Acupuncture for hot flashes in hormone receptor-positive breast cancer: A pooled analysis of individual patient data from parallel randomized trials. Cancer 2024. [PMID: 38924035 DOI: 10.1002/cncr.35374] [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: 11/04/2023] [Revised: 04/10/2024] [Accepted: 04/15/2024] [Indexed: 06/28/2024]
Abstract
BACKGROUND Hot flashes are a common side effect of endocrine therapy (ET) that contribute to poor quality of life and decreased treatment adherence. METHODS Patients with breast cancer wo were receiving ET and experiencing hot flashes were enrolled through three parallel, randomized trials conducted in the United States, China, and South Korea. Participants were randomized to either immediate acupuncture (IA) or delayed acupuncture control (DAC). IA participants received 20 acupuncture sessions over 10 weeks, whereas DAC participants received usual care, then crossed over to acupuncture with a reduced intensity. The primary end point was a change in score on the endocrine symptom subscale of the Functional Assessment of Cancer Therapy (FACT)-Endocrine Symptoms between baseline and week 10. Secondary end points included the hot flash score and the FACT-Breast score. A planned pooled analysis of individual patient data was performed using longitudinal mixed models. RESULTS In total, 158 women with stage 0-III breast cancer were randomized (United States, n = 78; China, n = 40; South Korea, n = 40). At week 10, IA participants reported statistically significant improvements in the endocrine symptom subscale score (mean change ± standard error: 5.1 ± 0.9 vs. 0.2 ± 1.0; p = .0003), the hot flash score (-5.3 ± 0.9 vs. -1.4 ± 0.9; p < .003), and the FACT-Breast total score (8.0 ± 1.6 vs. -0.01 ± 1.6; p = .0005) compared with DAC participants. The effect of the acupuncture intervention differed by site (p = .005). CONCLUSIONS Acupuncture led to statistically and clinically meaningful improvements in hot flashes, endocrine symptoms, and breast cancer-specific quality of life in women undergoing ET for breast cancer in the United States, China, and South Korea.

J Cancer Surviv 2024:10.1007/s11764-024-01553-y. [PMID: 38383907 DOI: 10.1007/s11764-024-01553-y] [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: 01/11/2024] [Accepted: 02/13/2024] [Indexed: 02/23/2024]
Abstract
PURPOSE In 2020, almost 9 million women were diagnosed with cancer worldwide. Despite advancements in cancer treatment strategies, patients still suffer from acute and long-term side effects. This systematic review aims to evaluate the most frequently reported adverse effects in the genitourinary system and compare them across cancer types, treatment modalities, and evaluation methods. METHODS Pubmed Central, SCOPUS, and Cochrane Library were searched following the PRISMA guidelines to identify all prospective and retrospective observational cohort studies and randomized controlled trials assessing vaginal side effects of adult female cancer patients. The study quality was evaluated using The Newcastle-Ottawa Scale or the Risk of Bias 2 tool, as appropriate. RESULTS The most prevalent population was breast cancer patients, followed by gynaecological cancer patients. Overall, the focus was on vaginal dryness, while vaginal stenosis was the primary outcome in gynaecological cancer patients. Significant discrepancies were found in the frequency and severity of the reported adverse events. Most studies in this review evaluated side effects using patient-reported outcome measures (PROMs). CONCLUSIONS Genitourinary syndrome of menopause following cancer treatment is most frequently documented in breast and gynaecological cancer patients, often focussing on vaginal dryness and vaginal stenosis based on PROMs. This review provides a complete overview of the literature, but more high-quality clinical trials are necessary to draw firm conclusions on acute and chronic vaginal toxicity following cancer treatment. IMPLICATIONS FOR CANCER SURVIVORS This review could help improve the current preventive and curative management options for genitourinary complications, thereby increasing the patient's QoL and sexual functioning.

Abstract
BACKGROUND Sexual well-being is a key determinant of quality of life. Sexual dysfunction in patients with metastatic breast cancer (MBC) is understudied. PATIENTS AND METHODS Patients were eligible for this study if they participated in the Mayo Clinic Breast Disease Registry (MCBDR), had a diagnosis of de novo MBC, and responded to a question about sexual dysfunction at the baseline MCBDR survey. Participants reported their sexual dysfunction on a scale of 0 (no dysfunction) to 10 (severe dysfunction) at baseline and then annually for 4 years. Participants answered additional sexual symptom questions in years 2 and 4. Associations between patient attributes and the presence and severity of sexual dysfunction, changes in sexual dysfunction from baseline to subsequent surveys, and associations between specific sexual symptoms and severity of sexual dysfunction were assessed. RESULTS One hundred three patients with de novo MBC answered the sexual dysfunction question at baseline. The prevalence of any sexual dysfunction (score of 1-10) was 56.3% at baseline (n = 103), 57.1 % at year 1 (n = 77), 80.4% at year 2 (n = 46), 65.8% at year 3 (n = 38), and 85% at year 4 (n = 20). Vaginal dryness was reported by approximately 49% and 39% of patients in years 2 and 4 respectively. Vaginal dryness was associated with higher severity of sexual dysfunction. CONCLUSIONS Self-reported sexual dysfunction is frequent in women with de novo MBC. Vaginal dryness is a frequently reported treatable symptom associated with higher severity of sexual dysfunction. Clinicians should assess patients with MBC for sexual dysfunction and discuss potential treatment strategies.

Abstract
OBJECTIVE In this article, the quality of life (QOL) of Spanish postmenopausal early-stage breast cancer patients who have finished endocrine therapy (ET), QOL changes after endocrine therapy cessation, and the differences between two endocrine therapy modalities (tamoxifen or aromatase inhibitor [AI]) are studied. More QOL information after endocrine therapy cessation is needed. METHODS A prospective cohort study was performed. Participating in the study were 158 postmenopausal patients who had received tamoxifen or AI for 5 years. In some cases, endocrine therapy may have changed during those 5 years.Patients completed the European Organisation for Research and Treatment of Cancer QLQ-C30 and QLQ-BR45 questionnaires at baseline, after 6 months, and after 1 year of follow-up. Patients older than 65 years also completed the QLQ-ELD14. Linear mixed-effect models were used to evaluate longitudinal changes in QOL and differences in QOL between endocrine therapy modalities. RESULTS QOL scores for the whole sample throughout follow-up were high (>80/100 points) in most QOL areas. Moderate limitations (>30 points) occurred in the QLQ-BR45 in sexual functioning and sexual enjoyment, future perspective, and joint symptoms. Moderate limitations also occurred in the QLQ-ELD14 in worries about others, maintaining purpose, joint stiffness, future worries, and family support. In those who had finished endocrine therapy, pain was reduced in all three assessments conducted during the 1-year follow-up period in both groups. Tamoxifen patients showed better QOL in functioning (role functioning, global QOL, financial impact), symptoms (pain), and emotional areas (future perspective and worries about others) than AI patients but worse QOL in skin mucosis symptoms. CONCLUSIONS The results of this study show that postmenopausal early-stage breast cancer patients adapted well to their disease and endocrine therapy treatment. QOL improvements in the 1-year follow-up period appeared in one key area: pain. Differences between endocrine therapy modalities suggested QOL was better in the tamoxifen group than in the AI group.

Abstract
PURPOSE The safety of local estrogen therapy in patients on adjuvant endocrine treatment is questioned, but evidence on the issue is scarce. This nested case-control registry-based study aimed to investigate whether estrogen therapy affects breast cancer mortality risk in women on adjuvant endocrine treatment. METHODS In a cohort of 15,198 women diagnosed with early hormone receptor (HR)-positive breast cancer and adjuvant endocrine treatment, 1262 women died due to breast cancer and were identified as cases. Each case was matched with 10 controls. Exposure to estrogen therapy with concurrent use of aromatase inhibitors (AIs), tamoxifen, or both sequentially, was compared between cases and controls. RESULTS No statistically significant difference in breast cancer mortality risk was seen in patients with exposure to estrogen therapy concurrent to endocrine treatment, neither in short-term or in long-term estrogen therapy use. CONCLUSIONS The study strengthens current evidence on local estrogen therapy use in breast cancer survivors, showing no increased risk for breast cancer mortality in patients on adjuvant AIs or tamoxifen.

Abstract
BACKGROUND Adjuvant endocrine therapy (AET) reduces breast cancer recurrence and mortality of women with hormone-receptor-positive tumors, but poor adherence remains a significant problem. The aim of this study was to analyze AET side effects and their impact on adherence to treatment. METHODS A total of 373 breast cancer patients treated with AET filled out a specific questionnaire during their follow up visits at the Breast Unit of our Centre. RESULTS Side effects were reported by 81% of patients, 84% of those taking tamoxifen and 80% of those taking aromatase inhibitors (AIs). The most common side effect in the tamoxifen group was hot flashes (55.6%), while in the AI group it was arthralgia (60.6%). The addition of GnRH agonists to both tamoxifen and AI significantly worsened all menopausal symptoms. Overall, 12% of patients definitively discontinued AET due to side effects, 6.4% during the first 5 years and 24% during extended therapy. Patients who had previously received chemotherapy or radiotherapy reported a significantly lower discontinuation rate. CONCLUSIONS AET side effects represent a significant problem in breast cancer survivors leading to irregular assumption and discontinuation of therapy. Adherence to AET may be improved by trustful patient-physician communication and a good-quality care network.

Abstract
BACKGROUND Acupuncture has been reported to reduce hot flashes in patients with breast cancer undergoing adjuvant hormonal therapy. Although hot flashes are common, the prevalence varies among cultures, races, and ethnicities; the efficacy of acupuncture across cultures has not been investigated. METHODS This is a coordinated multinational study, including three parallel randomized trials with a planned analysis of individual patient data, to test the effectiveness of acupuncture on hot flash-related symptoms in hormone receptor-positive breast cancer patients on adjuvant endocrine therapy. Using a standardized acupuncture protocol (total across all three studies of n = 80) versus usual care (total n = 80), symptoms are assessed using changes in the Endocrine Symptom Subscale of Functional Assessment of Cancer Therapy-Endocrine Symptoms. Secondary outcomes include hot flash severity, quality of life, and sleep quality. Differences in response to acupuncture between participants in the three countries will also be explored. DISCUSSION Here we describe the design of a protocol for a coordinated multinational study, with attention to the complex considerations in developing a multinational research effort testing a non-pharmacologic intervention. This protocol and approach provide guidance for future efforts to evaluate and test non-pharmacologic interventions across multinational populations.

Abstract
Purpose This study aimed to explore symptom trajectories over 24 months for hot flushes and sweating, sleep problems, joint and muscular discomfort, and physical and mental exhaustion experienced by premenopausal women diagnosed with tamoxifen-treated breast cancer. Methods A total of 104 patients participated in the study. The menopausal symptoms were examined using the Menopausal Rating Scale at baseline, 3–6, 12, and 18–24 months after initiating tamoxifen. The changes over four time points were analyzed using repeated measures analysis of variance. The chi-square test was used to examine the differences between “no symptom-to-mild” and “moderate-to-extremely severe” 3–6 months after initiating tamoxifen according to the patients’ chemotherapy treatment experiences. Results All menopausal symptoms occurred in > 70% of patients with breast cancer and persisted until 24 months. More than 50% of patients experienced four menopausal symptoms, with at least two at a serious severity level after initiating tamoxifen. Hot flushes and sweating occurred in the highest number of patients, recording high scores. Sleep problems and physical and mental exhaustion exhibited relatively high scores, even before tamoxifen initiation. There were significant changes over four time points in all symptoms. Young patients aged < 40 years experienced more severe sleep problems, and patients who had previously received chemotherapy experienced more severe joint and muscular discomfort. Conclusions This study’s findings may assist in alerting healthcare providers to menopausal symptoms that develop during tamoxifen therapy and the need for early and active intervention to minimize symptom occurrence and distress.

Abstract
The global incidence of breast cancer is increasing, as is the efficacy of treatments. Consequently, increasing survival rates reinforce the importance of survivorship issues, including posttreatment menopausal symptoms, sexual function, and mental health and well-being. Breast cancer patients can experience a range of menopausal symptoms associated with their treatment. Most commonly women may experience vasomotor symptoms, including hot flushes and night sweats. Particularly for women on maintenance tamoxifen therapy, up to 80% will experience hot flushes, with almost one-third of these women reporting severe symptoms. Breast cancer patients may also experience genitourinary symptoms of menopause, which may include vaginal dryness and irritation, dyspareunia, and dysuria. Hormonal therapy has long been established as the most effective treatment for vasomotor symptoms. However, the hormonal nature of breast malignancies renders systemic hormone therapies unsuitable for these patients, posing a unique treatment challenge, which may result in clinicians not feeling confident to manage them. Consequently, this review outlines pharmacological and nonpharmacological options for women with bothersome menopausal symptoms after breast cancer treatment and provides practical, evidence-based guidance for clinicians.

Abstract
The majority of breast cancers are diagnosed at an early stage and are hormone receptor (HR)-positive and human epidermal growth factor receptor 2 (HER2)-negative. Significant advances have been made in the management of early stage HR-positive, HER2-negative breast cancer, resulting in improved survival outcomes. In this review, we discuss important factors to consider in the management of this disease. In particular, we discuss the role of adjuvant endocrine therapy, specific endocrine therapy agents, the duration of adjuvant endocrine therapy, treatment-related side effects, and the role of genomic assays and other biomarkers when considering treatment recommendations for individuals with HR-positive, HER2-negative early breast cancer. Finally, we address emerging data to individualize therapeutic decision-making and provide future considerations.

Abstract
As advances in cancer therapies have improved cancer-related survival, novel therapeutics have also introduced a variety of dermatologic toxicities, and an increased number of patients are living with these sequalae. Women with cancer in particular experience a spectrum of dermatologic conditions that affect their skin, hair, nail, and mucosal surfaces. Studies have shown that these toxic effects can significantly affect quality of life and alter a woman's self-image, cultural identity, femininity, sexuality, and mental health. In severe instances, dermatologic toxicities may even disrupt cancer therapy and can therefore affect overall survival and treatment response. In this article, we review the dermatologic adverse effects from traditional chemotherapy, targeted therapy, immune checkpoint inhibitors, and endocrine therapy that disproportionately affect women. The timely diagnosis and management of these dermatologic conditions is crucial in the multidisciplinary care of women with cancer.

Abstract
Background Patients' compliance and persistence with endocrine treatment has a significant effect on the prognosis in early breast cancer (EBC). The purpose of this analysis was to identify possible reasons for non-persistence, defined as premature cessation of therapy, on the basis of patient and tumor characteristics in individuals receiving adjuvant treatment with letrozole. Patients and methods The EvAluate-TM study is a prospective, multicenter, noninterventional study in which treatment with the aromatase inhibitor letrozole was evaluated in postmenopausal women with hormone receptor-positive EBC in the early therapy phase. Treatment persistence was evaluated at two pre-specified study visits after 6 and 12 months. As a measure of early therapy persistence the time from the start to the end of treatment (TTEOT) was analyzed. Cox regression analyses were carried out to identify patient characteristics and tumor characteristics predicting TTEOT. Results Out of the total population of 3941 patients with EBC, 540 (13.7%) events involving treatment cessation unrelated to disease progression were observed. This was due to drug-related toxicity in the majority of cases (73.5%). Persistence rates were 92.2%, 86.9%, and 86.3% after 6, 12, and 15 months, respectively. The main factors influencing premature treatment discontinuation were older age [hazard ratio (HR) 1.02/year], comorbidities (HR 1.06 per comorbidity), low body mass index, and lower tumor grade (HR 0.85 per grade unit). Conclusion These results support the view that older, multimorbid patients with low tumor grade and low body mass index are at the greatest risk for treatment discontinuation and might benefit from compliance and support programs.

Abstract
PURPOSE In this paper we study the quality of life (QoL) of elderly breast cancer patients receiving endocrine treatment (ET). More QoL data on elderly patients treated with ET are needed. Our aims are to study QoL in early-stage breast cancer patients throughout the treatment period and compare the QoL of ET groups. METHODS 148 patients > 65 years who began ET with either tamoxifen or aromatase inhibitor (AI) completed the EORTC QLQ-C30 and QLQ-BR23 and the Interview for Deterioration in Daily Living Activities in Dementia (IDDD) questionnaires three times over 3 years of ET. Linear mixed-effect models were used to evaluate longitudinal QoL changes. ET group comparisons were conducted after 3 years of treatment via ANCOVA adjusted by basal QoL. RESULTS QoL scores were high (> 80/100 points) in most QoL areas, with moderate limitations (> 30) in sexual functioning and enjoyment and in future perspective. After 3 years of ET, four QoL areas improved (< 6 points) compared to baseline and 3-month assessments. Hot flushes worsened (8 points) at the 3-month assessment but by 3 years had recovered. AI patients showed more hot flushes, pain and diarrhea and less sexual enjoyment than tamoxifen patients after 3 years of ET (differences 3-12 points). CONCLUSIONS Results indicate that elderly early-stage breast cancer patients adapted well to their disease and ET treatment over the 3 years. Few QoL differences were observed between ET groups.

Abstract
Hot flashes (HFs), defined as transient sensations of heat, sweating, flushing, anxiety, and chills lasting for 1-5 min, constitute one of the most common symptoms of menopause among women though only a few seek treatment for these. The basis of HFs lies in abnormal hypothalamic thermoregulatory control resulting in abnormal vasodilatory response to minor elevations of core body temperature. Recent data suggest an important role for calcitonin gene-related peptide, hypothalamic kisspeptin, neurokinin B and dynorphin signal system, serotonin, norepinephrine in causation of HFs in addition to estrogen deficiency which plays a cardinal role. The mainstay of treatment includes hormonal replacement therapy, selective serotonin, and norepinephrine reuptake inhibitors in addition to lifestyle modification. In this review, we address common issues related to menopause HFs and suggest a stepwise approach to their management.

Abstract
INTRODUCTION Menopausal symptoms are frequent and severe in breast cancer survivors taking tamoxifen; however, treatment options are limited for these patients as hormonal replacement therapy is contraindicated. This study aimed to explore the experience and attribution of menopausal symptoms and identify factors related to the experience of menopausal symptoms in women taking tamoxifen. METHODS Women who had been prescribed tamoxifen for a diagnosis of primary breast cancer were recruited from oncology clinics across England and from online advertisements. Seven hundred and forty women completed questionnaires assessing illness perceptions, social support, mood and symptom duration/severity. RESULTS Eighty-four percent of women had experienced hot flushes and 80% experienced night sweats; of these, 60% experienced severe symptoms. Symptoms persisted throughout 5 years of treatment and were mainly attributed to tamoxifen. Logistic regressions showed that depressive symptoms, previous chemotherapy and being employed were associated with increased odds of hot flush or night sweat prevalence. Symptom severity was associated with depression, being employed and attributing symptoms to tamoxifen. DISCUSSION These findings have clinical implications in terms of targeting women who are more at risk and offering non-hormonal treatment options, such as cognitive behavioural therapy, to help women to develop self-management strategies for coping with menopausal symptoms.

Abstract
In the prospective Exemestane and Letrozole Pharmacogenetics trial of adjuvant aromatase inhibitor (AI) therapy for early-stage breast cancer, worsening of multiple treatment-related symptoms during AI therapy predicted AI early discontinuation. If these findings are confirmed in independent trials, early detection of changes in PRO measures could be used clinically to target interventions in patients at high risk for early discontinuation. Background. Early discontinuation of aromatase inhibitors (AIs) is common and leads to poor outcomes but is challenging to predict. In the Exemestane and Letrozole Pharmacogenetics trial, a high rate of early discontinuation due to intolerance was observed. We hypothesized that early changes in patient-reported outcomes (PROs) predict AI discontinuation and that biochemical factors are associated with changes in PROs. Patients and Methods. Postmenopausal women with early-stage breast cancer enrolled in a prospective randomized trial of exemestane versus letrozole completed questionnaires at baseline and serially over 24 months to assess overall quality of life (EuroQOL Visual Analog Scale [VAS]); mood; and multiple symptoms, including a musculoskeletal symptom cluster. A joint mixed-effects/survival model was used to estimate the effect of the change in PROs on AI discontinuation. Associations between biochemical factors and change in PROs were examined. Results. A total of 490 patients were analyzed. Worsening of EuroQOL VAS and the musculoskeletal cluster were associated with the highest risk for early discontinuation (hazard ratio [HR], 2.77 [95% confidence interval (CI), 2.72–2.81; p = .015]; HR, 4.39 [95% CI, 2.40–8.02; p < .0001], respectively). Pharmacokinetics and estrogen metabolism were not consistently associated with change in PRO measures. No clinically significant differences in any PRO between AIs were observed. Conclusion. Changes in PROs early during AI therapy were associated with treatment discontinuation. Identification of these changes could be used to target interventions in patients at high risk for early discontinuation. Implications for Practice: Early changes in patient-reported outcomes (PROs) can predict nonpersistence to aromatase inhibitor therapy. If used in clinical practice, PROs might identify women at highest risk for early discontinuation and allow for interventions to improve tolerance before significant toxicities develop. Further research is needed to improve capturing PROs in routine clinical practice.

Abstract
The goal of this survey-based study was to examine whether aromatase inhibitor (AI) therapy was associated with depressive symptoms and self-rated health among Black and White breast cancer survivors (N = 761). Results showed that among Black, but not White, breast cancer survivors current AI therapy was associated with a significant increase in the odds of both depressive symptoms (OR 3.59; 95% CI 1.01, 13.00) and poorer self-rated health (OR 3.16; 95% CI 1.06, 9.46). Presence of pain was significantly associated with increased odds of both outcomes among both groups. The findings underscore the importance of addressing not only physical but mental health among breast cancer survivors on AIs, especially those of Black race.

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
Breast cancer is the most prevalent cancer in women, causing a significant mortality worldwide. Different endocrine strategies are available for the treatment of hormone-sensitive breast cancer, including antiestrogen tamoxifen and fulvestrant, as well as third-generation aromatase inhibitors (AIs), such as letrozole, anastrozole, and exemestane. In this review, we will focus on exemestane, its clinical use, and its side effects. Exemestane is a steroidal third-generation AI now used in all treatment settings for breast cancer. In the metastatic disease, it has been extensively investigated as the first-, second-, and further-line treatment and it is now registered for the treatment of postmenopausal women with advanced estrogen-receptor-positive breast cancer whose disease has progressed following antiestrogen therapy. A potential lack of cross-resistance with nonsteroidal AIs has been described, giving additional therapeutic opportunities in sequences of endocrine agents. Exemestane is also approved for the adjuvant treatment of postmenopausal early breast cancer, either as upfront monotherapy for 5 years, as a switch following 2–3 years of tamoxifen, or as extended therapy beyond 5 years of adjuvant treatment. New promising data also showed a beneficial effect in young premenopausal early breast cancer patients, when administered together with ovarian suppression. Interesting results have also emerged when exemestane has been investigated as neodjuvant treatment as well as preventive agent in healthy women at high risk for breast cancer. Exemestane is generally well tolerated, with a side effect profile similar to that of other AIs, including menopausal symptoms, arthralgia, and bone loss. In conclusion, exemestane can be considered an effective and well-tolerated endocrine treatment option for all stages of breast cancer.

Abstract
INTRODUCTION Sexual dysfunction has only recently been recognized as a highly prevalent side effect of adjuvant aromatase inhibitor (AI) therapy for breast cancer. AIMS A cross-sectional survey using standardized measures of female sexual function was designed to provide a detailed view of sexual problems during the first 2 years of adjuvant AI therapy and secondarily to examine whether sexual dysfunction leads to nonadherence to this therapy. METHODS Questionnaires were mailed to all 296 women in a breast oncology registry who had been prescribed a first-time AI for localized breast cancer 18-24 months previously. MAIN OUTCOME MEASURES Items assessed medication adherence, demographic, and medical information. Scales included the Female Sexual Function Index, the Menopausal Sexual Interest Questionnaire, the Female Sexual Distress Scale-Revised, the Breast Cancer Prevention Trial Eight Symptom Scale to assess menopausal symptoms, and the Merck Adherence Estimator(®) . RESULTS Questionnaires were returned by 129 of 296 eligible women (43.6%). Respondents were 81% non-Hispanic white with a mean age of 63 and 48% had at least a college degree. Only 15.5% were nonadherent. Ninety-three percent of women scored as dysfunctional on the Female Sexual Function Index, and 75% of dysfunctional women were distressed about sexual problems. Although only 52% of women were sexually active when starting their AI, 79% of this group developed a new sexual problem. Fifty-two percent took action to resolve it, including 24% who stopped partner sex, 13% who changed hormone therapies, and 6% who began a vaginal estrogen. Scores on the Adherence Estimator (beliefs about efficacy, value, and cost of medication) were significantly associated with adherence (P = 0.0301) but sexual function was not. CONCLUSIONS The great majority of women taking AIs have sexual dysfunction that is distressing and difficult to resolve. Most continue their AI therapy, but a large minority cease sexual activity.

Abstract
Breast cancer is the most prevalent type of cancer in women and responsible for significant female cancer-related mortality worldwide. In the Western world, over 80% of breast cancers are hormone-receptor positive for which endocrine therapy is administered. The main anti-estrogen treatments in use consist of selective estrogen-receptor modulators, such as tamoxifen, and third-generation aromatase inhibitors (AIs), such as exemestane, letrozole, and anastrozole. In this review, the focus will lie on exemestane, its clinical use, and its side-effect profile. Exemestane is the only third-generation steroidal AI. Its efficacy as a first-line treatment in metastatic breast cancer has been demonstrated. Therefore, exemestane could be considered a valid first-line therapeutic option, but it also can be used in second-line or further situations. Exemestane is mostly used as part of sequential adjuvant treatment following tamoxifen, but in this setting it is also active in monotherapy. Furthermore, this AI has been studied in the neoadjuvant setting as presurgical treatment, and even as chemoprevention in high-risk healthy postmenopausal women. It may reverse side effects of tamoxifen, such as endometrial changes and thromboembolic disease but may also cause some inconvenient side effects itself. Additionally, there is a lack of total cross-resistance between exemestane and nonsteroidal AIs as far as their anti-tumoral efficacy is concerned; moreover the two classes of AIs display a nontotal overlapping toxicity profile. Taking together, exemestane can be considered as a useful treatment option at all stages of breast cancer.

Abstract
On account of the good prognosis for patients with breast cancer, improving or maintaining the quality of life in the aftercare period is becoming more and more important. In particular, the increasing usage of aromatase inhibitors in the past few years has led to an increased incidence of vaginal atrophy with symptoms such as vaginal dryness, petechial bleeding, dyspareunia and recurrent cystitis. And just these symptoms have a detrimental impact on the quality of life of breast cancer patients. Application of a topical estrogen therapy represents the most effective means to treat vaginal atrophy. The use of a systemic or, respectively, topical hormone therapy is, however, contraindicated for breast cancer patients. Further clinical trials are needed in order to assess the safety of vaginal estrogen therapy.

Abstract
Survivors of breast cancer are confronted with a plethora of cancer treatment-related long-term symptoms, the most common being fatigue, hot flashes, sexual dysfunction, arthralgias, neuropathy, and cognitive dysfunction. Survivors of breast cancer also face cancer treatment-related disease states, such as osteoporosis, cardiac dysfunction, obesity, infertility, and secondary cancers. Evidence-based recommendations for screening, prevention, and early intervention should be implemented to improve quality of life and decrease comorbidities in this population.

Abstract
Exemestane, a steroidal aromatase inhibitor, is licensed for postmenopausal patients with estrogen receptor (ER)-positive breast cancer as second-line therapy in metastatic disease following antiestrogen failure and as part of sequential adjuvant therapy following initial tamoxifen. This study is a systematic literature review, evaluating exemestane in different clinical settings. The Ovid Medline (1948-2012), Embase (1980-2012), and Web of Science (1899-2012) databases were searched. Forty-two relevant articles covering randomized controlled trials were reviewed for efficacy and safety, and three for adherence. With regard to efficacy in metastatic disease, exemestane is superior to megestrol acetate after progression on tamoxifen. There is evidence for noninferiority to fulvestrant (following a prior aromatase inhibitor) and to nonsteroidal aromatase inhibitors in the first-line setting. Combined use with everolimus is shown to be more efficacious than exemestane alone following previous aromatase inhibitor use. In the adjuvant setting, a switch to exemestane after 2-3 years of tamoxifen is superior to 5 years of tamoxifen. Exemestane is noninferior to 5 years of tamoxifen as upfront therapy, and may have a role as an extended adjuvant therapy. Used as neoadjuvant therapy, increased breast conservation is achievable. As chemoprevention, exemestane significantly reduces the incidence of breast cancer in "at-risk" postmenopausal women. Exemestane is associated with myalgias and arthralgias, as well as reduced bone mineral density and increased risk of fracture, which do not appear to persist at follow-up, with subsequent return to pretreatment values. Compared with tamoxifen, there is a reduced incidence of endometrial changes, thromboembolic events, and hot flashes. Limited evidence shows nonadherence in 23%-32% of patients. Evidence is growing in support of exemestane in all clinical settings. It is generally more efficacious and has a better safety profile than tamoxifen. How it compares with the nonsteroidal aromatase inhibitors remains to be established. Further studies are required on adherence to ensure that maximum benefit is obtained.

Abstract
BACKGROUND Approximately 20% to 50% of women diagnosed with hormone receptor-positive breast cancer discontinue endocrine therapy early; most reports come from automated pharmacy data or small self-report evaluations. We conducted a larger self-report evaluation of endocrine therapy discontinuation associated with patient characteristics and therapy-related adverse effects. METHODS We surveyed 538 women from a single health plan who were diagnosed with early-stage breast cancer from 2002 to 2008 and received endocrine therapy. Women reported adverse effects and reasons for discontinuation via mailed survey; tumor characteristics were obtained via registry linkage. We classified women as discontinuers if they self-reported stopping therapy and their self-reported duration of tamoxifen plus aromatase inhibitor (AI) use was < 5 years, and nondiscontinuers if they self-reported ≥ 5 years use or current use. We estimated odds ratios (ORs) with 95% CIs for discontinuation versus continuation by using logistic regression adjusted for age and year of diagnosis. RESULTS Among 538 women, 98 (18.2%) discontinued endocrine therapy early. Women with positive lymph nodes (v negative) were significantly less likely to discontinue therapy (odds ratio [OR] = 0.54; 95% CI, 0.31 to 0.93). Almost all women (94%) experienced adverse effects. Experiencing headaches was associated with discontinuation of AIs (OR = 4.16; 95% CI, 2.16 to 8.01) and tamoxifen (OR = 2.34; 95% CI, 1.24 to 4.41); few other individual adverse effects were related to discontinuation despite most discontinuers reporting they "did not like adverse effects" (AIs: 66.7%, tamoxifen: 59.1%). CONCLUSION Few individual adverse effects or patient characteristics were significantly associated with endocrine therapy discontinuation, yet adverse effects were prevalent and were the most common reason women reported for discontinuing therapy.

Abstract
Aromatase inhibitors (AIs) are recommended as adjuvant endocrine therapy for postmenopausal women with hormone-responsive breast cancer. With the widespread use of AI adjuvant endocrine therapy, a significant profile of musculoskeletal symptoms has emerged. Moderate to severe musculoskeletal symptoms have led some women to discontinue therapy, compromising the survival benefit. The etiology of AI-related musculoskeletal symptoms is poorly understood, which challenges development of effective management strategies. The purpose of this article is to describe AI-related musculoskeletal symptoms, review possible causes, provide assessment guidelines, and recommend management strategies based on the best available evidence. Little evidence exists for effective management strategies of AI-related musculoskeletal symptoms, and randomized clinical trials are needed to establish effective interventions. A thorough musculoskeletal assessment can help guide clinical decision making for the best individual management approach. Providers need to manage symptoms with the best available evidence to minimize symptom distress and maximize adherence to AI therapy.

Abstract
Nonpharmacogenetic factors may play a key role in the success of oral endocrine therapy for breast cancer. Adherence, defined as following medical advice as well as persistence and duration of use for patients prescribed endocrine therapy, may impact significantly on recurrence and survival. Side effects from tamoxifen or aromatase inhibitors may lead to patients stopping or switching therapy, while comorbidities, consequent coprescribing and patient perceptions may also influence outcomes. Interventions to improve adherence and persistence are required and could have as great an effect on survival as applying pharmacogenetic principles to the endocrine management of breast cancer.

Abstract
Tamoxifen and aromatase inhibitors are associated with side effects which can significantly impact quality of life (QoL). We assessed QoL in the Tamoxifen Exemestane Adjuvant Multinational (TEAM) Trial and compared these data with reported adverse events in the main database. 2,754 Dutch postmenopausal early breast cancer patients were randomized between 5 years of exemestane, or tamoxifen (2.5–3 years) followed by exemestane (2.5–2 years). 742 patients were invited to participate in the QoL side study and complete questionnaires at 1 (T1) and 2 (T2) years after start of endocrine treatment. Questionnaires comprised the EORTC QLQ-C30 and BR23 questionnaires, supplemented with FACT-ES questions. 543 patients completed questionnaires at T1 and 454 patients (84 %) at T2. Overall QoL and most functioning scales improved over time. The only clinically relevant and statistically significant difference between treatment types concerned insomnia; exemestane-treated patients reported more insomnia than tamoxifen-treated patients. Discrepancy was observed between QoL issue scores reported by the patients and adverse events reported by physicians. Certain QoL issues are treatment- and/or time-specific and deserve attention by health care providers. There is a need for careful inquiry into QoL issues by those prescribing endocrine treatment to optimize QoL and treatment adherence.

Abstract
Health-related quality of life (HRQOL), symptoms of depression, and adverse events (AEs) were compared between Japanese postmenopausal patients with hormone-sensitive breast cancer (BC) who received adjuvant tamoxifen, exemestane, or anastrozole in an open-labeled, randomized, multicenter trial designated as the National Surgical Adjuvant Study of Breast Cancer (N-SAS BC) 04 substudy of the Tamoxifen Exemestane Adjuvant Multinational (TEAM) trial. During the first year of treatment, HRQOL and symptoms of depression were analyzed using the Functional Assessment of Cancer Therapy-Breast (FACT-B) and its Endocrine Symptom Subscale (ES), and the Center for Epidemiologic Studies Depression Scale (CES-D), respectively. In addition, predefined AEs were analyzed. A total of 166 eligible patients were randomly assigned to receive adjuvant tamoxifen, exemestane, or anastrozole. FACT-B scores increased after treatment began and remained significantly higher in the tamoxifen group than in the exemestane group or anastrozole group during the first year (P = 0.045). FACT-B scores were similar in the exemestane group and anastrozole group. ES scores and CES-D scores were similar in all treatment groups. Arthralgia and fatigue were less frequent, but vaginal discharge was more frequent in the tamoxifen group than in the exemestane group or anastrozole group. HRQOL was better in Japanese postmenopausal women treated with tamoxifen than those treated with exemestane or anastrozole. HRQOL and AEs were similar with exemestane and anastrozole. Given the results of the TEAM trial, upfront use of tamoxifen followed by an aromatase inhibitor (AI) may be an important option for adjuvant endocrine therapy in Japanese postmenopausal women.

Abstract
The current adjuvant therapy for breast cancer is in a continous progress; standard therapeutic strategies include the use of chemotherapy, molecular targeted drugs and hormonal agents, according to well-established prognostic and predictive factors. Among the hormonal drugs, for a long period tamoxifen has been the gold standard of adjuvant therapy in postmenopausal women with hormone receptor-positive (HR+) early breast cancer. In the last years an expanding use of aromatase inhibitors occurred in this subset of patients, because the third-generation class of these agents (anastrozole, letrozole and exemestane) showed to be more effective and safe than tamoxifen and are now recommended as the preferred hormonal approach to postmenopausal hormone-sensitive patients, according to national and international guidelines. Treatment choices with these agents include the use of an aromatase inhibitor as an upfront strategy for 5 years, as a sequential approach after 2-3 years of tamoxifen, or as an extended use after the classical 5 years of tamoxifen. The improved efficacy of aromatase inhibitors over tamoxifen has been largely demonstrated in terms of better disease-free survival, reductions in the occurrence of early distant metastasis as well as improvement of overall survival. Moreover, according to the optimal duration of therapy, presently it is not known whether aromatase inhibitor therapy, as tamoxifen, should be limited to 5 years. In terms of safety profile, the side effects of aromatase inhibitors, as compared with selective estrogen receptor modulators, are different, reflecting the specific mechanism of action of these drugs. There is strong evidence that aromatase inhibitors are well tolerated, with a lower incidence of gynecological symptoms (vaginal bleeding, discharge and endometrial neoplasia), venous thromboembolic events and hot flushes than tamoxifen. On the other hand, the use of aromatase inhibitors has been associated with loss of bone density, arthralgia, myalgia, and a negative effect on lipid metabolism and cardiovascular risk. More extensive and mature studies are necessary to well establish the safety of aromatase inhibitors when given to patients with breast cancer for a long time.

Abstract
OBJECTIVES To examine self-reported menopausal-type symptoms among breast cancer patients on aromatase inhibitors (AIs) compared to women of the same age who had not been diagnosed with cancer, and to determine whether the percentage of breast cancer patients experiencing these symptoms changed over the first 6 months of AI treatment. METHODS Data from a 6-month cohort study of 100 breast cancer patients initiating AI therapy and of 200 women of a similar age without a history of cancer were analyzed. At baseline (prior to the initiation of AI therapy among the breast cancer patients), 3 months, and 6 months, a comprehensive questionnaire was administered to participants that ascertained data on the experiencing of specific menopausal-type symptoms. RESULTS The data showed statistically significant increases in the prevalence of certain symptoms from baseline to either follow-up point among the breast cancer patients; these symptoms included hot flushes, night sweats, pain during intercourse, hair loss, forgetfulness, depression, difficulty falling asleep, and interrupted sleep. Additionally, breast cancer patients were more likely than the women in the comparison group to report the new onset of many of these same symptoms during the follow-up time period. CONCLUSIONS Because bothersome symptoms and side-effects are a major reason for discontinuation and non-adherence to treatment, symptoms should be monitored and addressed by oncologists so that the breast cancer patient can maintain her quality of life and remain adherent to the treatment schedule.

Abstract
The adjuvant treatment of women with endocrine-sensitive early breast cancer has been dominated for the last 40 years by tamoxifen. However, the side-effects associated with this therapy have prompted a search for safer and biochemically more selective endocrine agents and led to the development of the third-generation aromatase inhibitors (AIs) anastrozole, letrozole and exemestane. Promising results in advanced disease have paved the way for treating early breast cancer, and AIs are increasingly replacing tamoxifen in the adjuvant setting. Several large, randomized trials with AIs have been completed or are ongoing in women with early-stage breast cancer, documenting the significant impact that these drugs are making on the risk for recurrence of breast cancer. As a result, there is increasing and widespread use of AI therapy for the treatment of early-stage endocrine-responsive breast cancer. This review summarizes the data for exemestane in the adjuvant setting, showing that a switch to exemestane after 2 to 3 years of tamoxifen therapy is associated with a statistically significant survival benefit and is regarded as being sensitive by international and national experts.

Abstract
Exemestane is an irreversible inhibitor of the aromatase enzyme, which is a key component in the production of estrogen. The majority of breast cancers are sensitive to the proliferative effects of estrogen. Exemestane is approved for the adjuvant treatment of postmenopausal women with breast cancer after 2 to 3 years of tamoxifen therapy, based on a 32% improvement in disease-free survival compared with 5 years of tamoxifen alone (P < 0.001). Exemestane has also shown clinical benefits as an upfront therapy. The safety profile of exemestane shares some side effects with tamoxifen (hot flashes and arthralgia), but is not associated with an increased risk of endometrial cancer or thromboembolic events. This review will discuss in detail the efficacy and safety of exemestane in early breast cancer.

Abstract
Estrogen deficiency at menopause is associated with increased risk of bone loss and osteoporosis. Aromatase inhibitors (AIs) are increasingly being used for the treatment of postmenopausal hormone-sensitive breast cancer because of better disease-free survival compared with tamoxifen seen in clinical trials with AIs. This article reviews the effect of endocrine therapies of breast cancer on bone and the management of bone disease with these endocrine therapies. The effect of these therapies on bone mineral density and bone turnover along with possible interventions is discussed. AIs are also associated with skeletal-related events, which are not discussed.

Abstract
BACKGROUND Aromatase inhibitors improved disease-free survival compared with tamoxifen when given as an initial adjuvant treatment or after 2-3 years of tamoxifen to postmenopausal women with hormone-receptor-positive breast cancer. We therefore compared the long-term effects of exemestane monotherapy with sequential treatment (tamoxifen followed by exemestane). METHODS The Tamoxifen Exemestane Adjuvant Multinational (TEAM) phase 3 trial was conducted in hospitals in nine countries. Postmenopausal women (median age 64 years, range 35-96) with hormone-receptor-positive breast cancer were randomly assigned in a 1:1 ratio to open-label exemestane (25 mg once a day, orally) alone or following tamoxifen (20 mg once a day, orally) for 5 years. Randomisation was by use of a computer-generated random permuted block method. The primary endpoint was disease-free survival (DFS) at 5 years. Main analyses were by intention to treat. The trial is registered with ClinicalTrials.gov, NCT00279448, NCT00032136, and NCT00036270; NTR 267; Ethics Commission Trial27/2001; and UMIN, C000000057. FINDINGS 9779 patients were assigned to sequential treatment (n=4875) or exemestane alone (n=4904), and 4868 and 4898 were analysed by intention to treat, respectively. 4154 (85%) patients in the sequential group and 4186 (86%) in the exemestane alone group were disease free at 5 years (hazard ratio 0·97, 95% CI 0·88-1·08; p=0·60). In the safety analysis, sequential treatment was associated with a higher incidence of gynaecological symptoms (942 [20%] of 4814 vs 523 [11%] of 4852), venous thrombosis (99 [2%] vs 47 [1%]), and endometrial abnormalities (191 [4%] vs 19 [<1%]) than was exemestane alone. Musculoskeletal adverse events (2448 [50%] vs 2133 [44%]), hypertension (303 [6%] vs 219 [5%]), and hyperlipidaemia (230 [5%] vs 136 [3%]) were reported more frequently with exemestane alone. INTERPRETATION Treatment regimens of exemestane alone or after tamoxifen might be judged to be appropriate options for postmenopausal women with hormone-receptor-positive early breast cancer.

Abstract
BACKGROUND Quality-of-life (QOL) measurement is often incorporated into randomized clinical trials in breast cancer. The objectives of this systematic review were to assess the incremental effect of QOL measurement in addition to traditional endpoints (such as disease-free survival or toxic effects) on clinical decision making and to describe the extent of QOL reporting in randomized clinical trials of breast cancer. METHODS We conducted a search of MEDLINE for English-language articles published between May-June 2001 and October 2009 that reported: 1) a randomized clinical trial of breast cancer treatment (excluding prevention trials), including surgery, chemotherapy, hormone therapy, symptom control, follow-up, and psychosocial intervention; 2) the use of a patient self-report measure that examined general QOL, cancer-specific or breast cancer-specific QOL or psychosocial variables; and 3) documentation of QOL outcomes. All selected trials were evaluated by two reviewers, and data were extracted using a standardized form for each variable. Data are presented in descriptive table formats. RESULTS A total of 190 randomized clinical trials were included in this review. The two most commonly used questionnaires were the European Organization for Research and Treatment of Cancer QOL Questionnaire and the Functional Assessment of Cancer Therapy/Functional Assessment of Chronic Illness Therapy. More than 80% of the included trials reported the name(s) of the instrument(s), trial and QOL sample sizes, the timing of QOL assessment, and the statistical method. Statistical power for QOL was reported in 19.4% of the biomedical intervention trials and in 29.9% of the nonbiomedical intervention trials. The percentage of trials in which QOL findings influenced clinical decision making increased from 15.2% in the previous review to 30.1% in this updated review for trials of biomedical interventions but decreased from 95.0% to 63.2% for trials of nonbiomedical interventions. Discordance between reviewers ranged from 1.1% for description of the statistical method (yes vs no) to 19.9% for the sample size for QOL. CONCLUSION Reporting of QOL methodology could be improved.

Abstract
OBJECTIVE To investigate the prevalence of urogenital symptoms and vaginal atrophy in postmenopausal breast cancer patients on adjuvant endocrine therapy. STUDY DESIGN A population-based, cross-sectional study on postmenopausal breast cancer patients on adjuvant endocrine treatment and age-matched control subjects. Vaginal atrophy was assessed by gynecologic examination and atrophy-related symptoms by validated questionnaires. RESULTS In all, 57.6% of aromatase inhibitor-treated and 32.4% of tamoxifen-treated breast cancer patients rated at least 1 vaginal atrophy symptom as moderate/severe, which was significantly more common than in control subjects (P < .01). Aromatase inhibitor-treated patients more often had moderate or severe vaginal atrophy (P < .05), a more atrophic cytohormonal evaluation, and significantly higher vaginal pH (P < .05) than all control subjects, irrespective of hormonal use. CONCLUSION Our findings indicate that the frequency of vaginal atrophy symptoms, particularly in aromatase inhibitor-treated women, might have been underestimated in previous clinical trials.

Abstract
INTRODUCTION Breast cancer (BC) remains the most common non-skin cancer in women and an increasing number are living as BC survivors. AIM The aim of this article is to evaluate the impact of the first diagnosis of invasive BC and its treatment, menopausal symptoms, and body image on sexual function. METHODS The BUPA Foundation Health and Wellbeing after Breast Cancer Study is a prospective cohort study of 1,684 women recruited within 12 months of their first diagnosis with invasive BC. Each participant completed an enrollment questionnaire (EQ) and first follow-up questionnaire (FQ1) 12 months post-EQ. MAIN OUTCOME MEASURE Sexual function was evaluated by the Menopause-Specific Quality of Life Questionnaire embedded within the FQ1. RESULTS Of the 1,011 women in the analyses, 70% experienced sexual function problems and 77% reported vasomotor symptoms. Women experiencing sexual function problems were postmenopausal (P = 0.02), experienced vasomotor symptoms (P < 0.01), and used aromatase inhibitors (P = 0.03). Women with vasomotor symptoms were twice as likely to experience sexual function problems (odds ratio [OR] 1.93, 95% confidence interval [CI] 141, 2.63; P < 0.001). This association was more extreme for women on aromatase inhibitors (OR 3.49, 95% CI 1.72, 7.09; P = 0.001) but did not persist in women not using endocrine therapies (OR 1.41, 95% CI 0.84, 2.36; P = 0.19). Women on aromatase inhibitors were more likely to report sexual function problems (OR 1.50, 95% CI 1.0, 2.2, P = 0.04) and women with body image issues were 2.5 times more likely to report sexual function problems (OR 2.5 95% CI 1.6, 3.7, P < 0.001). Women using tamoxifen were not more likely to experience sexual function problems (OR 1.1, 95% CI 0.8, 1.5, P = 0.6); however, women with body image issues were twice as likely to experience sexual function problems (OR 2.1, 95% CI 1.5, 3.0, P < 0.001). CONCLUSION Seventy percent of partnered BC survivors less than 70 experienced sexual function problems. Sexual problems are related to the use of aromatase inhibitors which can exacerbate menopausal symptoms.

Abstract
AIMS In breast cancer survivors, we aimed to describe the frequency of hot flashes and night sweats, frequency and type of treatment, and the association of hot flashes and use of calcium supplements. METHODS Charts of breast cancer survivors were reviewed for information about hot flashes, treatment for hot flashes, and calcium supplementation. Associations between variables were explored using the Chi-square test and Fisher's Exact test. RESULTS Eighty-six charts were reviewed. Mean age of the women was 58 years and 79% were postmenopausal. Forty-two (49%) of women had hot flashes and 18 (21%) had night sweats. Thirty-one (36%) were treated for hot flashes. Treatment included selective serotonin reuptake inhibitors/serotonin-norepinephrine reuptake inhibitors (n = 19), clonidine (n = 7), Bellergal-S(®) (n = 8), sleep-aid (n = 7), and other (n = 5). Calcium supplementation was recorded in 31%. Of women with hot flashes, 44% took calcium supplements; of women without hot flashes, 18% took calcium supplements (Chi-square P = 0.02). CONCLUSION Hot flashes were recorded in 49% of this group of primarily postmenopausal breast cancer survivors. Women with hot flashes were more likely to be taking calcium supplements. Further exploration of the association between hot flashes and calcium supplementation is warranted.

Musculoskeletal adverse events associated with adjuvant aromatase inhibitors. JOURNAL OF ONCOLOGY 2010; 2010. [PMID: 20871846 PMCID: PMC2943085 DOI: 10.1155/2010/654348] [Citation(s) in RCA: 34] [Impact Index Per Article: 2.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 12/22/2009] [Revised: 05/14/2010] [Accepted: 07/11/2010] [Indexed: 11/21/2022]
Abstract
Musculoskeletal symptoms including arthralgia and myalgia occur frequently in aging women, particularly during the transition to menopause, when plasma estrogens precipitously decline. In postmenopausal women (PMW) with breast cancer, third-generation aromatase inhibitors (AIs) as adjuvant hormonal therapy have proven to be more effective, and to have a more predictable side effect profile, than tamoxifen. However, AIs further reduce plasma estrogens in PMW, exacerbating musculoskeletal symptoms. Clinical trial data have shown significantly higher incidences of arthralgia and myalgia with AIs compared with women on tamoxifen or placebo. Symptoms may be severe enough to significantly affect quality of life; musculoskeletal symptoms are a frequent reason for discontinuing therapy. In many cases, symptoms can be effectively managed with oral analgesics or other strategies. Early recognition and effective management of musculoskeletal symptoms can help maximize treatment compliance, enabling patients to derive optimal benefit from therapy in terms of preventing recurrence.
