Socio-demographic, clinical, and health-related factors associated with breast reconstruction – A nationwide cohort study

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.

Study protocol for a 10-year prospective observational study, examining lymphoedema and patient-reported outcome after breast reconstruction

INTRODUCTION

Over the last decades, treatment of breast cancer has become increasingly more effective. Consequently, an increasing number of women are living with late effects of breast cancer treatment, including disfiguring scars, deformity or asymmetry of the breast, secondary lymphoedema and other physical and psychosocial late effects. Data from this study will provide knowledge on how to guide breast reconstruction in the future towards outcomes with fewer complications, higher long-term quality of life (QoL) and satisfaction with the aesthetic outcome. The development of secondary lymphoedema, for which the effect of breast reconstruction has yet to be established, will be thoroughly examined.

METHODS AND ANALYSIS

Women receiving breast reconstruction (autologous and implant based) at the Department of Plastic Surgery and Burns Treatment, Rigshospitalet, will be invited to participate. The patients will be followed for 10 years postoperatively. Demographic, health-related, oncological characteristics and treatment data will be registered. Validated assessment tools, such as the BREAST-Q and Beck Depression Inventory, will be used to measure an extensive range of clinical outcomes, including QoL, life and aesthetic satisfaction and depression. Arm range of motion will be measured with a goniometer and lymphoedema by bioimpedance spectroscopy, compared with circular arm measurements.

ETHICS AND DISSEMINATION

This study will be conducted according to the 5th version of the Helsinki Declaration. The regional ethical committee for Capital Region Denmark did not find the study notifiable, according to the law of the committee § 1, part 4. All data will be anonymised before its publication. This study will be conducted according to the Danish data protection regulation and is catalogued and approved by the Capital Region Head of Knowledge Centre. According to the Danish health law § 46, part 2, this study does not need the Danish Patient Safety Authority's approval. The findings of this study will be submitted to international peer-reviewed journals.

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.

Absence of residual fluorescence in the surgical bed at near-infrared fluorescence imaging predicts negative margins at final pathology in patients treated with breast-conserving surgery for breast cancer

INTRODUCTION

Positive margins after breast-conserving surgery (BCS) for breast cancer (BC) remain a major concern. In this study we investigate the feasibility and accuracy of indocyanine green (ICG) fluorescence imaging (FI) for the in vivo assessment of surgical margins during BCS.

MATERIALS AND METHODS

Patients with BC admitted for BCS from October 2015 to April 2016 were proposed to be included in the present study (NCT02027818). ICG (0.25 mg/kg) was intravenously injected at induction anesthesia and ICG-FI of the surgical beds was correlated with final pathology results.

RESULTS

Fifty patients consented to participate and thirty-five patients were retained for final analysis, 15 patients having been excluded for, respectively, incomplete video records data for signal to background ratio (SBR) calculation (11) and in situ tumors (4). The final pathological assessment of 35 breast specimens identified 5 (14.7%) positive margins. Intraoperative ICG-FI revealed hyperfluorescent signals in 15 (42.9%) patients and an absence of fluorescent signals in 20 (57.1%). Median SBR in patients with involved margins was 1.8 (SD 0.7) and was 1.25 (SD 0.6) in patients with clear margins (p = 0.05). The accuracy, specificity, positive and negative predictive value of ICG-FI for breast surgical margin assessment were 71%, 60%, 29% and 100%, respectively.

CONCLUSION

ICG-FI of BC surgical beds has a high negative predictive value for surgical margin assessment during BCS. The absence of residual fluorescence in the surgical bed of patients with fluorescent tumors predicts negative margins at final pathology and allows the surgeon to avoid further intraoperative analysis.

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.

Association of sociodemographic and oncological features with decision on implant-based versus autologous immediate postmastectomy breast reconstruction in Chinese patients

Background and objectives

Immediate postmastectomy breast reconstruction (IPBR) has gained wide popularity in China. We sought to clarify the prevalence and predictors of implant‐based vs autologous IPBR among Chinese patients.

Methods

A retrospective cohort study was performed using a prospectively maintained database. Women who underwent IPBR during 2001‐2017 were included. The modality‐specific trends were deciphered by curve fitting analysis. The association of sociodemographic and oncological features with the decision for implant‐based vs autologous IPBR was investigated using multivariate logistic regression and structural equation modeling.

Results

Among 905 patients included in the study, 479 underwent implant‐based IPBR and 426 underwent autologous procedures. The implant/autologous ratio has increased exponentially over time. Multivariate analysis demonstrated that unmarried patients with BMI ≤ 24 kg/m², earlier clinical tumor stage, and preoperative pathological diagnosis of noninvasive lesion are more likely to choose implant‐based IPBR compared to autologous procedures. The indirect effects of age, mastectomy type, and neoadjuvant chemotherapy were further demonstrated by the structural equations.

Conclusions

The sociodemographic and oncological features are directly or indirectly associated with the decision on type of IPBR. The findings may facilitate both patients and physicians to make a high‐quality decision by holistic evaluation of the sociodemographic and oncological features.

Understanding the effects of socioeconomic status along the breast cancer continuum in Australian women: a systematic review of evidence

Background

Globally, the provision of equitable outcomes for women with breast cancer is a priority for governments. However, there is growing evidence that a socioeconomic status (SES) gradient exists in outcomes across the breast cancer continuum – namely incidence, diagnosis, treatment, survival and mortality. This systematic review describes this evidence and, because of the importance of place in defining SES, findings are limited to the Australian experience.

Methods

An on-line search of PubMed and the Web of Science identified 44 studies published since 1995 which examined the influence of SES along the continuum. The critique of studies included the study design, the types and scales of SES variable measured, and the results in terms of direction and significance of the relationships found. To aid in the interpretation of results, the findings were discussed in the context of a systems dynamic feedback diagram.

Results

We found 67 findings which reported 107 relationships between SES within outcomes along the continuum. Results suggest no differences in the participation in screening by SES. Higher incidence was reported in women with higher SES whereas a negative association was reported between SES and diagnosis. Associations with treatment choice were specific to the treatment choice undertaken. Some evidence was found towards greater survival for women with higher SES, however, the evidence for a SES relationship with mortality was less conclusive.

Conclusions

In a universal health system such as that in Australia, evidence of an SES gradient exists, however, the strength and direction of this relationship varies along the continuum. This is a complex relationship and the heterogeneity in study design, the SES indicator selected and its representative scale further complicates our understanding of its influence. More complex multilevel studies are needed to better understand these relationships, the interactions between predictors and to reduce biases introduced by methodological issues.

Personality Traits as Predictors of Quality of Life and Body Image after Breast Reconstruction

Background:

It has been suggested that personality traits may influence patient-reported outcomes of breast reconstruction, but the research is limited. We investigated, in a prospective study, whether personality traits predict the achieved body image and quality of life (QoL) after breast reconstruction.

Methods:

Patients planning to undergo breast reconstruction at a University Hospital were consecutively recruited from January 2014 to January 2016. Participants completed validated measures of personality, body image, and QoL, before and 6 months after breast reconstruction. The influence of personality traits on achieved body image and QoL was explored with multivariate linear regression modelling, adjusting for baseline scores, demographics, and clinical variables.

Results:

Of 247 eligible patients, 208 (84%) participated. Twelve patients (6%) were excluded due to failed reconstruction. Of the remaining 196 patients, 180 (92%) completed the follow-up questionnaire. When adjusted for baseline QoL scores, higher trait Neuroticism, higher trait Openness, and higher body mass index measured at baseline showed to be independent and statistically significant predictors of deteriorating QoL scores from baseline to 6-month follow-up (P < 0.001; R² = 0.45). When adjusted for body image scores at baseline, higher trait Neuroticism and immediate reconstruction were found to be independent predictors of poorer body image from baseline to 6-months follow-up (P < 0.001; R² = 0.36).

Conclusions:

The present study suggests personality traits, in particular Neuroticism, as independent predictors of the achieved body image and QoL after breast reconstruction. Weighing in the personality traits of the patients may be an important adjunct in improving patient-reported outcomes after breast reconstructions.

Unilateral breast reconstruction after mastectomy - patient satisfaction, aesthetic outcome and quality of life

BACKGROUND

An increasing number of women undergo a breast reconstruction (BR) after treatment for breast cancer. The aim of the present study was to evaluate patient-reported esthetic satisfaction, quality of life (QoL), and the association between these, following different types of BR.

MATERIALS AND METHODS

All women who underwent unilateral BR in Central Denmark Region between January 2005 and July 2011 were included. Participants were sent a questionnaire package, which included the Body Image Scale, The Beck Depression Inventory, the Impact of Event Scale, and a study-specific patient-reported esthetic satisfaction scale. Additionally, patients were asked if they experienced a change in QoL owing to the BR. Based on reconstructive method and timing, participants were divided into four groups, three delayed: an abdominal flap group, a latissimus dorsi flap group, an implant ± thoracodorsal flap group; and one immediate BR group.

RESULTS

Of 166 eligible participants, a total of 144 women (87%) completed the questionnaire. The mean follow-up was 3.8 years. Esthetic satisfaction differed significantly between groups [F(3,139) = 8.55; p < 0.001], with abdominal flap recipients reporting the highest levels of esthetic satisfaction. No between-group differences were observed for the remaining psychosocial measures. Higher satisfaction with esthetic outcome was associated with reporting higher QoL owing to the BR (odds ratio 1.10, p<0.001; 95% CI 1.06-1.15).

CONCLUSIONS

Abdominal flap recipients expressed higher satisfaction with their esthetic outcome, compared to the remaining BR types. Higher esthetic satisfaction was strongly associated with reporting an experience of higher QoL.
