Problems with attention and symptom distress are common clinical features reported by women who receive adjuvant chemotherapy for breast cancer. Mindfulness practice significantly improves attention and mindfulness programs significantly reduce symptom distress in patients with cancer, and, more specifically, in women with breast cancer. Recently, a pilot investigation of a music therapy program, built on core attitudes of mindfulness practice, reported significant benefits of enhanced attention ...[more]

Project description:OBJECTIVES:To analyze self-reported changes in physical function in older women with breast cancer receiving adjuvant chemotherapy. DESIGN:Secondary analysis of the Cancer and Leukemia Group B (CALGB) 49907 prospective randomized clinical trial. SETTING:CALGB institutions in the United States. PARTICIPANTS:Women aged 65 and older with Stage I to III breast cancer enrolled in CALGB 49907 who had physical function data from before and after receipt of adjuvant chemotherapy (N=256; mean age 71.5, range 65-85). MEASUREMENTS:Participants were administered the physical function subscale of the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire before chemotherapy, at the end of chemotherapy, and 12 months after chemotherapy initiation. Functional decline was defined as a more than 10-point decrease from baseline at each time point. Resilience was defined as return to within 10 points of baseline. Multivariable regression was used to examine pretreatment characteristics associated with physical function changes. RESULTS:Of 42% of participants who had physical function decline from before to the end of chemotherapy, 47% recovered by 12 months (were resilient). Almost one-third experienced functional decline from before chemotherapy to 12 months later. Pretreatment fatigue was a risk factor for functional decline from before to the end of chemotherapy (P=.02). Risk factors for functional decline at 12 months included pretreatment dyspnea (P=.007) and being unmarried (P=.01). CONCLUSION:Functional decline was common in older women receiving adjuvant chemotherapy for breast cancer in a clinical trial. Although half recovered their physical function, one-third had a clinically meaningful decline at 12 months. Strategies are needed to prevent functional decline in older adults receiving chemotherapy. J Am Geriatr Soc 67:920-927, 2019.

Project description:Large randomized trials assessing the benefit of adjuvant trastuzumab in early-stage breast cancer positive for the human epidermal growth factor receptor 2 (her2) have demonstrated a significant improvement in survival. The objective of the present study was to describe the outcomes of women who received adjuvant trastuzumab for her2-positive breast cancer in British Columbia since publicly funded population-based use was initiated in July 2005.Women from British Columbia, newly diagnosed with stage i-iii breast cancer between July 2004 and December 2006, who were positive for her2 overexpression by immunohistochemistry (3+) or amplification by fluorescence in situ hybridization (ratio ? 2.0) were included in the study. Data were collected from the prospectively assembled BC Cancer Agency Outcomes Unit, with cases linked to the provincial pharmacy data repository to determine the proportion of women who received adjuvant trastuzumab.Our retrospective study identified 703 her2-positive patients, of whom 480 (68%) received trastuzumab. In patients receiving trastuzumab, the 2-year relapse-free survival was 96.1% [95% confidence interval (CI): 93.6% to 97.7%] and the overall survival was 99.3% (95% CI: 97.9% to 99.8%). Among node-negative and -positive patients, the 2-year relapse-free survival was 97.8% and 94.8% respectively (p = 0.09) for the trastuzumab-treated group and 90.9% and 77.3% (p = 0.01) for the group not receiving trastuzumab (n = 223). Site of first distant metastasis was the central nervous system in 19.5% of the entire cohort and in 37.5% of patients treated with trastuzumab.This population-based analysis of adjuvant trastuzumab use among Canadian women demonstrates highly favorable outcomes at the 2-year follow-up.

Project description:BACKGROUND:Cognitive decline is among the most feared treatment-related outcomes of older adults with cancer. The majority of older patients with breast cancer self-report cognitive problems during and after chemotherapy. Prior neuroimaging research has been performed mostly in younger patients with cancer. The purpose of this study was to evaluate longitudinal changes in brain volumes and cognition in older women with breast cancer receiving adjuvant chemotherapy. METHODS:Women aged ??60 years with stage I-III breast cancer receiving adjuvant chemotherapy and age-matched and sex-matched healthy controls were enrolled. All participants underwent neuropsychological testing with the US National Institutes of Health (NIH) Toolbox for Cognition and brain magnetic resonance imaging (MRI) prior to chemotherapy, and again around one month after the last infusion of chemotherapy. Brain volumes were measured using Neuroreader™ software. Longitudinal changes in brain volumes and neuropsychological scores were analyzed utilizing linear mixed models. RESULTS:A total of 16 patients with breast cancer (mean age 67.0, SD 5.39 years) and 14 age-matched and sex-matched healthy controls (mean age 67.8, SD 5.24 years) were included: 7 patients received docetaxel and cyclophosphamide (TC) and 9 received chemotherapy regimens other than TC (non-TC). There were no significant differences in segmented brain volumes between the healthy control group and the chemotherapy group pre-chemotherapy (p?>?0.05). Exploratory hypothesis generating analyses focusing on the effect of the chemotherapy regimen demonstrated that the TC group had greater volume reduction in the temporal lobe (change?=?-?0.26) compared to the non-TC group (change?=?0.04, p for interaction?=?0.02) and healthy controls (change?=?0.08, p for interaction?=?0.004). Similarly, the TC group had a decrease in oral reading recognition scores (change?=?-?6.94) compared to the non-TC group (change?=?-?1.21, p for interaction?=?0.07) and healthy controls (change?=?0.09, p for interaction?=?0.02). CONCLUSIONS:There were no significant differences in segmented brain volumes between the healthy control group and the chemotherapy group; however, exploratory analyses demonstrated a reduction in both temporal lobe volume and oral reading recognition scores among patients on the TC regimen. These results suggest that different chemotherapy regimens may have differential effects on brain volume and cognition. Future, larger studies focusing on older adults with cancer on different treatment regimens are needed to confirm these findings. TRIAL REGISTRATION:ClinicalTrials.gov, NCT01992432 . Registered on 25 November 2013. Retrospectively registered.

Project description:As the number of older adults in the U.S. increases, so too will the incidence of cancer and cancer-related cognitive impairment (CRCI). However, the exact underlying biological mechanism for CRCI is not yet well understood. We utilized susceptibility-weighted imaging with quantitative susceptibility mapping, a non-invasive MRI-based technique, to assess longitudinal iron deposition in subcortical gray matter structures and evaluate its association with cognitive performance in women age 60+ with breast cancer receiving adjuvant chemotherapy and age-matched women without breast cancer as controls. Brain MRI scans and neurocognitive scores from the NIH Toolbox for Cognition were obtained before chemotherapy (time point 1) and within one month after the last infusion of chemotherapy for the patients and at matched intervals for the controls (time point 2). There were 14 patients age 60+ with breast cancer (mean age 66.3 ± 5.3 years) and 13 controls (mean age 68.2 ± 6.1 years) included in this study. Brain iron increased as age increased. There were no significant between- or within- group differences in neurocognitive scores or iron deposition at time point 1 or between time points 1 and 2 (p > 0.01). However, there was a negative correlation between iron in the globus pallidus and the fluid cognition composite scores in the control group at time point 1 (r = -0.71; p < 0.01), but not in the chemotherapy group. Baseline iron in the putamen was negatively associated with changes in the oral reading recognition scores in the control group (r = 0.74, p < 0.01), but not in the chemotherapy group. Brain iron assessment did not indicate cancer or chemotherapy related short-term differences, yet some associations with cognition were observed. Studies with larger samples and longer follow-up intervals are warranted.

Project description:BackgroundOlder women with breast cancer are underrepresented in clinical trials, and data on the effects of adjuvant chemotherapy in such patients are scant. We tested for the noninferiority of capecitabine as compared with standard chemotherapy in women with breast cancer who were 65 years of age or older.MethodsWe randomly assigned patients with stage I, II, IIIA, or IIIB breast cancer to standard chemotherapy (either cyclophosphamide, methotrexate, and fluorouracil or cyclophosphamide plus doxorubicin) or capecitabine. Endocrine therapy was recommended after chemotherapy in patients with hormone-receptor-positive tumors. A Bayesian statistical design was used with a range in sample size from 600 to 1800 patients. The primary end point was relapse-free survival.ResultsWhen the 600th patient was enrolled, the probability that, with longer follow-up, capecitabine therapy was highly likely to be inferior to standard chemotherapy met a prescribed level, and enrollment was discontinued. After an additional year of follow-up, the hazard ratio for disease recurrence or death in the capecitabine group was 2.09 (95% confidence interval, 1.38 to 3.17; P<0.001). Patients who were randomly assigned to capecitabine were twice as likely to have a relapse and almost twice as likely to die as patients who were randomly assigned to standard chemotherapy (P=0.02). At 3 years, the rate of relapse-free survival was 68% in the capecitabine group versus 85% in the standard-chemotherapy group, and the overall survival rate was 86% versus 91%. Two patients in the capecitabine group died of treatment-related complications; as compared with patients receiving capecitabine, twice as many patients receiving standard chemotherapy had moderate-to-severe toxic effects (64% vs. 33%).ConclusionsStandard adjuvant chemotherapy is superior to capecitabine in patients with early-stage breast cancer who are 65 years of age or older.

Project description:Weight gain and metabolic changes have been related to survival of early breast cancer patients (EBC). ''However, factors influencing metabolism post-diagnosis are not fully understood. We measured anthropometric [body mass index (BMI), body weight, waist and hip circumferences, and waist-to-hip ratio] and metabolic (levels of insulin, glucose, H1Ac, total, HDL, and LDL cholesterol, triglycerides, and the homeostasis model assessment score [HOMA]) parameters in 433 pre- and post-menopausal women with EBC at diagnosis and 3, 6, 9, 12, and 24 months thereafter. At diagnosis, compared with post-menopausal women, pre-menopausal patients were more likely to be leaner and to have a lower BMI, smaller waist and hip circumferences, and waist-to-hip ratio. They had also lower glucose, HbA1c, and triglyceride levels and a lower HOMA score. Furthermore, they were more likely to have an estrogen- and/or progesterone-positive tumor and a higher proliferating breast cancer. During the first two post-diagnosis years, all women showed a significant increase of weight (+0.72 kg/year, P < 0.001), waist circumference (+1.53 cm/year, P < 0.001), and plasma levels of LDL cholesterol (+5.4 mg/dl per year, P = 0.045) and triglycerides (+10.73 mg/dl per year, P = 0.017). In patients receiving chemotherapy only, there was a significant increase in hip circumference (+3.16 cm/year, P < 0.001) and plasma cholesterol levels (+21.26 mg/dl per year, P < 0.001). We showed that weight, body fat distribution, and lipid profile changed in EBC patients receiving adjuvant therapy. These changes occurred during the first 2 years after diagnosis and were not specifically related to chemotherapy, menopausal status, or initial body weight.

Project description:BackgroundAdjuvant chemotherapy benefits early-stage breast cancer (BC) patients. Older women receive guideline-adherent treatment less frequently and experience treatment delays more frequently. We evaluated factors associated with delaying adjuvant chemotherapy and the delays' survival impact in a large population-based cohort of elderly BC patients.MethodsPatients age >66 years diagnosed 2001-2015 with localized or regional BC were identified in the SEER-Medicare and Texas Cancer Registry-Medicare databases. Time from surgery to chemotherapy (TTC) was categorized into four groups: 0-30, 31-60, 61-90, and >90 days. We identified predictors of delays, estimated overall (OS) and BC-specific (BCSS) survival, and determined the association between TTC and outcome adjusting for other variables.ResultsAmong 28,968 women (median age 71 years), median TTC was 43 days. 10.7% of patients experienced TTC >90 days. Older age, Black or Hispanic race/ethnicity, unmarried status, more comorbidities, hormone receptor-positivity, mastectomy, Oncotype DX testing, and full state buy-in were associated with increased risk of delay. Five-year OS estimates by TTC group were 0.82, 0.81, 0.80, and 0.74, respectively (p<.001). BCSS demonstrated a similar trend (p<.001). Chemotherapy delay was associated with worse OS (HR=1.33, 95%CI 1.25-1.40) and BCSS (HR=1.39, 95%CI 1.27-1.53). In subgroup analysis, delayed chemotherapy was associated with worse OS and BCSS among patients with hormone receptor-positive (HR=1.56, 95%CI 0.97-2.51), HER2-positive (HR=1.99, 95%CI 1.04-3.79), and triple-negative (HR=2.15, 95%CI 1.38-3.36) tumors.ConclusionChemotherapy delays are associated with worse survival in older BC patients. Providers should avoid delays and initiate chemotherapy ≤90 days after surgery regardless of patients' BC subtype or age.

Project description:It is unknown whether racial differences exist in adjuvant chemotherapy initiation among women with similar oncotype DX (ODX) risk scores. We examined whether adjuvant chemotherapy initiation varied by race. Data come from the Phase III, Carolina Breast Cancer Study, a longitudinal, population-based study of North Carolina women diagnosed with breast cancer between 2008 and 2014. We used modified Poisson regression and report adjusted relative risk (aRR) and 95% confidence intervals (95%CI) to estimate the association between race and adjuvant chemotherapy initiation across ODX risk groups among women who received the test (n = 541). Among women who underwent ODX testing, 54.2, 37.5, and 8.3% of women had tumors classified as low-, intermediate-, and high-risk groups, respectively. We observed no racial variation in adjuvant chemotherapy initiation. Increasing ODX risk score (aRR = 1.39, 95%CI = 1.22, 1.58) and being married (aRR = 2.92, 95%CI = 1.12, 7.60) were independently associated with an increased likelihood of adjuvant chemotherapy in the low-risk group. Among women in the intermediate-risk group, ODX risk score (aRR = 1.15, 95%CI = 1.11, 1.20), younger age (aRR = 1.95, 95%CI = 1.35, 2.81), larger tumor size (aRR = 1.70, 95%CI = 1.22, 2.35), and higher income were independently associated with increased likelihood of adjuvant chemotherapy initiation. No racial differences were found in adjuvant chemotherapy initiation among women receiving ODX testing. As treatment decision-making becomes increasingly targeted with the use of genetic technologies, these results provide evidence that test results may drive treatment in a similar way across racial subgroups.

Project description:Factors associated with an increased risk of breast cancer include prior breast cancer, high circulating estrogens, and increased breast density. Adjuvant aromatase inhibitors are associated with a reduction in incidence of contralateral breast cancer. We conducted a prospective, single-arm, single-institution study to determine whether use of anastrozole is associated with changes in contralateral breast density and circulating estrogens. Eligible patients included postmenopausal women with hormone receptor-positive early-stage breast cancer who had completed local therapy, had an intact contralateral breast, and were recommended an aromatase inhibitor as their only systemic therapy. Participants received anastrozole 1 mg daily for 12 months on study. We assessed contralateral breast density and serum estrogens at baseline, 6, and 12 months. The primary endpoint was change in contralateral percent breast density from baseline to 12 months. Secondary endpoints included change in serum estrone sulfate from baseline to 12 months. Fifty-four patients were accrued. At 12 months, compared with baseline, there was a nonstatistically significant reduction in breast density (mean change: -16%, 95% CI: -30 to 2, P = 0.08) and a significant reduction in estrone sulfate (mean change: -93%, 95% CI: -94 to -91, P < 0.001). Eighteen women achieved 20% or greater relative reduction in contralateral percent density at 12 months compared with baseline; however, no measured patient or disease characteristics distinguished these women from the overall population. Large trials are required to provide additional data on the relationship between aromatase inhibitors and breast density and, more importantly, whether observed changes in breast density correlate with meaningful disease-specific outcomes.
