Breast reconstruction after mastectomy for breast cancer

Reconstruction trends in New York City: A multi-decade, multi-institutional experience before and after the implementation of the Breast Cancer Provider Discussion Law

INTRODUCTION

The potential benefits of breast reconstruction for achieving greater patient satisfaction, wellbeing, and functional outcomes after mastectomy have been widely acknowledged. However, sociodemographic and economic disparities exist in accessing reconstruction. This study aimed to characterize the influence of various factors on access to reconstruction and investigate the impact of the Breast Cancer Provider Discussion Law (BCPDL), legislation that mandates patient education and referral to plastic surgery at the time of breast cancer diagnosis, on utilization of reconstructive services.

METHODS

Retrospective chart review was performed to collect data on patients who underwent mastectomy at two institutions within the New York-Presbyterian system from 1998-2019. Sociodemographic, past medical history, and treatment approach information were recorded. Interrupted time series analysis and logistic regression were used for statistical analysis.

RESULTS

The cohort included 6122 patients, of which 3737 (61.04%) underwent reconstruction and 2385 (38.96%) did not. Older age, Medicaid/Medicare insurance, higher tumor staging, and Asian American/Pacific Islander identity were negative predictors of undergoing reconstruction. The interrupted time series analysis of the years before and the years after implementation of the 2010 BCPDL revealed that while there was an immediate increase in the proportion of patients who received reconstruction, the effects were not sustained.

CONCLUSION

Our data indicates that patient-physician communication alone may not be sufficient to bridge the gap in reconstructive care. This study highlights the need for consistent plastic surgery referral for sustained equal access to reconstructive services.

Reconstructive breast implant-related infections: Prevention, diagnosis, treatment, and pearls of wisdom

Implant-based reconstructions are increasingly utilized following mastectomy in the prevention and treatment of breast cancer. However, these implants are associated with a high rate of infection, which is a major complication that can lead to implant removal, delay in adjuvant radiation and chemotherapy, and increase in health care costs. Early clinical signs and symptoms of infection, such as erythema, warmth, and tenderness, are challenging to discern from expected postsurgical responses. Furthermore, when atypical features are present or the patient's condition does not improve on adequate antimicrobials, the clinician should be prompted to consider an alternative noninfectious etiology. Herein we highlight the key elements of the preventive, diagnostic, and multidisciplinary therapeutic approach to salvaging the infected breast implant; review several infectious disease mimickers; and provide many pearls of wisdom that the practicing clinician must be familiar with and be able to manage in an effective and successful manner.

Disparities in Postmastectomy Reconstruction Use among American Indian and Alaska Native Women

BACKGROUND

American Indian/Alaska Native (AI/AN) breast cancer patients undergo postmastectomy reconstruction (PMR) infrequently relative to non-Hispanic White (NHW) patients. Factors associated with low PMR rates among AI/AN women are poorly understood. The authors sought to describe factors associated with this disparity in surgical care.

METHODS

A retrospective cohort study of the National Cancer Database (2004 to 2017) identified AI/AN and NHW women, aged 18 to 64, who underwent mastectomy for stage 0 to III breast cancer. Patient characteristics, annual PMR rates, and factors associated with PMR were described with univariable analysis, the Cochran-Armitage test, and multivariable logistical regression.

RESULTS

A total of 414,036 NHW and 1980 AI/AN women met inclusion criteria. Relative to NHW women, AI/AN women had more comorbidities (20% versus 12%; Charlson Comorbidity Index ≥ 1; P < 0.001), had nonprivate insurance (49% versus 20%; P < 0.001), and underwent unilateral mastectomy more frequently (69% versus 61%; P < 0.001). PMR rates increased over the study period, from 13% to 47% for AI/AN women and from 29% to 62% for NHW women ( P < 0.001). AI/AN race was independently associated with decreased likelihood of PMR (OR, 0.62; 95% CI, 0.56 to 0.69). Among AI/AN women, decreased likelihood of PMR was significantly associated with older age at diagnosis, more remote year of diagnosis, advanced disease (tumor size >5 cm, positive lymph nodes), unilateral mastectomy, nonprivate insurance, and lower educational attainment in patient's area of residence.

CONCLUSIONS

PMR rates among AI/AN women with stage 0 to III breast cancer have increased, yet they remain significantly lower than rates among NHW women. Further research should elicit AI/AN perspectives on PMR, and guide early breast cancer detection and treatment.

Unraveling Drug Delivery from Cyclodextrin Polymer-Coated Breast Implants: Integrating a Unidirectional Diffusion Mathematical Model with COMSOL Simulations

Breast cancer ranks among the most commonly diagnosed cancers worldwide and bears the highest mortality rate. As an integral component of cancer treatment, mastectomy entails the complete removal of the affected breast. Typically, breast reconstruction, involving the use of silicone implants (augmentation mammaplasty), is employed to address the aftermath of mastectomy. To mitigate postoperative risks associated with mammaplasty, such as capsular contracture or bacterial infections, the functionalization of breast implants with coatings of cyclodextrin polymers as drug delivery systems represents an excellent alternative. In this context, our work focuses on the application of a mathematical model for simulating drug release from breast implants coated with cyclodextrin polymers. The proposed model considers a unidirectional diffusion process following Fick's second law, which was solved using the orthogonal collocation method, a numerical technique employed to approximate solutions for ordinary and partial differential equations. We conducted simulations to obtain release profiles for three therapeutic molecules: pirfenidone, used for preventing capsular contracture; rose Bengal, an anticancer agent; and the antimicrobial peptide KR-12. Furthermore, we calculated the diffusion profiles of these drugs through the cyclodextrin polymers, determining parameters related to diffusivity, solute solid-liquid partition coefficients, and the Sherwood number. Finally, integrating these parameters in COMSOL multiphysics simulations, the unidirectional diffusion mathematical model was validated.

Geographic variation in breast reconstruction surgery after mastectomy for females with breast cancer in Alberta, Canada

BACKGROUND

Breast cancer is the most common cancer affecting females in Canada, and about half of females with breast cancer are treated with mastectomy. We sought to evaluate geographic variation in breast reconstruction surgery in Alberta, Canada.

METHODS

Using linked population-based administrative databases, we extracted data on all Alberta females aged 18 years and older who were diagnosed with breast cancer and treated with mastectomy during 2004-2017. Analyses included regression modelling of odds of reconstruction at 1 year and a spatial scan to identify geographic clusters of lower numbers of reconstruction.

RESULTS

A total of 16 198 females diagnosed with breast cancer were treated with a mastectomy, and 1932 (11.9%) had reconstruction within 1 year postmastectomy. Those with reconstruction were more likely to be younger (adjusted odds ratio [OR] 16.7, 95% confidence interval [CI] 13.7-20.3; aged 21-44 yr v. ≥ 65 yr) and were less likely to be from lower-income neighbourhoods. They were more likely to have at least 1 comorbidity and were more likely to have advanced stages of cancer and to require chemotherapy (adjusted OR 0.55, 95% CI 0.47-0.65) or radiotherapy after mastectomy (adjusted OR 0.59, 95% CI 0.39-0.87) than females without reconstruction. We identified rural northern and southeastern clusters with frequencies of reconstruction that were 69.6% and 41.6% of what was expected, respectively.

CONCLUSION

We found an overall postmastectomy rate of breast reconstruction of 11.9%, and we identified geographic variation. Predictors of reconstruction in Alberta were similar to those previously described in the literature, specifically with patients in rural communities having lower rates of reconstruction than their urban counterparts. These results suggest that further interventions are required to identify the specific barriers to reconstruction within rural communities and to create strategies to ensure equitable access to all residents.

BREAST-Q-Based Survey of the Satisfaction and Health Status of Patients with Breast Reconstruction

AIMS

To explore the patients' satisfaction and health-related quality of life (HRQOL) of patients who received reconstruction after breast cancer surgery using the BREAST-Q questionnaire and further investigate the influencing risk factors.

METHODS

This cross-sectional study enrolled patients who underwent first-ever breast reconstruction after unilateral or bilateral mastectomy at the Breast Surgery Department of First Affiliated Hospital of Zhengzhou University or People's Hospital of Zhengzhou between January 2016 and December 2021. Multivariable linear regression analysis was used to analyze the risk factors.

RESULTS

A total of 202 participants were included. Age of >45 years (vs.≤35 years, β = - 3.74, P < 0.001) was an independent risk factor influencing the satisfaction degree score. Age between 36 and 45 years (vs. ≤35 years, β = - 0.26, P < 0.001), age of >45 years (vs. ≤35 years, β = - 0.45, P < 0.001), nipple-preserving mastectomy (NSM)/ skin-preserving mastectomy (SSM) + sentinel lymph node dissection + prosthesis implantation + contralateral breast augmentation (vs. NSM/SSM + sentinel lymph node dissection + prosthesis implantation, β = - 0.16, P=0.012), and the use of small intestinal submucosa (SIS) matrix (β = 0.13, P = 0.044) were independent risk factors influencing the HRQOL scores.

CONCLUSION

Age, the surgical procedure, and the use of matrix were associated with the satisfaction degree and HRQOL after breast reconstruction in patients receiving mastectomy.

The International Awareness of Breast Reconstruction

Background

To our knowledge, this is the first and largest study conducted to collect data among surgeons worldwide about breast reconstruction. We have aimed to collect data about breast reconstruction worldwide, the most popular breast reconstruction techniques, and the barriers behind the low rate of breast reconstruction according to surgeons.

Methodology

A comparative cross-sectional design was used in this study. A prepared questionnaire, which was developed after reviewing the literature review conducted for this study, was used to collect data. The questionnaire is multiple choice. It was distributed among surgeons online.

Results

The study includes 812 participants who live all over the world, representing 79 countries. More than a third of surgeons perform less than 10 breast reconstructions per year (33.38%), and 45.86% of them think that immediate surgery is the most frequent practice. A higher percentage of participants prefer implants over autologous reconstruction as a technique for breast reconstruction (54.9%). Moreover, 39.02% of participants shared that a lack of knowledge about the availability of breast reconstruction was a reason for refusing the surgery.

Conclusions

This study demonstrates that the breast reconstruction rate is still low and that most surgeons prefer implants that are performed immediately. The lack of knowledge among patients about the availability of breast reconstruction is the most common reason for refusing reconstruction. Therefore, there is a need to increase patient awareness about the availability of this surgery.

Prophylactic Antibiotics for Deep Inferior Epigastric Perforator Flap Breast Reconstruction: A Comparison between Three Different Duration Approaches

There is no consensus on the duration of prophylactic antibiotic use for autologous breast reconstruction after mastectomy. We attempted to standardize the use of prophylactic antibiotics after mastectomy using a deep inferior epigastric perforator flap for the breast reconstruction procedure.

Methods

This retrospective case series included 108 patients who underwent immediate breast reconstruction with a deep inferior epigastric perforator flap at the Ditmanson Medical Foundation Chia-Yi Christian Hospital between 2012 and 2019. Patients were divided into three groups based on the duration of prophylactic antibiotic administration (1, 3, and >7 days) for patients with drains. Data were analyzed between January and April 2021.

Results

The prevalence of surgical site infection in the breast was 0.93% (1/108), and in the abdomen it was 0%. The patient groups did not differ by age, body mass index, smoking status, or neoadjuvant chemotherapy. Only one patient experienced surgical site infection in the breast after half-deep necrosis of the inferior epigastric perforator flap. There were no significant differences in surgical site infection based on the duration of prophylactic antibiotic use. The operation time, methods of breast surgery, volume of fluid drainage in the first 3 days of the abdominal and breast drains, and day of removal of the abdominal and breast drains did not affect surgical site infection.

Conclusion

Based on these data, we do not recommend extending prophylactic antibiotics beyond 24 hours in deep inferior epigastric perforator reconstruction.

Using Virtual Reality for Deep Inferior Epigastric Perforator Flap Preoperative Planning

This study was designed to compare VR stereoscopical three-dimensional (3D) imaging with two-dimensional computed tomography angiography (CTA) images for evaluating the abdominal vascular anatomy before autologous breast reconstruction.

Methods

This prospective case series feasibility study was conducted in two tertiary medical centers. Participants were women slated to undergo free transverse rectus abdominis muscle, unilateral or bilateral deep inferior epigastric perforator flap immediate breast reconstruction. Based on a routine CTA, a 3D VR model was generated. Before each procedure, the surgeons examined the CTA and then the VR model. Any new information provided by the VR imaging was submitted to a radiologist for confirmation before surgery. Following each procedure, the surgeons completed a questionnaire comparing the two methods.

Results

Thirty women between 34 and 68 years of age were included in the study; except for one, all breast reconstructions were successful. The surgeons ranked VR higher than CTA in terms of better anatomical understanding and operative anatomical findings. In 72.4% of cases, VR models were rated having maximum similarity to reality, with no significant difference between the type of perforator anatomical course or complexity. In more than 70% of the cases, VR was considered to have contributed to determining the surgical approach. In four cases, VR imaging modified the surgical strategy, without any complications.

Conclusions

VR imaging was well-accepted by the surgeons who commented on its importance and ease compared with the standard CTA presentation. Further studies are needed to determine whether VR should become an integral part of preoperative deep inferior epigastric perforator surgery planning.

Racial Disparities in Breast Reconstruction at a Comprehensive Cancer Center

INTRODUCTION

Breast reconstruction after a mastectomy is an important component of breast cancer care that improves the quality of life in breast cancer survivors. African American women are less likely to receive breast reconstruction than Caucasian women. The purpose of this study was to further investigate the reconstruction disparities we previously reported at a comprehensive cancer center by assessing breast reconstruction rates, patterns, and predictors by race.

METHODS

Data were obtained from women treated with definitive mastectomy between 2000 and 2012. Sociodemographic, tumor, and treatment characteristics were compared between African American and Caucasian women, and logistic regression was used to identify significant predictors of reconstruction by race.

RESULTS

African American women had significantly larger proportions of public insurance, aggressive tumors, unilateral mastectomies, and modified radical mastectomies. African American women had a significantly lower reconstruction rate (35% vs. 49%, p < 0.01) and received a larger proportion of autologous reconstruction (13% vs. 7%, p < 0.01) compared to Caucasian women. The receipt of adjuvant radiation therapy was a significant predictor of breast reconstruction in Caucasian but not African American women.

CONCLUSIONS

We identified breast reconstruction disparities in rate and type of reconstruction. These disparities may be due to racial differences in sociodemographic, tumor, and treatment characteristics. The predictors of breast reconstruction varied by race, suggesting that the mechanisms underlying breast reconstruction may vary in African American women. Future research should take a target approach to examine the relative contributions of sociodemographic, tumor, and treatment determinants of the breast reconstruction disparities in African American women.

Postoperative antibiotics and infection rates after implant-based breast reconstruction: A systematic review and meta-analysis

Purpose

Infection is the most common complication following breast implant surgery. Nevertheless, the systematic administration of antibiotics after breast implant surgery has been subjected to controversial debate. In this study, we sought to elucidate the association between infection and the use of antibiotics as an aftermath of breast implantation surgical procedures.

Methods

Relevant studies were identified from PubMed, Web of Science, and EMBASE search mining. The extracted data included study type, basic characteristics, administrated antibiotic information, and clinical outcomes. Random-effects models were utilized to estimate outcomes, while study quality, statistical bias, and heterogeneity were also analyzed.

Results

A total of 7 studies involving a total of 9,147 subjects were included. The results demonstrated that the use of antibiotics after breast implantation reduced the incidence of infection (risk ratio [RR]: 0.65, 95% CI, 0.46–0.90). Nevertheless, smoking, obesity and diabetes type II are risk factors for postoperative infections. Sensitivity analysis verified the robustness of the results.

Conclusions

Our study identified the administration of antibiotics after breast implantation as an intervention that decreased the incidence of infection. Smoking, obesity, and diabetes type II are risk factors for postoperative infections. These findings strongly suggest that timely and effective antibiotic interventions will be crucial in future clinical practice, which may reduce the risk of postoperative infection following breast implantation.

Human fibroblasts facilitate the generation of iPSCs-derived mammary-like organoids

Background

Breast cancer is the most common malignancy in women worldwide, and its treatment largely depends on mastectomy. Patients after mastectomy suffer from crippled body image, self-esteem, and quality of life. Post-mastectomy breast reconstruction can improve patients’ psychosocial health. Although silicone and fat have been widely used for breast reconstruction, they have remarkable limitations. Our study aimed to establish an improved method for breast reconstruction from human-induced pluripotent stem cells (iPSCs).

Methods

We used a two-step procedure to induce mammary-like organoids (MLOs) from iPSCs and applied transcriptome sequencing to analyze the gene expression profiles during the development process from embryoid bodies (mEBs) to MLOs. Moreover, we evaluated the in vitro effect of fibroblasts cell line HFF (human foreskin fibroblasts) on the size and morphology of MLOs and explored the in vivo effect of HFF on regeneration rate of MLOs.

Results

MLOs had a similar gene expression profile and morphogenesis as the normal mammary glands. Furthermore, the addition of HFF increases the branching ratio and organoid diameters and facilitates the formation of multiple cell layers duct-like structures in MLOs in vitro. Finally, orthotopical transplantation of the MLOs to cleared mammary gland fad pad of NSG mice showed that HFF increases the formation of mammary gland-like structures.

Conclusions

Fibroblasts facilitate iPSC-derived MLOs to generate mammary gland-like structures in both in vitro and in vivo conditions. Our findings lay a foundation for breast reconstruction by using iPSCs.

Impact of Immediate and Delayed Breast Reconstruction on Quality of Life of Breast Cancer Patients

A mastectomy affects the psychological, social, and sexual well-being of patients. Research has confirmed that breast reconstruction is important for improving the quality of life in patients with breast cancer. The aim of this study was to assess the quality of life of patients who underwent a mastectomy followed by immediate or delayed breast reconstruction. This prospective study was conducted from January 2018 to March 2020 at the Clinical Hospital Center Osijek, using the health questionnaire SF-36. The study included 79 patients. The results of the study showed that patients who underwent a mastectomy had the lowest scores in the domain of restriction due to physical difficulties, 18.8 (6.3−31.3), in physical functioning and limitation due to emotional difficulties, 16.7 (8.3−33.3), in mental health. In immediate breast reconstruction, patients rated better physical health (p < 0.001), while patients who underwent delayed breast reconstruction rated their mental health worse (p < 0.001) as measured by the SF-36 questionnaire. Conclusion: The results of this study show that patients without breast reconstruction rated their quality of life worse than patients who underwent immediate and delayed breast reconstruction after mastectomy. There is no difference in the quality of life between patients who underwent immediate and delayed breast reconstruction after mastectomy.

Disparities in Access to Postmastectomy Breast Reconstruction: Does Living in a Specific ZIP Code Determine the Patient's Reconstructive Journey?

BACKGROUND

Postmastectomy breast reconstruction (BR) has been shown to provide long-term quality of life and psychosocial benefits. Despite the policies initiated to improve access to BR, its delivery continues to be inequitable, suggesting that barriers to access have not been fully identified and/or addressed. The purpose of this study was to assess the influence of geographic location, socioeconomic status, and race in access to immediate BR (IBR).

METHODS

An institutional review board-approved observational study was conducted. All patients who underwent breast cancer surgery from 2014 to 2019 were queried from our institutional Breast Cancer Registry. A geographical analysis was conducted using demographic characteristics and patient's ZIP codes. Euclidean distance from patient home ZIP code to UPMC Magee Women's Hospital was calculated, and χ2, Student t test, Mann-Whitney, and Kruskal-Wallis tests was used to evaluate differences between groups, as appropriate. Statistical significance was set at P < 0.05.

RESULTS

Overall, 5835 patients underwent breast cancer surgery. A total of 56.7% underwent lumpectomy or segmental mastectomy, and 43.3% underwent modified, total, or radical mastectomy. From the latter group, 33.5% patients pursued BR at the time of mastectomy: 28.6% autologous, 48.1% implant-based, 19.4% a combination of autologous and implant-based, and 3.9% unspecified reconstruction. Rates of IBR varied among races: White or European (34.1%), Black or African American (27.7%), and other races (17.8%), P = 0.022. However, no difference was found between type of BR among races (P = 0.38). Moreover, patients who underwent IBR were significantly younger than those who did not pursue reconstruction (P < 0.0001). Patients who underwent reconstruction resided in ZIP codes that had approximately US $2000 more annual income, a higher percentage of White population (8% vs 11% non-White) and lower percentage of Black or African American population (1.8% vs 2.9%) than the patients who did not undergo reconstruction.

CONCLUSIONS

While the use of postmastectomy BR has been steadily rising in the United States, racial and socioeconomic status disparities persist. Further efforts are needed to reduce this gap and expand the benefits of IBR to the entire population without distinction.

Defining the Ideal Breast Reconstruction Procedure After Mastectomy From the Patient Perspective: A Retrospective Analysis

Background:

An increasing number of breast cancer patients undergo immediate or secondary breast reconstruction, but the ideal method in terms of patient satisfaction remains ambiguous. We compared the 3 most common breast reconstruction techniques to determine patient satisfaction and objective outcomes.

Methods:

Retrospective study of 184 patients with breast cancer who underwent a reconstructive procedure between 1993 and 2011 at our institution. Procedures evaluated were implant-based reconstruction (IBR) alone, latissimus dorsi (LD) flap reconstruction with/without implant, and deep inferior epigastric perforator (DIEP) free flap reconstruction. A retrospective patient satisfaction questionnaire was sent to all women. Twenty patients from each subgroup were matched to conduct a standardized objective assessment of the sensitivity of their reconstructed breast. A blinded photographic evaluation was also performed by 3 independent observers to assess the esthetic aspect and symmetry.

Results:

DIEP obtained significantly higher average scores regarding the esthetic outcome, immediate reconstruction impact, and overall score in the questionnaire evaluation. The IBR had the best results in the somatosensory evaluation, with DIEP scoring better than LD. DIEP received higher scores on average than LD for the criteria of size and symmetry in the esthetic evaluation. No statistically significant differences were observed between IBR and DIEP.

Conclusions:

Good results were reported overall for all breast reconstruction procedures, with more reserved scores for LD. The DIEP reconstruction appeared to be the most satisfactory and best experienced reconstruction method for patients, despite the complexity of the intervention. Clinicians should be encouraged to consider DIEP as the principal choice for breast reconstruction.

Patient Perceptions and Determinants of Choice for Breast Reconstruction after Mastectomy among Saudi Patients

Background:

Undergoing mastectomy is often associated with a negative impact on the mental well-being of patients. Patients who undergo postmastectomy breast reconstruction (BR) have a better self-image and higher self-esteem. Many patients with breast cancer (BC) are unaware of the availability of BR options. This study aimed to assess BC patient perceptions and identify the determinants of patient choices to undergo BR after mastectomy.

Methods:

This study was conducted between May 10, 2019 and February 29, 2020 via an interview-based questionnaire, among BC patients at King Abdul Aziz University Hospital, Jeddah, Saudi Arabia. Ethical approval was obtained from the research ethics committee before the data collection.

Results:

Altogether, 400 patients (an overall 82% response rate) were included, of whom 155 (38.75%) were group 1 (willing to undergo BR). The mean age for group 1 was 46.04 ± 8.79, which was younger than for group 2 (unwilling to undergo BR) (P < 0.001). Furthermore, 117 (75.5%) of group 1 had no history of any chronic illness compared with 145 (59.2%) of group 2 (P < 0.001). Group 1 had more knowledge about BR (69.7%, P < 0.001), and the main reason to undergo BR was to regain femininity (26.8%). The remaining patients (31.3%) were unwilling to undergo BR in order to avoid additional surgery.

Conclusions:

The lack of knowledge and misconception about BR is one factor preventing BC patients from undergoing BR. Spreading awareness and providing accurate information regarding the procedure will allow women with BC to overcome postmastectomy fear.

Immediate breast reconstruction in locally advanced breast cancer: is it safe?

PURPOSE

Immediate breast reconstruction (IBR) following mastectomy remains controversial for locally advanced breast cancer over concerns regarding recurrence and complications which may delay adjuvant therapies. This study aimed to compare the oncologic outcomes and surgical safety of IBR following mastectomy with mastectomy alone (MA) for locally advanced breast cancer.

METHODS

All patients treated at the Providence Breast Center between 2012 and 2017 for biopsy-proven locally advanced breast cancer, AJCC (8th edition) clinical stages (IIB-IIIC), were included. Primary outcomes were overall survival (OS), disease-specific survival (DSS), and disease-free survival (DFS). Secondary outcomes included recurrence rate, adjuvant therapy use, and reoperation.

RESULTS

267 patients (112 IBR, 155 MA) were included. On average, IBR patients were younger (48.82 years vs 61.42 years, P < 0.001). Median study follow-up was 50.7 months. OS was higher among IBR patients (86.6% vs 73.5%, P < 0.05). However, no significant differences were found in DSS (87.5% vs 84.5%, P = 0.34), DFS (79.5% vs 78.7%, P = 0.55), local recurrence (0% vs 1.9%, P = 0.194), adjuvant therapy use (95.5% vs 91.6%, P = 0.155), or reoperation (1.8% vs 1.3%, P = 0.559).

CONCLUSION

IBR is a safe option for patients with locally advanced breast cancer and does not negatively impact survival, cancer recurrence rates, and use of adjuvant therapy.

Identifying the top research priorities in postmastectomy breast cancer reconstruction: a James Lind Alliance priority setting partnership

BACKGROUND

Major improvements in breast cancer treatment in the last decade include advancements in postmastectomy breast reconstruction (PMBR). Unfortunately, the studies in PMBR are primarily researcher or industry led with minimal input from patients and caregivers. The aim of this study is to use the James Lind Alliance (JLA) approach to bring together the patients, caregivers and clinicians in a priority setting partnership to identify the most important unanswered research questions in PMBR.

METHODS

The JLA priority setting methodology involved four key stages: gathering research questions on PMBR from patients, caregivers and clinicians; checking these research questions against existing evidence; interim prioritisation and a final consensus meeting to determine the top 10 unanswered research questions using the modified nominal group methodology.

RESULTS

In stage 1, 3168 research questions were submitted from 713 respondents across Canada, of which 73% of the participants were patients or caregivers. Stage 2 confirmed that there were a total of 48 unique unanswered questions. In stage three, 488 individuals completed the interim prioritisation survey and the top 25 questions were taken to a final consensus meeting. In the final stage, the top 10 unanswered research questions were determined. They cover a breadth of topics including personalised surgical treatment, safety of implants and newer techniques, access to PMBR, breast cancer recurrence and rehabilitation.

INTERPRETATION

Identification of the top 10 unanswered research questions is an important first step to generating relevant and impactful research that will ultimately improve the PMBR experience for patients with breast cancer.

Dissatisfaction After Post-Mastectomy Breast Reconstruction: A Mixed-Methods Study

BACKGROUND

Breast reconstruction is associated with improved patient well-being after mastectomy; however, factors that contribute to post-surgical dissatisfaction remain poorly characterized.

METHODS

Adult women who underwent post-mastectomy implant-based or autologous breast reconstruction between 2015 and 2019 were recruited to participate in semi-structured interviews regarding their lived experiences with reconstructive care. Participants completed the BREAST-Q, and tabulated scores were used to dichotomize patient-reported outcomes as satisfied or dissatisfied (high or low) for each BREAST-Q domain. A convergent mixed-methods analysis was used to evaluate interviews for content related to satisfaction or dissatisfaction with breast reconstruction.

RESULTS

Overall, we interviewed 21 women and identified 17 subcodes that corresponded with the five BREAST-Q domains. Sources of dissatisfaction were found to be related to the following domains: (a) low breast satisfaction due to asymmetry, cup size, and lack of sensation and physical feeling (n = 8, 38%); (b) poor sexual well-being due to shape, look and feel (n = 7, 78% [of 9 who discussed sexual well-being]); (c) reduced physical well-being of the chest due to persistent pain and weakness (n = 11, 52%); (d) reduced abdominal well-being due to changes in abdominal strength, numbness, and posture (n = 6, 38% [of 16 who underwent abdominally based reconstruction]); and (e) low psychosocial well-being impacted by an unexpected appearance that negatively influenced self-confidence and self-identity (n = 13, 62%).

CONCLUSION

Patients may be unprepared for the physical, sexual, and psychosocial outcomes of breast reconstruction. Targeted strategies to improve preoperative education and shared decision making are needed to mitigate unexpectedness associated with breast reconstruction and related outcomes.

Survival in breast cancer patients with a delayed DIEP flap breast reconstruction after adjustment for socioeconomic status and comorbidity

Purpose

Overall survival in breast cancer patients receiving a delayed deep inferior epigastric perforator (DIEP) flap breast reconstruction is better than in those without delayed breast reconstruction. This study aimed at determining the impact of socioeconomic status (SES) and comorbidity on these observations.

Materials and methods

This matched cohort study included all consecutive women undergoing a delayed DIEP flap reconstruction at Karolinska University Hospital, Sweden, between 1999 and 2013. Controls had not received any delayed breast reconstruction and were relapse-free after a corresponding follow-up interval. Matching was by year of and age at mastectomy, tumour stage and lymph node status. Charlson Comorbidity Index (CCI) and socioeconomic data were obtained from national registers. Associations with breast cancer-specific (BCSS) and overall survival (OS) were investigated by Kaplan-Meier survival estimates and Cox proportional hazard regression analysis.

Results

Women in the DIEP group (N = 254) more often continued education after primary school (88.6% versus 82.6%, P = 0.026), belonged to the high-income group (76.0% versus 63.1%, P < 0.001), were in a partnership (57.1% versus 55.7%, P = 0.024) and healthier (median CCI 1.00 (range 0–13) versus 2.00 (range 0–16), P = 0.021) than the control group (N = 729). After adjustment for tumour and treatment factors, SES and comorbidity, OS remained significantly better for the DIEP group than the control group (HR 2.27, 95% CI 1.44–3.55).

Conclusion

Women with a delayed DIEP flap reconstruction are a subgroup of higher socioeconomic status and better health. Higher survival estimates for the DIEP group persisted after adjusting for those differences, suggesting the presence of further unmeasured covariates.

•

Women with a delayed DIEP flap reconstruction have a higher socioeconomic status.

•

They also have less comorbidity than women with no delayed reconstruction.

•

Superior survival in DIEP patients is not eliminated by adjustments for such differences.

•

Unmeasured selection to the reconstructive process may explain observed survival differences.

Population-based picture of breast reconstruction in Queensland, Australia

BACKGROUND

Approximately 40% of women with invasive breast cancer will undergo a mastectomy. Clinical practice guidelines recommend breast reconstruction (BR) options should be discussed with all women who are to undergo a mastectomy. We sought to examine rates of BR, BR methods over time and to identify factors associated with the likelihood of receiving BR in Queensland.

METHODS

This population-based study used linked data from the Queensland Oncology Repository for 12 364 women who underwent a mastectomy for invasive breast cancer from 2008 to 2017. Multivariate logistic regression was used to model predictors of immediate breast reconstruction (IBR) and delayed breast reconstruction (DBR).

RESULTS

Overall, 2560 (20.7%) women had BR, with 9.8% having IBR and 10.9% having DBR. Factors associated with a reduced likelihood of IBR or DBR included older age (P < 0.001), living in a regional/rural area (P < 0.001) and having a mastectomy in a public versus private hospital (P < 0.001). Median time from mastectomy to DBR was 18.4 and 29.2 months for women attending a private versus public hospital, respectively (P < 0.001). Use of implant-based BR increased significantly with a corresponding decrease in autologous BR over time.

CONCLUSIONS

Significant disparities exist in rates of BR between public and private hospitals. Women living in regional and rural areas as well as those aged over 60 years continue to have lower rates of BR. Addressing the health system barriers and developing strategies to improve access to, and uptake of BR should be a priority.

Early Postoperative Complications From National Surgical Quality Improvement Program: A Closer Examination of Timing and Technique of Breast Reconstruction

BACKGROUND

Despite the recent surge in rates of immediate breast reconstruction, there is a paucity of large multicenter studies to compare differences in morbidity after immediate versus delayed breast reconstruction. This study used the National Surgical Quality Improvement Program (NSQIP) to study the association between timing of breast reconstruction and complication rates, stratified by reconstructive modality.

STUDY DESIGN

The NSQIP database was used to identify breast reconstructions from 2005 to 2012. Rates of major complications were compared by timing within each reconstructive modality (implant vs autologous). Cohort differences in baseline characteristics and variables associated with increased complication rates were identified in bivariate analyses. A multivariable model was created to compare the association between the timing of reconstruction and major complications.

RESULTS

Of 24,506 postmastectomy reconstructions, 85.8% were immediate, 14.2% were delayed, 84% were implant, and 16% were autologous reconstructions. Overall, 10.0% of patients suffered a major complication. After stratification, only implant reconstructions showed a statistically higher complication rate with immediate (8.8%) reconstruction compared with delayed (5.3%) (odds ratio, 1.7, P < 0.01). There was no significant difference in complication rates between autologous immediate (18.4%) or delayed (19.0%) reconstructions. After controlling for baseline cohort differences and other risk factors, immediate reconstruction remained as an independent significant predictor of major complications in implant reconstructions (odds ratio, 1.8, P < 0.01).

CONCLUSIONS

Immediate rather than delayed breast reconstruction is associated with a significantly higher rate of major complications in implant reconstruction but not in autologous reconstruction. It is important to include these findings in the routine preoperative surgeon-patient discussion of reconstructive options.

Adipose tissue-derived stem cells in breast reconstruction: a brief review on biology and translation

Recent developments in adipose-derived stromal/stem cell (ADSC) biology provide new hopes for tissue engineering and regeneration medicine. Due to their pluripotent activity, paracrine activity, and immunomodulatory function, ADSCs have been widely administrated and exhibited significant therapeutic effects in the treatment for autoimmune disorders, neurodegenerative diseases, and ischemic conditions both in animals and human clinical trials. Cell-assisted lipotransfer (CAL) based on ADSCs has emerged as a promising cell therapy technology and significantly improved the fat graft retention. Initially applied for cosmetic breast and facial enhancement, CAL has found a potential use for breast reconstruction in breast cancer patients. However, more challenges emerge related to CAL including lack of a standardized surgical procedure, the controversy in the effectiveness of CAL, and the potential oncogenic risk of ADSCs in cancer patients. In this review, we summarized the latest research and intended to give an outline involving the biological characteristics of ADSCs as well as the preclinical and clinical application of ADSCs.

Concurrent Prophylactic Mastectomy, Immediate Reconstruction, and Salpingo-Oophorectomy in High-Risk Patients: A Case Series

Purpose

There are limited data on coordinated breast and gynecological risk-reduction surgery for high-risk patients in Canada. Therefore, this study aims to evaluate the patient demographics, surgical details, and outcomes of prophylactic mastectomy (PM) with immediate reconstruction and bilateral salpingo-oophorectomy (BSO) in high-risk patients.

Methods

We conducted a retrospective chart review at an academic center of patients who concurrently underwent PM with immediate reconstruction and laparoscopic BSO over a 7-year period (March 2010-February 2017) were identified.

Results

A total of 16 patients underwent PM with immediate reconstruction and concurrent BSO. The mean age at the time of surgery was 46.2 ± 6.6 years. Thirteen (81%) patients were carriers of the BRCA1 or BRCA2 mutation. Two patients had prophylactic surgical therapy for BRCA1 mutation and 14 (87.5%) patients had prior oncological treatment. The most common type of procedures performed were skin-sparing, nipple-sparing mastectomy (56.2%) and reconstruction with acellular dermal matrix and implants (43.8%). All patients underwent laparoscopic BSO. The average combined case time was 282.5 ± 81.3 minutes with an average postoperative hospital stay of 1.3 ± 0.5 days. Six (37.5%) patients presented with 30-day postoperative complications, with higher rates in the alloplastic group. There were no gynecological complications.

Conclusions

In conclusion, our results demonstrate that a combined multidisciplinary surgical approach did not increase length of stay or 30-day complication rates. Furthermore, concurrent risk-reducing strategies are an effective option for patients at high risk of breast or ovarian cancer.

Breast reconstruction patterns from a Swedish nation-wide survey

OBJECTIVES

The overall aim of the Swedish Breast Reconstruction Outcome Study was to investigate national long-term outcomes after mastectomy with or without breast reconstruction. The current report evaluates breast reconstruction (BR) patterns in Sweden over time.

MATERIALS AND METHODS

This is a cross-sectional, registry-based study where all women operated with mastectomy 2000, 2005, 2010 were identified (N = 5853). Geographical differences in type of BR were investigated using heatmaps. Distribution of continuous variables were compared using the Mann-Whitney U test, categorical variables were compared using the chi-square test.

RESULTS

Mean age at survey was 69 years (SD=±11.4) and response rate was 50%, responders were on average six years younger than the non-responders and had a more favourable tumor stage (both p < 0.01). Of the 2904 responders, 31% (895/2904) had received a BR: implant-based in 58% (516/895)autologous in 31% (281/895). BR was immediate in 20% (176/895) and delayed in 80% (719/895) women. Women with BR were on average one year older, more often had a normal BMI, reported to be married or had a partner, had a higher educational level and a higher annual income when compared to those without BR (all p < 0.001). The independent factors of not receiving BR were older age and given radiotherapy.

CONCLUSIONS

To our knowledge, this is the first national long-term follow-up study on women undergoing mastectomy with and without BR. Around 30% of the survey responders have had a BR with a significant geographical variation highlighting the importance of information, availability and standardisation of indications for BR.

How Ineffective Interprofessional Collaboration Affects Delivery of Breast Reconstruction to Breast Cancer Patients: A Qualitative Study

BACKGROUND

Despite the benefits of breast reconstruction (BR), health care professionals do not consistently integrate it as an option in the treatment of breast cancer patients. Interprofessional collaboration (IPC) amongst professionals may facilitate the elaboration of comprehensive oncological treatment plans. As the application of IPC in the delivery of BR has not yet been studied, we undertook a qualitative study to explore the perceptions of physicians and administrators on IPC in breast cancer care and how these impact BR delivery.

METHODS

Interviews were conducted with 30 participants (22 physicians and 8 administrators). Physician interviews focused on their personal beliefs and values regarding BR, while administrator interviews explored their institutional treatment regimens as well as the availability of a BR program. Our thematic analysis was informed by the Canadian Interprofessional Health Collaborative (CIHC) competency framework.

RESULTS

IPC challenges were thought by participants to affect the delivery of BR. At the physician level, a lack of role clarity as well as the absence of an explicitly established leader negatively influence collaboration in BR delivery. In addition, varying views on the usefulness of BR and on the role of plastic surgeons in breast oncological teams discourage positive collaboration, rendering the delivery of BR more difficult.

CONCLUSIONS

The delivery of BR is overall impaired due to a lack of effective IPC. IPC could be improved through clarifying physician roles, establishing clear leadership, and aligning viewpoints on quality oncological care in collaborative teams; ultimately, this may promote equitable BR delivery for breast cancer patients.

Determinants of receiving immediate breast reconstruction: An analysis of patient characteristics at a tertiary care center in the US

BACKGROUND

Breast reconstruction is an option for women undergoing mastectomy for breast cancer. Previous studies have reported underutilization of reconstructive surgery. This study aims to examine the role demographic, clinical and socio-economic factors may have on patients' decisions to undergo breast reconstruction.

METHODS

We analyzed data from our institutional database. Using multivariable and multinomial logistic regression, we compared breast cancer patients who had undergone mastectomy-only to those who had immediate breast reconstruction (overall and by type of reconstruction).

RESULTS

We analyzed data on 1459 women who underwent mastectomy during the period 2003-2015. Of these, 475 (32.6%) underwent mastectomy-only and 984 (67.4%) also underwent immediate breast reconstruction. After adjusting for potential confounders, older age (OR = 0.18, 95%CI:0.08-0.40), Asian race (OR = 0.29, 95%CI:0.19-0.45), bilateral mastectomy (OR = 0.71, 95%CI:0.56-0.90), and higher stage of disease (OR = 0.44, 95%CI:0.26-0.74) were independent risk factors for not receiving immediate breast reconstruction. Furthermore, patients with Medicare or Medicaid insurance were less likely than patients with private insurance to receive an autologous reconstruction. There was no evidence for changes over time in the way socio-demographic and clinical factors were related to receiving immediate breast reconstruction after mastectomy.

CONCLUSIONS

Clinical characteristics, sociodemographic factors like age, race and insurance coverage affect the decision for reconstructive surgery following mastectomy.

Extended Prophylactic Antibiotics for Mastectomy with Immediate Breast Reconstruction: A Meta-analysis

Supplemental Digital Content is available in the text.

Background:

The risk of surgical site infection (SSI) for breast surgery in patients without additional risk factors is low, below 5%. Evidence shows the risk of SSI is significantly elevated in patients undergoing immediate breast reconstruction (IBR). However, there is no consensus regarding the use of extended antibiotic prophylaxis. We aim to determine the effect of extended antibiotic prophylaxis on the incidence of SSI after IBR.

Methods:

PubMed and Scopus were searched by 2 independent reviewers. Data abstracted included types of study, basic characteristics, detailed antibiotic prophylaxis information, SSI event, and other secondary outcomes. We calculated the risk ratio (RR) and 95% confidence interval (CI) for each study and used a random-effects model to estimate the results. Study quality, bias, and heterogeneity were also analyzed.

Results:

A total of 11 studies (15,966 mastectomy procedures) were included. We found an overall 5.99% SSI rate in our population. Three studies comparing topical antibiotics with no topical antibiotics demonstrated statistical significance (RR = 0.26, 95% CI: 0.12–0.60, P = 0.001), whereas 8 studies comparing extended systemic antibiotics with standard of care found no statistical significance (RR = 0.80, 95% CI: 0.60–1.08, P = 0.13).

Conclusions:

In the setting of IBR following mastectomy, there is insufficient evidence for the use of extended prophylactic antibiotics to reduce SSI rates. Well-designed randomized controlled trials in patients undergoing IBR should be conducted to determine the appropriate regimen and/or duration of prophylactic antibiotics on SSI outcomes.

Breast implant-associated anaplastic large cell lymphoma: A comprehensive review

Breast implant-associated anaplastic large cell lymphoma (BIA-ALCL) is a recently recognized non-Hodgkin lymphoma of T-cell origin. Despite the low incidence of this new disease, the increasing use of breast implants for cosmetic or post-mastectomy reconstruction purposes places BIA-ALC as an emerging and compelling medical challenge. The real BIA-ALCL pathogenesis has not been fully uncovered so far, while different putative causal factors have been proposed. Breast implants with textured surfaces seem to be associated with nearly all cases of BIA-ALCL, while the real the risk of disease development has not been well estimated so far. Late onset, persistent seroma around breast implant represents the classical clinical presentation. Most of the BIA-ALCL patients presents with localized disease, which confers an excellent prognosis. Unlike other non-Hodgkin lymphomas, surgical excision of the mass has a key role in the treatment. For patients with advanced and disseminated diseases, the treatment did not differ from other types of T-cell lymphoma. For these reasons, BIA-ALCL represents an emerging disease which requires multidisciplinary team approach to well define diagnostic workup and treatment for each patient. This review article aims to summarize available data on BIA-ALCL. First, we will outline available data on BIA-ALCL epidemiology, pathogenesis, diagnostic work-up, and treatment. Second, we will point out the potential psychological implications as well as the risk of perception distortion for women with breast implants, especially for those with previous breast cancer. Lastly, we will summarize the current national recommendations regarding textured breast implants and discuss the diagnostic-therapeutic algorithm for BIA-ALCL management.

Inquiry and computer program Onko-Online: 25 years of clinical registry for breast cancer at the University Medical Centre Maribor

Background High-quality routine care data collected in the clinical registry play a significant role in improving the management of cancer patients. Clinical cancer registries record important data in the course of cancer diagnosis, treatment, follow-up and survival. Analyses of such comprehensive data pool make it possible to improve the quality of patients care and compare with other health care providers. Methods The first inquiry at the Department of Gynaecologic and Breast Oncology of the then General Hospital Maribor to follow breast cancer patients has been introduced in 1994. Based on our experience and new approaches in breast cancer treatment, the context of inquiry has been changed and extended to the present form, which served as a model for developing a relevant computer programme named Onko-Online in 2014. Results During the 25-year period, we collected data from about 3,600 breast cancer patients. The computer program Onko-Online allowed for quick and reliable collection, processing and analysis of 167 different data of breast cancer patients including general information, medical history, diagnostics, treatment, and follow-up. Conclusions The clinical registry for breast cancer Onko-Online provides data that help us to improve diagnostics and treatment of breast cancer patients, organize the daily practice and to compare the results of our treatment to the national and international standards. A limitation of the registry is the potentially incomplete or incorrect data input by different healthcare providers, involved in the treatment of breast cancer patients.

Oncological Risk in Autologous Stem Cell Donation for Novel Tissue-Engineering Approaches to Postmastectomy Breast Regeneration

Adipose tissue engineering using adipose-derived stem cells (ADSCs) has emerged as an opportunity to develop novel approaches to postmastectomy breast reconstruction with the potential for an autologous tissue source with a natural appearance and texture. As of yet, the role of ADSCs in breast cancer development and metastasis is not completely understood; therefore, we must consider the oncological safety of employing an autologous source of ADSCs for use in breast regeneration. This study investigated the regenerative properties of ADSCs isolated from breast cancer patients, including those who had received neoadjuvant chemotherapy, and noncancer controls. The ADSCs were characterised for several parameters central to tissue regeneration, including cell viability, proliferation, differentiation potential, and cytokine secretion. A stem cell population was isolated and confirmed by flow cytometry and multilineage differentiation. There was no difference in cell phenotype or surface antigen expression between ADSCs from different sources. Adipose-derived stem cells isolated from the breast of cancer patients exhibited reduced adipogenic differentiation potential compared with ADSCs from other sources. The greatest degree of adipogenic differentiation was observed in ADSCs isolated from the subcutaneous abdominal fat of noncancer controls. The proliferation rate of ADSCs isolated from the breast of cancer patients was increased compared with other sources; however, it was decreased in ADSCs isolated from breast cancer patients who had recently been treated with neoadjuvant chemotherapy. A number of cytokines were detected in the cell conditioned media of ADSCs from different sources, including matrix metalloproteinase-2 (MMP-2), which was detected at higher levels in the secretome of ADSCs from breast cancer patients compared with noncancer controls. This study provides important information relating to the suitability of ADSCs as an autologous cell source for adipose tissue engineering in postcancer reconstruction. Results indicate that while the surface phenotype does not differ, the differentiation capacity, proliferative rate, and secreted cytokine profile are affected by the presence or treatment of breast cancer. These findings support further investigation into the regenerative potential of these ADSCs, if they are to be considered in clinical reconstructive strategies.

Association Between Hospital Financial Distress and Immediate Breast Reconstruction Surgery After Mastectomy Among Women With Ductal Carcinoma In Situ

Importance

Hospital financial distress (HFD) is a state in which a hospital is at risk of closure because of its financial condition. Hospital financial distress may reduce the services a hospital can offer, particularly unprofitable ones. Few studies have assessed the association of HFD with quality of care.

Objective

To examine the association between HFD and receipt of immediate breast reconstruction surgery after mastectomy among women diagnosed with ductal carcinoma in situ (DCIS).

Design, Setting, and Participants

This retrospective cohort study assessed data from the Nationwide Inpatient Sample of 5760 women older than 18 years (mean [SD] age: 57.5 [13.2]) with DCIS who underwent mastectomy in 2008-2012 at hospitals categorized by financial distress. Women treated at 1156 hospitals located in 538 different counties across Arkansas, Arizona, California, Colorado, Connecticut, Florida, Iowa, Kentucky, Massachusetts, Maryland, Missouri, North Carolina, New Hampshire, New Jersey, Nevada, New York, Oregon, Pennsylvania, Rhode Island, Utah, Virginia, Vermont, Washington, Wisconsin, West Virginia, and Wyoming were included. Of these, 2385 women (41.4%) underwent immediate breast reconstruction surgery. Women with invasive cancer were excluded. The database included unique hospital identification variables, and participants were identified using International Classification of Diseases, Ninth Revision, Clinical Modification codes. Data were analyzed from January 1, 2012, to February 28, 2014.

Main Outcomes and Measures

The primary outcome was the adjusted association between HFD and receipt of immediate breast reconstruction surgery after mastectomy.

Results

In this analysis of database information, 2385 of 5760 women (41.4%) received immediate breast reconstruction surgery. Of these, 693 (36.7%) were treated at a hospital under high HFD and received immediate breast reconstruction surgery compared with 863 (44.0%) treated at a hospital under low HFD (P < .001). Reconstruction surgery was associated with younger age, white race, private insurance, treatment at a teaching and cancer hospital, private hospital ownership, and the percentage of individuals in the county with insurance. After adjustment, women treated at hospitals under high HFD (OR, 0.79; 95% CI, 0.62-0.99) and medium HFD (OR, 0.76; 95% CI, 0.61-0.94) were significantly less likely to receive reconstruction than women treated at hospitals with low to no HFD.

Conclusions and Relevance

The financial strength of the hospital where a patient receives treatment is associated with receipt of immediate breast reconstruction surgery. In addition to focusing on patient-related factors, efforts to improve quality should also focus on hospital-related factors.

How patient acceptability affects access to breast reconstruction: a qualitative study

OBJECTIVES

There has been limited research on the acceptability of breast reconstruction (BR) to breast cancer patients. We performed interviews to explore breast cancer patients' acceptability of BR.

DESIGN

Qualitative study.

SETTING

Recruitment from six Ontario hospitals across the province (Toronto, Ottawa, Hamilton, London, Thunder Bay and Windsor) as well as key breast cancer organisations between November 2017 and June 2018.

PARTICIPANTS

Women of any age with a diagnosis of breast cancer planning to undergo or having undergone a mastectomy with or without BR.

INTERVENTION

Sixty-minute semi-structured interviews were analysed using qualitative descriptive methodology that draws on inductive thematic analysis.

OUTCOME

In the telephone interviews, participants discussed their experience with breast cancer and accessing BR, focusing on the acceptability of BR as a surgical option post-mastectomy.

RESULTS

Of the 28 participants, 11 had undergone BR at the time of the interview, 5 at the time of mastectomy and 6 at a later date. Four inter-related themes were identified that reflected women's evolving ideas about BR as they progressed through different stages of their disease and treatment. The themes we developed were: (1) cancer survival before BR, (2) the influence of physicians on BR acceptability, (3) patient's shift to BR acceptance and (4) women's need to justify BR. For many women, access to BR surgery became more salient over time, thus adding a temporal element to the existing access framework.

CONCLUSION

In our study, women's access to BR was negatively influenced by the poor acceptability of this surgical procedure. The acceptability of BR was a complex process taking place over time, from the moment of breast cancer diagnosis to BR consideration. BR access may be improved through enhancing patient acceptability of BR. We suggest adapting the current access to care frameworks by further developing the concept of acceptability.

Barriers of Access to Breast Reconstruction: A Systematic Review

BACKGROUND

The purpose of this systematic review was to comprehensively summarize barriers of access to breast reconstruction and evaluate access using the Penchansky and Thomas conceptual framework based on the six dimensions of access to care.

METHODS

The authors performed a systematic review that focused on (1) breast reconstruction, (2) barriers, and (3) breast cancer. Eight databases (i.e., EMBASE, MEDLINE, PsycINFO, CINHAL, ePub MEDLINE, ProQuest, Cochrane Database of Systematic Reviews, and Cochrane Central Register of Controlled Trials) were searched. English peer-reviewed articles published between 1996 and 2016 were included.

RESULTS

The authors' search retrieved 4282 unique articles. Two independent reviewers screened texts, selecting 99 articles for inclusion. All studies were observational and qualitative in nature. The availability of breast reconstruction was highest in teaching hospitals, private hospitals, and national cancer institutions. Accessibility affected access, with lower likelihood of breast reconstruction in rural geographic locations. Affordability also impacted access; high costs of the procedure or poor reimbursement by insurance companies negatively influenced access to breast reconstruction. Acceptability of the procedure was not universal, with unfavorable physician attitudes toward breast reconstruction and specific patient and tumor characteristics correlating with lower rates of breast reconstruction. Lastly, lack of patient awareness of breast reconstruction reduced the receipt of breast reconstruction.

CONCLUSIONS

Using the access-to-care framework by Penchansky and Thomas, the authors found that barriers to breast reconstruction existed in all six domains and interplayed at many levels. The authors' systematic review analyzed this complex relationship and suggested multiprong interventions aimed at targeting breast reconstruction barriers, with the goal of promoting equitable access to breast reconstruction for all breast cancer patients.

Body mass index impacts infection rates in immediate autogenous breast reconstruction

PURPOSE

Risk of postoperative infection following breast cancer reconstruction warrants consideration of both classic and procedure-specific risk factors. We performed a retrospective chart review of patients with breast cancer over a 10-year period that underwent reconstructive surgery to identify factors that increase risk of postoperative infection.

METHODS

Rates of postoperative infection were assessed in primary (immediate or delayed, alloplastic or autogenous) and secondary reconstructive procedures. Patient characteristics, surgical details, and cancer features were analyzed using two-sample t test and Fisher's exact test for continuous and categorical data, respectively.

RESULTS

456 procedures were performed on 264 patients with 29 cases of postoperative infection (6%). Infection was more likely to occur in earlier reconstructive procedures (p < 0.03). Overall, primary reconstructive procedures were associated with a higher infection rate (p = 0.005). Other associated risk factors included: autogenous reconstruction (p < 0.018), length of admission (p < 0.001) and immediate reconstruction (p = 0.01). Subgroup analysis revealed increased risk of infection with immediate autogenous reconstruction (p < 0.03). Furthermore, patients with greater body mass index (BMI) receiving immediate autogenous reconstruction had a greater risk of infection (p < 0.003). Factors unrelated to risk of infection included history of irradiation, smoking, cancer stage, tumor type and tumor size.

CONCLUSIONS

Our findings suggest that risk of infection is higher in immediate autogenous reconstructions particularly when patients are overweight (BMI > 30). Our data do not support a relationship between infection and irradiation, features of cancer, or repeated reconstructive procedures. Prospective studies may be required to further validate these findings.

Feasibility of Implementing a Breast Reconstruction Database

Objective

To assess whether implementing a breast reconstruction database would be feasible in terms of time commitment, cost, and overall benefits in a tertiary-care hospital.

Methods

A survey was sent to 40 Canadian plastic surgeons who have a practice focused on breast reconstruction. The survey assessed demographics, practice characteristics, database use, and opinions on database construction. Univariate descriptive analyses were performed on all variables.

Results

Thirty-one surgeons responded to the survey (77.5%). Most were from Ontario (29.1%) and worked in an academic center (83.9%). Of all, 45.3% of surgeons performed more than 50 breast reconstructions yearly. Six (19.4%) surgeons utilized databases that were all started for quality improvement and research purposes. Databases included variables such as demographics, type of reconstruction, complications, surgeons involved, and type of implants. Data are input by research assistants (50%) for approximately 4.2 hours per month at a cost below 200$CAD per month. Databases are funded by research grants (50%), hospital funds (33.3%), and/or division funds (16.7%). Of the surgeons without databases, 60% have considered starting a database. Barriers include being too busy (72%) and impressions of the cost being too high (32%). Surgeons commonly felt that a database would be beneficial at their practice (80%), provincially (77.4%), and nationally (67.7%).

Conclusions

Plastic surgeons are open to the idea of constructing a breast reconstruction database and that the costs and time required are lower than expected. Grants or integration with existing databases should be pursued on a provincial level first prior to pursuing a national database.

Optimise not compromise: The importance of a multidisciplinary breast cancer patient pathway in the era of oncoplastic and reconstructive surgery

Modern breast cancer care is a complex multidisciplinary undertaking in which the integrated function of multiple constituent parts is critical, and where changes to one therapeutic component may profoundly influence the delivery and outcomes of another. Oncoplastic and reconstructive breast surgery has evolved in the era of longer survival rates for women with breast cancer and aims to enhance oncological and cosmetic outcomes. However, concurrently there has been an expansion in the indications for post-mastectomy radiation therapy (Abdulkarim et al., 2011; Early Breast Cancer Trialists' Collaborative Group (EBCTCG), 2014; Poortmans et al., 2015; Wang et al., 2011), the recognition of several biologically distinct breast cancer subtypes (Perou et al., 2000; Sørlie et al., 2001, 2003; Cheang et al., 2008, 2009; Sotiriou et al., 2003; Millar et al., 2011; Blows et al., 2010; Schnitt, 2010; Haque et al., 2012; Dai et al., 2015) and the development of recommendations for prophylactic surgery for high-risk women, including BRCA-mutation carriers (James et al., 2006; Domchek et al., 2010). Primary systemic therapy is increasingly utilised yet has varying efficacy depending on tumour biology (Cortazar et al., 2014). In this paper we review the evidence which informs the multidisciplinary team opinion in the era of oncoplastic and reconstructive breast surgery. We aim to describe an optimal multidisciplinary approach which balances competing risks of multimodal therapies to optimise oncological and cosmetic outcomes.

Hydrogels in adipose tissue engineering-Potential application in post-mastectomy breast regeneration

Current methods of breast reconstruction are associated with significant shortcomings, including capsular contracture, infection, rupture, the need for reoperation in implant-based reconstruction, and donor site morbidity in autologous reconstruction. These limitations result in severe physical and psychological issues for breast cancer patients. Recently, research has moved into the field of adipose tissue engineering to overcome these limitations. A wide range of regenerative strategies has been devised utilising various scaffold designs and biomaterials. A scaffold capable of providing appropriate biochemical and biomechanical cues for adipogenesis is required. Hydrogels have been widely studied for their suitability for adipose tissue regeneration and are advantageous secondary to their ability to accurately imitate the native extracellular matrix. The aim of this review was to analyse the use of hydrogel scaffolds in the field of adipose tissue engineering.

Understanding patient choices regarding breast reconstruction after mastectomy for breast cancer

PURPOSE

In Australia, about 40% of patients undergo mastectomy to treat breast cancer, with negative impacts on body image, sexual function and quality of life. Whilst breast reconstruction is associated with increased patient self-esteem and a greater sense of wholeness and well-being, the national reconstruction rate is low at 18%. This study aimed to compare demographics, treatment factors and information provision about breast reconstruction in women who had and did not have breast reconstruction following mastectomy treatment and identify goals and concerns underpinning women's reconstruction decisions.

METHODS

Female patients who had a mastectomy to treat breast cancer between 2010 and 2014 in a culturally and linguistically diverse (CALD) and socially disadvantaged region participated in a cross-sectional study, completing a questionnaire in their language of choice (English, Vietnamese, Chinese or Arabic).

RESULTS

Completed surveys were returned by 168 women (42% response rate; 77% English-speaking), of whom only 19.0% (n = 32) reported having had breast reconstruction. Reconstruction rates were significantly lower in women who reported speaking a language other than English at home versus only English (37.5% vs 62.5%, p = 0.03). However, all women expressed a desire for more information about breast reconstruction and more support to make their decision about breast reconstruction.

CONCLUSIONS

Patients identified a need for greater information provision on breast reconstruction, highlighting an urgent need for resources specifically about breast reconstruction, particularly for non-English-speaking patients. Greater provision of information prior to mastectomy is critical to underpin breast cancer patients' decisions about breast reconstruction, especially for non-English speaking patients.

Objectif

Présenter aux prestataires de soins primaires un résumé complet des options en matière de reconstruction mammaire et de leurs complications.

Sources de l’information

Une recherche documentaire a été effectuée dans PubMed, sans restrictions relatives à la date de publication, à l’aide des expressions de recherche en anglais breast reconstruction, summary, review, complications et options. Les niveaux des données probantes varient de I à III.

Message principal

Étant donné la hausse des taux de survie au cancer du sein, la prise en charge doit changer de cap pour inclure aussi la restauration de la qualité de vie de la patiente après le cancer. La reconstruction mammaire joue un rôle majeur pour un retour à la normale chez ces femmes. Les femmes qui subissent une mastectomie éprouvent souvent des difficultés quant à leur image corporelle et à leur estime de soi, et elles évaluent leur qualité de vie à la baisse. La carte des voies pathologiques d’Action Cancer Ontario préconise que toutes les femmes ayant reçu un diagnostic de cancer du sein qui pourraient avoir besoin d’une mastectomie soient envoyées en consultation en chirurgie plastique pour discuter des options de reconstruction avant l’opération.

Conclusion

Les connaissances et les conseils des médecins de soins primaires sont essentiels pour bien orienter et appuyer les patientes dans leur processus décisionnel quant à la reconstruction mammaire. Il est nécessaire de bien comprendre les facteurs de sélection des patientes, les options contemporaines de reconstruction mammaire et les résultats attendus.

Breast reconstruction: Updated overview for primary care physicians

OBJECTIVE

To offer primary care providers a comprehensive summary of breast reconstruction options and complications.

QUALITY OF EVIDENCE

A literature search was conducted in PubMed with no time restriction using the search terms breast reconstruction, summary, review, complications, and options. Levels of evidence range from I to III.

MAIN MESSAGE

As breast cancer survival rates increase, the focus of breast cancer management must shift to include the restoration of a patient's quality of life after cancer. Breast reconstruction plays a crucial role in the restoration of normality for these women. Women who undergo mastectomy often suffer from challenges related to body image, self-esteem, and a decrease in quality of life scores. Cancer Care Ontario's Breast Cancer Treatment Pathway Map mandates that all women diagnosed with breast cancer who might require mastectomy be referred to a plastic surgeon to discuss reconstructive options before surgery.

CONCLUSION

The knowledge and guidance of primary care providers is critical to effectively guiding and supporting patients who might undergo breast reconstruction in their decision-making processes. A thorough understanding of patient selection factors, modern options for breast reconstruction, and expected outcomes is essential.

Risk of recurrence and death in patients with breast cancer after delayed deep inferior epigastric perforator flap reconstruction

Background

Postmastectomy reconstruction using a deep inferior epigastric perforator (DIEP) flap is increasingly being performed in patients with breast cancer. The procedure induces extensive tissue trauma, and it has been hypothesized that the release of growth factors, angiogenic agonists and immunomodulating factors may reactivate dormant micrometastasis. The aim of the present study was to estimate the risk of breast cancer recurrence in patients undergoing DIEP flap reconstruction compared with that in patients treated with mastectomy alone.

Methods

Each patient who underwent delayed DIEP flap reconstruction at Karolinska University Hospital, Sweden, between 1999 and 2013, was compared with up to four controls with breast cancer who did not receive a DIEP flap. The control patients were selected using incidence density matching with respect to age, tumour and nodal status, neoadjuvant therapy and year of mastectomy. The primary endpoint was breast cancer‐specific survival. Survival analysis was carried out using Kaplan–Meier survival estimates and Cox proportional hazard regression analysis.

Results

The analysis included 250 patients who had 254 DIEP flap reconstructions and 729 control patients. Median follow‐up was 89 and 75 months respectively (P = 0·053). Breast cancer recurrence developed in 50 patients (19·7 per cent) in the DIEP group and 174 (23·9 per cent) in the control group (P = 0·171). The 5‐year breast cancer‐specific survival rate was 92·0 per cent for patients with a DIEP flap and 87·9 per cent in controls (P = 0·032). Corresponding values for 5‐year overall survival were 91·6 and 84·7 per cent (P < 0·001). After adjustment for tumour and patient characteristics and treatment, patients without DIEP flap reconstruction had significantly lower overall but not breast cancer‐specific survival.

Conclusion

The present findings do not support the hypothesis that patients with breast cancer undergoing DIEP flap reconstruction have a higher rate of breast cancer recurrence than those who have mastectomy alone.

A Qualitative Assessment of the Journey to Delayed Breast Reconstruction

BACKGROUND

Canada has low immediate breast reconstruction (IBR) rates compared to the United States and Europe. Breast cancer survivors live with mastectomy defects sometimes for years, and this represents an area for improvement in cancer care.

PURPOSE

This study qualitatively assessed (1) information provided about breast reconstruction at the time of cancer diagnosis among women seeking delayed breast reconstruction (DBR) and (2) referral practices for plastic surgery consultation for DBR.

METHODS

Fifty-two consecutive patients seen in consultation for DBR at a single Canadian tertiary care centre completed questionnaires regarding their experience in seeking breast reconstruction. Seven semi-structured interviews were conducted to further explore themes identified through questionnaires. Questionnaire responses and interview transcripts were analyzed for recurring themes using standard qualitative techniques.

RESULTS

A significant portion of women (43%) was interested in reconstruction prior to mastectomy, yet IBR was infrequently discussed (14%) or discouraged by their oncologic surgeons (33%). Common patient reasons for not pursuing IBR were referring physician objection and not having adequate knowledge. Women expressed wanting to discuss reconstruction at the time of cancer diagnosis. Half of the patients had attended another consultation, but the initial plastic surgeon either did not offer procedures for which these women were candidates or had prohibitively long surgical wait times.

CONCLUSION

Lack of information about reconstructive options at the time of cancer diagnosis and perceived access barriers to plastic surgeons may contribute to underutilization of IBR in Canada. Access to breast reconstruction can be improved by reducing inefficiencies in plastic surgery referrals.

The Relationship Between Geographic Access to Plastic Surgeons and Breast Reconstruction Rates Among Women Undergoing Mastectomy for Cancer

INTRODUCTION

Despite a national health care policy requiring payers to cover breast reconstruction, rates of postmastectomy reconstruction are low, particularly among minority populations. We conducted this study to determine if geographic access to a plastic surgeon impacts breast reconstruction rates.

METHODS

Using 2010 inpatient and ambulatory surgery data from 10 states, we identified adult women who underwent mastectomy for breast cancer. Data were aggregated to the health service area (HSA) level and hierarchical generalized linear models were used to risk-standardize breast reconstruction rates (RSRR) across HSAs. The relationship between an HSA's RSRR and plastic surgeon density (surgeons/100,000 population) was quantified using correlation coefficients.

RESULTS

The final cohort included 22,997 patients across 134 HSAs. There was substantial variation in plastic surgeon density (median, 1.4 surgeons/100,000; interquartile range, [0.0-2.6]/100,000) and the use of breast reconstruction (median RSRR, 43.0%; interquartile range, [29.9%-62.8%]) across HSAs. Higher plastic surgeon density was positively correlated with breast reconstruction rates (correlation coefficient = 0.66, P < 0.001) and inversely related to time between mastectomy and reconstruction (correlation coefficient = -0.19, P < 0.001). Non-white and publicly insured women were least likely to undergo breast reconstruction overall. Among privately insured patients, racial disparities were noted in high surgeon density areas (white = 79.0% vs. non-white = 63.3%; P < 0.001) but not in low surgeon density areas (34.4% vs 36.5%; P = 0.70).

CONCLUSIONS

The lack of geographic access to a plastic surgeon serves as a barrier to breast reconstruction and may compound disparities in care associated with race and insurance status. Future efforts to improve equitable access should consider strategies to ensure access to appropriate clinical expertise.

Trends in breast reconstruction practices in a specialized breast tertiary referral centre

BACKGROUND

Breast reconstruction is an important component of multidisciplinary breast cancer management. The practice of breast reconstruction after mastectomy has evolved significantly in the past decade as a result of both increasing mastectomy rates and advances in reconstructive strategy. These changes have significantly influenced the contemporary surgical management of breast cancer. The aim of this study was to examine trends in breast reconstruction after mastectomy in an Irish population.

METHODS

Data were reviewed from a database of all patients who had mastectomy with or without breast reconstruction at Galway University Hospital, a tertiary breast cancer referral centre, between 2004 and 2014. Trends in breast reconstruction after mastectomy were explored with respect to patient demographics, clinicopathological features, and neoadjuvant and adjuvant therapy.

RESULTS

Of 1303 patients who underwent mastectomy during interval studied, 706 (54.2 per cent) had breast reconstruction after mastectomy. In 629 patients (89·1 per cent), breast reconstruction was performed in the immediate setting. Reconstruction rates increased over time from 20·5 per cent in 2004 to 44·7 per cent in 2014. Reconstruction was more commonly performed in younger patients and those with benign, in situ and early-stage disease. A negative relationship between radiotherapy and reconstruction was observed. A pedicled flap with or without an implant was the most commonly used reconstructive approach in patients receiving radiotherapy.

CONCLUSION

Breast reconstruction after mastectomy has become the standard of care in the surgical treatment of breast cancer. Recent trends show a transition favouring implant-based approaches.
