Early Stage Breast Cancer: Does Histologic Subtype (Ductal vs. Lobular) Impact 5 Year Overall Survival? Cancers (Basel) 2024; 16:1509. [PMID: 38672591 PMCID: PMC11049226 DOI: 10.3390/cancers16081509] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/05/2024] [Revised: 04/03/2024] [Accepted: 04/12/2024] [Indexed: 04/28/2024] Open
Abstract
Histology is an important predictor of the behavior of breast cancer. We aim to study the impact of histology on the overall survival (OS) of breast cancer patients. We studied 11,085 breast cancer patients diagnosed with T1-T2 tumors, clinically node-negative and non-metastatic, from 2004 to 2019 included in the National Cancer Database. Kaplan-Meier curves, log-rank tests and Cox regression models were used to study the impact of histology and other variables on OS. In our patient population, 8678 (78.28%) had ductal cancer (IDC), while 2407 (21.71%) had lobular cancer (ILC). ILC patients were significantly more likely to be older, Caucasian, have a lower grade at diagnosis and be hormone receptor-positive compared to IDC patients. There was no statistically significant difference in the 5-year OS of early stage ductal (16.8%) and lobular cancer patients (16.7%) (p = 0.200). Patients of Hispanic and African American origin had worse OS rates compared to non-Hispanic and Caucasian patients, respectively. For node-positive disease, HER2+ tumors and triple-negative tumors, chemotherapy had a positive influence on OS (HR 0.85, 95% CI 0.77-0.93, p = 0.0012). Histology did not have a significant impact on the 5-year OS of early stage breast cancer patients.

Abstract
Breast surgery is the cornerstone of treatment for early breast cancer. Historically, mastectomy and conventional breast-conserving surgery (BCS) were the main surgical techniques for treatment. Now, oncoplastic breast surgery (OBS), introduced in the 1990s, allows for a combination of BCS and reconstructive surgery to excise the cancer while preserving or enhancing the contour of the breast, leading to improved aesthetic results. Although imaging after conventional lumpectomy demonstrates typical postsurgical changes with known evolution patterns over time, OBS procedures show postsurgical changes/fat necrosis in locations other than the lumpectomy site. The purpose of this article is to familiarize radiologists with various types of surgical techniques for removal of breast cancer and to distinguish benign postoperative imaging findings from suspicious findings that warrant further work-up.

Abstract
Minoritized groups including Latinos are less engaged in awareness and discussion of advance care planning (ACP) due to the United States English-dominated healthcare system that contributes to systemic inequities related to language and cultural barriers. Explicit interventions, such as a sole Spanish-speaking educational session, may begin discussions of ACP among Latina breast cancer survivors. However, what constitutes a culturally sensitive Spanish-language ACP educational session is currently unknown. To address this need, this current project (1) presented a nurse-led ACP educational session and (2) held a focus group to assess the acceptability of the Spanish-focused ACP educational session to a Spanish-speaking group of Latina breast cancer survivors. Thematic analysis revealed four themes: (1) familial involvement, (2) need for advance care planning education, (3) addressing language and cultural barriers, and (4) culturally sensitive and informative resources. Features of a culturally sensitive Spanish-focused ACP educational session were identified and found to reduce current barriers that hinder ACP conversations in Latina breast cancer survivors.

Abstract
BACKGROUND Racial and ethnic disparities in guideline-recommended breast cancer treatment are well documented, however studies including diagnostic and staging procedures necessary to determine treatment indications are lacking. The purpose of this study was to characterize patterns in delivery of evidence-based services for the diagnosis, clinical workup, and first-line treatment of breast cancer by race-ethnicity. METHODS SEER-Medicare data were used to identify women diagnosed with invasive breast cancer between 2000 and 2017 at age 66 or older (n = 2,15,605). Evidence-based services included diagnostic procedures (diagnostic mammography and breast biopsy), clinical workup (stage and grade determination, lymph node biopsy, and HR and HER2 status determination), and treatment initiation (surgery, radiation, chemotherapy, hormone therapy, and HER2-targeted therapy). Poisson regression was used to estimate rate ratios (RR) and 95% confidence intervals (CI) for each service. RESULTS Black and American Indian/Alaska Native (AIAN) women had significantly lower rates of evidence-based care across the continuum from diagnostics through first-line treatment compared to non-Hispanic White (NHW) women. AIAN women had the lowest rates of HER2-targeted therapy and hormone therapy initiation. While Black women also had lower initiation of HER2-targeted therapy than NHW, differences in hormone therapy were not observed. CONCLUSIONS Our findings suggest patterns along the continuum of care from diagnostic procedures to treatment initiation may differ across race-ethnicity groups. IMPACT Efforts to improve delivery of guideline-concordant treatment and mitigate racial-ethnic disparities in healthcare and survival should include procedures performed as part of the diagnosis, clinical workup, and staging processes.

Abstract
Given that 20% to 40% of women who have percutaneous breast biopsy subsequently undergo breast surgery, knowledge of imaging women with a history of benign (including high-risk) disease or breast cancer is important. For women who had surgery for nonmalignant pathology, the surveillance recommendations are determined by their overall risk. Higher-than-average risk women with a history of benign surgery may require screening mammography starting at an earlier age before 40 and may benefit from screening MRI. For women with breast cancer who have undergone initial excision and have positive margins, imaging with diagnostic mammography or MRI can sometimes guide additional surgical planning. Women who have completed breast conservation therapy for cancer should get annual mammography and may benefit from the addition of MRI or ultrasound to their surveillance regimen. The ACR Appropriateness Criteria are evidence-based guidelines for specific clinical conditions that are reviewed annually by a multidisciplinary expert panel. The guideline development and revision process support the systematic analysis of the medical literature from peer reviewed journals. Established methodology principles such as Grading of Recommendations Assessment, Development, and Evaluation or GRADE are adapted to evaluate the evidence. The RAND/UCLA Appropriateness Method User Manual provides the methodology to determine the appropriateness of imaging and treatment procedures for specific clinical scenarios. In those instances in which peer reviewed literature is lacking or equivocal, experts may be the primary evidentiary source available to formulate a recommendation.

Abstract
BACKGROUND Increasing number of breast cancer survivors in the USA have led to greater focus on the long-term health outcomes and surveillance care among these women. However limited evidence exists of use of surveillance mammography among breast cancer survivors and how it varies across racial/ethnic groups. METHODS We conducted a systematic review of the literature to explore disparities in use of surveillance mammogram among women breast cancer survivors by searching for relevant studies published between 2000 and 2020 from Medline (Ovid), PubMed (National Library of Medicine), and PsycINFO (Ovid) bibliographic databases. Two authors independently screened titles, abstracts, and full texts of all articles that reported surveillance mammography use across racial/ethnic groups. Data on study design, screening eligibility, sample size, operational definition, and/or measure of the use of a surveillance mammogram among breast cancer survivors and the association between race/ethnicity and use of a surveillance mammogram were summarized in the evidence tables. RESULTS We identified 1544 records from the three databases, and 30 studies examined the use of surveillance mammograms among breast cancer survivors across race/ethnic groups. Of these, 21 provided adjusted estimates of racial/ethnic disparities in use of surveillance mammograms, and 15 of these reported statistically significant disparities. In summary, most studies reported that non-white women (mainly Blacks and Hispanics) were less likely to receive a timely surveillance mammogram compared to White. CONCLUSION This study extends the evidence of racial/ethnic disparities beyond completion of initial treatment by finding similar disparities in receipt of surveillance mammograms among breast cancer survivors. IMPLICATION FOR CANCER SURVIVORS Our findings identify a need to improve efforts to increase post-treatment use of surveillance mammography among racial/ethnic minority women to reduce these gaps and improve overall clinical and quality of life outcomes.

Abstract
In the United States, early detection methods have contributed to the reduction of overall breast cancer mortality but this pattern has not been observed uniformly across all racial groups. A vast body of research literature shows a set of health care, socio-economic, biological, physical, and behavioural factors influencing the mortality disparity. In this paper, we review the modelling frameworks, statistical tests, and databases used in understanding influential factors, and we discuss the factors documented in the modelling literature. Our findings suggest that disparities research relies on conventional modelling and statistical tools for quantitative analysis, and there exist opportunities to implement data-based modelling frameworks for (1) exploring mechanisms triggering disparities, (2) increasing the collection of behavioural data, and (3) monitoring factors associated with the mortality disparity across time.

Abstract
PURPOSE The aim of this study is to investigate if evidence-based clinical guidelines are implemented equitability among ethnic minority breast cancer patients using Medicare Advantage and investigate if presumed advantages of managed care over fee-for-service are greater for minorities than for Whites. METHODS Data from the Surveillance, Epidemiology, and End Results and Medicare were used to examine 70,755 women over age 65 diagnosed with early stage breast cancer between 2005 and 2009. Implementation of two clinical guidelines was assessed: receipt of radiation therapy after breast conserving surgery and estrogen receptor status documentation. Multilevel logistic regression and inverse propensity weighting controlled for confounding. RESULTS African Americans are still less likely than Whites to receive radiation therapy after breast-conserving surgery, whether they use Medicare fee-for-service (OR 95 % CI) = 0.90 (0.83, 0.98) or managed care (OR 95 % CI) = 0.87 (0.76, 1.00). Differences between receipt of radiation therapy by insurance plan type was nonexistent. Relative to FFS, the use of managed care improved the odds of having estrogen receptor status documented by 44 % in African Americans, (OR 95 % CI) = 1.44 (1.15, 1.83) and by 42 % in Latina patients (OR 95 % CI) = 1.42 (1.17, 1.78). CONCLUSIONS Compared to Medicare fee-for-service, ethnic and racial disparities among Medicare Advantage users were reduced. We observed fewer disparities, but not an elimination of disparities, among Medicare Advantage enrollees receiving breast cancer care with an organizational and patient component of care. This suggests managed care may still need to focus on minority patient empowerment and involvement in care.
