Patterns, correlates, and prognostic significance of quality of life following breast cancer

Association between quality of life and mortality risk in patients with breast cancer: a systematic review and meta-analysis

BACKGROUND

Patients with breast cancer present with various problems that have an adverse effect on the quality of life (QOL). However, the association between the QOL and mortality among patients with breast cancer remains controversial. Therefore, this systematic review and meta-analysis aimed to determine whether QOL impacts prognosis in patients with breast cancer.

METHODS

The databases of CINAHL, Scopus, and PubMed databases were searched to retrieve observational studies that assessed the QOL and mortality risk in patients with breast cancer published before December 2022.

RESULTS

Among the 119,061 articles retrieved, six observational studies were included in the meta-analysis. Physical QOL (hazard ratio [HR]: 1.04, 95% confidence interval [CI]: 1.01-1.07, p = 0.003), emotional QOL (HR: 1.01, 95% CI: 1.00-1.03, p = 0.05), and role QOL (HR: 1.01, 95% CI: 1.00-1.01, p = 0.007) showed significant associations with mortality risk. In contrast, global QOL, cognitive QOL, and social QOL showed no associations with mortality risk. Subgroup analysis performed according to treatment time points revealed that the post-treatment physical QOL was associated with mortality risk.

CONCLUSIONS

Physical QOL, emotional QOL, and role QOL are associated with mortality risk in patients with breast cancer. Furthermore, post-treatment physical QOL showed a more significant association with prolonged survival than pre-treatment physical QOL.

Global quality of life and mortality risk in patients with cancer: a systematic review and meta-analysis

PURPOSE

This systematic review and meta-analysis aimed to examine the impact of global quality of life (QOL) on mortality risk in patients with cancer, considering cancer type and timepoint of QOL assessment.

METHODS

A systematic search was conducted using Cumulated Index to Nursing and Allied Health Literature, PubMed/MEDLINE, and Scopus databases from inception to December 2022. Observational studies that assessed QOL and examined mortality risk in patients with cancer were extracted. Subgroup analyses were performed for cancer types and timepoints of QOL assessment.

RESULTS

Overall, global QOL was significantly associated with mortality risk (hazard ratio: 1.06, 95% confidence interval: 1.05-1.07; p < 0.00001). A subgroup analysis based on cancer type demonstrated that lung, head and neck, breast, esophagus, colon, prostate, hematologic, liver, gynecologic, stomach, brain, bladder, bone and soft tissue, and mixed type cancers were significantly associated with mortality risk; however, melanoma and pancreatic cancer were not significantly associated with mortality risk. Additionally, global QOL was associated with mortality risk at all timepoints (pretreatment, posttreatment, and palliative phase); pretreatment QOL had the largest impact, followed by posttreatment QOL.

CONCLUSION

These findings provide evidence that QOL is associated with mortality risk in patients with cancer at any timepoint. These results indicate the importance of evaluating the QOL and supportive interventions to improve QOL in any phase.

Immigration Transition and Symptom Distress Changes by a Technology-Based Intervention: Asian American Breast Cancer Survivors

Technology-based programs using computers and mobile devices are known to be effective in providing information and support to marginalized populations including immigrants. Yet, little is still known on the factors that may influence the effectiveness of technology-based programs in improving symptom experience, including immigration transition, especially among Asian American breast cancer survivors. This study aimed to identify the characteristics related to immigration transition that significantly affected the symptom distress changes by a technology-based information and coaching/support program among Asian American breast cancer survivors. This secondary analysis was conducted with the data from 102 Asian American breast cancer survivors from a randomized clinical trial in progress. Multiple instruments were used: the questions on background characteristics and immigration transition and the Memorial Symptom Assessment Scale-Short Form. The data were analyzed using repeated-measurement analyses and decision tree analyses. The mean changes in the symptoms distress scores were as follows: -0.12 (SD, 0.47) in the Global Distress Index scores; -0.08 (SD, 0.43) in the physical symptom distress scores; and -0.15 (SD, 0.65) in the psychological symptom distress scores. The characteristics with the highest impact on the symptom distress score changes included the immigration age for Global Distress Index and physical symptom distress score and the level of acculturation for psychological symptom distress score.

Cancer Patients’ Age-Related Benefits from Mobile Neurofeedback-Therapy in Quality of Life and Self-efficacy: A Clinical Waitlist Control Study

Electroencephalographic neurofeedback (EEG NF) can improve quality of life (QoL) and reduce distress by modifying the amplitude of selected brain frequencies. This study aims to investigate the effects of NF therapy on QoL and self-efficacy in cancer patients and to explore age-related reactions. In a waitlist control paradigm, psychometric data (EORTC QLQ-C30, General Self-Efficacy Scale) of 20 patients were collected at three different time points, each five weeks apart. An outpatient 10-session NF intervention (mobile) was conducted between the second and third measurement point. QoL and self-efficacy changed significantly over time (QoL: F(2,36) = 5.294, p < .05, η2 = .227; Self-efficacy: F(2,26) = 8.178, p < .05, η2 = .386). While QoL increased in younger patients, older patients initially showed a decrease in QoL, which then increased during intervention. Younger patients did not differ from older patients in QoL in both waitlist control (T0-T1) and intervention phase (T1–T2). QoL in older patients significantly differed between waitlist control and intervention phase (Z = − 2.023, p < .05, d = 1.085). Self-efficacy increased in both age categories. Younger and older patients did not differ in self-efficacy in waitlist control, but in intervention phase (F(1,16) = 7.014, p < .05, η2 = .319). The current findings suggest that NF therapy is a promising treatment modality for improving QoL in cancer patients. Our study reveals NF being a tool to influence self-efficacy, which should receive more appreciation in clinical care. However, the effect of NF in different age groups as well as the influence on further cancer-related symptoms should be investigated in future research.

Physical activity trajectories following gynecological cancer: results from a prospective, longitudinal cohort study

BACKGROUND

Participating in physical activity after a diagnosis of cancer is associated with reduced morbidity and improved outcomes. However, declines in, and low levels of, physical activity are well documented in the broader cancer population, but with limited evidence following gynecological cancer.

OBJECTIVE

To describe physical activity levels from before and up to 2 years after gynecological cancer surgery; to explore the relationship between physical activity patterns and quality of life; and to describe characteristics associated with physical activity trajectories post-gynecological cancer.

METHODS

Women with gynecological cancer (n=408) participated in a prospective study that assessed physical activity and quality of life pre-surgery (baseline), at 6 weeks, and 3, 6, 9, 12, 15, 18 and 24 months post-surgery. Validated questionnaires were used to assess physical activity (Active Australia Survey) and quality of life outcomes (Functional Assessment of Cancer Therapy-General). Generalized estimating equation modeling, group-based trajectory analysis, and analysis of variance were used to identify physical activity levels over time, to categorize women into physical activity trajectory groups, and to assess the relationship between physical activity levels and quality of life, respectively.

RESULTS

Women had a mean±SD age of 60±11.4 years at diagnosis, with the majority diagnosed with endometrial cancer (n=235, 58%) or stage I disease (n=241, 59%). Most women (80%) started with and maintained low levels of physical activity (1-10 metabolic equivalent task hours per week), reported no physical activity throughout the follow-up period, or reduced physical activity levels over time. Only 19% of women maintained or doubled physical activity levels, so that by 24 months post-diagnosis they were engaging in sufficient levels of physical activity. Women with endometrial cancer (58% of the sample) were more likely to be overweight or obese and to report low levels of physical activity or none at all. Higher physical activity levels were associated with higher quality of life (p<0.05).

CONCLUSION

The low baseline and surveillance levels of physical activity show that the vast majority of gynecological cancer survivors have the ability to improve their physical activity levels. Integration of physical activity advice and support into standard care could lead to gains in quality of life during gynecological cancer survivorship.

Study protocol for a multisite randomised controlled trial of a rehabilitation intervention to reduce participation restrictions among female breast cancer survivors

INTRODUCTION

Many breast cancer survivors report an inability to fully participate in activities of daily living after completing cancer treatment. Reduced activity participation is linked to negative consequences for individuals (eg, depression, reduced quality of life) and society (reduced workforce participation). There is currently a lack of evidence-based interventions that directly foster cancer survivors' optimal participation in life roles and activities. Pilot study data suggest rehabilitation interventions based on behavioural activation (BA) and problem-solving treatment (PST) can facilitate post-treatment role resumption among breast cancer survivors.

METHODS AND ANALYSIS

This protocol describes a multisite randomised controlled trial comparing a 4-month long, nine-session BA and PST-informed rehabilitation intervention (BA/PS) against a time-matched, attention control condition. The overall objective is to assess the efficacy of BA/PS for enhancing breast cancer survivors' activity participation and quality of life over time. A total of 300 breast cancer survivors reporting participation restrictions after completing curative treatment for stage 1-3 breast cancer within the past year will be recruited across two sites (Dartmouth-Hitchcock Medical Center and University of Alabama at Birmingham). Assessments are collected on enrolment (T1) and 8 (T2), 20 (T3) and 44 (T4) weeks later.

ETHICS AND DISSEMINATION

Study procedures are approved by the Committee for the Protection of Human Subjects at Dartmouth College, acting as the single Institutional Review Board of record for both study sites (STUDY 00031380). Results of the study will be presented at national meetings and submitted for publication in peer-reviewed journals.

Determining Occupational Performance Issues in Women with Breast Cancer Referred to Treatment Centers of Hamadan, Iran

Objective: Women with breast cancer experience functional limitations at the time of diagnosis and after the initial treatment of cancer. Such limitations interfere with participation in self-care, work affairs, and leisure activities. The present study aimed to determine occupational performance priorities in women with breast cancer who had referred to treatment centers in Hamadan, Iran. Methods: In this cross-sectional, descriptive-analytical study, 102 women with breast cancer who had referred to treatment centers in Hamadan were selected through convenience sampling. The participants’ information was gathered using their medical records and a demographic information questionnaire. Then, they were interviewed using the Canadian Occupational Performance Measure (COPM) to determine their occupational performance issues. The gathered data were coded and analyzed using the SPSS statistical software, version 16. Results: The results indicated that out of the 22 defined codes for the patients’ selected activities, 45.8%, 30.8%, and 23.4% belonged to self-care, productivity, and leisure domains, respectively. Conclusion: Women with breast cancer experience various occupational performance issues due to disease complications and received treatments. In the present study, self-care comprised the occupational performance priority. Determining the clients’ intervention priorities, which is among the bases of occupational therapy interventions, can help women with breast cancer reach the desired quality of life.

When do patient reported quality of life indicators become prognostic in breast cancer?

Background

Various patient reported quality-of-life indicators are independently prognostic for survival in metastatic breast cancer and other cancers. The same measures recorded at first diagnosis of early breast cancer carry no corresponding prognostic information. The present study aims to assess at what time in the disease evolution the prognostic association appears.

Methods

Among 8024 patients enrolled in one of seven randomized controlled trials in early-stage breast cancer 3247 had a breast cancer relapse after a median follow-up of 12.1 years. Of these 677 had completed QL indicator assessments within defined windows 1, 2 or 3 months prior to relapse. We performed Cox regression analyses using these assessments and using identical instruments after relapse. All analyses were stratified by trial and adjusted for baseline clinicopathologic factors.

Results

QL indicators in the months before relapse were not significantly prognostic for subsequent survival with the possibly chance exception of mood at the second month before relapse. After relapse, physical well-being was statistically significantly associated with survival (P < 0.001). This prognostic significance increased in later post-relapse assessments. Similar findings were observed using patient-reported indicators for nausea and vomiting, appetite, coping effort, and health perception.

Conclusions

Before cancer relapse, QL indicators were not generally prognostic for subsequent survival. After relapse, QL indicators substantially predicted OS, with a stronger association later in the course of relapsed disease. Simple patient perception of disease burden seems unlikely to explain this sudden change: rather the patient’s awareness of disease relapse must contribute.

Predictors of quality of life among ethnically diverse breast cancer survivors

PURPOSE

Few studies have examined predictors of quality of life (QOL) of breast cancer survivors over time.

METHODS

Breast cancer survivors (n=116) were asked to complete measures of QOL, mood, spirituality, and social support every 6 months from 2-4 years post treatment.

RESULTS

Overall QOL at 4 years was predicted by previous physical and functional well-being, the breast cancer-specific items, and vigor and current levels of social support (Adj R²=.72, F=30.53, p<.001). Physical QOL was predicted by previous levels of physical and functional well- being and current levels of functional and social/family well-being (Adj R²=.84, F=44.30, p<.001). Functional well- being was predicted by prior levels of physical, functional, and social/family well-being and current levels of physical well-being and vigor (Adj R²=.72, F=3-.53, p<.001). Emotional well-being was predicted by previous levels of emotional well-being and current physical well-being, the breast cancer-specific items, and anxiety (Adj R²=.60, F=26.30, p<.001). Social/family well-being was predicted by previous levels of social/family well-being, social support, and confusion (Adj R²=.71, F=34.18, p<<000). The breast cancer-specific items were predicted by age, previous levels of the breast cancer-specific items, confusion and current levels of emotional and functional well-being and spirituality (Adj R²=.58, F=17.57, p<.001).

CONCLUSIONS

Over all and specific dimensions of QOL at 4 years were predicted by different combinations of QOL, mood, and spirituality. Interventions should be tailored to which dimensions of QOL are affected and other types of QOL as well as social support, mood, and spirituality as coping mechanisms that influence the specific dimension of QOL affected.

A Content Analysis of Functional Recovery Strategies of Breast Cancer Survivors

Seventeen breast cancer survivors completed a 6-week, telephone-delivered, behavioral activation/problem-solving intervention designed to reduce participation restrictions. A content analysis of the session data was conducted to identify the goals and patterns of goal attainment and to understand what women were trying to achieve in their recovery. The 17 women set 141 goals. Sixty-six (47%) of the goals reflected a desire to add a new activity to their routine and 75 (53%) of the goals reflected a desire to perform a routine activity more efficiently. The women primarily set goals to address challenges in exercising (24%), work (13%), nutrition (12%), instrumental activities of daily living (IADLs; 10%), stress management (9%), and social activities (9%). The women set an average of 8 goals and met 71% of their goals. The intervention shows promise in helping women set and achieve a number of functional goals as part of breast cancer recovery.

Factors predicting adherence to risk management behaviors of women at increased risk for developing lymphedema

PURPOSE

Lymphedema affects 20-30% of women following breast cancer treatment. However, even when women are informed, they do not necessarily adhere to recommended lymphedema self-management regimens. Utilizing the Cognitive-Social Health Information Processing framework, we assessed the cognitive and emotional factors influencing adherence to lymphedema risk management.

METHODS

Women with breast cancer who had undergone breast and lymph node surgery were recruited through the Fox Chase Cancer Center breast clinic. Participants (N = 103) completed measures of lymphedema-related perceived risk, beliefs and expectancies, distress, self-regulatory ability to manage distress, knowledge, and adherence to risk management behaviors. They then received the American Cancer Society publication "Lymphedema: What Every Woman with Breast Cancer Should Know." Cognitive and affective variables were reassessed at 6 and 12 months post-baseline.

RESULTS

Maximum likelihood multilevel model analyses indicated that overall adherence increased over time, with significant differences between baseline and 6- and 12-month assessments. Adherence to wearing gloves was significantly lower than that for all other behaviors except electric razor use. Distress significantly decreased, and knowledge significantly increased, over time. Greater knowledge, higher self-efficacy to enact behaviors, lower distress, and higher self-regulatory ability to manage distress were associated with increased adherence.

CONCLUSIONS

Women who understand lymphedema risk management and feel confident in managing this risk are more likely to adhere to recommended strategies. These factors should be rigorously assessed as part of routine care to ensure that women have the self-efficacy to seek treatment and the self-regulatory skills to manage distress, which may undermine attempts to seek medical assistance.

Prevalence, intensity, and predictors of the supportive care needs of women diagnosed with breast cancer: a systematic review

OBJECTIVE

The assessment of supportive care needs is a crucial step in the development of appropriate interventions that may improve the quality of life of cancer patients. This review describes and analyzes the prevalence and predictors of the unmet supportive care needs of breast cancer (BC) patients and survivors and suggests paths for further research.

METHOD

Multiple databases were searched, considering only quantitative studies using validated needs assessment instruments and focusing uniquely on women diagnosed with BC.

RESULTS

Out of 761 hits, 23 studies answered to all eligibility criteria. Nineteen were cross-sectional, and the remaining four were longitudinal. Most included patients at different moments along the BC trajectory, from diagnosis to decades into survivorship, with the major proportion of patients under treatment. Only five concentrated on the posttreatment phase into extended survivorship. The concerns of women diagnosed with BC clustered around psychological and information needs, with the top concern being 'fear of the cancer returning'. Predictors of higher levels of needs included advanced disease stage, greater symptom burden, shorter time since diagnosis, higher levels of distress, and younger age. Prevalence differed between cultures with Asian women reporting greater information needs and lower psychological needs compared with Western women.

CONCLUSIONS

Revealing which needs BC patients consider most urgent and the factors related to greater needs will permit the development of improved and targeted supportive care. Future research should comprise longitudinal designs concentrating on women at specific moments along the BC trajectory for a dynamic understanding of these needs.

Exercise for health: a randomized, controlled trial evaluating the impact of a pragmatic, translational exercise intervention on the quality of life, function and treatment-related side effects following breast cancer

Exercise for Health was a randomized, controlled trial designed to evaluate two modes of delivering (face-to-face [FtF] and over-the-telephone [Tel]) an 8-month translational exercise intervention, commencing 6-weeks post-breast cancer surgery (PS). Outcomes included quality of life (QoL), function (fitness and upper body) and treatment-related side effects (fatigue, lymphoedema, body mass index, menopausal symptoms, anxiety, depression and pain). Generalised estimating equation modelling determined time (baseline [5 weeks PS], mid-intervention [6 months PS], post-intervention [12 months PS]), group (FtF, Tel, Usual Care [UC]) and time-by-group effects. 194 women representative of the breast cancer population were randomised to the FtF (n = 67), Tel (n = 67) and UC (n = 60) groups. There were significant (p < 0.05) interaction effects on QoL, fitness and fatigue with differences being observed between the treatment groups and the UC group. Trends observed for the treatment groups were similar. The treatment groups reported improved QoL, fitness and fatigue over time and changes observed between baseline and post-intervention were clinically relevant. In contrast, the UC group experienced no change, or worsening QoL, fitness and fatigue, mid-intervention. Although improvements in the UC group occurred by 12-months post-surgery, the change did not meet the clinically relevant threshold. There were no differences in other treatment-related side effects between groups. This translational intervention trial, delivered either FtF or Tel, supports exercise as a form of adjuvant breast cancer therapy that can prevent declines in fitness and function during treatment and optimise recovery post-treatment.

Upper-body morbidity following breast cancer treatment is common, may persist longer-term and adversely influences quality of life

BACKGROUND

Impairments in upper-body function (UBF) are common following breast cancer. However, the relationship between arm morbidity and quality of life (QoL) remains unclear. This investigation uses longitudinal data to describe UBF in a population-based sample of women with breast cancer and examines its relationship with QoL.

METHODS

Australian women (n=287) with unilateral breast cancer were assessed at three-monthly intervals, from six- to 18-months post-surgery (PS). Strength, endurance and flexibility were used to assess objective UBF, while the Disability of the Arm, Shoulder and Hand questionnaire and the Functional Assessment of Cancer Therapy-Breast questionnaire were used to assess self-reported UBF and QoL, respectively.

RESULTS

Although mean UBF improved over time, up to 41% of women revealed declines in UBF between six- and 18-months PS. Older age, lower socioeconomic position, treatment on the dominant side, mastectomy, more extensive lymph node removal and having lymphoedema each increased odds of declines in UBF by at least two-fold (p<0.05). Lower baseline and declines in perceived UBF between six- and 18-months PS were each associated with poorer QoL at 18-months PS (p<0.05).

CONCLUSIONS

Significant upper-body morbidity is experienced by many following breast cancer treatment, persisting longer term, and adversely influencing the QoL of breast cancer survivors.
