Race and Breast Cancer Reconstruction: Is There a Health Care Disparity?

Race and Breast Cancer Reconstruction: Is There a Health Care Disparity?
 Plastic and Reconstructive Surgery
Sharma K et al

Background: Racial disparity continues to be a well-documented problem afflicting contemporary health care. Because the breast is a symbol of femininity, breast reconstruction is critical to mitigating the psychosocial stigma of a breast cancer diagnosis. Whether different races have equitable access to breast reconstruction remains unknown. Methods: Two thousand five hundred thirty-three women underwent first-time autologous versus implant-based reconstruction following mastectomy. Information regarding age, smoking, diabetes, obesity, provider, race, pathologic stage, health insurance type, charge to insurance, and socioeconomic status was recorded. Established statistics compared group medians and proportions. A backward-stepwise multivariate logistic regression model identified independent predictors of breast reconstruction type. Results: Compared with whites, African Americans were more likely to be underinsured (p < 0.01), face a lesser charge for reconstruction (p < 0.01), smoke (p < 0.01), have diabetes (p < 0.01), suffer from obesity (p < 0.01), live in a zip code with a lower median household income (p < 0.01), and undergo autologous-based reconstruction (p = 0.01). On multivariate analysis, only African American race (OR, 2.23; p < 0.01), charge to insurance (OR, 1.00; p < 0.01), and provider (OR, 0.96; p < 0.01) independently predicted type of breast reconstruction, whereas age (OR, 1.02; p = 0.06) and diabetes (OR, 0.48; p = 0.08) did not. Conclusions: African American race remains the most clinically significant predictor of autologous breast reconstruction, even after controlling for age, obesity, pathologic stage, health insurance type, charge to patient, socioeconomic status, smoking, and diabetes. Future research may address whether this disparity stems from patient preferences or more profound sociocultural and economic forces, including discrimination. 

The rise in bilateral mastectomies: Evidence, ethics, and physician's role

The rise in bilateral mastectomies: Evidence, ethics, and physician's role

The Breast
Yang YT et al

This viewpoint reviews double mastectomies' trend, medical evidence and ethical considerations, as well as the role of the physician in counseling the patient. It concludes that physicians should encourage patients to pursue alternative preventive measures, and promote bilateral mastectomies only for high-risk patients for whom the potential benefits of the surgery are sufficient to justify the surgery's increased risks.

Buchanan PJ et al

Background: Little is known about the role breast reconstruction plays in decisions made for contralateral prophylactic mastectomy. This study explores factors critical to patient medical decision-making for contralateral prophylactic mastectomy and reconstruction among women with early stage, unilateral breast cancer. Methods: A mixed methods approach was used to gain an understanding of patients’ choices and experiences. Patients with stage 0 to III unilateral breast cancer who underwent reconstruction were recruited, and semistructured interviews were conducted. Patient-reported outcomes were evaluated using the Concerns About Recurrence Scale and the BREAST-Q. Results: Thirty patients were enrolled; 13 (43 percent) underwent unilateral mastectomy and 17 (57 percent) underwent contralateral prophylactic mastectomy. Three broad categories emerged from patient interviews: medical decision-making, quality of life after mastectomy, and breast reconstruction expectations. Patients who chose contralateral prophylactic mastectomy made the decision for mastectomy based primarily on worry about recurrence. Quality of life after mastectomy was characterized by relief of worry, especially in patients who chose contralateral prophylactic mastectomy [n = 14 (82.4 percent)]. Patients’ desires for symmetry, although not the primary reason for contralateral prophylactic mastectomy, played a role in supporting decisions made. Levels of worry after treatment were similar in both groups (72.7 percent). Patients with contralateral prophylactic mastectomy had higher mean scores for satisfaction with breast (82.4 versus 70.6) and satisfaction with outcome (89.9 versus 75.2). Conclusions: The choice for contralateral prophylactic mastectomy is greatly influenced by fear of recurrence, with desires for symmetry playing a secondary role in decisions made. 

Acellular Dermal Matrix–Assisted Direct-to-Implant Breast Reconstruction and Capsular Contracture: A 13-Year Experience

Acellular Dermal Matrix–Assisted Direct-to-Implant Breast Reconstruction and Capsular Contracture: A 13-Year Experience
Plastic and Reconstructive Surgery
Salzburg C et al

Background: Use of acellular dermal matrix for implant-based breast reconstruction appears to be associated with a lower incidence of capsular contracture compared with standard reconstruction. The majority of acellular dermal matrix studies were, however, of short duration; thus, long-term incidence of capsular contracture with acellular dermal matrix use is unknown. Methods: Patients undergoing acellular dermal matrix–assisted breast reconstruction from December of 2001 to May of 2014 at two institutions were evaluated. Cumulative incidence of capsular contracture was determined by the performing surgeon. A retrospective chart review was performed on prospectively gathered data on patient-, breast-, surgery-, and implant-related characteristics that were analyzed as potential risk factors for the development of capsular contracture. Results: A total of 1584 breast reconstructions in 863 patients were performed.....................

Comparison of Outcomes following Autologous Breast Reconstruction Using the DIEP and Pedicled TRAM Flaps: A 12-Year Clinical Retrospective Study and Literature Review

Comparison of Outcomes following Autologous Breast Reconstruction Using the DIEP and Pedicled TRAM Flaps: A 12-Year Clinical Retrospective Study and Literature Review

Knox AD, et al

Background: There are few studies that compare the deep inferior epigastric artery perforator (DIEP) flap to the pedicled transverse rectus abdominis myocutaneous (pTRAM) flap for use in reconstructive breast surgery. The authors examined four factors that aid in decision-making: donor-site morbidity, need for surgery related to abdominal morbidity, operative time, and complications. Methods: This is a retrospective review of patients undergoing breast reconstruction using the DIEP or pTRAM flap at the University of British Columbia between 2002 and 2013. The authors compared operative time and abdomen- and flap-related complications in both groups. Results: Reconstruction was performed in 507 patients; 25.6 percent received DIEP flaps (n = 183 breasts) and 74.4 percent underwent pTRAM flap surgery (n = 444 breasts). Pedicled TRAM flap patients were more likely to require abdominal closure with mesh (44.2 percent versus 8.1 percent; p < 0.001); 21.2 percent of them had a postoperative bulge and/or hernia versus 3.1 percent of DIEP flap patients; and 12.7 percent of pTRAM flap patients required surgery for hernia/bulge. Controlling for confounders, there were five times the odds of a hernia/bulge in the pTRAM flap group. DIEP flap surgery was 234 minutes longer than pTRAM flap surgery. Conclusions: The benefits of the pTRAM flap may be offset by the need to correct abdominal wall complications. DIEP flap reconstruction had lower donor complications but increased operative time. A cost analysis is needed to determine the most economical procedure. 

Validated biomarkers: The key to precision treatment in patients with breast cancer

Validated biomarkers: The key to precision treatment in patients with breast cancer

The Breast
Duffy MJ et al

Recent DNA sequencing and gene expression studies have shown that at a molecular level, almost every case of breast cancer is unique and different from other breast cancers. For optimum management therefore, every patient should receive treatment that is guided by the molecular composition of their tumor, i.e., precision treatment. While such a scenario is still some distance into the future, biomarkers are beginning to play an important role in preparing the way for precision treatment. In particular, biomarkers are increasingly being used for predicting patient outcome and informing as to the most appropriate type of systemic therapy to be administered. Mandatory biomarkers for every newly diagnosed case of breast cancer are estrogen receptors and progesterone receptors in selecting patients for endocrine treatment and HER2 for identifying patients likely to benefit from anti-HER2 therapy. Amongst the best validated prognostic biomarker tests are uPA/PAI-1, MammaPrint and Oncotype DX. Although currently, there are no biomarkers available for predicting response to specific forms of chemotherapy, uPA/PAI-1 and Oncotype DX can aid the identification of lymph node-negative patients that are most likely to benefit from adjuvant chemotherapy, in general. In order to accelerate progress towards precision treatment for women with breast cancer, we need additional predictive biomarkers, especially for enhancing the positive predictive value for endocrine and anti-HER2 therapies, as well as biomarkers for predicting response to specific forms of chemotherapy. The ultimate biomarker test for achieving the goal of precision treatment for patients with breast cancer will likely require a combination of gene sequencing and transcriptomic analysis of every patient's tumor.

10 year survival after breast-conserving surgery plus radiotherapy compared with mastectomy in early breast cancer in the Netherlands: a population-based study

10 year survival after breast-conserving surgery plus radiotherapy compared with mastectomy in early breast cancer in the Netherlands: a population-based study
  The Lancet Oncology
van Maaren MC et al
Adjusting for confounding variables, breast-conserving surgery plus radiotherapy showed improved 10 year overall and relative survival compared with mastectomy in early breast cancer, but 10 year distant metastasis-free survival was improved with breast-conserving surgery plus radiotherapy compared with mastectomy in the T1N0 subgroup only, indicating a possible role of confounding by severity. These results suggest that breast-conserving surgery plus radiotherapy is at least equivalent to mastectomy with respect to overall survival and may influence treatment decision making for patients with early breast cancer.

Glassey R, Ives A, Saunders C, Musiello T

A bilateral prophylactic, or preventative, mastectomy (BPM) for women at high risk of developing breast cancer (BC) can reduce their risk of developing the disease by up to 90% (relative risk reduction). An increasing number of women, including young women, are taking up this option. However, there is a dearth of information for younger women (under 40 years) choosing preventative mastectomy. In fact, no studies to date have specifically focused on younger women's experiences of a BPM and investigated their informational needs.

Turfe Z et al

The Mascagni lymphatic pathway comprises superficial channels along the clavicle that drain upper extremity lymph. A 65 year-old woman with recurrent left breast cancer presented with a non-functioning chemotherapy port in the right deltopectoral groove. She had undergone right mastectomy with axillary lymph node dissection (ALND). After port removal and wound closure she developed right upper extremity lymphedema. Patients who have undergone ALND may depend solely on this pathway for upper extremity lymphatic drainage.

The accuracy of breast volume measurement methods: A systematic review



The Breast August 2016 Volume 28, Pages 121–129
Choppin, SB et al

Breast volume is a key metric in breast surgery and there are a number of different methods which measure it. However, a lack of knowledge regarding a method's accuracy and comparability has made it difficult to establish a clinical standard. We have performed a systematic review of the literature to examine the various techniques for measurement of breast volume and to assess their accuracy and usefulness in clinical practice. Each of the fifteen studies we identified had more than ten live participants and assessed volume measurement accuracy using a gold-standard based on the volume, or mass, of a mastectomy specimen
