Racial disparities in postmastectomy breast reconstruction: National trends in utilization from 2005 to 2014

National trends and predictors of mastectomy with immediate breast reconstruction

PURPOSE

This study aimed to evaluate national trends in utilization, resource use, and predictors of immediate breast reconstruction (IR) after mastectomy.

METHODS

The 2005-2014 National Inpatient Sample database was used to identify adult women undergoing mastectomy. IR was defined as any reconstruction during the same inpatient stay. Multivariable regression models were utilized to identify factors associated with IR.

RESULTS

Of 729,340 patients undergoing mastectomy, 41.3% received IR. Rates of IR increased from 28.2% in 2005 to 58.2% in 2014 (NP-trend<0.001). Compared to mastectomy alone, IR was associated with increased length of stay (2.5 vs. 2.1 days, P < 0.001) and hospitalization costs ($17,628 vs. $8,643, P < 0.001), which increased over time (P < 0.001). Predictors of IR included younger age, fewer comorbidities, White race, private insurance, top income quartile, teaching hospital designation, high mastectomy volume, and performance of bilateral mastectomy.

CONCLUSION

Mastectomy with IR is increasingly performed with resource utilization rising at a steady pace. Our study points to persistent sociodemographic and hospital level disparities associated with the under-utilization of IR. Efforts are needed to alleviate disparities in IR.

Genomic expression assay testing among American Indian and Alaska Native women with breast cancer

BACKGROUND

Breast cancer is one of the most common causes of cancer mortality for all women, including American Indian and Alaska Native (AI/AN) women. The use of the 21-gene recurrence score (RS) appears to be predictive of the benefit of chemotherapy for women with estrogen receptor (ER)-positive breast cancer. The objective of the current study was to compare RS testing between AI/AN and non-Hispanic White (NHW) women with breast cancer.

METHODS

The Surveillance, Epidemiology, and End Results program was used to identify women with ER-positive breast cancer from 2004 through 2015. Multivariable logistic regression was used to evaluate factors associated with RS use, with high-risk RS, and with chemotherapy use among those with a high-risk RS.

RESULTS

A total of 363,387 NHW patients and 1951 AI/AN patients with ER-positive breast cancer were identified. AI/AN women were found to be less likely to undergo RS testing and, when tested, were more likely to have a high-risk RS. In the multivariable logistic regression analysis, AI/AN women were found to be significantly more likely to have a high-risk RS (odds ratio,1.28; 95% confidence interval, 1.01-1.66). Among untested women, chemotherapy use was higher for AI/AN women; however, the use of chemotherapy was not found to be significantly different between the groups with a high-risk RS. Using Cox proportional hazards models, AI/AN race was found to be significantly associated with worse overall survival.

CONCLUSIONS

AI/AN women were less likely to undergo RS testing compared with NHW women and were more likely to have a high-risk RS. Reversing the disparity in genomic expression assay testing is critical to ensure guideline-based breast cancer treatment and improve survival rates for AI/AN women with breast cancer.

Autologous tissue reconstruction after mastectomy-A cross-sectional survey of 110 hospitals in China

BACKGROUND

Autologous reconstruction after mastectomy became more and more popular, so this study aimed to obtain up-to-date and comprehensive data on autologous reconstruction in China.

METHODS

An electronic questionnaire was sent to 110 hospitals, which were chosen depending on geographical distribution and hospital types. The questionnaire investigated the demographics, characteristics, breast cancer treatment and reconstruction situation of these hospitals through different modules. We only focused on the autologous breast reconstruction module data.

RESULTS

96 hospitals have performed breast reconstruction surgery. The proportion of the hospital performing latissimus dorsi flap (LDF, N = 91), pedicle transverse rectus abdominis myocutaneous flap (pTRAM, N = 62), free abdominal flap (N = 43) and other kinds of flap decreased in sequence. Of the overall reconstruction cases, only 34.3% were autologous reconstruction and LDF was still the most popular option for autologous reconstruction. Related factors of hospital performing different procedures included years of performing breast reconstruction, breast surgical volume, and establishment of an independent plastic surgery department. Compared with LDF, abdominal breast reconstruction was associated with a higher flap necrosis rate.

CONCLUSIONS

This cross-sectional survey offers real-life autologous reconstruction information on a large population and covers the national surgical landscape in China. Autologous reconstruction is still an important part of breast reconstruction. Nevertheless, its low proportion and lower proportion of abdominal flap reconstruction in each institution, demonstrates that special training should be developed for breast surgeons and multidisciplinary cooperation would be promoted in the future.

A Multimetric Health Literacy Analysis of Autologous Versus Implant-Based Breast Reconstruction

BACKGROUND

Over the past decade, the demand for breast reconstruction has mirrored the rising incidence of breast cancer. Common postoncologic surgical options include autologous and implant-based reconstruction. Patient-directed health information for breast reconstruction can play a critical role in the decision-making process. This study comparatively evaluates the top online resources for autologous versus implant-based reconstruction using a multimetric health literacy analysis.

METHODS

The top 10 websites for autologous and implant-based reconstruction were identified using a Google search. A total of 20 unique links were appraised by 2 independent raters for understandability and actionability using the Patient Education Materials Assessment Tool and cultural sensitivity using the Cultural Sensitivity Assessment Tool. A Cohen κ for interrater reliability was calculated. Mean reading grade level and word complexity were also determined.

RESULTS

Websites for both autologous and implant-based modalities exceeded the recommended sixth- to eighth-grade reading level (12.4 and 12.1, respectively; P = 0.65). Mean understandability scores for each modality were low (60.5 and 62.5, P = 0.65). Autologous-based resources had a lower mean actionability score compared with implant-based materials (19.5 and 24, respectively; P = 0.04). Both reconstructive modalities met the threshold for acceptability for cultural sensitivity (2.79 and 2.58, P = 0.09).

CONCLUSIONS

Our study revealed a chasm between the health literacy needs of the average adult and the quality of both implant-based and autologous breast reconstruction resources. Materials for both modalities were often too complex and failed to include tools to facilitate active decision making, particularly for autologous-based reconstruction. Strategies to improve materials should be patient centered and include simplification of reading grade level, incorporation of clear visual aids, and inclusion of procedural risks to promote patient comprehension, participation, and ultimately health outcomes.

A Tale of Two Sisters: Breast Reconstruction Options for Women With or at High Risk of Breast Cancer

Breast reconstructive surgery has changed significantly over the past decade. The incidence of nipple-sparing procedures and prophylactic mastectomy has also increased significantly as women and their surgeons use shared decision-making strategies. The following case history of two sisters, one with breast cancer and one at elevated risk for breast cancer, highlights the current standard of care with newer gold-standard procedures for mastectomy and subsequent reconstruction. A comparison of types of mastectomies, steps in reconstruction, and reconstruction options are discussed.

Closing the Breast Cancer Loop: Barriers and Perceptions of Breast Reconstruction among Rural Women

Background:

Despite policies such as the Women's Health and Cancer Rights Act (WHCRA) and Breast Cancer Patient Education Act, rates for breast reconstruction vary and are especially low for some subpopulations of patients, especially rural women. In order to better understand patient perceptions, qualitative analysis using focus groups is an underutilized tool for obtaining patient perspectives regarding health-related issues and access to care. Our aim was to better understand patient perceptions using qualitative analysis.

Methods:

Three focus groups were held in rural counties within West Virginia in order to better understand patient perceptions, knowledge, and beliefs regarding breast health, breast cancer, access to breast reconstruction, and how to disseminate and educate this patient population regarding their right to accessing breast reconstruction.

Results:

Major themes analyses revealed perceived barriers to care related to lacking care coordination, lack of insurance coverage and other resources, as well as issues related to transportation. Participants consistently discussed avoiding breast screening care due fear and denial in addition to pain. Few patients were aware of their right to accessing breast reconstruction per the WHCRA, and many were concerned about follow-up burden, complications, and general fear related to breast reconstruction. Themes related to dissemination of information to promote the option of breast reconstruction included social media, patient counseling by their referring physician, and other means of intervention in clinics and other points in the care coordination chain.

Conclusions:

Rural women have important, unique viewpoints regarding access to and perceived barriers from obtaining breast reconstruction. Plastic surgeons must work diligently to educate, disseminate, and improve care coordination among this population in order to improve access to breast reconstruction among rural breast cancer patients.

Impact of Physician Payments on Microvascular Breast Reconstruction: An All-Payer Claim Database Analysis

BACKGROUND

Rates of autologous breast reconstruction are stagnant compared with prosthetic techniques. Insufficient physician payment for microsurgical autologous breast reconstruction is one possible explanation. The payment difference between governmental and commercial payers creates a natural experiment to evaluate its impact on method of reconstruction. This study assessed the influence of physician payment differences for microsurgical autologous breast reconstruction and implants by insurance type on the likelihood of undergoing microsurgical reconstruction.

METHODS

The Massachusetts All-Payer Claims Database was queried for women undergoing immediate autologous or implant breast reconstruction from 2010 to 2014. Univariate analyses compared demographic and clinical characteristics between different reconstructive approaches. Logistic regression explored the relative impact of insurance type and physician payments on breast reconstruction modality.

RESULTS

Of the women in this study, 82.7 percent had commercial and 17.3 percent had governmental insurance. Implants were performed in 80 percent of women, whereas 20 percent underwent microsurgical autologous reconstruction. Women with Medicaid versus commercial insurance were less likely to undergo microsurgical reconstruction (16.4 percent versus 20.3 percent; p = 0.063). Commercial insurance, older age, and obesity independently increased the odds of microsurgical reconstruction (p < 0.01). When comparing median physician payments, governmental payers reimbursed 78 percent and 63 percent less than commercial payers for microsurgical reconstruction ($1831 versus $8435) and implants ($1249 versus $3359, respectively). Stratified analysis demonstrated that as physician payment increased, the likelihood of undergoing microsurgical reconstruction increased, independent of insurance type (p < 0.001).

CONCLUSIONS

Women with governmental insurance had lower odds of undergoing microsurgical autologous breast reconstruction compared with commercial payers. Regardless of payer, greater reimbursement for microsurgical reconstruction increased the likelihood of microsurgical reconstruction. Current microsurgical autologous breast reconstruction reimbursements may not be commensurate with physician effort when compared to prosthetic techniques.

Should free deep inferior epigastric artery perforator flaps be considered a quality indicator in breast reconstruction?

Over the past several decades, technical advances in breast reconstruction have resulted in the development of flaps that are aimed at progressively decreasing abdominal wall morbidity. There is, however, ongoing controversy related to the superiority of deep inferior epigastric perforator (DIEP) flaps over muscle-sparing TRAM (MS-TRAM) flaps. Hence, the question remains unanswered as to which approach should be considered the standard of care, and more importantly, whether the rate of DIEP flap utilization should be considered a quality metric in breast reconstruction. In this review article, we examine the literature pertaining to abdominal free tissue transfer in breast reconstruction from both donor site and flap characteristics as well as the resultant complications and morbidity. The impact on the donor site remains a prevailing principle for autologous breast reconstruction; thus, must be adequately respected when classifying what is left behind following flap harvest. The most commonly used nomenclature is too simplistic. This, in turn, leads to inadequate incorporation of critical variables, such as degree of muscular preservation, fascial involvement, mesh implantation, and segmental nerve anatomy. Currently, there is insufficient evidence to support DIEP flap harvest as a quality indicator in breast reconstruction, as DIEP flap outcomes are not clearly superior when compared with MS-TRAM flaps.

National Patterns of Breast Reconstruction and Nipple-Sparing Mastectomy for Breast Cancer, 2005-2015

BACKGROUND

The purpose of this study was to explore national patterns in the uptake of breast reconstruction and nipple-sparing mastectomy (NSM).

METHODS

We used the National Cancer Database to identify all women who underwent mastectomy for stage 0-III breast cancer between 2005-2015. Multivariable logistic regression was used to determine factors associated with receipt of reconstruction, with subset analyses performed to determine trends and predictors of NSM in those who underwent mastectomy with reconstruction.

RESULTS

Our cohort consisted of 395,815 women, 238,568 (60.3%) who underwent mastectomy alone and 157,247 (39.7%) who underwent mastectomy followed by reconstruction. The use of breast reconstruction increased from 22.3% of mastectomy cases in 2005 to 49.7% of mastectomy cases in 2015 (odds ratio [OR] 9.7, 95% confidence interval [CI] 7.3-12.8). Among those receiving reconstruction, the use of NSM increased from 1.7% in 2005 to 14.3% in 2015 (OR 9.4, 95% CI 7.1-12.5), with increased utilization among those with early-stage and locally advanced disease, such that by 2015, NSM was performed in 15.3% of mastectomies with reconstruction for DCIS, 14.3% of mastectomies with reconstruction for stage I-II breast cancer, and 10.7% of mastectomies with reconstruction for stage III breast cancer. Factors strongly predicting receipt of NSM included age < 45 years, smaller clinical tumor size, clinically node negative disease, use of neoadjuvant therapy, and facility type.

CONCLUSIONS

There has been a dramatic increase in the use of breast reconstruction and NSM between 2005-2015. Further prospective studies evaluating oncologic outcomes of NSM in locally advanced breast cancer are warranted.
