Prospective study of pain outcomes associated with contralateral prophylactic mastectomy in women with nonhereditary breast cancer.

6587 Background: Women with nonhereditary breast cancer are increasingly undergoing contralateral prophylactic mastectomy (CPM). We examined pain severity and the impact of pain on the lives of women who underwent CPM compared to those who did not. We also examined the associations between age, race/ethnicity, reconstruction and pain outcomes. Methods: Between 2012 and 2015, we recruited women with newly diagnosed nonhereditary breast cancer who were planned for surgery. We assessed pain with the Brief Pain Inventory at initial surgical consultation and at 1, 6, 12, and 18 months after surgery. The repeated measures model was used to assess the association between pain severity or interference and CPM status over different time points adjusting for other covariates. Results: Of 288 women enrolled (mean age 56 years, 58% non-Hispanic White, 17% non-Hispanic Black), 50 underwent CPM, 163 had unilateral mastectomy, and 75 had breast conserving surgery. Mean pain severity was higher at 1 month (2.78 vs 1.9, p = .01) and 6 months (2.79 vs 1.96, p = .03) after surgery in women with CPM versus those without. In the multivariable repeated measures model adjusted for time, age, race/ethnicity and reconstruction status, there was a significant interaction between time and CPM for pain severity (p < .01) but not interference (p = .13). This suggests that CPM patients had higher pain severity in the first 6 months after surgery, but their pain scores decreased by 12 months becoming similar to women without CPM. Black women had higher pain severity (mean difference 1.35, standard error [SE] 0.35; p < .01) and interference (mean difference 0.91, SE 0.32; p < .01) compared to White women with or without CPM. There was no association between age or reconstruction status and pain severity or interference. Conclusions: Pain severity in patients undergoing CPM is highest during the first 6 months after surgery. Women considering CPM should be counseled about this potential outcome. Race/ethnic disparities exist in pain management, pain perceptions and communication of pain. Black women undergoing breast surgery report worse pain outcomes than White women regardless of CPM status.

PURPOSE: We sought to examine tumor subtype, stage at diagnosis, time to surgery (TTS), and overall survival (OS) among Hispanic patients of different races and among Hispanic and non-Hispanic (NH) women of the same race. METHODS: Women 18 years of age or older who had been diagnosed with stage 0-IV breast cancer and who had undergone lumpectomy or mastectomy were identified in the National Cancer Database (2004-2014). Tumor subtype and stage at diagnosis were compared by race/ethnicity. Multivariable linear regression and Cox proportional hazards modeling were used to estimate associations between race/ethnicity and adjusted TTS and OS, respectively. RESULTS: A total of 44,374 Hispanic (American Indian [AI]: 79 [0.2%]; Black: 1,011 [2.3%]; White: 41,126 [92.7%]; Other: 2,158 [4.9%]) and 858,634 NH women (AI: 2,319 [0.3%]; Black: 97,206 [11.3%]; White: 727,270 [84.7%]; Other: 31,839 [3.7%]) were included. Hispanic Black women had lower rates of triple-negative disease (16.2%) than did NH Black women (23.5%) but higher rates than did Hispanic White women (13.9%; P < .001). Hispanic White women had higher rates of node-positive disease (23.2%) versus NH White women (14.4%) but slightly lower rates than Hispanic (24.6%) and NH Black women (24.5%; P < .001). Hispanic White women had longer TTS versus NH White women regardless of treatment sequence (adjusted means: adjuvant chemotherapy, 42.71 v 38.60 days; neoadjuvant chemotherapy, 208.55 v 201.14 days; both P < .001), but there were no significant racial differences in TTS among Hispanic patients. After adjustment, Hispanic White women (hazard ratio, 0.77 [95% CI, 0.74 to 0.81]) and Black women (hazard ratio, 0.75 [95% CI, 0.58 to 0.96]) had improved OS versus NH White women (reference) and Black women (hazard ratio, 1.15 [95% CI, 1.12 to 1.18]; all P < .05). CONCLUSION: Hispanic women had improved OS versus NH women, but racial differences in tumor subtype and nodal stage among Hispanic women highlight the importance of disaggregating racial/ethnic data in breast cancer research.

Purpose The incidence of contralateral prophylactic mastectomy (CPM) has continued to increase. We prospectively examined psychosocial outcomes before and up to 18 months after surgery in women who did or did not have CPM. Methods Women with unilateral, nonhereditary breast cancer completed questionnaires before and 1, 6, 12, and 18 months after surgery. Primary psychosocial measures were cancer worry and cancer-specific distress. Secondary measures were body image, quality of life (QOL), decisional satisfaction, and decisional regret. Results A total of 288 women (mean age, 56 years; 58% non-Hispanic white) provided questionnaire data, of whom 50 underwent CPM. Before surgery, women who subsequently received CPM had higher cancer distress ( P = .04), cancer worry ( P < .001), and body image concerns ( P < .001) than women who did not have CPM. In a multivariable repeated measures model adjusted for time, age, race/ethnicity, and stage, CPM was associated with more body image distress ( P < .001) and poorer QOL ( P = .02). There was a significant interaction between time point and CPM group for cancer worry ( Pinteraction < .001), suggesting that CPM patients had higher presurgery cancer worry, but their postsurgery worry decreased over time and was similar to the worry of patients who did not have CPM. QOL was similar between CPM groups before surgery but declined 1 month after surgery and remained lower than patients who did not have CPM after surgery ( Pinteraction = .05). Conclusion These results may facilitate informed discussions between women and their physicians regarding CPM. Fear and worry may be foremost concerns at the time surgical decisions are made, when women may not anticipate the adverse future effect of CPM on body image and QOL.

AbstractObjectiveTo determine if blood levels of 25-hydroxyvitamin D (25-D) or its active metabolite, 1,25-dihydroxyvitamin D (1,25-D), are lower in women at the time of first diagnosis of breast cancer than in comparable women without breast cancer.DesignThis was a clinic-based case–control study with controls frequency-matched to cases on race, age, clinic and month of blood drawing.SettingUniversity-based breast referral clinics.SubjectsOne hundred and fifty-six women with histologically documented adenocarcinoma of the breast and 184 breast clinic controls.ResultsThere were significant mean differences in 1,25-D levels (pmol ml−1) between breast cancer cases and controls; white cases had lower 1,25-D levels than white controls (mean difference ± SE: −11.08 ± 0.76), and black cases had higher 1,25-D levels than black controls (mean difference ± SE: 4.54 ± 2.14), although the number of black women in the study was small. After adjustment for age, assay batch, month of blood draw, clinic and sample storage time, the odds ratio (95% confidence interval, CI) for lowest relative to highest quartile was 5.2 (95% CI 2.1, 12.8) for white cases and controls. The association in white women was stronger in women above the median age of 54 than in younger women, 4.7 (95% CI 2.1, 10.2) vs. 1.5 (95% CI 0.7, 3.0). There were no case–control differences in 25-D levels in either group.ConclusionsThese data are consistent with a protective effect of 1,25-D for breast cancer in white women.

1084 Background: Black women diagnosed with breast cancer are more likely to have a poor prognosis, regardless of breast cancer subtype. Despite having a lower incidence rate of breast cancer when compared to white women, black women have the highest breast cancer death rate of all racial and ethnic groups, a characteristic often attributed to late stage at diagnosis. Distant metastases are considered the leading cause of death from breast cancer. We performed a follow up study of women with breast cancer in the Mount Sinai Health System (MSHS) to determine differences in distant metastases rates among black versus white women. Methods: Women were initially recruited as part of an NIH funded cross-sectional study from 2013-2020 to examine the link between insulin resistance (IR) and breast cancer prognosis. Women self-identified as black or white race. Data was collected via retrospective analysis of electronic medical records (EMR) between September 2020-January 2021. Distant metastases at diagnosis was defined as evidence of metastases in a secondary organ (not lymph node). Stage at diagnosis was recorded for all patients. Distant metastases after diagnosis was defined as evidence of metastases at any time after initiation of treatment. Univariate analysis was performed using Fisher’s exact test, multivariate analysis was performed by binary logistic regression, and results expressed as odds ratio (OR) and 95% confidence interval (CI). A p value <0.05 was considered statistically significant. Results: We identified 441 women enrolled in the IR study within the MSHS (340 white women, 101 black women). Median follow up time for all women was 2.95 years (median = 3.12 years for white and 2.51 years for black women (p=0.017)). Among these patients, 11 developed distant metastases after diagnosis: 4 (1.2%) white and 7 (6.9%) black (p=0.004). Multivariate analysis adjusting for age, race and stage at diagnosis revealed that black women were more likely to have distant metastasis (OR 5.8, CI 1.3-25.2), as were younger women (OR for age (years) 0.9, CI 0.9-1.0), and those with more advanced stage at diagnosis. Conclusions: Black women demonstrated a far higher percentage of distant metastases after diagnosis even when accounting for age and stage. These findings suggest that racial disparities still exist in the development of distant metastases, independent from a late-stage diagnosis. The source of existing disparities needs to be further understood and may be found in surveillance, treatment differences, or follow up.

e12599 Background: Higher prevalence of triple negative breast cancer (TNBC) in black women with associated poor outcomes due to various disparities is well documented within a single state. We examine multiple states to better understand the state effect on such differences in incidence and prevalence of TNBC in black women. Methods: Female patients of ages 19 years old and above with breast cancer from the Surveillance, Epidemiology and End Results (SEER) Program across 13 states (608 counties) from 2015 (n = 66,444) and 2016 (n = 66,122) were examined. The relationships between the proportion of black and white women and the rate of patients with different tumor subtypes (luminal A, luminal B, HR-HER2+, and triple negative) were examined at the county level using ordinary least-square regression models. In parallel, due to consideration of various state-specific healthcare policies, socio-cultural norms, and socio-economic disparities, multi-level regression models were applied to examine the nested, random effect of each state on TNBC prevalence in each county. Bonferroni correction was applied to reduce the Type I error caused by repeated use of the same variables in multiple tests. Results: The baseline breast cancer rates between black and white women were similar in the population (0.171% for black and 0.168% for white). Consistent to previous studies, we demonstrate a significant positive correlation (p < 0.001) in TNBC in black females in both years. Surprisingly, when accounted for the random effects on states, 38.2% (2015) and 34.3% (2016) increase in incidence of TNBC in black females were seen, suggestive of state-specific disparity affecting race-specific health. In 2015, other subtypes of breast cancer in both black and white females did not result in significant relationship. Interestingly, in 2016, there was a significant relationship seen between the TNBC rate in white females and the white female population rate only after adjusting for the state effect (p = 0.026). This indicates the impact of non-biological factors such as state-wide health policies. Additionally, HR-HER2+ black females had a significant relationship against respective population rate only after adjusting for the state effect as well (p = 0.0394). For luminal A white females, a 15% decrease in incidence was seen after adjusting for state effect (p = 0.0424). Conclusions: This is the first known across-state examination of breast cancer subtypes by race with random effects on state. This study shows the role of state-specific factors affecting incidence in black and white females and potentially indicates the importance of state-level management for breast cancer on health disparities in addition to race-driven effects. Further studies are needed to elucidate comparable differences between states affecting the rates of various subtypes of breast cancer and thus health outcomes.

Objective: After chemotherapy for breast cancer, Black women gain more weight and have an increased mortality rate compared with White women. Our study objective was to compare biomarkers associated with obesity in Black women with and without a history of breast cancer.Design: Case-controlSetting: Academic/federal institutionParticipants: Black women with a history of breast cancer (cases) and age-matched controls.Methods: We compared insulin resistance, inflammation, and lipids in overweight and obese Black women with a history of breast cancer (n=19), age similar controls (n=25), and older controls (n=32). Groups did not differ on mean body mass index (BMI), which was 35.4 kg/m2, 36.0 kg/m2, and 33.0 kg/m2, respectively.Main Outcome Measures: Insulin resistance (HOMA-IR); inflammation (TNF-α, IL-1b, IL-6, IL-8, CRP); lipids (cholesterol, triglycerides).Results: Cases had 1.6 and 1.38 times higher HOMA-IR values compared with age similar and older controls, respectively (P≤.001 for both). TNF-α and IL-1b were significantly higher in cases compared with both control groups (P<.001 for both). IL-6 was also higher in cases compared with age-similar controls (P=.007), and IL-8 was lower in cases compared with older controls (P<.05). Lipids did not differ between cases and either control group.Conclusions: Black women with breast cancer were significantly more insulin resistant with increased inflammation compared not only with age similar controls but with women who were, on average, a decade older. These biomarkers of insulin resistance and inflammation may be associated with increased risk of breast cancer recurrence and require ongoing evaluation, especially given the relatively abnormal findings compared with the controls in this underserved group.

Objective Racial and ethnic disparities in obstetric care and delivery outcomes have shown that black women experience high rates of pregnancy-related mortality and morbidity, along with high rates of cesarean delivery, compared with other racial and ethnic groups. We aimed to quantify these disparities and test the effects of race/ethnicity in stratified statistical models by insurance payer and socioeconomic status, adjusting for comorbidities specific to an obstetric population. Study Design We analyzed maternal outcomes in a sample of 6,872,588 delivery records from California, Florida, Kentucky, Maryland, and New York from 2007 to 2014 from the State Inpatient Databases, Healthcare Cost and Utilization Project. We compared present-on-admission characteristics of parturients by race/ethnicity, and estimated logistic regression and generalized linear models to assess outcomes of in-hospital mortality, cesarean delivery, and length of stay. Results Compared with white women, black women were more likely to die in-hospital (odds ratio [OR]: 1.90, 95% confidence interval [CI]: 1.47–2.45) and have a longer average length of stay (incidence rate ratio: 1.10, 95% CI: 1.09–1.10). Black women also were more likely to have a cesarean delivery (OR: 1.12, 95% CI 1.12–1.13) than white women. These results largely held in stratified analyses. Conclusion In most insurance payers and socioeconomic strata, race/ethnicity alone is a factor that predicts parturient outcomes.
