Abstract
BACKGROUND Oncology databases that integrate genomic and clinical data have become valuable resources for precision medicine. However, the generalizability of these databases has not been comprehensively assessed. OBJECTIVES To describe the demographics, clinical characteristics, treatments, and overall survival of breast cancer cohorts in GENIE-BPC and three other databases. METHODS This study utilized GENIE-BPC, SEER, SEER-Medicare, and Merative MarketScan Research Databases. Women with invasive breast cancer were identified through EHR, cancer registries or ICD-9/10-CM codes. The ages were 18+ years or per database requirement. Treatments were based on EHR or HCPCS/NDC codes in claims. Overall survival was estimated as time from diagnosis to death. RESULTS Of female breast cancer patients in GENIE-BPC (n = 775), SEER (n = 548 336), SEER-Medicare (n = 68 914), and Marketscan (n = 109 499) databases, the median ages at initial diagnosis were 44, 62, 74, and 57 years, respectively. A greater proportion of patients in GENIE-BPC, compared to SEER/SEER-Medicare, had higher nuclear grades (%III-%IV: 57% vs. 26%/24%), advanced disease stage (%IV: 25.3% vs. 5%/3.6%), percent of triple negative breast cancer (19.7% vs. 10.2%/8.5%), and receipt of chemotherapy (85.0% vs. NA/22.3%). The 1-, 3-, and 5-year overall survival rates were lower in GENIE-BPC (78.5%, 60.5%, 55.5%) than in SEER (95.8%, 89.5%, 85.5%) and SEER-Medicare (91.6%, 81.4%, 75.0%). CONCLUSION Breast cancer patients in GENIE-BPC were younger, had more advanced disease, had a higher proportion of triple negative breast cancer and recipients of chemotherapy, and had poorer overall survival. Researchers must use statistical adjustment when extrapolating results (e.g., biomarker prevalence) from GENIE-BPC to the larger breast cancer population.

Vangsness KL, Juste J, Sam AP, Munabi N, Chu M, Agko M, Chang J, Carre AL. Post-Mastectomy Breast Reconstruction Disparities: A Systematic Review of Sociodemographic and Economic Barriers. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:1169. [PMID: 39064597 PMCID: PMC11279340 DOI: 10.3390/medicina60071169] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 05/31/2024] [Revised: 06/19/2024] [Accepted: 07/04/2024] [Indexed: 07/28/2024]
Abstract
Background: Breast reconstruction (BR) following mastectomy is a well-established beneficial medical intervention for patient physical and psychological well-being. Previous studies have emphasized BR as the gold standard of care for breast cancer patients requiring surgery. Multiple policies have improved BR access, but there remain social, economic, and geographical barriers to receiving reconstruction. Threats to equitable healthcare for all breast cancer patients in America persist despite growing awareness and efforts to negate these disparities. While race/ethnicity has been correlated with differences in BR rates and outcomes, ongoing research outlines a multitude of issues underlying this variance. Understanding the current and continuous barriers will help to address and overcome gaps in access. Methods: A systematic review assessing three reference databases (PubMed, Web of Science, and Ovid Medline) was carried out in accordance with PRISMA 2020 guidelines. A keyword search was conducted on 3 February 2024, specifying results between 2004 and 2024. Studies were included based on content, peer-reviewed status, and publication type. Two independent reviewers screened results based on title/abstract appropriateness and relevance. Data were extracted, cached in an online reference collection, and input into a cloud-based database for analysis. Results: In total, 1756 references were populated from all databases (PubMed = 829, Ovid Medline = 594, and Web of Science = 333), and 461 duplicate records were removed, along with 1147 results deemed ineligible by study criteria. Then, 45 international or non-English results were excluded. The screening sample consisted of 103 publications. After screening, the systematic review produced 70 studies with satisfactory relevance to our study focus. Conclusions: Federal mandates have improved access to women undergoing postmastectomy BR, particularly for younger, White, privately insured, urban-located patients. Recently published studies had a stronger focus on disparities, particularly among races, and show continued disadvantages for minorities, lower-income, rural-community, and public insurance payers. The research remains limited beyond commonly reported metrics of disparity and lacks examination of additional contributing factors. Future investigations should elucidate the effect of these factors and propose measures to eliminate barriers to access to BR for all patients.

The Impact of Travel Distance and Income on Breast Reconstruction after Mastectomy in a Rural Population. Plast Reconstr Surg Glob Open 2023; 11:e4802. [PMID: 36751509 PMCID: PMC9894339 DOI: 10.1097/gox.0000000000004802] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/30/2022] [Accepted: 12/14/2022] [Indexed: 02/05/2023]
Abstract
Factors that influence breast reconstruction after mastectomy have been previously examined in national databases. The purpose of this study was to determine the impact of patient travel distance and income on breast reconstruction after mastectomy in a rural population. Methods Retrospective review of mastectomy patients from 2017 to 2021 was performed from our prospectively enrolled tumor registry. Analysis included frequencies and percentages, descriptive statistics, χ 2 analysis, independent sample t tests, and multivariable analysis. Results In total, 462 patients were included. Median BMI was 27.6 kg/m2, 96.1% of patients were White, and median age at diagnosis was 60.0 years. Reconstruction rate was 52.6%, and median length of follow-up was 24.6 months. No significant difference was found in the distance traveled by patients who underwent reconstruction (16.6 versus 16.7 miles; P = 0.94). Rates of reconstruction in patients who traveled 0-10 miles, 11-30 miles, and over 30 miles did not differ significantly (P = 0.16). Median household income was significantly different in reconstructed and nonreconstructed patients ($55,316.00 versus $51,629.00; P = 0.047). Rates of reconstruction were significantly higher in patients with median household income greater than $65,000 (P = 0.024). This difference was not significant on multivariable analysis. Conclusions Travel distance did not significantly impact reconstruction rates after mastectomy, while household income did on univariable analysis. Studies at an institutional or regional level remain valuable, especially in populations that may not be accurately represented in larger database studies. Our findings highlight the importance of patient education, resource allocation, and multidisciplinary approach to breast cancer care, especially in the rural setting.

Abstract
BACKGROUND This study aimed to determine benefits of the Enhanced Recovery After Surgery (ERAS) pathway implementation in free flap breast reconstruction related to postoperative narcotic use and health care resource utilization. METHODS A retrospective analysis of consecutive patients undergoing deep inferior epigastric perforator flap breast reconstruction from November of 2015 to April of 2018 was performed before and after implementation of the ERAS protocol. RESULTS Four hundred nine patients met inclusion criteria. The pre-ERAS group comprised 205 patients, and 204 patients were managed through the ERAS pathway. Mean age, laterality, timing of reconstruction, and number of previous abdominal surgical procedures were similar ( p > 0.05) between groups. Mean operative time between both groups (450.1 ± 92.7 minutes versus 440.7 ± 93.5 minutes) and complications were similar ( p > 0.05). Mean intraoperative (58.9 ± 32.5 versus 31.7 ± 23.4) and postoperative (129.5 ± 80.1 versus 90 ± 93.9) morphine milligram equivalents used were significantly ( p < 0.001) higher in the pre-ERAS group. Mean length of stay was significantly ( p < 0.001) longer in the pre-ERAS group (4.5 ± 0.8 days versus 3.2 ± 0.6 days). Bivariate linear regression analysis demonstrated that operative time was positively associated with total narcotic requirements ( p < 0.001) and length of stay ( p < 0.001). CONCLUSIONS ERAS pathways in microsurgical breast reconstruction promote reduction in intraoperative and postoperative narcotic utilization with concomitant decrease in hospital length of stay. In this study, patients managed through ERAS pathways required 46 percent less intraoperative and 31 percent less postoperative narcotics and had a 29 percent reduction in hospital length of stay.

Higher Risk of Depression After Total Mastectomy Versus Breast Reconstruction Among Adult Women With Breast Cancer: A Systematic Review and Metaregression. Clin Breast Cancer 2021; 21:e526-e538. [PMID: 33541834 DOI: 10.1016/j.clbc.2021.01.003] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/28/2020] [Revised: 11/03/2020] [Accepted: 01/05/2021] [Indexed: 12/24/2022]
Abstract
This systematic review with a meta-regression was conducted to determine the risk of depression after mastectomy compared to breast reconstruction among women with breast cancer 1 year after surgery. A literature search was conducted according to PRISMA guidelines using 4 databases: Medline (Ovid), Embase, Cinahl, and the Cochrane Library for the period January 2000 to March 2019. Studies that measured the status of depression within 1 year and immediately after surgery were included. Outcomes related to depression were analyzed by using a pool of event rates and a risk ratio of 95% confidence interval (CI), P value, and a fitting model based on the results of a heterogeneity test of mastectomy and BR. The statistical analysis was conducted using Comprehensive Meta-analysis 3.0 software. Nine studies met the inclusion criteria. There were 865 cases of mastectomy only, with a 22.2% risk of depression (95% CI, 12.4-36.2). In 869 women who underwent BR, the risk of depression was 15.7% (95% CI, 8.8-26.2). The depression risk ratio for mastectomy compared to BR was 1.36 (95% CI, 1.11-1.65). Patients with delayed reconstruction exhibited lower levels of depression (risk ratio 0.96, 95% CI 0.57-1.01). The Beck Depression Inventory (BDI) scale showed high sensitivity, and the Hospital Anxiety Depression Scale (HADS) with a cutoff of > 7 could measure even low to moderate depressive symptoms. One in 4 women with breast cancer had symptoms of depression after mastectomy; both surgeries were associated with depression in women 1 year after surgery. Our results will permit the development of proactive treatment plans before and after surgery to mitigate risk and prevent depression through the use of sensitive depression scales like BDI.
