Martin H, Saunders C, Redfern A, Hickey M. A Dedicated Menopausal After Cancer Clinic May Improve Adherence to Endocrine Therapy For Breast Cancer: A Population Based Study. Clin Breast Cancer 2024:S1526-8209(24)00230-1. [PMID: 39395849 DOI: 10.1016/j.clbc.2024.08.017] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/10/2024] [Revised: 07/10/2024] [Accepted: 08/20/2024] [Indexed: 10/14/2024]
Abstract
PURPOSE To examine utilization of a dedicated menopause symptoms after cancer clinic (MSAC) and to determine whether women referred to the MSAC for management of severe hot flush symptoms are more likely to adhere to endocrine therapy compare to those with severe symptoms not referred to MSAC. PATIENTS AND METHODS Breast cancer patients prescribed endocrine therapy with a diagnosis of estrogen-receptor positive breast cancer between January 2003 and December 2011 were identified from the Royal Perth Hospital Breast Unit database. Details of breast cancer pathology, endocrine therapy, endocrine therapy related side effects, referral to MSAC and patient reported adherence to endocrine therapy for up to 4 years were ascertained from the database and medical records systems. For those with severe vasomotor symptoms, total duration of endocrine therapy was compared between women referred to MSAC and those who were not referred to MSAC. RESULTS About 1275 women were identified from the database, with the cohort followed up until Dec 2016. Of these women, 120 (9.4%) were referred to MSAC and 1155 (90.1%) received usual care. In total, 147 reported severe vasomotor symptoms of whom almost half (71) were referred to MSAC. Women with severe vasomotor symptoms managed by MSAC were less likely to discontinue endocrine therapy (15.5%) compared with those managed with usual care (26.3%). However, this difference was not statistically significant (chi-square test statistic = 2.584, 1df, P = .1). CONCLUSION Management of severe vasomotor symptoms at a dedicated menopause clinic may increase adherence to endocrine therapy for breast cancer.

Pain 2024; 165:00006396-990000000-00608. [PMID: 38787639 PMCID: PMC11474918 DOI: 10.1097/j.pain.0000000000003283] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/17/2023] [Revised: 02/27/2024] [Accepted: 04/28/2024] [Indexed: 05/26/2024]
Abstract
ABSTRACT The profiles of muscle and joint pain throughout the menopausal transition and the factors associated with these symptoms have not been determined. A total of 609 participants from a longitudinal cohort study conducted in an urban Chinese community were enrolled in this study. We assessed the prevalence of musculoskeletal symptoms at different menopausal stages and explored the factors associated with these symptoms. The prevalence and severity of muscle and joint pain increase as menopausal stages progress, and late menopausal transition may be a crucial timepoint that triggers the onset of musculoskeletal pain. The results of the multivariate analysis revealed that poor health status (OR = 2.245, 95% CI = 1.714-2.94, P < 0.001), body mass index (BMI) (OR = 1.046, 95% CI = 1.01-1.084, P = 0.011), the presence of anxiety (OR = 1.601, 95% CI = 1.211-2.117, P < 0.001), and depression (OR = 1.368, 95% CI = 1.143-1.639, P < 0.001) were independently associated with muscle and joint pain. In addition, the severity of musculoskeletal pain was related to poor health status (OR = 2.738, 95% CI = 1.91-3.924, P < 0.001) and depression (OR = 1.371, 95% CI = 1.095-1.718, P = 0.006). Musculoskeletal symptoms are frequent somatic symptoms experienced by Chinese middle-aged women. Women with poor health status, high BMI, anxiety, and depression were at heightened risk of experiencing musculoskeletal pain. The severity of pain increased over time.

Association of Sarcopenia With Toxicity-Related Discontinuation of Adjuvant Endocrine Therapy in Women With Early-Stage Hormone Receptor-Positive Breast Cancer. Int J Radiat Oncol Biol Phys 2024; 118:94-103. [PMID: 37506979 DOI: 10.1016/j.ijrobp.2023.07.018] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Revised: 06/27/2023] [Accepted: 07/14/2023] [Indexed: 07/30/2023]
Abstract
PURPOSE Sarcopenia, an age-related decline in muscle mass and physical function, is associated with increased toxicity and worse outcomes in women with breast cancer (BC). Sarcopenia may contribute to toxicity-related early discontinuation of adjuvant endocrine therapy (aET) in women with hormone receptor-positive (HR+) BC but remains poorly characterized. METHODS AND MATERIALS This multicenter, retrospective cohort study included consecutive women with stage 0-II HR+ BC who received breast conserving therapy (lumpectomy and radiation therapy) and aET from 2011 to 2017 with a 5-year follow-up. Skeletal muscle index (SMI, cm2/m2) was analyzed using a deep learning model on routine cross-sectional radiation simulation imaging; sarcopenia was dichotomized according to previously validated reports. The primary endpoint was toxicity-related aET discontinuation; logistic regression analysis evaluated associations between SMI/sarcopenia and aET discontinuation. Cox regression analysis evaluated associations with time to aET toxicity, ipsilateral breast tumor recurrence (IBTR), and disease-free survival (DFS). RESULTS A total of 305 women (median follow-up, 89 months) were included with a median age of 67 years and early-stage BC (12% stage 0, 65% stage I). A total of 60 (20%) women experienced toxicity-related aET discontinuation. Sarcopenia was associated with toxicity-related early discontinuation of aET (odds ratio, 2.18; P = .036) and shorter time to aET toxicity (hazard ratio [HR], 1.62; P = .031). SMI or sarcopenia were not independently associated with IBTR or DFS; toxicity-related aET discontinuation was associated with worse IBTR (HR, 9.47; P = .002) and worse DFS (HR, 4.53; P = .001). CONCLUSIONS Among women with early-stage HR+ BC who receive adjuvant radiation therapy and hormone therapy, sarcopenia is associated with toxicity-related early discontinuation of aET. Further studies should validate these findings in women who did not receive adjuvant radiation therapy. These high-risk patients may be candidates for aggressive symptom management and/or alternative treatment strategies to improve outcomes.

Martin H, Redfern A. Bone mineral density fall during aromatase inhibitor treatment may predict lower breast cancer recurrence. Cancer Med 2024; 13:e6846. [PMID: 38186326 PMCID: PMC10807598 DOI: 10.1002/cam4.6846] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/30/2023] [Revised: 11/26/2023] [Accepted: 12/10/2023] [Indexed: 01/09/2024] Open
Abstract
PURPOSE Aromatase inhibitors (AIs) are associated with reduction in bone mineral density (BMD). The use of bone strengthening agents zoledronic acid and denosumab are associated with improved breast cancer outcomes for post-menopausal patients treated with AIs. This study investigates whether change in BMD with AI therapy is associated with breast cancer recurrence. METHODS A cohort of patients treated at a single institution diagnosed with hormone receptor-positive breast cancer with baseline BMD and subsequent BMD test while receiving adjuvant aromatase inhibitor therapy were studied. Demographic, treatment and outcome data was obtained. Simple and multiple linear regression analysis was performed to investigate predictors of annual percent BMD change at the LS and hip. Univariate and multivariate Cox proportional hazards modelling were undertaken to investigate predictors of breast cancer recurrence. RESULTS 353 patients eligible patients were identified. In multivariate analysis of lumbar spine BMD change, the difference between those in quartile 1, which showed the greatest reduction in BMD, and quartile 3, with substantially less reduction, was significant (HR = 3.02, 95% CI 1.15-7.90 p = 0.025). Hip BMD reduction was also not significantly associated with breast cancer recurrence. The two quartiles with the least reduction in hip BMD showing a non-significant reduced risk of recurrence relative to the quartile with the greatest (p = 0.10). CONCLUSIONS The findings suggest an association may exist between lumbar spine BMD change and breast cancer recurrence for patients treated with adjuvant AI. Further research is required to determine whether BMD change can be utilised as a biomarker.

Abstract
Cyclin-dependent kinase 4/6 inhibitors (CDK4/6i) in combination with endocrine therapy (ET) have been approved for breast cancer (BC) treatment. Several trials suggested that arthralgia was reduced in patients treated with ET plus CDK4/6i compared with that in those with ET-alone. We aimed to compare arthralgia rates in BC patients treated with/without CDK4/6i. We reviewed randomized controlled phase II/III trials investigating CDK4/6i with ET in hormone receptor-positive and epidermal growth factor 2-negative BC. Publications were retrieved from PubMed from January 2014 to April 2021. We compared arthralgia rates between patients who were administered ET plus CDK4/6i (CDK4/6i group) and those treated with ET-alone (control group). We reviewed 12 trials that reported data on adverse effects for arthralgia. These trials included 17,440 patients (9255 in the CDK4/6i group and 8185 in the control group). The arthralgia rate in the CDK4/6i group was significantly lower than that in the control group (27.6% vs. 34.8%, p < .001), especially in early BC (28.8% vs. 37.3%, p < .001). These suggested that the arthralgia rate in patients treated with ET plus CDK4/6i was lower than that in patients treated with ET-alone and that CDK4/6i may decrease the arthralgia rate in BC patients treated with ET, especially in early BC.

Abstract
Core temperature stability is the result of a dynamically regulated balance of heat loss and gain, which is not reflected by a simple thermometer reading. One way in which these changes manifest is in perceived thermal comfort, 'feeling too cold' or 'feeling too hot', which can activate stress pathways. Unfortunately, there is surprisingly little preclinical research that tracks changes in perceived thermal comfort in response to either disease progression or various treatments. Without measuring this endpoint, there may be missed opportunities to evaluate disease and therapy outcomes in murine models of human disease. Here, we discuss the possibility that changes in thermal comfort in mice could be a useful and physiologically relevant measure of energy trade-offs required under various physiological or pathological conditions.

Abstract
PURPOSE Adjuvant endocrine treatment is essential for treating luminal subtypes of breast cancer, which constitute 75% of all breast malignancies. However, the detrimental side effects of treatment make it difficult for many patients to complete the guideline-required treatment. Such non-adherence may jeopardize the lifesaving ability of anti-estrogen therapy. In this systematic review, we aimed to assess the consequences of non-adherence and non-persistence from available studies meeting strict statistical and clinical criteria. METHODS A systematic literature search was performed using several databases, yielding identification of 2,026 studies. After strict selection, 14 studies were eligible for systematic review. The review included studies that examined endocrine treatment non-adherence (patients not taking treatment as prescribed) or non-persistence (patients stopping treatment prematurely), in terms of the effects on event-free survival or overall survival among women with non-metastatic breast cancer. RESULTS We identified 10 studies measuring the effects of endocrine treatment non-adherence and non-persistence on event-free survival. Of these studies, seven showed significantly poorer survival for the non-adherent or non-persistent patient groups, with hazard ratios (HRs) ranging from 1.39 (95% CI, 1.07 to 1.53) to 2.44 (95% CI, 1.89 to 3.14). We identified nine studies measuring the effects of endocrine treatment non-adherence and non-persistence on overall survival. Of these studies, seven demonstrated significantly reduced overall survival in the groups with non-adherence and non-persistence, with HRs ranging from 1.26 (95% CI, 1.11 to 1.43) to 2.18 (95% CI, 1.99 to 2.39). CONCLUSION The present systematic review demonstrates that non-adherence and non-persistence to endocrine treatment negatively affect event-free and overall survival. Improved follow-up, with focus on adherence and persistence, is vital for improving health outcomes among patients with non-metastatic breast cancer.

Short-term changes in ultrasound tomography measures of breast density and treatment-associated endocrine symptoms after tamoxifen therapy. NPJ Breast Cancer 2023; 9:12.

Abstract
Although breast density decline with tamoxifen therapy is associated with greater therapeutic benefit, limited data suggest that endocrine symptoms may also be associated with improved breast cancer outcomes. However, it is unknown whether endocrine symptoms are associated with reductions in breast density after tamoxifen initiation. We evaluated treatment-associated endocrine symptoms and breast density change among 74 women prescribed tamoxifen in a 12-month longitudinal study. Treatment-associated endocrine symptoms and sound speed measures of breast density, assessed via novel whole breast ultrasound tomography (m/s), were ascertained before tamoxifen (T0) and at 1-3 (T1), 4-6 (T2), and 12 months (T3) after initiation. CYP2D6 status was genotyped, and tamoxifen metabolites were measured at T3. Using multivariable linear regression, we estimated mean change in breast density by treatment-associated endocrine symptoms adjusting for age, race, menopausal status, body mass index, and baseline density. Significant breast density declines were observed in women with treatment-associated endocrine symptoms (mean change (95% confidence interval) at T1:-0.26 m/s (-2.17,1.65); T2:-2.12 m/s (-4.02,-0.22); T3:-3.73 m/s (-5.82,-1.63); p-trend = 0.004), but not among women without symptoms (p-trend = 0.18) (p-interaction = 0.02). Similar declines were observed with increasing symptom frequency (p-trends for no symptoms = 0.91; low/moderate symptoms = 0.03; high symptoms = 0.004). Density declines remained among women with detectable tamoxifen metabolites or intermediate/efficient CYP2D6 metabolizer status. Emergent/worsening endocrine symptoms are associated with significant, early declines in breast density after tamoxifen initiation. Further studies are needed to assess whether these observations predict clinical outcomes. If confirmed, endocrine symptoms may be a proxy for tamoxifen response and useful for patients and providers to encourage adherence.

Abstract
OBJECTIVES Most patients report pain while taking adjuvant endocrine therapy (AET) for the treatment of breast cancer. While studies have examined patients' experiences with side effects, none solely capture patients' experiences with AET-related pain, a troubling symptom that reduces quality of life and impairs treatment adherence. This study explored themes of AET-related pain to inform future intervention development. METHODS Between November 2017 and November 2018, female patients (n = 30) with early-stage breast cancer enrolled between 3 and 36 months post-initiation of AET. Purposeful sampling was stratified by adherence level, age, distress level and time taking AET. Study staff conducted, transcribed and coded semi-structured interviews via inductive thematic coding to identify pain-related themes and achieved high inter-coded reliability (Kappa = 0.96). RESULTS Several pain-related themes were observed. Attitudes around pain are generally negative, and management needs are largely unmet. Patients reported preferences for non-pharmacological management strategies and cited AET pain as a reason for medication breaks but not discontinuation. Patients within 19 months of starting AET and low adherers reported more intense and disruptive pain. CONCLUSIONS Patients' experiences varied by patient attributes and revealed modifiable factors that may be targeted through behavioural interventions. AET-related pain is a complex side effect for which psychosocial support may be beneficial.

Abstract
BACKGROUND Clinical trials have shown that adjuvant hormone therapy (AHT)-related hot flashes can predict better breast cancer outcomes. This population-based cohort study investigated whether this result can be generalized to a real-world setting. PATIENTS AND METHODS By linking the National Quality Registry for Breast Cancer, Prescribed Drug Register, and Cause-of-Death Register, we identified 7,152 chemotherapy-free patients with breast cancer who initiated AHT in Stockholm from 2006 through 2019, and followed them until 2020. Hot flashes were defined as new use of drugs for hot flashes within 6 months after initiating AHT. We used Cox models to compare disease-free survival and treatment discontinuation among patients with and without hot flashes. RESULTS Patients who newly used drugs for hot flashes shortly after AHT initiation had worse disease-free survival (adjusted hazard ratio [HR], 1.67; 95% CI, 1.11-2.52) and a higher treatment discontinuation rate (adjusted HR, 1.47; 95% CI, 1.21-1.78). The association between drugs for hot flashes and discontinuation of AHT differed by patient characteristics, with stronger associations among low-income patients (HR, 1.91; 95% CI, 1.41-2.59) and those without first-degree relatives who had cancer (HR, 1.81; 95% CI, 1.39-2.35) or died from cancer (HR, 1.71; 95% CI, 1.37-2.12). CONCLUSIONS AHT-related hot flashes predict worse, rather than better, breast cancer outcomes among patients in clinical routine practice. The identification of adverse effects by the initiation of hot flash medications may identify a subset of patients with more severe hot flashes who are more likely to discontinue AHT and need more support for treatment adherence.

Patient- versus physician-reported outcomes in a low-dose tamoxifen trial in noninvasive breast cancer. Breast J 2021; 27:817-823. [PMID: 34626060 DOI: 10.1111/tbj.14296] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/19/2021] [Revised: 09/28/2021] [Accepted: 09/28/2021] [Indexed: 12/09/2022]
Abstract
BACKGROUND We recently conducted a de-escalation trial of low-dose tamoxifen 5 mg/day ("babytam", BT) or placebo given for 3 years in 500 women with noninvasive breast cancer. Women on babytam had a 52% reduction of recurrence (invasive breast cancer or DCIS) after 5 years. Since menopausal symptoms are major reasons for treatment withdrawal during tamoxifen preventive therapy, we compared and analyzed the patient-reported outcomes (PROs) with the physician-reported adverse events and studied their association with recurrence. METHODS Menopausal symptoms recorded by physicians using the Common Terminology Criteria (CTCAEs) were compared with a patient self-reported validated questionnaire reviewed by a research nurse at baseline and every 6 months up to 36 months. Hot flashes (HF), the main outcome measure, were detected through a self-report 7-day diary for frequency and intensity. Treatment adherence and efficacy were assessed by the Kaplan-Meier curves and the Cox model. RESULTS The number of HF events at 12, 24, and 36 months for PROs versus CTCAEs was 246 versus 12, 238 versus 8, and 210 versus 4, respectively. The majority of events were grade 1. There was no difference in PROs between babytam and placebo except for HF daily frequency, which increased by 1.5 events (95% CI, 1.1-1.8) on placebo to 2.1 on babytam (95% CI, 1.7-2.5, p = 0.05). The presence of HF at baseline was a favorable prognostic factor for recurrence and a predictive factor for response to babytam. Adherence was similar between babytam and placebo. CONCLUSIONS The use of PROs is effective for identifying frequent mild grade menopausal symptoms which are underestimated by physicians but important prognostic and predictive factors. Research nurse can use these results as a tool to reassure patients about symptoms, improve adherence to treatment, and limit dropouts.

Abstract
Adjuvant endocrine therapy (AET) is recommended after hormone receptor-positive breast cancer to reduce risk of recurrence, but adherence is sub-optimal in many women. Behavioral interventions have been ineffective in improving adherence rates to AET. This qualitative descriptive study investigates factors that support women in AET use and suggestions for interventions to improve AET use and management. Interviews with women who persisted with AET (n = 23), women who discontinued AET (n = 15), and healthcare providers (HCPs; oncologists, oncology residents, and pharmacists; n = 9) were conducted, transcribed, and described using thematic analysis. Data collection stopped once saturation occurred (i.e., no new codes or themes emerged during interviews). Two researchers created codes and developed themes in an iterative process; a third researcher verified the representativeness of final themes. This study was approved by the Health Research Ethics Board of Alberta (ID: HREBA.CC-17-0513). Women who persisted described being prepared for side effects and having self-management strategies, strong rationale for AET use, supportive HCPs, and available resources as relevant factors. Women who discontinued described feeling overwhelmed by side effects, information needs, drawbacks of AET, helpful/unhelpful experiences with HCPs, and contextual factors as relevant to their discontinuation. HCPs described health system-related and patient-related barriers, side effect management, and patient-provider interactions as relevant to supporting AET use. The considerable overlap in themes among the three groups suggests broad recognition of salient factors relevant to AET use and that associated strategies to improve use may be acceptable to patients and providers alike. Factors supporting AET use could include the following: education (which may be necessary but insufficient), developing a strong personal rationale for use, being prepared for side effects, having side effect management strategies, reciprocal communication between patients and HCPs, and accessible resources.

Abstract
PURPOSE Despite the efficacy of adjuvant endocrine therapy (AET) in reducing breast cancer recurrence and mortality, suboptimal AET adherence is common and hence an important clinical issue among breast cancer survivors. Delineating potentially modifiable patient-level factors associated with AET adherence may support the development of successful adherence-enhancing interventions. PATIENTS AND METHODS The present study included 133 breast cancer survivors prescribed AET recruited from a cancer pharmacy. Women completed a baseline questionnaire examining psychosocial factors and self-reported adherence and consented to their prescription records being monitored for the proceeding 12 months to ascertain proportion of days covered (PDC), an objective measure of adherence. Regression analyses were used to identify the factors most strongly associated with both self-reported and objective adherence. Exploratory moderation analyses examined whether factors were differentially associated with adherence based on AET type (aromatase inhibitors or tamoxifen). RESULTS Adherence was high in this sample (PDC over 12 months was 95%). Side effect severity was most strongly associated with self-reported adherence, followed by self-efficacy, and medication/healthcare system-related barriers. Medication/healthcare system-related barriers was the only factor that uniquely predicted objective adherence. Within medication/healthcare system-related barriers, fear of side effects was most strongly associated with both measures of adherence. There were no significant interactions between AET type and potentially modifiable factors in predicting self-reported or objective adherence. CONCLUSION Side effects, reactions to side effects, and self-efficacy may represent modifiable targets through which AET adherence can be improved. Associations between potentially modifiable factors and adherence did not vary by AET type, despite distinct side-effect profiles.

Abstract
Aromatase inhibitors (AIs) are a key component in the chemoprevention and treatment of hormone receptor-positive (HR+) breast cancer. While the addition of AI therapy has improved cancer-related outcomes in the management of HR+ breast cancer, AIs are associated with musculoskeletal adverse effects known as the aromatase inhibitor-associated musculoskeletal syndrome (AIMSS) that limit its tolerability and use. AIMSS is mainly comprised of AI-associated bone loss and arthralgias that affect up to half of women on AI therapy and detrimentally impact patient quality of life and treatment adherence. The pathophysiology of AIMSS is not fully understood though has been proposed to be related to estrogen deprivation within the musculoskeletal and nervous systems. This review aims to characterize the prevalence, risk factors, and clinical features of AIMSS, and explore the syndrome's underlying mechanisms and management strategies.

Abstract
BACKGROUND Studies in the adjuvant setting have shown that endocrine therapy related side effects predict breast cancer recurrence risk. Here, we assess the relationship between early reported side effects and incidence of breast cancer in women randomised to tamoxifen for cancer prevention in the International Breast Intervention Study (IBIS)-I trial. METHODS Women randomised to tamoxifen in the IBIS-I trial and for whom side effect status was known at the 6-month follow-up visit were included in this analysis. Side effects included in this analysis were hot flushes, vaginal discharge, and vaginal dryness. The primary endpoint was all breast cancer and secondary endpoint was oestrogen receptor (ER) positive breast cancer. Cox proportional hazard models were used to investigate breast cancer incidence in the tamoxifen group with and without side effects reported within 6 months of randomisation. RESULTS Women randomised to tamoxifen and reporting hot flushes at the 6-month follow-up visit had a non-statistically significant increase in breast cancer compared to those without hot flushes (HR = 1.26 (0.98-1.62), P = 0.08). A significant higher breast cancer risk was observed for postmenopausal women who reported hot flushes at the 6-month follow-up visit compared to those without hot flushes (HR = 1.59 (1.12-2.26), P = 0.01). A higher risk was observed for ER-positive breast cancer in postmenopausal women (HR = 1.81 (1.19-2.74), P = 0.01). No significant associations between gynaecological side effects and breast cancer occurrence was observed. CONCLUSIONS Overall, no association between side effects reported at 6 months and subsequent breast cancer occurrence was observed. Some side effects might be useful markers for breast cancer occurrence in postmenopausal women.

Abstract
Aim: To evaluate plasma endoxifen levels and metabolic phenotype-associated factors in Mexican Mestizo patients under tamoxifen treatment. Patients & methods: A total of 138 breast cancer patients under tamoxifen treatment were cross-sectionally evaluated and side effects (SE) were recorded. CYP2D6 genetic phenotypes (GP) and metabolic phenotypes (MP) were assessed (metabolic poor [mPM], intermediate [mIM], normal [mNM], and ultrarapid [mUM] metabolizer). Associations were tested in uni-multivariate models for endoxifen >5.9 ng/ml and for mNM + mUM MP. Results: The main SE was hot flashes (62%). Distribution of the CYP2D6 MP was 4.3% mPM; 14.5% mIM; 75.4% mNM; and 5.8% mUM. Endoxifen >5.9 ng/ml was partially associated with SE (p = 0.06); the mNM + mUM MP was associated with treatment time (p = 0.03). Conclusion: The endoxifen-associated factors in Mexican Mestizo patients remain inconclusive, although treatment time was associated with MP.

Abstract
Aromatase inhibitor-induced musculoskeletal symptoms (AIMSS) were first recognized as a distinct entity in 2001, 5 years after the approval of the first aromatase inhibitor, anastrozole. Musculoskeletal symptoms can severely affect patients' quality of life and also lead to premature discontinuation of aromatase inhibitor therapy. Several interventions for managing AIMSS have been investigated in the last decade, with some demonstrating promise. This article provides an evidence-based summary to guide practicing oncologists in regard to the epidemiology, prevention, and treatment of AIMSS.

Abstract
Background Breast cancer patients' self-understanding of their disease can impact their quality of life (QoL); the relationship between compliance and QoL is poorly understood. Patients and Methods The Patient's Anastrozole Compliance to Therapy (PACT) program, a prospective, randomized study, investigated the effect of additional patient information material (IM) packages on compliance with adjuvant aromatase inhibitor (AI) therapy in postmenopausal women with hormone receptor-positive early breast cancer. The QoL subanalysis presented here examined the impact of IM packages on QoL and the association between QoL and compliance. European Organization for Research and Treatment of Cancer (EORTC) QLQ-C30 and QLQ-BR23 questionnaires were completed at baseline, 12 and 24 months, or study termination to assess health-related QoL and disease-related symptoms. Results Of the 4,844 patients randomized to standard therapy or standard therapy + IM packages (1:1), 4,253 were available for QoL analysis. No difference in QoL was observed between groups at baseline. IM packages did not have a statistically significant impact on patient QoL at the 12- or 24-month follow-up. Compliant patients experienced improvement in multiple items across the QLQ-C30 and QLQ-BR23 scales at 12 months. However, those results should be interpreted carefully due to limitations in the statistical analyses. Conclusions Provision of IM packages did not influence patients' QoL or satisfaction with care during AI therapy. Compliant patients appear to experience improved QoL compared to noncompliant patients, perhaps indicating a more self-empowered perception of their condition.

Abstract
This is a case report of corneal deposits noted in a 69-year-old female patient taking the aromatase inhibitor, exemestane, after undergoing a mastectomy and chemotherapy for breast cancer. The patient presented to our eye clinic for a new-onset floater in one eye, and bilateral subepithelial opacities were found incidentally on exam. The patient completed a 5-year course of the medication shortly after her initial visit with us and was noted to have a slight improvement in the density of the opacities on a follow-up visit 3 months later. We believe these corneal changes were most likely secondary to exemestane. The effect of aromatase inhibitors on the eye deserves further exploration as an increasing number of patients are prescribed these medications.

Abstract
OBJECTIVE Vasomotor symptoms (VMS) including hot flashes and night sweats are common during the menopausal transition and may persist. Although VMS pathophysiology is complex, estrogen's efficiency as VMS therapy suggests hormonal environment change may influence this process. As studies of VMS and breast cancer are inconsistent, we examined associations between persistent VMS and breast cancer incidence and mortality. METHODS The analytic sample included 25,499 postmenopausal women aged 50 to 79 in the Women's Health Initiative (WHI) without current/former menopausal hormone therapy use with information on VMS status (never vs persistent). Breast cancers were verified by medical record review. Cause of death attribution was enhanced by serial National Death Index queries. Associations between VMS status and breast cancer incidence and mortality was determined using time dependent Cox regression analyses adjusted for breast cancer risk factors. RESULTS Through 17.9 years (median) follow-up, 1,399 incident breast cancers were seen. Women with persistent VMS (VMS median duration 10+ years) (n = 9,715), compared to women with never VMS (n = 15,784), had a higher breast cancer incidence (hazard ratio [HR] 1.13 95% confidence interval [CI] 1.02-1.27). While breast cancer-specific mortality was higher in women with persistent VMS (HR 1.33 95% CI 0.88-2.02), the difference was not statistically significant. Persistent VMS status had no influence on breast cancer overall survival (HR 1.02 95% CI 0.81-1.29). CONCLUSION Women with persistent VMS are more likely to be diagnosed with breast cancer than women who never experienced VMS, but not more likely to die from breast cancer.

Abstract
CONTEXT Women with breast cancer treated with aromatase inhibitor (AI) therapy experience multiple concurrent symptoms or symptom clusters. Understanding of the symptom experience and identifying symptom clusters before and during AI therapy are important for the development of interventions to improve clinical outcomes. OBJECTIVES The aim of this study was to identify symptom clusters experienced by women with breast cancer treated with AI therapy from pre-adjuvant therapy up to 18 months of adjuvant therapy using a broad scope of symptoms assessment. METHODS Forty-seven symptoms were evaluated in postmenopausal women with breast cancer (N = 354) who received AI therapy or chemotherapy followed by AI therapy. Symptoms were assessed at four semiannual time points with the Breast Cancer Prevention Trial Symptom Checklist, Patient's Assessment of Own Functioning Inventory, Beck Depression Inventory-II, and Profile of Mood States Tension/Anxiety and Fatigue/Inertia subscales. Exploratory factor analyses were conducted at each time point to identify symptom clusters. RESULTS Four stable symptom clusters (i.e., musculoskeletal, vasomotor, urinary, sexual) and three relatively stable symptom clusters (i.e., psychological, neurocognitive, weight) were identified across the 18-month follow-up period. The gastrointestinal symptom cluster only appeared at after six months of adjuvant therapy (postchemotherapy). CONCLUSION This study helps us to better understand the most common symptom clusters over the first 18 months of adjuvant therapy among postmenopausal women with early-stage breast cancer. It is critical for health care providers to know the symptom clusters commonly experienced by women receiving AI therapy with or without chemotherapy and manage them properly over time.

Tamoxifen-induced severe hot flashes and endoxifen levels: is dose reduction a safe and effective strategy? Breast 2019; 46:52-57. [PMID: 31082762 DOI: 10.1016/j.breast.2019.05.009] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/26/2018] [Revised: 04/17/2019] [Accepted: 05/03/2019] [Indexed: 10/26/2022] Open
Abstract
OBJECTIVES Severe hot flash (HF) toxicity due to tamoxifen can compromise compliance. We previously found that HFs did not correlate with endoxifen level or CYP2D6 genotype. In this study, we reduced tamoxifen dose in patients with severe HFs to determine whether HFs were ameliorated whilst maintaining a purported therapeutic endoxifen level of >15 nM. MATERIALS AND METHODS Twenty patients with severe HFs on 20 mg TAM had CYP2D6genotype, trough level tamoxifen and metabolites measured with Loprinzi HF scores (HFS) derived before and after DR of tamoxifen to 10 mg. Other data collected included demographics, smoking, alcohol, menstrual and breast cancer history, previous chemotherapies, concurrent medications, BMI and other tamoxifen toxicities. RESULTS At the 20 mg tamoxifen dose, endoxifen levels were 25.6, 0-91.9 nM (median, range) with HFS 131, 22-1482 (median, range). Upon DR to 10 mg, median endoxifen level fell to 14.1, 0.6-71.9 nM (difference in means p = 0.11, two-tailed T test) with HFS 47, 5-864 (difference in means p = 0.24, two-tailed T test). Despite lacking statistical significance, 85% of patients reported subjective improvement of HFs with DR. After DR, the proportion of patients with endoxifen level <15 nM increased from 20% to 50%. HFS did not correlate with any other parameter. CONCLUSION DR of tamoxifen from 20 mg to 10 mg daily resulted in halving of endoxifen levels and subjective improvement of HF. While half the dose-reduced patients were below a potential therapeutic level of endoxifen, other recent studies suggest that low endoxifen levels may not indicate reduced effectiveness of tamoxifen.

Pharmacogenomic-pharmacokinetic study of selective estrogen-receptor modulators with intra-patient dose escalation in breast cancer. Breast Cancer 2019; 26:535-543.

Abstract
BACKGROUND An association between CYP2D6 polymorphisms and tamoxifen (TAM) efficacy has not been confirmed, partly due to unreliable prediction of active metabolite exposure solely by CYP2D6 activity. The efficacy of TAM dose escalation appears limited in poor TAM metabolizers. Since the chlorine atom on the side chain of toremifene (TOR) prevents 4-hydroxylation by CYP2D6, its contribution to active conversion of TOR is minor. We examined the role of TOR and its dose escalation among poor TAM metabolizers. METHODS The pharmacokinetics (PK) and pharmacogenomics (PGx) of TAM and TOR were studied. Correlation between PK and CYP2D6 inhibitor use, smoking status, and PGx were examined by regression analysis. For patients showing low endoxifen levels, an intra-patient dose escalation of TOR was conducted, and TOR was increased from 40 to 120 mg for ≥ 24 weeks with PK sampling. Total activity was calculated as the sum of the concentration of each active metabolite adjusted by their respective in vitro activities. RESULTS Fifty and 11 of the 273 participating patients had endoxifen levels < 15 and < 7.5 ng/mL, respectively. The CYP2D6 genotype was the major determinant for TAM activity (p < 0.01). Smoking status (p = 0.07) and the CYP2C19 phenotype (p = 0.07), but not the CYP2D6 genotype (p = 0.61), showed marginally significant effects on TOR activity. TOR activity increased significantly with dose escalation, even among poor TAM metabolizers, and was maintained for ≥ 24 weeks. CONCLUSION TOR might be a valid alternative to TAM in patients predicted to be poor TAM metabolizers.

Abstract
BACKGROUND Aromatase inhibitors are the mainstay of therapy for patients with hormone receptor-positive breast cancer in both adjuvant and metastatic settings. Their use in clinical practice has been challenged by significant inter-individual variability in response and tolerability. Hence, the purpose of this paper is to provide a succinct review of the literature on the genetic factors contributing to this variability. DESIGN A systematic search in PUBMED was conducted to identify studies that investigated the association between germline polymorphisms and disposition, clinical response and toxicities of aromatase inhibitors, as well as those evaluating the implications of mutations in ESR1 on clinical response. RESULTS Polymorphisms in genes coding for phase I and phase II enzymes (pharmacokinetic genes) significantly modulated exposure to aromatase inhibitors; however, there is a paucity of data linking interindividual variability in drug exposure to clinical response. Furthermore, pharmacogenetic studies interrogating relationship between polymorphisms in CYP19A1 (the target site of aromatase inhibitors, i.e. a pharmacodynamic gene) and response yielded conflicting results. Acquired mutations in ESR1 receptors have been identified as the underlying mechanism of resistance to aromatase inhibitors, and likely predict drug response. Although some pharmacogenetic studies have implicated polymorphisms in CYP19A1 and ESR1 with drug-related side effects, the putative role of these genes in predicting toxicity warrants further validation. CONCLUSION Genetic polymorphisms in pharmacokinetic and pharmacodynamic genes appear to influence aromatase inhibitor disposition, response and/or toxicity; however, prospective interventional studies are needed to understand the application of genomics to personalize aromatase inhibitor therapy in breast cancer patients.

Abstract
Purpose There are few reports from Asian countries about the long-term results of aromatase inhibitor adjuvant treatment for breast cancer. This observational study aimed to evaluate the long-term effects of letrozole in postmenopausal Korean women with operable breast cancer. Methods Self-reported quality of life (QoL) scores were serially assessed for 3 years during adjuvant letrozole treatment using the Korean version of the Functional Assessment of Cancer Therapy-Breast questionnaires (version 3). Changes in bone mineral density (BMD) and serum cholesterol levels were also examined. Results All 897 patients received the documented informed consent form and completed a baseline questionnaire before treatment. Adjuvant chemotherapy was administered to 684 (76.3%) subjects, and 410 (45.7%) and 396 (44.1%) patients had stage I and II breast cancer, respectively. Each patient completed questionnaires at 3, 6, 12, 18, 24, 30, and 36 months after enrollment. Of 897 patients, 749 (83.5%) completed the study. The dropout rate was 16.5%. The serial trial outcome index, the sum of the physical and functional well-being subscales, increased gradually and significantly from baseline during letrozole treatment (p<0.001). The mean serum cholesterol level increased significantly from 199 to 205 after 36 months (p=0.042). The mean BMD significantly decreased from −0.39 at baseline to −0.87 after 36 months (p<0.001). Conclusion QoL gradually improved during letrozole treatment. BMD and serum cholesterol level changes were similar to those in Western countries, indicating that adjuvant letrozole treatment is well tolerated in Korean women, with minimal ethnic variation.

Abstract
PURPOSE Aromatase inhibitors are the most commonly prescribed adjuvant endocrine therapy for hormone-dependent early breast cancer in postmenopausal women. Among Canadian Cancer Trials Group MA.27 participants, anastrozole and exemestane had comparable 5-year event-free survival. This companion study examined differences in patient-reported treatment-related symptoms (TRS) and health-related quality of life (HRQL) among postmenopausal women randomized to anastrozole or exemestane. METHODS MA.27 participants (N = 686, of 7576) randomized to 5 years of anastrozole (1 mg/day, n = 371, Arm A) or exemestane (25 mg/day, n = 315, Arm E) completed the 56-item Functional Assessment of Cancer Therapy-Endocrine Symptoms (FACT-ES) questionnaire to assess TRS and HRQL. The FACT-ES was completed at baseline, 3, 6, 12, and 24 months. RESULTS No significant differences in FACT-ES median scores measuring TRS and HRQL were observed between treatment arms at any time point. Change in TRS from baseline was statistically significant at 3, 6, 12, and 24 months. HRQL was stable over time in both arms. Greater TRS burden was associated with poorer HRQL (coefficient = 0.57, p < 0.001). Twenty percent of patients discontinued AI therapy by month 24 and 32% discontinued AIs at 4 years. In both arms, patients reporting more side effect bother prior to initiating study treatment had a higher risk of discontinuing treatment before completing protocol therapy (hazard ratio [HR] 1.29, 95% CI 1.08-1.55, p = 0.01). CONCLUSIONS TRS and HRQL were comparable between anastrozole and exemestane. TRS negatively affect HRQL. Women who report being bothered by treatment side effects prior to initiating an AI are at increased risk for early treatment discontinuation.

Abstract
BACKGROUND Endocrine treatment (ET) with an aromatase inhibitor (AI) is the treatment of choice in post-menopausal patients with hormone receptor-positive early breast cancer (EBC). However, adverse events (AEs) often lead to treatment discontinuation. This analysis aimed to identify side-effects that lead to patients failing to persist with letrozole treatment. PATIENTS AND METHODS Post-menopausal hormone receptor-positive EBC patients starting ET with letrozole were enroled in EvAluate-TM, a non-interventional study. Information regarding treatment compliance and persistence was gathered in months 6 and 12. Persistence was defined as the time from 30 d after the start to the end of treatment. The influence on persistence of musculoskeletal syndrome, menopausal disorder, sleep disorder and other AEs within the first 30 d was analysed using Cox regression analyses. RESULTS Among 3887 patients analysed, the persistence rate after 12 months was >85%. In all, 568 patients (14.6%) discontinued the treatment, 358 of whom (63.0%) did so only because of side-effects. The main AEs influencing persistence were musculoskeletal symptoms (hazard ratio [HR] 2.55; 95% confidence interval [CI], 1.90-3.42), sleep disorders (HR 1.95; 95% CI, 1.41-2.70) and other AEs (HR 2.03; 95% CI, 1.51-2.73). Menopausal disorder was not associated with non-persistence (HR 1.17; 95% CI, 0.74-1.84). CONCLUSIONS These results suggest that side-effects of AIs such as musculoskeletal syndrome and sleep disorder lead to ET discontinuation within the first treatment year in significant numbers of EBC patients. Compliance programmes adapted for subgroups that are at risk for early non-persistence might help to ensure the recommended therapy duration. CLINICAL TRIALS NUMBER CFEM345DDE19.

Abstract
Purpose An association between endocrine treatment-related symptoms and breast cancer recurrence has been suggested previously; however, conflicting results have been reported. We performed a meta-analysis of published studies to clarify this relationship. Methods We systematically searched PubMed, Embase, Scopus, and the Cochrane database for studies investigating the association between endocrine treatment-related symptoms and patient survival. Random-effects meta-analysis was conducted with recurrence rate as the primary outcome. Results Out of 7,713 retrieved articles, six studies were included. In patients who received endocrine treatment, the presence of any endocrine treatment-related symptom was found to be associated with a lower recurrence rate in comparison to an absence of any symptoms (hazard ratio [HR], 0.76; 95% confidence interval [CI], 0.66-0.87). This relationship persisted in patients presenting with only vasomotor or only musculoskeletal symptoms (HR, 0.74, 95% CI, 0.63-0.87; HR, 0.69, 95% CI, 0.55-0.86, respectively). At both time-points of symptom evaluation (3 months and 12 months), patients with endocrine treatment-related symptoms had a lower recurrence rate (HR, 0.74, 95% CI, 0.66-0.84; HR, 0.79, 95% CI, 0.69-0.90, respectively). This association was also significant in pooled studies including patients with and without baseline symptoms (HR, 0.73, 95% CI, 0.54-0.99; HR, 0.76, 95% CI, 0.69-0.85, respectively). Conclusion Endocrine treatment-related symptoms are significantly predictive of lower recurrence rate in breast cancer patients, regardless of the type of symptoms, time-point of evaluation, or inclusion of baseline symptoms. These symptoms could be biomarkers for the prediction of long-term responses to endocrine treatment in patients with breast cancer.

Abstract
Background Anastrozole reduces breast cancer risk in women at high risk, but implementing preventive therapy in clinical practice is difficult. Here, we evaluate adherence to anastrozole in the International Breast Cancer Intervention Study (IBIS)-II prevention and ductal carcinoma in situ (DCIS) trials, and its association with early symptoms. Patients and methods In the prevention trial, 3864 postmenopausal women were randomized to placebo versus anastrozole. A total of 2980 postmenopausal women with DCIS were randomized to tamoxifen versus anastrozole. Adherence to trial medication was calculated using the Kaplan-Meier method and all P-values were two-sided. Results In the prevention trial, adherence was 65.8% [anastrozole (65.7%) versus placebo (65.9%); HR = 0.97 (0.87-1.09), P = 0.6]. Adherence was lower for those reporting arthralgia in the placebo group (P = 0.02) or gynecological symptoms in the anastrozole group (P = 0.003), compared with those not reporting these symptoms at 6 months. In the DCIS study, adherence was 66.7% [anastrozole (67.5%) versus tamoxifen (65.8%); HR = 1.06 (0.94-1.20), P = 0.4]. Hot flashes were associated with greater adherence in the anastrozole arm (P = 0.02). In both studies, symptoms were mostly mild or moderately severe, and adherence decreased with increasing severity for most symptoms. Drop-outs were highest in the first 1.5 years of therapy in both trials. Conclusions In the IBIS-II prevention and DCIS trials, over two-thirds of women were adherent to therapy, with no differences by treatment groups. Participants who reported specific symptoms in the IBIS-II prevention trial had a small but significant effect on adherence, which strengthened as severity increased. Strategies to promote adherence should target the first year of preventive therapy.

Ageing perceptions and non-adherence to aromatase inhibitors among breast cancer survivors. Eur J Cancer 2018; 91:145-152. [PMID: 29329697 DOI: 10.1016/j.ejca.2017.12.006] [Citation(s) in RCA: 20] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 09/28/2017] [Revised: 11/28/2017] [Accepted: 12/02/2017] [Indexed: 01/23/2023]
Abstract
PURPOSE Aromatase inhibitors (AIs) are a potentially life-saving treatment for breast cancer survivors, yet poor adherence to treatment is a prevalent problem. A common adverse effect of AI treatment is arthralgia, which is identified by survivors as a major reason for treatment discontinuation. Women who experience arthralgia on AIs often report feeling they have aged rapidly while on the treatment. In the present study, we examined whether arthralgia-associated ageing perceptions predicted non-adherence. PATIENTS AND METHODS We conducted a prospective cohort study among women with stage I-III breast cancer, who were on an AI and completed the Penn Arthralgia Aging Scale within 2 years of AI initiation. Adherence data were abstracted from medical charts by trained raters. Cox proportional hazard analysis was used to determine the relationship between ageing perceptions and time to non-adherence. All analyses included adjustments for joint pain severity. RESULTS Among 509 participants, 144 (28.3%) were non-adherent. As hypothesised, women with high levels of ageing perceptions were at greater risk of non-adherence than women with low levels of ageing perceptions (adjusted hazard ratio [HR], 1.71; 95% confidence interval [CI], 1.10-2.67; p = .02). High levels of depressive symptoms were also uniquely associated with increased risk of non-adherence (adjusted HR, 1.63; 95% CI, 1.03-2.59; p = .04). CONCLUSION Perceptions of ageing related to arthralgia and depressive symptoms predicted non-adherence to AIs. These findings suggest that interventions that address negative beliefs about ageing due to AI-related arthralgia and depressive mood can potentially improve rates of adherence to AIs.

Abstract
PURPOSE Although adjuvant polychemotherapy improves outcomes for early breast cancer, the significant variability in terms of pharmacokinetics results in differences in efficacy and both short and long-term toxicities. Retrospective studies support the use of dose tailoring according to the hematologic nadirs. METHODS The SBG 2004-1 trial was a randomized feasibility phase II study which assessed tailored dose-dense epirubicin and cyclophosphamide (EC) followed by docetaxel (T) (group A), the same regimen with fixed doses (group B) and the TAC regimen (group C). Women aged 18-65 years, ECOG PS 0-1 with at least one positive axillary lymph node were randomized 1:1:1. The primary endpoint of the study was the safety and feasibility of the treatment. Toxicity was graded according to CTC-AE version 3.0. The design and short-term toxicity have been previously published. Here, we report safety and efficacy data after 10 years of follow-up. RESULTS A total of 124 patients were included in the study. After a median follow-up of 10.3 years, the probability for 10-year survival was 78.5, 75.1, and 63.4% and for relapse free survival 64.1, 71.0, and 59.5% for groups A, B, and C, respectively. There were no cases of clinically diagnosed cardiotoxicity or hematologic malignancies. No patient was lost to follow-up. CONCLUSIONS In this randomized phase II trial, tailored dose adjuvant chemotherapy was feasible, without an increased risk for long-term adverse events after a median follow-up of 10 years.

Abstract
The deciphering of the hedgehog (Hh) signalling pathway implicated in the tumorigenesis of basal cell carcinoma (BCC) led to the development of targeted drug therapies, the Hh pathway inhibitors (HPIs) vismodegib and sonidegib. In the skin, physiological Hh signalling is activated in growing hair follicles (HFs), where it is required for proliferation of the epithelium of HFs during morphogenesis and for their postnatal growth. The effects of HPI treatment leading to the regression of BCC and the development of alopecia underpin the central role of the Hh pathway in BCC formation, as well as hair cycling. Given the fact that BCC is a follicular-driven tumour, it is a fine tuning of events that regulate hair cycling that may drive towards the formation of benign follicular hamartomas or malignant BCC neoplasms. Wnt/β-catenin signalling interacts with the Hh signalling during HF morphogenesis, normal hair cycling and BCC development. The aim of this review is to present how key molecular events implicated in Hh pathway crosstalk in the HF are also involved in BCC pathogenesis and result in the alopecia developed by HPI treatment.

Abstract
The third-generation aromatase inhibitors (AIs), anastrozole, letrozole and exemestane, are highly effective for the treatment of estrogen receptor-positive breast cancer in postmenopausal women. AIs inhibit the aromatase (CYP19A1)-mediated production of estrogens. Most patients taking AIs achieve undetectable blood estrogen concentrations resulting in drug efficacy with tolerable side effects. However, some patients have suboptimal outcomes, which may be due, in part, to inherited germline genetic variants. This review summarizes published germline genetic associations with AI treatment outcomes including systemic AI concentrations, estrogenic response to AIs, AI treatment efficacy and AI treatment toxicities. Significant associations are highlighted with commentary about prioritization for future validation to identify pharmacogenetic predictors of AI treatment outcomes that can be used to inform personalized treatment decisions in patients with estrogen receptor-positive breast cancer.

Abstract
PURPOSE In the adjuvant setting, specific adverse events (AEs) such as vasomotor symptoms (VMS) and musculoskeletal AEs are associated with relapse-free survival in aromatase inhibitor (AI)-treated patients. In the neoadjuvant setting, specific AEs may be associated with tumor response to AIs as well. METHODS Between 2007 and 2012, 107 patients participated in the prospective TEAMIIA trial, a prospective, phase II trial investigating 6 months of neoadjuvant exemestane in patients with strongly ER-positive breast cancer. Radiological response (≥30% decrease in tumor size) was studied in relation to VMSs and MSAEs. Pearson's Chi-Square tests and multivariate logistic regression analyses were used to evaluate of statistical significance (p < 0.05). RESULTS Out of 102 patients 26 patients (25.4%) experienced at least one episode of VMS and 27 patients (26.4%) experienced MSAE. Out of 240 reported adverse events, 71 were specific AEs (40 MSAEs, 31 VMSs). Radiological response was greater in patients who reported VMSs compared to patients who did not (70.8% vs. 49.3%, multivariate OR 2.91, 95% C.I. 1.03-8.26, P = 0.045). No significant advantage towards better response was observed in patients who experienced MSAEs (60.0% vs. 53.3%, univariate OR 1.33, 95% C.I. 0.53-3.38, P = 0.545). CONCLUSION VMSs are associated with tumor response to neoadjuvant exemestane and may be useful for predicting treatment outcomes of AI treatment at an early stage in patients treated with neoadjuvant AIs.

Abstract
Background Single nucleotide polymorphisms (SNPs) in the estrogen receptor 1 (ESR1) and cytochrome P450 19A1 (CYP19A1) genes have been associated with breast cancer risk, endocrine therapy response and side effects, mainly in postmenopausal women with early breast cancer. This analysis aimed to assess the association of selected germline CYP19A1 and ESR1 SNPs with early-onset hot flashes, sweating and musculoskeletal symptoms in premenopausal patients enrolled in the Tamoxifen and Exemestane Trial (TEXT). Methods Blood was collected from consenting premenopausal women with hormone-responsive early breast cancer, randomly assigned to 5-years of tamoxifen plus ovarian suppression (OFS) or exemestane plus OFS. DNA was extracted with QIAamp kits and genotyped for two CYP19A1 (rs4646 and rs10046) and three ESR1 (rs2077647, rs2234693 and rs9340799) SNPs by a real-time pyrosequencing technique. Adverse events (AEs) were recorded at baseline and 3-monthly during the first year. Associations of the genotype variants with grade ≥2 early-onset targeted AEs of hot flashes/sweating or musculoskeletal events were assessed using logistic regression models. Results There were 2660 premenopausal patients with breast cancer in the intention-to-treat population of TEXT, and 1967 (74 %) are included in this translational study. The CYP19A1 rs10046 variant T/T, represented in 23 % of women, was associated with a reduced incidence of grade ≥2 hot flashes/sweating (univariate odds ratio (OR) = 0.78; 95 % CI 0.63–0.97; P = 0.03), more strongly in patients assigned exemestane + OFS (TT vs CT/CC: OR = 0.65, 95 % CI = 0.48–0.89) than assigned tamoxifen + OFS (OR = 0.94, 95 % CI = 0.69–1.27, interaction P = 0.03). No association with any of the CYP19A1/ESR1 genotypes and musculoskeletal AEs was found. Conclusion The CYP19A1 rs10046 variant T/T favors lower incidence of hot flashes/sweating under exemestane + OFS treatment, suggesting endocrine-mediated effects. Based on findings from others, this SNP may potentially enhance treatment adherence and treatment efficacy. We plan to evaluate the clinical impact of this polymorphism during time, pending sufficient median follow up. Trial registration ClinicalTrials.gov NCT00066703, registered August 6, 2003.

Body mass index and menopausal disorders during menopause affect vasomotor symptoms of postmenopausal Japanese breast cancer patients treated with anastrozole: a prospective multicenter cohort study of patient-reported outcomes. Breast Cancer 2016; 24:528-534.

Abstract
BACKGROUND Adverse events related to endocrine therapies have a major impact not only on patients' quality of life but also on treatment discontinuation. Although vasomotor symptoms induced by aromatase inhibitors are frequently recognized, risk factors, especially for Japanese women, are not well reported. To identify risk factors for vasomotor symptoms of Japanese breast cancer patients treated with adjuvant anastrozole, we conducted a prospective cohort study based on patient-reported outcomes (PROs). PATIENTS AND METHODS For this prospective cohort study (SAVS-JP, UMIN000002455), 391 postmenopausal Japanese estrogen receptor-positive breast cancer patients who were treated with adjuvant anastrozole were recruited from 28 centers. The PRO assessment was obtained from a self-reported questionnaire at baseline, 3, 6, 9 and 12 months between August 2009 and April 2012. Vasomotor symptoms, comprising hot flashes, night sweats, and cold sweats, were categorized into four grades (none, Grade 1: mild, Grade 2: moderate, Grade 3: severe). Pre-existing symptoms were only included if they had become worse than at baseline. RESULTS Hot flashes, night sweats, and cold sweats at baseline were reported by 20.5, 15.1, and 8.2 % of the patients, respectively, and new appearance or worsening of symptoms in comparison with baseline by 38.4, 29.3, and 28.7 %, respectively. About 80 % of newly occurring symptoms were Grade 1, and less than 5 % were Grade 3. Vasomotor symptoms were reported by 201 out of 362 patients (55.5 %) during the first year and the mean time to onset was 5.6 months. Patients with vasomotor symptoms were significantly younger (mean 62.8 years, range 38-86 vs 64.7 years, range 37-84; p = 0.02), had higher body mass index (BMI) (23.4 kg/m2, range 15.8-39.9 vs 22.4 kg/m2, range 15.8-34.9; p = 0.01), had vasomotor symptoms sooner after menopause (12.4 years, range 0-51 vs 15.1 years, range 1-37; p = 0.002), and had more menopausal disorders during menopause (63.3 vs 36.7 %; p = 0.002). Multivariate analysis showed that BMI [odds ratio (OR) 1.09 per unit of increase, 95 % confidence interval (CI) 1.02-1.16; p = 0.009] and experiencing menopausal disorders (OR 2.11, 95 % CI 1.35-3.30; p = 0.001) were significantly associated with vasomotor symptoms. CONCLUSION High BMI and experiencing menopausal disorders at menopause were found to be significantly associated with the occurrence of vasomotor symptoms. These findings are expected to prove useful for the management of postmenopausal Japanese women treated with aromatase inhibitors.

Abstract
PURPOSE/OBJECTIVES To describe the experience of women with estrogen receptor-positive breast cancer who are initiating oral adjuvant therapy and to determine what they describe as facilitating and/or hindering this experience.
. RESEARCH APPROACH Qualitative inquiry.
. SETTING Massachusetts General Hospital Cancer Center in Boston.
. PARTICIPANTS 14 women aged 48-81 years.
. METHODOLOGIC APPROACH Qualitative, descriptive study using content analysis.
. FINDINGS Five themes were identified. CONCLUSIONS Each participant who was initiating oral adjuvant treatment described many unmet needs. Women who were caregivers, were older aged, had several chronic illnesses, and were on several medications reported more difficulty transitioning to oral adjuvant therapy.
. INTERPRETATION This study suggests that nurses need to collaborate with other members of the healthcare team to assess the needs of and provide comprehensive care to women initiating oral adjuvant therapy. This is particularly true for women who are older aged, self-reported caregivers, and on several medications, and who have chronic comorbid conditions.

Abstract
PURPOSE New onset symptoms on adjuvant aromatase inhibitors for hormone receptor positive early breast cancer may associate with clinical outcomes. We performed this exploratory analysis of the association of new onset musculoskeletal (MSK) and vasomotor (VM) symptoms with clinical outcomes in the NCIC CTG MA.17 trial 5 years of extended adjuvant endocrine therapy with letrozole after tamoxifen. METHODS Symptoms were collected at baseline, 1, 6, and every 12 months on study. Multivariate Cox Models adjusting for age, nodal status, duration of tamoxifen and prior chemotherapy were used to compare disease-free survival (DFS), distant disease-free survival (DDFS), and overall survival (OS) based on data collected before, and after, the unblinding between women with VM or MSK symptoms and those without. RESULTS Data post-unblinding showed new VM symptoms on extended letrozole significantly improved DFS and DDFS when occurring 1 month (DFS HR 0.52, 95% CI, 0.28-0.96; p = 0.04; DDFS HR 0.49, 95% CI, 0.24-0.99; p = 0.046) and 6 months (DFS HR 0.43, 95% CI, 0.24-0.78; p = 0.006; DDFS HR 0.44, 95% CI, 0.22-0.85; p = 0.02) after treatment initiation. Those with new VM symptoms at 12 months also had a significantly better DFS (HR 0.47, 95% CI 0.26, 0.84; P = 0.01) and a trend in improved DDFS. Only a trend to improved OS was found for those with VM symptoms 6 month after treatment. No significant improvement was found for those with new MSK symptoms at any time point or for any endpoint. CONCLUSIONS New onset VM symptoms with extended letrozole may be useful in predicting treatment benefit.

Abstract
PURPOSE Endoxifen is the major mediator of tamoxifen effect and endoxifen levels <15 nmol/L may be associated with increased risk of breast cancer recurrence. We increased tamoxifen dose in breast cancer patients with low endoxifen levels and assessed the influence of various parameters on reaching 15 nmol/L and 30 nmol/L endoxifen levels. EXPERIMENTAL DESIGN Tamoxifen dose was increased in those with endoxifen levels below 30 nmol/L. Toxicity, including hot flash score, was measured. CYP2D6 metabolizer status was classified as ultra-rapid (UM), extensive (EM), intermediate (IM), or poor (PM) based genotype of somatic DNA. RESULTS Dosage was escalated in 68 of 122 participants. On 20 mg tamoxifen, 24% had endoxifen levels below 15 nmol/L and this reduced to 6% following dose escalation. In over 50% of cases, there was no identified cause for low endoxifen. Low baseline endoxifen level, and not CYP2D6 metabolizer status, independently predicted reaching threshold targets for both the 15 nmol/L and 30 nmol/L targets (P = 0.04 and 0.003 respectively). The 15 nmol/L target was reached in all UM/EM and IM patients, 63% of PM patients, and 58% of those with baseline endoxifen of <10 nmol/L. There was no correlation between hot flash score and genotype or any tamoxifen metabolite level including endoxifen (R = 0.07). CONCLUSIONS Low endoxifen on standard dose tamoxifen was the only independent predictor of failure to achieve potentially therapeutic levels. Trials examining tamoxifen dose escalation and breast cancer outcome should be guided by endoxifen levels alone, without reference to CYP2D6 genotype or presence of hot flashes.

Abstract
BACKGROUND Aromatase inhibitor induced musculoskeletal syndrome is experienced by approximately half of women taking aromatase inhibitors, impairing quality of life and leading some to discontinue treatment. Evidence for effective treatments is lacking. We aimed to understand the manifestations and impact of this syndrome in the Australian breast cancer community, and strategies used for its management. METHODS A survey invitation was sent to 2390 members of the Breast Cancer Network Australia Review and Survey Group in April 2014. The online questionnaire included 45 questions covering demographics, aromatase inhibitor use, clinical manifestations and risk factors for the aromatase inhibitor musculoskeletal syndrome, reasons for treatment discontinuation and efficacy of interventions used. RESULTS Aromatase inhibitor induced musculoskeletal syndrome was reported by 302 (82 %) of 370 respondents. Twenty-seven percent had discontinued treatment for any reason and of these, 68 % discontinued because of the musculoskeletal syndrome. Eighty-one percent had used at least one intervention from the following three categories to manage the syndrome: doctor prescribed medications, over-the-counter/complementary medicines or alternative/non-drug therapies. Anti-inflammatories, paracetamol (acetaminophen) and yoga were most successful in relieving symptoms in each of the respective categories. Almost a third of respondents reported that one or more interventions helped prevent aromatase inhibitor discontinuation. However, approximately 20 % of respondents found no intervention effective in any category. CONCLUSION We conclude that aromatase inhibitor induced musculoskeletal syndrome is a significant issue for Australian women and is an important reason for treatment discontinuation. Women use a variety of interventions to manage this syndrome; however, their efficacy appears limited.

Abstract
INTRODUCTION Aromatase inhibitor (AI) therapy is the current preferred choice of endocrine therapy in postmenopausal estrogen receptor-positive breast cancer patients thanks to their improved effectiveness compared to tamoxifen. Despite the absence of increased endometrial pathology and deep venous thrombosis seen in tamoxifen-users, the safety profile of AIs consists of a variety of bothersome side effects negatively influencing daily functioning. AREAS COVERED Besides the well-known adverse effects on joints and bone and the vasomotor system, more neglected and latent toxicity like cognitive problems and vulvovaginal atrophy will be discussed. Concern has been raised in terms of increased risk of fractures and cardiovascular events with chronic AI use. EXPERT OPINION Placebo-controlled long-term studies carefully monitoring these adverse events, together with more extensive research in the etiologies, are warranted.

Abstract
PURPOSE To identify predictors of discontinuation of adjuvant hormone therapy in patients with breast cancer. PATIENTS AND METHODS We conducted a record-linkage study based on data from Stockholm-Gotland Breast Cancer Register, Swedish Prescribed Drug Register, and self-reported questionnaire. Women diagnosed with breast cancer between 2005 and 2008 in Stockholm, Sweden, were prospectively followed for 5 years until 2013, starting from their first prescription of tamoxifen or aromatase inhibitors (N = 3,395). RESULTS Family history of ovarian cancer (hazard ratio [HR], 1.55; 95% CI, 1.19 to 2.02); younger (< 40 years; HR, 1.39; 95% CI, 1.08 to 1.78) and older (≥ 65 years; HR, 1.15; 95% CI, 1.03 to 1.28) age; higher Charlson comorbidity index (≥ 2 v 0; HR, 1.35; 95% CI, 1.03 to 1.76); and use of analgesics (HR, 1.33; 95% CI, 1.16 to 1.52), hypnotics/sedatives (HR, 1.24; 95% CI, 1.07 to 1.43), GI drugs (HR, 1.25; 95% CI, 1.08 to 1.43), and hormone replacement therapy (HR, 1.27; 95% CI, 1.08 to 1.49) were identified as baseline predictors for hormonal treatment discontinuation. Use of analgesics (HR, 1.22; 95% CI, 1.08 to 1.37), hypnotics/sedatives (HR, 1.21; 95% CI, 1.07 to 1.37), antidepressants (HR, 1.22; 95% CI, 1.06 to 1.40), or GI drugs (HR, 1.27; 95% CI, 1.13 to 1.43), and switching therapy between tamoxifen and aromatase inhibitors (HR, 1.50; 95% CI, 1.23 to 1.83) during the first year of hormonal treatment were associated with increased risk of discontinuation during the next 4 years. CONCLUSION Predictors identified in our study can be used in developing targeted intervention to prevent adjuvant hormone therapy discontinuation and subsequently to improve breast cancer outcomes.

Abstract
BACKGROUND/AIMS Adjuvant endocrine therapy for at least 5 years improves oncological outcomes in oestrogen receptor-positive breast cancer. Adherence rates to prescribed endocrine therapy are low and the search for modifiable causes of this continues. The aim of this study was to assess adherence rates in an Irish cohort of breast cancer patients prescribed adjuvant endocrine therapy and to assess modifiable factors associated with suboptimal adherence. METHODS A cross-sectional anonymous survey was performed on 261 patients currently prescribed endocrine therapy. Data were collected regarding demographics, treatment, social and emotional factors and medication side effects. Each patient completed a medication adherence score and provided information about discontinuation of therapy and reasons for same. RESULTS Only 67.8 % of patients assessed demonstrated complete medication adherence on the medication adherence scale. Twenty-nine patients (10.9 %) permanently stopped taking their prescribed endocrine therapy. Suboptimal adherence was more likely in younger patients (p < 0.001), those in employment (p = 0.005), those who experienced side effects (p = 0.006), those who perceived themselves to have low levels of emotional support (p < 0.001) and those who use the internet to read about their illness (p = 0.003). CONCLUSIONS Endocrine therapy adherence is suboptimal in almost one-third of patients in our cohort. Appropriate assessment and management of side effects and negative emotions, combined with direction of patients to accurate internet sources of information, could help improve endocrine therapy adherence in women with early-stage breast cancer.
