Variations in breast cancer surgical treatment and timing: determinants and disparities.

ABSTRACT:

Purpose

To describe clinical and non-clinical factors associated with receipt of breast conserving surgery (BCS) versus mastectomy and time to surgical intervention.

Methods

Cross-sectional retrospective study of January 1, 2012 through March 31, 2018 data from the IBM MarketScan Commercial Claims and Encounter and Medicare Supplemental Databases. Area Health Resource Files provided non-clinical characteristics and sociodemographic data. Eligibility: Female sex, claim(s) with ICD-9-CM or ICD-10-CM diagnosis of non-metastatic invasive breast cancer, > 6 months of continuous insurance pre- and post-diagnosis, evidence of BCS or mastectomy following initial ICD9/10 code diagnosis. Logistic and quantile multivariable regression models assessed the association between clinical and non-clinical factors and the outcome of BCS and time to surgery, respectively.

Results

A total of 53,060 women were included in the study. Compared to mastectomy, BCS was significantly associated with older age (ORs: 1.54 to 2.99, 95% CIs 1.45 to 3.38; ps < .0001) and higher community density of medical genetics (OR: 5.88, 95% CIs 1.38 to 25.00; p = 0.02) or obstetrics and gynecology (OR: 1.13, 95% CI 1.02 to 1.25; p = .02) physicians. Shorter time-to-BCS was associated with living in the South (-2.96, 95% CI -4.39 to -1.33; p < .0001). Longer time-to-BCS was associated with residence in more urban (4.18, 95% CI 0.08 to 8.29; p = 0. 05), educated (9.02, 95% CI 0.13 to 17.91; p = 0.05), or plastic-surgeon-dense (4.62, 95% CI 0.50 to 8.73; p = 0.03) communities.

Conclusions

Clinical and non-clinical factors are associated with adoption of BCS and time to treatment, suggesting opportunities to ensure equitable and timely care.

Project description:Mitochondria, which are multi-functional, have been implicated in cancer initiation, progression, and metastasis due to metabolic alterations in transformed cells. Mitochondria are involved in the generation of energy, cell growth and differentiation, cellular signaling, cell cycle control, and cell death. To date, the mitochondrial basis of cancer disparities is unknown. The goal of this review is to provide an understanding and a framework of mitochondrial determinants that may contribute to cancer disparities in racially different populations. Due to maternal inheritance and ethnic-based diversity, the mitochondrial genome (mtDNA) contributes to inherited racial disparities. In people of African ancestry, several germline, population-specific haplotype variants in mtDNA as well as depletion of mtDNA have been linked to cancer predisposition and cancer disparities. Indeed, depletion of mtDNA and mutations in mtDNA or nuclear genome (nDNA)-encoded mitochondrial proteins lead to mitochondrial dysfunction and promote resistance to apoptosis, the epithelial-to-mesenchymal transition, and metastatic disease, all of which can contribute to cancer disparity and tumor aggressiveness related to racial disparities. Ethnic differences at the level of expression or genetic variations in nDNA encoding the mitochondrial proteome, including mitochondria-localized mtDNA replication and repair proteins, miRNA, transcription factors, kinases and phosphatases, and tumor suppressors and oncogenes may underlie susceptibility to high-risk and aggressive cancers found in African population and other ethnicities. The mitochondrial retrograde signaling that alters the expression profile of nuclear genes in response to dysfunctional mitochondria is a mechanism for tumorigenesis. In ethnic populations, differences in mitochondrial function may alter the cross talk between mitochondria and the nucleus at epigenetic and genetic levels, which can also contribute to cancer health disparities. Targeting mitochondrial determinants and mitochondrial retrograde signaling could provide a promising strategy for the development of selective anticancer therapy for dealing with cancer disparities. Further, agents that restore mitochondrial function to optimal levels should permit sensitivity to anticancer agents for the treatment of aggressive tumors that occur in racially diverse populations and hence help in reducing racial disparities.

Project description:BackgroundBlack/African American women with breast cancer have a disproportionately higher risk of mortality compared to other race groups, although their overall incidence of disease is lower. Despite this, advance care planning (ACP) and consequent code status documentation remain low in this vulnerable patient population. Code status orders (i.e., Full code, Do Not Attempt Resuscitation [DNAR], Do Not Intubate [DNI]) allow consideration of patient preferences regarding the use of aggressive treatments, such as cardiopulmonary resuscitation and intubation. The aim of this study is to characterize presence of code status orders and determine whether race affects code status documentation after the first encounter for breast cancer.MethodsData were derived from 7524 women with breast cancer from the University of Chicago Medical Center (UCMC) between 2016 and 2021. Cox regression was used to estimate the effects of race and adjusted for age, ethnicity, inpatient stays, metastatic breast cancer, marital status, and body mass index.ResultsThe sample included 60.5% White, 3.6% Asian/Mideast Indian, 28.9% Black/African American, and 7.0% other or unknown race. Results indicate that code status orders after the first breast cancer encounter were uncommon (7.2%). Black/African American race (HR = 2.74; 95% CI: 1.75, 4.28) emerged as a significant factor associated with any code status orders compared to other race groups even when adjusting for covariates.ConclusionsCode status documentation in this sample of women with breast cancer was low overall, yet rates were higher among Black/African American patients compared to other race groups. In fact, race remains a significant predictor of code status documentation even when accounting for indirect measures of cancer severity. This could be denoting the racial disparities (e.g., higher cancer malignancy such as triple negative breast cancer) in breast cancer mortality risk. Future research is needed to identify factors unique to Black/African American women that would increase code status documentation so that goal concordant care can be prioritized among patients with breast cancer.
