outcomes at acceptable levels. Most importantly, PROM scores suggest improved overall wellbeing and better satisfaction with the quality of life. For patients with macromastia, this technique not only focuses on cancer but also improves self-image and reduces associated physical discomfort often overlooked by women in the Indian setting. The popularization of this procedure will enable Indian patients with breast cancer to receive the benefits of breast conservation.

Complete Surgical Excision Is Necessary following Vacuum-Assisted Biopsy for Breast Cancer

Vacuum-assisted breast biopsy (VABB) has been replacing excisional biopsy in the treatment of benign breast lesions. Complete surgical excision is still needed for the lesions occasionally diagnosed with breast cancer after VABB. We aimed to characterize residual tumors after VABB and define a subset of patients who do not need surgical excision after VABB. From a retrospective database, we identified patients diagnosed with breast cancer after VABB guided with ultrasonography. Patients who underwent stereotactic biopsies were excluded. We reviewed clinicopathologic data and radiologic findings of the sample. We identified 48 patients with 49 lesions. After surgical excision, the residual tumors were identified in 40 (81.6%) lesions, and there was no residual tumor in nine (18.3%) patients. Imaging studies could not accurately locate residual tumors after VABB. A small tumor size on a VABB specimen was associated with no residual tumor on final pathology. However, residual tumors were identified in four (40%) of 10 lesions with a pathologic tumor size less than 0.5 cm. In conclusion, complete surgical excision remains the primary option for most of the patients diagnosed with breast cancer after VABB. Imaging surveillance without surgery should be carefully applied for selected low-risk patients.

One-year recovery from breast cancer: Importance of tumor and treatment-related factors, resilience, and sociodemographic factors for health-related quality of life

Aim

This study investigated the changes in health-related quality of life from diagnosis to 1 year after diagnosis in breast cancer (BC) patients and the influence of clinical, psychological, and sociodemographic variables. An additional aim was to explore the mediating and moderating effects of resilience on changes in health-related quality of life.

Methods

A longitudinal population-based study was conducted in southern Sweden. Newly diagnosed BC patients filled in measures of health-related quality of life, resilience, and sociodemographic variables at diagnosis (N = 980) and 1 year post-diagnosis (N = 780). Clinical variables were extracted from the Swedish national breast cancer quality registry. Mixed-model analyses were performed.

Results

Most health-related quality of life outcomes declined from diagnosis to 1 year post-diagnosis. Role limitations due to emotional problems remained the same, whereas mental health improved. Lower health-related quality of life outcomes were associated with symptomatic detection and axillary dissection. Patients with a higher TNM stage and histologic grade and estrogen receptor (ER)-negative and human epidermal growth factor 2 (HER2)-positive status, who received chemotherapy, antibody therapy, or bisphosphonate therapy, had a steeper decline in outcomes. Changes in resilience were positively associated with all outcomes but did not mediate or moderate changes in any. Resilience at baseline moderated changes in bodily pain, vitality, and mental health, with higher baseline resilience being associated with a steeper decline, possibly due to floor or ceiling effects. Patients with lower socioeconomic status, educational level, and older age had a lower health-related quality of life.

Conclusion

Physical health-related quality of life among breast cancer patients declined 1 year post-diagnosis, whereas mental health-related quality of life improved. Low resilient patients may be especially vulnerable at diagnosis. Biopsychosocial assessment at diagnosis can help identify patients who may require additional support. A multidimensional treatment plan should be started early to help overcome the problems in everyday activities.

Assessing the relationship between body image and quality of life among rural and urban breast cancer survivors in China

Background

Breast cancer survivors experience altered body image and quality of life (QoL) due to the disease and its treatment. The multidimensional nature of body image and QoL makes their relationships complex. This study aimed to examine the associations between the two concepts in Chinese breast cancer survivors and test whether these associations are moderated by rural–urban residence.

Methods

A cross-sectional design was adopted. Breast cancer survivors were recruited via a convenience sampling method. Two validated questionnaires (the Body Image Self-Rating Questionnaire for Breast Cancer and 36-item Short-Form Health Survey) and questions assessing demographic and clinical covariates were administered. Multiple linear regressions were used to assess the relationship between body image and QoL domains and to examine the moderating effect of rural–urban residence.

Results

In our sample of 354 breast cancer survivors, half (50.28%) lived in rural areas. After adjusting for demographic and clinical variables, better perception of body image-related sexual activity change, role change, and psychological change was significantly associated with better physical (β ranged from − 0.15 to − 0.11, p < 0.05) and mental (β ranged from − 0.46 to − 0.34, p < 0.001) well-being. Better perception of body image-related social and behavior change was significantly associated only with better mental well-being (β ranged from − 0.40 to − 0.33, p < 0.001). The association between body image and mental well-being was much stronger in urban subjects (b = − 0.38, p < 0.001) than in rural subjects (b = − 0.20, p < 0.001).

Conclusions

Our findings suggest that multidimensional body image is associated with physical and mental well-being in Chinese breast cancer survivors. Body image appears to play a larger role in urban breast cancer survivors’ mental well-being. Our results indicate that incorporating interventions that address body image issues would be advantageous for survivorship care to enhance QoL in breast cancer survivors. Furthermore, rural–urban differences should be considered in the strategic design of survivorship care programs in rural and urban settings.

Comparing costs of standard Breast-Conserving Surgery to Oncoplastic Breast-Conserving Surgery and Mastectomy with Immediate two-stage Implant-Based Breast Reconstruction

BACKGROUND

Conventional breast-conserving surgery (C-BCS) has equal oncological outcomes and superior cosmetic and patient-reported outcomes compared to mastectomy with immediate two-stage implant-based breast reconstruction (M-IBR). Oncoplastic breast-conserving surgery (OP-BCS) is increasingly being used, as it often has better cosmetic results and it enables larger tumour resection. However, OP-BCS and M-IBR compared to C-BCS lengthens operative time and might lead to more complications and consequently to additional costs. Therefore, this study aimed to compare costs and complication rates of C-BCS, OP-BCS and M-IBR.

METHODS

This single-centre, retrospective cohort study, calculated costs for all patients who had undergone breast cancer surgery between January 2014 and December 2016. Patient-, tumour- and surgery-related data of C-BCS, OP-BCS and M-IBR patients were retrieved by medical record review. Treatment costs were calculated using hospital financial data. Differences in costs and complications were analysed.

RESULTS

A total of 220 patients were included: 74 patients in the C-BCS, 78 in the OP-BCS and 68 in the M-IBR group. From most expensive to least expensive, differences in total costs were found between C-BCS vs. OP-BCS and C-BCS vs. M-IBR (p=<0.01 and p=0.04, respectively). Costs of OP-BCS and M-IBR were comparable. Complication rates were 5.5% for C-BCS, followed by 17% for OP-BCS, and 34% for M-IBR (p<0.01).

CONCLUSION

Considering total treatment costs, OP-BCS was financially non-inferior to M-IBR, whereas complication rates were higher following M-IBR. Therefore, when considering other benefits of OP-BCS, such as higher patient-reported outcomes and similar oncological outcomes, a shift from M-IBR to BCS using oncoplastic techniques seems justified.

Health-related quality of life among breast cancer patients compared to cancer survivors and age-matched women in the general population in Vietnam

PURPOSE

This study compared the health-related quality of life (HRQoL) of breast cancer (BC) patients, survivors, and age-matched women from the general population in Vietnam to address the paucity of HRQoL research and contribute to the robust assessment of BC screening and care in Vietnam.

METHODS

The standardised EQ-5D-5L instrument was incorporated in an online survey and a hospital-based face-to-face survey, and together with data from the Vietnam EQ-5D-5L norms study. χ2 tests assessed EQ-5D health profile associations and a Tobit regression model investigated the association between overall health status (EQ-VAS/utility scores) and sociodemographic and clinical characteristics.

RESULTS

A total of 309 participants (107 patients undergoing treatment and 202 survivors who had completed treatment) provided usable responses. The dimensions that affected mostly the HRQoL of women with BC were pain/discomfort and anxiety/depression. Current patients and survivors differed significantly regarding HRQoL dimensions of mobility, self-care, usual activities, and anxiety/depression. Their health utilities were 0.74 and 0.84, respectively, compared with 0.91 for age-matched Vietnamese women in the general population (p < 0.001). Treatment status (survivor vs patient), younger age, higher monthly household income, and higher education levels were associated with higher health utility.

CONCLUSIONS

The results point to unmet needs in mental health support and well-being and for attention to be given to the development of a biopsychosocial system of cancer diagnosis, treatment, and care. The results will also inform future assessments of the comparative value for money of interventions intended to impact on breast cancer in Vietnam.

Disparities in Breast-Conserving Therapy for Non-Hispanic American Indian/Alaska Native Women Compared with Non-Hispanic White Women

BACKGROUND

Little is known about the surgical patterns of American Indian/Alaska Native (AI/AN) breast cancer patients. The purpose of this study is to determine whether there are disparities in breast cancer surgery and radiation therapy between non-Hispanic AI/AN (NH-AI/AN) women and non-Hispanic White (NHW) women.

METHODS

Data from the National Program of Cancer Registries of the Centers for Disease Control and Surveillance, Epidemiology, and End Results were used for this cross-sectional study. Female patients with invasive breast cancer diagnosed 2010-2015 were stratified by race/ethnicity, surgical procedure, radiation, and region. Percentage distributions of mastectomy and lumpectomy were compared overall and by region and stage.

RESULTS

From 2010 to 2015 there were 3292 NH-AI/AN women and 165,225 NHW women diagnosed with breast cancer. For early stage (AJCC stage 1 and 2), NH-AI/AN women had overall significantly higher percentage of mastectomy (41% vs 34.4%, p < 0.001) and significantly lower percentage of lumpectomy (59% vs 65.6%) compared with NHW women, without significant differences in post-lumpectomy radiation (71% vs 70%). There were regional variations, notably in the Northern Plains, where the percentage of mastectomy for early-stage disease was 48.9% for NH-AI/AN women versus 35.9% for NHW women, and in Alaska with 47% for NH-AI/AN women versus 33.3% for NHW women (p < 0.001). There were no overall significant differences in type of surgery or radiation for late-stage disease between groups.

CONCLUSION

This is the first study to show disparities in surgical management of NH-AI/AN women with breast cancer. For early-stage disease, NH-AI/AN women undergo a higher percentage of mastectomy. Future clinical directions could focus on the factors that drive awareness, decision-making, and access to breast conservation.

Effects of Integrated Chinese Traditional Medicine and Conventional Western Medicine on the Quality of Life of Breast Cancer Patients: A Systematic Review and Meta-Analysis

BACKGROUND

Traditional Chinese medicine has been widely used, in conjunction with conventional Western medicine, in clinical practice around the world to treat breast cancer. The study systematically reviewed and summarized the quality of life of breast cancer patients treated with integrated treatment method vs. conventional Western medicine.

METHODS

Eight databases including PubMed, EMBASE, Web of Science, the Cochrane Library, Chinese National Knowledge Infrastructure, China Biology Medicine Disc, Chinese Scientific Journal Database, and Wanfang Data knowledge service platform were searched in this study. The retrieval period was set from January 1, 2005, to December 31, 2020.

RESULTS

Twenty-two high-quality publications were included in this study. The total sample size was 1689 patients including 844 in the intervention group receiving traditional Chinese medicine combined with conventional Western medicine and 845 patients in the control group receiving conventional Western medicine only. Compared with the single-used conventional Western medicine treatment, an integrated approach to treat breast cancer can increase quality of life measured by rating scales (SMD = 1.29, 95% CI (1.07, 1.52) and P=0.01) and ranking scales (RR = 1.53, 95% CI (1.39 1.68) and P=0.02) and also decrease adverse reactions measured by rating scales (Z = 10.89, P < 0.05; Group 1: I ² = 9.0%, P=0.258, SMD = 1.03; and Group 2: I ² = 31.6%, P=0.199, SMD = 1.56). For further analysis, chemotherapy with epirubicin exhibited higher quality of life than the chemotherapy without epirubicin among breast cancer patients [Z = 19.80, P < 0.05; Group 1: I ² = 62.4%, P=0.070, SMD = 1.61; and Group 2: I ² = 9.0%, P=0.359, SMD = 1.04]. Despite the heterogeneity, which was due to a portion of relative low-quality literature or other factors, the results were satisfactory. In terms of secondary results, the patients with lower tumor markers (CEA and CA153) had better efficiency in quality of life with a statistically significant difference (SMD = 1.39, 95% CI: 1.10,1.67) for rating scales. In addition, secondary results related to high incidence of gastrointestinal adverse reactions (RR = 1.33, 95% CI (1.20, 1.48)) and the traditional Chinese medicine syndrome (RR = 1.50, 95% CI (1.28, 1.80))showed lower quality of life in the intervention group than the control group for ranking scales.

CONCLUSION

Traditional Chinese medicine, when used in conjunction with the conventional Western medicine, could be an effective way in improving the quality of life and alleviating incidence of associated adverse symptoms such as gastrointestinal adverse reactions, value of tumor markers, and the incidence of traditional Chinese medicine syndrome. Further investigation of larger and methodologically sound trials with longer follow-up periods and appropriate comparison groups is needed.

Invisible Surgery Concept and Scenario Strategy: How to Get the Best Aesthetic Results in Oncoplastic Breast-Conserving Surgery

SUMMARY

The authors believe that oncoplastic breast surgery has to achieve the best possible aesthetic results. In this article, they propose the concept of "invisible surgery." This is a combination of certain oncoplastic techniques that allows for restoration of the original appearance of the breast without obvious scars on the breast. Further, the authors classify the techniques as follows: the "level 1 technique," with contour approach; the "from inside" technique; the lateral parenchymal flap; the axillary subcutaneous adipofascial flap; the rotational lateral thoracic flap; regional island perforator flaps (lateral intercostal artery perforator, lateral thoracic artery perforator, anterior intercostal artery perforator, and medial intercostal artery perforator flaps); and the nipple-sparing mastectomy with immediate expander reconstruction. These techniques were combined by internal logic-one can move from one to another according to the preoperative planning and margins status during the operation. They call their approach the "scenario strategy." The authors have performed 138 operations in 137 patients using this approach. Most of them involved the "from inside" technique and perforator flaps. The average tumor size was 2.4 cm, and the average specimen weight was 43.2 g. The total rate of complications was 14.6 percent. According to this concept, the surgery should be performed in such way that breast appearance will not change. It should be planned as one would plan a staged procedure, taking into account possible changes in the scenario during the operation to achieve the best possible aesthetic result.

Radiological Underestimation of Tumor Size Influences the Success Rate of Re-Excision after Breast-conserving Surgery

Objective

Failure to achieve adequate margins after breast-conserving surgery often leads to re-excision, either by repeat breast-conserving surgery (BCS) or by mastectomy. Despite the high frequency of this problem, the success rate of achieving adequate margins by repeat BCS is not well documented. The objective of this study was to determine the success rate of repeat BCS and identify the factors influencing that rate.

Materials and Methods

A retrospective review was performed of all women undergoing repeat BCS for inadequate margins after initial BCS in our breast unit between 2013 and 2019. Univariate and multivariate analyses were carried out to identify the factors influencing how often adequate margins were achieved after repeat BCS.

Results

One hundred fifty-four patients underwent repeat BCS after initially inadequate margins, of which adequate margins were achieved in 82%. Patients with successful repeat BCS had smaller tumors, had less underestimation of tumor size on imaging, and were less likely to have had cavity shaves taken at their initial BCS. A tumor size more than 50% larger than predicted by imaging was independently associated with failure of repeat BCS in multivariate analysis (odds ratio: 3.6, 95% CI: 1.41-9.20, p = 0.007). Underestimation of tumor size by imaging was commoner and more extensive in patients with larger tumors and those with ductal carcinoma in situ.

Conclusion

Re-excision by cavity shaves has a high success rate and should be offered to all patients who are deemed suitable for the procedure. Patients whose tumors are more than 50% larger than predicted by imaging should be counseled about the higher risk of failure.

Quality of Life and Sexual Functioning of Women after Breast Cancer Surgery

BACKGROUND: Women with breast cancer can experience changes in sexual functioning and body images that can seriously affect their quality of life. AIM: The aim of this research was to study the quality of life and sexual functioning of women after a mastectomy and after a breast-conserving surgery and to compare post-operative quality of life. SUBJECTS AND METHODS: This cross-sectional study included 204 participants, 101 patients after a mastectomy and 103 patients after a quadrantectomy. The research was conducted using the Croatian version of the questionnaire of the European Organization for Research and Treatment of Breast Cancer, the questionnaire with the breast cancer module EORTC QLQ - BR 23. RESULTS: On the EORTC QLQ –BR23 scale, participants with mastectomy rated their sexual functioning (p < 0.001), sexual pleasure (p < 0.001), and systemic side effects (p = 0.04) lower comparing to women after breast-conserving surgery. The overall functionality scale was significantly lower (p = 0.03) for women who underwent mastectomy compared to those who underwent breast-conserving surgery. Participants under 51 years of age had worse body image 1 month after mastectomy (p = 0.006), while sexual functioning was better (p = 0.03) than in older age groups. In breast-conserving surgery group, 1 month after surgery, participants in the age group of 61 years and older assessed body image better (p = 0.04) than in the younger age group. Sexual functioning was rated better by women aged 51–60 years (p = 0.03). CONCLUSION: Results of this study show that women after breast conserving surgery have better quality of life, better sexual functioning and less side effects of systemic therapy compared to women after mastectomy. The type of surgery, patient’s age and time passed after completion of treatment are important factors which influence sexual functioning and quality of life in breast cancer survivors.

Socio-Demographic and General Health Factors Associated with Quality of Life in Long-Term Breast Cancer Survivors from Southwestern Poland

Background: Identification of factors associated with quality of life (QOL) in breast cancer survivors can contribute to better functioning in this group of patients. The study aimed to assess the association between QOL and anthropometric, sociodemographic, and medical characteristics in postmastectomy women from southwestern Poland, 9.4 (±6.5) years after completed treatment. Materials and methods: QOL was estimated with the SF-36v2 questionnaire in 250 survivors aged 62.8 (±8.0) years with previously histologically confirmed invasive breast cancer. Results: Women in this study rated their overall QOL with an average of 60.7 (±17.9), Mental Component Summary of 62.8 (±19.8), and Physical Component Summary of 57.5 (±18.8) points. The use of multivariate regression analysis revealed that depression, chronic diseases, abdominal obesity, and pregnancy history have a statistically significant negative effect on the QOL of women after mastectomy, whereas participation in regular physical activity, living with a partner, the education level ≥ 12 years, and living in the city were associated with a higher QOL assessment. There were no significant relationships between QOL and the age, time since surgery, type of treatment, smoking, and occupational status of the patients. Conclusions: Health education, greater social support, specialist care in the treatment of comorbidities, and propagation of a physically active lifestyle can improve the physical and mental functioning of breast cancer survivors long after diagnosis and treatment.

Psychosocial impact of mastectomy on female breast cancer patients presenting at an academic radiotherapy oncology centre in Ghana

Introduction:

Mastectomy is a treatment option for patients diagnosed with breast cancer. There is very limited research into the psychosocial impact of mastectomy on female breast cancer patients, especially in the sub-Saharan African setting which has unique cultural norms. The study aimed at assessing the psychosocial impact of mastectomy on female breast cancer patients attending a radiotherapy/oncology centre in Ghana.

Methods:

A cross-sectional design was used to undertake this study. A total of 80 female mastectomy breast cancer patients participated in this study. A semi-structured questionnaire was used for data collection over a 5-month period, January to May 2018. The data collected were analysed with Statistical Package for Social Science (SPSS) version 22.

Results:

Most of the participants were adversely affected psychologically and emotionally by mastectomy. In particular, many (56·7%) agreed that they felt less feminine, and 71% reported they experienced psychological distress as a result of their mastectomy, while 63% of them reported loss of self-confidence. A large proportion of them (51, 63·8%) agreed that their lifestyles had changed following mastectomy, while 58% of them admitted that they felt treated as outcasts by society, and 75% resorted to the use of breast prostheses to reduce attention.

Conclusion:

The study revealed that mastectomy for breast cancer patients had a negative impact on their psychological, emotional and social well-being. The availability of affordable breast prostheses, involvement of clinical psychologists in the care of post-mastectomy women, provision of emotional, psychological and even financial support could alleviate the psychosocial impact of affected women.

Discordance in clinical versus pathological staging in breast cancer: Are we undermining the significance of accurate preoperative staging in the present era?

BACKGROUND

The present era of individualized treatment for breast cancer is influenced by the initial disease status including the anatomical extent, grade, and receptor status. An accurate preoperative staging is the basis of treatment planning and prognostication. Our study aims to determine the discordance between the preoperative clinical and the postoperative pathological stages of breast cancer patients.

METHODOLOGY

The medical records of all non-metastatic breast cancer patients from January 2017 to December 2018 who underwent upfront surgery were reviewed. They were staged as per the eighth AJCC and the concordance between the clinical (c) and pathological T (tumor), N (nodal), and final AJCC stage was studied. A Chi-square test was used to determine factors that significantly correlate with disease discordance.

RESULTS

A total of 307 breast cancer patients were analyzed. Among these, 43.3% were hormone receptor-positive, 30.6% were Her2 positive and 26% were triple-negative. Overall stage discordance was seen in 48.5% (n = 149) patients (upstaging in 22.1%, downstaging in 26.4%). The discordance rate was 48.9% for T stage (cT versus pT) and 57.4% for N stage (cN versus pN). Among patients with clinically node-negative disease, 53.4% were found to have positive nodes on histopathology, while 27.2% had vice versa. Overall, the factors associated with upstaging were ER-positive, Her2 positive and triple-negative status (all p < 0.05), while none of the factors showed significant association with downstaging.

CONCLUSIONS

About half of breast cancer patients had discordance between clinical and pathological staging with higher discordance in the nodal stage. This changes the disease prognosis, and may also affect the offered surgical treatment and radiotherapy. Thus highlighting the need for a precise pre-operative staging. Also, this information will aid clinicians in discussions with patients, keeping in mind the likelihood of change in disease staging and management.

The Influence of Rehabilitation on Quality of Life in Breast Cancer Survivors: A Clinical Study

Background: Breast cancer survivors report negative impacts of cancer, augmented by specific vulnerabilities to body changes, negative self-assessment, and quality-of-life concerns. The main objective of our work was to test the effect of a rehabilitation program on breast cancer patients by evaluating the change in their physical well-being during an outpatient rehabilitation setting and, subsequently, in a home rehabilitation setting, considering the individual personality profile. Methods: Patients who underwent total mastectomy with breast prostheses or tissue expanders were enrolled. Outcome assessments (Pain, Quality of Life, Personality traits for the Minnesota Multiphasic Personality Inventory-2) before treatment (T0), at the end of the rehabilitative treatment (T1 = 10 sessions 2/week, one hour/each), and after two months of follow-up (T2) were performed. Results: The data of 38 included patients were analyzed. The quadratic trend of the Visual Analogue Scale can be explained by the fact that patients have a strong reduction in the perceived pain immediately after rehabilitation in the clinic. This reduction remains constant for the home period of the rehabilitation. The personality profiles of all the participants were substantially valid. Only three patients obtained scores higher than 65 points. Conclusions: The study evidenced that in the initial phase of the rehabilitation, psychological traits such as anxiety, depression, and preoccupation could have a strong association especially with the autonomous functions and the perceived physical symptoms. However, during the therapeutic process, this association decreased and these decrements were higher when patients performed their rehabilitation at home, in a more familiar and comfortable setting.

Factors predicting residual disease on re-excision after breast conserving surgery

INTRODUCTION

Breast conserving surgery is the standard of care for early breast cancer, however in a quarter of patients, satisfactory margins are not achieved, usually leading to re-excision. Residual disease is found in less than half of these re-excisions, leading to increased morbidity, poorer cosmesis and increased cost, possibly with no oncological benefit. Our study aimed to identify a group of patients with unsatisfactory margins but a low risk of residual disease, who may be able to avoid re-excision.

METHODS AND MATERIALS

All patients from our unit undergoing re-excision for unsatisfactory margins after breast conserving surgery between January 2013 and October 2019 were identified. Pathological factors predicting residual disease were investigated using univariable and multivariable analysis.

RESULTS

220 patients were included. 90 (41 %) had residual disease. Residual disease was more likely in those having mastectomy than cavity shaves (61 % vs 32 %, p < 0.0001). Residual disease increased in a linear fashion with number of involved margins and with increasing tumour size. Tumour size <20 mm (p = 0.045), a pathological to radiological tumour size ratio less than 1.5 (p < 0.0001) and disease-free cavity shaves taken at initial surgery (p = 0.041) were all independent predictors of a low chance of residual disease on multivariable analysis. Patients with all three factors had a 14 % chance of residual disease.

CONCLUSIONS

More than half of patients undergo potentially unnecessary re-excision, and patients with small, radiologically obvious tumours are less likely to have residual disease. The decision on re-excision should include these factors in addition to the margin status.

Prediction of quality of life in early breast cancer upon completion of adjuvant chemotherapy

Quality of life (QoL) is a complex, ordinal endpoint with multiple conditioning factors. A predictive model of QoL after adjuvant chemotherapy can support decision making or the communication of information about the range of treatment options available. Patients with localized breast cancer (n = 219) were prospectively recruited at 17 centers. Participants completed the EORTC QLQ-C30 questionnaire. The primary aim was to predict health status upon completion of adjuvant chemotherapy adjusted for multiple covariates. We developed a Bayesian model with six covariates (chemotherapy regimen, TNM stage, axillary lymph node dissection, perceived risk of recurrence, age, type of surgery, and baseline EORTC scores). This model allows both prediction and causal inference. The patients with mastectomy reported a discrete decline on all QoL scores. The effect of surgery depended on the interaction with age. Women with ages on either end of the range displayed worse scores, especially with mastectomy. The perceived risk of recurrence had a striking effect on health status. In conclusion, we have developed a predictive model of health status in patients with early breast cancer based on the individual's profile.

Survival After Breast Conservation vs Mastectomy Adjusted for Comorbidity and Socioeconomic Status: A Swedish National 6-Year Follow-up of 48 986 Women

Question

Does breast conservation offer a survival benefit compared with mastectomy when results are adjusted for main confounders such as comorbidity and socioeconomic status?

Findings

In this large cohort study based on prospectively collected national data from 48 986 patients with breast cancer, overall and breast cancer–specific survival were significantly better after breast-conserving surgery followed by radiotherapy than after mastectomy with or without radiotherapy despite stepwise adjustment for tumor characteristics, treatment, demographics, comorbidity, and socioeconomic background.

Meaning

Breast conservation seems to offer a survival benefit independent of measured confounders and should be given priority if both breast conservation and mastectomy are valid options.

Importance

Cohort studies show better survival after breast-conserving surgery (BCS) with postoperative radiotherapy (RT) than after mastectomy (Mx) without RT. It remains unclear whether this is an independent effect or a consequence of selection bias.

Objective

To determine whether the reported survival benefit of breast conservation is eliminated by adjustment for 2 pivotal confounders, comorbidity and socioeconomic status.

Design, Setting, and Participants

Cohort study using prospectively collected national data. Swedish public health care; nationwide clinical data from the National Breast Cancer Quality Register, comorbidity data from Patient Registers at the National Board of Health and Welfare, and individual-level education and income data from Statistics Sweden. The cohort included all women diagnosed as having primary invasive T1-2 N0-2 breast cancer and undergoing breast surgery in Sweden from 2008 to 2017. Data were analyzed between August 19, 2020, and November 12, 2020.

Exposures

Locoregional treatment comparing 3 groups: breast-conserving surgery with radiotherapy (BCS+RT), mastectomy without radiotherapy (Mx-RT), and mastectomy with radiotherapy (Mx+RT).

Main Outcomes and Measures

Overall survival (OS) and breast cancer–specific survival (BCSS). Main outcomes were determined before initiation of data retrieval.

Results

Among 48 986 women, 29 367 (59.9%) had BCS+RT, 12413 (25.3%) had Mx-RT, and 7206 (14.7%) had Mx+RT. Median follow-up was 6.28 years (range, 0.01-11.70). All-cause death occurred in 6573 cases, with death caused by breast cancer in 2313 cases; 5-year OS was 91.1% (95% CI, 90.8-91.3) and BCSS was 96.3% (95% CI, 96.1-96.4). Apart from expected differences in clinical parameters, women receiving Mx-RT were older, had a lower level of education, and lower income. Both Mx groups had a higher comorbidity burden irrespective of RT. After stepwise adjustment for all covariates, OS and BCSS were significantly worse after Mx-RT (hazard ratio [HR], 1.79; 95% CI, 1.66-1.92 and HR, 1.66; 95% CI, 1.45-1.90, respectively) and Mx+RT (HR, 1.24; 95% CI, 1.13-1.37 and HR, 1.26; 95% CI, 1.08-1.46, respectively) than after BCS+RT.

Conclusions and Relevance

Despite adjustment for previously unmeasured confounders, BCS+RT yielded better survival than Mx irrespective of RT. If both interventions are valid options, mastectomy should not be regarded as equal to breast conservation.

Effects of evidence-based nursing on psychological well-being, postoperative complications and quality of life after breast cancer surgery

OBJECTIVE

To evaluate the influence of evidence-based nursing (EBN) on psychological well-being, postoperative complications and quality of life (QOL) after breast cancer (BC) surgery.

METHODS

A total of 263 patients with BC who were surgically treated in Zhejiang Provincial People's Hospital from May, 2018 to August, 2019 were as assigned to observation group (EBN, n=142) and control group (routine nursing care, n=121). Clinical indicators and any complications after intervention were recorded. And the exercise compliance in the affected limbs was evaluated. Barthel index (BI), self-rating anxiety scale (SAS) and self-rating depression scale (SDS), Pittsburgh Sleep Quality Index (PSQI) were employed for the assessment of self-care ability, psychological status, and sleep quality, respectively. In addition, we utilized the numerical rating scale (NRS) to evaluate postoperative pain, the functional assessment of cancer therapy-breast (FACT-B) scale to assesse the quality of life (QOL), and the self-made questionnaire to quantify patient satisfaction.

RESULTS

After intervention, the observation group presented greater improvement in symptoms, higher exercise compliance and BI scores, as well as lower SAS, SDS, and PSQI scores; the incidence of postoperative pain and complications decreased in observation group, and FACT-B scores and patient satisfaction increased.

CONCLUSION

EBN is effective in relieving symptoms, reducing negative emotions and postoperative complications, as well as enhancing the QOL of patients undergoing BC surgery.
