Survivorship care plans (SCP) are recommended for all cancer patients and could be especially useful to survivors 65 years and over ("older"). This study examined receipt of SCPs among older breast cancer survivors and whether SCPs were associated with improved patient-reported outcomes.Three hundred and twenty-eight older women diagnosed with invasive, nonmetastatic breast cancer between 2007-2011 were recruited from 78 cooperative-group sites. Participants completed telephone interviews at baseline and 1-year posttreatment. Regression analyses examined SCP receipt (yes/no) and functioning (EORTC-QLQ-C30), cancer worry, and experiences of survivorship care (care coordination, knowledge).Only 35% of women received SCPs. For each 1-year increase in age, there was a 5% lower odds of receiving an SCP (odds ratio (OR) = 0.94, 95% confidence interval (CI) 0.91-0.98, p = 0.007). Besides age, no other factor predicted SCPs. SCP receipt was associated with greater knowledge and understanding of requisite follow-up care (p 0.05); however, functioning was not significantly different among those with vs. without SCPs.Receipt of care plans was limited. SCPs improved understanding of breast cancer follow-up care among older survivors, but did not impact functioning one year post-treatment.To impact functioning and salient needs of the growing cohort of older survivors, survivorship care plans likely should be tailored to geriatric-specific issues. To improve functioning, SCP content should expand to include exercise, nutrition, polypharmacy, social support and management of symptom burden from cancer, and other comorbid conditions. To improve follow-up care for cancer survivors, SCPs should delineate shared care roles between oncology and primary care in managing recurrence surveillance, screening, and cancer sequelae.

Hormone receptor-positive (HR+) cancers account for most breast cancer diagnoses and deaths. Among survivors with HR + breast cancers, endocrine therapy (ET) reduces 5-year risk of recurrence by up to 40 %. Observational studies in Medicare- and privately-insured survivors suggest underutilization of ET. We sought to characterize ET use in a low-income Medicaid-insured population in North Carolina. Medicaid claims data were matched to state cancer registry records for survivors aging 18–64 diagnosed with stage 0–II HR + breast cancer from 2003 to 2007, eligible for ET, and enrolled in Medicaid for at least 12 of 15 months post-diagnosis. We used multivariable logistic regression to model receipt of any ET medication during 15 months post-diagnosis controlling for age, race, tumor characteristics, receipt of other treatments, comorbidity, residence, reason for Medicaid eligibility, involvement in the Breast and Cervical Cancer Control Program (BCCCP), and diagnosis year. Of 222 women meeting the inclusion criteria, only 50 % filled a prescription for ET. Involvement in the BCCCP and earlier year of diagnoses were associated with significantly higher odds of initiating guideline-recommended ET (adjusted odds ratio [AOR] for the BCCCP 3.76, 95 % confidence interval [CI] 1.67–8.48; AOR for 2004 relative to 2007 2.80, 95 % CI 1.03–7.62; AOR for 2005 relative to 2007 2.11, 95 % CI 0.92–4.85). Results suggest substantial underutilization of ET in this population. Interventions are needed to improve timely receipt of ET and to better support survivors taking ET. Low-income survivors should be counseled on the importance of ET and offered support services to promote initiation and long-term adherence.

Breast cancer is predominantly a disease of older women, yet there is a knowledge gap due to the persisting misalignment between the age distribution of women with breast cancer and the age distribution of participants in clinical trials. The purpose of this report is to state the U13 conference breast cancer panel’s recommendations regarding therapeutic clinical trials that will fill gaps in knowledge regarding the care of older patients with breast cancer. The U13 conference was a collaboration between the Cancer and Aging Research Group and the National Institute on Aging and the National Cancer Institute (NCI). Clinical trials should be developed for frail and vulnerable patients who would not enroll on the standard phase III trials, as well as efforts need to be made to increase enrollment of fit older patients on standard phase III trials. As a result of this conference, panel members are working with the NCI and cooperative groups to address these knowledge gaps. With the aging population and increasing incidence of breast cancer with age, it is essential to study the feasibility, toxicity, and efficacy of cancer therapy in this at-risk population.

Purpose: The purpose of this study was to examine how the cultural factors, stigma, being strong, and religiosity influence symptom distress in African American cancer survivors. Methods: This descriptive correlational study was designed using the Sociocultural Stress and Coping Framework. Seventy-seven African American cancer survivors, recruited from oncology clinics and the community in North Carolina, completed a questionnaire that consisted of measures of demographic and illness characteristics, the Perceived Stigma Scale, the Ways of Helping Questionnaire, the Religious Involvement Scale, and the Symptom Distress Scale. Results: The two cultural factors that were significantly associated with symptom distress were stigma (β = .23, p < .05) and organized religion (β = −.50, p < .05). No significant associations were found between being strong or nonorganized religiosity and symptom distress. The most commonly reported symptoms were fatigue ( M = 2.44, SD = 1.20), pain ( M = 2.26, SD = 1.43), and insomnia ( M = 1.95, SD = 1.25). Conclusions: The findings of this study indicate that the cultural factors, stigma, and organized religiosity were significantly associated with symptom distress. Implications for Practice: The results from this study can be used to guide researchers in developing culturally appropriate interventions aimed at alleviating symptom distress in African American cancer survivors.

BACKGROUND Health care providers have little population-based evidence about health-related quality of life (HRQOL) changes, from the pre- to postdiagnosis period, and treatment-related recovery time for women aged 65 years and older diagnosed with breast cancer. METHODS Older women with and without breast cancer completed self-reports of HRQOL at baseline and 2 years later as part of annual Medicare Health Outcomes Surveys (MHOS). MHOS was linked to Surveillance, Epidemiology, and End Results registries, which were used to categorize women with breast cancer by treatment type (breast-conserving surgery, breast-conserving surgery plus radiation, mastectomy) and time since diagnosis at follow-up. Each cancer case diagnosed in 1998 through 2007 (N = 542) was matched to 5 women without cancer (N = 2710) using propensity score matching. Analysis of covariance models examined changes in HRQOL, adjusting for demographics and initial functioning. RESULTS Older women within 6 months of diagnosis had greater declines than women without cancer in SF-36 Physical (−5.8 vs −1.8) and Mental (−3.6 vs −0.7) Component Summary scores, General Health (−12.3 vs −4.6), Vitality (−11.0 vs −2.2), Bodily Pain (−8.5 vs −2.1), Social Functioning (−15.1 vs −3.3), Role-Physical (−26.5 vs −3.9), and Role-Emotional (−13.1 vs −3.1) scores (all P

e18132 Background: Older adults (65+ years) make up > 50% of cancer patients in the US,1 yet, older patient enrollment onto trials remains < 30%.2 This study’s aim was to determine the association between trial level variables and accrual rates of adults 65+ to better design trials that can more improve enrollment of these patients. Methods: We analyzed enrollment percentages of patients age 65+ in non-age specific Alliance trials with > 50 patients, that completed accrual between 1995- 2015. Enrollment percentage by 65+ for each study was compared to cancer incidence percentage by 65+ according to the Surveillance, Epidemiology, and End Results (SEER) Program for the same time periods. Enrollment Disparity Difference (EDD)3, defined as the difference between SEER incidence percentage of patients 65+ and the trial percentage enrollment of 65+ was calculated for each trial ( SEER % – trial %). Univariate analyses (UVA) were performed using simple linear regression to determine trial variables associated with larger EDDs (higher disparity). Variables that had an F-test p-value < 0.20 were included in a multivariable fixed-effects linear model for multivariate analysis (MVA). Results: Median age of 66,708 patients across 237 trials with 10 cancer types was 60 years. Average % of 65+ in trials was lower than average SEER comparison % 65+ per trial (37.6% vs. 57.8%). The median trial EDD, was 16.7%. On UVA, cancer type was significantly associated with higher EDD (see Table). Use of fewer modalities (1, 2, vs 3+) was associated with lower estimated EDDs (1 = -11 [+/-3.6], 2 = -8.9 [+/-3.9], F-test p = .012). On MVA, non-genitourinary (GU) cancer type, number of treatment modalities, and the phase (II or III compared to observational/other) were all significantly associated with higher EDD. Conclusions: Older adults were under-represented in this large sample of trials. This information can be used as a platform to better design disease-specific trials to improve older patient accrual, particularly in disease areas which are under-performing.

Background: Older pts with BC receiving adjuvant tx are at increased risk of chemo tox; however, no BC-specific tool exists to quantify this risk. The Cancer and Aging Research Group (CARG) developed/validated a chemo tox score for older pts with all stages of solid tumor. The goals of this study were to: 1) build upon the CARG score by developing/validating CARG-BC (a BC specific adjuvant chemo tox score for older pts) and 2) evaluate its association with dose modifications, reduced relative dose intensity (RDI) and hospitalizations. Methods: 501 pts age ≥65 with stage I-III BC from 16 sites were accrued (300 development; 201 validation cohort). A pre-chemo assessment captured: CARG chemo tox score, BC tumor/tx variables, and additional geriatric assessment (GA) items. Grade 3-5 chemo tox by NCI CTCAE v 4.0 was captured. Univariate analysis identified chemo tox risk factors (p Results: Among 501 pts, 28 received non-standard regimens and were excluded, leaving 473 evaluable pts: 283 development and 190 validation cohort. The development cohort (median age 70; range 65-85) had Stage I (39%), II (41%), & III (20%) BC with 65% hormone positive, 24% triple negative, 27% Her2 positive; and 37% received an anthracycline. Grade 3-5 tox occurred in 46% (36% grade 3, 10% grade 4, 0.4% grade 5). The CARG score was significantly associated with grade 3-5 tox (p Conclusions: We developed and validated a risk score (CARG-BC) which identifies an older pt's risk for adjuvant BC chemo tox and is associated with dose reduction, delay, reduced RDI, and hospitalization. This tool could be considered as a part of adjuvant tx decision-making.

Background: Increased expression of p16INK4a, a molecular marker of aging, is a hallmark of increased cellular senescence in most mammalian tissues. In human peripheral blood T-lymphocytes, expression of p16INK4a increases 10-fold between 20 and 80 years of age (Liu et al, Aging Cell, 2009). We hypothesized that higher "molecular age," as evidenced by increased T-cell expression of p16INK4a at the time of initiation of breast cancer (BC) chemotherapy (CRx), predicts increased treatment-related toxicity. Methods: Patients (pts) with early breast cancer scheduled to receive neoadjuvant (NA) or adjuvant (Adj) chemotherapy (CRx) had p16INK4a evaluation performed prior to treatment. Expression of p16INK4a mRNA in CD3+ T-lymphocytes was determined using TaqMan real time quantitative reverse transcription polymerase chain reaction. Grade 3 and 4 (G3/4) hematologic (H) and non-hematologic (NH) toxicities (NCI CTCAE version 4) were assessed during and within 4 weeks of completion of CRx. Wilcoxon Rank Sum tests compared p16INK4a between groups. Results: 93 pts with Stage I-III BC and complete toxicity data during and within 4 weeks after completion of CRx have been accrued. Median age (range) was 52 (25-76). 48 (52%) of pts were hormone receptor (HR) positive, 21 (23%) HER-2 positive, and 24 (26%) triple-negative. 39 (42%) received NA and 54 (58%) received Adj CRx. 57 pts (61%) received an anthracycline containing combination and 21 (23%) cyclophosphamide/docetaxel (TC). 85 pts (91%) received pegfilgrastim. Overall, 69 pts (74%) had a G3/4 toxicity during or ≤4 wks of CRx, 54% NH and 40% H. 22 pts (24%) were hospitalized for CRx related toxicity and 11 (12%) of these admissions were for neutropenic fever (NF). 23 (25%) reported G3/4 fatigue during CRx and had significantly higher p16INK4a values at baseline than those without fatigue (p=0.03). There was no significant association of baseline p16INK4a and other NH or H toxicity or hospitalization in this cohort. Conclusion: In this small sample of pts treated with anthracycline and non-anthracycline containing NA and Adj CRx regimens, there was a significant association of baseline p16INK4a and G3/4 fatigue. The heterogeneity of treatment and use of pegfilgrastim in almost all pts limits the power of this study to find significant relationships between p16INK4a and other toxicities. The cohort for this study is being expanded to further explore p16INK4a as a predictor for G3/4 toxicity.

Background: Most breast cancer cases diagnosed among postmenopausal women are hormone receptor positive (HR+); standard adjuvant endocrine treatment usually includes an aromatase inhibitor (AI). Joint pain/stiffness/achiness (arthralgia) is a common AI side-effect, and AI discontinuation due to this side-effect is an estimated 20-32%. There is a need for effective alternative or adjunctive approaches to arthralgia management that enable survivors to remain on AI therapy while optimizing as pain-free a life as possible. This pilot study investigates the feasibility of a highly scalable 6-week self-directed physical activity (PA) program – Walk With Ease (WWE) – among elderly female breast cancer survivors on AIs who report joint pain. WWE goal: minimum of 30 minutes of walking 5 days a week (150 minutes/week). Methods: Recruitment: BC survivors age 65+ were recruited through the oncology clinic of a university-affiliated hospital. Eligibility: age 65+; Stage I-III breast cancer; currently on AI therapy; self-reported joint pain/stiffness; physician permission to engage in PA; English speaking. Measures: (1) walking – number of days per week and number of minutes per walk, (2) visual analog scales (VAS) for joint pain, fatigue and stiffness, and (3) arthritis self-efficacy (ASE) to manage joint pain and fatigue. Statistics: t-test evaluation of changes in mean values. Results: Sample (N = 20) – mean age 71 (65-87), 85% Caucasian, 35% < high school, mean BMI 29. 63% chemotherapy, 61% radiation therapy. 90% completed the 6-week intervention. Compared to baseline, total minutes of walking per week increased from 95 (0-450) to 172 (45-700) (p Conclusions: A moderate-intensity self-directed walking program is feasible for older breast cancer patients on AI therapy and almost doubled the total time of walking per week over a 6 week period. Joint pain, stiffness, and fatigue decreased, and the walking program was perceived as informative and motivational. These data are promising and the WWE intervention warrants testing in a larger randomized trial of breast cancer survivors on AI therapy.

Objectives Patients ≥ 65 years old (“older”) are often not included in randomized clinical trials (RCT), but when they are, care in an RCT might improve quality of life (QoL). We conducted a prospective comparison of QoL among older women receiving standard chemotherapy from the same cooperative group physicians in an RCT vs. an observational study (“off-trial”). Methods Older women with invasive, non-metastatic breast cancer (n = 150 RCT; 530 off-trial) were included. Linear mixed-effects models tested associations between chemotherapy on- vs. off-trial and changes in EORTC (European Organisation for Research and Treatment of Cancer Quality of Life Questionnaire) QoL scores over 24 months, controlling for pre-treatment QoL, age, education, tumor factors, comorbidity, and other covariates. Results Anthracycline regimens were used by 58% of women treated on-trial vs. 54% of those treated off-trial. Women in the RCT reported an adjusted mean increase of 13.7 points (95% CI 10.2, 17.1) in global QoL at 24 months (vs. mid-treatment), while women treated off-trial had only an adjusted improvement of 7.0 points (95% CI 3.5, 10.4; p = .007 for difference in mean changes). Women in the RCT had significantly greater improvement in emotional function than those treated off-trial, controlling for baseline; they also had greater reductions in therapy side effects and fatigue at 24 months than women off-trial, controlling for covariates. Conclusion There may be different QoL trajectories for older women undergoing breast cancer chemotherapy on- vs. off-trial. If confirmed, the results suggest that the extra monitoring and communication within an RCT could provide the infrastructure for interventions to address symptoms and improve QoL for the growing older cancer population.

Patients with hormone receptor–positive early breast cancer have a continuous yearly rate of recurrence extending out to 15 years after having received adjuvant endocrine therapy with tamoxifen for 5 years (1). More than half of the recurrences and about two-thirds of breast cancer deaths in this group will occur beyond 5 years from diagnosis (ie, late recurrences and death) (1). The National Cancer Institute of Canada (NCIC) Clinical Trials Group MA.17 trial was a randomized, placebo-controlled trial demonstrating that extended endocrine therapy with letrozole improves disease-free survival (DFS) (2), distant DFS (DDFS), and overall survival (OS) in disease-free postmenopausal patients with hormonal receptor–positive breast cancer after 5 years of tamoxifen (3). Although extended antihormonal therapy has become standard practice and is endorsed by international clinical practice guidelines (4,5), understanding which patients will actually benefit from longer treatment is paramount to individualized therapy. The status of primary tumor estrogen receptor (ER) and progesterone receptor (PR) expression has been suggested, but not confirmed, as a way to identify patients who have increased benefit from extended letrozole (5). Patients with ER+ and PR+ tumors have been shown to have improved DFS (P = .02) when compared with patients with ER+ and PR− tumors (6). Currently, however, there are no guideline-accepted biomarkers to stratify hormonal receptor–positive patients for prediction of benefit beyond the 5 years of adjuvant endocrine therapy. In addition, standard clinico-pathological factors and clinically available genomic signatures, including the 21-gene (Recurrence Score) assay (7) and the 70-gene assay (8), have greatest prognostic performance for recurrence risk within the first 5 years of adjuvant therapy. Identification of additional biomarkers to further stratify hormone receptor–positive tumors to predict those at risk of late recurrence and those who may or may not benefit from extended endocrine therapy would be of substantial clinical utility (9). We have previously demonstrated that the two-gene expression ratio, HOXB13/IL17BR (H/I), is a prognostic biomarker in both untreated and tamoxifen-treated early-stage ER+ breast cancer patients (10–13). However, potential assessment of H/I as a predictive biomarker for endocrine therapy has been limited by the analysis of retrospective/observational cohorts or by the use of single treatment arm cohorts from randomized trials (11–13). Herein, we have conducted a prospective–retrospective (14), nested case-control study in a subset of patients from NCIC Clinical Trials Group MA.17 trial to evaluate the performance of H/I for 1) prognostication of late disease recurrence and 2) prediction of treatment benefit from extended adjuvant letrozole therapy in patients with hormone receptor–positive early breast cancer.

Purpose To determine whether psychosocial factors predict depression among older African American cancer patients.

Cognitive changes in older women receiving chemotherapy are poorly understood. We examined self-reported cognitive function for older women who received adjuvant chemotherapy on Cancer and Leukemia Group B (CALGB) 49907. CALGB 49907 randomized 633 women aged ≥65 with stage I–III breast cancer to standard adjuvant chemotherapy (cyclophosphamide–methotrexate–5-fluoro-uracil or doxorubicin–cyclophosphamide) versus capecitabine. We examined self-reported cognitive function in 297 women (CALGB 361002) who enrolled on the quality of life substudy and had no gross impairment on cognitive screening. Women were evaluated using an 18-item instrument at six time points (baseline through 24 months). At each time point for each patient, we calculated a cognitive function score (CFS) defined as the mean response of items 1–18 and defined impairment as a score >1.5 standard deviations above the overall average baseline score. Differences in scores by patient characteristics were evaluated using a Kruskal–Wallis test. A linear mixed-effects model was used to assess CFSs by treatment over time. Among 297 women, the median age was 71.5 (range 65–85) and 73 % had performance status of 0. Baseline depression and fatigue were reported in 6 and 14 % of patients, respectively. The average CFS at baseline was 2.08 (corresponding to “normal ability”), and baseline cognitive function did not differ by treatment regimen (p = 0.350). Over 24 months, women reported minimal changes at each time point and insignificant differences by treatment arm were observed. In a healthy group of older women, chemotherapy was not associated with longitudinal changes in self-reported cognitive function.

Aspirin has a range of antineoplastic properties linked to inhibition of cyclooxygenase enzymes in tumor cells, platelet inhibition and to inhibition of angiogenesis. We undertook a prospective study to determine the influence of a 45‐day course of aspirin therapy on circulating and intraplatelet levels of selected proangiogenic (vascular endothelial growth factor [VEGF]) and antiangiogenic (thrombospondin‐1 [TSP‐1]) proteins, and platelet protein release in women diagnosed with breast cancer who were receiving tamoxifen therapy. Initiation of aspirin therapy increases serum and intraplatelet levels of TSP‐1 without a corresponding increase in VEGF levels. Following aspirin therapy, VEGF levels decreased (relative to pretreatment levels) while TSP‐1 returned to pretreatment levels. Plasma TSP‐1 and VEGF levels did not change on aspirin therapy. Aspirin use also decreased thrombin receptor mediated release of TSP‐1 and VEGF from platelets. The selective impact on platelet angiogenic protein content and release supports one mechanism by which aspirin can modify the angiogenic balance in women receiving tamoxifen therapy. Aspirin therapy appears to favor an overall antiangiogenic balance in women with breast cancer who are receiving tamoxifen therapy.

Purpose To provide recommendations on the follow-up and management of patients with breast cancer who have completed primary therapy with curative intent. Methods To update the 2006 guideline of the American Society of Clinical Oncology (ASCO), a systematic review of the literature published from March 2006 through March 2012 was completed using MEDLINE and the Cochrane Collaboration Library. An Update Committee reviewed the evidence to determine whether the recommendations were in need of updating. Results There were 14 new publications that met inclusion criteria: nine systematic reviews (three included meta-analyses) and five randomized controlled trials. After its review and analysis of the evidence, the Update Committee concluded that no revisions to the existing ASCO recommendations were warranted. Recommendations Regular history, physical examination, and mammography are recommended for breast cancer follow-up. Physical examinations should be performed every 3 to 6 months for the first 3 years, every 6 to 12 months for years 4 and 5, and annually thereafter. For women who have undergone breast-conserving surgery, a post-treatment mammogram should be obtained 1 year after the initial mammogram and at least 6 months after completion of radiation therapy. Thereafter, unless otherwise indicated, a yearly mammographic evaluation should be performed. The use of complete blood counts, chemistry panels, bone scans, chest radiographs, liver ultrasounds, pelvic ultrasounds, computed tomography scans, [18F]fluorodeoxyglucose–positron emission tomography scans, magnetic resonance imaging, and/or tumor markers (carcinoembryonic antigen, CA 15-3, and CA 27.29) is not recommended for routine follow-up in an otherwise asymptomatic patient with no specific findings on clinical examination.

MA17 showed improved outcomes in postmenopausal women given extended letrozole (LET) after completing 5 years of adjuvant tamoxifen.Exploratory subgroup analyses of disease-free survival (DFS), distant DFS (DDFS), overall survival (OS), toxic effects and quality of life (QOL) in MA17 were performed based on menopausal status at breast cancer diagnosis.At diagnosis, 877 women were premenopausal and 4289 were postmenopausal. Extended LET was significantly better than placebo (PLAC) in DFS for premenopausal [hazard ratio (HR) = 0.26, 95% confidence interval (CI) 0.13-0.55; P = 0.0003] and postmenopausal women (HR = 0.67; 95% CI 0.51-0.89; P = 0.006), with greater DFS benefit in those premenopausal (interaction P = 0.03). In adjusted post-unblinding analysis, those who switched from PLAC to LET improved DDFS in premenopausal (HR = 0.15; 95% CI 0.03-0.79; P = 0.02) and postmenopausal women (HR = 0.45; 95% CI 0.22-0.94; P = 0.03).Extended LET after 5 years of tamoxifen was effective in pre- and postmenopausal women at diagnosis, and significantly better in those premenopausal. Women premenopausal at diagnosis should be considered for extended adjuvant therapy with LET if menopausal after completing tamoxifen.

The aim of this study was to examine the association of Computerized Tomography (CT) assessed skeletal muscle measures with physical function in older adults with cancer. Results: CTs for 185 patients were available. Median age 73 (IQR 68–76) and 56.5% female. After controlling for sex and BMI, we found no evidence that SMI was associated with physical function impairments. Both SMD and SMG were associated physical function impairments and higher values were associated with decreased limitations in instrumental activities of daily living (RR 0.84 [CI 0.73–0.96] and 0.94 [CI 0.89–0.99], respectively), climbing stairs (RR 0.84 [CI 0.76–0.94] and 0.91 [CI 0.87–0.96]), walking 1 block (RR 0.77 [CI 0.67–0.90] and 0.91 [CI 0.85–0.97]), and prolonged Timed Up and Go (RR 0.83 [CI 0.75–0.92] and 0.92 [CI 0.88–0.96]). Materials and Methods: Using the Carolina Senior Registry, we identified patients with CT imaging performed within 60 days +/− of baseline geriatric assessment (GA). Skeletal muscle area and density (SMD) were analyzed from L3 lumbar segments. Muscle area and height (m 2 ) were used to calculate skeletal muscle index (SMI). Skeletal Muscle Gauge (SMG) was created by multiplying SMI x SMD. Conclusions: Skeletal muscle mass as assessed from CT imaging was not associated with physical function impairments. Skeletal muscle radiodensity was more associated with physical function and may aid in identifying older adults at risk for functional impairments.

Background: An objective measure is needed to identify frail older adults with cancer who are at increased risk for poor health outcomes. The primary objective of this study was to develop a frailty index from a cancer-specific geriatric assessment (GA) and evaluate its ability to predict all-cause mortality among older adults with cancer. Patients and Methods: Using a unique and novel data set that brings together GA data with cancer-specific and long-term mortality data, we developed the Carolina Frailty Index (CFI) from a cancer-specific GA based on the principles of deficit accumulation. CFI scores (range, 0-1) were categorized as robust (0-0.2), pre-frail (0.2-0.35), and frail (>0.35). The primary outcome for evaluating predictive validity was all-cause mortality. The Kaplan-Meier method and log-rank tests were used to compare survival between frailty groups, and Cox proportional hazards regression models were used to evaluate associations. Results: In our sample of 546 older adults with cancer, the median age was 72 years, 72% were women, 85% were white, and 47% had a breast cancer diagnosis. Overall, 58% of patients were robust, 24% were pre-frail, and 18% were frail. The estimated 5-year survival rate was 72% in robust patients, 58% in pre-frail patients, and 34% in frail patients (log-rank test, P

Platelets and their granular contents influence both angiogenesis and breast cancer progression. This study was performed to assess the effect of breast cancer and its treatment on platelet biology and the response to inhibition of the platelet P2Y12 receptor. Receptor-specific platelet activation and inhibition was studied for three platelet-associated proteins important in cancer angiogenesis and progression, vascular endothelial growth factor (VEGF), thrombospondin1 (TSP1), and transforming growth factor beta 1 (TGF-β1). Twenty-four women with active breast cancer and 10 healthy controls not receiving antiplatelet therapy participated in the study. Ex vivo activation of platelets in whole blood was accomplished using PAR1AP, PAR4AP, convulxin, and ADP. Platelet inhibition was accomplished using the P2Y12 receptor antagonist cangrelor (the in vitro equivalent of clopidogrel). VEGF, TSP1, and TGF-β1 were measured using standard ELISA. Platelet activation by ADP, PAR1, PAR4, and collagen receptors increased VEGF, TSP1, and TGF-β1 secretion in patients with breast cancer. Agonist-induced release of VEGF was greater in cancer patients as compared to healthy controls (p = 0.02 for ADP, p < 0.001 for PAR1AP, PAR4AP, and convulxin) despite a decrease in the efficiency of VEGF secretion in patients with breast cancer. These differences were not observed for TSP1 and TGF-β1 secretion. P2Y12 receptor inhibition decreased VEGF, TSP1, and TGF-β1 secretion. In patients with cancer, cangrelor inhibited TSP1 release to a greater extent than VEGF and TGF-β1 release. In patients with breast cancer, the magnitude of platelet inhibition achieved by cangrelor was greater than that achieved with healthy controls for all agonists and platelet proteins studied. While platelets are known to influence progression of breast cancer, our results show that breast cancer and its treatment influence the platelet phenotype by increasing the secretion of pro-angiogenic proteins following platelet activation, modulating the efficiency of platelet protein release as well as increasing the response to antiplatelet therapy.

The development of a more robust observational research data infrastructure would help to address gaps in the evidence base regarding optimal approaches to treating cancer among the growing and complex population of older adults. To demonstrate the feasibility of building such a resource, information from a sample of older adults with cancer was linked using three distinct but complementary data sources. Results are reported to highlight the potential for data linkage to improve the characterization of health status among older adults with cancer and the possibility to conduct passive follow‐up for outcomes of interest over time., Older adults (aged 65 years and older) diagnosed with cancer account for most cancer‐related morbidity and mortality in the United States but are often underrepresented on clinical trials. Recent attention from a variety of professional, research, regulatory, and patient advocacy groups has centered on data linkage and data sharing as a means to capture patient information and outcomes outside of clinical trials to accelerate progress in the fight against cancer. The development of a more robust observational research data infrastructure would help to address gaps in the evidence base regarding optimal approaches to treating cancer among the growing and complex population of older adults. To demonstrate the feasibility of building such a resource, we linked information from a sample of older adults with cancer in North Carolina using three distinct, but complementary, data sources: (a) the Carolina Senior Registry, (b) the North Carolina Central Cancer Registry, and (c) North Carolina fee‐for‐service Medicare claims data. A description of the linkage process, metrics, and characteristics of the final cohort is reported. This study highlights the potential for data linkage to improve the characterization of health status among older adults with cancer and the possibility to conduct passive follow‐up for outcomes of interest over time. Extensions of these linkage efforts in partnership with other institutions will enhance our ability to generate evidence that can inform the management of older adults with cancer.

Purpose To develop recommendations about endocrine therapy for women with hormone receptor (HR) –positive metastatic breast cancer (MBC). Methods The American Society of Clinical Oncology convened an Expert Panel to conduct a systematic review of evidence from 2008 through 2015 to create recommendations informed by that evidence. Outcomes of interest included sequencing of hormonal agents, hormonal agents compared with chemotherapy, targeted biologic therapy, and treatment of premenopausal women. This guideline puts forth recommendations for endocrine therapy as treatment for women with HR-positive MBC. Recommendations Sequential hormone therapy is the preferential treatment for most women with HR-positive MBC. Except in cases of immediately life-threatening disease, hormone therapy, alone or in combination, should be used as initial treatment. Patients whose tumors express any level of hormone receptors should be offered hormone therapy. Treatment recommendations should be based on type of adjuvant treatment, disease-free interval, and organ function. Tumor markers should not be the sole criteria for determining tumor progression; use of additional biomarkers remains experimental. Assessment of menopausal status is critical; ovarian suppression or ablation should be included in premenopausal women. For postmenopausal women, aromatase inhibitors (AIs) are the preferred first-line endocrine therapy, with or without the cyclin-dependent kinase inhibitor palbociclib. As second-line therapy, fulvestrant should be administered at 500 mg with a loading schedule and may be administered with palbociclib. The mammalian target of rapamycin inhibitor everolimus may be administered with exemestane to postmenopausal women with MBC whose disease progresses while receiving nonsteroidal AIs. Among patients with HR-positive, human epidermal growth factor receptor 2–positive MBC, human epidermal growth factor receptor 2–targeted therapy plus an AI can be effective for those who are not chemotherapy candidates.

Purpose To evaluate the association between functional status based on a geriatric assessment (GA) and outcomes of tolerance to treatment in patients with lung or head and neck cancer receiving radiation therapy (RT) or chemoradiation (CRT). Methods and Materials A prospective cohort study was conducted in patients aged ≥65 years with head and neck cancer or lung cancer undergoing curative intent RT or CRT. Pretreatment GA, health-related quality of life (HRQoL), and patient-reported outcomes (PRO) were obtained. Questionnaires were repeated biweekly during RT and at 6 weeks after treatment. Dysfunction was defined as scores 3-day treatment delay, change in RT or CRT regimen, or death. Associations of dysfunction with tolerance to radiation therapy, HRQoL changes, and PRO ratings were evaluated. Results Of the 50 patients accrued, 46 had evaluable data. Mean age was 72.5 years (range, 65-92 years). At baseline, 37% had dysfunction. Poor tolerance to RT or CRT occurred in 39%. There was no association between dysfunction and tolerance. Patients with dysfunction had lower baseline HRQoL scores. From baseline to end of RT, those with baseline dysfunction had less of a decline in Role Functioning (P=.01) and Global Health Score (P=.04) domains. However, from end of RT to 6-week follow-up, those with dysfunction were more likely to continue to drop in the Physical, Role Functioning, and Social domains (all P

An accumulating body of evidence supports the hypothesis that cancer and/or cancer treatment is associated with accelerated aging. The majority of these data come from the pediatric literature; however, a smaller yet growing body of literature points toward similar findings in the geriatric population. This is a key survivorship issue the growing number of older adults with cancer face, along with the short- and long-term impact of cancer therapy on the aging process. This article will review clinical and biologic markers of aging in older adults with cancer, use cardiovascular disease as a model of accelerated aging, and discuss potential interventions to decrease the risk.

Purpose Older adults are at increased risk for chemotherapy toxicity, and standard oncology assessment measures cannot identify those at risk. A predictive model for chemotherapy toxicity was developed (N = 500) that consisted of geriatric assessment questions and other clinical variables. This study aims to externally validate this model in an independent cohort (N = 250). Patients and Methods Patients age ≥ 65 years with a solid tumor, fluent in English, and who were scheduled to receive a new chemotherapy regimen were recruited from eight institutions. Risk of chemotherapy toxicity was calculated (low, medium, or high risk) on the basis of the prediction model before the start of chemotherapy. Chemotherapy-related toxicity was captured (grade 3 [hospitalization indicated], grade 4 [life threatening], and grade 5 [treatment-related death]). Validation of the prediction model was performed by calculating the area under the receiver-operating characteristic curve. Results The study sample (N = 250) had a mean age of 73 years (range, 65 to 94 [standard deviation, 5.8]). More than one half of patients (58%) experienced grade ≥ 3 toxicity. Risk of toxicity increased with increasing risk score (36.7% low, 62.4% medium, 70.2% high risk; P < .001). The area under the curve of the receiver-operating characteristic curve was 0.65 (95% CI, 0.58 to 0.71), which was not statistically different from the development cohort (0.72; 95% CI, 0.68 to 0.77; P = .09). There was no association between Karnofsky Performance Status and chemotherapy toxicity (P = .25). Conclusion This study externally validated a chemotherapy toxicity predictive model for older adults with cancer. This predictive model should be considered when discussing the risks and benefits of chemotherapy with older adults.

Internet tools have become a great aid in the daily practice of physicians who treat breast cancer patients. In cancer care there are frequent and important intersections where major decisions need to be made; these include (1) whether or not to give chemotherapy; (2) how much toxicity to expect, and (3) the life expectancy of the patient, considering non-breast cancer comorbidities. These decisions can be made more accurately using calculators based on data sets of thousands of patients as opposed to physician intuition. Such tools also help patients and caregivers in optimal decision making, as they estimate the absolute benefits and risks of treatment. In this perspective we describe selected internet sites that are useful across several domains of care, including the potential benefits of different adjuvant regimens for early breast cancer, prognosis after neoadjuvant therapy, prognosis for ductal carcinoma in situ, and toxicity and life expectancy estimates. We review the variables required to use the tools, the results obtained, the methods of validation, and the advantages and disadvantages of each tool.

Purpose: Severe skeletal muscle (SM) loss (sarcopenia) is associated with poor cancer outcomes, including reduced survival and increased toxicity. This study investigates SM measures in metastatic breast cancer (MBC) patients receiving first-line taxane-based chemotherapy and evaluates associations with treatment toxicity and other outcomes. Experimental Design: Using computerized tomography (CT) images taken for the evaluation of disease burden, skeletal muscle area (SMA), and density (SMD) were measured at the third lumbar vertebrae. Sarcopenia was defined as skeletal muscle index (SMI = SMA/height2) ≤ 41. Skeletal muscle gauge (SMG) was created by multiplying SMI × SMD. Fisher exact tests, t tests, the Kaplan–Meier method, and Cox regression modeling were used. Results: MBC patients (N = 40), median age 55 (range, 34–80), 58% sarcopenic, median SMG 1296 AU (SD, 522). Grade 3–4 toxicity was found in 57% of sarcopenic versus 18% of non-sarcopenic patients (P = 0.02). Toxicity-related hospitalizations were also higher in sarcopenic patients (39% vs. 0%, P = 0.005) as were any adverse events—defined as any grade 3–4 toxicities, hospitalizations, dose reductions, or dose delay—(74% vs. 35%, P = 0.02). Low SMG was associated with grade 3–4 toxicity (P = 0.04), hospitalization (P = 0.01), and time to treatment failure (for progression or toxicity; P = 0.03). Low SMG had a borderline significant association with any adverse event (P = 0.06) and overall survival (P = 0.07). Conclusions: SM measures are associated with toxicity outcomes and survival in MBC patients receiving first-line taxane-based chemotherapy. Further studies are needed to explore how routinely obtained CT scans can be used to individualize dosing and improve treatment planning. Clin Cancer Res; 23(3); 658–65. ©2016 AACR.

Baseline patient and tumor characteristics differentially affected type of death in the MA.17 placebo-controlled letrozole trial where cardiovascular death was not separately identified. The MA.27 trial allowed competing risks analysis of breast cancer (BC), cardiovascular, and other type (OT) of death. MA.27 was a phase III adjuvant breast cancer trial of exemestane versus anastrozole. Effects of baseline patient and tumor characteristics were tested for whether factors were associated with (1) all cause mortality and (2) cause-specific mortality. We also fit step-wise forward cause-specific-adjusted models. 7576 women (median age 64 years; 5417 (72 %) < 70 years and 2159 (28 %) ≥ 70 years) were enrolled and followed for median 4.1 years. The 432 deaths comprised 187 (43 %) BC, 66 (15 %) cardiovascular, and 179 (41 %) OT. Five baseline factors were differentially associated with type of death. Older patients had greater BC (p = 0.03), cardiovascular (p < 0.001), and other types (p < 0.001) of mortality. Patients with pre-existing cardiovascular history had worse cardiovascular mortality (p < 0.001); those with worse ECOG performance status had worse OT mortality (p < 0.001). Patients with T1 tumors (p < 0.001) and progesterone receptor positive had less BC mortality (p < 0.001). Fewer BC deaths occurred with node-negative disease (p < 0.001), estrogen receptor-positive tumors (p = 0.001), and without adjuvant chemotherapy (p = 0.005); worse cardiovascular mortality (p = 0.01), with trastuzumab; worse OT mortality, for non-whites (p = 0.03) and without adjuvant radiotherapy (p = 0.003). Overall, 57 % of deaths in MA.27 AI-treated patients were non-breast cancer related. Baseline patient and tumor characteristics differentially affected type of death with women 70 or older experiencing more non-breast cancer death.

Capecitabine 1000 mg/m(2) bid × 14 days every 21 days (14/21) has been reported to have similar efficacy but more favorable toxicity profile than the approved dosage of 1250 mg/m(2). However, a dose-toxicity relationship of capecitabine in breast cancer patients has not been fully elucidated. We performed a systematic review and meta-analysis to compare a safety profile between capecitabine starting dose of 1000 and 1250 mg/m(2) bid. Studies were identified using PubMed, ASCO, and San Antonio Breast Cancer Symposium abstract databases through December 2015. Eligible trials included phase II/III trials of capecitabine monotherapy at 1000 or 1250 mg/m(2) bid (14/21) for breast cancer patients that reported adequate safety data for all (grade 1-4) or high (grade 3-4) grade hand foot syndrome (HFS), diarrhea, fatigue, nausea, vomiting, stomatitis, neutropenia, thrombocytopenia, or anemia, as well as dose reductions, treatment discontinuation or treatment-related deaths. The summary incidence was calculated using random-effects models. A total of 4833 patients from 34 trials were included. 1218 and 3615 patients were treated with capecitabine 1000 and 1250 mg/m(2) bid, respectively. A significantly lower incidence of dose reduction (15.9 vs. 39.0 %; P = 0.007), high-grade HFS (12.0 vs. 19.0 %; P = 0.01), diarrhea (5.3 vs. 9.1 %; P = 0.01), and neutropenia (1.8 vs. 7.3 %; P

Statins have the potential to reduce breast cancer incidence and recurrence as shown in both epidemiologic and laboratory studies. The purpose of this study was to evaluate the effect of a lipophilic statin, atorvastatin, on breast cancer biomarkers of risk [mammographic density (MD) and insulin growth factor 1 (IGF-1)] in high-risk premenopausal women. Premenopausal women at increased risk for breast cancer received either 40 mg of atorvastatin or placebo for 1 year. Biomarker assessment was performed prior to initiation and at completion of study medication. MD was determined using both Breast Imaging Reporting and Data System and the visual analogue scale. Serum IGF-1 was determined by ELISA assay at the end of the study. Sixty-three women were enrolled between December 2005 and May 2010. Sixteen (25%) women withdrew. The mean age of participants was 43 (range, 35–50), 100% were white, and the average body mass index (BMI) was 26.4. The statin group demonstrated a significant decrease in cholesterol and low-density lipoprotein (LDL), suggesting compliance with study medication. After accounting for BMI, there was no difference in change in MD between groups. There was a significant increase in serum IGF-1 in the statin group. In this multi-institutional randomized prospective clinical trial of premenopausal women at increased risk for breast cancer, we did not see an effect of atorvastatin on MD. Further investigation of statins may be warranted; however, design of prior trials and potential mechanism of action of the agent need to be considered in the design of future trials.

Older women experience a large share of breast cancer incidence and death. With the projected rise in the number of older cancer patients, adjuvant chemo-, radiation and endocrine therapy management will become a key component of breast cancer treatment in older women. Many factors influence adjuvant treatment decisions including patient preferences, life expectancy and tumor biology. Geriatric assessment predicts important outcomes, identifies key deficits, and can aid in the decision making process. This review utilizes clinical vignettes to illustrate core principles in adjuvant management of breast cancer in older women and suggests an approach incorporating life expectancy and geriatric assessment.

BACKGROUND The number of survivors of breast cancer aged ≥65 years (“older”) is growing, but to the authors' knowledge, little is known regarding the cognitive outcomes of these individuals. METHODS A cohort of cognitively intact older survivors with nonmetastatic, invasive breast cancer was recruited from 78 sites from 2004 through 2011; approximately 83.7% of the survivors (1280 survivors) completed baseline assessments. Follow‐up data were collected at 6 months and annually for up to 7 years (median, 4.1 years). Cognitive function was self‐reported using the European Organization for Research and Treatment of Cancer Quality of Life Questionnaire Core 30 (EORTC QLQ‐C30); scores ranged from 0 to 100, with a higher score indicating better function. Group‐based trajectory modeling determined trajectories; women were assigned to a trajectory group based on the highest predicted probability of membership. Multinomial logistic regression evaluated the association between receipt of chemotherapy (with or without hormonal treatment) and trajectory group. RESULTS Survivors were aged 65 to 91 years; approximately 41% received chemotherapy. There were 3 cognitive trajectories: “maintained high” (42.3% of survivors); “phase shift” (50.1% of survivors), with scores slightly below but parallel to maintained high; and “accelerated decline” (7.6% of survivors), with the lowest baseline scores and greatest decline (from 71.7 [standard deviation, 19.8] to 58.3 [standard deviation, 21.9]). The adjusted odds of being in the accelerated decline group (vs the maintained high group) were 2.1 times higher (95% confidence interval, 1.3‐3.5) for survivors who received chemotherapy (with or without hormonal therapy) versus those treated with hormonal therapy alone. Greater comorbidity and frailty also were found to be associated with accelerated decline. CONCLUSIONS Trajectory group analysis demonstrated that the majority of older survivors maintained good long‐term self‐reported cognitive function, and that only a small subset who were exposed to chemotherapy manifested accelerated cognitive decline. Future research is needed to determine factors that place some older survivors at risk of experiencing cognitive decline. Cancer 2016;122:3555–3563. © 2016 American Cancer Society, Among older survivors of breast cancer who were followed for up to 7 years, approximately 42% reported maintaining high cognitive function, but receipt of chemotherapy (with or without hormonal therapy) appeared to double the odds of being in the group that reported accelerated cognitive decline (vs maintaining high function), compared with receiving hormonal treatment alone. Further research is needed to determine factors that place some older survivors at risk of experiencing cognitive decline.

Bendamustine in combination with rituximab (BR) has been associated with high response rates and acceptable toxicity in older patients with relapsed/refractory diffuse large B-cell lymphoma (DLBCL). Evaluation of BR is warranted in the front-line setting for DLBCL patients not eligible for anthracyclines or for the elderly. In this phase II study, we enrolled DLBCL patients aged ≥65 years who were poor candidates for R-CHOP (rituximab, cyclophosphamide, doxorubicin, vincristine, prednisone) to determine the efficacy and safety of BR in previously untreated stage II-IV DLBCL. Twenty-three patients were enrolled with a median age of 80 years. 52% of patients presented with poor functional status (Eastern Cooperative Oncology Group performance score of ≥2). The overall response rate was 78% with 12 complete responses (52%). At a median follow up of 29 months, the median overall survival was 10·2 months and the median progression-free survival was 5·4 months. The most common grade 3/4 adverse events were haematological. Combination therapy with BR demonstrates high response rates as front-line therapy in frail older patients with DLBCL, but survival rates were low. BR should be used with caution in future clinical trials involving older DLBCL patients with poor functional status.

Breast cancer is the most common cancer among women over the age of 65 years. The objectives of this chapter are to review the value of clinical assessment tools for older adults with breast cancer and to discuss breast cancer prevention, screening, and treatment specific for older adults. The geriatric assessment is an important tool that oncologists can use to better assess an older adult’s functional age and provides additional information beyond standard performance status measures. The geriatric assessment has been shown to uncover problems not detected in a routine oncologic evaluation and also aids in predicting treatment-related toxicity in older adults with solid tumors. Healthy older women with breast cancer should be managed like younger postmenopausal women, including breast conservation therapy if feasible and adjuvant systemic therapy. Frail older women and those with significant comorbidity frequently require treatment modifications. Older women with breast cancer should be routinely encouraged to participate in clinical trials to further develop evidence-based practices for the management and treatment of breast cancer in older adults.

Tumors are capable of shedding DNA into the blood stream. This shed DNA may be recovered from serum or plasma. The objective of this study was to evaluate whether pyrosequencing promoter DNA in a panel of 12 breast cancer-related genes (APC, BRCA1, CCND2, CDH1, ESR1, GSTP1, HIN1, P16, RARβ, RASSF1, SFRP1 and TWIST) to measure the degree of methylation would lead to a useful serum-based marker of breast cancer. Serum was obtained from women who were about to undergo a breast biopsy or mastectomy at three hospitals from 1977 to 1987 in Grand Rapids, MI USA. We compared the methylation status of 12 genes in serum DNA obtained from three groups of postmenopausal women (mean age at blood collection: 63.0 y; SD 9.9; range 35–91): breast cancer cases with lymph node-positive disease (n = 241); breast cancer cases with lymph node-negative disease (n = 63); and benign breast disease control subjects (n = 234). Overall, median levels of promoter methylation were low, typically below 5%, for all genes in all study groups. For all genes, median levels of methylation were higher (by 3.3 to 47.6%) in lymph node-positive breast cancer cases than in the controls. Comparing mean methylation level between lymph-node positive cases and controls, the most statistically significant findings, after adjustment of the false-positive rate (q-value), were for TWIST (p = 0.04), SFRP1 (p = 0.16), ESR1 (p = 0.17), P16 (p = 0.19) and APC (p = 0.19). For two of these four genes (TWIST, P16), the median methylation level was also highest in lymph-node positive cases, intermediate in lymph node-negative cases and lowest in the controls. The percent of study subjects with mean methylation scores ≥ 5% was higher among lymph node-positive cases than controls for ten genes, and significantly higher for HIN1 and TWIST (22.0 vs. 12.2%, p = 0.04 and 37.9 vs. 24.5%, p = 0.004, respectively). Despite relatively consistent variation in methylation patterns among groups, these modest differences did not provide sufficient ability to distinguish between cases and controls in a clinical setting.

Overview: Breast cancer is a disease of aging. However, older women with breast cancer are less likely to participate in clinical trials or to receive recommended treatment. This undertreatment has contributed to a lag in breast cancer survival outcomes for older women compared with that for their younger counterparts. The principles that govern recommendations for adjuvant treatment of breast cancer are the same for younger and older women. Systemic adjuvant treatment recommendations should be offered on the basis of tumor characteristics that divide patients into three distinct subgroups. These include (1) older women with hormone receptor (HR)-positive and human epidermal growth factor 2 (HER2)-negative breast cancer who should be offered endocrine therapy; (2) older women with HR-negative and HER2-negative breast cancer who should be offered adjuvant chemotherapy; and (3) older women with HER2-positive disease who should be offered chemotherapy with trastuzumab. Exceptions to these guidelines may be made for older women with small node-negative tumors or frail older women with limited life expectancy, where close surveillance may be a reasonable alternative. Addressing the current age-related disparities in breast cancer survival will require that older women are offered the same state-of-the-art-treatment as their younger counterparts, with a careful weighing of the risks and benefits of each treatment in the context of the individual's preferences. In addition, older women should be encouraged to participate in breast cancer clinical trials to generate additional chemotherapy efficacy, toxicity, and quality of life data.

In September 2010, the Cancer and Aging Research Group, in collaboration with the National Cancer Institute and the National Institute on Aging, conducted the first of three planned conferences to discuss research methodology to generate the highest quality research in older adults with cancer and then disseminate these findings among those working in the fields of cancer and aging. Conference speakers discussed the current level of research evidence in geriatric oncology, outlined the current knowledge gaps, and put forth principles for research designs and strategies that would address these gaps within the next 10 years. It was agreed that future oncology research trials that enroll older adults should include: (1) improved standardized geriatric assessment of older oncology patients, (2) substantially enhanced biological assessment of older oncology patients, (3) specific trials for the most vulnerable and/or those older than 75 years, and (4) research infrastructure that specifically targets older adults and substantially strengthened geriatrics and oncology research collaborations. This initial conference laid the foundation for the next two meetings, which will address the research designs and collaborations needed to enhance therapeutic and intervention trials in older adults with cancer.

Two Cancer and Leukemia Group B (CALGB) studies were utilized to determine the efficacy and tolerability of paclitaxel (Taxol) in older patients with metastatic breast cancer.CALGB 9840 evaluated weekly paclitaxel (80 mg/m(2)) versus paclitaxel every 3 weeks (175 mg/m(2)); CALGB 9342 evaluated three doses of paclitaxel as follows: 175, 210 and 250 mg/m(2) each over 3 h every 3 weeks. Of the 1048 patients, paclitaxel was used first line in 57%. The groups: (i)55 years (45%), (ii) 55-64 years (29%), and (iii) ≥65 years (26%).Tumor response was also similar among age groups. First-line therapy (P = 0.0001) and better performance status (PS) (P = 0.018) were significantly related to higher response. Age did not significantly relate to overall survival (OS) or progression-free survival (PFS). First-line therapy, better PS, estrogen receptor positive status and a fewer number of metastatic sites were significantly related to improved OS and PFS. The grade ≥3 toxic effects that increased linearly with age were leucopenia (P = 0.0099), granulocytopenia (P = 0.022), anorexia (P = 0.028), bilirubin elevation (P = 0.0035) and neurotoxicity (P0.0001). Patients over 65 years receiving second-line therapy had the shortest time to neurotoxicity.Older women with breast cancer derive similar efficacy from treatment with paclitaxel as younger women. Older women are at increased risk for specific toxic effects.

Statins have been shown in epidemiological and laboratory studies to have breast cancer risk reduction properties. We evaluated the effect of atorvastatin on breast mammographic density (MD) and other breast cancer biomarkers in a small randomized placebo controlled trial. Methods: Premenopausal women at increased risk for breast cancer (due to family history, BRCA positivity, prior biopsy history or history of chemoradiotherapy for Hodgkins disease) enrolled after signing informed consent and received either 40 mg of atorvastatin or placebo daily for 1 year. Biomarker assessment was performed prior to initiation and prior to completion of study medication. MD was determined using both Breast Imaging Reporting and Data System (BI-RADS) and the Visual Analogue Scale (VAS). Results: 63 women were enrolled between 7/05 - 8/10 in this multi-institutional trial. 44 have completed study medication and 3 remain on study. 25% have withdrawn; 17% of them for toxicity/side effects. Of those completing the study; mean age was 47 (range 35–50), 96% Caucasian, mean BMI 26.8. 66% had a strong family history (2% were BRCA+), 27.7% had ADH/LCIS. We present analysis of MD in the first 37 women completing study drug. The two treatment groups were well balance for age, BMI, risk factors and baseline density. Mean density by VAS was 31.6% at study entry and 32.4% at end of treatment. There was no different in change in density over time between atorvastatin and placebo using either BIRAD or VAS; controlling for BMI did not change results. Futility analysis demonstrates low probability of a significant difference between treatment groups and the study was closed. Conclusions: In this multi-institutional randomized prospective clinical trial of premenopausal women at increased risk for breast cancer we have failed to demonstrate a significant effect of atorvastatin on mammographic density. There are several possible reasons for this relating to: the study population, method of density determination and/or biomarker analyzed. While the primary aim of this study (MD) was not met we have shown that biomarker studies can be done in a multi-institutional setting. Further biomarker evaluation may prove informative.

Approximately 40,000 women die as a result of breast cancer each year and many more live with advanced disease. When breast cancer recurs, the goals of treatment often shift from one of cure to controlling the disease for as long as possible while palliating symptoms interfering with the patient's functional status and quality of life. This requires ongoing discussions with the patient and family about the goals of care. Many symptoms depend on the site of metastasis, with bone being the most frequent, and commonly occur with fatigue, depression, insomnia, and pain. The purpose of this paper is to identify and provide an overview of the management of the most common symptoms in patients with breast cancer metastases.

Purpose Factors captured in a geriatric assessment can predict morbidity and mortality in older adults, but are not routinely measured in cancer clinical trials. This study evaluated the implementation of a geriatric assessment tool in the cooperative group setting. Patients and Methods Patients age ≥ 65 with cancer, who enrolled on cooperative group cancer trials, were eligible to enroll on Cancer and Leukemia Group B (CALGB) 360401. They completed a geriatric assessment tool before initiation of protocol therapy, consisting of valid and reliable geriatric assessment measures which are primarily self-administered and require minimal resources and time by healthcare providers. The assessment measures functional status, comorbidity, cognitive function, psychological state, social support, and nutritional status. The protocol specified criteria for incorporation of the tool in future cooperative group trials was based on the time to completion and percent of patients who could complete their portion without assistance. Patient satisfaction with the tool was captured. Results Of the 93 patients who enrolled in this study, five (5%) met criteria for cognitive impairment and three did not complete the cognitive screen, leaving 85 assessable patients (median age, 72 years). The median time to complete the geriatric assessment tool was 22 minutes, 87% of patients (n = 74) completed their portion without assistance, 92% (n = 78) were satisfied with the questionnaire length, 95% (n = 81) reported no difficult questions, and 96% (n = 82) reported no upsetting questions. One hundred percent of health care professionals completed their portion. Conclusion This brief, primarily self-administered geriatric assessment tool met the protocol specified criteria for inclusion in future cooperative group clinical trials.

Background : Diffuse large B-cell lymphoma (DLBCL) and Burkitt lymphoma (BL) are aggressive lymphomas that evolve rapidly and are fatal if untreated. Most treatment-related toxicities occur during the initial phase of therapy, particularly in the elderly and in patients with a high disease burden. Prephase therapy is used as a preventive strategy prior to definitive multiagent chemotherapy to ameliorate the development of toxicity, such as febrile neutropenia, tumor lysis syndrome, deterioration in performance status, and death. While this approach is often implemented, there are few data supporting when to initiate a prephase regimen, or whether this approach will be effective. We present data from our experience at the University of North Carolina Cancer Hospital. Methods : We conducted a retrospective analysis of patients (pts) diagnosed with DLBCL and BL between January 2016 and December 2017. Pts were divided into 'prephase' (PP) and 'non-prephase' (NPP) groups. The PP group received either prednisone (P) alone at 60 mg/kg oral daily from day -6 to day -1, or in combination with vincristine (V) 1 mg intravenously on day -6 (VP regimen), cyclophosphamide 200 mg/m2 on day -6 (CP regimen), or all three drugs (CVP regimen). Multiagent chemotherapy was given at day 0. Both groups were evaluated until day 30. ECOG performance status (PS), grade 3-4 cytopenias, absolute neutrophil count (ANC) and platelet nadirs, time to ANC and platelet recovery, episodes of febrile neutropenia, hospitalization and emergency (ER) visits, and next cycle dose reduction or delay, were compared in both groups. Results : Ninety-two pts (DLBCL n=82, and BL n=10) were identified. Clinical characteristics are shown in Table 1. Twenty-two pts received PP therapy (vs. NPP n=70). Median age at diagnosis was 59 years and 61 years for PP and NPP group, respectively. Female predominance was observed in both groups (PP 59% and NPP 54%). Poor baseline ECOG PS was significantly different between the PP and NPP group (median score 2 vs. 0, p Conclusions : Prephase therapy significantly improved PS by day 14 of definitive multiagent chemotherapy at first cycle. The overall improvement in PS was primarily caused by improvements in 2 groups: pts older than 60 years, and pts 60 years or younger with poor PS (ECOG PS 2 or more). This is consistent with who we would expect to benefit the most from prephase therapy. Patients who received prephase therapy had a significant reduction in the length of their ANC nadir, although, interestingly, the rate of febrile neutropenia was low in both arms. The length of the platelet nadir was also significantly reduced in the PP group. Conversely, the depth of platelet nadir was significantly lower in the PP group, which may be a reflection of more aggressive disease in this group. The prephase group trended towards a reduction in the number of hospital admissions, ER visits, and next cycle dose reduction or delays, but these did not reach statistical significance. Based on these results, we will implement a provider reminder to consider prephase therapy when using multiagent chemotherapy in pts with aggressive lymphomas older than 60 years, or pts Disclosures Grover: Seattle Genetics: Consultancy.

Pretreatment preferences for adjuvant therapy were examined and compared with actual treatment received.Before definitive surgery, women with node-negative breast cancer were asked to indicate their preference for adjuvant therapy in response to 3 different clinical scenarios. The scenarios provided precise risk, benefit, and side effect information with low-, moderate-, or high-risk risk of death from breast cancer. Contingency table and Spearman rank correlation coefficients were used to examine associations. Kruskal-Wallis rank sum tests were used for group comparisons, with the Friedman rank sum test being used for correlated samples.A total of 75 women enrolled between February 2002 and April 2005; 24% were aged65 years. After definitive surgery, 21% of women had ductal carcinoma in situ, and 89% had receptor-positive disease. There was a significant correlation between risk of recurrence and aggressiveness of treatment preferred (P.001). After surgical staging, the high-risk group received more aggressive treatment compared with the low-risk group (P = .004). In the 51 women with invasive receptor-positive tumors, there was a significant difference (P = .002) in aggressiveness of treatment received based on risk of recurrence. Only 45% of the women received what they had preferred for the level of their risk before surgery. Women were more likely to receive a less aggressive therapy than they preferred initially (P = .0002).This study is among the first to correlate pretreatment preference for therapy with the actual therapy received. Less than half of women received their indicated preference before definitive surgery, with most women receiving less aggressive therapy. Future studies will need to examine this discrepancy.

Purpose Breast cancer chemotherapy decisions in patients ≥ 65 years old (older) are complex because of comorbidity, toxicity, and limited data on patient preference. We examined relationships between preferences and chemotherapy use. Methods Older women (n = 934) diagnosed with invasive (≥ 1 cm), nonmetastatic breast cancer from 2004 to 2008 were recruited from 53 cooperative group sites. Data were collected from patient interviews (87% complete), physician survey (93% complete), and charts. Logistic regression and multiple imputation methods were used to assess associations between chemotherapy and independent variables. Chemotherapy use was also evaluated according to the following two groups: indicated (estrogen receptor [ER] negative and/or node positive) and possibly indicated (ER positive and node negative). Results Mean patient age was 73 years (range, 65 to 100 years). Unadjusted chemotherapy rates were 69% in the indicated group and 16% in the possibly indicated group. Women who would choose chemotherapy for an increase in survival of ≤ 12 months had 3.9 times (95% CI, 2.4 to 6.3 times; P < .001) higher odds of receiving chemotherapy than women with lower preferences, controlling for covariates. Stronger preferences were seen when chemotherapy could be indicated (odds ratio [OR] = 7.7; 95% CI, 3.8 to 16; P < .001) than when treatment might be possibly indicated (OR = 1.9; 95% CI, 1.0 to 3.8; P = .06). Higher patient rating of provider communication was also related to chemotherapy use in the possibly indicated group (OR = 1.9 per 5-point increase in communication score; 95% CI, 1.4 to 2.8; P < .001) but not in the indicated group (P = .15). Conclusion Older women's preferences and communication with providers are important correlates of chemotherapy use, especially when benefits are more equivocal.
