Background
Bilateral mastectomy in women diagnosed with unilateral breast cancer is on the rise in the USA. One contributing factor is increased awareness of contralateral breast cancer risk. Positive testing for deleterious mutation in BRCA1/2 is a concrete measure of this contributing factor. We hypothesize that breast cancer surgery trend change is temporally associated with the introduction of BRCA1/2 genetic testing around 1996.Methods
Our study cohort included 158 BRCA1 or BRCA2 mutation carriers diagnosed with unilateral breast cancer between 1963 and 2009. Mutation carriers with ovarian cancer or bilateral breast cancer were excluded. Breast surgery and breast reconstruction surgery trends were analyzed according to year of breast cancer diagnosis or when bilateral mastectomy was performed, respectively.Results
Surgery trends changed significantly over time. We observed a significant drop in the rate of unilateral mastectomy (P < 0.001) after the period 1996–2000, and the rate of bilateral mastectomy appears to be on the rise, up to 30.3% between 2006 and 2009. Breast reconstruction trends also changed significantly over time, with a significant rise in the rate of free flap reconstruction to 58.8% between 2006 and 2009.Conclusions
Our results demonstrated a significant decrease in unilateral mastectomy with a rise in bilateral mastectomy after the period 1996–2000, a period which encompassed the year when genetic testing of the two BRCA1/2 genes became commercially available, hence supporting our hypothesis. 相似文献2.

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.Methods
The American College of Surgeons National Surgery Quality Improvement Program (ACS NSQIP) Participant Use Files between 2007 and 2010 were used to identify women with breast cancer undergoing UM or BM with SLNB. Individual and composite end points of 30-day complications were used to compare both groups by univariate and multivariate analyses.Results
We identified 4,219 breast cancer patients who had a SLNB: 3,722 (88.2 %) had UM and 497 (11.8 %) had BM. The wound complication rate was significantly higher in the BM group versus the UM group, 5.8 % versus 2.9 % [unadjusted odds ratio (OR) 2.1, 95 % confidence interval (CI) 1.3–3.3, P < 0.01]. The overall 30-day complication rate in UM patients was 4.2 % versus 7.6 % in the BM group (unadjusted OR 1.9, 95 % CI 1.3–2.7, P < 0.01). The adjusted OR for overall complications adjusting for important patient characteristics was 1.9 (95 % CI 1.3–2.8, P < 0.01). Independent predictors of overall postoperative complications were body mass index (OR 1.1, P < 0.01) and smoking (OR 2.2, P < 0.01).Conclusions
For patients with breast cancer, bilateral mastectomy is associated with an increased risk of wound and overall postoperative complications. Discussion of these outcomes is imperative when counseling women contemplating CPM. 相似文献3.

Background
In the last decade, there has been increasing use of contralateral prophylactic mastectomy (CPM) in patients with unilateral breast cancer and ductal carcinoma-in-situ (DCIS) undergoing mastectomy. Although many factors have been proposed to explain this trend, the impact of breast reconstruction on CPM has not been studied.Methods
A retrospective review of patients with unilateral invasive breast cancer or DCIS from Surveillance, Epidemiology, and End Results registry data (2004–2008) was conducted. Characteristics of patients undergoing CPM and reconstruction were evaluated.Results
A total of 102,674 patients diagnosed with DCIS or stage I to III infiltrating breast cancer underwent mastectomy for their primary lesion. Of these, 16,197 patients (16 %) underwent a CPM. A significantly higher proportion of women undergoing CPM had reconstruction performed (46 %) than those patients not undergoing CPM (15 %) (p < 0.001). Of the 20,760 patients (20 %) who underwent reconstruction, 7410 (36 %) had implant reconstruction, 7705 (37 %) tissue reconstruction, and 1941 (9 %) combined tissue/implant reconstruction; there were no data for 3,702 (18 %). There was an increasing trend of patients undergoing reconstruction from 2004 (n = 3390, 16.3 %) to 2008 (n = 5406, 26 %) (p < 0.001). On multivariable analysis, significant variables predicting CPM included age <45 years, stage I disease (odds ratio [OR] 1.44, 95 % confidence interval [CI] 1.35–1.54), lobular histology (OR 1.15, 95 % CI 1.11–1.20), and undergoing breast reconstruction (OR 3.58, 95 % CI 3.41–3.75).Conclusions
Besides age, undergoing reconstructive surgery is the factor most strongly associated with CPM. This suggests that apart from risk reduction, the availability of and/or patient willingness to undergo breast reconstruction may influence the decision to undergo CPM. 相似文献4.

Background
Total skin-sparing mastectomy (TSSM) with preservation of the nipple–areolar complex skin has become increasingly accepted as an oncologically safe procedure. Oncologic outcomes after TSSM in BRCA mutation carriers have not been well-studied.Methods
We identified 53 BRCA-positive patients who underwent bilateral TSSM for prophylactic (26 patients) or therapeutic indications (27 patients) from 2001 to 2011. Cases were age-matched (for prophylactic cases) or age- and stage-matched (for therapeutic cases) with non-BRCA-positive patients. Outcomes included tumor involvement of resected nipple tissue, the development of new breast cancers in patients who underwent risk-reducing TSSM, and local–regional recurrence in patients who underwent therapeutic TSSM.Results
Outcomes from 212 TSSM procedures in 53 cases and 53 controls were analyzed. In patients undergoing TSSM for prophylactic indications, in situ cancer was found in one (1.9 %) nipple specimen in BRCA-positive patients versus two specimens (3.8 %) in the non-BRCA-positive cohort (p = 1). At a mean follow-up of 51 months, no new cancers developed in either cohort. In patients undergoing TSSM for therapeutic indications, in situ or invasive cancer was found in zero of the nipple specimens in BRCA-positive patients versus two specimens (3.7 %) in the non-BRCA-positive cohort (p = 0.49). At a mean follow-up of 37 months, there were no local–regional recurrences in the BRCA-positive cohort and 1 (3.7 %) in the non-BRCA-positive cohort.Conclusions
TSSM is an oncologically safe procedure in BRCA-positive patients. In patients undergoing TSSM as a risk-reducing strategy, 4-year follow-up demonstrates no increased risk of developing new breast cancers; longer-term follow-up is ongoing. 相似文献5.

Background
The goal of the present study was to evaluate the impact of delayed autologous breast reconstruction on disease relapse in breast cancer patients treated with mastectomy.Material and methods
The study was based on 503 consecutive patients younger than 70 years of age who underwent mastectomy between January 2000 and December 2003. Overall, 391 (78 %) received mastectomy alone and 112 (22 %) underwent a delayed breast reconstruction. The median time from mastectomy to delayed breast reconstruction was 34 months. The median duration of follow-up was 102 months.Results
There were no locoregional recurrences (LRR) in patients who underwent delayed reconstruction (0.0 %); 21 LRR developed in patients treated with mastectomy only (5.4 %), P = 0.011. Distant metastases occurred less frequently in the reconstruction group (12.5 %) than in the patients who underwent mastectomy alone (21.5 %); P = 0.0343. The 8-year breast cancer specific survival in the reconstruction group was 98.2 and 85.7 % for the mastectomy only group, P = 0.000.Conclusions
Delayed autologous breast reconstruction does not appear to adversely influence disease progression when compared to patients treated with mastectomy only. 相似文献6.

Objective
The performance of a mastectomy for the treatment or prophylaxis of breast cancer may have long-term implications for both physical and mental well-being in women. The development of breast numbness and phantom breast sensations following mastectomy is well-known; however, relatively little is known about physical morbidity following postmastectomy breast reconstruction. The primary objective of this study was to evaluate the level of physical morbidity experienced following three surgical approaches: mastectomy alone, postmastectomy tissue expander/implant reconstruction, and postmastectomy autogenous tissue reconstruction.Methods
We conducted a cross-sectional survey of a sample of women who had undergone mastectomy with or without reconstruction. Chest and upper body morbidity were evaluated using the BREAST-Q. Physical well-being was compared across three types of breast surgery.Results
In total, 308 of 452 women who received a questionnaire booklet returned completed questionnaires. There was an overall difference in physical morbidity attributable to surgical treatment (P < 0.001). Patients who underwent autogenous tissue reconstruction had the highest (i.e., best) mean physical well-being score. Women who underwent expander/implant reconstruction also had less chronic physical morbidity than women who underwent mastectomy alone (P < 0.05).Conclusions
Our findings suggest that women who undergo immediate autogenous tissue reconstruction experience significantly less chest and upper body morbidity than those who undergo either mastectomy with implant-based reconstruction or mastectomy alone. This information can be used to facilitate clinical decision-making, to validate individual experiences of breast cancer survivors, and to inform future innovations to decrease the long-term physical morbidity associated with breast cancer surgery. 相似文献7.

Background
Breast reconstruction improves the quality of life for mastectomy patients but is underutilized in the United States. This study investigated reconstruction rates for a dual-trained oncologic plastic surgeon to explore how provider-based factors influence reconstruction.Methods
We evaluated consecutive mastectomy patients treated at the University of California, San Diego Medical Center between 2009 and 2012. We identified mastectomy patients based on Current Procedural Terminology codes and evaluated them for patient- and disease-specific variables. We evaluated reconstruction rates for the traditional team model of collaborating plastic and oncologic surgeons versus a single surgeon, dual trained in surgical breast oncology and plastic surgery. A multivariate regression analysis was then used to identify the significant predictors of reconstruction.Results
Mastectomy was performed in 344 patients. The surgeon group was a significant predictor of postmastectomy reconstruction (p < 0.05). The traditional team of oncologic and plastic surgeons reconstructed 93 (63.3 %) of 147 mastectomy patients, whereas the single dual-trained surgeon reconstructed 140 (71.1 %) of 197 mastectomy patients. Race and insurance status did not influence the receipt of reconstruction in our single-surgeon model, however, patients of older age [odds ratio (OR) 0.93, confidence interval (CI) 0.89–0.98, p < 0.01], higher body mass index (OR 0.89, CI 0.82–0.97, p < 0.01), or more advanced disease (p < 0.01) were less likely to undergo reconstruction.Conclusions
A single dual-trained surgeon for breast care influences reconstruction rates. A dual-trained surgeon increases the likelihood of reconstruction and obtains rates higher than previously reported. This may reflect the comprehensive care provided by a multidisciplinary-trained professional. A single surgeon providing care in oncology and reconstruction represents a comprehensive approach to breast care and demonstrates a relationship between provider practice and breast reconstruction. 相似文献8.

Background
Contralateral prophylactic mastectomy (CPM) is expected to add surgical morbidity but this incremental risk has not yet been defined. We sought to quantify the additional risks associated with CPM and determine how these risks influence the time to adjuvant therapy.Methods
We identified women undergoing mastectomy for unilateral breast cancer and stratified them according to the use of CPM and the presence and laterality of surgical complications. We measured time to adjuvant therapy.Results
Of 352 patients, 205 (58 %) underwent unilateral mastectomy (UM) and 147 (42 %) underwent bilateral mastectomy (BM) [BM = UM + CPM]. Overall, 94/352 (27 %) women suffered 112 complications (BM: 46/147 [31 %] vs. UM: 48/205 [23 %]; p = 0.11), of which hematoma, skin necrosis, cellulitis, or seroma accounted for 94/112 (84 %) complications. Reoperation was required in 37/352 (10 %) women. Among those undergoing BM, morbidity occurred only in the prophylactic breast in 19/147 (13 %) women and risk did not differ with immediate reconstruction (13/108 [12 %]) or without (6/39 [15 %]). Of these 19 patients, 10 (53 %) required reoperation. Women with any complication had a longer interval to adjuvant therapy when compared with those without (49 days vs. 40 days; p < 0.001). When stratified according to side, complications in the prophylactic breast were not associated with a delay in treatment (UM: 58 days vs. BM: prophylactic side; 41 days vs. BM: cancer side: 50 days; p = 0.73).Conclusions
CPM confers additional morbidity in one in eight women, of whom half require reoperation. Despite this, in our series CPM did not delay adjuvant therapy. Given the rising incidence of patients seeking CPM, they should be informed of this risk. 相似文献9.

Background
Patients with ductal carcinoma in situ (DCIS) are at increased risk for developing contralateral breast cancer (CBC). Consequently, more women with DCIS are electing to undergo contralateral prophylactic mastectomy (CPM). We evaluated factors associated with CPM in patients with DCIS who underwent genetic counseling for BRCA testing.Methods
This retrospective study involved 165 women with DCIS referred for genetic counseling between 2003 and 2011. Patient characteristics were age, marital and educational status, tumor markers, nuclear grade, family history of breast cancer (BC) and ovarian cancer (OC), race, Ashkenazi Jewish ancestry, and BRCA results. Univariate and multivariate logistic regression analyses were used to determine predictive factors associated with CPM election.Results
Of 165 patients, 44 (27 %) underwent CPM. Patients <45 years of age were more likely to elect CPM (p = 0.0098). A BRCA+ mutation was found in 17 patients (10.3 %), and BRCA+ women were more likely to elect CPM than BRCA or untested women (p = 0.0001). Patients who had a family history of OC (57.7 %) were more likely to choose CPM than those with no family history (p = 0.0004). Younger age, BRCA+, and an OC family history remained significant in the multivariate model (p < 0.008).Conclusion
The CPM rate among patients with DCIS who undergo genetic counseling is high. Factors associated with increased likelihood of CPM among this group were age, BRCA+, and a family history of OC. Further studies are needed to evaluate patients’ perceptions of CBC risk and their role in the likelihood of CPM choice. 相似文献10.

Objective
Prophylactic nipple-areolar complex (NAC)-sparing mastectomy (NSM) in BRCA1/2 mutation carriers is controversial over concern regarding residual fibroglandular tissue (FGT) with malignant potential. The objective of this study was to model the volume of FGT in the NAC at a standard retroareolar margin (5 mm) and examine the change in this amount with a greater retroareolar margin or areola-sparing technique.Methods
A segmentation protocol was applied to breast MRIs from 105 BRCA1/2 patients to quantify volumes of FGT for total breast and NAC. The proportion of FGT in the NAC relative to the breast was calculated as the primary outcome and was compared for 5 mm versus 10 mm retroareolar depths. The proportion of FGT in the areola was compared with the NAC.Results
At 5 mm retroareolar thickness, residual NAC FGT comprised 1.3 % of the total breast FGT. This amount was not significantly greater than the proportion in the areola (p = 0.3, d = 0.1). Increasing the retroareolar thickness to 10 mm led to a statistically and possibly clinically significant increase in the amount of NAC FGT (p < 0.001, d = 1.1).Conclusions
The proportion of FGT remaining in the spared NAC with a 5 mm margin is extremely small, suggesting that leaving the entire NAC would create very little added risk. Doubling the retroareolar margin may translate into a clinically meaningful increase. Overall, our findings support the safety of the current trend toward increased rates of prophylactic NSM performed in this high-risk population. 相似文献11.
Background
To make an informed choice, breast cancer patients facing surgery must imagine the effect of surgery on their future life experiences. However, the accuracy of patient predictions of postoperative quality of life (QoL) and disease-related stigma is not well understood.Materials and Methods
Four groups of breast cancer patients at the University of Michigan Medical Center were surveyed by mail and interview (response rate 76.3%): (1) preoperative (N = 59), (2) mastectomy (N = 146), (3) mastectomy with reconstruction (N = 250), and (4) breast conservation (N = 705). Subjects rated their QoL (1 = lowest, 100 = highest) and stigma (1 = lowest, 5 = highest) and estimated QoL and stigma associated with mastectomy alone, mastectomy with reconstruction, and breast conserving surgery (BCS). Mean scores were compared using linear regression controlling for age, race, partnered status, and income.Results
Preoperatively, women inaccurately predicted postoperative QoL and stigma for all surgical options, particularly for mastectomy. Preoperative patients underestimated the postoperative QoL for mastectomy alone (predicted: 56.8 vs actual: 83.7; P < .001). Preoperative patients underestimated QoL following mastectomy following reconstruction (predicted: 73.4 vs actual: 83.9; P < .001) and BCS (predicted: 72.2 vs actual: 88.6; P < .001). Additionally, preoperative patients overestimated stigma related to mastectomy (predicted: 3.25 vs actual: 2.43; P < .001). Finally, preoperative women overestimated stigma related to mastectomy with reconstruction (predicted: 2.54 vs actual: 2.03; P < .001) and BCS (predicted: 1.90 vs actual: 1.76; P < .001).Conclusion
Predicting QoL and stigma following breast cancer surgery is challenging for patients facing a diagnosis for surgery. Identifying strategies to better inform patients of surgical outcomes can improve the decision-making process. 相似文献12.
Contralateral prophylactic mastectomy in breast cancer patients who test negative for BRCA mutations
Background
Determination of BRCA1 and 2 mutation carrier status is important. Although BRCA carriers are offered bilateral mastectomy and oophorectomy, most who test negative decline. Some women choose contralateral prophylactic mastectomy (CPM) at the time of their breast cancer diagnosis despite testing negative.Methods
A total of 110 women with breast cancer received genetic testing before surgical treatment. Patient demographics, tumor characteristics, surgical treatment, and magnetic resonance imaging use were recorded.Results
Results revealed BRCA1/2 mutation in 33%, variant of unknown significance in 6%, and no mutation in 61% of women. In BRCA-negative women, 37% chose CPM. Marital status was significant for CPM (P = .03). Race, age, stage of presentation, and biomarker status were not associated with choice of CPM. Ninety-six percent of CPM recipients underwent breast reconstruction. Magnetic resonance imaging use did not affect CPM rates (P = .99).Conclusions
Increased rates of CPM have been observed. In our study married women were more likely to choose CPM. We recommend genetic genotyping before surgery. These findings warrant further investigation. 相似文献13.

Background
Revised NCCN guidelines recommend that women ≤60 years with triple-negative breast cancer (TNBC) be referred for consideration of genetic counseling. Small, homogeneous samples have limited evaluation of BRCA mutation prevalence among different ethnicities affected by TNBC subtype. We sought to determine whether the prevalence of BRCA mutations within a TNBC cohort differs by demographic factors.Methods
We performed a retrospective review of patients with TNBC referred for genetic counseling at two academic Hereditary Cancer Clinics between 2000 and 2012. Demographic data were collected, including age at diagnosis and race/ethnicity. Race was categorized as African American (AA), Ashkenazi Jewish (AJ), Asian, Caucasian, Hispanic, or other. Primary outcome was BRCA mutation status, analyzed by race/ethnicity and age at diagnosis.Results
A total of 469 patients with TNBC who underwent testing for BRCA genetic mutations were identified, of which 450 patients had evaluable BRCA testing results; 139 (30.8 %) had confirmed BRCA1 (n = 106) or BRCA2 (n = 32) mutations. BRCA mutation prevalence differed by ethnicity and race: AA (20.4 %), AJ (50 %), Asian (28.5 %), Caucasian (33.3 %), and Hispanic (20 %). The prevalence of genetic mutations also differed by age at diagnosis: <40 years (43.8 %), 40–49 years (27.4 %), 50–59 years (25.3 %), 60–69 years (12.5 %), and >70 years (16.6 %).Conclusions
The prevalence of genetic mutations among women with TNBC referred for genetic counseling is high and differs significantly by ethnicity/race and age. This data helps to refine mutation risk estimates among women with TNBC, allowing for more personalized genetic counseling potentially aiding in improved patient decision-making. 相似文献14.

Background
Women with breast cancer increasingly undergo contralateral prophylactic mastectomy (CPM). We evaluated the relationship between preoperative magnetic resonance imaging (MRI) findings and CPM. Other clinicopathologic variables associated with CPM choice and the pathology found in the contralateral breast are also reported.Methods
Newly diagnosed breast cancer patients were prospectively enrolled in the University of Iowa Breast Molecular Epidemiology Resource. Patients with stages 0–III breast cancer who underwent mastectomy for the index cancer were eligible for this analysis. Univariate logistic regression and a multivariate model were used to identify factors predictive of CPM.Results
Among 134 patients (mean age 54.9 years), 53 (39.6 %) chose CPM. On univariate analysis, patients undergoing CPM were more likely to have a preoperative breast MRI (64.2 vs. 39.5 %, p = 0.006) and to have follow-up testing recommended for the contralateral breast (28.3 vs. 4.9 %, p = 0.001). Univariate analysis also associated CPM with younger age (p < 0.0001), BRCA testing (p < 0.0001), BRCA mutation (p = 0.034) and reconstruction performed (p = 0.001). Median age of youngest child at diagnosis varied significantly between the CPM (15.9 years) and non-CPM (24.3 years) groups (p = 0.0018). On multivariate analysis, MRI follow-up recommendation, young age, reconstruction and human epidermal growth factor receptor 2 (HER2) positivity of the index cancer were significantly associated with CPM. Of the CPM specimens, one (1.8 %) had ductal carcinoma-in situ, which had not been identified on MRI.Conclusions
Abnormal findings in the contralateral breast on preoperative MRI, as well as young age, reconstruction and HER2-positive status correlated with CPM choice in this cohort. Occult malignancy was rare. 相似文献15.

Background
To study national trends in the mastectomy rate for treatment of early stage breast cancer.Methods
We analyzed data from the Surveillance, Epidemiology, and End Results database, including 256,081 women diagnosed with T1–2 N0–3 M0 breast cancer from 2000 to 2008. We evaluated therapeutic mastectomy rates by the year of diagnosis and performed a multivariable logistic regression analyses to determine predictors of mastectomy as the treatment choice.Results
The proportion of women treated with mastectomy decreased from 40.1 to 35.6 % between 2000 and 2005. Subsequently, the mastectomy rate increased to 38.4 % in 2008 (p < 0.0001). Simple logistic regression models demonstrated that mastectomy rates between 2005 and 2008 were moderated by age (p < 0.0001), marital status (p = 0.0230), and geographic location (p < 0.0001). Multivariate logistic regression analysis found that age, race, marital status, geographic location, involvement of multiple regions of the breast, lobular histology, increasing T stage, lymph node positivity, increasing grade, and negative hormone receptor status were independent predictors of mastectomy. Additionally, multivariate analysis confirmed that women diagnosed in 2008 were more likely to undergo mastectomy than women diagnosed in 2005 (odds ratio 1.17, 95 % confidence interval 1.13 to 1.21, p < 0.0001).Conclusions
There is evidence of a reversal in the previously declining national mastectomy rates, with the mastectomy rate reaching a nadir in 2005 and subsequently rising. Further follow-up to confirm this trend and investigation to determine the underlying cause of this trend and its effect on outcomes may be warranted. 相似文献16.

Purpose
Analysis of mastectomy rates in breast cancer patients diagnosed between 2006 and 2010 in Germany with focus on impact of breast magnetic resonance imaging (MRI), immediate breast reconstruction (IBR) rates, and hospital volume as possible influencing factors of mastectomy rates.Methods
Data of a voluntary monitored benchmarking project were used to evaluate mastectomy trends across time in an unselected cohort of breast cancer patients. We used univariate and multivariate logistic regression analysis to identify predictive factors of mastectomy.Results
A total of 142.863 cases were included into the analysis. There was an overall decrease of 5.9 % (95 % confidence interval 5.1–6.7) in mastectomy trend from 36.5 % in 2006 to 30.6 % in 2010 (P < 0.0001). Known predictive factors were confirmed. Breast MRI (odds ratio 1.42, 95 % confidence interval 1.36–1.47) and small hospitals (<150 cases per year) seem to favor mastectomy. IBR was not associated with mastectomy rates.Conclusions
Mastectomy rates in comparable health systems differ. Performance of preoperative breast MRI and hospital volume seem to be independent influencing factors for mastectomy rates. 相似文献18.

Background
Regardless of their age, women who choose to undergo postmastectomy reconstruction report improved quality of life as a result. However, actual use of reconstruction decreases with increasing age. Whereas this may reflect patient preference and clinical factors, it may also represent age-based disparity.Methods
Women aged 65 years or older who underwent mastectomy for DCIS/stage I/II breast cancer (2000–2005) were identified in the SEER-Medicare database. Overall and institutional rates of reconstruction were calculated. Characteristics of hospitals with higher and lower rates of reconstruction were compared. Pseudo-R² statistics utilizing a patient-level logistic regression model estimated the relative contribution of institution and patient characteristics.Results
A total of 19,234 patients at 716 institutions were examined. Overall, 6 % of elderly patients received reconstruction after mastectomy. Institutional rates ranged from zero to >40 %. Whereas 53 % of institutions performed no reconstruction on elderly patients, 5.6 % performed reconstructions on more than 20 %. Although patient characteristics (%ΔR² = 70 %), and especially age (%ΔR² = 34 %), were the primary determinants of reconstruction, institutional characteristics also explained some of the variation (%ΔR² = 16 %). This suggests that in addition to appropriate factors, including clinical characteristics and patient preferences, the use of reconstruction among older women also is influenced by the institution at which they receive care.Conclusions
Variation in the likelihood of reconstruction by institution and the association with structural characteristics suggests unequal access to this critical component of breast cancer care. Increased awareness of a potential age disparity is an important first step to improve access for elderly women who are candidates and desire reconstruction. 相似文献19.

Background
National guidelines recommend one dose of perioperative antibiotics for breast surgery and discourage postoperative continuation. However, reported skin and soft tissue infection (SSI) rates after mastectomy range from 1–26 %, higher than expected for clean cases. Utility of routine or selective postoperative antibiotic use for duration of drain presence following mastectomy remains uncertain.Methods
This study included all female patients who underwent mastectomy without reconstruction at our institution between 2005 and 2012. SSI was defined using CDC criteria or clinical diagnosis of cellulitis. Information on risk factors for infection (age, body mass index [BMI], smoking status, diabetes, steroid use), prior breast cancer treatment, drain duration, and antibiotic use was abstracted from medical records. Multivariable logistic regression was used to assess the association between postoperative antibiotic use and the occurrence of SSI, adjusting for concurrent risk factors.Results
Among 480 patients undergoing mastectomy without reconstruction, 425 had sufficient documentation for analysis. Of these, 268 were prescribed antibiotics (63 %) at hospital discharge. An overall SSI rate of 7.3 % was observed, with 14 % of patients without postoperative antibiotics developing SSI compared with 3.4 % with antibiotics (p < 0.0001). Factors independently associated with SSI were smoking and advancing age. Diabetes, steroid use, BMI, prior breast surgery, neoadjuvant chemotherapy, prior radiation, concomitant axillary surgery, and drain duration were not associated with increased SSI rates.Conclusions
SSI rates among patients who did and did not receive postoperative antibiotics after mastectomy were significantly different, particularly among smokers and women of advanced age. These patient subgroups may warrant special consideration for postoperative antibiotics. 相似文献20.
