RESUMO

PURPOSE: We previously described a combined risk score (CRS) that integrates a multiple-ancestry polygenic risk score (MA-PRS) with the Tyrer-Cuzick (TC) model to assess breast cancer (BC) risk. Here, we present a longitudinal validation of CRS in a real-world cohort. METHODS: This study included 130,058 patients referred for hereditary cancer genetic testing and negative for germline pathogenic variants in BC-associated genes. Data were obtained by linking genetic test results to medical claims (median follow-up 12.1 months). CRS calibration was evaluated by the ratio of observed to expected BCs. RESULTS: Three hundred forty BCs were observed over 148,349 patient-years. CRS was well-calibrated and demonstrated superior calibration compared with TC in high-risk deciles. MA-PRS alone had greater discriminatory accuracy than TC, and CRS had approximately 2-fold greater discriminatory accuracy than MA-PRS or TC. Among those classified as high risk by TC, 32.6% were low risk by CRS, and of those classified as low risk by TC, 4.3% were high risk by CRS. In cases where CRS and TC classifications disagreed, CRS was more accurate in predicting incident BC. CONCLUSION: CRS was well-calibrated and significantly improved BC risk stratification. Short-term follow-up suggests that clinical implementation of CRS should improve outcomes for patients of all ancestries through personalized risk-based screening and prevention.

RESUMO

BACKGROUND: Overweight men with prostate cancer are more likely to suffer from recurrence and death following prostatectomy compared with healthy weight men. This study tested the feasibility of delivering a comprehensive program to foster weight loss before and weight maintenance after surgery in overweight men with localized prostate cancer. METHODS: Twenty overweight men scheduled for prostatectomy elected either the intervention (n = 15) or the nonintervention (n = 5). Anthropometrics, biomarkers, diet quality, nutrition literacy, quality of life, and long-term follow-up were assessed in both groups. RESULTS: The intervention led to 5.55 kg of weight loss including 3.88 kg of fat loss from baseline to surgery (mean = 8.3 weeks). The intervention significantly increased fiber, protein, fruit, nut, and vegetable intake; and decreased trans fats intake during weight loss. The intervention significantly reduced insulin, C-peptide, systolic blood pressure, leptin:adiponectin ratio, and visceral adiposity compared to the nonintervention. Post-surgically, weight loss was maintained. Changes in lipid profiles, nutrition literacy, and follow-up were not statistically significant in either group. CONCLUSION: Significant weight loss (≥5%) is feasible with a coaching intervention in overweight men preparing for prostatectomy and is associated with favorable cardiometabolic effects. This study is registered under NCT02252484 (www.clinicaltrials.gov).

RESUMO

We examined factors associated with self-reported use of genetic testing among breast cancer survivors based on a 2015 cross-sectional survey at eight Midwestern sites. Genetic testing was reported in 39% of our 1235 study participants, with higher utilization among those aged <50 and with a triple-negative cancer. Bilateral mastectomy, having relatives with breast cancer, and younger age were associated with increased genetic testing use. Increasing income, in interaction with age, was associated with use of genetic testing among younger but not older patients. Rural residency emerged as a possible barrier for genetic testing among women with triple-negative cancer.

RESUMO

The American cancer survivor population is ever-growing, with necessary follow-up primarily accomplished in a high-touch fashion-adding to unsustainability and fragmentation of care. Given the complexities of the health care system processes needed to support survivorship, engineering approaches may best address performance deficits and facilitate the provision of patient-centered care. Such collaboration between health care and engineering is recommended for redesigning health care delivery systems. By using Systems Engineering Initiative for Patient Safety (SEIPS), a systems engineering model widely used to improve health care quality and delivery, the authors examine the work system to identify the barriers and facilitators to necessary care in the presence of a survivorship care plan and visit. Recommendations for future improvement include ensuring that care-planning processes are dynamic, clearly assigned, resilient, and integrated with electronic health record systems.

RESUMO

PURPOSE: The purpose of the study was to prospectively examine changes in subjective and objective cognitive functions and quality of life (QOL) for pre- and peri-menopausal women receiving chemotherapy for breast cancer and to explore potential predictors of cognitive changes. METHODS: Participants were assessed as follows: prior to chemotherapy (T1), after cycle 3 (T2), within 2-3 weeks of completing adjuvant chemotherapy (T3) (N = 20), and 8+ years later (T4; n = 18). Objective cognitive function was measured with the High Sensitivity Cognitive Screen (T1, T3, T4). Subjective measures for cognitive function, depressive symptoms, fatigue, and mental and physical QOL were assessed at all time points. Estradiol levels were measured at T1, T2, and T3. The Functional Assessment of Cancer Therapy-Cognition and the MD Anderson Cancer Symptom Inventory item for neuropathy were administered at T4. RESULTS: No significant changes in objective cognitive function were found. However, participants reported decreased cognitive function over the course of treatment accompanied by depressive symptoms and fatigue. Depression and fatigue returned to near-baseline levels at T4, but over half of the participants continued to report mild to moderate depression. Estradiol levels were not associated with cognitive function. Neuropathy and higher body mass index (BMI) were associated with persistent cognitive complaints at T4 (adjusted R 2 = 0.712, p = 0.001). Higher QOL was correlated with better subjective cognitive function (r = 0.705, p = 0.002) and lower body mass index (r = - 0.502, p = 0.017) at T4. CONCLUSIONS: Further investigation of BMI, neuropathy, and depressive symptoms as predictors of persistent cognitive dysfunction following chemotherapy for breast cancer is warranted.

RESUMO

PURPOSE: Aromatase inhibitor-associated musculoskeletal symptoms (AIMSS) frequently occur in women being treated for breast cancer. Prior studies suggest high prevalence of vitamin D deficiency in breast cancer patients with musculoskeletal (MS) pain. We conducted a randomized, placebo-controlled trial to determine if 30,000 IU vitamin D3 per week (VitD3) would prevent worsening of AIMSS in women starting adjuvant letrozole for breast cancer. METHODS: Women with stage I-III breast cancer starting adjuvant letrozole and 25(OH)D level ≤40 ng/ml were eligible. All subjects received standard daily supplement of 1200 mg calcium and 600 IU vitamin D3 and were randomized to 30,000 IU oral VitD3/week or placebo. Pain, disability, fatigue, quality of life, 25(OH)D levels, and hand grip strength were assessed at baseline, 12, and 24 weeks. The primary endpoint was incidence of an AIMSS event. RESULTS: Median age of the 160 subjects (80/arm) was 61. Median 25OHD (ng/ml) was 25 at baseline, 32 at 12 weeks, and 31 at 24 weeks in the placebo arm and 22, 53, and 57 in the VitD3 arm. There were no serious adverse events. At week 24, 51% of women assigned to placebo had a protocol defined AIMSS event (worsening of joint pain using a categorical pain intensity scale (CPIS), disability from joint pain using HAQ-II, or discontinuation of letrozole due to MS symptoms) vs. 37% of women assigned to VitD3 (p = 0.069). When the brief pain inventory (BPI) was used instead of CPIS, the difference was statistically significant: 56 vs. 39% (p = 0.024). CONCLUSIONS: Although 30,000 IU/week of oral vitamin D3 is safe and effective in achieving adequate vitamin D levels, it was not associated with a decrease in AIMSS events based on the primary endpoint. Post-hoc analysis using a different tool suggests potential benefit of vitamin D3 in reducing AIMSS.

RESUMO

With a 5 year survival rate of approximately 80%, there is an increasing number of childhood cancer survivors in the United States. Childhood cancer survivors are at an increased risk for physical and psychosocial health problems many years after treatment. Long-term follow-up care should include education, development of individualized follow up plans and screening for health problems in accordance with the Children's Oncology Group survivor guidelines. Due to survivor, provider and healthcare system related barriers, adult survivors of childhood cancer (ASCC) infrequently are receiving care in accordance to these guidelines. In this paper we describe the stepwise process and collaboration between a children's hospital and an adult academic medical center that was implemented to develop the Survivorship Transition Clinic and address the needs of ASCC in our region. In the clinic model that we designed ASCC follow-up with a primary care physician in the adult setting who is knowledgeable about late effects of childhood cancer treatment and are provided transition support and education by a transition nurse navigator.

RESUMO

NCCN guidelines recommend genetic testing for all triple-negative breast cancer (TNBC) patients aged ≤60 years. However, due to the lack of prospective information in unselected patients, these guidelines are not uniformly adopted by clinicians and insurance carriers. The aim of this study was to determine the prevalence of BRCA mutations and evaluate the utility of NCCN guidelines in unselected TNBC population. Stage I-IV TNBC patients were enrolled on a prospective registry at academic and community practices. All patients underwent BRCA1/2 testing. Significant family history (SFH) was defined >1 relative with breast cancer at age ≤50 or ≥1 relative with ovarian cancer. Mutation prevalence in the entire cohort and subgroups was calculated. 207 TNBC patients were enrolled between 2011 and 2013. Racial/ethnic distribution: Caucasian (80 %), African-American (14 %), Ashkenazi (1 %). Deleterious BRCA1/2 mutations were identified in 15.4 % (32/207) of patients (BRCA1:11.1 %, BRCA2:4.3 %). SFH reported by 36 % of patients. Mutation prevalence in patients with and without SFH was 31.6 and 6.1 %, respectively. When assessed by age at TNBC diagnosis, the mutation prevalences were 27.6 % (≤50 years), 11.4 % (51-60 years), and 4.9 % (≥61 years). Using SFH or age ≤50 as criteria, 25 and 34 % of mutations, respectively, were missed. Mutation prevalence in patients meeting NCCN guidelines was 18.3 % (32/175) and 0 % (0/32) in patients who did not meet guidelines (p = .0059). In this unselected academic and community population with negligible Ashkenazi representation, we observed an overall BRCA mutation prevalence rate of 15.4 %. BRCA testing based on NCCN guidelines identified all carriers supporting its routine application in clinical practice for TNBC.

RESUMO

OBJECTIVES: To gather feasibility and preliminary data comparing two virtual delivery methods for providing Emerging From the Haze™ (Haze) to cancer survivors compared to waitlist control (WLC). SAMPLE & SETTING: Eligible participants (N = 93) reported cancer-related cognitive impairment following chemotherapy for stage I-III solid tumors, Hodgkin lymphoma, or non-Hodgkin lymphoma. METHODS & VARIABLES: A three-arm randomized design was used to compare virtual live group presentation of Haze sessions, virtual prerecorded Haze group sessions, and WLC. Data were collected at baseline, week 10, and week 14. RESULTS: Feasibility was demonstrated. Significant cognitive function improvement at week 10 versus WLC was reported for the live group, and clinical improvement was reported for the prerecorded group. The prerecorded group reported significant improvement at week 14 versus WLC in physical activity, sleep, and health-related quality of life. IMPLICATIONS FOR NURSING: Additional pilot and feasibility evidence for cognitive rehabilitation interventions was demonstrated. Prerecorded Haze delivery shows potential for clinical effectiveness and scalability. Future multisite research is warranted.

RESUMO

We conducted a phase II feasibility study of a 6-month behavioral weight loss intervention in postmenopausal overweight and obese women at increased risk for breast cancer and the effects of weight loss on anthropomorphic, blood, and benign breast tissue biomarkers. 67 women were screened by random peri-areolar fine-needle aspiration, 27 were registered and 24 participated in the interventional phase. The 24 biomarker evaluable women had a median baseline BMI of 34.2 kg/m(2) and lost a median of 11 % of their initial weight. Significant tissue biomarker modulation after the 6-month intervention was noted for Ki-67 (if restricted to the 15 women with any Ki-67 at baseline, p = 0.041), adiponectin to leptin ratio (p = 0.003); and cyclin B1 (p = 0.001), phosphorylated retinoblastoma (p = 0.005), and ribosomal S6 (p = 0.004) proteins. Favorable modulation for serum markers was observed for sex hormone-binding globulin (p < 0.001), bioavailable estradiol (p < 0.001), bioavailable testosterone (p = 0.033), insulin (p = 0.018), adiponectin (p = 0.001), leptin (p < 0.001), the adiponectin to leptin ratio (p < 0.001), C-reactive protein (p = 0.002), and hepatocyte growth factor (p = 0.011). When subdivided by <10 or >10 % weight loss, change in percent total body and android (visceral) fat, physical activity, and the majority of the serum and tissue biomarkers were significantly modulated only for women with >10 % weight loss from baseline. Some factors such as serum PAI-1 and breast tissue pS2 (estrogen-inducible gene) mRNA were not significantly modulated overall but were when considering only those with >10 % weight loss. In conclusion, a median weight loss of 11 % over 6 months resulted in favorable modulation of a number of anthropomorphic, breast tissue and serum risk and mechanistic markers. Weight loss of 10 % or more should likely be the goal for breast cancer risk reduction studies in obese women.

RESUMO

OBJECTIVE: Conduct a needs assessment to explore the experiences, barriers, and needs of genetic counselors (GCs), who counsel and refer young and metastatic breast cancer (BC) patients to support services, in order to develop resources to address any noticeable gaps. METHODS: GCs providing care to BC patients were eligible to complete the survey. Support services were defined as resources to address patient-centered healthcare, emotional, and quality-of-life needs. RESULTS: Most participants (n = 117) reported familiarity with cancer prevention services (93%); fewer were familiar with services secondary to a BC diagnosis (e.g., fatigue=16% and sexual health=24%). The volume of GCs indicating familiarity with support services increased significantly as work experience increased for seven services. Many (>50%) never referred patients to most (9/12) support services, excluding cancer prevention, mental health, and financial issues. Open-ended responses highlighted that GCs considered referrals to be outside their scope of practice or that healthcare systems prevent GCs from making referrals. CONCLUSION: GCs may benefit from curated resources and materials, especially for support services secondary to a BC diagnosis, to better support their patients. PRACTICAL IMPLICATIONS: Collaboration of GCs with other health professionals through integrative care programs may decrease burdens to accessing support services.

RESUMO

Obese breast cancer survivors have increased risk of recurrence and death compared to their normal weight counterparts. Rural women have significantly higher obesity rates, thus weight control intervention may be a key strategy for prevention of breast cancer recurrence in this population. This one-arm treatment study examined the impact of a group-based weight control intervention delivered through conference call technology to obese breast cancer survivors living in remote rural locations. The intervention included a reduced calorie diet incorporating prepackaged entrees and shakes, physical activity gradually increased to 225 min/week of moderate intensity exercise, and weekly group phone sessions. Outcomes included anthropomorphic, diet, physical activity, serum biomarker, and quality of life changes. Ninety-one percent of participants (31 of 34) attended >75% of intervention sessions and completed post-treatment data collection visits. At 6 months, significant changes were observed for weight (-12.5 ± 5.8 kg, 13.9% of baseline weight), waist circumference (-9.4 ± 6.3 cm), daily energy intake (-349 ± 550 kcal/day), fruits, and vegetables (+3.7 ± 4.3 servings/day), percent kcal from fat (-12.6 ± 8.6%), physical activity (+1235 ± 832 kcal/week; all P values <0.001), as well as significant reductions in fasting insulin (16.7% reduction, P = 0.006), and leptin (37.1% reduction, P < 0.001). Significant improvements were also seen for quality of life domains including mood, body image, and sexuality. In conclusion, the intervention produced >10% weight loss as well as significant improvements across multiple endpoints. The group phone-based treatment delivery approach may help disseminate effective weight control intervention to hard-to-reach breast cancer survivors.

RESUMO

OBJECTIVE: Rural women are understudied in research on weight control among breast cancer survivors despite having higher obesity rates than their urban counterparts placing them at higher risk for recurrence. The purpose of this survey study was to describe weight status and methods used for weight control in rural breast cancer survivors and to examine psychosocial factors in this population associated with weight change since breast cancer diagnosis. METHODS: Women treated for breast cancer within the past 6 years at one of three rural Cancer Centers were mailed a survey with a cover letter from their oncology provider. RESULTS: Survey respondents (n=918, 83% response rate) were 96% White non-Hispanic, on average 3.2 years from treatment, and 11% reported metastatic disease. Among respondents without known metastatic disease, 68% were overweight or obese, 37% were obese, and 25% reported a weight gain exceeding 5 kg since diagnosis. Among the overweight/obese women, 61% were currently attempting weight loss, and the most common weight loss method was dieting on one's own without assistance. Psychosocial factors associated with weight gain since diagnosis included depression, fear of cancer recurrence, diminished physical strength, body image concerns, relationship changes, and financial stressors. CONCLUSIONS: The high response rate indicates a general interest in body weight issues among rural BrCa survivors, and the findings highlight the need for weight control programs in this population. Findings also indicate that factors related to poor adjustment to breast cancer are associated with weight gain among rural women.

RESUMO

Oncology nurses are essential in all phases of cancer care; however, their role in survivorship care is unclear. To better understand the self-reported knowledge and educational needs on topics of survivorship care and oncology nurses' learning preferences, an online survey was conducted. Respondents self-reported knowledge level for 31 care topics, identified areas of most interest, topics needed to assist patients and address patient questions, and reported participation in continuing education and preferred learning methods. Knowledge was rated highest for topics of fatigue, anxiety, and fear of recurrence and lowest for issues related to finance, employment, and insurance. Nurses were most interested in late and long-term physical effects of cancer or treatment, managing emotional issues, cancer screening and surveillance, and complementary and alternative therapies. Study findings suggest that online learning methods would be feasible and well accepted by nurses to meet continuing education needs related to cancer survivorship.

RESUMO

The inflammation-resolving and insulin-sensitizing properties of eicosapentaenoic (EPA) and docosahexaenoic (DHA) fatty acids have potential to augment effects of weight loss on breast cancer risk. In a feasibility study, 46 peri/postmenopausal women at increased risk for breast cancer with a body mass index (BMI) of 28 kg/m2 or greater were randomized to 3.25 g/day combined EPA and DHA (ω-3-FA) or placebo concomitantly with initiation of a weight-loss intervention. Forty-five women started the intervention. Study discontinuation for women randomized to ω-3-FA and initiating the weight-loss intervention was 9% at 6 months and thus satisfied our main endpoint, which was feasibility. Between baseline and 6 months significant change (P < 0.05) was observed in 12 of 25 serum metabolic markers associated with breast cancer risk for women randomized to ω-3-FA, but only four for those randomized to placebo. Weight loss (median of 10% for trial initiators and 12% for the 42 completing 6 months) had a significant impact on biomarker modulation. Median loss was similar for placebo (-11%) and ω-3-FA (-13%). No significant change between ω-3-FA and placebo was observed for individual biomarkers, likely due to sample size and effect of weight loss. Women randomized to ω-3-FA exhibiting more than 10% weight loss at 6 months showed greatest biomarker improvement including 6- and 12-month serum adiponectin, insulin, omentin, and C-reactive protein (CRP), and 12-month tissue adiponectin. Given the importance of a favorable adipokine profile in countering the prooncogenic effects of obesity, further evaluation of high-dose ω-3-FA during a weight-loss intervention in obese high-risk women should be considered. PREVENTION RELEVANCE: This study examines biomarkers of response that may be modulated by omega-3 fatty acids when combined with a weight-loss intervention. While focused on obese, postmenopausal women at high risk for development of breast cancer, the findings are applicable to other cancers studied in clinical prevention trials.

RESUMO

Aerobic exercise reduces risk for breast cancer and recurrence and promotes visceral adipose tissue (VAT) loss in obesity. However, few breast cancer survivors achieve recommended levels of moderate to vigorous physical activity (MVPA) without supervision. In a two-cohort study, feasibility of 12 weeks of partially supervised exercise was started concomitantly with caloric restriction and effects on body composition and systemic risk biomarkers were explored. In total, 22 obese postmenopausal sedentary women (including 18 breast cancer survivors) with median age of 60 and BMI of 37 kg/m2 were enrolled. Using personal trainers twice weekly at area YMCAs, MVPA was escalated to ≥200 min/week over 9 weeks. For cohort 2, maintenance of effect was assessed when study provided trainer services were stopped but monitoring, group counseling sessions, and access to the exercise facility were continued. Median post-escalation MVPA was 219 min/week with median 12-week mass and VAT loss of 8 and 19%. MVPA was associated with VAT loss which was associated with improved adiponectin:leptin ratio. In total, 9/11 of cohort-2 women continued the behavioral intervention for another 12 weeks without trainers. High MVPA continued with median 24-week mass and VAT loss of 12 and 29%. This intervention should be further studied in obese sedentary women.

RESUMO

Vitamin D deficiency and insufficiency may contribute to musculoskeletal symptoms and bone loss observed in women taking aromatase inhibitors (AIs). This study was conducted to determine the prevalence of suboptimal vitamin D levels in women initiating adjuvant letrozole for breast cancer and to determine whether supplementation with 50,000 IU of vitamin D3 weekly could reduce musculoskeletal symptoms and fatigue in women who have suboptimal vitamin D levels. Sixty women about to begin an adjuvant AI were enrolled. Baseline 25OHD levels were obtained, and women completed symptom questionnaires. They were then started on letrozole, along with standard dose calcium and vitamin D. Four weeks later, women with baseline 25OHD levels 40 ng/ml were achieved in all 42 subjects who received 12 weeks of supplementation with 50,000 IU vitamin D3 weekly, with no adverse effects. After 16 weeks of letrozole, more women with 25OHD levels >66 ng/ml (median level) reported no disability from joint pain than did women with levels <66 ng/ml (52 vs. 19%; P = 0.026). Vitamin D deficiency and insufficiency are prevalent in post-menopausal women initiating adjuvant AI. Vitamin D3 supplementation with 50,000 IU per week is safe, significantly increases 25OHD levels, and may reduce disability from AI-induced arthralgias.

RESUMO

PURPOSE: To create a community of learning involving primary care providers and subspecialist to enhance providers' knowledge regarding care of adult childhood cancer survivors (CCS). METHODS: A stepwise approach was used to develop educational opportunities for providers. This process started with a local/regional in-person conference, which informed a webinar series, and resulted in the development of enduring material using a dynamic learning management system. RESULTS: Participants in all three learning platforms had an increase in knowledge from baseline regarding care for adult CCS. Majority of participants at the in-person conference and webinar series were oncology or other specialty providers. The enduring dynamic learning management system successfully reached a variety of providers and other allied health providers across the country. There was a slightly higher rate of participation on this platform by primary care providers of 12.5%. CONCLUSIONS: Care providers' knowledge of survivorship needs of adult CCS can be increased by multiple forms of instruction. However, the dynamic learning management system was most successful at reaching a broad audience. Advertisement through local and national organizations was not as successful as anticipated. Additional strategies are needed to successfully engage providers, specifically primary care providers (PCPs). IMPLICATIONS FOR CANCER SURVIVORS: The professional development needs of primary care providers regarding care of adult CCS is well recognized. A dynamic learning management system may represent the most convenient and accessible way to provide education, but new strategies for increasing providers' awareness and engagement are required. The goal of improving care of adult CCS requires increased providers knowledge.
