Project description:ObjectiveTo compare long-term quality of life (QOL) outcomes in breast cancer survivors who received breast-conserving surgery with radiotherapy (BCS+RT) with those who received a mastectomy and reconstructive surgery (Mast+Recon) without radiotherapy and identify other important factors.BackgroundThe long-term differences in patient-reported QOL outcomes following BCS+RT and Mast+Recon are not well understood.MethodsWe identified patients from the Texas Cancer Registry with stage 0-II breast cancer diagnosed in 2009-2014 after BCS+RT or Mast+Recon without radiotherapy. Sampling was stratified by age and race and ethnicity. A paper survey was sent to 4800 patients which included validated BREAST-Q and PROMIS modules. Multivariable linear regression models were implemented for each outcome. Minimal clinically important difference for BREAST-Q and PROMIS modules, respectively, was 4 points and 2 points.ResultsOf 1215 respondents (25.3% response rate), 631 received BCS+RT and 584 received Mast+Recon. The median interval from diagnosis to survey completion was 9 years. In adjusted analysis, Mast+Recon was associated with worse BREAST-Q psychosocial well-being (effect size: -3.80, P =0.04) and sexual well-being (effect size: -5.41, P =0.02), but better PROMIS physical function (effect size: 0.54, P =0.03) and similar BREAST-Q satisfaction with breasts, physical well-being, and PROMIS upper extremity function ( P >0.05) compared with BCS+RT. Only the difference in sexual well-being reached clinical significance. Older (≥65) patients receiving BCS+RT and younger (<50) patients receiving autologous Mast+Recon typically reported higher QOL scores. Receipt of chemotherapy was associated with detriments to multiple QOL domains.ConclusionsPatients who underwent Mast+Recon reported worse long-term sexual well-being compared with BCS+RT. Older patients derived a greater benefit from BCS+RT, while younger patients derived a greater benefit from Mast+Recon. These data inform preference-sensitive decision-making for women with early-stage breast cancer.

Project description:BackgroundAlthough breast-conserving surgery is oncologically safe for women with early-stage breast cancer, mastectomy rates are increasing. The objective of this study was to examine the role of breast reconstruction in the surgical management of unilateral early-stage breast cancer.MethodsA retrospective cohort study of women diagnosed with unilateral early-stage breast cancer (1998 to 2011) identified in the National Cancer Data Base was conducted. Rates of breast-conserving surgery, unilateral and bilateral mastectomy with contralateral prophylactic procedures (per 1000 early-stage breast cancer cases) were measured in relation to breast reconstruction. The association between breast reconstruction and surgical treatment was evaluated using a multinomial logistic regression, controlling for patient and disease characteristics.ResultsA total of 1,856,702 patients were included. Mastectomy rates decreased from 459 to 360 per 1000 from 1998 to 2005 (p < 0.01), increasing to 403 per 1000 in 2011 (p < 0.01). The mastectomy rates rise after 2005 reflects a 14 percent annual increase in contralateral prophylactic mastectomies (p < 0.01), as unilateral mastectomy rates did not change significantly. Each percentage point of increase in reconstruction rates was associated with a 7 percent increase in the probability of contralateral prophylactic mastectomies, with the greatest variation explained by young age(32 percent), breast reconstruction (29 percent), and stage 0 (5 percent).ConclusionsSince 2005, an increasing proportion of early-stage breast cancer patients have chosen mastectomy instead of breast-conserving surgery. This trend reflects a shift toward bilateral mastectomy with contralateral prophylactic procedures that may be facilitated by breast reconstruction availability.

Project description:BackgroundRecent evidence suggests a survival advantage after breast-conserving surgery compared with mastectomy. Previous studies have compared survival outcomes after standard breast-conserving surgery, but no studies have compared survival outcomes after oncoplastic breast-conserving surgery. The aim of this study was to compare survival outcomes after breast-conserving surgery + radiotherapy (and an oncoplastic breast-conserving surgery + radiotherapy subgroup) with those after mastectomy ± radiotherapy.MethodsPatients diagnosed with primary invasive breast cancer between 1 January 2010 and 31 December 2019 were identified from a prospectively maintained National Cancer Registry. Overall survival and breast cancer-specific survival outcomes were analysed using Kaplan-Meier analysis and Cox regression analysis adjusting for patient demographics, tumour characteristics, and treatment adjuncts.ResultsA total of 14 182 patients were eligible (8537 patients underwent standard breast-conserving surgery + radiotherapy, 360 patients underwent oncoplastic breast-conserving surgery + radiotherapy, 2953 patients underwent mastectomy + radiotherapy, and 2332 patients underwent mastectomy - radiotherapy). The median follow-up was 7.27 (range 0.2-13.6) years. Superior 10-year survival was observed after breast-conserving surgery + radiotherapy (overall survival: 81.2%; breast cancer-specific survival: 93.3%) compared with mastectomy + radiotherapy (overall survival: 63.4%; breast cancer-specific survival: 75.9%) and mastectomy - radiotherapy (overall survival: 63.1%; breast cancer-specific survival: 87.5%). Ten-year overall survival and breast cancer-specific survival after oncoplastic breast-conserving surgery + radiotherapy were 86.1% and 90.2% respectively. After adjusted analysis, breast-conserving surgery + radiotherapy was associated with superior survival outcomes compared with mastectomy + radiotherapy (overall survival: HR 1.34 (95% c.i. 1.20 to 1.51); breast cancer-specific survival: HR 1.62 (95% c.i. 1.38 to 1.90)) and mastectomy - radiotherapy (overall survival: HR 1.57 (95% c.i. 1.41 to 1.75); breast cancer-specific survival: HR 1.70 (95% c.i. 1.41 to 2.05)). Similar survival outcomes were observed amongst patients treated with oncoplastic breast-conserving surgery + radiotherapy compared with mastectomy + radiotherapy (overall survival: HR 1.72 (95% c.i. 1.62 to 2.55); breast cancer-specific survival: HR 1.74 (95% c.i. 1.06 to 2.86)) and mastectomy - radiotherapy (overall survival: HR 2.21 (95% c.i. 1.49 to 3.27); breast cancer-specific survival: HR 1.89 (95% c.i. 1.13 to 3.14)).ConclusionBreast-conserving surgery + radiotherapy and oncoplastic breast-conserving surgery + radiotherapy are associated with superior overall survival and breast cancer-specific survival compared with mastectomy ± radiotherapy. The findings should inform discussion of surgical treatment options for patients with breast cancer.

Project description:BackgroundSalvage mastectomy (SM) is the standard surgery for ipsilateral breast tumour recurrence (IBTR). However, whether repeat breast-conserving surgery (RBCS) is an alternative method remains unclear. We performed a meta-analysis to compare the effects of RBCS and SM after IBTR for breast-conserving surgery (BCS).MethodsWe searched PubMed, Cochrane, Wiley Online and Embase for controlled studies comparing RBCS and SM after IBTR for BCS (published between 1993 and 2019, published in English). Our main endpoints were the secondary local recurrence rate (SLRR), distant metastasis rate (DMR) and overall survival (OS). We used a random-effects model or fixed-effects model for data pooling.ResultsFifteen of the 424 eligible studies were ultimately included, and all studies were retrospective cohort studies (n=2532 participants). 1) SLRR: The SLRR of RBCS was higher than SM (pooled relative rate (pRR) = 1.87, 95% CI 1.22 - 2.86, P=0.004). Stratified analysis was performed according to whether radiotherapy was performed after salvage surgery (radiotherapy group: 2ndRT, no radiotherapy group: no-2ndRT), and the following results were revealed: pRR=0.43 (95% CI 0.20-0.95, P=0.04) for group 2ndRT; and pRR=2.30 (95% CI 1.72-3.06, P<0.00001) for group no-2ndRT. These results showed that the main cause of heterogeneity was salvage radiotherapy. 2) DMR: No significant difference in the DMR was observed between RBCS and SM (pRR = 0.61, 95% CI 0.37 - 1.01, P=0.05). 3) OS: No significant difference in OS was observed between RBCS and SM (pRR=0.65, 95% CI 0.39 - 1.08, P=0.10).ConclusionsThe SLRR of RBCS was higher than SM for ITBR after BCS, but survival was not affected. RBCS may be used as an alternative for IBTR patients after BCS with strict control for several indications, such as tumor size, recurrence interval and biological behavior, and attaching importance to subsequent salvage radiotherapy and systematic therapy.

Project description:Background:Mastectomy rates among women with early breast cancer in Asia have traditionally been high. This study assessed trends in the surgical management of young women with early-stage breast cancer in Asian settings. Survival in women treated with breast-conserving surgery (BCS; lumpectomy with adjuvant radiotherapy) and those undergoing mastectomy was compared. Methods:Young women (aged less than 50 years) newly diagnosed with stage I or II (T1-2 N0-1 M0) breast cancer in four hospitals in Malaysia, Singapore and Hong Kong in 1990-2012 were included. Overall survival (OS) was compared for patients treated by BCS and those who had a mastectomy. Propensity score analysis was used to account for differences in demographic, tumour and treatment characteristics between the groups. Results:Some 63·5 per cent of 3536 women underwent mastectomy. Over a 15-year period, only a modest increase in rates of BCS was observed. Although BCS was significantly associated with favourable prognostic features, OS was not significantly different for BCS and mastectomy; the 5-year OS rate was 94·9 (95 per cent c.i. 93·5 to 96·3) and 92·9 (91·7 to 94·1) per cent respectively. Inferences remained unchanged following propensity score analysis (hazard ratio for BCS versus mastectomy: 0·81, 95 per cent c.i. 0·64 to 1·03). Conclusion:The prevalence of young women with breast cancer treated by mastectomy remains high in Asian countries. Patients treated with BCS appear to survive as well as those undergoing mastectomy.

Project description:Introduction: The early randomized controlled trials revealed no differences in survival between breast-conserving surgery (BCS) and mastectomy. However, breast cancer treatment has undergone changes, and the results of recent population-based registry studies suggest superior long-term survival after BCS. To explore the current evidence, a systematic review and meta-ana lysis of population-based observational studies from 2010 and onward was conducted. Methods: A literature search was conducted in the PubMed, Embase, and Cochrane databases to identify relevant literature. Keywords included “mastectomy,” “breast conserving surgery,” and “survival.” The identified studies were narratively reviewed and effect sizes (hazard ratios [HRs]) for overall (OS) and breast cancer-specific survival (BCSS) were combined with random-effects models. Results: A total of 30 reports were included in the review, and results from 25 studies were included in the meta-analyses. Compared with mastectomy, BCS was associated with better OS (HR = 1.34 [1.20–1.51]; N = 1,311,600) and BCSS (HR = 1.38 [1.29–1.47]; N = 494,267). Selected subgroups of patients, based on lymph node status, age (<50 years/≥50 years), and radiation therapy after mastectomy (±), all showed better overall survival after BCS. The number (range 4–12) and type of prognostic variables adjusted for in the survival analyses of the studies did not statistically significantly moderate the differences in survival between BCS and mastectomy. Conclusions: The combined findings from large population-based studies indicate that BCS is associated with survival benefit compared with mastectomy, suggesting that BCS be the recommended treatment of early breast cancer (T1-2N0-1M0) if a radical lumpectomy can be performed. Mini-Abstract: A systematic review and meta-analysis of population-based observational studies comparing the survival after breast-conserving surgery and mastectomy in patients with breast cancer. The review comprises 30 papers from 2010 to 2021. More than 1.3 million patients are included in the meta-analyses.

Project description:PurposeRecent observations regarding long-term outcomes among patients with early-stage breast cancer (BC) who underwent breast-conserving surgery (BCS) plus whole-breast irradiation (WBI) or mastectomy are from a small number of registry-based studies. Therefore, these findings may overestimate differences in survival between the two groups, compared with randomized controlled trials conducted in the 1980s. The aim of this study is to compare long-term outcomes and clinicopathologic characteristics between patients treated with BCS + WBI or mastectomy for BC.MethodsWe performed a propensity score-matched analysis in a cohort of 9710 patients aged < 70 years who underwent BCS + WBI or mastectomy without external radiotherapy for a first primary BC (pT1-2, N0-3a) at the European Institute of Oncology between 2000 and 2008. Patients were matched by propensity score.ResultsMedian follow-up was 8.4 years (interquartile range 6.5-10.2). The cumulative incidence of axillary lymph node recurrence at 10 years was lower in the BCS + WBI group [2.4% (95% CI, 1.7-3.3%)] than in the mastectomy group [4.4% (95% CI, 3.5-5.5%)] (P = .0005), and the cumulative incidence of contralateral BC was higher in the BCS + WBI group [3.9% (95% CI, 2.8-5.1%)] than in the mastectomy group [2.5% (95% CI, 1.7-3.4%)] (P = .01). Among the 366 patients with HER2 subtype BC, BCS + WBI was associated with a fivefold higher risk [hazard ratio 4.97 (95% CI, 2.28-10.8)] of ipsilateral breast tumor recurrence (IBTR), compared with mastectomy (P < .0001); however, among patients with other BC subtypes, the rates of IBTR were not statistically significantly different.ConclusionPatients with HER2 subtype BC (T1-2, N0-3) who underwent BCS + WBI had a statistically significantly higher risk of IBTR than patients who underwent mastectomy. Survival was not statistically significantly different between the groups.

Project description:BackgroundMetaplastic breast cancer (MBC) are rare. The survival outcomes of MBC patients after breast conserving surgery plus radiotherapy (BCS+RT) or mastectomy have not been established. The study aimed to compare survival outcomes of MBC patients subjected to BCS+RT or mastectomy therapeutic options.MethodsPatients who were subjected to BCS+RT or mastectomy between 2004 and 2014 were enrolled in this study through the Surveillance, Epidemiology and End Results (SEER) database. Breast cancer-specific survival (BCSS) and the overall survival (OS) of the participants were determined. Cox proportional hazard model and the Kaplan Meier method were used to determine the correlation between the two surgical methods and survival outcomes.ResultsA total of 1197 patients were enrolled in this study. Among them, 439 patients were subjected to BCS+RT, while 758 patients were subjected to mastectomy. After propensity score matching (PSM), the BCS+RT and mastectomy groups consisted of 321 patients, respectively. The univariate and multivariate analysis with a 6-month landmark all indicate that patients receiving BCS+RT has higher OS than patients receiving mastectomy (HR = 0.701,95% CI = 0.496-0.990, P = 0.044; HR = 0.684,95% CI = 0.479-0.977, P = 0.037) while the BCSS was no difference between the two groups (HR = 0.739,95% CI = 0.474-1.153, P = 0.183; HR = 0.741,95% CI = 0.468-1.173, P = 0.200).ConclusionThe BCS+RT therapeutic option exhibits a higher OS in MBC patients compared to the mastectomy approach.

Project description:Ductal carcinoma in situ with microinvasion (DCIS-MI) is a subtype of breast cancer with a good prognosis, for which both breast conserving surgery plus radiotherapy (BCS + RT) and mastectomy are feasible surgical methods, but no clear conclusion has been made on the choice of these treatments. We used the Surveillance, Epidemiology and End Results database to extract 5432 DCIS-MI patients. Participants were divided into the BCS + RT group and the mastectomy group. We compared the overall survival (OS) and breast cancer-specific survival (BCSS) of the two groups using the Kaplan-Meier method and Cox regressions before and after propensity score matching (PSM). Before PSM, both univariate and multivariate analyses showed that BCS + RT group had significantly higher OS and BCSS compared with patients in the mastectomy group (P < 0.001). After PSM, the multivariate analysis showed that compared with mastectomy, the BCS + RT showed significantly higher OS and BCSS (HR = 0.676, 95% CI = 0.540-0.847, P < 0.001; HR = 0.565,95% CI = 0.354-0.903, P = 0.017). In addition, the subgroup analysis showed that BCS + RT is at least equivalent to mastectomy with respect to OS and BCSS in any subgroup. For patients with DCIS-MI, the prognosis of BCS + RT was superior to mastectomy.
