RESUMEN
INTRODUCTION: Premenopausal women with high-risk hormone receptor (HR)-positive breast cancer often receive ovarian function suppression (OFS) and anti-estrogen therapy which induces near complete estrogen deprivation (NCED). This treatment improves recurrence-free survival but may increase cardiovascular risk. We sought to identify patterns of cardiovascular care and outcomes in premenopausal women with operable breast cancer. METHODS: Premenopausal women ≤ 50 years of age with stage I-III HR-positive or triple negative breast cancer (TNBC) were identified by retrospective review. We categorized women into 3 groups based on anti-estrogen therapy approach: NCED (HR + OFS), anti-estrogen therapy without OFS (HRnoOFS), and no anti-estrogen therapy (TNBC). Baseline characteristics, post-diagnosis cardiovascular events and cardiovascular actions (tests, referrals and medications) were recorded. Categorical variables were compared among the groups using chi-square and Fisher's exact tests; continuous outcomes were compared using ANOVA. RESULTS: 82, 83, and 52 women were identified in the HR + OFS, HRnoOFS, and TNBC groups respectively; mean follow-up was 5.0 years. Mean number of cardiovascular actions per year were highest in the HR + OFS group compared with HRnoOFS and TNBC groups (0.35 vs. 0.20 and 0.27, respectively; P = .036). The HR + OFS group had significantly more referrals and tests per year than the other groups. Cardiovascular medication initiation did not differ among groups. CONCLUSIONS: In this early follow-up period, there were meaningful numbers of cardiovascular actions, with women on NCED experiencing the most per year. Future work should seek to further understand the impact of anti-estrogen therapy on the cardiovascular health of premenopausal women and test strategies to mitigate cardiotoxicity.

Survival with operable breast cancer has improved markedly in recent decades, however, treatment-related cardiovascular toxicities threaten to offset these gains. Ovarian function suppression paired with aromatase inhibition, for premenopausal women with hormone receptor (HR)-positive breast cancer, is a newer widely adopted therapy with the potential for significant long-term cardiovascular toxicity. Abrupt estrogen deprivation for non-cancer reasons is associated with accelerated coronary artery disease. Women with breast cancer treated with aromatase inhibition in addition to ovarian function suppression experience a dual hit with regards to estrogen exposure. The CaRdiac Outcomes With Near-complete estrogen deprivation (CROWN) study seeks to understand the early, subclinical natural history of cardiovascular compromise in young women undergoing near-complete estrogen deprivation (NCED) therapy. It is critical to understand the early subclinical development of cardiovascular disease to identify a window for therapeutic intervention before overt cardiovascular events occur. This three-site regional study (Atrium Health Wake Forest, Duke, and Virginia Commonwealth University) uses serial stress cardiac magnetic resonance (CMR) imaging and cardiac computed tomography angiography (CCTA) obtained during the initial two years of NCED therapy to study myocardial prefusion reserve (MPR), large cardiovascular vessel changes, left ventricular function, and other cardiovascular parameters. The CROWN cohort will consist of 90 premenopausal women with breast cancer, 67 with HR-positive disease receiving NCED and 23 comparators with HR-negative disease. Participants will undergo three annual CMR scans and 2 CCTA scans during the 2-year study period. After initial activation hurdles, accrual has been brisk, and the study is expected to complete accrual in December 2024. Efforts are in place to encourage participant retention with the study primary outcome, change in MPR between the two groups, to be reported in 2026 to 2027. The results of this study will enable premenopausal women with breast cancer to balance the health burdens of cancer at a young age and treatment-related cardiovascular morbidity. Finally, the tools developed here can be utilized to study cardiovascular risk across a range of cancer types and cancer therapies with the ultimate goals of both developing generalizable risk stratification tools as well as validating interventions which prevent overt cardiovascular compromise.

Purpose: Cardiotoxicity of antineoplastic therapies is increasingly a risk to cancer patients treated with curative intent with years of life to protect. Studies highlight the importance of identifying early cardiac decline in cancer patients undergoing cardiotoxic therapies. Accurate tools to study this are a critical clinical need. Current and emerging methods for assessing cardiotoxicity are too coarse for identifying preclinical cardiac degradation or too cumbersome for clinical implementation. Approach: In the previous work, we developed a noninvasive biomechanical model-based elasticity imaging methodology (BEIM) to assess mechanical stiffness changes of the left ventricle (LV) based on routine cine cardiac magnetic resonance (CMR) images. We examine this methodology to assess methodological reproducibility. We assessed a cohort of 10 participants that underwent test/retest short-axis CMR imaging at baseline and follow-up sessions as part of a previous publicly available study. We compare test images to retest images acquired within the same session to assess within-session reproducibility. We also compare test and retest images acquired at the baseline imaging session to test and retest images acquired at the follow-up imaging session to assess between-session reproducibility. Results: We establish the within-session and between-session reproducibility of our method, with global elasticity demonstrating repeatability within a range previously demonstrated in cardiac strain imaging studies. We demonstrate increased repeatability of global elasticity compared to segmental elasticity for both within-session and between-session. Within-subject coefficients of variation for within-session test/retest images globally for all modulus directions and a mechanical fractional mechanical stiffness anisotropy metric ranged from 11% to 28%. Conclusions: Results suggest that our methodology can reproducibly generate estimates of relative mechanical elasticity of the LV and provides a threshold for distinguishing true changes in myocardial mechanical stiffness from experimental variation. BEIM has applications in identifying preclinical cardiotoxicity in breast cancer patients undergoing antineoplastic therapies.
RESUMEN
Current tools to assess breast cancer response to neoadjuvant chemotherapy cannot reliably predict disease eradication, which if possible, could allow early cessation of therapy. In this work, we assessed the ability of an image data-driven mathematical modeling approach for dynamic characterization of breast cancer response to neoadjuvant therapy. We retrospectively analyzed patients enrolled in the I-SPY 2 TRIAL at the Atrium Health Wake Forest Baptist Comprehensive Cancer Center. Patients enrolled on the study received four MR imaging examinations during neoadjuvant therapy with acquisitions at baseline (T0), 3-weeks/early-treatment (T1), 12-weeks/mid-treatment (T2), and completion of therapy prior to surgery (T3). We use a biophysical mathematical model of tumor growth to generate spatial estimates of tumor proliferation to characterize the dynamics of treatment response. Using histogram summary metrics to quantify estimated tumor proliferation maps, we found strong correlation of mathematical model-estimated tumor proliferation with residual cancer burden, with Pearson correlation coefficients ranging from 0.88 and 0.97 between T0 and T2, representing a significant improvement from conventional assessment methods of change in mean apparent diffusion coefficient and functional tumor volume. This data shows the significant promise of imaging-based biophysical mathematical modeling methods for dynamic characterization of patient-specific response to neoadjuvant therapy with correlation to residual disease outcomes.

CONTEXT: It is important to address fatigue and co-occurring symptoms during chemotherapy to preserve quality of life in patients with gastrointestinal (GI) cancer. OBJECTIVE: To conduct a randomized controlled pilot study of a Yoga Skills Training (YST) intervention compared to an attention control (AC) among adults diagnosed with GI cancer. METHODS: YST consisted of four 30-minute sessions delivered individually during chemotherapy plus home practice. AC provided empathic attention plus home diaries. Patient-reported (PROMIS T-score) assessments of fatigue, depressive symptoms, sleep disturbances, and psychological stress (Perceived Stress Scale) were collected at chemotherapy visits: baseline, Week 8, Week 10 and Week 14, and analyzed using a mixed effects model. Inflammatory cytokines were assessed at baseline and Week 10. RESULTS: Forty-four of 77 adults approached agreed to participate (57%; YST n = 23; AC n = 21). Participants' mean age was 58 years and 48% were men. Participants randomized to YST reported a larger decline in fatigue (-2.4 difference, d = 0.30) and depressive symptoms (-2.5 difference, d = 0.30) than AC participants from baseline to Week 10 and sleep disturbances at Week 8 (-3.9 difference, d = 0.50). Differences in magnitude of change in symptoms were consistent with or exceeded a minimally important difference. Psychological stress decreased more in the AC at Week 10 (d = 0.30). Reductions in inflammatory cytokines (IL-6, sTNF R1) were larger in the YST group than AC. CONCLUSION: YST showed promise for improving fatigue, depressive symptoms, sleep disturbances, and inflammation. YST is also feasible and reaches patients underrepresented in yoga research (i.e., GI cancer, men), thus warranting further examination.

Background: Premenopausal women with high-risk hormone receptor (HR)-positive breast cancer often receive ovarian function suppression (OFS) with aromatase inhibitor therapy; however, abrupt menopause induction, together with further decrements in estrogen exposure through aromatase inhibition, may affect cardiovascular microcirculatory function. We examined adenosine-induced changes in left ventricular (LV) myocardial T1, a potential subclinical marker of LV microcirculatory function in premenopausal women undergoing treatment for breast cancer. Methods: Twenty-one premenopausal women (14 with HR-positive breast cancer receiving OFS with an aromatase inhibitor and 7 comparator women with triple-negative breast cancer [TNBC] who had completed primary systemic therapy) underwent serial resting and adenosine cardiovascular magnetic resonance imaging measurements of LV myocardial T1 and LV volumes, mass, and ejection fraction. All statistical tests were 2-sided. Results: After a median of 4.0 months (range = 3.1-5.7 months), the stress to resting ratio of LV myocardial T1 declined in women with HR-positive breast cancer (-1.3%, 95% confidence interval [CI] = -3.4% to 0.7%) relative to those with TNBC (3.2%, 95% CI = -1.2% to 7.6%, P = .02). After accounting for age, LV stroke volume, LV ejection fraction, diastolic blood pressure, and breast cancer subtype women with HR-positive breast cancer experienced a blunted T1 response after adenosine relative to women with TNBC (difference = -4.7%, 95% CI = -7.3% to -2.1%, P difference = .002). Conclusions: Over the brief interval examined, women with HR-positive breast cancer receiving OFS with an aromatase inhibitor experienced reductions in adenosine-associated changes in LV myocardial T1 relative to women who received nonhormonal therapy for TNBC. These findings suggest a possible adverse impact on LV myocardial microcirculatory function in premenopausal women with breast cancer receiving hormone deprivation therapy.

BACKGROUND: Our study aim was to evaluate neuromuscular ultrasound (NMUS) for the assessment of taxane chemotherapy-induced peripheral neuropathy (CIPN), the dose-limiting toxicity of this agent. METHODS: This cross-sectional study of breast cancer patients with taxane CIPN measured nerve cross-sectional area (CSA) by NMUS and compared with healthy historical controls. Correlations were determined between CSA and symptom scale, nerve conduction studies, and intraepidermal nerve fiber density (IENFD). RESULTS: A total of 20 participants reported moderate CIPN symptoms at a median of 3.8 months following the last taxane dose. Sural nerve CSA was 1.2 mm2 smaller than healthy controls (P ≤ .01). Older age and time since taxane were associated with smaller sural nerve CSA. For each 1 mm2 decrease in sural nerve CSA, distal IENFD decreased by 2.1 nerve/mm (R2 0.30; P = .04). CONCLUSIONS: These data support a sensory predominant taxane neuropathy or neuronopathy and warrant future research on longitudinal NMUS assessment of CIPN.

BACKGROUND: BRCA germline pathogenic variants represent the most common inherited mechanism predisposing individuals to breast cancer, while germline pathogenic variants in one of the mismatch repair (MMR) genes represent the most common colon cancer-predisposing inherited syndrome, known as the Lynch syndrome (LS). Individuals who harbor pathogenic germline variants for both syndromes are extremely rare. Germline testing is now done routinely for patients with breast cancer and MMR testing is recommended for nearly all patients diagnosed with colon or rectal cancer (Benson et al in NCCN clinical practice guidelines in oncology (NCCN guidelines) colon cancer (Version 4.2019-November 8, 2019). www.NCCN.org, Gradishar et al in NCCN clinical practice guidelines in oncology (NCCN guidelines) breast cancer (Version 3.2019-September 6, 2019).www.NCCN.org). We report a patient with germline mutations in both BRCA2 and the MMR gene MLH1 who developed breast cancer. The breast cancer showed loss of heterozygosity (LOH) in BRCA2 (the molecular hallmark of cancers related to inheritance of a BRCA alteration) and was also deficient in mismatch repair gene protein expression (dMMR), the hallmark of LS-related cancers. We discuss the possible mechanisms of transformation that would explain the finding that the tumor showed both BRCA2 LOH and was dMMR, each of which would generally be considered a gatekeeper event for transformation of normal cells to malignancy. RESULTS: This report describes a patient with molecularly diagnosed breast and ovarian cancer syndrome (BRCA2) and LS. Next generation sequencing (NGS) and immunohistochemical (IHC) testing demonstrated her breast cancer to show BRCA2 LOH and to be dMMR. CONCLUSION: The patient presented represents the first reported case where both next generation sequencing (NGS) for BRCA LOH and MMR IHC testing of her breast cancer were performed and underscores the importance of using NGS including the reported mutational allelic frequency (MAF) and IHC use to predict the likely responsiveness to the recently approved PARP inhibitors and checkpoint inhibitor therapies (Robson et al in N Engl J Med 377:523-533, 2017, Lemery et al in 377(15):1409-1412, https://doi.org/10.1056/NEJMp1709968, 2017), key because the gatekeeper transforming event for tumors related to inherited cancer syndromes is loss of normal tumor suppressor gene (TSG) protein expression.
