Health-related quality of life in Black breast cancer survivors with and without triple-negative breast cancer (TNBC)

Patient-reported symptoms before adjuvant locoregional radiotherapy for breast cancer: triple-negative histology impacts the symptom burden

BACKGROUND

Multimodal breast cancer treatment may cause side effects reflected in patient-reported outcomes and/or symptom scores at the time of treatment planning for adjuvant radiotherapy. In our department, all patients have been assessed with the Edmonton Symptom Assessment System (ESAS; a questionnaire addressing 11 major symptoms and wellbeing on a numeric scale of 0-10) at the time of treatment planning since 2016. In this study, we analyzed ESAS symptom severity before locoregional radiotherapy.

PATIENTS AND METHODS

Retrospective review of 132 patients treated between 2016 and 2021 (all comers in breast-conserving or post-mastectomy settings, different radiotherapy fractionations) was performed. All ESAS items and the ESAS point sum were analyzed to identify subgroups with higher symptom burden and thus need for additional care measures.

RESULTS

The biggest patient-reported issues were fatigue, pain, and sleep problems. Patients with triple negative breast cancer reported a higher symptom burden (mean 30 versus 20, p = 0.038). Patients assigned to adjuvant endocrine therapy had the lowest point sum (mean 18), followed by those on Her-2-targeting agents without chemotherapy (mean 19), those on chemotherapy with or without other drugs (mean 26), and those without systemic therapy (mean 41), p = 0.007. Those with pathologic complete response after neoadjuvant treatment had significantly lower anxiety scores (mean 0.7 versus 1.8, p = 0.03) and a trend towards lower depression scores, p = 0.09.

CONCLUSION

Different surgical strategies, age, and body mass index did not impact on ESAS scores, while the type of adjuvant systemic therapy did. The effect of previous neoadjuvant treatment and unfavorable tumor biology (triple negative) emerged as important factors associated with symptom burden, albeit in different domains. ESAS data may facilitate identification of patients who should be considered for additional supportive measures to alleviate specific symptoms.

Modulatory Effects of XIAOPI Formula on CXCL1 and Selected Outcomes in Triple-Negative Breast Cancer: A Randomized Controlled Clinical Trial

Background

Triple-negative breast cancer (TNBC) is the most aggressive malignancy. Psychological distress and elevated CXCL1 level have been reported to be closely associated with the poor prognosis and quality of life of patients with TNBC. In preclinical studies using xenograft mouse models, XIAOPI formula, a nationally approved drug prescribed to patients at high risk for breast cancer, inhibited CXCL1 expression and improved survival. Traditional Chinese medicine has unique advantages in improving patients' emotional disorders and quality of life. However, the impact of XIAOPI formula on the serum level of CXCL1, psychological distress, and quality of life among patients with TNBC is currently unknown.

Methods

In this study, we designed a randomized, double-blind, placebo-controlled trial. Patients with TNBC were randomly assigned to receive either the XIAOPI formula or a placebo for three months. The primary outcomes include serum CXCL1 expression, Self-Rating Anxiety Scale (SAS), and the Self-Rating Depression Scale (SDS). Secondary outcomes included the Pittsburgh Sleep Quality Index (PSQI) and the Functional Assessment of Cancer Therapy-Breast (FACT-B).

Results

A total of 60 patients with TNBC were enrolled in the investigation. The results showed that the XIAOPI formula significantly decreased CXCL1 expression compared with the control group. Moreover, in comparison to the placebo, the XIAOPI formula increased FACT-B scores while decreasing SDS, SAS, and PSQI scores.

Conclusion

In patients with TNBC, XIAOPI formula may be effective in reducing CXCL1 levels, enhancing psychological well-being, and quality of life. While our research offers a natural alternative therapy that may enhance the prognosis of TNBC, future validation of its therapeutic effects will require large-scale, long-term clinical trials.

Advanced Triple-Negative Breast Cancer

OBJECTIVES

Our focus within this review is to summarize key advances and new therapeutic approaches within advanced triple-negative breast cancer. In addition, we highlight the importance of multidisciplinary management, discussing key issues for patients and importance of the supportive role that specialist nurses provide.

DATA SOURCES

Peer-reviewed literature, clinical practice guidelines, clinical trial, and government websites.

CONCLUSION

Triple-negative breast cancer is a highly heterogeneous subtype of breast cancer, often associated with a less favorable prognosis compared to other types. Significant advances in our understanding of specific mutations and signaling pathways within this subtype, coupled with expanding therapeutic options, has broadened the treatment landscape considerably. While chemotherapy traditionally formed the mainstay of treatment, new therapeutics such as immunotherapy, targeted agents, and antibody-drug conjugates in first-line and subsequent-line settings are now available. It is essential for all those who care for this patient group to be up-to-date on current practice and emerging treatments, so patients receive the support they need and deserve.

IMPLICATIONS FOR NURSING PRACTICE

Nurses need to become familiar with new systemic anticancer therapies within advanced triple-negative breast cancer to provide patients with adequate information about new treatment options and support with potential treatment-associated toxicities. It is important for nurses to be able to recognise key issues facing patients with a diagnosis of advanced triple-negative breast cancer, to gain a deeper understanding of both the physical and psychosocial support required, signposting or referring patients to additional support services if needed.

Anxiety and depression among Black breast cancer survivors: Examining the role of patient-provider communication and cultural values

OBJECTIVE

Breast cancer survivors frequently experience anxiety and depression post-treatment. Patient-provider communication and cultural values may impact these psychological outcomes. We examined the impact of patient-provider communication and cultural values on anxiety and depression among Black breast cancer survivors.

METHODS

Using an observational, cross-sectional design, 351 survivors self-reported patient-provider communication (quality, confidence), cultural values (religiosity, collectivism, future time orientation), anxiety, and depression. Patients were categorized into high, moderate, and low levels of communication and cultural values. Separate linear regressions examined the effect of levels of communication and cultural values on anxiety and depression, controlling for sociodemographic variables.

RESULTS

A subset of breast cancer survivors reported clinically significant symptoms of anxiety (40%) and depression (20%). Communication was associated with anxiety (β = -0.14, p = 0.01) and depression (β = -0.10, p = 0.04). Specifically, women reporting higher levels of communication quality/confidence reported lower levels of anxiety and depression. There was a trend towards a significant association between cultural values and depression (β = -0.09, p = 0.06).

CONCLUSIONS

Black breast cancer survivors experience poor psychological functioning. Effective patient-provider communication may reduce anxiety and depression post-treatment.

PRACTICE IMPLICATIONS

Patient-provider relationships and patient empowerment may be key components of cancer survivorship. Special attention should be paid to patient-centered communication for Black breast cancer survivors.

Economic and Humanistic Burden of Triple-Negative Breast Cancer: A Systematic Literature Review

BACKGROUND

Triple-negative breast cancer (TNBC) accounts for 10-20% of all breast cancers (BCs). It is more commonly diagnosed in younger women and often has a less favorable prognosis compared with other BC subtypes.

OBJECTIVE

The objective of this study was to provide a literature-based extensive overview of the economic and humanistic burden of TNBC to assist medical decisions for healthcare payers, providers, and patients.

METHODS

A systematic literature review was performed using multiple databases, including EMBASE, MEDLINE, Econlit, the Cochrane Central Register of Controlled Trials, and the Cochrane Database of Systematic Reviews, from database inception to 16 May 2021. In addition, a targeted search was performed in the Northern Light Life Sciences Conference Abstracts database from 2016 through June 2021. The bibliographies of included articles were reviewed to identify other potentially relevant publications. Quality assessment of the included studies was conducted.

RESULTS

The review identified 19 studies assessing the economic burden and 10 studies assessing the humanistic burden of TNBC. Studies varied widely in study design, settings, patient populations, and time horizons. The estimates of mean per-patient annual direct medical costs ranged from around $20,000 to over $100,000 in stage I-III TNBC and from $100,000 to $300,000 in stage IV TNBC. Healthcare costs and resource utilization increased significantly with disease recurrence, progression, and increased cancer stage or line of therapy. Compared with the costs of systemic anticancer therapy, cancer management costs comprised a larger portion of total direct costs. The estimates of indirect costs due to productivity loss ranged from $207 to $1573 per patient per month (all costs presented above were adjusted to 2021 US dollars). Cancer recurrence led to significantly reduced productivity and greater rates of leaving the workforce. A rapid deterioration of health utility associated with disease progression was observed in TNBC patients. Treatment with pembrolizumab or talazoparib showed significantly greater improvements in health-related quality of life (HRQoL) compared with chemotherapy, as measured by EORTC QLQ-C30, QLQ-BR23, and FACT-B.

CONCLUSION

TNBC is associated with a substantial economic burden on healthcare systems and societies and considerably reduced productivity and HRQoL for patients. This study synthesized the published literature on the economic and humanistic burden of TNBC and highlighted the need for continued research due to the rapidly changing landscape of TNBC care.

Association between aspects of social support and health-related quality of life domains among African American and White breast cancer survivors

PURPOSE

Social support is associated with breast cancer survivors' health-related quality of life (HRQoL). More nuanced information is needed regarding aspects of social support associated with different HRQoL domains among diverse populations. We assessed the association between emotional/informational and tangible support and five HRQoL domains and evaluated race as an effect modifier.

METHODS

African American and White women (n = 545) diagnosed with hormone-receptor-positive breast cancer completed a survey that assessed sociodemographic, clinical, and psychosocial factors. We assessed bivariate relationships between emotional/informational and tangible support along with overall HRQoL and each HRQoL domain.We tested interactions between race and emotional/informational and tangible social support using linear regression.

RESULTS

The sample included African American (29%) and White (71%) breast cancer survivors. Emotional/informational social support had a statistically significant positive association with emotional well-being (β = .08, p = 0.005), social well-being (β = 0.36, p < 0.001), functional well-being (β = .22, p < .001), breast cancer concerns (β = .16, p = 0.002), and overall HRQoL (β = .83, p < .001). Similarly, tangible social support had a statistically significant positive association with emotional well-being (β = .14, p = 0.004), social well-being (β = .51, p < .001), functional well-being (β = .39, p < .001), and overall HRQoL (β = 1.27, p < .001). The interactions between race and social support were not statistically significant (p > 0.05).

CONCLUSIONS

Results underscore the importance of the different social support types among breast cancer survivors, regardless of survivors' race.

IMPLICATIONS FOR CANCER SURVIVORS

Population-based interventions can be standardized and disseminated to provide guidance on how to increase emotional/information and tangible support for all breast cancer survivors by caregivers, health providers, and communities.

Health-Related Quality of Life Among Patients With HR+/HER2- Early Breast Cancer

PURPOSE

The goal of this study was to characterize health-related quality of life (HRQOL) among patients diagnosed with early-stage, hormone receptor-positive (HR+)/human epidermal growth factor receptor 2 negative (HER2-) breast cancer.

METHODS

A multinational (United States, Japan, France, Germany, Italy, Spain, and United Kingdom) study of patients diagnosed with stage I to III HR+/HER2- breast cancer, either receiving adjuvant treatment or under postadjuvant surveillance, was conducted between June and October 2019. Patients were identified by their consulting physician and invited to complete the Functional Assessment of Cancer Therapy-Breast (FACT-B) and the EQ-5D-5L pen and paper questionnaires. EQ-5D-5L index scores were derived by using available country-specific health state value sets, where available, and numerically compared with general population scores derived from published normative and population data. Descriptive summary statistics were reported for FACT-B, Functional Assessment of Cancer Therapy-General (FACT-G) (total and specific subscales), the EQ-5D index scores, and the EQ-VAS scores for each country. Results were stratified according to disease-free treatment status (active adjuvant treatment or postadjuvant surveillance), age (25-44, 45-54, 55-64, or ≥65 years), stage (I, II, or III), and menopausal status at the time of questionnaire completion (pre-/peri-menopausal or postmenopausal).

FINDINGS

Overall, 1110 patients completed the HRQOL questionnaires (mean age, 59 years; 79% active adjuvant treatment, and 21% under surveillance postadjuvant treatment at time of questionnaire administration; 31% stage I, 48% stage II, and 20% stage III at diagnosis). Of these, 1102 completed the FACT-B and 1083 completed the EQ-5D-5L questionnaires. The mean (SD) FACT-B total score was 99.0 (21.9). The mean FACT-G total score was 72.5 (17.8), which was comparable to the published normative score. The mean EQ-5D index and EQ-VAS scores for each country were similar to corresponding population means; EQ-5D index scores ranged from 0.842 (0.098) in Japan to 0.916 (0.109) in France, and EQ-VAS scores from 68.0 (18.4) in Germany to 78.6 (16.4) in the United States. In addition, mean scores were comparable between the active adjuvant treatment and postadjuvant surveillance groups for the FACT-B total (99.4 [22.5] and 97.7 [19.7], respectively), FACT-G total (72.8 [18.3] and 71.3 [16.0]), EQ-5D index score (0.868 [0.135] and 0.869 [0.142]), and EQ-VAS (74.9 [17.2] and 74.4 [16.1]).

IMPLICATIONS

Patient-reported HRQOL among patients with HR+/HER2- early breast cancer who were disease-free was high, with reported scores comparable to normative scores. These results improve our understanding of HRQOL among patients with early disease and may facilitate future studies examining the potential impact of adjuvant treatment and disease recurrence, including metastasis.

Chemotherapy-Induced Peripheral Neurotoxicity as A Risk Factor for Poor Sleep Quality in Breast Cancer Survivors Treated with Docetaxel

Objective:

The purpose of this study was to explore sleep quality and to determine whether chemotherapy-induced peripheral neurotoxicity is a risk factor for poor sleep quality in breast cancer survivors who receive docetaxel treatment.

Methods:

Secondary data analysis from a cross-sectional study. Sample characteristics were collected using an information sheet. Independent variables included the Hospital Anxiety and Depression Scale (HADS), the Patient Neurotoxicity Questionnaire (PNQ), and the Identification Pain Questionnaire (ID pain). Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). We performed descriptive analyses and simple logistic regression.

Results:

A total of 98 participants were included. More than 60% of them reported poor sleep quality, with their average PSQI score being 7.54 ± 4.45. Poor subjective sleep quality (1.37 ± 0.88) and short sleep duration (1.37 ± 1.08) were their main problems. In addition, significant risk factors for poor sleep quality were chronic illness (odds ratio [OR] = 2.753, P = 0.041), anxiety (OR = 7.714, P = 0.009), neuropathic pain (OR = 11.261, P = 0.022), sensory neuropathy (OR = 2.529, P = 0.032), motor neuropathy (OR = 3.781, P = 0.002), and undergoing chemotherapy (OR = 2.593, P = 0.027). Targeted therapy that some survivors received served as a protective factor (OR = 0.351, P = 0.015).

Conclusions:

We found a high prevalence of poor sleep quality in breast cancer survivors treated with docetaxel. The results indicated that, in addition to clinical characteristics and psychological discomfort, chemotherapy-induced peripheral neurotoxicity is a significant risk factor for poor sleep quality.

Pre-diagnostic allostatic load and health-related quality of life in a cohort of Black breast cancer survivors

PURPOSE

To determine the association of pre-diagnostic allostatic load (AL) with health-related quality of life (HRQOL) among Black women with breast cancer.

METHODS

In a sample of 409 Black women with non-metastatic breast cancer enrolled in the Women's Circle of Health Follow-Up Study (WCHFS), two pre-diagnostic AL measures were estimated using medical records data from up to 12 months prior to breast cancer diagnosis: AL-lipid/metabolic profile-based measure and AL-inflammatory profile-based measure. HRQOL was assessed approximately 24 months post diagnosis, using the Functional Assessment of Cancer Therapy-Breast Cancer (FACT-B) instrument, including 5 subscale scores [presented by physical well-being (PWB), social & family well-being (SFWB), emotional well-being (EWB), functional well-being (FWB), and breast cancer-specific scale (BCS)] and 3 derived total scores [presented by trial outcome index (TOI), Functional Assessment of Cancer Therapy-General (FACT-G) and FACT-B]. We used multivariable logistic regression models, using dichotomized AL scores (lower AL: 0-3 points, higher AL: 4-8 points), to assess the associations between the two pre-diagnostic AL measures and HRQOL.

RESULTS

Higher pre-diagnostic AL was associated with poorer FWB and lower FACT-G, but these associations were statistically significant for the AL-inflammatory profile-based measure (FWB: OR 1.63, 95% CI 1.04, 2.56; FACT-G: OR 1.62, 95% CI 1.04, 2.54), but not the AL-lipid/metabolic profile-based measure (FWB: OR 1.45, 95% CI 0.81, 2.59; FACT-G: OR 1.33, 95% CI 0.75, 2.37).

CONCLUSION

These findings suggest that higher AL, particularly when measured using the inflammatory profile-based measure, was associated with poorer HRQOL, namely FWB and FACT-G, among Black breast cancer survivors.

Quality of life among breast cancer survivors with triple negative breast cancer--role of hope, self-efficacy and social support

PURPOSE

To investigate quality of life status and its influence factors among Chinese triple negative breast cancer patients, especially the role of hope, self-efficacy and social support.

METHOD

121 triple negative breast cancer patients were recruited from March to June 2019. Data was collected by demographic and clinical characteristics questionnaire and instruments assessing hope, social support, self-efficacy and quality of life. Descriptive statistics, independent samples t-tests or one-way analysis of variance, Pearson correlation analyses and multiple regression analyses were applied.

RESULTS

Hope, social support and self-efficacy were all positively correlated with quality of life (P < 0.001). Multiple regression analyses indicated hope, income, cancer stage, self-efficacy, and social support as indicators of quality of life, explaining 56.2% of the response variation (P < 0.001).

CONCLUSIONS

Quality of life of triple negative breast cancer patients need to be improved. Income, hope, self-efficacy and social support are positive predictors, and cancer stage are negative predictors of quality of life. Supportive programs and interventions targeting on increasing levels of hope, self efficacy and social support should be considered while caring for this group.

Identification of Distinct Heterogenic Subtypes and Molecular Signatures Associated with African Ancestry in Triple Negative Breast Cancer Using Quantified Genetic Ancestry Models in Admixed Race Populations

Triple negative breast cancers (TNBCs) are molecularly heterogeneous, and the link between their aggressiveness with African ancestry is not established. We investigated primary TNBCs for gene expression among self-reported race (SRR) groups of African American (AA, n = 42) and European American (EA, n = 33) women. RNA sequencing data were analyzed to measure changes in genome-wide expression, and we utilized logistic regressions to identify ancestry-associated gene expression signatures. Using SNVs identified from our RNA sequencing data, global ancestry was estimated. We identified 156 African ancestry-associated genes and found that, compared to SRR, quantitative genetic analysis was a more robust method to identify racial/ethnic-specific genes that were differentially expressed. A subset of African ancestry-specific genes that were upregulated in TNBCs of our AA patients were validated in TCGA data. In AA patients, there was a higher incidence of basal-like two tumors and altered TP53, NFB1, and AKT pathways. The distinct distribution of TNBC subtypes and altered oncologic pathways show that the ethnic variations in TNBCs are driven by shared genetic ancestry. Thus, to appreciate the molecular diversity of TNBCs, tumors from patients of various ancestral origins should be evaluated.

Perceptions of a Breast Cancer Survivorship Intervention: Pearls of Wisdom from Young African American Women

PURPOSE

African American (AA) women ages 20-44 develop breast cancer at higher rates compared with Caucasian women. These young survivors (<45 years) also have disparate quality of life (QOL). Little is known about survivorship information needs of young AA survivors. The purpose of this study was to explore young AA survivors' perceptions of an existing QOL intervention for breast cancer survivors, identifying information needs to address using a targeted intervention.

METHODS

Two semistructured interviews were conducted with each of 15 young AA survivors who had completed breast cancer treatment. This article focuses on the second interview in which young AA survivors reviewed intervention materials and described their perceptions of the intervention. Content analysis was used to identify themes, which were validated by participants.

RESULTS

Participants (n: 15; mean age at study entry: 35 years) reported that the existing evidence-based intervention discussed relevant but general survivorship information. They suggested adapting the information for young AA survivors: addition of content geared toward finances, how to better communicate to manage dating and relationships, how to engage in healthful activities, and how to find local resources for any stage of survivorship. Furthermore, they suggested multiple modes of information delivery and inclusion of diverse imagery.

CONCLUSION

Engaging young AA survivors yielded pearls of wisdom, highlighting the general nature of an existing intervention and suggesting adaptations to meet young AA survivors' information needs. Applying such pearls can be a powerful method to target survivorship interventions for this disparate group of cancer survivors.
