A paradigm shift in U.S. breast reconstruction: Part 2. The influence of changing mastectomy patterns on reconstructive rate and method.
TL;DR: There is increasing use of bilateral mastectomies in the United States, particularly in patients with unilateral cancer, and implant use has increased for all mastectomy types, but they are used most commonly following bilateral and contralateral prophylactic mastectomy.
Abstract: BACKGROUND The aims of the current study were to (1) measure trends in the type of mastectomy performed, (2) evaluate sociodemographic/hospital characteristics of patients undergoing contralateral prophylactic mastectomy versus unilateral mastectomies, and (3) analyze reconstruction rates and method used following different mastectomy types. METHODS Mastectomies from 1998 to 2008 were analyzed using the Nationwide Inpatient Sample database. Mastectomies (n = 178,603) were classified as either unilateral, contralateral prophylactic, or bilateral prophylactic. Reconstructive procedures were categorized into either implant or autologous. Longitudinal trends were analyzed with Poisson regression and sociodemographic/hospital variables were analyzed with logistic regression. RESULTS Unilateral mastectomies decreased 2 percent per year, whereas contralateral and bilateral prophylactic mastectomies increased significantly by 15 and 12 percent per year, respectively (p < 0.01). Independent predictors for contralateral prophylactic mastectomy (compared with unilateral mastectomy) were patients younger than 39 years, Caucasian and Hispanic race, private insurance carriers, treated in teaching hospitals, and from South and Midwest regions. Contralateral prophylactic mastectomy is the only group with increased reconstruction rates throughout the study period (p < 0.01). Although implant use increased for all mastectomy types, it remains greater in bilateral and contralateral prophylactic mastectomy. CONCLUSIONS There is increasing use of bilateral mastectomies in the United States, particularly in patients with unilateral cancer. Although implant use has increased for all mastectomy types, they are used most commonly following bilateral and contralateral prophylactic mastectomies. Changing mastectomy patterns are one factor underlying the paradigm shift away from autologous tissue to implant-based reconstruction.

TL;DR: The increased use of radiation as an adjuvant treatment for management of breast cancer has created additional challenges for plastic surgeons who need to consider the optimal timing and method of breast reconstruction to perform in these patients.
Abstract: Postmastectomy immediate breast reconstruction in the U.S. continues to experience an upward trend owing to heightened awareness, innovations in reconstructive technique, growing evidence of improved patient-reported outcomes, and shifts in mastectomy patterns. Women with unilateral breast cancer are increasingly electing to undergo contralateral prophylactic mastectomy, instead of unilateral mastectomy or opting for breast conservation. The ascent in prophylactic surgeries correlates temporally to a shift toward prosthetic methods of reconstruction as the most common technique. Factors associated with the choice for implants include younger age, quicker recovery time, along with documented safety and enhanced aesthetic outcomes with newer generations of devices. Despite advances in autologous transfer, its growth is constrained by the greater technical expertise required to complete microsurgical transfer and potential barriers such as poor relative reimbursement. The increased use of radiation as an adjuvant treatment for management of breast cancer has created additional challenges for plastic surgeons who need to consider the optimal timing and method of breast reconstruction to perform in these patients.

TL;DR: Patients who underwent autologous breast reconstruction were more satisfied with their breasts and had greater psychosocial well-being and sexual well- Being than did those who underwent implant reconstruction.
Abstract: Importance Previous outcome studies comparing implant and autologous breast reconstruction techniques have been limited by short-term follow-up, single-center design, and a lack of rigorous patient-reported outcome data. An understanding of the expected satisfaction and breast-related quality of life associated with each type of procedure is central to the decision-making process. Objective To determine outcomes reported by patients undergoing postmastectomy breast reconstruction using implant or autologous techniques 2 years after surgery. Design, Setting, and Participants Patients were recruited from 11 centers (57 plastic surgeons) across North America for the Mastectomy Reconstruction Outcomes Consortium study, a prospective, multicenter trial, from February 1, 2012, to July 31, 2015. Women undergoing immediate breast reconstruction using implant or autologous tissue reconstruction after mastectomy for cancer treatment or prophylaxis were eligible. Overall, 2013 women (1490 implant and 523 autologous tissue reconstruction) met the inclusion criteria. All patients included in this analysis had 2 years of follow-up. Exposures Procedure type (ie, implant vs autologous tissue reconstruction). Main Outcomes and Measures The primary outcomes of interest were scores on the BREAST-Q, a validated, condition-specific, patient-reported outcome instrument, which were collected prior to and at 2 years after surgery. The following 4 domains of the BREAST-Q reconstruction module were evaluated: satisfaction with breasts, psychosocial well-being, physical well-being, and sexual well-being. Responses from each scale were summed and transformed on a 0 to 100 scale, with higher numbers representing greater satisfaction or quality of life. Results Of the 2013 women in the study (mean [SD] age, 48.1 [10.5] years for the group that underwent implant-based reconstruction and 51.6 [8.7] years for the group that underwent autologous reconstruction), 1217 (60.5%) completed questionnaires at 2 years after reconstruction. After controlling for baseline patient characteristics, patients who underwent autologous reconstruction had greater satisfaction with their breasts (difference, 7.94; 95% CI, 5.68-10.20;P Conclusions and Relevance At 2 years, patients who underwent autologous reconstruction were more satisfied with their breasts and had greater psychosocial well-being and sexual well-being than did those who underwent implant reconstruction. These findings can inform patients and their clinicians about expected satisfaction and quality of life outcomes of autologous vs implant-based procedures and further support the adoption of shared decision making in clinical practice.

TL;DR: For patients with breast cancer, bilateral mastectomy is associated with an increased risk of wound and overall postoperative complications and Discussion of these outcomes is imperative when counseling women contemplating CPM.
Abstract: Background
Recent studies indicate that women with unilateral breast cancer are choosing contralateral prophylactic mastectomy (CPM) at an increasing rate. There is limited literature evaluating the postoperative complication rates associated with CPM without breast reconstruction. The objective of this study was to compare postoperative complications in women undergoing unilateral mastectomy (UM) and sentinel lymph node biopsy (SLNB) to those undergoing bilateral mastectomy (BM) and SLNB for the treatment of their breast cancer.

TL;DR: This study presents the largest prospective examination of PROs in PMR to date, comparing PROs from patients undergoing implant-based breast reconstruction (IBR) or autologous breast reconstruction(ABR) using the BREAST-Q, and demonstrated that ABR patients had greater postoperative satisfaction with breast scores at all timepoints compared with IBR patients.
Abstract: Objective:To better understand the long-term patient-reported outcomes (PROs) in satisfaction and health-related quality of life (QOL) following post-mastectomy reconstruction (PMR) using the BREAST-Q, comparing PROs from patients undergoing implant-based breast reconstruction (IBR) or autologous br

...With increasing breast cancer incidence and longer survivorship, the patient’s perspective of care is increasingly important in outcome discussions and assessment.(1,6,7,23) This study demonstrates that postoperative ABR SATBR scores appear to remain high into long-term follow-up and are significantly better than IBR SATBR scores....

...The belief behind the decrease in long-term satisfaction and QOL following IBR is that the appearance of implant reconstruction tends to deteriorate over time, likely due to asymmetric breast ptosis and capsular contracture of the implant.(6) This concept was supported by a 2009 study by Hu et al, 25 utilizing an early version of the BREASTQ....

TL;DR: MRI can detect cancer in the contralateral breast that is missed by mammography and clinical examination at the time of the initial breast-cancer diagnosis, according to a study of 969 women with a recent diagnosis of unilateral breast cancer.
Abstract: Even after careful clinical and mammographic evaluation, cancer is found in the contralateral breast in up to 10% of women who have received treatment for unilateral breast cancer. We conducted a study to determine whether magnetic resonance imaging (MRI) could improve on clinical breast examination and mammography in detecting contralateral breast cancer soon after the initial diagnosis of unilateral breast cancer. Methods A total of 969 women with a recent diagnosis of unilateral breast cancer and no abnormalities on mammographic and clinical examination of the contralateral breast underwent breast MRI. The diagnosis of MRI-detected cancer was confirmed by means of biopsy within 12 months after study entry. The absence of breast cancer was determined by means of biopsy, the absence of positive findings on repeat imaging and clinical examination, or both at 1 year of follow-up. Results MRI detected clinically and mammographically occult breast cancer in the contralateral breast in 30 of 969 women who were enrolled in the study (3.1%). The sensitivity of MRI in the contralateral breast was 91%, and the specificity was 88%. The negative predictive value of MRI was 99%. A biopsy was performed on the basis of a positive MRI finding in 121 of the 969 women (12.5%), 30 of whom had specimens that were positive for cancer (24.8%); 18 of the 30 specimens were positive for invasive cancer. The mean diameter of the invasive tumors detected was 10.9 mm. The additional number of cancers detected was not influenced by breast density, menopausal status, or the histologic features of the primary tumor. Conclusions MRI can detect cancer in the contralateral breast that is missed by mammography and clinical examination at the time of the initial breast-cancer diagnosis.

TL;DR: Although the reason for the increase in implant use is multifactorial, changes in mastectomy patterns, such as increased use of bilateral mastectomies, are one important contributor.
Abstract: Background:Despite its benefits in body image, self-esteem, sexuality, and quality of life, historically fewer than 25 percent of patients undergo immediate breast reconstruction. After passage of the Women Health and Cancer Rights Act, studies failed to demonstrate changes in reconstructive rates.

TL;DR: The use of contralateral prophylactic mastectomy in the United States more than doubled within the recent 6-year period, and young patient age, non-Hispanic white race, lobular histology, and previous cancer diagnosis were associated with significantly higher rates.
Abstract: Purpose Many patients with unilateral breast cancer choose contralateral prophylactic mastectomy to prevent cancer in the opposite breast. The purpose of our study was to determine the use and trends of contralateral prophylactic mastectomy in the United States. Patients and Methods We used the Surveillance, Epidemiology and End Results database to review the treatment of patients with unilateral breast cancer diagnosed from 1998 through 2003. We determined the rate of contralateral prophylactic mastectomy as a proportion of all surgically treated patients and as a proportion of all mastectomies. Results We identified 152,755 patients with stage I, II, or III breast cancer; 4,969 patients chose contralateral prophylactic mastectomy. The rate was 3.3% for all surgically treated patients; 7.7%, for patients undergoing mastectomy. The overall rate significantly increased from 1.8% in 1998 to 4.5% in 2003. Likewise, the contralateral prophylactic mastectomy rate for patients undergoing mastectomy significantly increased from 4.2% in 1998 to 11.0% in 2003. These increased rates applied to all cancer stages and continued to the end of our study period. Young patient age, non-Hispanic white race, lobular histology, and previous cancer diagnosis were associated with significantly higher rates. Large tumor size was associated with a higher overall rate, but with a lower rate for patients undergoing mastectomy. Conclusion The use of contralateral prophylactic mastectomy in the United States more than doubled within the recent 6-year period of our study. Prospective studies are needed to understand the decision-making processes that have led to more aggressive breast cancer surgery.

TL;DR: The use of CPM for DCIS in the United States markedly increased from 1998 through 2005, and young patient age, white race, recent year of diagnosis, and the presence of lobular carcinoma in situ were significantly associated with higher CPM rates among all surgical patients and all patients undergoing mastectomy.
Abstract: Purpose Some women with unilateral ductal carcinoma in situ (DCIS) undergo contralateral prophylactic mastectomy (CPM) to prevent cancer in the opposite breast. The use and trends of CPM for DCIS in the United States have not previously been reported. Methods We used the Surveillance, Epidemiology, and End Results database to analyze the initial treatment (within 6 months) of patients with unilateral DCIS diagnosed from 1998 through 2005. We determined the CPM rate as a proportion of all surgically treated patients and as a proportion of all patients who underwent mastectomy. We compared demographic and tumor variables in women with unilateral DCIS who underwent surgical treatment. Results We identified 51,030 patients with DCIS; 2,072 patients chose CPM. The CPM rate was 4.1% for all surgically treated patients and 13.5% for patients undergoing mastectomy. Among all surgically treated patients (including breast-conserving surgery), the CPM rate increased by 148% from 1998 (2.1%) to 2005 (5.2%). Among pat...

TL;DR: Data suggest that increasing use of CPM is not associated with increased recognition of patients at high risk for CBC, and treatment factors, such as immediate reconstruction, preoperative MRI, and unsuccessful attempts at breast conservation, are associated withincreased rates of C PM.
Abstract: Purpose To determine whether increasing rates of contralateral prophylactic mastectomy (CPM) are due to recognition of risk factors for contralateral breast cancer (CBC) or treatment factors related to the index lesion. Methods From 1997 to 2005, 2,965 patients with stage 0 to III primary unilateral breast cancer underwent mastectomy at Memorial Sloan-Kettering Cancer Center. Patients who did and did not undergo CPM within 1 year of treatment for their index cancer were compared to identify independent predictors of CPM. Results The rate of CPM was 13.8% (n = 407), increasing from 6.7% in 1997 to 24.2% in 2005 (P < .0001). Patients with BRCA mutations or prior mantle radiation (n = 52) accounted for 13% of those having CPM. The rate of CPM by surgeon varied from 1% to 26%. Multivariate logistic regression adjusting for surgeon-identified white race (odds ratio [OR] = 3.3), immediate reconstruction (OR = 3.3), family history of breast cancer (OR = 2.9), magnetic resonance imaging (MRI) at diagnosis (OR = 2...
