RESUMEN

BACKGROUND: Prospective data on the risk of recurrence among women with hormone receptor-positive early breast cancer who temporarily discontinue endocrine therapy to attempt pregnancy are lacking. METHODS: We conducted a single-group trial in which we evaluated the temporary interruption of adjuvant endocrine therapy to attempt pregnancy in young women with previous breast cancer. Eligible women were 42 years of age or younger; had had stage I, II, or III disease; had received adjuvant endocrine therapy for 18 to 30 months; and desired pregnancy. The primary end point was the number of breast cancer events (defined as local, regional, or distant recurrence of invasive breast cancer or new contralateral invasive breast cancer) during follow-up. The primary analysis was planned to be performed after 1600 patient-years of follow-up. The prespecified safety threshold was the occurrence of 46 breast cancer events during this period. Breast cancer outcomes in this treatment-interruption group were compared with those in an external control cohort consisting of women who would have met the entry criteria for the current trial. RESULTS: Among 516 women, the median age was 37 years, the median time from breast cancer diagnosis to enrollment was 29 months, and 93.4% had stage I or II disease. Among 497 women who were followed for pregnancy status, 368 (74.0%) had at least one pregnancy and 317 (63.8%) had at least one live birth. In total, 365 babies were born. At 1638 patient-years of follow-up (median follow-up, 41 months), 44 patients had a breast cancer event, a result that did not exceed the safety threshold. The 3-year incidence of breast cancer events was 8.9% (95% confidence interval [CI], 6.3 to 11.6) in the treatment-interruption group and 9.2% (95% CI, 7.6 to 10.8) in the control cohort. CONCLUSIONS: Among select women with previous hormone receptor-positive early breast cancer, temporary interruption of endocrine therapy to attempt pregnancy did not confer a greater short-term risk of breast cancer events, including distant recurrence, than that in the external control cohort. Further follow-up is critical to inform longer-term safety. (Funded by ETOP IBCSG Partners Foundation and others; POSITIVE ClinicalTrials.gov number, NCT02308085.).

RESUMEN

Tools have been developed to facilitate communication and support information exchange between people diagnosed with cancer and their physicians. Patient-reported outcome measures, question prompt lists, patient-held records, tape recordings of consultations, decision aids, and survivorship care plans have all been promoted as potential tools, and there is extensive literature exploring their impact on patient outcomes. Eleven systematic reviews of studies evaluating tools to facilitate patient-physician communication were reviewed and summarized in this overview of systematic reviews. Across the systematic reviews, 87 publications reported on 84 primary studies involving 15,381 participants. Routine use of patient-reported outcome measures and feedback of results to clinicians can improve pain management, physician-patient communication, and symptom detection and control; increase utilization of supportive care; and increase patient involvement in care. Question prompt lists can increase the number of questions asked by patients without increasing consultation length and may encourage them to reflect and plan questions before the consultation. There is limited benefit in audio recording consultations or using patient-held records during consultations. Physicians should be supported by adequately resourced health services to respond effectively to the range of clinical and broader patient needs identified through the routine use of tools to facilitate communication.

RESUMEN

PURPOSE: Age and body mass index (BMI) are critical considerations when assessing individual breast cancer risk, particularly for women with dense breasts. However, age- and BMI-standardized estimates of breast density are not available for screen-aged women, and little is known about the distribution of breast density in women aged < 40. This cross-sectional study uses three different modalities: optical breast spectroscopy (OBS), dual-energy X-ray absorptiometry (DXA), and mammography, to describe the distributions of breast density across categories of age and BMI. METHODS: Breast density measures were estimated for 1,961 Australian women aged 18-97 years using OBS (%water and %water + %collagen). Of these, 935 women had DXA measures (percent and absolute fibroglandular dense volume, %FGV and FGV, respectively) and 354 had conventional mammographic measures (percent and absolute dense area). The distributions for each breast density measure were described across categories of age and BMI. RESULTS: The mean age was 38 years (standard deviation = 15). Median breast density measures decreased with age and BMI for all three modalities, except for DXA-FGV, which increased with BMI and decreased after age 30. The variation in breast density measures was largest for younger women and decreased with increasing age and BMI. CONCLUSION: This unique study describes the distribution of breast density measures for women aged 18-97 using alternative and conventional modalities of measurement. While this study is the largest of its kind, larger sample sizes are needed to provide clinically useful age-standardized measures to identify women with high breast density for their age or BMI.

RESUMEN

PURPOSE: When a pregnant woman is diagnosed with cancer, she faces complex and unique challenges while navigating both obstetric and oncological care. Despite often being the primary support for women diagnosed with cancer during pregnancy (CDP), little is known about the experiences of their partners. We undertook an in-depth exploration of the experiences of partners of women diagnosed with CDP in Australia. METHODS: Semi-structured interviews were conducted with partners of women diagnosed with CDP treated in Australia. Interviews explored partners' inclusion in decision making and communication with health professionals and their own coping experiences. Data were analysed thematically. RESULTS: Data from interviews with 12 male partners (N = 12) of women diagnosed with CDP were analysed. Two unique themes relevant to partners were identified: 'Partners require support to adjust to changing roles and additional burdens' and 'Treating the couple as a team facilitates agency and coping, but partners' needs are placed second by all'. CONCLUSION: Partners of women diagnosed with CDP commonly experience unique stressors and a substantial shift in previously established roles across multiple domains including medical advocacy, household coordination and parenting. Partners' coping is interlinked with how the woman diagnosed with CDP is coping. Inclusion of partners in treatment decisions and communications, and considering partners' wellbeing alongside that of the woman with CDP, is likely to be supportive for partners. In turn, this is likely to enhance the quality of support that women diagnosed with CDP receive from their partners.

RESUMEN

INTRODUCTION: The study examined whether increased physical activity (PA) in nonmetropolitan cancer survivors was maintained 12 weeks following the PPARCS intervention. METHODS: PA outcomes were assessed using an accelerometer at baseline, end of the intervention, and at 24 weeks. Linear mixed models were used to examine between-group changes in PA outcomes. RESULTS: The increased moderate-to-vigorous PA (MVPA) following intervention was maintained with significantly higher MVPA in the intervention group at 24 weeks (vs. controls) compared to baseline nett change of 52.5 min/week (95% CI 11.0-94.0.4). CONCLUSIONS: Distance-based interventions using wearables and health coaching may produce MVPA maintenance amongst nonmetropolitan cancer survivors.

RESUMEN

Sentinel node biopsy (SNB) is routinely performed in people with node-negative early breast cancer to assess the axilla. SNB has no proven therapeutic benefit. Nodal status information obtained from SNB helps in prognostication and can influence adjuvant systemic and locoregional treatment choices. However, the redundancy of the nodal status information is becoming increasingly apparent. The accuracy of radiological assessment of the axilla, combined with the strong influence of tumour biology on systemic and locoregional therapy requirements, has prompted many to consider alternative options for SNB. SNB contributes significantly to decreased quality of life in early breast cancer patients. Substantial improvements in workflow and cost could accrue by removing SNB from early breast cancer treatment. We review the current viewpoints and ideas for alternative options for assessing and managing a clinically negative axilla in patients with early breast cancer (EBC). Omitting SNB in selected cases or replacing SNB with a non-invasive predictive model appear to be viable options based on current literature.

RESUMEN

BACKGROUND: Obesity has been recognized as a risk factor in the development and recurrence of breast cancer and is also associated with poor prognostic outcomes. This systematic review and network meta-analysis aimed to identify the most effective exercise, physical activity, and dietary interventions to reduce fat mass, body fat percentage and body weight as well as potentially increase lean mass in women diagnosed with or at high risk of breast cancer. METHODS: A systematic search of databases was performed up to May 2022. Eligible randomized controlled trials examined the effects of exercise, physical activity and/or dietary interventions on fat mass and lean mass in women diagnosed with or at high risk of breast cancer. A random-effects network meta-analysis was conducted to determine the effects of different interventions across outcomes when sufficient studies were available. RESULTS: Eighty-four studies (n = 6428) were included in this review. Caloric restriction and combined exercise + caloric restriction significantly reduced fat mass (range, -3.9 to -3.7 kg) and body weight (range, -5.3 to -4.7 kg), whereas physical activity + caloric restriction significantly reduced body fat percentage (-2.4%; 95% confidence interval [CI], -3.4% to -13%) and body mass index (-2.2 kg × m-2 ; 95% CI, -3.0 to -1.4 kg × m-2 ) in breast cancer patients. Resistance exercise was the most effective intervention to increase lean mass (0.7 kg; 95% CI, 0.5-1.0 kg) in breast cancer patients. CONCLUSION: Multimodal exercise and diet programs were the most effective interventions to reduce fat mass, body fat percentage, and body weight and increase and/or preserve lean mass.

RESUMEN

BACKGROUND: Breast density is a strong and potentially modifiable breast cancer risk factor. Almost everything we know about breast density has been derived from mammography, and therefore, very little is known about breast density in younger women aged <40. This study examines the acceptability and performance of two alternative breast density measures, Optical Breast Spectroscopy (OBS) and Dual X-ray Absorptiometry (DXA), in women aged 18-40. METHODS: Breast tissue composition (percent water, collagen, and lipid content) was measured in 539 women aged 18-40 using OBS. For a subset of 169 women, breast density was also measured via DXA (percent fibroglandular dense volume (%FGV), absolute dense volume (FGV), and non-dense volume (NFGV)). Acceptability of the measurement procedures was assessed using an adapted validated questionnaire. Performance was assessed by examining the correlation and agreement between the measures and their associations with known determinants of mammographic breast density. RESULTS: Over 93% of participants deemed OBS and DXA to be acceptable. The correlation between OBS-%water + collagen and %FGV was 0.48. Age and BMI were inversely associated with OBS-%water + collagen and %FGV and positively associated with OBS-%lipid and NFGV. CONCLUSIONS: OBS and DXA provide acceptable and viable alternative methods to measure breast density in younger women aged 18-40 years.

RESUMEN

BACKGROUND: Building health literacy about potentially modifiable risk factors for breast cancer may help to empower women to make more informed decisions about their breast health; however there has been limited qualitative research on this topic. This study aimed to explore current knowledge, understanding and experience of potentially modifiable risk factors for breast cancer, and views on current and future communication strategies for this information and related interventions. METHODS: Qualitative study using online focus groups via Zoom in October-November 2022. A diverse sample of women from the Australian community aged 40-74 years were recruited. RESULTS: Fifty-one women from a range of socioeconomic backgrounds took part in nine focus groups. General knowledge of risk factors for breast cancer in the community is limited, particularly in relation to modifiable factors such as alcohol consumption and postmenopausal obesity, with many women describing feelings of 'shock' following this information. Women overwhelming believed that information on modifiable risk factors for breast cancer should be communicated more widely, however communication preferences for receiving this information varied. There was a strong preference amongst the women for a cascade of information which they believed may then help target greater number of women of all ages and backgrounds. Despite worry about long-term compliance, women also supported various lifestyle interventions which may help them and other women to reduce their overall risk. CONCLUSIONS: Findings from this study highlight the need for more widespread community communication and education about risk factors for breast, in particular potentially modifiable risk factors such as alcohol consumption and postmenopausal obesity. As breast screening programs in Australia and globally begin to evaluate the potential for risk-related screening this will provide an additional context for primary prevention, hence planning of messaging and piloting of lifestyle-related prevention strategies in breast cancer is needed now. Gaining an understanding of women's preferences for communication and forms of interventions is vital to ensure their engagement.

RESUMEN

The demand for palliative care (PC) is ever-increasing globally. The emergence of COVID-19 pandemic has further accelerated the need for PC. In the lower-income countries (LICs), where PC need is highest, PC, the most humane, appropriate and realistic approach to care for patients and families affected by life-limiting illness, is minimal or non-existent. Recognising the disparity between high, middle and LICs, the World Health Organization (WHO) has recommended public health strategies for PC within the socioeconomic, cultural and spiritual contexts of individual countries. This review aimed to: (i) identify PC models in the LICs utilising public health strategies and (ii) characterise how social, cultural and spiritual components were integrated into these models. This is an integrative literature review. Thirty-seven articles were included from a search of four electronic databases - Medline, Embase, Global Health and CINAHL. Literature, both empirical and theoretical literature, published in English from January 2000 to May 2021 that mentioned PC models/services/programmes integrating public health strategies in the LICs were included in the study. A number of LICs utilised public health strategies to deliver PC. One-third of the selected articles highlighted the importance of integrating sociocultural and spiritual components into PC. Two main themes - WHO-recommended public health framework and sociocultural and spiritual support in PC and five subthemes - (i) suitable policies; (ii) availability and accessibility of essential drugs; (iii) PC education for health professionals, policymakers and the public; (iv) implementation of PC at all levels of healthcare and (v) sociocultural and spiritual components, were derived. Despite embracing the public health approach, many LICs encountered several challenges in integrating all four strategies successfully.

RESUMEN

Breast cancer is the commonest human cancer globally and one in seven Australian women will develop it in their lifetime. Surgery is the mainstay of management both for women who are at high risk of breast cancer and for those who have been diagnosed. Increased understanding of how to predict who is most at risk of breast cancer is leading to the possibility of risk-based screening, allowing better and more targeted early detection for women at high risk, and contrast imaging techniques are proving more accurate in diagnosing and staging cancer. The evolution of surgical practice includes the widespread use of oncoplastic surgery, allowing better cosmetic and oncological outcomes; reconstructive surgical advances, using free flap techniques; and sequencing of systemic and local therapies to better tailor treatments to the patient's cancer and improve outcomes. Recognition of side effects of breast cancer treatment have led to improvement in the management of conditions such as chronic pain and lymphoedema, as well as addressing the psychosocial, body image and sexual complications caused by the cancer and its treatment.

RESUMEN

BACKGROUND: People with advanced cancer often experience greater physical and psychosocial morbidity compared to those with early disease. Limited research has focused on their experiences within the Australian health system. The aim of this study was to explore the lived experiences of adults receiving care for advanced cancer. METHODS: A qualitative design with a descriptive phenomenological approach was used to explore the lived experiences of people with advanced cancer following their diagnosis. Twenty-three people living with an advanced solid malignancy receiving care were referred by their oncologists to take part in an interview conducted at their home, the hospital, or over the phone. RESULTS: Three key themes emerged relating to participants' experiences of living with advanced cancer: (1) living with a life-limiting diagnosis and uncertainty, (2) living with symptom burden and side effects, and (3) living within the health system, with two subthemes, the patient-clinician relationship, and care coordination. Participant relationships with their health professionals were particularly important and had a defining impact on whether patient experiences living with cancer were positive or negative. CONCLUSION: People with advanced cancer experienced broad variation in their experiences navigating the health system, and their relationships with clinicians and other health professionals were important factors affecting their perceptions of their experiences. Attention to the coordination of care for people with advanced cancer is necessary to improve their experiences and improve symptom control and the management of their psychosocial burden.

RESUMEN

OBJECTIVE: To determine the epidemiology, clinical management, and outcomes of women with gestational breast cancer (GBC). METHODS: A population-based prospective cohort study was conducted in Australia and New Zealand between 2013 and 2014 using the Australasian Maternity Outcomes Surveillance System (AMOSS). Women who gave birth with a primary diagnosis of breast cancer during pregnancy were included. Data were collected on demographic and pregnancy factors, GBC diagnosis, obstetric and cancer management, and perinatal outcomes. The main outcome measures were preterm birth, maternal complications, breastfeeding, and death. RESULTS: Forty women with GBC (incidence 7.5/100 000 women giving birth) gave birth to 40 live-born babies. Thirty-three (82.5%) women had breast symptoms at diagnosis. Of 27 women diagnosed before 30 weeks' gestation, 85% had breast surgery and 67% had systemic therapy during pregnancy. In contrast, all 13 women diagnosed from 30 weeks had their cancer management delayed until postdelivery. There were 17 preterm deliveries; 15 were planned. Postpartum complications included the following: hemorrhage (n = 4), laparotomy (n = 1), and thrombocytopenia (n = 1). There was one late maternal death. Eighteen (45.0%) women initiated breastfeeding, including 12 of 23 women who had antenatal breast surgery. There were no perinatal deaths or congenital malformations, but 42.5% of babies were preterm, and 32.5% were admitted for higher-level neonatal care. CONCLUSIONS: Gestational breast cancer diagnosed before 30 weeks' gestation was associated with surgical and systemic cancer care during pregnancy and planned preterm birth. In contrast, cancer treatment was deferred to postdelivery for women diagnosed from 30 weeks, reflecting the complexity of managing expectant mothers with GBC in multidisciplinary care settings.

RESUMEN

BACKGROUND: The TARGIT-A trial reported risk-adapted targeted intraoperative radiotherapy (TARGIT-IORT) during lumpectomy for breast cancer to be as effective as whole-breast external beam radiotherapy (EBRT). Here, we present further detailed analyses. METHODS: In total, 2298 women (≥45 years, invasive ductal carcinoma ≤3.5 cm, cN0-N1) were randomised. We investigated the impact of tumour size, grade, ER, PgR, HER2 and lymph node status on local recurrence-free survival, and of local recurrence on distant relapse and mortality. We analysed the predictive factors for recommending supplemental EBRT after TARGIT-IORT as part of the risk-adapted approach, using regression modelling. Non-breast cancer mortality was compared between TARGIT-IORT plus EBRT vs. EBRT. RESULTS: Local recurrence-free survival was no different between TARGIT-IORT and EBRT, in every tumour subgroup. Unlike in the EBRT arm, local recurrence in the TARGIT-IORT arm was not a predictor of a higher risk of distant relapse or death. Our new predictive tool for recommending supplemental EBRT after TARGIT-IORT is at https://targit.org.uk/addrt . Non-breast cancer mortality was significantly lower in the TARGIT-IORT arm, even when patients received supplemental EBRT, HR 0.38 (95% CI 0.17-0.88) P = 0.0091. CONCLUSION: TARGIT-IORT is as effective as EBRT in all subgroups. Local recurrence after TARGIT-IORT, unlike after EBRT, has a good prognosis. TARGIT-IORT might have a beneficial abscopal effect.

RESUMEN

Surgical resection of cancer remains the frontline therapy for millions of patients annually, but post-operative recurrence is common, with a relapse rate of around 45% for non-small cell lung cancer. The tumour draining lymph nodes (dLN) are resected at the time of surgery for staging purposes, and this cannot be a null event for patient survival and future response to immune checkpoint blockade treatment. This project investigates cancer surgery, lymphadenectomy, onset of metastatic disease, and response to immunotherapy in a novel model that closely reflects the clinical setting. In a murine metastatic lung cancer model, primary subcutaneous tumours were resected with associated dLNs remaining intact, completely resected or partially resected. Median survival after surgery was significantly shorter with complete dLN resection at the time of surgery (49 days (95%CI)) compared to when lymph nodes remained intact (> 88 days; p < 0.05). Survival was partially restored with incomplete lymph node resection and CD8 T cell dependent. Treatment with aCTLA4 whilst effective against the primary tumour was ineffective for metastatic lung disease. Conversely, aPD-1/aCD40 treatment was effective in both the primary and metastatic disease settings and restored the detrimental effects of complete dLN resection on survival. In this pre-clinical lung metastatic disease model that closely reflects the clinical setting, we observe decreased frequency of survival after complete lymphadenectomy, which was ameliorated with partial lymph node removal or with early administration of aPD-1/aCD40 therapy. These findings have direct relevance to surgical lymph node resection and adjuvant immunotherapy in lung cancer, and perhaps other cancer, patients.

RESUMEN

PURPOSE: To determine the nature and severity of vasomotor symptoms, sexual problems, mood and sleep disturbance in community-dwelling breast cancer patients, whether and where they received treatment for these symptoms and their satisfaction with treatment received. METHODS: Online cross-sectional survey distributed through Breast Cancer Network Australia (BCNA). RESULTS: 524/2286 women responded to the invitation to participate. Of these, 74% (385/523) reported symptoms of interest and were included in the analysis. Mean age was 55.2 years and mean time since breast cancer diagnosis was 5.7 years. Most (66%) had received chemotherapy and were taking endocrine therapy (64%). The most common symptoms were hot flushes/night sweats and sleep disturbance (both 89%), vaginal dryness (75%), mood swings (62%) and sexual problems (60%). Symptoms were mild (21-33%) or moderate (21-38%) in around one third and severe in up to one quarter (8-26%). Symptoms affected the ability to "get on with their life" for 36%, predicted by severity of hot flushes (OR 1.4), sleep disturbance (OR 1.3), mood disturbance (OR 1.3), and sexual problems (OR 1.3). Only 32% were offered treatment, mostly delivered by GPs (33%) or oncologists (26%). Only 49% found this "somewhat effective" and 34% found it ineffective. The majority (60%) wanted more support to manage their symptoms. CONCLUSION: Menopausal symptoms, sexual problems, mood and sleep difficulties are common after breast cancer and often not effectively managed. There is an unmet need for coordinated care providing effective treatments.

RESUMEN

Optical palpation maps stress at the surface of biological tissue into 2D images. It relies on measuring surface deformation of a compliant layer, which to date has been performed with optical coherence tomography (OCT). OCT-based optical palpation holds promise for improved clinical diagnostics; however, the complexity and cost hinder broad adoption. In this Letter, we introduce coherence function-encoded optical palpation (CFE-OP) using a novel optical profilometry technique that exploits the envelope of the coherence function rather than its peak position, which is typically used to retrieve depth information. CFE-OP utilizes a Fabry-Perot laser diode (bandwidth, 2.2 nm) and a single photodiode in a Michelson interferometer to detect the position along the coherence envelope as a function of path length. This technique greatly reduces complexity and cost in comparison to the OCT-based approach. We perform CFE-OP on phantom and excised human breast tissue, demonstrating comparable mechanical contrast to OCT-based optical palpation and the capability to distinguish stiff tumor from soft benign tissue.

RESUMEN

BACKGROUND: People living with advanced cancer experience significant distress and reduced quality of life due to their symptom burden and life-limiting prognosis. Limited qualitative research has investigated their experiences accessing psychosocial supportive care, and how it meets their needs. AIM: To explore patients' perspectives of the role of psychosocial support in their experiences of living with advanced cancer. METHODS: This study used an exploratory qualitative research design and drew upon a social constructionist interpretive framework. Semi-structured interviews were conducted with 23 participants. Participants were asked about their experiences accessing and using psychosocial support following their diagnosis. Audio-recorded interviews were transcribed and analysed using deductive thematic analysis. RESULTS: The following six themes can be used to describe participants' experiences with psychosocial support: (1) accessing different types of support, (2) appreciating support, (3) need, (4) difficulties accessing support, (5) knowing about support and (6) asking for support. Sources of psychosocial support included family and friends, health professionals, and psychosocial supportive care services. Not all participants were able to access care that met their needs; barriers included suitability of available support, accessibility and stigma surrounding support use. CONCLUSION: Participants experienced broad variation in their awareness and access to psychosocial support services to meet their needs. Providers of psychosocial supportive care for advanced cancer patients need to consider service accessibility issues. Future psychosocial interventions targeting people living with advanced cancer should consider these issues during development and implementation.

RESUMEN

OBJECTIVE: Interventions to increase physical activity (PA) in cancer survivors have often adopted a "one-size-fits-all" approach and may benefit from being tailored to psychological constructs associated with behavior. The study objective was to investigate the exercise preferences and psychological constructs related to PA among cancer survivors. METHODS: Posttreatment colorectal, endometrial, and breast cancer survivors (n = 183) living in metropolitan and nonmetropolitan areas completed survey measures of PA, exercise preferences, attitudes, self-efficacy, perceived behavioral control (PBC), and intention toward PA. RESULTS: A structural equation model with adequate fit and quality indices revealed that instrumental attitude and self-efficacy were related to PA intention. Intention was related to behavior and mediated the relationship between self-efficacy and behavior. Preferred exercise intensity was related to self-efficacy, PBC, attitudes, and intention, while preferred exercise company was related to self-efficacy and PBC. Participants preferred moderate-intensity PA (71%), specifically self-paced (52%) walking (65%) in an outdoor environment (58%). CONCLUSIONS: Since instrumental attitude and self-efficacy were associated with PA, incorporating persuasive communications targeting attitudes in PA interventions may promote PA participation. As cancer survivors who prefer low-intensity exercise and exercising with others report lower self-efficacy and PBC, interventions targeting confidence and successful experience in this group may also be warranted.

RESUMEN

PURPOSE: Breast cancer affects millions of women worldwide, and for many, therapy results in treatment-induced menopause. Menopausal symptoms in breast cancer survivors are often more severe, frequent, and of greater duration compared with natural menopause. Hot flushes and night sweats pose a significant burden for many women, with limited therapeutic options as menopausal hormone therapy is contraindicated. Guidelines recommend non-hormonal pharmacological agents including clonidine, gabapentin, and some antidepressants. However, some women may be reluctant to use medications due to concerns about side effects. The aim of this narrative review was to appraise recent evidence for nonpharmacological treatments for vasomotor symptoms in breast cancer survivors including cognitive behavioural therapy, hypnosis, yoga, mindfulness, acupuncture, and lifestyle changes. METHODS: A literature search was conducted. Studies were included if they were randomised and involved breast cancer survivors and nonpharmacological treatments for menopausal vasomotor symptoms. RESULTS: Twelve studies met the criteria, and three studies of exercise in healthy menopausal women were included. Cognitive behavioural therapy reduces menopausal symptoms and perceived impact of hot flushes and night sweats in breast cancer survivors and is cost effective. The efficacy of hypnosis as a treatment for menopausal vasomotor symptoms in women with breast cancer is supported by two randomised controlled trials. Yoga and acupuncture may reduce vasomotor symptom frequency and/or burden. Studies of exercise as an intervention for vasomotor symptoms in healthy menopausal women have not shown benefit. CONCLUSION: Evidence for nonpharmacological interventions supports cognitive behavioural therapy and hypnosis in the management of vasomotor symptoms in breast cancer survivors.
