Current breast cancer (BC) diagnostics include detailed pathological and genetic analysis for biological subtype identification; however, throughout the course of the disease, new alterations determining the progression of the disease or resistance to treatment appear. The tests based on liquid biopsy allow minimally invasive real-time monitoring of tumour-specific alteration during the entire disease treatment. Tumour-specific genetic material fragments occur in bodily fluids, and cell-free nucleic acids are a convenient tool for analysing genetic and epigenetic changes in tumours. Evidence for the diagnostic and prognostic value of epigenetic biomarkers is gradually increasing. Although, up to date, there is limited access to in vitro diagnostic (IVD) epigenetic liquid biopsy-based tests for BC management, the data on the clinical potential of such tests and biomarkers are accumulating rapidly.
Methods
In this review, we focused on research involving cell-free DNA methylation biomarkers in blood serum or plasma samples from BC patients.
Results
Our review systematises data from genome-wide and targeted studies of DNA methylation changes in liquid biopsies from BC patients, aiming to highlight the most critical biomarkers suitable for early BC diagnosis, treatment personalisation and prognosis.
Conclusion
In summary, cell-free DNA methylation biomarkers show strong potential to enhance breast cancer diagnosis, prognosis, and personalised treatment through integrated clinical profiling.
Given the increased risk of cardiac toxicity with higher doses, cardiac sparing is crucial for left-sided breast cancer patients. Deep inspiration breath hold (DIBH) is one approach, but its reproducibility is questioned. This study evaluates the reproducibility of DIBH with an active breathing coordinator (ABC) device, focusing on its dosimetric impact in maintaining consistent cardiac sparing for patients undergoing partial breast irradiation (PBI).
Methods:
Thirty-three patients undergoing PBI with a prescription dose of 30 Gy in five fractions were randomly selected. Each patient was treated with 6 MV photons using volumetric modulated arc therapy (VMAT) with DIBH using an ABC device. Prior to each fraction, kilo-voltage cone beam computed tomography (kV-CBCT) images were acquired to assess inter-fractional heart motion. Contours of the whole heart and left anterior descending artery (LAD) were transferred from the planning CT to CBCTs and back, using rigid alignment and isocentre shifts to represent treatment positions. Agreement between delivered and planned doses assessed DIBH reproducibility.
Results:
Throughout the entire treatment course, changes in mean and maximum cardiac doses were less than 16·4 cGy and 264·8 cGy, respectively. Changes in mean and maximum LAD doses were less than 54·0 cGy and 160·2 cGy, respectively. Overall, the mean cardiac dose increased by 2·4 ± 6·6 cGy, and the maximum by 23·3 ± 58·0 cGy. The mean LAD dose increased by 4·8 ± 18·5 cGy, and the maximum by 17·0 ± 51·0 cGy.
Conclusions:
DIBH can be effectively reproduced with the ABC device, limiting inter-fractional cardiac dose changes.
The World Cancer Research Fund and the American Institute for Cancer Research recommend a plant-based diet to cancer survivors, which may reduce chronic inflammation and excess adiposity associated with worse survival. We investigated associations of plant-based dietary patterns with inflammation biomarkers and body composition in the Pathways Study, in which 3659 women with breast cancer provided validated food frequency questionnaires approximately 2 months after diagnosis. We derived three plant-based diet indices: overall plant-based diet index (PDI), healthful plant-based diet index (hPDI) and unhealthful plant-based diet index (uPDI). We assayed circulating inflammation biomarkers related to systemic inflammation (high-sensitivity C-reactive protein [hsCRP]), pro-inflammatory cytokines (IL-1β, IL-6, IL-8, TNF-α) and anti-inflammatory cytokines (IL-4, IL-10, IL-13). We estimated areas (cm2) of muscle and visceral and subcutaneous adipose tissue (VAT and SAT) from computed tomography scans. Using multivariable linear regression, we calculated the differences in inflammation biomarkers and body composition for each index. Per 10-point increase for each index: hsCRP was significantly lower by 6·9 % (95 % CI 1·6%, 11·8%) for PDI and 9·0 % (95 % CI 4·9%, 12·8%) for hPDI but significantly higher by 5·4 % (95 % CI 0·5%, 10·5%) for uPDI, and VAT was significantly lower by 7·8 cm2 (95 % CI 2·0 cm2, 13·6 cm2) for PDI and 8·6 cm2 (95 % CI 4·1 cm2, 13·2 cm2) for hPDI but significantly higher by 6·2 cm2 (95 % CI 1·3 cm2, 11·1 cm2) for uPDI. No significant associations were observed for other inflammation biomarkers, muscle, or SAT. A plant-based diet, especially a healthful plant-based diet, may be associated with reduced inflammation and visceral adiposity among breast cancer survivors.
Real-world studies provide valuable insights into long-term outcomes across diverse populations. Here, we contextualise recent findings on the association between antipsychotic use and breast cancer risk in women with schizophrenia. We discuss clinical implications and the strengths and limitations of real-world studies in psychiatry. We conclude with future perspectives.
Before COVID-19, breast cancer patients in the UK typically received 15 radiotherapy (RT) fractions over three weeks. During the pandemic, adoption of a 5-fraction treatment prescription and more advanced treatment techniques like surface-guided RT, meant a change in the duration and number of hospital visits for patients accessing treatment. This work sought to understand how breast cancer patients’ time in the RT department has changed, between 2018 and 2023.
Methods:
Appointments for CT simulation, mould room, and RT, from January 2018 to December 2023, were extracted from the Mosaiq® Oncology Management System. Appointments lasting between 5 minutes and 5 hours were analysed. Total visit time was calculated from check-in to completion on the quality checklist.
Results:
In total, 29,523 attendances were analysed over 6 years. Average time spent in the department decreased during the pandemic but has since increased 12·4% above pre-COVID-19 levels. Early morning and late afternoon appointments resulted in the shortest visits, with early afternoon appointments leading to the longest visits. On average, patients spend the longest in the department on a Monday, and the least amount of time on a Friday. Friday was the least common day to start a 15-fraction treatment, whereas Tuesday and Friday were equally uncommon for the 5-fraction regime.
Conclusions:
During the COVID-19 pandemic, the number of visits a patient makes for breast cancer RT and related services dropped, and remained lower post-COVID-19, due to fewer treatment fractions being prescribed. Average time spent in the department initially decreased but has since increased beyond pre-COVID-19 levels.
Breast cancer is the leading cancer in Ghana, Africa, accounting for 31% of all cancers in women. The effects of breast cancer are not limited to the woman but also impact the spouse’s anxiety, depressed mood, and coping behavior. Helping Her Heal (HHH)-Ghana is a culturally adapted evidenced-based intervention with potential to improve health outcomes of spouse caregivers.
Objectives
The purpose of the study was to ascertain the feasibility, acceptability, and short-term impact of HHH-Ghana, a culturally adapted evidenced-based intervention for spouses of women with breast cancer in Ghana.
Methods
The study used a single group pre–post design. Participants (n = 14) were recruited from medical care providers and were eligible if they were spouse caregivers of wives with Stage I, II, or III breast cancer, were 18 years or older, and had been living with their wives for at least 6 months. Data were obtained by spouse self-report on standardized measures of depressed mood, anxiety, self-care skills, self-efficacy to support their wife, self-efficacy to carry out their own self‐care, and the quality of marital communication about breast cancer. Exit interviews were additionally obtained to describe the gains spouses attributed to their participation in the study.
Results
The HHH-Ghana study was feasible and acceptable. Spouses actively engaged in each intervention session and completed the at-home assignments; retention was 87.5%. Spouses significantly improved on standardized measures of anxiety (p = 0.010), depressed mood (p = 0.002), self-care skills (p = 0.006), and their self-efficacy in supporting their wife (p = 0.001) and in carrying out their own self-care (p = 0.011). Although there was no statistically significant change in marital communication, spouses reported in their exit interviews that the intervention enabled them to communicate better and be more attentive listeners to their wives.
Several breast microwave sensing (BMS) systems have shown encouraging results as a potential breast cancer detection tool. The existing systems in the literature have diverse designs, equipment, measurement protocols, and analysis methods. However, there is relatively little investigation on the impact and performance of varying system designs. This work compares the impact of system design parameters on three existing BMS systems. The first system, a bed-based system, was designed for use in a permanent clinic. The second system, a bench-top system, was created for laboratory research. The third system, a portable system, was designed for use in low-income and remote communities. The bed-based system had the highest resolving capabilities, achieving a spatial resolution of 12.4 ± 0.5 mm. Additionally, the bed system had the highest signal-to-noise ratio of 26 ± 1 dB. The portable system had the least intensity dependence on polar positions within the imaging chamber. The bed system had the highest contrast between tumor- and adipose-mimicking materials. However, the contrast of tumor- and fibroglandular-mimicking materials was similar for each system. By comparing and evaluating the performance of multiple BMS systems, we improve our understanding of system design, allowing for potential studies into an ideal BMS system.
The purpose of this study was to establish a machine-learning model that predicts heart dose in left-sided breast cancer patients treated with volumetric modulated arc therapy (VMAT). As radiotherapy (RT) poses an increased risk of cardiac toxicity, the model employs anatomical features to predict heart dose, tackling a significant issue in the management of breast cancer. This retrospective analysis focused on 53 patients with left-sided breast cancer who received VMAT RT. Various partial arc VMAT techniques were assessed, including the 2P, 4P and 5P methods. Key anatomical parameters measured included mean heart distance (MHD), total heart volume (THV) within the treatment field, heart volume (HV) and planning target volume (PTV). Elastic Net regression models were created to forecast heart dose metrics associated with different VMAT techniques. The Elastic Net regression models successfully predicted heart dose metrics, with VMAT-4P achieving the best performance, reflected in the lowest root mean squared error (RMSE) of 0·9099 and a median absolute error (MEDAE) of 0·5760 for the mean dose. VMAT-5P was particularly effective in predicting V5Gy, with an RMSE of 4·8242 and a MEDAE of 2·1188, while VMAT-2P recorded the lowest MEDAE for V25Gy at 1·0053. The feature importance analysis highlighted MHD as the primary predictor, contributing 75%, followed by THV at 18%, HV at 4% and PTV at 3%. The findings of this study emphasise the critical need to consider patient-specific anatomical features and the effectiveness of VMAT techniques in the treatment planning for left-sided breast cancer. The predictive models established present a pathway for personalised treatment enhancement. Treatment planners are encouraged to assess a range of anatomical characteristics when choosing the optimal VMAT technique.
We consider pricing of a specialised critical illness and life insurance contract for breast cancer (BC) risk. We compare (a) an industry-based Markov model with (b) a recently developed semi-Markov model, which accounts for unobserved BC cases and progression through clinical stages of BC, and (c) an alternative Markov model derived from (b). All models are calibrated using population data in England and data from the medical literature. We show that the semi-Markov model aligns best with empirical evidence. We then consider net premiums of specialized life insurance products under various scenarios of cancer diagnosis and treatment. The results show strong dependence on the time spent with diagnosed or undiagnosed pre-metastatic BC. This proves to be significant for refining cancer survival estimates and accurately estimating related age dependence by cancer stage. In contrast, the industry-based model, by overlooking this critical factor, is more sensitive to the model assumptions, underscoring its limitations in cancer estimates.
Breast cancer patients and survivors deal with physical and psychological challenges due to oncological treatments. The existing literature highlights the importance of compassion in reducing the main cancer-related effects in terms of emotions, quality of life, and dysfunctional coping skills. Over the past few years, compassion-based interventions (CBIs) have been considered an interesting approach to reduce anxiety and depression symptoms and improve quality of life and well-being. However, there have not been many studies that show the benefits of these interventions in breast cancer patients and survivors. The primary objective of this systematic review is to provide evidence of the impact of CBIs on specific variables identified in the literature as affected by this pathology. The variables that will be studied are (a) emotional issues (e.g., anxiety, stress, and depression symptoms); (b) quality of life; and (c) positive coping skills. A systematic search during the previous 10 years up to November 2023 was conducted following the PRISMA guidelines across multiple databases, such as PubMed, Web of Science, PsycINFO, and Scopus. Nine eligible randomized controlled trials were included in this article, with a total of 813 breast cancer patients and survivors. Findings show that CBIs increased compassion, mindful observation, and acting with awareness skills, leading to a significant reduction of anxiety and stress levels, depression, and negative affect. Additionally, less body image distress and greater body appreciation were reported as a consequence of the interventions. This review shows the CBI’s efficacy on emotions, positive coping skills, and quality of life in breast cancer patients and survivors. Guidelines for future studies are listed to promote CBIs as a clinically useful intervention for breast cancer patients and survivors.
While studies have examined the effects of large-scale disasters on disaster-vulnerable individuals, these analyses may not capture the full impact. This study qualitatively explored the impacts of the March 2011 Fukushima triple disaster on patients with breast cancer and their families, aiming to highlight the importance of incorporating family narratives to grasp the full effect of large-scale disasters.
Methods
Utilizing the medical records from two hospitals, deceased patients with breast cancer from the disaster period were identified. Relatives were interviewed using a semi-structured approach. Thematic analysis was conducted via the Braun and Clarke method and Taguette transcription software.
Results
Interviews with seven family members of six patients revealed three main themes: the family’s caregiving burden and their deepened bonds with the patient, the patients’ extensive medical challenges and their physical and mental decline, and the shared confusion during the disaster due to resource shortages and evacuation dilemmas.
Conclusions
This study uncovered significant infrastructural issues such as reduced medical support and the heavy caregiving load on families, amidst some strengthened relationships during a time of crisis. Future research should investigate these issues across various disaster contexts, and proactive measures should be implemented to prevent exacerbation of these challenges.
Breast cancer is a major global health issue, especially among women. Previous research has indicated a possible association between psychiatric conditions, particularly schizophrenia, and an increased risk of breast cancer. However, the specific risk of breast cancer in women with schizophrenia, compared with those with other psychiatric disorders and the general population, remains controversial and needs further clarification.
Aims
To estimate the risk of breast cancer among people with schizophrenia compared with people with other psychiatric disorders and people in the general population.
Method
We utilised medical claims data of women aged 18 to 80 years in the Korean National Health Information Database from 2007 to 2018. Individuals with schizophrenia were defined as women with ICD-10 codes F20 or F25 (n = 224 612). The control groups were defined as women with other psychiatric disorders (n = 224 612) and women in the general Korean population (n = 449 224). Cases and controls were matched by index date and age, in a 1:1:2 ratio. We estimated the hazard of breast cancer using the Cox proportional hazards model, adjusting for insurance premiums and medical comorbidities. Among the people with schizophrenia, we used the landmark method to estimate the association between duration of antipsychotic medication use and the incidence of breast cancer.
Results
In multivariable Cox regression models, the hazard rate of breast cancer was 1.26 times higher in the people with schizophrenia than in the general population (95% CI: 1.20–1.32). In comparison with the psychiatric patient group, the hazard ratio was 1.17 (95% CI: 1.11–1.28). Among women with schizophrenia, the hazard of breast cancer was greater among those who took antipsychotic medications for 1 year or more compared with those who took antipsychotics for less than 6 months.
Conclusions
Women with schizophrenia have an elevated risk of breast cancer, and long-term use of antipsychotics is associated with an increased risk of breast cancer.
This study compares tumor control probability (TCP) and normal tissue complication probability (NTCP) across different hypo-fractionated (HypoRT) and conventional breast radiotherapy regimens using radiobiological models.
Materials and methods:
Computed tomography data from 30 patients with left breast-conserving surgery were used to evaluate three HypoRT regimens (39 Gy and 41·6 Gy in 13 fractions, and 40 Gy in 15 fractions) and a conventional regimen (50 Gy in 25 fractions). Dose-volume histograms (DVHs) were extracted for radiobiological calculations using Equivalent Uniform Dose (EUD) and Poisson models for TCP, and EUD and LKB (Lyman-Kutcher-Burman) models for NTCP.
Results:
Conventional treatment achieved significantly higher TCP (95%) than all HypoRT regimens (p < 0·001), with no significant differences between HypoRT regimens (p > 0·05. The 39 Gy/13 fraction regimen showed the lowest lung NTCP (p < 0·05). HypoRT regimens had significantly lower NTCP for the lungs and heart compared to the conventional regimen (p < 0·01). TCP and NTCP values from Poisson and LKB models were higher than those from the EUD model (p < 0·01).
Conclusion:
HypoRT regimens reduced NTCP, with the lowest values in the regime of 39 Gy/13 fractions regimen, though the conventional regimen had higher TCP.
Mental health challenges are common following cancer diagnosis, negatively impacting treatment and quality of life for breast cancer (BC) patients. This pilot study provides an understanding of the impacts of BC diagnosis and care experiences on the mental health of patients seen at the Aga Khan University Hospital in Nairobi, Kenya. We conducted 40 in-depth interviews, including 10 women with newly diagnosed BC, 10 women with metastatic BC, 10 family members and 10 healthcare professionals. Data were transcribed, translated into English as needed and coded using Dedoose software. Following BC diagnosis, it was reported that patients faced various physical, social, psychological and spiritual factors affecting their mental health and quality of life. Our interviews with each group indicated that BC patients experienced feelings of stress, anxiety and depression related to treatments and accompanying side effects. Disclosure concerns, financial impacts, relationship strain and negative outlooks on life were common among BC patients. The findings indicate that BC diagnosis and care experiences influence mental health in this population. With this basis, understanding and addressing the mental health challenges of BC patients is crucial to improve mental health and quality of life.
Women with breast cancer show dissatisfaction with their appearance, a perception of loss of femininity and bodily integrity, and dissatisfaction with the outcome of the surgery. Body Appreciation (BA) is defined as positive attitudes toward one’s body, beyond satisfaction and dissatisfaction with one’s appearance. Although studies about the protective role of BA have increased, to the best of our knowledge, there are no published studies on the association between BA, body dissatisfaction, and distress in participants with breast cancer. The aims of this study are: (a) To analyze whether BA is a moderator of satisfaction with the body from before breast surgery to the one-year follow-up; and (b) to analyze whether BA is a moderator of distress from before breast surgery to the one-year follow-up. The sample consisted of 115 women diagnosed with breast cancer. Several hierarchical regression analyses were conducted. The results indicated that BA moderated the association between the appearance evaluation before the surgery and the appearance evaluation 12 months after the surgery. Although BA was a significative predictor of distress, it was not a moderator of distress from the moment before breast surgery to the one-year follow-up. This study highlights the importance of evaluating the construct of BA in participants with breast cancer using longitudinal designs and developing psychological interventions that focus on increasing BA.
Breast cancer is the most common cancer in women worldwide, necessitating substantial social support during diagnosis and treatment. This study examines the role of social capital in breast cancer management, focusing on the experiences of patients.
Objectives
The objective of the study was to explore the role of social capital in breast cancer management among women living with breast cancer in Lagos, Nigeria.
Methods
Using a qualitative design, the study recruited 23 women with breast cancer receiving treatment at a teaching hospital in Lagos, Nigeria. Data were content analyzed to identify themes related to social capital.
Results
The study found that social capital, crucial for breast cancer patients’ emotional and instrumental support, stems from various sources such as relatives, immediate family, spouses, places of worship, friends, and neighbors. Effective coping and management of the condition were facilitated through this support network. However, assistance from places of worship, friends, and neighbors was only accessible to those who openly acknowledged their health conditions and had established connections with these social groups. Relationships led to support only when there was a disclosure of the health condition.
Significance of results
(1) This finding reinforces the importance of integrating social support mechanisms including family, friends, and community networks into breast cancer management programs. (2) The study identifies diverse sources of social capital, including relatives, family, spouses, places of worship, friends, and neighbors, stressing the need for tailored support networks. (3) Research reveals the link between health condition disclosure and support accessibility from groups like places of worship and friends, and it emphasizes creating stigma-free environments for patients to disclose health status comfortably. (4) The study highlights family involvement in breast cancer management as crucial for effective coping. Healthcare professionals should prioritize interventions strengthening family support systems. (5) Findings of stress community support for better breast cancer outcomes, advocating for initiatives like support groups and awareness campaigns to boost social capital and aid affected individuals.
Conclusion
The study emphasizes the significance of involving family members in the breast cancer management process and highlights the need for support systems within families and communities to facilitate better outcomes for breast cancer patients.
The aim of this study was to develop a method for accurately measuring the intra-fraction motion in cine electronic portal imaging device (EPID) images of tangential breast irradiation.
Patients and methods:
The cine EPID images were acquired for 18 breast cancer patients during medial tangential breast radiotherapy. The skin surface and the chest wall were segmented separately in each EPID image using an automated MATLAB algorithm to obtain the magnitude of intra-fraction motion.
Results:
The patients had an average age of 55 years (range 43–69 years), with the highest observed displacement at 3·50 mm. The mean intra-fraction motion due to respiration for the skin surface and chest wall was 1·04 ± 0·24 mm and 1·10 ± 0·27 mm, respectively. The amount of intra-fraction motion showed no significant association with either the patient’s age or the side of the breast receiving the treatment.
Conclusion:
In this study, by utilising cine EPID technology and the automated MATLAB algorithm, the intra-fraction motion during breast radiotherapy treatment was accurately measured and analysed. Results indicate minimal skin surface and chest wall motion (approximately 1 mm), confirming negligible intra-fraction motions during conformal radiotherapy in breast cancer patients.
Depression is a common co-morbidity in women with breast cancer. Previous systematic reviews investigating cognitive behavioural therapy (CBT) for depression in this population based their conclusions on findings from studies with varying and often limited specificity, quality and/or quantity of CBT within their interventions.
Aim:
To determine the effectiveness of a specific, well-evidenced CBT protocol for depression in women with breast cancer.
Method:
Online databases were systematically searched to identify randomised controlled trials (RCTs) testing CBT (aligned to Beck’s protocol) as a treatment for depression in women with breast cancer. Screening, data extraction and risk of bias assessment were independently undertaken by two study authors. Both narrative synthesis and meta-analysis were used to analyse the data. The meta-analysis used a random effects model to compare CBT with non-active/active controls of depression using validated, self-report measures.
Results:
Six RCTs were included in the narrative synthesis, and five in the meta-analysis (n = 531 participants). Overall, CBT demonstrated an improvement in depression scores in the CBT condition versus active and non-active controls at post-intervention (SMD = –0.93 [95% CI –1.47, –0.40]). Narratively, five out of six RCTs reported statistically significant improvements in depression symptoms for CBT over control conditions for women with breast cancer.
Conclusion:
CBT aligned to Beck’s protocol for depression appears effective for treating depression in women with breast cancer. However, further research is needed for women with stage IV breast cancer. The clinical recommendation is that therapists utilise Beck’s CBT protocol for depression, whilst considering the complex presentation and adapt their practice accordingly.
The current study assessed the views and attitudes of health professionals (HPs) regarding factors associated with energy balance-related health behaviours and weight management in breast cancer survivors (BCS) with overweight and obesity. Semi-structured online interviews were conducted with 21 HPs (oncologists, dietitians- nutritionists, physical education instructors, mental health professionals, and nurses) from Attica and Thessaly. Thematic analysis was used to analyse and present the data. Four main themes arose from the data: “The patients’ mental health wellbeing”, “Survivors’ interest in diet and exercise”, “Interdisciplinary collaboration in patient’s care”, and “Maintaining normality”. HPs agreed that weight loss in BCS with overweight and obesity is important, but negative mental health wellbeing is a main barrier to behaviour change. For many BCS their cancer diagnosis is a “teachable” moment for weight management, especially for women of younger age, who are more keen to discuss weight management issues. Essential characteristics that determine/facilitate behavioural change include education, commitment for regular communication, personalised intervention, and interdisciplinary collaboration. According to HPs, future weight loss interventions should take into account BCS’s mental health wellbeing and level of motivation and should provide regular support and education.
Cognitive changes following adjuvant treatment for breast cancer (BC) are well documented particularly following chemotherapy. However, limited studies have examined cognitive and/or language functions in chemotherapy-naive women with BC taking tamoxifen (TAM). While there is some compelling evidence TAM affects cognitive and language domains, language has not been studied beyond semantics (i.e., content of language), which is just one aspect of language. Using ambulatory cognitive assessment, we investigated the trajectory of cognitive and language changes during early period of adjuvant endocrine treatment (tamoxifen) in women with BC at two time periods (pre-treatment and two months after treatment begins).
Participants and Methods:
Four women with BC (mean age = 62.25 years, SD = 8.38) and 18 cognitively healthy age-matched controls (mean age = 59.77, SD = 7.45) completed 3 cognitive tasks using smartphones, during a short time period (5 days) and repeated at two time periods. Symbol search, dot memory and color dots tasks were used to measure the cognitive constructs - processing speed and working memory. Response times were recorded in milliseconds. To determine language ability, language samples were collected at two time periods, where the participants described two stories from two wordless picture books and samples were assessed using core lexicon analyses.
Results:
Wilcoxon-signed rank test was computed to identify cognitive and linguistic changes during early period of TAM administration in women with BC at two time periods. No significant within group or between group differences were seen on the cognitive and language tasks at the two time periods, however, a trend for decline in performance was seen in some BC participants across different tasks.
Conclusions:
This is the first study to our knowledge to use ambulatory cognitive assessment method and study discourse-level language function during this early period (pre-treatment and 2 months post-TAM). Findings from the current study advance our understanding of trajectories of cognition and language changes during the initial course of adjuvant endocrine treatment for women with BC with ER+ tumors. Using a measurement-burst design and ambulatory cognitive assessment, we were able to apply better precision measurement to identify distinct cognitive constructs affected by adjuvant endocrine treatment. In addition, insight into changes in discourse ability are impactful for numerous reasons: (1) better understanding of how adjuvant endocrine therapy impacts communication and (2) discernment into language domains that may require early behavioral intervention.
