Effects of Adjuvant Endocrine Therapy-Specific Perceptions on Response to a Behavioral Intervention for Adjuvant Endocrine Therapy Adherence in Patients With Breast Cancer. JCO Oncol Pract 2024:OP2400316. [PMID: 39137385 DOI: 10.1200/op.24.00316] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/11/2024] [Revised: 06/07/2024] [Accepted: 07/08/2024] [Indexed: 08/15/2024] Open
Abstract
PURPOSE Adjuvant endocrine therapy (AET) is a life-saving medication for patients with hormone-sensitive breast cancer, yet many struggle with adherence, warranting behavioral intervention. In our recent trial, participation in a group cognitive behavioral intervention (STRIDE) for symptom management and adherence was associated with improvements in symptom distress, coping, quality of life, and mood. We now explore whether baseline patient- and medication-specific factors-which may be modifiable by clinician-led discussions-moderated the effect of STRIDE on adherence rates. METHODS From October 2019 to June 2021, 100 patients with early-stage breast cancer reporting AET-related distress were enrolled and randomly assigned to STRIDE or a medication monitoring (MM) control group. All patients stored their AET in electronic pill bottles to track objective adherence. Patients also self-reported their adherence on the Medication Adherence Report Scale-5 and their perceptions of AET on the Cancer Therapy Satisfaction Questionnaire at baseline. We conducted hierarchical linear modeling to test moderators of intervention effects on objective adherence rates. We report the time × group × moderator effects. RESULTS Among patients reporting greater perceived difficulties with AET adherence at baseline, STRIDE participants had higher adherence rates over time compared with MM (b = -13.80; SE = 4.56; P < .01). Patients with greater expectations of therapeutic benefit from AET also had improved adherence rates if they were assigned to STRIDE, versus MM (b = 0.25; SE = 0.10; P = .01). Patients who perceived taking AET as convenient and had been taking their AET for less time had higher adherence rates in STRIDE, versus MM. CONCLUSION The current study identified patient- and medication-specific factors that may augment AET adherence interventions and may be modifiable through clinician-led discussions, such as perceptions of adherence problems, therapeutic efficacy, and convenience of AET.

Abstract
PURPOSE Adjuvant endocrine therapy has a vital role in reducing breast cancer mortality. The beliefs in adjuvant endocrine therapy is a very important factor in the medication adherence of breast cancer survivors. Therefore, it is necessary to develop a standardized scale for assessment of adjuvant endocrine therapy. The purpose of this study was to identify the attributes of adjuvant endocrine therapy beliefs, and to evaluate adjuvant endocrine therapy beliefs scale psychometric properties. METHODS A hybrid model was applied to identify the concept of adjuvant endocrine therapy beliefs and measurement question were developed by the scale development process. Statistical analysis using validity analysis and Rasch analysis based on item response theory were performed. A total of 228 breast cancer survivors in South Korea participated in the study. RESULTS The finally developed adjuvant endocrine therapy beliefs scale consisted of 22 items. The items extracted by 4 factors explained 59.72% of the total variance. The model fit showed an acceptable level. The adjuvant endocrine therapy beliefs scale was excellent in convergent and discriminant validity with reliability. CONCLUSION This scale is expected to be practical and useful in identifying adjuvant endocrine therapy beliefs and developing intervention strategies to promote adjuvant endocrine therapy adherence. In addition, continuous education and support should be accompanied so that breast cancer survivors can maintain positive beliefs in adjuvant endocrine therapy adherence.

Abstract
PURPOSE Adjuvant endocrine therapy (AET) reduces breast cancer morbidity and mortality; however, adherence is suboptimal. Interventions exist, yet few have improved adherence. Patient characteristics may alter uptake of an intervention to boost adherence. We examined moderators of the effect of a virtual intervention (STRIDE; #NCT03837496) on AET adherence after breast cancer. METHODS At a large academic medical center, patients taking AET (N = 100; Mage = 56.1, 91% White) were randomized to receive STRIDE versus medication monitoring. All stored their medication in digital pill bottles (MEMS Caps) which captured objective adherence. Participants self-reported adherence (Medication Adherence Report Scale) at 12 weeks post-baseline. Moderators included age, anxiety, and depressive symptoms (Hospital Anxiety and Depression Scale), AET-related symptom distress (Breast Cancer Prevention Trial Symptom Scale), and AET-specific concerns (Beliefs about Medications Questionnaire). We used hierarchical linear modeling (time × condition × moderator) and multiple regression (condition × moderator) to test the interaction effects on adherence. RESULTS Age (B = 0.05, SE = 0.02, p = 0.003) and AET-related symptom distress (B = -0.04, SE = 0.02, p = 0.02) moderated condition effect on self-reported adherence while anxiety (B = -1.20, SE = 0.53, p = 0.03) and depressive symptoms (B = -1.65, SE = 0.65, p = 0.01) moderated objective adherence effects. AET-specific concerns approached significance (B = 0.91, SE = 0.57, p = 0.12). Participants who received STRIDE and were older or presented with lower anxiety and depressive symptoms or AET-related symptom distress exhibited improved adherence. Post hoc analyses revealed high correlations among most moderators. CONCLUSIONS A subgroup of patients who received STRIDE exhibited improvements in AET adherence. The interrelatedness of moderators suggests an underlying profile of patients with lower symptom burden who benefitted most from the intervention. STUDY REGISTRATION NCT03837496.

Abstract
PURPOSE Adjuvant endocrine therapy (AET) reduces breast cancer morbidity and mortality, yet women often report suboptimal adherence. Though correlates of AET adherence are well-documented, few studies examine the relative importance of multi-level factors associated with adherence. The aim of this study was to identify factors most strongly associated with AET adherence in women with breast cancer. METHODS Between 10/2019 and 6/2021, women (N = 100) with non-metastatic, hormone receptor-positive breast cancer, taking AET who reported AET-related distress enrolled into a clinical trial. Participants completed baseline measures, including the Medication Adherence Rating Scale-5, sociodemographics, and validated measures of anxiety, depression, medication-taking self-efficacy, social support, and treatment satisfaction. We created a latent factor and tested associations between sociodemographic, medical, and psychosocial characteristics and adherence. Associated predictors (p < .10) were entered into a structural model, which was corroborated via multivariate regression modeling. RESULTS A four-indicator latent adherence factor demonstrated good model fit. Participants (Mage = 56.1 years, 91% White) who were unemployed (B = 0.27, SE = 0.13, p = .046) and reported greater treatment convenience (B = 0.01, SE = 0.01, p = .046) reported greater adherence. Scores of participants who reported greater medication-taking self-efficacy (p = .097) and social support (p = .062) approached better adherence. Greater medication-taking self-efficacy (B = 0.08, SE = 0.02, p < .001) and being unemployed (B = 0.28, SE = .14, p = .042) were most strongly associated with greater adherence, independent of other predictors. Multivariate modeling confirmed similar findings. CONCLUSIONS Medication-taking self-efficacy and employment status were associated with AET adherence above other related factors. IMPLICATIONS FOR CANCER SURVIVORS Enhancing patients' confidence in their ability to take AET for breast cancer may represent an important intervention target to boost adherence.

Abstract
This observational, cross-sectional study conducted at the University Hospital Centre Zagreb (UHC Zagreb) aimed to explore patients' beliefs about adjuvant endocrine therapy (AET) as well as their association with non-adherence and sociodemographic and clinical factors. Out of 420 early breast cancer (BC) patients included in the study, 79.5 % perceived AET necessary and important for their health, as measured by the Belief About Medicines Questionnaire (BMQ), with the mean necessity score (20.4 ± 3.68) significantly higher than the mean concerns score (13 ± 4.81) (p < 0.001). Based on the Medication Adherence Report Scale (MARS-5), 44.4 % (n = 182) of the participants were non-adherers, out of which 63.2 % (n = 115) were unintentional and 36.8 % (n = 67) intentional non-adherers. Significantly higher concern beliefs were found among patients that were younger (p < 0.001), employed (p < 0.001), intentionally non-adherent to AET (p = 0.006), had a lower body-mass index (p = 0.005) and a higher level of education (p < 0.001), were premenopausal at the time of diagnosis (p < 0.001), taking tamoxifen treatment (p = 0.05) and receiving ovarian suppression (p < 0.001). Younger patients should be recognized as being at risk of non-adherence as they hold greater concern beliefs about medicines.

Abstract
PURPOSE Adherence and persistence to adjuvant hormone therapy (AHT) are seldom maintained among early-stage hormone receptor-positive breast cancer (BC) survivors, despite the significant clinical benefits of long-term AHT. As the factors influencing adherence to AHT remain unclear, this study aimed to comprehensively identify such factors and classify them into specific dimensions. METHODS PubMed, Cochrane Library, Embase, PsycINFO, and CINAHL were searched for qualified articles. The search mainly focused on three components: early-stage (0-III) BC, oral AHT administration, and adherence to AHT, with keywords derived from MeSH and entry terms. The factors identified were then classified into six categories based on a modified WHO multidimensional model. RESULTS Overall, 146 studies were included; the median sample size was 651 (range, 31-40,009), and the mean age of the population was 61.5 years (standard deviation, 8.3 years). Patient- and therapy-related factors were the most frequently investigated factors. Necessity/concern beliefs and self-efficacy among patient-related factors were consistently related to better adherence than depression. Although drug side effects and medication use cannot be modified easily, a refined prescription strategy for the initiation and switching of AHT is likely to increase adherence levels. CONCLUSION An effective psychological program that encourages positive views and beliefs about medication and management strategies for each therapy may be necessary to improve adherence to AHT. Social support and a sense of belonging can be enhanced through community participation and social media for better adherence to AHT. Patient-centered communication and appropriate recommendations by physicians may be attributable to better adherence outcomes. Findings from systematically organized factors that influence adherence to AHT may contribute to the establishment of intervention strategies to benefit patients with early-stage BC to achieve optimal health.

Abstract
OBJECTIVE Non-adherence to adjuvant endocrine therapy (AET) for breast cancer leads to increased recurrence and mortality risk and healthcare costs. Evidence on feasible, effective AET adherence interventions is scarce. This paper describes the systematic adaptation of the cost-effective adherence improving self-management strategy (AIMS) for patients with HIV to AET for women after breast cancer treatment. METHODS We followed the intervention mapping protocol for adapting interventions by conducting a needs assessment, reviewing target behaviours and determinants, reassessing behaviour change methods and adapting programme content. Therefore, we performed a literature review, consulted behavioural theory and organised nine advisory board meetings with patients and healthcare professionals. RESULTS Non-adherence occurs frequently among AET users. Compared to HIV treatment, AET is less effective, and AET side effects are more burdensome. This drives AET treatment discontinuation. However, the key determinants of non-adherence are largely similar to HIV treatment (e.g. motivation, self-regulation and patient-provider relationship); therefore, most strategies in AIMS-HIV also seem suitable for AIMS-AET. Modifications were required, however, regarding supporting patients with coping with side effects and sustaining treatment motivation. CONCLUSION AIMS seems to be a suitable framework for adherence self-management across conditions and treatments. Intervention mapping offered a transparent, systematic approach to adapting AIMS-HIV to AET.

Abstract
IMPORTANCE Though adjuvant endocrine therapy (AET) has proven efficacy in treating hormone receptor-positive (HR-positive) breast cancer, patient adherence to AET and continuation of treatment as recommended by guidelines remain suboptimal, especially for low-income patients. OBJECTIVE To quantify timelines for initiating AET and assess their association with short- and long-term adherence and continuation of AET in low-income women with breast cancer. DESIGN, SETTING, AND PARTICIPANTS This population-based retrospective cohort study included women younger than 65 years diagnosed with first primary HR-positive breast cancer between January 1, 2007, and December 31, 2013, followed up for 5 years after the first use of AET through December 2018, and identified from the linked Missouri Cancer Registry and Medicaid claims data set. EXPOSURES Time to initiation (TTI) as days from the date of last treatment (surgery, radiotherapy, or chemotherapy) to the first date of AET prescription fill. MAIN OUTCOMES AND MEASURES The main outcomes were adherence to AET as medication possession ratio of 80% or greater and continuation of AET as no gap in medication supply for at least 90 days. Odds ratios (ORs) of adherence and continuation over 1 to 5 years were estimated using logistic regression adjusted for demographic, clinical, and neighborhood variables. Analyses were performed between September 1, 2020, and May 31, 2022. RESULTS Among 1711 patients, median TTI was 53 (IQR, 26-117) days. A total of 1029 patients (60.1%) were aged 50 to 64 years old, 1270 (74.2%) were non-Hispanic White, and 1133 (66.2%) were unmarried. In the first year after initiation, 1317 (77.0%) were adherent and 1015 (59.3%) continued AET. Over the full 5 years, 376 (22.0%) were adherent and 409 (23.9%) continued AET. Longer TTI was significantly associated with poorer adherence at every year, with an OR of 0.97 (95% CI, 0.95-0.99) for 1-year adherence and an OR of 0.94 (95% CI, 0.90-0.97) for 5-year adherence per 1-month increase in TTI. Longer TTI was also associated with lower odds of short-term, but not long-term, continuation (OR, 0.97 [95% CI, 0.95-0.99] for 1-year continuation and 0.98 [95% CI, 0.96-0.99] for 2-year continuation). CONCLUSIONS AND RELEVANCE In this cohort study, longer time to AET initiation was associated with lower odds of short-term and long-term adherence to AET in Medicaid-insured patients with breast cancer. Therefore, early interventions targeting treatment initiation timelines may positively impact adherence throughout the course of treatment and, therefore, outcomes.

Abstract
Introducción: La adherencia terapéutica es un aspecto clave en el éxito del tratamiento en oncología, sin embargo, su medición es un reto dentro del sistema de salud. Asimismo, no se tienen escalas especificas validas o construidas para evaluar la adherencia en pacientes con cáncer de mama. Objetivo: Determinar las propiedades psicométricas de la Escala de Adherencia Terapéutica al Cáncer de Mama (EAT-CaMa). Método: Se empleó un diseño no experimental, instrumental con un muestreo no probabilístico. Se incluyeron 189 participantes con diagnóstico de CaMa entre 21 y 84 años. Análisis estadísticos: Se realizó un análisis factorial exploratorio y consistencia interna. Resultados: La EATCaMa de 27 reactivos, obtuvo una consistencia interna global α= 0,81 y una varianza explicada del 64%. Se identificaron factores de autoeficacia y comunicación médico paciente, así como varios indicadores. Conclusión: El EAT-CaMa es un instrumento breve, válido y confiable para la evaluación multidimensional de la adherencia al tratamiento en población con CaMa. La estructura factorial identificada corrobora componentes reportados en la literatura y clínicamente relevantes. Se recomienda su uso en la atención clínica (inicio y seguimiento del tratamiento) y en investigación.

Abstract
Purpose Aromatase inhibitors (AIs) are widely prescribed for postmenopausal women with breast cancer and are known to cause musculoskeletal pain. This study aimed to identify factors associated with AI continuation intention among breast cancer survivors (BCS). Methods A cross-sectional survey was conducted on 123 BCS (stages I–III), who had been taking AIs for at least 6 weeks. Participants were recruited from a cancer center in Goyang, Korea, from September to November 2019. Descriptive statistics, Welch analysis of variance, Pearson correlation coefficients, and simple linear regression were used for the analysis. Results Beliefs about endocrine therapy was a significant predictor of AI continuation intention (β=.66, p<.001). The majority of participants (87.0%) reported experiencing musculoskeletal pain since taking AIs and the score for the worst pain severity within 24 hours was 5.08±2.80 out of 10. Musculoskeletal pain, however, was not associated with AI continuation intention. Fear of cancer recurrence (FCR) was clinically significant (≥13) for 74.0% of the respondents (mean, 17.62±7.14). Musculoskeletal pain severity and pain interference were significantly associated with FCR (r=.21, p<.05; r=.35, p<.01, respectively). Pain interference was significantly associated with beliefs about endocrine therapy (r=–.18, p<.05). Conclusion AI continuation intention can be modified by reinforcing patients’ beliefs about endocrine therapy. Musculoskeletal pain may have a negative effect on beliefs about endocrine therapy and increase FCR among BCS. Thus, awareness of musculoskeletal pain during AI therapy should be raised and further research is required to develop multidisciplinary pain management strategies and clinical guidelines to reinforce beliefs about endocrine therapy.

Potentially Modifiable Factors Associated with Adherence to Adjuvant Endocrine Therapy among Breast Cancer Survivors: A Systematic Review. Cancers (Basel) 2020; 13:cancers13010107. [PMID: 33561076 PMCID: PMC7794693 DOI: 10.3390/cancers13010107] [Citation(s) in RCA: 27] [Impact Index Per Article: 6.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/21/2020] [Revised: 12/28/2020] [Accepted: 12/29/2020] [Indexed: 01/01/2023] Open
Abstract
Adjuvant endocrine therapy (AET) reduces risk of breast cancer recurrence. However, suboptimal adherence and persistence to AET remain important clinical issues. Understanding factors associated with adherence may help inform efforts to improve use of AET as prescribed. The present systematic review examined potentially modifiable factors associated with adherence to AET in accordance with PRISMA guidelines (PROSPERO registration ID: CRD42019124200). All studies were included, whether factors were significantly associated with adherence or results were null. This review also accounted for the frequency with which a potentially modifiable factor was examined and whether univariate or multivariate models were used. This review also examined whether methodological or sample characteristics were associated with the likelihood of a factor being associated with AET adherence. A total of 68 articles were included. Potentially modifiable factors were grouped into six categories: side effects, attitudes toward AET, psychological factors, healthcare provider-related factors, sociocultural factors, and general/quality of life factors. Side effects were less likely to be associated with adherence in studies with retrospective or cross-sectional than prospective designs. Self-efficacy (psychological factor) and positive decisional balance (attitude toward AET) were the only potentially modifiable factors examined ≥10 times and associated with adherence or persistence ≥75% of the time in both univariate and multivariate models. Self-efficacy and decisional balance (i.e., weight of pros vs. cons) were the potentially modifiable factors most consistently associated with adherence, and hence may be worth focusing on as targets for interventions to improve AET adherence among breast cancer survivors.

Abstract
Patients' beliefs about medications are important predictors of medication adherence; however, the relationship between patient beliefs and adjuvant endocrine therapy (AET) adherence in patients with breast cancer remains unclear. In this study, we aimed to determine the association between patient beliefs and adherence to AET. Self-reported questionnaires covering necessity beliefs (NB), concerns beliefs (CB), and adherence were completed by 210 Korean patients with breast cancer. The rate of nonadherence was determined by calculating necessity-concern (N-C) differentials and attitudinal subgroup analysis. Multivariate logistic regression analysis was performed to determine the independent impact of patient beliefs on nonadherence. Nonadherence (Morisky Medication Adherence Scale < 8) was reported in 74.3% (n = 156) of patients and predicted by a negative balance regarding AET [odds ratio (OR) = 0.89; 95% confidence interval (CI): 0.83-0.96] and strong concerns about AET such as those in the Ambivalent (OR = 5.41; 95% CI: 1.84-15.92) and Skeptical (OR = 3.48, 95% CI: 1.14-10.65) subgroups. Patient beliefs are significantly associated with adherence to AET in Korean patients with breast cancer. NB, CB, and N-C differentials may be useful intervention targets to improve medication adherence.

Pathological profiles and clinical management challenges of breast cancer emerging in young women in Indonesia: a hospital-based study. BMC Womens Health 2019; 19:28. [PMID: 30728000 PMCID: PMC6364389 DOI: 10.1186/s12905-019-0724-3] [Citation(s) in RCA: 20] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/18/2018] [Accepted: 01/23/2019] [Indexed: 12/24/2022] Open
Abstract
BACKGROUND Breast cancer diagnosed at a young age is often associated with aggressive biology, advanced stage, and unfavorable prognosis. The median age of breast cancer diagnosis in Indonesia is younger (48 vs. 68 years-old in Europe) with a relatively higher proportion of patients younger than 40 years old. Although prognosis and outcome of young breast cancer are well studied in developed nations, research evaluating biological characteristics, delivered treatment, and clinical outcomes is very limited in Indonesia. METHODS We analyzed all breast cancer patients who underwent surgery at Dr. Sardjito Hospital, Indonesia, in 2012-2017. Details of pathology profiles, treatment administrated, and outcomes, as well as reproductive factors among patients younger than 40 years old, were collected and analyzed. Kaplan-Meier curve was used to assess conditional survival based on baseline characteristics. RESULTS From the total of 1259 breast cancer patients (median age 51 years), 144 (11.4%) were younger than 40 years old (median age 37 years). Of these young patients, 19 (13.2%) were bilateral and 92 (64%) were diagnosed in advanced stages (stages IIIA-C and IV). Median tumor diameter was 5.5 cm and nodal infiltration was present in 73%. Distant metastasis was found in 16% at the time of diagnosis. Moderate and poor differentiation of tumor were 20.8 and 78.5%, respectively, and lymphovascular invasion was found in 90.3%. Around 40% were hormone receptor-positive, 30.6% human epidermal growth factor receptor 2 positive, and 38.2% triple negative. Patients underwent radical surgery in 121 cases (84%) and breast conserving surgery in 7 cases (4.9%). Adjuvant chemotherapy was administrated in 68% and hormonal therapy in 34%. Progression-free survival was significantly shorter in patients with advanced stage, skin and chest wall involvement (T4), positive lymph node infiltration, positive hormonal receptor, and triple negative subtype (log-rank Mantel-Cox tests, p < 0.05). CONCLUSION We found a high frequency of young breast cancer with biologically more aggressive tumors, late diagnosis, frequent relapse, and poor prognosis. Further actions to improve clinical management and meet psychosocial needs in young breast cancer patients are warranted.
