Abstract P6-09-03: Improved clinical outcomes associated with statin use during adjuvant chemotherapy in patients with HER2+ non-metastatic breast cancer

Abstract Background Statins are established as first line therapy in patients with hypercholesterolemia and are thought to have pleiotropic effects including inhibition of signaling pathways known to drive cell proliferation and survival responses. Numerous preclinical and observational studies have demonstrated activity and improved outcomes in breast cancer patients who received statins, particularly lipophilic statins, as part of their adjuvant therapy. In the Life After Cancer Epidemiology (LACE) Study, 1,945 early-stage breast cancer survivors were shown to have a 33% decreased risk of breast cancer recurrence with post-diagnosis statin use, an effect that was magnified with increasing duration of statin use. We hypothesized that statin use concurrent with trastuzumab based chemotherapy in patients treated for non-metastatic HER2 positive breast cancer would be associated with improved outcomes. Methods We performed a retrospective review of all patients (n = 300) with HER2+ breast cancer who received trastuzumab from 2006-2012 at UM/SCCC. We identified two groups of patients for comparison - those who received statins (ST) during adjuvant chemotherapy (n = 45) or no statins during chemotherapy (NST) during adjuvant chemotherapy (n = 200). Patients with unclear documentation of concurrent statin use, men, patients with de-novo-metastatic breast cancer or prior primary cancer, bilateral breast cancers, and patients without follow-up were excluded. 5-year disease free (DFS) and overall survival (OS) were calculated. A univariate analysis was performed. Multivariate analysis for time-to-event data, using the Cox and extended Cox regression model will be performed and reported. Results The median age at diagnosis was 58 and 48, in the ST and NST groups, respectively. The most commonly used statin was lipophilic simvastatin (34.1%). The average baseline and post chemotherapy total cholesterol level in the ST group was 200.8 and 218.1mg/dL, respectively. Descriptive characteristics of the ST and NST groups respectively are as follows: postmenopausal (77.8% vs. 43.5%) tumor size <2cm (48.9% vs. 41.0%), node-negative disease (40.0% vs. 40.0%), HR+ status (64.4% vs. 60.5%), diabetes mellitus (26.7% vs. 9.0%), baseline BMI >30 (40.0% vs. 27.0%), and concomitant metformin (28.9% vs. 11.5%). The NST group was more likely to have a reduction of greater than 10% in their EF (9.0% vs. 6.7%). At a median follow-up of 32 and 26 months, the estimated 5-year DFS was significantly improved in the ST group (81.8% vs. 51.5%, p = 0.046). Meanwhile, the estimated 5-year OS was not significantly different between both groups (93.4% vs. 91.6%, p = 0.121). Metformin was not associated with a significant improvement in DFS or OS. Conclusion Our study demonstrated that statin use concurrent with trastuzumab-based chemotherapy for non-metastatic HER2 breast cancer was associated with improved estimated 5-year DFS, but not OS. The retrospective nature of our study does not allow for a definitive answer but further research needs to be done to define the role of statins in HER2+ breast cancer treatment.

Dietary changes and food intake in the first year after breast cancer treatment.

Understanding dietary habits of women after breast cancer is a critical first step in developing nutrition guidelines that will support weight management and optimal health in survivorship; however, limited data are available. The objective of this study was to describe changes in diet among breast cancer survivors in the first year after treatment, and to evaluate these changes in the context of current dietary intake. Changes in diet were assessed in 28 early stage breast cancer survivors, using a self-reported survey in which women identified changes in food intake since their diagnosis. Current dietary intake was estimated from 3-day food records and described relative to current recommendations. The majority of women reported changes in diet after diagnosis, most common being an increase in vegetables/fruit and fish, lower intake of red meat, and reduced alcohol. Many women reported that these changes were initiated during active treatment. Dietary changes were largely consistent with current recommendations for cancer prevention; however, some women were still above the guidelines for total and saturated fat, and many were below recommendations for vegetables/fruit, milk/alternatives, calcium, and vitamin D. Evidence that some women are willing and able to initiate positive changes in diet early in the treatment trajectory suggests that early intervention may be effective in promoting dietary habits that will assist with weight management and overall health. Data on current dietary intake highlights several possible targets for dietary intervention in this population.

Bridging to survivorship in breast cancer: Learning how treatment impacts mental health among early-stage breast cancer survivors.

33 Background: Depression (D) and anxiety (A) complicate survivorship in breast cancer (BC) patients (pts). The prevalence of D and A after BC treatment (Tx) in the community and concordance with BC Tx type is poorly described, but vitally important to characterize risks of Tx and optimize support for BC pts and goals for survivorship care planning. Methods: We queried the electronic health record (EHR), iKnowMed, from a a large network of community oncology practices for pts treated with stage I-III breast cancer from 2007-2010 with at least 5 visits and follow up through 2012 for our retrospective study. We excluded pts who developed metastatic disease or died. We stratified pts by chemotherapy (CT) utilization (yes/no),hormone receptor (HR) status, age, and documented body mass index (BMI) at diagnosis, and post diagnosis development of D (y/n), A (y/n) or utilization of venlafaxine (E) like antidepressants (Ads), non-E like Ads or anti-A medications within the study period. Time to onset of A or D was analyzed using Cox proportional hazard methodology. Results: We identified 8,506 patients with a documented BMI at 1, 2, and 3 years (yrs) post diagnosis. 4,369 (51%) of patients received adjuvant CT and 4,137 (49%) did not. Baseline characteristics were similar between tx groups, and active D or A was low at the time of dx, but as a whole rose to 41% during the study period. Pts with pre-existing D or A at the time of diagnosis were excluded. CT increases the risk of D or A (HR: 1.23, CI: 1.15-1.33). HR+ status also increases the risk of D or A (HR: 1.21, CI:1.11-1.32). Age conveyed a small diminished risk of D or A (HR: 0.98, CI: 0.98-0.99) while baseline BMI conveyed a small increased risk (HR: 1.02, CI 1.01-1.3). When excluding E like compounds that are often used to treat hot flashes in BC pts, CT was still found to have an increased risk of D or A (HR: 1.28, CI: 1.18-1.39), and HR+ was still associated with higher risk of D or A as well (HR: 1.11, CI: 1.01-1.22). Conclusions: Mental health disorders such as D and A are common among BC survivors, and more prevalent among BC survivors who received CT and have HR+ disease. This warrants further investigation on how to evaluate and support the mental health needs of BC survivors.

Posttraumatic growth and psychological distress in Chinese early‐stage breast cancer survivors: a longitudinal study

To describe the dynamic changes in posttraumatic growth (PTG) and psychological distress in hospitalized early-stage breast cancer (BC) survivors over a 6-month period. A longitudinal study design was adopted. The PTG inventory (PTGI) and distress management screening measure were used 3 months after diagnosis, then again at 6 and 9 months after diagnosis. For baseline data, 155 BC patients who were receiving chemotherapy were selected from four first-class tertiary hospitals in Beijing from April 2010 to March 2011 using a purposive sampling method. Of these, 120 BC patients completed the follow-up investigation. A repeated measures analysis of variance, followed by least significant difference post-hoc analysis, was used to compare PTG and psychological distress. The total score of the PTGI was 62.72 ± 14.66 in BC survivors at 3 months after diagnosis.There was a weak negative relationship between PTG and psychological distress (r = –0.282, p<0.001).PTG increased and psychological distress decreased from 3 to 9 months after diagnosis. The PTGI scores were 63.24 ± 14.21, 68.26 ± 15.29, and 70.29 ± 16.07 at 3, 6, and 9 months after diagnosis, respectively, with distress thermometer scores of 3.62 ± 1.98, 2.59 ± 2.00, and 2.51 ± 1.00, respectively. At 3 months after diagnosis, BC survivors develop PTG at a low level while they are receiving chemotherapy. PTG showed a weak negative association with psychological distress. The level of PTG shows an increasing tendency, whereas the degree of psychological distress exhibits a downward trend in the 9 months after diagnosis.

Use of imaging and biomarker tests for posttreatment care of early‐stage breast cancer survivors

The American Society of Clinical Oncology (ASCO) recently released a "Top Five" list of opportunities to improve the quality of cancer care. Item 4 on the list advises against using advanced imaging and biomarkers for surveillance in patients with breast cancer who are treated with curative intent. This study examined concordance with ASCO follow-up care guidelines for breast cancer survivors treated at an academic medical center. Claims data and medical records were reviewed and abstracted for early stage breast cancer survivors starting 1 year post diagnosis. A trained abstractor classified imaging tests as diagnostic or surveillance. Proportions and frequencies were generated for receipt of services. Multilevel logistic regression was used to estimate factors associated with receiving recommended and nonrecommended services and biomarker tests. Records were available for 258 patients. Mean age at diagnosis was 58 years (standard deviation of 13 years), mean time since diagnosis was 6 years (standard deviation of 2 years), and 71% were stage 0/1. Only 47% of the sample received a mammogram within 1 year of diagnosis, and 55% of the sample received at least 1 nonrecommended imaging service for surveillance purposes. Seventy-seven percent of the sample received at least 1 nonrecommended biomarker test. Regression results indicate that main treating physician, advanced disease stage, younger age at diagnosis, and greater number of years since diagnosis were associated with receiving nonrecommended services for surveillance. Use of nonrecommended services for surveillance occurs frequently among early-stage breast cancer survivors. There are opportunities to increase use of guideline concordant posttreatment care for breast cancer survivors.

The impact of endocrine therapy on sexual dysfunction in postmenopausal women with early stage breast cancer: encouraging results from a prospective study

The goal of this project was to investigate the contentious issue of a possible effect of endocrine therapy (ET) on sexual dysfunction (SD) in postmenopausal early stage breast cancer survivors. To date, few studies have assessed sexual functioning prior to initiating ET and none have taken sexual distress into account when reporting the prevalence of ET-induced SD. We report the findings of a study on the change in SD (defined as experiencing sexual problems causing distress) during the first 6 months of ET usage. Between January 2009 and May 2011, 118 patients entered the study and 66 completed questionnaires prior to initiation of ET and after 6 months of use. Sexual functioning (SF) was evaluated with the female sexual function index while sexual distress was assessed with the female sexual distress scale (FSDS-R). Gynecological symptoms were measured with the FACT-B ES subscale. Over time, the level of gynecological symptoms increased (p < 0.001), whereas no decline in SF was observed. The percentage of women who reported experiencing at least one sexual problem (85 %) and the percentage who were sexually distressed (30 %) remained the same across time. Importantly, the change in the prevalence of SD between baseline (24 %) and 6 months (29 %) was not statistically significant. Women experiencing SD at baseline were more likely to experience SD after 6 months of ET usage (OR = 7.4, 95 % CI = 1.5-36.9) than women who had no SD prior to initiating ET. The observation that SF remained stable across time is encouraging news. However, longer follow-up and the inclusion of women who were premenopausal at diagnosis are needed to determine the potential influence of extended duration of ET (e.g., at least 5 years) on SD. Further studies, including assessing the impact of early identification of patients at risk of developing SD and timely intervention, are warranted.

The effect of psychosocial interventions delivered by telephone and videophone on quality of life in early-stage breast cancer survivors and their supportive partners

Summary We examined the effectiveness of two psychosocial interventions for improving QOL in recently diagnosed breast cancer survivors and their partners. The interventions were telephone health education (THE) and interpersonal counselling. The latter was delivered by telephone (TC) or by videophone (VC) in 8 weekly one-to-one sessions. Fifty two dyads composed of a woman with breast cancer and her supportive partner were randomly assigned to THE, TC or VC. The average age of the survivors was 53 years (range 40–66), and they were mainly white, married, with a college education, and employed. Approximately half of the supportive partners were spouses. Surveys of quality of life (QOL) were made at three points in the study, each separated by 8 weeks. There was significantly higher attrition in the THE group compared to the videophone or telephone counselling groups among both survivors (44% vs. 10% and 8%) and partners (44% vs. 10% and 15%). Regardless of group, participants showed increased QOL over time. Survivors’ and partners’ social well-being improved in the telephone and videophone interpersonal counselling treatment groups, but not in the health education group. Telephone-delivered psychosocial interventions can be effective for managing QOL in breast cancer survivors and their supportive partners. There was no evidence of superior outcomes associated with using videophones over the conventional telephone.

Mortality risk in former smokers with breast cancer: Pack‐years vs. smoking status

It is unclear why successful quitting at time of breast cancer diagnosis should remove risk from a significant lifetime of smoking. Studies concluding this may be biased by how smoking is measured in many epidemiological cohorts. In the late 1990s, a randomized trial of diet and breast cancer outcomes enrolled early-stage female breast cancer survivors diagnosed within the previous 4 years. Smoking history and key covariate measures were available at study entry for 2,953 participants. Participants were followed for an average of 7.3 years (96% response rate). There were 10.1% deaths (83% from breast cancer). At enrollment, 55.2% were never smokers, 41.2% former smokers and 4.6% current smokers. Using current smoking status in a Cox regression, there was no increased risk for former smokers for either all-cause mortality [hazard ratio (HR) = 1.11; 95% confidence interval (CI) = 0.87-1.41; p-value = 0.42) or breast cancer mortality. However, when we categorized on extensive lifetime exposure, former smokers with 20+ pack-years of smoking (25.8%) had a significantly higher risk of both all-cause (HR = 1.77; 95% CI = 1.17-2.48; p-value = 0.0007) and breast cancer-specific mortality (HR = 1.62; 95% CI = 1.11-2.37; p-value = 0.01). Lifetime smoking exposure, not current status, should be used to assess mortality risk among former smokers.

Periodontal health in early-stage postmenopausal breast cancer survivors on aromatase inhibitors.

568 Background: Aromatase inhibitors (AIs) are associated with profound estrogen deprivation resulting in reduced bone mineral density (BMD). Periodontal diseases and tooth loss are associated with estrogen withdrawal and decreased systemic BMD. Little is known as to the impact of AIs on oral health. To investigate oral health as a breast cancer (BCA) survivorship concern, a prospective study was initiated to determine the prevalence of periodontal diseases in postmenopausal early stage (I-IIIA) BCA survivors on adjuvant AI therapy. Baseline assessments are presented here. Methods: Women within 6 months of initiating adjuvant AI for hormone receptor positive BCA were eligible to participate in this study of serial assessments of oral health. A control group of women without BCA and not on AI underwent parallel assessments. Periodontal status was evaluated by the following established dental techniques; (1) periodontal pocket depth (PD), (2) number of teeth with bleeding on probing (BOP), (3) the number of teeth with clinical attachment loss (CAL). Questionnaires regarding socio-demographic and dental utilization were administered to all participants. Linear regression modeling was used to analyze the outcomes. Results: The study met its target accrual of 58 postmenopausal women; 29 with BCA on AI and 29 controls. Demographics were similar regarding age, education, income level, frequency of dental visits, and dental insurance status across both groups. Baseline assessments demonstrated no differences in PD (2.0 mm vs. 2.0 mm; p &lt; 0.95) or the number of teeth (26.6 vs 26.1; p&lt; 0.39). Interestingly, the AI group had significantly more sites of BOP (27.9 vs 16.7; p &lt; 0.02), and higher CAL (5.2 mm vs 4.0 mm; p &lt; 0.01) than did controls. In linear regression analysis adjusted for income, AI use increased CAL by 1 mm (95% CI: 0.15 -1.88). There was also a trend for decreased CAL in subjects with incomes over $75,000 per year (p&lt; 0.06). Conclusions: This first investigation of the periodontal status of women initiating adjuvant AI therpay identifies this population to have signs of increased risk for periodontal disease. Serial oral health assessments are being conducted to assess AI therapy and periodontal changes over time. Clinical trial information: NCT01693731.

Bridging to survivorship in breast cancer: Learning how treatment impacts mental health among early-stage breast cancer survivors.

9604 Background: Depression (D) and anxiety (A) complicate survivorship in breast cancer (BC) patients (pts). The prevalence of D and A after BC treatment (Tx) in the community and concordance with BC Tx type is poorly described, but vitally important to characterize risks of Tx and optimize support for BC pts and goals for survivorship care planning. Methods: We queried the electronic health record (EHR), iKnowMed, from a a large network of community oncology practices for pts treated with stage I-III breast cancer from 2007-2010 with at least 5 visits and follow up through 2012 for our retrospective study. We excluded pts who developed metastatic disease or died. We stratified pts by chemotherapy (CT) utilization (yes/no),hormone receptor (HR) status, age, and documented body mass index (BMI) at diagnosis, and post diagnosis development of D (y/n), A (y/n) or utilization of venlafaxine (E) like antidepressants (Ads), non-E like Ads or anti-A medications within the study period. Time to onset of A or D was analyzed using Cox proportional hazard methodology. Results: We identified 8,506 patients with a documented BMI at 1, 2, and 3 years (yrs) post diagnosis. 4369(51%) of patients received adjuvant CT and 4137 (49%) did not. Baseline characteristics were similar between tx groups, and active D or A was low at the time of dx, but as a whole rose to 41% during the study period. Pts with pre-existing D or A at the time of diagnosis were excluded. CT increases the risk of D or A (HR: 1.23, CI: 1.15-1.33). HR+ status also increases the risk of D or A (HR: 1.21, CI:1.11-1.32). Age conveyed a small diminished risk of D or A (HR: 0.98, CI: 0.98-0.99) while baseline BMI conveyed a small increased risk (HR: 1.02, CI 1.01-1.3). When excluding E like compounds that are often used to treat hot flashes in BC pts, CT was still found to have an increased risk of D or A (HR: 1.28, CI: 1.18-1.39), and HR+ was still associated with higher risk of D or A as well (HR: 1.11, CI: 1.01-1.22). Conclusions: Mental health disorders such as D and A are common among BC survivors, and more prevalent among BC survivors who received CT and have HR+ disease. This warrants further investigation on how to evaluate and support the mental health needs of BC survivors.

Fracture Risk in Older, Long‐Term Survivors of Early‐Stage Breast Cancer

To examine the effect of breast cancer and its treatment on fracture risk in older breast cancer survivors. A 10-year prospective cohort study beginning 5 years after a diagnosis of breast cancer for survivors and match date for comparison women. Six integrated healthcare systems. Women aged 65 and older (1,286 survivors, 1,286 comparison women, mean age 77.7 in both groups, white, non-Hispanic: survivors, 81.6%; comparison women, 85.2%) who were alive and recurrence free 5 years after a diagnosis of early-stage breast cancer and matched on age, study site, and enrollment year to a comparison cohort without breast cancer. Cox proportional hazards models were used to estimate the association between fracture risk and survivor-comparison status, adjusting for drugs and risk factors associated with bone health. A subanalysis was used to evaluate the association between tamoxifen exposure and fracture risk. No difference was observed in fracture rates between groups (hazard ratio (HR) = 1.1, 95% confidence interval (CI) = 0.9-1.3). The protective effect of tamoxifen was not statistically significant (HR = 0.9, 95% CI = 0.6-1.2). Long-term survivors of early-stage breast cancer diagnosed at age 65 and older are not at greater risk of osteoporotic fractures than age-matched women without breast cancer. There appears to be no long-term protection from fractures with tamoxifen use.

Conquer fear: protocol of a randomised controlled trial of a psychological intervention to reduce fear of cancer recurrence.

BackgroundUp to 70% of cancer survivors report clinically significant levels of fear of cancer recurrence (FCR). Despite the known negative impact of FCR on psychological wellbeing and quality of life, little research has investigated interventions for high FCR. Our team has developed and piloted a novel intervention (Conquer Fear) based on the Self-Regulatory Executive Function Model and Relational Frame Theory and is evaluating Conquer Fear in a randomised controlled trial (RCT). We aim to compare the efficacy and cost-efficacy of the Conquer Fear Intervention and relaxation training in reducing the impact of FCR.Methods/designThis study is a multi-centre RCT with 260 participants randomised either to the Conquer Fear Intervention or relaxation training. Both interventions will be delivered in five sessions over 10 weeks by trained psychologists, psychiatrists and social workers with five or more years experience in oncology. Conquer Fear sessions use attentional training, detached mindfulness, meta-cognitive therapy, values clarification and psycho-education to help patients change the way they regulate and respond to thoughts about cancer recurrence. Relaxation training includes training in progressive and passive muscle relaxation, meditative relaxation, visualisation and “quick relaxation” techniques. Relaxation was chosen to control for therapist time and attention and has good face-validity as an intervention. The primary outcome is fear of cancer recurrence. Secondary outcomes include distress, quality of life, unmet needs, and health care utilisation. Participants complete questionnaires prior to starting the intervention, immediately after completing the intervention, 3 and 6 months later. Eligible participants are early-stage breast or colorectal cancer survivors who have completed hospital-based treatment between 2 months and 5 years prior to study entry and report a score in the clinical range on the Fear of Cancer Recurrence Inventory. The biostatistician is blinded to group allocation and participants are blinded to which intervention is being evaluated. Randomisation is computer generated, stratified by therapist, and uses sequentially numbered sealed envelopes.DiscussionIf successful, the study will provide an evidence-based intervention to reduce psychological morbidity in cancer survivors, and reduce overall health care costs due to more appropriate use of follow-up care and other health services in this very large population.Trial registrationTrial registration: ACTRN12612000404820

Engaging in Health Behaviors to Lower Risk for Breast Cancer Recurrence

PurposeWhile post-treatment breast cancer survivors face up to twice the cancer risk of the general population, modifiable health behaviors may somewhat reduce this risk. We sought to better understand health behaviors that early stage breast cancer survivors engage in to reduce recurrence risk.MethodsData came from a cross-sectional multi-site survey of 186 early-stage breast cancer survivors who received genomic testing for breast cancer recurrence risk (Oncotype DX) during their clinical care. Study outcomes were meeting health behavior recommendations (daily fruit and vegetable intake, regular physical activity, and having a healthy body mass index (BMI)).ResultsApproximately three-quarters of survivors we surveyed believed the 3 behaviors might reduce their cancer risk but many did not engage in these behaviors for this purpose: 62% for BMI, 36% for fruit and vegetable consumption, and 37% for physical activity. Survivors with higher recurrence risk, as indicated by their genomic test results, were no more likely to meet any of the three health behavior recommendations. Adherence to health behavior recommendations was higher for women who were white, college-educated, and had higher incomes.ConclusionsMany nonadherent breast cancer survivors wish to use these behavioral strategies to reduce their risk for recurrence, suggesting an important opportunity for intervention. Improving BMI, which has the largest association with cancer risk, is an especially promising target.

Abstract P4-01-09: Screening breast magnetic resonance imaging (MRI) in early-stage breast cancer survivors

Abstract Background: Limited evidence is available regarding the value of screening breast MRI in female early stage breast cancer survivors. We sought to evaluate outcomes of index screening breast MRI in breast cancer survivors in the modern era of breast cancer treatment and imaging. Methods: Using a large prospective institutional database, we identified all women who underwent breast MRI between 7/2006 and 6/2008, were ≥ 1 year and ≤ 3 years after diagnosis of stage I-IIIa breast cancer, had remaining breast tissue after treatment, and had consented to a record review protocol at our center (95% uptake rate). Sociodemographic, disease, staging and treatment information (see table 1), indications and outcomes for breast MRI, as well as disease status at 2 years after the index MRI were ascertained. Results: 643 patients were identified as having undergone at least 1 MRI of the breast(s); 248 (38.5%) were diagnostic MRIs (had identified clinical indication or imaging abnormality); 12 (2%) were missing clinical data; 383 (59.5%) were screening MRIs. 338/383 (88%) patients who had screening MRI had stage I-IIIa invasive breast cancer. 220/338 (65%) MRIs performed were index MRIs (index MRI defined as first MRI &amp;gt;1 year post diagnosis). For this preliminary analysis, we include only the 155 patients (70%) who were within 1–3 years of diagnosis at the time of index MRI (see table 1 for patient and disease characteristics). 24/155 (15.5%) screening MRIs were considered not normal. Five women (21%) underwent biopsy based on abnormal MRI finding; 1 resulted in the detection of a local recurrence (4.2%, 95% CI=0.1%–21.1%). 3/131 patients who had a normal index MRI were found to have local/regional recurrence or contralateral breast cancer diagnosed within 2 years of the MRI (2.3%, 95% CI=0.5%–6.6%). A statistically significant difference in the proportions was not observed based on Fisher's test (p = 0.50). 6/155 patients (3.9 %) had a systemic recurrence in the 2 years following index MRI. Conclusion: The vast majority of first screening breast MRIs obtained 1–3 years following treatment in early stage breast cancer survivors are normal, and very few detect cancer. Planned further analysis in this dataset will evaluate frequency of cancer detection in longer-term survivors. Additional research is necessary to determine the risks and benefits of screening breast MRIs being performed in this population.

An online stress management workbook for breast cancer

Cognitive behavioral stress management groups have been shown to be decrease psychological symptoms and increase adaptive coping in breast cancer patients, but dissemination of this effective intervention has been challenging. The goal of the present project was to develop an online cognitive behavioral stress management intervention for early stage breast cancer survivors and evaluate its effectiveness using a 2 group×3 time randomized, waitlist-controlled design. Intervention and waitlist control group participants were assessed at three time points: at baseline; at 10weeks, after which only intervention participants had used the workbook; and at 20weeks, after which both groups had used the workbook. Results indicate that at 10weeks intervention participants showed improved self-efficacy for coping with their cancer and for regulating negative mood and lower levels of cancer-related post-traumatic symptoms as compared to the control group, suggesting that an internet stress management intervention could be effective for helping breast cancer patients increase their confidence in their ability to cope with stress.

Use of advanced imaging and biomarker tests for post-treatment surveillance in early-stage breast cancer survivors.

168 Background: The American Society of Clinical Oncology (ASCO) released a “Top Five” list of opportunities to improve the quality of cancer care. #4 focused on post-treatment surveillance in breast cancer patients treated with curative intent. The ASCO guideline on breast cancer follow up advises against using advanced imaging and biomarkers in this setting. We undertook an examination of the patterns of follow-up care for breast cancer survivors treated at an academic medical center to evaluate use of non-recommended services. Methods: Claims data and medical records were reviewed and abstracted for early stage (0-IIIA) breast cancer survivors starting one year post diagnosis, with an average of 5 years of follow-up data. A trained abstractor classified imaging tests as diagnostic/surveillance based on medical record content. A 10% random sample was abstracted by a second abstractor and compared for concordance. Descriptive statistics were generated for patient demographic and medical characteristics, and proportions for receipt of non-recommended services, including if imaging procedures were performed for diagnostic/surveillance purposes. Multivariate logistic regression modeling was used to determine factors associated with receiving non-recommended services. Results: Records were available for 258 patients. The mean age was 62 (SD 13), mean time since diagnosis was 6 years (SD 2), 66% were stage 0/1. 35% received at least one abdominal CT, 31% at least one chest CT, 20% at least one PET, 30% at least one bone scan. Of these services, 90 abdominal CT scans (47%), 131 chest CT scans (65%), 77 PET scans (90%), and 29 bone scans (26%) were classified as surveillance. 80% received CEA and/or CA 27.29 tests; 8% received CA 15-3 tests. Logistic regression revealed no consistent association of medical, demographic, or provider factors with receiving non-recommended services. Conclusions: Use of non-recommended services for surveillance occurs frequently among early stage survivors. Providers in this academic center had no personal financial incentive for ordering these services. There are opportunities to increase use of guideline concordant post-treatment care for breast cancer survivors.

Worry About Cancer Progression and Low Perceived Social Support: Implications for Quality of Life Among Early-Stage Breast Cancer Patients

Worry about cancer progression and perceived social support can affect cancer survivors' quality of life (QOL). In 480 early-stage breast cancer survivors, we examined how worry about cancer progression and perceived social support 6 months after definitive surgery were associated with QOL (RAND 36-item Health Survey) at 6-, 12-, and 24-month follow-up. At 6 months post-surgery, higher worry was associated with worse QOL for five of eight subscales. Lower social support was associated with worse QOL for four subscales. The negative effects of worry and limited social support dissipated for four subscales (worry) and two subscales (social support) by 12-month follow-up and for all subscales by 24-month follow-up. Social support at 6 months moderated the relationship between T2 worry and T4 emotional well-being; post hoc tests did not clarify the nature of the interaction. Early-stage breast cancer survivors who worry about cancer progression and/or have low social support may experience lower levels of QOL that can take several months to resolve.

Adult Cancer Survivors Discuss Follow-up in Primary Care: 'Not What I Want, But Maybe What I Need'

BACKGROUND Nearly one-third of office visits for cancer are handled by primary care physicians. Yet, few studies examine patient perspectives on these physicians' roles in their cancer follow-up care or their care preferences. METHODS We explored survivor preferences through qualitative, semistructured, in-depth interviews drawing on patients recruited from 2 National Cancer Institute-designated comprehensive cancer centers and 6 community hospitals. We recruited a purposive sample of early-stage breast and prostate cancer survivors aged 47 to 80 years, stratified by age, race, and length of time from and location of cancer treatment. Survivors were at least 2 years beyond completion of their active cancer treatment RESULTS Forty-two survivors participated in the study. Most participants expressed strong preferences to receive follow-up care from their cancer specialists (52%). They described the following barriers to the primary care physician's engagement in follow-up care: (1) lack of cancer expertise, (2) limited or no involvement with original cancer care, and (3) lack of care continuity. Only one-third of participants (38%) believed there was a role for primary care in cancer follow-up care and suggested the following opportunities: (1) performing routine cancer-screening tests, (2) supplementing cancer and cancer-related specialist care, and (3) providing follow-up medical care when "enough time has passed" or the survivors felt that they could reintegrate into the noncancer population. CONCLUSION Survivors have concerns about seeing their primary care physician for cancer-related follow-up care. Research interventions to address these issues are necessary to enhance the quality of care received by cancer survivors.

Understanding how breast cancer patients use risk information from genomic tests

We sought to examine how patients' treatment decisions incorporate potentially conflicting information from standard clinical indicators (e.g., tumor size) and genomic tests for breast cancer recurrence risk. Participants were 77 early stage breast cancer survivors who previously received genomic testing. They read six hypothetical vignettes that varied recurrence risk indicated by standard tests (low or high risk) coupled with the genomic test (low, intermediate or high risk). For each vignette, women reported their perceived recurrence risk and treatment preferences. Test results indicating high recurrence risk increased perception of risk and preference for chemotherapy (p<.001 for all). Perceived risk explained (i.e., mediated) the effect of test results on chemotherapy preferences. When test results conflicted, women gave more weight to genomic over standard test results. Hypothetical genomic test results had the intended effect of influencing women's perceptions of recurrence risk and interest in chemotherapy.

Moderate-to-severe symptoms among survivors of early-stage breast cancer.

e19644 Background: This cross-sectional survey describes the prevalence of moderate/severe symptoms among patients in a survivorship clinic. Methods: We administered QoL questionnaires (FACT-B, SF-36, HADS) to pts. treated for stage I-III disease at a survivorship visit. For symptoms reported by at least 18/55 subjects, we identified risk factors using logistic regression. Results: Subjects (n=55) were age 55.9(+8.9) yrs at study, age 52.6(+9.3) at dx, and median 23.7 (range 6.3-157.2) mos. from dx of stage I (30.9%), II (54.5%), or III (14.6%) disease. Systemic treatment included chemotherapy only (20.0%), endocrine therapy only (30.9%), or both therapies (49.1%). Currently, 65.5% were on endocrine therapy. Symptoms experienced “quite a bit” or “very much” during the past wk were: hot flashes (45.5%), joint pain (30.9%), weight gain (30.9%), loss of libido (30.9%), vaginal dryness (27.3%), and night sweats (27.3%). In the past mo., 43.6% accomplished less than they would have liked due to physical health, and 30.9% felt worn out at least “a good bit of the time”. Sleep quality was rated “fairly to very bad” (32.7%), and 25.5% felt fatigued at least half the day during the past week. Vigorous activities were “limited a lot” for 36.4%, and increased with age at dx. Fre-quent hot flashes were associated with age &lt; 50 years (6.40, 1.75-23.35) and being within 1year of dx (10.67, 1.05-108.69). Adjusted for age at dx, poor quality of sleep increased with stage of disease (9.68, 2.25-41.69, per step increase) and was associated with having received endocrine therapy only (9.98, 1.40-71.03) and being within the first year after dx (9.54, 0.76-119.47). Conclusions: Limitation in activities, poor quality of sleep, and symptoms of hormonal suppression are common among survivors of early stage breast cancer. Poor quality sleep and frequent hot flashes appear to decrease in prevalence 1 yr after dx, but other common symptoms do not. A longitudinal cohort study is underway.
