A prospective study of vitamin D, proinflammatory cytokines, and risk of fragility fractures in women on aromatase inhibitors for breast cancer.

Vitamin D is critical to bone health by regulating intestinal absorption of calcium, whereas proinflammatory cytokines, including IL-1, IL-6, IL-12, and TNF-α, are known to increase bone resorption. We hypothesized that vitamin D and these cytokines at the time of breast cancer diagnosis were predictive for fragility fractures in women receiving aromatase inhibitors (AIs). In a prospective cohort of 1,709 breast cancer patients treated with AIs, we measured the levels of 25-hydroxyvitamin D (25OHD), IL-1β, IL-6, IL-12, and TNF-α from baseline blood samples. The associations of these biomarkers were analyzed with bone turnover markers (BALP and TRACP), bone regulatory markers (OPG and RANKL), bone mineral density (BMD) close to cancer diagnosis, and risk of fragility fractures during a median of 7.5 years of follow up. Compared to patients with vitamin D deficiency, patients with sufficient levels had higher bone turnover, lower BMD, and higher fracture risk; the latter became non-significant after controlling for covariates including BMD and no longer existed when patients taking vitamin D supplement or bisphosphonates or with history of fracture or osteoporosis were excluded. There was a non-significant trend of higher levels of IL-1β and TNF-α associated with higher risk of fracture (highest vs. lowest tertile, IL-1β: adjusted HR=1.37, 95% CI=0.94-1.99; TNF-α: adjusted HR=1.38, 95% CI=0.96-1.98). Our results do not support proinflammatory cytokines or vitamin D levels as predictors for risk of fragility fractures in women receiving AIs for breast cancer.

Obesity and leptin in breast cancer angiogenesis.

At the time of breast cancer diagnosis, most patients meet the diagnostic criteria to be classified as obese or overweight. This can significantly impact patient outcome: breast cancer patients with obesity (body mass index > 30) have a poorer prognosis compared to patients with a lean BMI. Obesity is associated with hyperleptinemia, and leptin is a well-established driver of metastasis in breast cancer. However, the effect of hyperleptinemia on angiogenesis in breast cancer is less well-known. Angiogenesis is an important process in breast cancer because it is essential for tumor growth beyond 1mm3 in size as well as cancer cell circulation and metastasis. This review investigates the role of leptin in regulating angiogenesis, specifically within the context of breast cancer and the associated tumor microenvironment in obese patients.

7326 Breast and Ovarian Cancer are Increased in Women with Primary Ovarian Insufficiency and Early Menopause and Cancer is Increased in Family Members

Introduction: Next generation sequencing in women with primary ovarian insufficiency (POI) identified deleterious variants in DNA damage repair and transcription fidelity genes. Based on underlying genetics, we hypothesized that a subset of women with POI may also be predisposed to reproductive or hormonally influenced cancers and that family members may be at risk. Methods: Women with POI (≤40 years) and early menopause >40 and <45 years) were identified using ICD9 and 10 codes in electronic medical records (1995-2021) from two major healthcare systems in Utah and reviewed for accuracy. Women with POI and their relatives were linked to genealogy information using the Utah Population Database (UPDB) and to cancer diagnoses (breast, ovarian, endometrial, colon, testicular and prostate) using the Utah Cancer Registry. The relative risk (RR) of cancer in women with POI and in relatives was estimated by comparison to population rates matched by age, sex, and birthplace. We also identified POI pedigrees with an excess number of observed cancer cases compared to the expected number in population controls. Results: We identified 613 women with POI and 165 women with early menopause. Of these, 416 women with POI had at least three generations of genealogical data with 2,405 first-degree relatives, 6,798 second-degree relatives and 17,666 third-degree relatives. Breast cancer was significantly increased in women with POI (OR [95%CI] 1.89 [1.20, 2.84]; p=0.0056) and there was a borderline increase in ovarian cancer. Probands were 36.5±4.3 years when diagnosed with POI and 59.5±12.7 years (range 43-80 years) at the time of breast cancer diagnosis and only 2 women took hormone replacement therapy after age 50 years. When women with early menopause were added, breast cancer risk remained increased and ovarian cancer was also nominally significant (3.38 [1.15, 8.65]; p=0.032). There was no increased risk of endometrial cancer and there were no cases of colon cancer. Among second-degree relatives of women with POI and 3 generations of family members, there was a significantly increased risk of breast (1.28 [1.08, 1.71]; p=0.0078) and colon cancer (1.50 [1.14, 1.94]; p=0.0036). Prostate cancer was increased in first- (1.64 [1.18, 2.23]; p=0.0026), second- (1.54 [1.32, 1.79]; p<0.001), and third-degree relatives (1.33 [1.20, 1.48]; p<0.001). There were 27 POI pedigrees that were high risk for these reproductive or hormonally influenced cancer diagnoses. Conclusions: Our data suggest common risk factors for POI and reproductive or hormonally influenced cancers. Therefore, clinicians need tools to predict cancer risk and comorbid disease in women with POI and early menopause to adequately counsel about future health risk. This understanding may change recommendations for hormone replacement based on the underlying genetic cause of POI for an individual. Presentation: 6/3/2024

Reconstruction trends in New York City: A multi-decade, multi-institutional experience before and after the implementation of the Breast Cancer Provider Discussion Law

IntroductionThe potential benefits of breast reconstruction for achieving greater patient satisfaction, wellbeing, and functional outcomes after mastectomy have been widely acknowledged. However, sociodemographic and economic disparities exist in accessing reconstruction. This study aims to characterize the influence of various factors on access to reconstruction and investigate the impact of the Breast Cancer Provider Discussion Law (BCPDL), a legislation that mandates patient education and referral to plastic surgery at the time of breast cancer diagnosis, on utilization of reconstructive services. MethodsRetrospective chart review was performed to collect data on patients who underwent mastectomy at two institutions within the New York-Presbyterian system from 1998-2019. Sociodemographic, past medical history, and treatment approach information were recorded. Interrupted time series analysis and logistic regression were used for statistical analysis. Results6,122 patients were included in the cohort. 3,737 (61.04%) underwent reconstruction and 2,385 (38.96%) did not. We found that older age, Medicaid/Medicare insurance, higher tumor staging, and identity as Asian American/Pacific Islander were negative predictors of undergoing reconstruction. On interrupted time series analysis of the years prior to and the years following the 2010 BCPDL implementation, while there was an immediate increase in the proportion of patients who received reconstruction, the effects were not sustained. ConclusionOur data indicates that patient-physician communication alone may not be sufficient to bridge the gap in reconstructive care. This study highlights the need for consistent plastic surgery referral for sustained equal access to reconstructive services.

Mammographic features differ with body composition in women with breast cancer.

There are several breast cancer (BC) risk factors-many related to body composition, hormonal status, and fertility patterns. However, it is not known if risk factors in healthy women are associated with specific mammographic features at the time of BC diagnosis. Our aim was to assess the potential association between pre-diagnostic body composition and mammographic features in the diagnostic BC image. The prospective Malmö Diet and Cancer Study includes women with invasive BC from 1991 to 2014 (n = 1116). BC risk factors at baseline were registered (anthropometric measures, menopausal status, and parity) along with mammography data from BC diagnosis (breast density, mammographic tumor appearance, and mode of detection). We investigated associations between anthropometric measures and mammographic features via logistic regression analyses, yielding odds ratios (OR) with 95% confidence intervals (CI). There was an association between high body mass index (BMI) (≥ 30) at baseline and spiculated tumor appearance (OR 1.370 (95% CI: 0.941-2.010)), primarily in women with clinically detected cancers (OR 2.240 (95% CI: 1.280-3.940)), and in postmenopausal women (OR 1.580 (95% CI: 1.030-2.440)). Furthermore, an inverse association between high BMI (≥ 30) and high breast density (OR 0.270 (95% CI: 0.166-0.438)) was found. This study demonstrated an association between obesity and a spiculated mass on mammography-especially in women with clinically detected cancers and in postmenopausal women. These findings offer insights on the relationship between risk factors in healthy women and related mammographic features in subsequent BC. With increasing numbers of both BC incidence and women with obesity, it is important to highlight mammographic findings in women with an unhealthy weight. Women with obesity and BC may present with certain mammographic features. Spiculated masses were more common in women with obesity, especially postmenopausal women, and those with clinically detected BCs. Insights on the relationship between obesity and related mammographic features will aid mammographic interpretation.

A Retrospective Analysis of Diagnostic Breast Imaging Outcomes in Young Women at a Tertiary Care Center.

(1) Purpose: The purpose of this study was to describe the outcomes of diagnostic breast imaging and the incidence of delayed breast cancer diagnosis in the study population. (2) Methods: We collected the outcome data from diagnostic mammograms and/or breast ultrasounds (USs) performed on women between the ages of 30 and 50 with symptomatic breast clinical presentations between 2018 and 2019. (3) Results: Out of 171 eligible patients, 10 patients (5.8%) had BIRADS 0, 90 patients (52.6%) had benign findings (BIRADS 1 and 2), 41 (24.0%) patients had probable benign findings requiring short-term follow-up (BIRADS 3), while 30 (17.5%) patients had findings suspicious of malignancy (BIRADS 4 and 5). In the BIRADS 3 group, 92.7% had recommended follow-up, while in BIRADS 4 and 5, only 83.3% underwent recommended biopsy at a mean time of 1.7 weeks (range 0-22 wks) from their follow-up scan. Ten (6%) patients were diagnosed with breast cancer, all of whom had BIRADS 4 or 5, with a mean time of breast cancer diagnosis from initial diagnostic imaging of 2.2 weeks (range 1-22 wks). No patients had delayed breast cancer diagnosis in our cohort. (4) Conclusions: We conclude that diagnostic mammograms and breast US are appropriate investigations for clinical breast concerns in women aged 30-50 years.

Increased socioeconomic vulnerability in breast cancer diagnosis during the COVID-19 pandemic in Brazil

ObjectiveTo evaluate the impact of the coronavirus disease (COVID-19) pandemic on the time of breast cancer diagnosis in Brazil and associated socioeconomic factors. MethodsThis population-based retrospective study examined breast cancer diagnoses in women between 2019 and 2020 (n = 12,597). Two periods were evaluated: the pre-pandemic (March–December 2019) and pandemic periods (March–December 2020). Logistic regression was performed to calculate odds ratios and 95 % confidence intervals (CIs). ResultsThere was a 50.2 % reduction (p < 0.01) in the number of diagnoses, and the average time from the first consultation to diagnosis increased from 28 to 36 days during the first six months of the COVID-19 pandemic (p = 0.006). Before the pandemic, the regression model indicated an increased possibility of delay in breast cancer diagnosis in women with lower education levels (OR = 1.30; 95 % CI:1.14–1.48); who were residents in the north, northeast, or midwest regions (OR = 1.56; 95 % CI:1.35–1.81); and who presented staging I or II (OR = 1.96; 95 % CI:1.71–2.24). During the pandemic, there was an increase in the odds ratios for all variables: education, an increase of 10.8 %; region of residence, 20.5 %; and staging, 9.2 %. ConclusionThe COVID-19 pandemic exacerbated pre-existing socioeconomic disparities during the early detection of breast cancer. It is important that, at critical moments in health, interventions be carried out for patients in vulnerable circumstances, thus minimizing the effects of possible delays in diagnosis.

Correlation between PLR and NLR with Tumor Size in Breast Cancer Patients

Breast cancer is the most common malignancy in females globally and one of the main causes of cancer death. There are several markers of cancer-related inflammation to help predict the relationship between pathologic characteristics of breast cancer. The research objective was to analyze the correlation between PLR and NLR with associated tumor size in breast cancer. This was a retrospective study with a cross-sectional design. This study used secondary data from the medical records of breast cancer patients who met the inclusion criteria at Siti Khodijah Hospital, Sidoarjo from January 2021 to March 2023. The sample size was 54 subjects, patients with breast cancer confirmed by pathology anatomy. The exclusion criteria were patients with infection, autoimmune disease, and hematology disorder. All the subjects were female. The mean age at the time of breast cancer diagnosis was 50.18±10.23 years, range of 27-80 years old. Most of the patients were over 50 years as much as 28 (51.85 %), while there were 26 (48.14%) &gt; 50 years. The PLR range was 15.45-600.0, the NLR range was 0.58-9.98, tumor size range was 0.5-10.0 cm. Correlation between PLR and NLR with tumor size in breast cancer (p=0.351 and p=0.339). Correlation analysis showed that PLR and NLR had no significant correlation with tumor size ( r= -0.129, p=0.351 and r= -0.133, p=0.339). In conclusion, there is no significant correlation between PLR and NLR with histopathology of tumor size in patients with breast cancer.

Contribution of mammography to breast cancer detection among pathogenic germline BRCA carriers by age and mutated gene.

10615 Background: Healthy carriers of pathogenic germline BRCA 1/2 (gBRCA) may choose between risk reducing mastectomy and intensive screening surveillance. Current international guidelines recommend both annual breast MRI and annual mammography. The aim of this study was to investigate the added contribution of annual mammography in gBRCA carriers to the annual breast MRI. Methods: A retrospective study from 2 large centers comprising gBRCA carriers who were diagnosed with breast cancer between 2000-2022 and were aware of their gBRCA status prior breast cancer diagnosis. Collected data included age at diagnosis, mutated gene and mode of breast cancer diagnosis (MRI, mammography, ultrasound [US], or other means [including clinical or incidental findings]). Data on pregnancy and breastfeeding at the time of breast cancer diagnosis were also collected. Differences in the mode of diagnosis were analyzed by age (≤40y vs. &gt;40y) and mutated gene (BRCA1 vs. BRCA2). Results: The cohort included 200 gBRCA carries: 134 (67%) BRCA1, 62 (31%) BRCA2 and 4 (2%) with both BRCA1 and BRCA2 mutations. The median age at the time of breast cancer diagnosis was 41 (24-88). Most cancers (68%) were diagnosed by MRI, followed by mammography (14.5%), US (7%) and other means (10.5%). While MRI was the most common diagnosis modality in both age groups, the distribution of mode of diagnosis was significantly different in younger women (≤40y) where breast cancer detection was more commonly by US or following clinical findings, compared to older women, p&lt; 0.001 (see Table). Five women were pregnant and 9 women were breastfeeding at the time of breast cancer diagnosis, all age 40 or younger. Four (80%) of pregnant carriers and 5 (55.6%) of breastfeeding carriers were diagnosed by US. There was no difference in mode of diagnosis between BRCA1 to BRCA2 carriers, p=0.974. There were only 16 women under age 30 that were diagnosed with breast cancer, 2 (12.5%) of whom were diagnosed with mammography. Conclusions: MRI is the most common modality for breast cancer diagnosis in gBRCA carriers who were aware if there gBRCA prior breast cancer diagnosis. Annual mammography also has a meaningful role in this population. We did not identify a subgroup in which it could be omitted. The increased utility of US among younger women is attributed to reduced utilization of MRI/mammography during pregnancy and breastfeeding. This finding strengthens the role of US screening in gBRCA carriers who are not eligible for other methods of imaging. [Table: see text]

Diet quality and cardiometabolic risk factors among breast cancer survivors in the Pathways Study.

11039 Background: Women with breast cancer (BC) have higher risk of developing cardiometabolic conditions compared to women without BC. However, the relationship between healthy eating and onset of cardiometabolic conditions in BC survivors remains unknown. We set out to determine if diet quality at BC diagnosis was related to subsequent development of hypertension, diabetes, and dyslipidemia. Methods: This analysis included 3,415 participants from the Pathways Study, a prospective cohort of women diagnosed with invasive BC (stages I-IV) at Kaiser Permanente Northern California (KPNC) between 2005 and 2013. Food frequency questionnaires were administered at or around the time of BC diagnosis and five diet quality indices (DQI) aligned with healthy eating were evaluated: Dietary Approaches to Stop Hypertension (DASH), a healthy plant-based dietary index (hPDI), 2020 Healthy Eating Index (HEI), American Cancer Society nutrition guidelines (ACS), and the alternate Mediterranean Diet (aMED). Incident hypertension, diabetes, and dyslipidemia were ascertained through electronic health records and participants were followed through first indication of these conditions, disenrollment from KPNC, death, or December 31, 2021. Scores were categorized into ascending quartiles of concordance for each DQI, and multivariable adjusted hazard ratios (HR) and 95% confidence intervals (CI) were estimated. Results: There were 554 (16.2%) incident cases of hypertension, 362 (10.6%) of diabetes, and 652 (19.1%) of dyslipidemia over 39,263 person-years of follow-up. Participants in the highest compared to lowest HEI quartile had lower risks of hypertension (HR=0.70, 95% CI 0.53-0.92, Ptrend&lt;0.01), diabetes (HR=0.56, 95% CI 0.40-0.77, Ptrend&lt;0.001), and dyslipidemia (HR=0.76, 95% CI 0.59-0.99, Ptrend=0.03). Participants in the highest vs lowest hPDI quartile had lower risks of hypertension (HR=0.74, 95% CI 0.55-0.98, Ptrend&lt;0.05) and diabetes (HR=0.65, 95% CI 0.46-0.93, Ptrend=0.02), but not dyslipidemia. Women in the highest vs lowest DASH and ACS quartiles had lower risks of diabetes (DASH:HR=0.56, 95% CI 0.39-0.79, Ptrend&lt;0.001; ACS:HR=0.57, 95% CI 0.40-0.79, Ptrend&lt;0.001), but not hypertension or dyslipidemia. No statistically significant differences for aMED were observed between those in the highest vs lowest quartiles. Overall, HRs were similar across DQIs for hypertension and diabetes, except for aMED, which slightly attenuated for diabetes. Conclusions: Diets concordant with HEI may provide the most overall benefit for preventing cardiometabolic conditions after a BC diagnosis. The benefit of diets aligned with hPDI, DASH, ACS, and aMED appear to vary by cardiometabolic condition. Future analyses will examine how these benefits may be modified by BC treatments. Consuming a healthful diet should be recommended to BC survivors for long-term cardiovascular health.

Clinical differences and management trends of localized breast cancer in the advanced geriatric population.

e12543 Background: Breast cancer remains the most common cancer diagnosis in women and, with the aging Baby Boomer population, is poised to represent an even larger volume of oncologic care in the United States over the coming decades. Combined with limited evidence-based guidelines for geriatric patients, particularly those above the age of 80, there exists the potential for unnecessary morbidity and mortality. This study aims to shed light on the characteristics of this population, including disparities, with an aim to identify subsets of patients who may benefit from more aggressive treatment. Methods: This was a retrospective cohort study to examine key clinical differences between the advanced geriatric breast cancer population (≥80 years) and those of younger age, comparing comorbidities, tumor characteristics, and management trends. The Charleston Area Medical Center cancer registry was queried from 2009-2022 for females diagnosed with invasive breast cancer who had surgery for localized disease, excluding those with previous malignancies. Data were analyzed with SAS 9.4 using student’s t-test for continuous variables, Chi-square or Fisher’s exact for categorical variables, and 5-year survival rates attained via Cox regression models. Results: The analysis involved 1041 female patients, divided into two age groups: 969 who were &lt; 80 years old and 72 who were ≥80 years old at time of breast cancer diagnosis. The ≥80 group had significantly more individuals with hypertension, 83.3% v 63.7% (p &lt; .001), osteoporosis, 26.8% v 9.5% (p &lt; .001), cardiac arrhythmia, 18.1% v 7.3% (p = .001), and CVA, 11.1% v 4.5% (p = .014), than the &lt; 80 group. Looking at overall trend, tumor grade was significantly (p = .040) lower in the ≥80 group than the &lt; 80 group, G1 34.7% v 24.9%, G2 44.4% v 45.4%, G3 20.8% v 29.7%, respectively. Her2neu positivity was significantly (p = .010) lower in the ≥80 group at 0.0% compared to the &lt; 80 group at 8.4%. There was no difference in the rate of endocrine therapy between the two groups (p = 0.320). Only 26.4% of the ≥80 group received radiotherapy compared to 79.0% of the &lt; 80 group (p &lt; .001). None of the ≥80 group received chemotherapy compared to 22.5% of the &lt; 80 group (p &lt; .001). Overall, 5-year survival for those &lt; 80 and ≥80 was 92% and 84%, respectively (p &lt; .001). Conclusions: In summary, patients 80 years of age or older were more likely to have hypertension, osteoporosis, cardiac arrhythmia, and history of CVA. Regarding tumor characteristics, both grade and Her2neu positivity were significantly higher in the &lt; 80 group. There was no difference in the administration of endocrine therapy. Radiotherapy and chemotherapy, however, were used at significantly lower rates in the advanced geriatric population, likely in adherence with current NCCN guidelines for adjuvant therapy in patients ≥70. Further investigation may help to elucidate subgroups amenable to more aggressive adjuvant therapies.

Abstract PO1-11-05: Diet quality and cardiovascular disease risk among breast cancer survivors in the Pathways Study

Abstract Background: While studies have shown that breast cancer survivors with healthier diets have a lower risk of non-breast cancer-specific and all-cause mortality after a breast cancer diagnosis, the relationship between diet quality and cardiovascular disease (CVD) among breast cancer survivors is not well characterized. We examined the association between diet quality at the time of breast cancer diagnosis and CVD-related outcomes in the Pathways Study, a prospective cohort of 3,415 women diagnosed with invasive breast cancer. Methods: This analysis included four diet quality indices (DQIs) consistent with healthy eating: 1. Dietary Approaches to Stop Hypertension (DASH), 2. healthy plant-based dietary index (hPDI), 3. 2015 Healthy Eating Index (HEI), 4. American Cancer Society nutrition guidelines (ACS). Each DQI was calculated from food frequency questionnaires (FFQ) at or around the time of breast cancer diagnosis, between 2005 and 2013, with a higher score representing a more healthful dietary pattern. DQI scores were categorized into quartiles with the most concordant diets in the highest quartile and the least concordant diets in the lowest quartile, for each DQI. CVD outcomes were ascertained through December 31, 2021 and included ischemic heart disease, heart failure, cardiomyopathy, stroke/transient ischemic attack, arrhythmia, cardiac arrest, valvular disease, venous thromboembolic disease and CVD-related death. Hazard ratios (HR) and 95% confidence intervals (CI) were estimated from proportional hazards regression accounting for clinical and demographic factors. Results: FFQs were completed an average 2.2 (range=0.3-7.6) months after a breast cancer diagnosis, and a total 623 (18.2%) incident CVD events and 340 (10.0%) CVD-related deaths were ascertained over 39,263 person-years of follow-up. Participants in the highest quartile of the DASH DQI had substantially reduced risks of heart failure (HR=0.50, 95% CI 0.31-0.81), arrhythmia (HR=0.76, 95% CI 0.62-0.93), cardiac arrest (HR=0.75, 95% CI 0.60-0.93), valvular disease (HR=0.77, 95% CI 0.62-0.96), venous thromboembolic disease (HR=0.74, 95% CI 0.59-0.92), and a 33% reduced risk of CVD-related death (HR=0.67, 95% CI 0.48-0.95) relative to those in the lowest quartile. Tests for trend across quartiles of the DASH DQI were also statistically significant at a p-value &amp;lt; 0.03. The only notable association found in the other three DQIs was between hPDI and lower risk of heart failure (HR=0.61, 95% CI 0.39-0.95) in women in the highest quartile compared to the lowest quartile (Table 1). Summary: These findings suggest that diets concordant with DASH and hPDI dietary patterns, may be beneficial for preventing CVD and CVD-related death after a breast cancer diagnosis. Table 1.

Abstract PO3-27-07: Age at diagnosis and the food environment are associated with postdiagnosis weight gain among Black American breast cancer survivors in Maryland

Abstract Background: Weight management is now included in the American Cancer Society/American Society of Clinical Oncology Breast Cancer Survivorship Care Guidelines due to its clinical impact on breast cancer (BC) survivorship outcomes. While numerous individual-level risk factors for weight gain after BC diagnosis have been identified, such as younger age at diagnosis, cancer stage, and cancer treatments (chemotherapy), there are limited data on the impact of neighborhood-level factors associated with weight change postdiagnosis among Black BC survivors. Methods: Utilizing social media recruitment strategies and survivor networks, we recruited 100 Black female BC survivors to complete an online survey, including demographic, clinical characteristics, and lifestyle factors, between January 5, 2022, and August 18, 2022. To capture the food environment, we utilized the 2023 Food Environment Index County Health Rankings, which accounts for access to healthy foods due to proximity and income (considering the distance an individual lives from a grocery store or supermarket, locations for health food purchases in most communities, and the inability to access healthy food because of cost barriers). The index ranges from 0 (worst) to 10 (best). Our outcome of postdiagnosis weight gain was calculated as percent weight change from time at diagnosis to time of survey, calculated as ([weight at survey – weight at diagnosis]/weight at diagnosis) × 100. Participants were grouped into mutually exclusive categories of stable weight (within ± 3%) or weight loss (≤-3%) compared to weight gain (≥ 3%). Adjusted odds ratios (aORs) and 95% confidence intervals (CI) were calculated for the associations between clinical factors, county-level food environment index, and postdiagnosis weight gain. Results: The average ages at time of survey and at primary BC diagnosis were 58.6 years (standard deviation [SD]= 10.1) and 49.1 years (SD=10.2), respectively. Most women (70%) were diagnosed with invasive BC and only 22% were currently undergoing treatment at the time of the survey. While only 7% reported being obese at the time of BC diagnosis, 54% reported being obese at the time of survey which was on average 9 years post-BC diagnosis; and while 61 women had weight loss or stable weight, 34 women experienced weight gain postdiagnosis. Among the 95 women included in multivariable models who reported weight and height measurements for calculating weight change, women ≥50 years of age at BC diagnosis (versus &amp;lt; 50 years) were 3.43 times more likely to gain weight after diagnosis (95% CI 1.13-11.50). Women living in counties with a Food Environment Index ≥8.8 (median cut-point compared to &amp;lt; 8.8) were significantly less likely to experience weight gain (aOR 0.11; 95% CI 0.01-0.90). Stage and BC treatments were not significantly associated with weight gain. Conclusions: Our study findings demonstrate the importance of evaluating the food environment during BC survivorship and longitudinal monitoring of weight postdiagnosis to mitigate weight gain among Black BC survivors. Our findings will be used to inform a larger prospective study and future interventions among this population. Citation Format: Avonne Connor, Katherine Ho, Kate Dibble, Kala Visvanathan.

Abstract PO5-10-07: Risk factors associated with secondary cancers in AYA patients with breast cancer. A SEER database study

Abstract Background Adolescents and young adults (AYA) diagnosed with breast cancer face unique challenges and have distinct characteristics compared to older patients. While primary breast cancer remains a significant concern, the risk of developing secondary cancers in this population is also of great importance. This study aimed to identify these risk factors by analyzing a large cohort of AYA breast cancer patients using SEER (Surveillance Epidemiology and End Result) Database. Methods Patients were identified from SEER Research Data 17, from 2000 to 2019. Patients aged 18-39 years with breast cancer and at least 1 year of survival were identified. Secondary cancers were then identified and included any disease site. Patient demographic and clinical characteristics were summarized by secondary cancer status using Mann-Whitney U and Fisher’s exact tests. Overall survival from the initial breast cancer diagnosis was summarized by secondary cancer status using standard Kaplan-Meier methods, where the median and 3/5-year rates were estimated with 95% confidence intervals. Comparisons were made using the log-rank test. SAS v9.4 (Cary, NC) was used at a significance level of 0.05. Results A total of 47,912 AYA breast cancer patients were identified, of which 2,886 (6.0%) developed a secondary cancer at least 1 year after the initial breast cancer diagnosis. When comparing patients with and without secondary cancers, we observed significant differences with respect to age at initial breast cancer diagnosis, race, stage, nodal status, surgical procedure, ER status, PR status, Her2 status, and sub-type (Table 1). The analysis of overall survival showed that, from the time of breast cancer diagnosis, there was no statistically significant difference between patients with and without secondary cancers. However, this may be due to an immortal time bias. Breast was the most common site of secondary cancer (67%) followed by gynecological (7%), colorectal (3.7%), skin (3.4%) lung and hematologic (2.7%) Compared to other subtypes, TNBC patients were found to have much shorter time to secondary cancer development of 38 months compared to Her2+ and ER/PR+ (40 and 45 months respectively, P&amp;lt; 0.001). Black and Hispanic individuals were found to have higher rates (7.4% and 6.3%) and earlier development of secondary cancer (76 months and 74 months) as compared to whites and Asians (5.9% and 5%, 88 months and 81 months, P&amp;lt; 0.001 and P&amp;lt; 0.002 respectively). Conclusion This study identified several risk factors associated with the development of secondary cancers in AYA breast cancer patients such as age at initial breast cancer diagnosis, race, stage, nodal status, surgical procedure and sub-type. Higher rates and early development of secondary cancer were observed among TNBC subtype and Black and Hispanic races that calls for further investigation and tailored interventions to improve outcomes in specific patient populations.

Abstract PO2-11-08: Divorce and marital dissolution after Breast Cancer diagnosis in young breast cancer survivors in Mexico

Abstract Background: The current literature suggests that facing breast cancer can have significant effects on the relationship, for the better or for the worse. The needs of younger women with breast cancer are receiving increased attention, as 23.1% of all newly diagnosed invasive cancer occur in women age 50 or younger. Marital relationships, in particular, may be strained for younger cancer patients as they face health, emotional, and financial stressors from their cancer. The few studies that are available to date have examined the effect of breast cancer diagnosis on marital and relationship Purpose: We examined marital outcomes among young locally advanced breast cancer patients in our institution Methods: Eligible participants were women with diagnosis of breast cancer stage I–III, were at least 6 months post diagnosis, and age 50 or younger at the time of diagnosis. Demographic data collected. Participants reported their marital o relationship status at time of breast cancer diagnosis and after at least 6 moth post diagnosis, whether they were currently married or a member of an unmarried couple, divorced, widowed or separated Other variables examined regarding a possible separation, the reasons for separation, the influence of the cancer on the relationship, the positive or negative perception of the impact of cancer on the relationship, the highest educational attainment and employment status. Descriptive statistics, percentages, frequencies, mean values and standard deviations were calculated. Results: In total, 75 patients were eligible for inclusion with a total of 250 patient with diagnosis of locally advanced breast cancer. The median age was 44 (range 30–48). Most of the patients, stage I or II tumors (55%). The divorce or separation rate was 36%, higher than reported in the literature (14.5%). Among those who were separated, 77% reported that cancer contributed to the separation or divorce. Also, for those who stayed together, 81% reported an impact of the cancer on the relationship, of which 50% reported a negative impact. Of those who had separated, none were in a new relationship. Conclusions: The emotional burdens of cancer may lead to marital stress for younger cancer survivors.; support systems are needed to assist them in the years following diagnosis. Because the marital relationship has multiple dimensions, it is also important to explore and identify those areas of the couple's life that are affected by the experience Citation Format: Saúl Campos-Gomez, Andrea Ovando Trujillo.

Abstract PS10-02: Association between Germline Mutation Status and Overall Survival among Women with Breast Cancer in Population-based Studies in the United States

Abstract Background: The influence of germline pathogenic variants (PVs) in breast cancer predisposition genes on overall survival (OS) after breast cancer diagnosis is not well defined, particularly for PVs in genes other than BRCA1 and BRCA2, and in the context of estrogen-receptor (ER) positive breast cancer. Even for BRCA1/2, OS estimates in women with breast cancer have primarily been derived from high-risk women qualifying for genetic testing due to young age at diagnosis or family history of cancer, and OS estimates by germline PV status from population-based studies are lacking. Methods: The study included 16,797 prospectively followed women with locoregional breast cancer within the population-based CARRIERS study who underwent surgical resection of the primary tumor. OS was compared between germline PV carriers and non-carriers (negative for germline PVs in 12 breast cancer predisposition genes) from the time of breast cancer diagnosis in a multivariable Cox proportional hazard regression analysis adjusting for age and menopausal status at diagnosis, race/ethnicity, ER status, type of surgery, use of adjuvant radiation, chemotherapy and endocrine agents, and prophylactic oophorectomy. Further subset analyses by race/ethnicity ER status of the primary tumor and adjusting for relevant covariates were also performed. Results: Germline PVs in ATM, BRCA1, BRCA2, CHEK2, or PALB2 were detected in 5.6% of the women in the study [ATM: 142 (0.8%), BRCA1: 206 (1.2%), BRCA2: 260 (1.5%), CHEK2:167 (1.0%) and PALB2:116 (0.7%)]. Compared to non-carriers, a significant difference in OS was not observed for germline PV carriers in ATM, BRCA1, BRCA2, or CHEK2 in the overall study population. However, a trend towards worse OS was noted for PALB2 PV carriers compared to non-carriers although this was not statistically significant (Hazard Ratio (HR): 1.36, 95%CI: 0.98 – 1.89, p=0.06). Further subset analysis by race/ethnicity demonstrated that the OS was significantly worse among Black PALB2 PV carriers (HR: 3.11, 95%CI: 1.74 – 5.55, p&amp;lt; 0.001) but not in non-Hispanic White PALB2 PV carriers (HR: 1.00, 95%CI: 0.59 – 1.70, p=0.98) compared to non-carriers within the same race/ethnicity. Among 12,780 women with ER+ breast cancer, compared to non-carriers, OS was significantly worse in BRCA2 PV carriers (HR: 1.51, 95%CI: 1.06 – 2.16, p=0.02) and a trend towards worse OS was observed in BRCA1 PV carriers (HR:1.53, 95%CI:0.93 – 2.51, p=0.09). Among women with ER-negative breast cancer, a significant difference in OS was not observed between PV carriers in each of the five genes and non-carriers. Conclusions: The differences in OS by race/ethnicity in PALB2 PV carriers and by ER status of the tumor in BRCA2 PV carriers warrant further investigation of underlying tumor biology and assessment of endocrine sensitivity of breast cancer in germline PV carriers.

Abstract PO2-12-11: Ocular Toxicity of Tamoxifen in Patients with Breast Cancer

Abstract Background: The latest recommendations in breast cancer treatment protocols with tamoxifen indicate that it should be used from five to 10 years. It depends mainly on the cumulative dose of the drug in the body. Despite its multiplicity, the various studies conducted on this subject did not reach conclusive results. Objectives: This research aims to study retinopathy associated with hormonal treatment of breast cancer using tamoxifen. Methods: A cross-sectional study was conducted at Al-Mouwasat University Hospital on a sample of 130 eyes according to (G-Power) with a statistical power of 95%. The participants were briefed on the research and consented on the ethical considerations. Then, the patients who entered the study were interrogated, clinically examined, and were asked about their medical history, the time of breast cancer diagnosis along with the details about the treatment protocols they underwent or currently undergoing. The refractive errors were measured with an automatic refractive device, then they were examined on the slit lamp to investigate the refractory media, then the corrected and uncorrected visual acuity were taken. Finally, after ensuring that the inclusion criteria were met and excluding those who fulfil one or more of the exclusion criteria, optical coherence tomography was performed using SD-OCT technique to measure and review the retinal thickness map in circles of 1-3-6 mm, respectively, to notice possible changes on it. Results: We found that the use of tamoxifen irrespective to cumulative dose leads to increase in the macula thickness values in the upper and lower sectors within the 3 mm circle, and to significant decrease in the macula thickness values in the upper and lower sectors within the 6 mm circle, in addition to decrease in nasal sector thickness within the circles of 3 and 6 mm. Conclusion: We conclude that the difference between people treated with tamoxifen and those not treated with it is not limited to the occurrence of crystals deposition in the macular area or the presence of a cavity in the central macula (with or without typical cystic macular edema), but rather to existence of macula thickness differences unrelated to the cumulative dose of the drug, whether by increase or decrease in thickness of the upper, lower and nasal segments.

Diet quality and cardiovascular disease risk among breast cancer survivors in the Pathways Study.

Women with breast cancer are at higher risk of cardiovascular disease (CVD) compared with women without breast cancer. Whether higher diet quality at breast cancer diagnosis lowers this risk remains unknown. We set out to determine if higher diet quality at breast cancer diagnosis was related to lower risk of CVD and CVD-related death. This analysis included 3415 participants from the Pathway Study, a prospective cohort of women diagnosed with invasive breast cancer at Kaiser Permanente Northern California between 2005 and 2013 and followed through December 31, 2021. Scores from 5 diet quality indices consistent with healthy eating were obtained at the time of breast cancer diagnosis. Scores were categorized into ascending quartiles of concordance for each diet quality index, and multivariable adjusted hazard ratios (HRs) and 95% confidence intervals (CIs) were estimated. P values were 2-sided. The Dietary Approaches to Stop Hypertension diet quality index was associated with lower risk of heart failure (HR = 0.53, 95% CI = 0.33 to 0.87; Ptrend = .03), arrhythmia (HR = 0.77, 95% CI = 0.62 to 0.94; Ptrend = .008), cardiac arrest (HR = 0.77, 95% CI = 0.61 to 0.96; Ptrend = .02), valvular heart disease (HR = 0.79, 95% CI = 0.64 to 0.98; Ptrend = .046), venous thromboembolic disease (HR = 0.75, 95% CI = 0.60 to 0.93; Ptrend = .01), and CVD-related death (HR = 0.70, 95% CI = 0.50 to 0.99; Ptrend = .04), when comparing the highest with lowest quartiles. Inverse associations were also found between the healthy plant-based dietary index and heart failure (HR = 0.60, 95% CI = 0.39 to 0.94; Ptrend = .02), as well as the alternate Mediterranean dietary index and arrhythmia (HR = 0.74, 95% CI = 0.60 to 0.93; Ptrend = .02). Among newly diagnosed breast cancer patients, higher diet quality at diagnosis was associated with lower risk of CVD events and death.

Association of Positive Family History and Clinicopathological Features in Breast Cancer in Young Indian Females – A Pilot Study

ABSTRACT Introduction: Breast cancer is the most common cancer in Indian females, accounting for 31.8% of all cancers. Young women with breast cancer are those under 40 years of age. These patients have higher chances of positive family history and genetic susceptibility. Approximately 5%–10% of cases of breast cancer are associated with a family history. In this study, we planned to identify a relationship between family history and the clinical, pathological, and genetic characteristics of breast cancer in young women. Methods: Retrospectively, data from patients aged &lt; 40 years with breast cancer, were collected from 2019 to 2022. Detailed information about the family history of the patients including the degree and number of relatives affected and the types of cancer was recorded. The tumors were characterized based on the pathological grade, estrogen receptor, progesterone receptor, human epidermal growth factor receptor 2 status, and BRCA variant genetic analysis. Results: Of 125 females with young breast cancer, 24 patients (19%) had a first- or second-degree relative with a history of cancer at the time of breast cancer diagnosis. Four (16%) of these positive cases had BRCA mutation detected. Bilateral breast cancer was detected in 12% of women with positive family history. Conclusion: Clinicians are urged to use detailed family histories for young women with breast cancer for early screening and education of the first- and second-degree relatives of these patients to detect the hidden cases.

Prevalence and impact of fertility concerns in young women with breast cancer

Survey data from the Mayo Clinic Breast Disease Registry were used to assess fertility counseling and fertility preservation strategies in a modern cohort of young women with breast cancer. One hundred respondents were identified who were under age 50 at the time of breast cancer diagnosis and who expressed interest in future childbearing near the time of diagnosis and/or 1 year later. Ninety-three percent of the 81 respondents to the year one survey recalled fertility counseling prior to cancer treatment. Most who reported a high level of fertility concern declared that this concern had impacted their treatment decisions, often shortening their planned duration of endocrine therapy. Approximately half had taken steps to preserve future fertility, and a third had used a gonadotropin-releasing hormone agonist either alone or combined with another method (e.g., embryo or oocyte cryopreservation).
