Therapy In Breast Cancer Survivors Research Articles

Menopausal hormone therapy for breast cancer survivors.

The global incidence of breast cancer continues to increase and increasing efficacy of treatments has improved overall prognosis and survival with a resulting requisite focus on improving quality of life after cancer. Treatment inevitably results in symptoms of menopause and these symptoms may be more severe after cancer treatment compared to natural menopause and may pose a potential risk of early treatment discontinuation. Consequently, the global burden of successfully managing these symptoms is significant. There is a discordance between randomized and observational data regarding the risk of systemic menopausal hormone therapy and breast cancer recurrence; hormone receptor status is significant to recurrence risk in this setting. The systemic absorption of local oestrogen is not a consistent surrogate marker for cancer recurrence and clinical data has not demonstrated a consistent increase in the risk of cancer recurrence with local therapy. Nonhormonal treatments remain first-line management of menopause symptoms in breast cancer survivors to minimize the risk of cancer recurrence. However, severe symptoms not responding to nonhormonal interventions require a multidisciplinary, patient-centred approach to discuss the evidence base for hormonal treatments.

Menopausal Hormone Therapy in Breast Cancer Survivors.

Menopausal symptoms negatively impact quality of life in breast cancer survivors. The paucity of data on the impact of Menopausal Hormone Therapy (MHT) on oncological outcomes in these patients limits informed clinical discussion. Defining the risk of cancer recurrence with MHT is central to the appraisal of risk/benefit, particularly with low-risk disease (based on genomic profile). The aim of this review is to summarize the current data evaluating MHT in breast cancer patients. A systematic review of the literature was performed to evaluate the impact of MHT on oncological outcomes in breast cancer survivors. Three major databases (PubMed, EMBASE and Medline) were searched. The review included all prospective studies published in English. Four randomized control trials and four non-randomized prospective studies were identified. An increase in breast cancer recurrence with MHT was observed in the early randomized trials whilst no increased risk of recurrence was reported in the observational studies. There remains a need to quantify MHT-related recurrence risk in patients with molecularly favorable disease.

Abstract PO2-19-12: Enhancing skin appearance and quality of life in breast cancer survivors on aromatase inhibitor therapy

Abstract Background: Post-menopausal women with estrogen receptor positive breast cancer (BC) are typically prescribed endocrine therapy with an aromatase inhibitor (AI) for 5-10 years following BC diagnosis. AIs have multiple established side effects related to estrogen deprivation including vasomotor symptoms, vaginal dryness, and accelerated bone thinning. Many patients also complain about the impact of AIs on skin quality; however, limited data currently exists, particularly with objective measurements of skin quality. Canfield Sciences VISIA-CA is a device that can be used to objectively measure skin changes using patented comparison to norms analysis with a skin feature database to grade the skin relative to others in the same age and skin type. Herein, we aim to evaluate changes in skin quality with the Canfield Sciences VISIA-CA Device after initiation of AI therapy and investigate potential benefits of skincare intervention. Trial Design: This is a pilot study aiming to describe changes in skin quality after initiation of AI therapy in BC survivors through use of VISIA-CA technology and patient reported outcome measures. This study will allow us to collect data and identify the trend (if any) for a future larger study. Patients who consent for participation are given a baseline survey to assess self-reported quality of life, perception of skin quality, and self-image prior to initiation of AI. Patients also receive baseline skin measurement with the VISIA-CA device and facial skin photography. Baseline skincare regimen is documented. Any patients on prescription tretinoin products at time of baseline assessment are excluded from the study. Patients return 6 months after initiation of AI for follow-up surveys, updated VISIA-CA measurement, and facial skin photography. Patients then meet with a Mayo Clinic Cosmetic Center aesthetician for skincare intervention with recommended topical treatments including daily facial cleanser, exfoliator, toner, hydrating crème, and retinol-based product. Patients return for additional visits with updated survey, VISIA-CA measurement, and facial skin photography at 1 month, 3 months, and 6 months after skincare intervention. Patients are asked to complete skincare compliance diary to document adherence on a weekly basis. Eligibility Criteria: Post-menopausal patients with newly diagnosed ER-positive BC at Mayo Clinic Florida are identified for participation in the study prior to beginning AI therapy. Specific Aims: 1.) Evaluate the incidence and severity of skin changes after initiation of AI therapy in BC survivors through use of Canfield Sciences VISIA-CA technology, facial skin photography, and validated patient reported outcome measures. 2.) Assess for objective improvements in skin quality measurements after skincare intervention including a retinol-based product Statistical Methods: Continuous variables will be summarized as mean (standard deviation) or median (range) and categorical variables will be reported as frequency (percentage). The changes of skin measurement and patient reported outcome measurements will be calculated and summarized for the following time frames: 1) from initiation of AI therapy to 26 weeks after 2) from the initiation of skincare intervention and 4 weeks, 12 weeks, and 26 weeks after. Appropriate statistical plots will be used to illustrate the change. Target Accrual: 50 patients.

Eligibility criteria for using menopausal hormone therapy in breast cancer survivors: a safety report based on a systematic review and meta-analysis.

Menopause hormone therapy (MHT) effectively alleviates menopausal symptoms. However, it is generally not recommended for breast cancer survivors, although the scientific evidence is scarce. This study aimed to establish eligibility criteria for use of the MHT in breast cancer survivors based on a systematic review and meta-analysis of the literature. We conducted exhaustive literature searches until June 2022 in MEDLINE, The Cochrane Library, and EMBASE, using a tailored strategy with a combination of controlled vocabulary and search terms related to breast cancer survivors and MHT. We followed the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines and assessed the risk of bias using the Cochrane and Risk of Bias in Non-randomized Studies - of Interventions tools. The quality of the evidence was graded according to grading quality of evidence and strength of recommendations criteria (A, high; B, moderate; C, low; and D, very low). We categorized MHT use into four levels: category 1 (no restrictions on use), category 2 (the benefits outweigh the risks), category 3 (the risks generally outweigh the benefits), and category 4 (MHT should not be used). A total of 12 studies met the eligibility criteria. Analysis of the three randomized clinical trials using combined MHT or tibolone revealed no significant differences concerning tumor recurrence (relative risk [RR], 1.46; 95% CI, 0.99-2.24). A combined analysis of randomized clinical trials, prospective, and retrospective trials found no elevated risk of recurrence (RR, 0.85; 95% CI, 0.54-1.33) or death (RR, 0.91; 95% CI, 0.38-2.19). The eligibility criteria for patients with hormone receptor (HR)-positive tumors fell into categories 3B and 3C for combined MHT or estrogen alone and 4A for tibolone. For HR-negative tumors, the category was 2B and 2C. Our findings suggest that MHT could be a viable treatment alternative for breast cancer survivors experiencing menopausal symptoms, especially those with HR-negative tumors. Personalized management is recommended for each peri/postmenopausal woman facing a diminished quality of life because of menopause symptoms. Further randomized trials are needed before considering changes to current standards of care.

Acute Myeloid Leukemia Post Cytotoxic Therapy in Breast Cancer Survivors-Over 23 Years of Single Center Analysis.

Background: Acute myeloid leukemia post cytotoxic therapy (AML-pCT) among breast cancer (BC) survivors represents a life-threatening complication. This study aims to assess the clinical outcomes of AML-pCT post BC. Methods: An analysis of all AML patients treated at a single hematology center (2000-2023) was performed to select patients with AML-pCT post BC. We applied the 2022 ELN criteria to define the genetic risk. Results: Among 847 AML patients, 28 were diagnosed with AML-pCT following BC. Complex karyotype (CK) occurred in 23.8% of patients. The median overall survival (OS) was 40 months. The survival outcomes were better after allogenic hematopoietic stem cell transplantation (alloHCT) treatment compared to chemotherapy alone (median OS: 47 versus 7 months, p = 0.008). Patients demonstrating CK showed lower survival compared to those without CK (2-year OS: 25.0% versus 66.2%, p = 0.0048). The multivariable Cox proportional hazards regression model indicated that treatment with alloHCT emerged as a significant factor associated with improved OS. The treatment was associated with superior OS (HR = 0.07, 95% CI = 0.01-0.86, p = 0.04). Conclusions: Patients with AML-pCT following BC were characterized with the highest frequency of adverse genetic risk profiles and demonstrated worse survival rates. AlloHCT should be performed as early as possible in such patients. The growing need for studies on inherited cancer susceptibility underscores the importance of close AML-pCT development monitoring in BC survivors.

Dance as Rehabilitation and Therapy For Breast Cancer Survivors in Kuala Lumpur

How can dance become a useful medium for rehabilitation and alternative therapy for post-clinical populations is the primary concern of this paper. This study examines the ways in which dance/movement can purposefully aid breast cancer survivors in promoting health wellbeing, post-treatment. The first group, Candy Girls Breast Cancer Survivors, advocates dance for healing and sustenance of healthy living. The second group, breast cancer survivors from the National Cancer Society Malaysia participated in a series of psychotherapeutic sessions centred around dance activities and explored dance as a promising strategy to integrate mind, body, and emotion. This ethnographic study draws data from observations, participations, and interviews with women who have survived breast cancer and who have actively participated in various dance activities.

Abstract LB_B07: Probability of negative impact on adherence caused by the most frequent side effects of adjuvant endocrine therapy for premenopausal breast cancer in SOFT and TEXT Trials

Abstract Background: Regardless of adjuvant chemotherapy, the addition of ovarian function suppression (OFS) to adjuvant endocrine therapy tamoxifen or exemestane in pre-menopausal women with estrogen receptor (ER)-positive breast cancer cause adverse events may affect adherence. Among the 22 targeted adverse events systematically reported in SOFT and TEXT trials, adverse events commonly experienced in exemestane–OFS group (32.3%) and tamoxifen–OFS group (31.0%), compared with tamoxifen alone group (24.6%). Side effects associated with endocrine therapy cause negative impact on adherence. Early discontinuation of endocrine therapy in 22.5%, 19.3%, and 23.7% of the tamoxifen, tamoxifen–OFS, and exemestane–OFS groups, respectively, in SOFT and TEXT trials. This report is intended to evaluate the possible contribution of the 8 most frequently studied side effects that have negative impact on adherence to hormone therapy in breast cancer. Methods: Calculating the probability of negative impact of most frequent endocrine therapy`s side effects (per SOFT-TEXT trials) on adherence per Leanne Fleming et al quantitative systematic review “The impact of medication side effects on adherence and persistence to hormone therapy in breast cancer survivors” Results: Musculoskeletal/joint pain had the most negative impact on the adherence in tamoxifen, tamoxifen–OFS, and exemestane–OFS groups (56%, 63% and 73%, respectively). Average of negative impact of tamoxifen, tamoxifen–OFS, and exemestane–OFS on adherence is 22%, 25% and 27%) Conclusions: The probability of adherence of using tamoxifen alone seems better than tamoxifen–OFS and exemestane–OFS.

Self-Management About Adjuvant Therapy in Breast Cancer Survivors: A Qualitative Study.

ObjectiveThis study aims to describe the experience and connotations of self-management about adjuvant therapy (AT) in Chinese breast cancer survivors (BCS) and explore possible factors that affect their self-management level.MethodsSemi-structured interviews were conducted in postoperative BCS undergoing AT using a qualitative description method. The conceptual structure and connotations were extracted after researchers collected and coded interview transcripts.ResultsAfter interviewing 29 patients, the conceptual framework of self-management in BCS during AT was optimized with three major themes: medical-related, emotion, and role management. Medical-related management includes AT-related adverse reactions; medical cooperation and knowledge acquisition; recovery and protection of affected limb; medical compliance; body image; sexual function and fertility; healthy lifestyle; catheter daily protection; and AT-related financial burdens. Emotion management includes recognition, prevention, and regulation of negative emotions. Role management consists of three aspects: family role, social role, and work role.ConclusionThe conceptual structure and connotations formed in this study can help researchers to evaluate and intervene in the self-management ability of BCS during AT, so as to formulate the best model of care to improve their quality of life and clinical outcomes.

A randomized phase III, double-blinded, placebo-controlled trial of aspirin as adjuvant therapy for breast cancer (A011502): The Aspirin after Breast Cancer (ABC) Trial

360922 Background: In-vitro and in-vivo evidence suggests that aspirin may have an anti-tumor effect. Multiple epidemiologic studies have reported improved breast cancer survival among regular aspirin users compared to non-users. Pooled data from randomized trials of aspirin for cardiovascular disease have also reported a decreased risk of metastatic cancer among aspirin users. Thus, we conducted a prospective randomized controlled trial to determine the true benefits and risks of adjuvant aspirin therapy for breast cancer survivors. Methods: The primary objective was to compare the effect of 300 mg aspirin daily versus placebo upon invasive disease-free survival (iDFS) in patients with high-risk, HER2-negative breast cancer. Secondary objectives included effects on overall survival, cardiovascular disease, toxicity, and adherence. Eligible participants included patients aged 18-70 diagnosed with a primary invasive HER2-negative breast cancer. If hormone receptor (HR)–positive, tumors needed to be node positive and diagnosed within the past 10 years. If HR negative, tumors could be node positive or T2-4N0 and diagnosed within the past 18 months. Participants were randomly selected (1:1) to aspirin 300 mg versus placebo daily for 5 years in a double-blinded fashion. Stratification factors include HR status (positive vs. negative), body mass index (< or ≥ 30 kg/m2), and stage (II vs. III). Based upon an accrual goal of 2,936 patients to reach 381 iDFS events, the study was estimated to have 80% power to detect HR 0.75. Results: From January 2017 to December 2020, 3,021 participants were enrolled. Treatment arms were well balanced in terms of key characteristics. In November 2021, the Data Safety and Monitoring Board recommended that the trial be unblinded because the stratified hazard ratio had crossed a pre-specified futility boundary. After 191 iDFS events (aspirin: 107, placebo: 84) and median follow-up of 20 months, the stratified hazard ratio comparing aspirin to placebo was 1.27 (z-score: -1.64), which is greater than the pre-specified hazard ratio of futility 1.03 (z-score < -0.192). There was no difference in the frequency of grade 3/4 adverse events by study arm. Compliance was high and similar across arms. Non-protocol use of aspirin/non-steroidal anti-inflammatory drugs was similar across arms and less than 14%, consistent with prior randomized aspirin trials. Updated results on iDFS events will be provided at presentation. Conclusions: In this double-blinded, placebo-controlled, randomized trial, there was no benefit in breast cancer invasive disease-free survival with the addition of 300 mg aspirin daily. Although inflammation may still play a role in cancer progression, aspirin is not recommended for prevention of breast cancer recurrence. Clinical trial information: NCT02927249.

Long-Term Follow-Up of Fractional CO2 Laser Therapy for Genitourinary Syndrome of Menopause in Breast Cancer Survivors.

(1) Background: The objective of this study was to determine the long-term efficacy of fractional CO2 laser therapy in breast cancer survivors. (2) Methods: This was a single-arm study of breast cancer survivors. Participants received three treatments of fractional CO2 laser therapy and returned for a 4 week follow-up. Participants were contacted for follow-up at annual intervals. The Vaginal Assessment Scale (VAS), the Female Sexual Function Index (FSFI), the Female Sexual Distress Scare Revised (FSDS-R), the Urinary Distress Inventory (UDI), and adverse events were collected and reported for the two-year follow-up. The changes in scores were compared between the four-week and two-year and the one-year and two-year follow-ups using paired t-tests. (3) Results: In total, 67 BC survivors were enrolled, 59 completed treatments and the four week follow-up, 39 participated in the one-year follow-up, and 33 participated in the two-year follow-up. After initial improvement in the VAS from baseline to the four week follow-up, there was no statistically significant difference in the VAS score (mean Δ 0.23; 95% CI [−0.05, 0.51], p = 0.150) between the four week follow-up and the two-year follow-up. At the two-year follow-up, the FSFI and FSDS-R scores remained improved from baseline and there was no statistically significant change in the FSFI score (mean Δ −0.83; 95% CI [−3.07, 2.38] p = 0.794) or the FSDS-R score (mean Δ −2.85; 95% CI [−1.88, 7.59] p = 0.227) from the one to two-year follow-up. The UDI scores approached baseline at the two-year follow-up; however, the change between the one- and two-year follow-ups was not statistically significant (mean Δ 4.76; 95% CI [−1.89, 11.41], p = 0.15). (4) Conclusions: Breast cancer survivors treated with fractional CO2 laser therapy have sustained improvement in sexual function two years after treatment completion, suggesting potential long-term benefit.

Use of Moisturizers and Lubricants for Vulvovaginal Atrophy.

The estrogen decrease in postmenopausal women results in functional and anatomical changes in the genitourinary tract. The most prevalent and bothersome symptoms are vaginal dryness, dyspareunia, and reduced lubrication, which can significantly affect the quality of life of these women, principally those who are sexually active. Hormonal therapy with local estrogens is generally considered the “gold standard.” However, there are cases in which there are clinical concerns about its use or women opt for non-hormonal options. Thus, safe and effective non-hormonal options are needed to improve symptoms in these women. Moisturizers and lubricants are first-line therapy for breast cancer survivors.

Evaluating chronotypically tailored light therapy for breast cancer survivors: Preliminary findings on fatigue and disrupted sleep

ABSTRACT More than one-third of cancer survivors experience significant residual symptoms after treatment completion. Fatigue and sleep disruption often co-occur and exacerbate each other. The purpose of this preliminary analysis was to examine the effect of a chronotypically tailored light therapy on fatigue and sleep disruption in female survivors 1–3 years post-completion of chemotherapy and/or radiation for stage I to III breast cancer. The data for this analysis were collected as part of an ongoing two-group randomized controlled trial (NCT03304587). Participants were randomized to receive either bright blue-green light (experimental) or dim red light (control). Light therapy was self-administered using a light visor cap at home. Both groups received 30-min daily light therapy for 14 consecutive days either between 19:00 and 20:00 h (for morning chronotypes) or within 30 min of waking in the morning (for evening chronotypes). Fatigue and sleep quality were self-reported using the Patient-Reported Outcomes Measurement Information System (PROMIS)-Fatigue, PROMIS-Sleep Disturbance, Pittsburgh Sleep Quality Index, and a daily log before (pre-test) and following the light intervention (post-test). Linear mixed model analysis or generalized estimating equations examined group difference overtime adjusting for pre-test scores. No between-group differences were found. However, after adjusting for the baseline fatigue, the experimental group reported significant decreases in fatigue (p < .001) and sleep disturbance (p = .024) overtime. The experimental group also reported significantly better subjective sleep quality after 14 d of light therapy (p = .017). Positive trends in sleep latency, sleep duration, night-time awakenings, and early morning awakenings were also observed. Unexpectedly, sleep disturbance significantly decreased in the control group (p = .030). Those who received dim light control reported significantly shorter sleep latency (p = .002), longer total sleep time (p = .042), and greater habitual sleep efficiency (p = .042). These findings suggest that bright light therapy significantly improved post-treatment fatigue and subjective sleep quality in breast cancer survivors. Although it remains to be confirmed, the findings additionally show unexpected benefits of dim light on sleep. Properly timed light exposure may optimize the therapeutic effect and can be the key for successful light therapy. How the administration timing coupled with wavelengths (short vs. long) and intensity of light affecting fatigue and disrupted sleep requires further investigation.

Safety of systemic hormone replacement therapy in breast cancer survivors: a systematic review and meta-analysis.

Symptoms of treatment-induced menopause negatively affect quality of life and adherence to endocrine therapy of breast cancer (BC) survivors. Nevertheless, the use of systemic hormone replacement therapy (HRT) to mitigate these symptoms may be associated with an increased risk of disease recurrence in these patients. This systematic review and meta-analysis aimed to assess the safety of systemic HRT on risk of disease recurrence in BC survivors. A systematic search of PubMed up to April 20, 2021 was conducted to identify randomized controlled trials (RCTs) that investigated the risk of disease recurrence with the use of HRT in BC survivors. A random-effect model was applied to calculate the risk of recurrence, reported as pooled hazard ratio (HR) with 95% confidence intervals (CI). A subgroup analysis was performed to estimate the risk of recurrence according to hormone receptor status. Four RCTs were included in the meta-analysis (n = 4050 patients). Overall, 2022 patients were randomized to receive HRT (estrogen/progestogen combination or tibolone) and 2023 to the control group with placebo or no HRT. HRT significantly increased the risk of BC recurrence compared to placebo(HR 1.46, 95% CI 1.12-1.91, p = 0.006). At the subgroup analysis, the risk of BC recurrence with the use of HRT was significantly increased in patients with hormone receptor-positive disease (HR 1.8, 95% CI 1.15-2.82, p = 0.010) but not in those with hormone receptor-negative tumors (HR 1.19, 95% CI 0.80-1.77, p = 0.390). Use of HRT was associated with a detrimental prognostic effect in BC survivors, particularly in those with hormone receptor-positive disease. Alternative interventions to mitigate menopause-related symptoms should be proposed.

Safety of using hormone replacement therapy in breast cancer survivors: A systematic review and metanalysis.

12067 Background: Improvements in breast cancer (BC) care have led to increased survival of patients; hence, more attention to long-term treatment-related adverse events and quality of life (QoL) is required. Symptoms of spontaneous and treatment-induced menopause significantly affect the QoL and adherence to endocrine therapy among BC survivors, with potential negative implications on outcome. Use of systemic hormone replacement therapy (HRT) to mitigate menopause-associated symptoms is not recommended to reduce the burden of these side effects being historically associated with an increased risk of disease recurrence. This systematic review and metanalysis aimed to estimate the effect of HRT on risk of disease recurrence in BC survivors. Methods: A systematic search of Pubmed and Embase libraries up to January 15, 2021, was conducted in order to identify randomized controlled trials (RCTs) investigating the risk of disease recurrence with the use of HRT in BC survivors. We used the random-effect model to calculate the overall risk of recurrence, reported as pooled hazard ratio (HR) with 95% confidence intervals (CI). Moreover, we performed a subgroup analysis to estimate the risk of recurrence according to hormone receptor status. The Higgins I2 index was computed to assess the heterogeneity between studies. The likelihood of publication bias was assessed by Egger’s test. Results: Four RCTs were found and three were included in the metanalysis (n = 3.973 patients); one study (n = 100 patients) was excluded due to the impossibility to extract the HR for disease recurrence. Overall, 1.990 patients were randomized to receive HRT (estrogen-progesteron combination or tibolone), while 1.983 patients were included in control groups (placebo or no HRT). As compared to control group, HRT significantly increased the risk of BC recurrence (HR 1.49, 95% CI 1.15-1.93, p = 0.002). The heterogeneity between the studies was low (39%, p = 0.194), and no publication bias was found ( p = 0.537). Two studies reported the HR according to hormone receptor status. At the subgroups analysis, the risk of BC recurrence with the use of HRT was significantly increased in hormone receptor-positive patients (HR 1.8, 95% CI 1.15-2.82, p = 0.010) but not in those with hormone receptor-negative tumors (HR 1.25, 95% CI 0.83-1.88, p = 0.290). Conclusions: Use of HRT significantly increases the risk of recurrence in BC survivors, particularly in those with hormone receptor-positive disease. Therefore, this approach remains contraindicated in this setting. Alternative interventions to mitigate menopause-related symptoms should be proposed to these patients.

Importance of Physical Therapy in Breast Cancer Survivors

Women diagnosed with breast cancer have had a significant increase in life expectancy in recent years. However, many of these women are living with chronic complications resulting from treatment. It is common during and after the treatment of breast cancer, particularly at the trunk and upper limb (pain, movement disorders, among others). Physical therapy may play an important role in the immediate and late postoperative period of breast cancer surgery where it can be considered one of the main preventive agents for disorders after surgery. Physical therapy is considered an effective intervention for pain control, postural realignment and recovery of functional autonomy and is important at all stages of treatment, and helps overcome the side effects of breast cancer treatment.

Fractional CO2 laser therapy for genitourinary syndrome of menopause for breast cancer survivors.

Fractional CO2 laser therapy is an emerging treatment for genitourinary syndrome of menopause (GSM). The objective of this study was to determine the feasibility and preliminary efficacy of fractional CO2 laser therapy in breast cancer survivors. This was a single arm feasibility study of breast cancer survivors with dyspareunia and/or vaginal dryness. Participants received three treatments of fractional CO2 laser therapy at 30-day intervals and returned for a 1-month follow-up. Feasibility was defined as treatment completion without serious adverse events (SAE) in 80% of patients. We collected data on the Vaginal Assessment Scale (VAS), the Female Sexual Function Index (FSFI), the Urinary Distress Index (UDI), and SAE. A total of 64 patients participated in the study. The majority of women had Estrogen receptor/Progesteronereceptor (ER/PR)positive/Her2neu negative (n = 37; 63%), stage I (n = 32, 54%) or II (n = 19, 32%) breast cancer. Most were receiving endocrine therapy (n = 54, 92%), most commonly aromatase inhibitors (AI; n = 40, 68%). Fifty-nine (88.1%) of those enrolled completed all treatments according to protocol with no reported SAE. No patient withdrew due to SAE. The scores of the VAS (mean Δ - 0.99; 95% CI [- 1.19, - 0.79], p < 0.001)), FSFI (mean Δ 9.67; 95% CI [7.27, 12.1], p < 0.001), and UDI (mean Δ - 8.85; 95% CI [- 12.75, - 4.75], p < 0.001)) improved from baseline to follow-up. Fractional CO2 laser treatment for breast cancer survivors is feasible and appears to reduce GSM symptoms across treatment and follow-up.

Acceptance and commitment therapy for breast cancer survivors with fear of cancer recurrence: A 3-arm pilot randomized controlled trial.

Fear of cancer recurrence (FCR) has a profound negative impact on quality of life (QOL) for many cancer survivors. Breast cancersurvivors (BCS) are particularly vulnerable, with up to 70% reporting clinically significant FCR. To the authors' knowledge, evidence-based interventions for managing FCR are limited. Acceptance and commitment therapy (ACT) promotes psychological flexibility in managing life's stressors. The current study examined the feasibility and preliminary efficacy of group-based ACT for FCR in BCS. Post-treatment BCS (91 patients with stage I-III disease) with clinical FCR randomly were assigned to ACT (6weekly 2-hour group sessions), survivorship education (SE; 6weekly 2-hour group sessions), or enhanced usual care (EUC; one30-minute group coaching session with survivorship readings). FCR severity (primary outcome) and avoidant coping, anxiety, post-traumatic stress, depression, QOL, and other FCR-related variables (secondary outcomes) were assessed at baseline (T1), after the intervention (T2), 1month after the intervention (T3), and 6months after the intervention (T4) using intent-to-treat analysis. Satisfactory recruitment (43.8%) and retention (94.5%) rates demonstrated feasibility. Although each arm demonstrated within-group reductions in FCR severity over time, only ACT produced significant reductions at each time point compared with baseline, with between-group differences at T4 substantially favoring ACT over SE (Cohen d for effect sizes, 0.80; P<.001) and EUC (Cohen d, 0.61; P<.01). For 10 of 12 secondary outcomes, only ACT produced significant within-group reductions across all time points. By T4, significant moderate to large between-group comparisons favored ACT over SE and EUC with regard to avoidant coping, anxiety, depression, QOL, and FCR-related psychological distress. Group-based ACT is a feasible and promising treatment for FCR and associated outcomes in BCS that warrants testing in larger, fully powered trials.

Cost-utility, cost-effectiveness, and budget impact of Internet-based cognitive behavioral therapy for breast cancer survivors with treatment-induced menopausal symptoms

PurposeInternet-based cognitive behavioral therapy (iCBT), with and without therapist support, is effective in reducing treatment-induced menopausal symptoms and perceived impact of hot flushes and night sweats (HF/NS) in breast cancer survivors. The aim of the current study was to evaluate the cost-utility, cost-effectiveness, and budget impact of both iCBT formats compared to a waiting list control group from the Dutch healthcare perspective.MethodsA Markov model was constructed with a 5-year time horizon. Costs and health outcomes were measured alongside a randomized controlled clinical trial and included quality-adjusted life years (QALYs), overall levels of menopausal symptoms, and perceived impact of HF/NS. Uncertainty was examined using probabilistic and deterministic sensitivity analyses, together with a scenario analysis incorporating a different perspective.ResultsiCBT was slightly more expensive than the waiting list control, but also more effective, resulting in incremental cost-utility ratios of €23,331/QALY and €11,277/QALY for the guided and self-managed formats, respectively. A significant reduction in overall levels of menopausal symptoms or perceived impact of HF/NS resulted in incremental costs between €1460 and €1525 for the guided and €500–€753 for the self-managed format. The estimated annual budget impact for the Netherlands was €192,990 for the guided and €74,592 for the self-managed format.ConclusionBased on the current trial data, the results indicate that both guided and self-managed iCBT are cost-effective with a willingness-to-pay threshold of well below €30,000/QALY. Additionally, self-managed iCBT is the most cost-effective strategy and has a lower impact on healthcare budgets.

Fractional CO2 laser therapy for genitourinary syndrome of menopause (GSM) in survivors of breast cancer (BC).

202 Background: Fractional CO2 laser therapy is an emerging treatment for GSM. The objective of this study was to determine the feasibility, tolerability and preliminary efficacy of fractional CO2 laser therapy in BC survivors. Methods: This was a single arm feasibility study of BC survivors with dyspareunia and/or vaginal dryness. Participants received three treatments with office-based fractional CO2 laser on at least 30 day intervals and returned for a one-month follow-up. Feasibility was defined as treatment completion without serious adverse events (SAE) in a minimum of 80% of patients. Primary efficacy was evaluated using the mean change (∆) in the score on the Vaginal Assessment Scale (VAS). Secondary efficacy endpoints included mean ∆ in scores on the Female Sexual Function Index (FSFI) and Urogenital Distress Inventory (UDI). Descriptive statistics (means and 95% confidence intervals (CI) for continuous variables and proportions for categorical variables) were used. Results: The study is ongoing with 65 patients enrolled. To date, 37 patients have completed all study treatments and follow-up. Median age for those who have completed treatment was 57 years (range 34-72). Most were ER/PR positive (78%) and Her 2 negative (81%) with stage I (43%) or II (41%) BC. Ninety-five percent were receiving endocrine therapy, most commonly aromatase inhibitors (73%). No SAEs were reported in the 37 patients who have completed study treatments and their outcomes are as follows. Based on the VAS, 78% reported moderate-severe dyspareunia and 89% reported moderate-severe vaginal dryness at baseline. At follow up, 28% reported moderate-severe dyspareunia and 28% reported moderate-severe vaginal dryness. The VAS score improved from baseline to follow up (mean ∆ 4.1; 95% CI [3.1, 5.1]). Similarly, the FSFI score improved (mean ∆ -10.0; 95% CI [-13.2, -6.9]) and the UDI score improved (mean ∆ -5.7; 95% CI [-10.1, -1.3]). Final efficacy analysis will be reported once all patients have completed all time points. Conclusions: Fractional CO2 laser treatment is feasible and tolerable in BC survivors and may reduce symptom burden from GSM. A randomized controlled trial with sham laser is currently in development. Clinical trial information: NCT03307044.

Providers' Perspectives on Adherence to Hormonal Therapy in Breast Cancer Survivors. Is there a Role for the Digital Health Feedback System?

Despite the benefits of hormonal therapy (HT) adherence remains suboptimal in ER positive breast cancer patients. Medication adherence is challenging to assess and tends to be overestimated. The Digital Health Feedback System (DHFS) consists of an ingestible sensor attached to a pill that sends intake date and time to a smart phone or computer. Patients can share this information with health care providers and other persons. The DHFS can also send reminders. This mixed methods study examined providers' perceptions of HT medication adherence. The potential role of the DHFS in enhancing medication tracking and adherence was also explored. We conducted semi-structured interviews with key informants (N=10). Questions examined perceptions about adherence barriers and facilitators, challenges tracking adherence, and views on the DHFS. Findings informed the development of a survey that was administered online (N=19). Providers emphasized the importance of fostering open and trustful communication around adherence. The most mentioned challenges to assessing adherence were the patient not disclosing discontinuation immediately (78.9%) and over-reporting adherence (57.9%). The perceived potential benefits of DHFS were the ability to track adherence better (94.7%) and reminders to take the medication (68.4%). Safety to ingest a sensor was as a major perceived barrier (8 4.2%). Interventions that target providers and doctor-patient communication are warranted to enhance adherence and reduce communication delays around HT discontinuation. DHFS has the potential to enhance HT adherence by directly targeting barriers. Future studies should also examine the feasibility of adopting the DHFS with cancer patients.
