The symptom cluster of fatigue, pain, anxiety, and depression and the effect on the quality of life of women receiving treatment for breast cancer: a multicenter study

Investigation of the relationship among fatigue, self-efficacy and quality of life during chemotherapy in patients with breast, lung or gastrointestinal cancer

To explore the relationship between fatigue and self-efficacy, and quality of life (QoL) during chemotherapy of patients with breast, lung or gastrointestinal cancers. This study is a descriptive-correlational research. The study population comprised of patients with breast, lung and gastrointestinal cancer treated at the outpatient chemotherapy unit. Patients' self-efficacy and QoL were assessed using Functional Assessment of Chronic Illness Therapy-Fatigue scale and Strategies Used by Patients to Promote Health scale. The sample included 236 patients receiving chemotherapy for lung cancer (30.9%), gastrointestinal (25.8%) or breast cancers (25.4%). The patients had little confidence in performing self-care self-efficacy during chemotherapy for the management of illness and chemotherapy-related side effects. The study found that the patients with cancer were moderately fatigued and all the domains of QoL of patients with cancer undergoing chemotherapy were considerably impaired. Positive correlations were found between self-efficacy scores and fatigue scores (p < 0.001), and QoL scores (p < 0.001). Better self-efficacy beliefs were associated with better QoL and lower fatigue. Improving the cancer patients' self-confidence in performing self-care behaviours may have a positive impact on performing cognitive and behavioural fatigue management strategies and can influence positively the patients' QoL during chemotherapy.

Symptom Clusters in Patients With Pancreatic Cancer Undergoing Surgical Resection: Part II

OBJECTIVES

To explore the relationship between 16 symptom clusters (SCs), clinical and demographic influencing factors, and clinical outcomes over time in patients with pancreatic cancer (PC) undergoing surgical resection.

SAMPLE & SETTING

143 patients with stage II PC undergoing surgical resection were recruited to participate in this longitudinal, exploratory study conducted at Thomas Jefferson University Hospital, a National Cancer Institute-designated cancer center.

METHODS & VARIABLES

Quality of life was measured preoperatively and at three, six, and nine months postoperatively. Statistical methods included simple linear and Cox proportional hazard regression.

RESULTS

Preoperative pain was significantly associated with the pain-gastrointestinal SC, and preoperative worry was significantly associated with the mood SC. The strongest negative association with emotional well-being across all study time points was found with the preoperative mood SC. The insomnia-digestive problems SC and the nutritional problems SC demonstrated a trend toward poor survival.

IMPLICATIONS FOR NURSING

Findings provide evidence that preoperative worry and pain are associated with SC severity and that SCs may have a detrimental effect on quality of life and survival in patients with PC undergoing surgical resection.

Effect of neuromuscular electrical stimulation for fatigue management in patients with advanced laryngeal cancer receiving chemoradiotherapy

This study retrospectively investigated the effect of neuromuscular electrical stimulation (NMES) for fatigue management in patients with advanced laryngeal cancer (ALC) receiving chemoradiotherapy.A total of 60 eligible patients with ALC receiving chemoradiotherapy were included. These patients were assigned equally to a treatment group and a control group. Patients in the treatment group received NMES therapy and were treated for a total of 8 weeks, while the patients in the control group did not receive NMES therapy. The primary outcome was fatigue, measured by the multidimensional fatigue inventory (MFI). The secondary outcomes included anxiety and depression, measured by the Hospital Anxiety and Depression Scale (HADS), and sleep quality, measured by the Pittsburgh Sleep Quality Index (PSQI). All outcomes were evaluated before and after 8-week NMES treatmentAfter 8-week NMES treatment, the patients in the treatment group did not exert better effect than patients in the control group in fatigue relief, measured by the MFI score, anxiety and depression decrease, assessed by HADS, and sleep quality improvement, evaluated by PSQI.The results of this study demonstrate that NMES may not benefit for fatigue relief in patients with ALC receiving chemoradiotherapy. Future studies should still focus on this topic and warrant these results.

Quality of Sleep and Coexistent Psychopathology Have Significant Impact on Fatigue Burden in Patients With Inflammatory Bowel Disease

BACKGROUND

Fatigue is common in inflammatory bowel disease (IBD) patients and is associated with factors such as psychopathology, sleep quality, and disease activity.

GOAL

To investigate the combined role of all the above factors in the burden of fatigue among IBD patients.

STUDY

We conducted an observational study of adult patients enrolled in an IBD clinical research registry at a tertiary care clinic. Fatigue burden was defined by Item 1 of the Short-form IBD Questionnaire (SIBDQ), which is scored on a 7-point Likert scale. Crohn's disease (CD) and ulcerative colitis (UC) disease activity were measured with the Harvey-Bradshaw Index or the UC Activity Index, respectively. Labs were obtained to assess anemia, vitamin deficiencies, and inflammatory markers. Sleep quality was assessed using the Pittsburgh Sleep Quality Index (PSQI). Use of psychotropic medications and narcotics was used as proxy measure of psychopathology and pain.

RESULTS

Among 685 IBD patients enrolled in the registry, 631 (238 UC, 393 CD) had a complete SIBDQ. High fatigue burden was found in 57.5% of patients (64.4% CD, 46.2% UC). Fatigue burden was significantly associated with sleep disturbance (PSQI), SIBDQ, and disease activity. CD patients had more fatigue burden than UC patients. Multivariate regression showed that poor quality of life, sleep disturbance, and being on a psychotropic medication are significantly associated with fatigue burden for both UC and CD.

CONCLUSION

Because fatigue is common in IBD patients, these findings suggest that attention to quality of sleep and psychopathology is as important as medical disease management.

Mobile Breast Cancer e-Support Program for Chinese Women With Breast Cancer Undergoing Chemotherapy (Part 2): Multicenter Randomized Controlled Trial

Background

Women undergoing chemotherapy for the treatment of breast cancer have frequently reported unmet supportive care needs. Moreover, easily accessible and innovative support is lacking.

Objective

The purpose of this trial was to determine the effectiveness of an app-based breast cancer e-support program to address women’s self-efficacy (primary outcome), social support, symptom distress, quality of life, anxiety, and depression. Secondary objectives included exploring the association between women’s health outcomes and the breast cancer e-support usage data.

Methods

A multicenter, single-blinded, randomized controlled trial was conducted. A total of 114 women with breast cancer, who were commencing chemotherapy and were able to access internet through a mobile phone, were recruited in the clinics from 2 university-affiliated hospitals in China. Women were randomized either to the intervention group (n=57) receiving breast cancer e-support plus care as usual or the control group (n=57) receiving care as usual alone. The health care team and research assistants collecting data were blinded to the women’s group allocation. Bandura’s self-efficacy theory and the social exchange theory guided the development of the breast cancer e-support program, which has 4 components: (1) a Learning forum, (2) a Discussion forum, (3) an Ask-the-Expert forum, and (4) a Personal Stories forum. Moderated by an experienced health care professional, the breast cancer e-support program supported women for 12 weeks covering 4 cycles of chemotherapy. Health outcomes were self-assessed through paper questionnaires in clinics at baseline before randomization (T0), after 3 (T1), and 6 months (T2) of follow-ups.

Results

Fifty-five participants in the intervention group and 49 in the control group completed the follow-up assessments (response rate: 91.2%). During the 12-week intervention, the log-in frequency ranged from 0 to 774 times (mean 54.7; SD 131.4; median 11; interquartile range, IQR 5-27), and the total usage duration ranged from 0 to 9371 min (mean 1072.3; SD 2359.5; median 100; IQR 27-279). Repeated measures multivariate analysis of covariance (intention-to-treat) found that breast cancer e-support + care as usual participants had significant better health outcomes at 3 months regarding self-efficacy (21.05; 95% CI 1.87-40.22; P=.03; d=0.53), symptom interference (−0.73; 95% CI −1.35 to −.11; P=.02; d=−0.51), and quality of life (6.64; 95% CI 0.77-12.50; P=.03, d=0.46) but not regarding social support, symptom severity, anxiety, and depression compared with care as usual participants. These beneficial effects were not sustained at 6 months. Spearman rank-order correlation showed that the breast cancer e-support usage duration was positively correlated with self-efficacy (r=.290, P=.03), social support (r=.320, P=.02), and quality of life (r=.273, P=.04) at 3 months.

Conclusions

The breast cancer e-support program demonstrated its potential as an effective and easily accessible intervention to promote women’s self-efficacy, symptom interference, and quality of life during chemotherapy.

Health-related quality of life in Asian patients with breast cancer: a systematic review

OBJECTIVE

To summarise the evidence on determinants of health-related quality of life (HRQL) in Asian patients with breast cancer.

DESIGN

Systematic review conducted according to the Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) recommendations and registered with PROSPERO (CRD42015032468).

METHODS

According to the PRISMA guidelines, databases of MEDLINE (PubMed), Embase and PsycINFO were systematically searched using the following terms and synonyms: breast cancer, quality of life and Asia. Articles reporting on HRQL using EORTC-QLQ-C30, EORTC-QLQ-BR23, FACT-G and FACT-B questionnaires in Asian patients with breast cancer were eligible for inclusion. The methodological quality of each article was assessed using the quality assessment scale for cross-sectional studies or the Newcastle-Ottawa Quality Assessment Scale for cohort studies.

RESULTS

Fifty-seven articles were selected for this qualitative synthesis, of which 43 (75%) were cross-sectional and 14 (25%) were longitudinal studies. Over 75 different determinants of HRQL were studied with either the EORTC or FACT questionnaires. Patients with comorbidities, treated with chemotherapy, with less social support and with more unmet needs have poorer HRQL. HRQL improves over time. Discordant results in studies were found in the association of age, marital status, household income, type of surgery, radiotherapy and hormone therapy and unmet sexuality needs with poor global health status or overall well-being.

CONCLUSIONS

In Asia, patients with breast cancer, in particular those with other comorbidities and those treated with chemotherapy, with less social support and with more unmet needs, have poorer HRQL. Appropriate social support and meeting the needs of patients may improve patients' HRQL.

Integration of Massage Therapy in Outpatient Cancer Care

BACKGROUND

Massage therapy can be helpful in alleviating cancer-related symptoms and cancer treatment-related symptoms. While surveys have noted that cancer patients seek out massage as a nonpharmacologic approach during cancer treatment, little is known about the integration of massage in outpatient cancer care.

PURPOSE

The purpose of this study was to examine the extent to which massage is being integrated into outpatient cancer care at NCI-designated Cancer Centers.

SETTING

This study used descriptive methods to analyze the integration of massage in NCI-designated Cancer Centers providing clinical services to patients (n = 62).

DESIGN

Data were collected from 91.1% of the centers (n = 59) using content analysis and a telephone survey. A dataset was developed and coded for analysis.

MAIN OUTCOME MEASURE

The integration of massage was assessed by an algorithm that was developed from a set of five variables: 1) acceptance of treatment as therapeutic, 2) institution offers treatment to patients, 3) clinical practice guidelines in place, 4) use of evidence-based resources to inform treatment, and 5) shared knowledge about treatment among health care team. All centers were scored against all five variables using a six-point scale, with all variables rated equally.

RESULTS

The integration of massage ranged from not at all (0) to very high (5) with all five levels of integration evident. Only 11 centers (17.7% of total) rated a very high level of integration; nearly one-third of the centers (n = 22) were found to have no integration of massage at all-not even provision of information about massage to patients through the center website.

CONCLUSIONS

The findings of this analysis suggest that research on massage is not being leveraged to integrate massage into outpatient cancer care.

In Schizophrenia, Depression, Anxiety, and Physiosomatic Symptoms Are Strongly Related to Psychotic Symptoms and Excitation, Impairments in Episodic Memory, and Increased Production of Neurotoxic Tryptophan Catabolites: a Multivariate and Machine Learning Study

The depression, anxiety and physiosomatic symptoms (DAPS) of schizophrenia are associated with negative symptoms and changes in tryptophan catabolite (TRYCAT) patterning. The aim of this study is to delineate the associations between DAPS and psychosis, hostility, excitation, and mannerism (PHEM) symptoms, cognitive tests as measured using the Consortium to Establish a Registry for Alzheimer's Disease (CERAD) and IgA/IgM responses to TRYCATs. We included 40 healthy controls and 80 participants with schizophrenia. Depression and anxiety symptoms were measured with The Hamilton Depression (HAM-D) and Anxiety (HAM-A) Rating Scales, respectively. Physiosomatic symptoms were assessed with the Fibromyalgia and Chronic Fatigue Syndrome Rating Scale (FF). Negative symptoms as well as CERAD tests, including Verbal Fluency Test (VFT), Mini-Mental State Examination (MMSE), Word List Memory (WLM), and WL Delayed Recall were measured, while ratios of IgA responses to noxious/protective TRYCATs (IgA NOX_PRO) were computed. Schizophrenia symptoms consisted of two dimensions, a first comprising PHEM and negative symptoms, and a second DAPS symptoms. A large part of the variance in DAPS was explained by psychotic symptoms and WLM. Of the variance in HAM-D, 58.9% was explained by the regression on excitement, IgA NOX_PRO ratio, WLM, and VFT; 29.9% of the variance in HAM-A by psychotic symptoms and IgA NOX/PRO; and 45.5% of the variance in FF score by psychotic symptoms, IgA NOX/PRO, and WLM. Neural network modeling shows that PHEM, IgA NOX_PRO, WLM, and MMSE are the dominant variables predicting DAPS. DAPS appear to be driven by PHEM and negative symptoms coupled with impairments in episodic memory, especially false memory creation, while all symptom dimension and cognitive impairments may be driven by an increased production of noxious TRYCATs, including picolinic, quinolinic, and xanthurenic acid.

Symptoms Experienced and Information Needs of Women Receiving Chemotherapy

Objective:

This study is carried out to determine the symptoms and information necessity on chemotherapy (CT) treatment of the women with breast cancer.

Methods:

A total of 170 women older than 18 years old, who receive CT with breast cancer diagnosis, are volunteered to participate in the study. Mixed method was used in the study. Data are collected using Descriptive Data Form, Interview Form and Memorial Symptom Assessment Scale.

Results:

As a result of the cluster analysis, four clusters and the symptoms within have been obtained. These are: pain, lack of energy, feeling drowsy, sweat, swelling of hands, and feet in the first cluster; feeling nervous, difficulty sleeping, feeling sad, worrying in the second cluster; nausea, feeling bloating, change in the way food tastes, hair loss, constipation in the third cluster; vomiting, diarrhea, problems with sexual interest, lack of appetite, dizziness, and weight loss in the forth cluster. Women's information necessity related to the CT are follows: the effects of CT, other treatment options beyond CT, complementary methods, the effect of the CT treatment on reproductive health and sexuality, nutrition, and symptom control.

Conclusions:

The results of this study will enable determination of symptom clusters, which health professionals are easier to focus on these symptoms. An understanding information need of patients can help to ensure that individual's coping strategies and self-management.

Treatment-Related Quality of Life in Nepalese Women with Breast Cancer

Objective:

To identify the level of quality of life and its predictors in Nepalese women with breast cancer while receiving chemotherapy.

Methods:

This cross-sectional study with a predictive design was conducted for a conveniently selected sample of 85 Nepalese women with primary breast cancer receiving chemotherapy at outpatient clinics of three cancer hospitals of Kathmandu, Nepal. Data were collected during December 2016 and February 2017 using demographic sheets, the European Organization for Research and Treatment of Cancer Quality of Life Core Questionnaire and the modified Medical Outcomes Study Social Support Survey. Descriptive and inferential statistics were employed for data analysis.

Results:

The mean age of the sample was 50.2 years (SD = 11.50). Study participants reported moderate to poor quality of life (M = 33.5, SD = 23.5). Multiple regression analysis showed that age, years of education, stage, past breast surgery, overall symptom severity, and social support significantly explained 56.8% of the variance in quality of life (R² = .568, F (8,76) = 12.469, p = .000). However, overall symptom severity (β = -.477, p= .000) and social support (β = .183, p = .050) were the most important predictors.

Conclusions:

As Nepalese women reported decreased quality of life, nurses should provide preventive and supportive services to improve the quality of life of their patients during chemotherapy.

Cognition, quality-of-life, and symptom clusters in breast cancer: Using Bayesian networks to elucidate complex relationships

OBJECTIVE

Breast cancer patients frequently complain of cognitive dysfunction during chemotherapy. Patients also report experiencing a cluster of sleep problems, fatigue, and depressive symptoms during chemotherapy. We aimed to understand the complex dynamic interrelationships of depression, fatigue, and sleep to ultimately elucidate their role in cognitive performance and quality of life amongst breast cancer survivors undergoing chemotherapy treatment.

METHODS

Our study sample comprised 74 newly diagnosed stage I to III breast cancer patients scheduled to receive chemotherapy. An objective neuropsychological test battery and self-reported fatigue, mood, sleep quality, and quality of life were collected at 3 time points: before the start of chemotherapy (baseline: BL), at the end of cycle 4 chemotherapy (C4), and 1 year after the start of chemotherapy (Y1). We applied novel Bayesian network methods to investigate the role of sleep/fatigue/mood on cognition and quality of life prior to, during, and after chemotherapy.

RESULTS

The fitted network exhibited strong direct and indirect links between symptoms, cognitive performance, and quality of life. The only symptom directly linked to cognitive performance was C4 sleep quality; at C4, fatigue was directly linked to sleep and thus indirectly influenced cognitive performance. Mood strongly influenced concurrent quality of life at C4 and Y1. Regression estimates indicated that worse sleep quality, fatigue, and mood were negatively associated with cognitive performance or quality of life.

CONCLUSIONS

The Bayesian network identified local structure (eg, fatigue-mood-QoL or sleep-cognition) and possible intervention targets (eg, a sleep intervention to reduce cognitive complaints during chemotherapy).

.

IMPLICATIONS FOR NURSING

Identification of women at risk for fatigue and disturbed sleep may allow clinicians to intensify symptom management.

Anxiety, Depression and Quality of Life in Breast Cancer Patients in the Levant

Background:

Limited data are currently available regarding the psychological well-being and quality of life of breast cancer patients after active treatment in Lebanon and the Arab region in general. The objective of this study was to determine the prevalence of anxiety and depression among Arab breast cancer patients and assess the quality of life with reference to socio-demographic and clinical characteristics.

Methods:

This cross-sectional study was conducted among female breast cancer patients diagnosed between January 2009 and March 2014, who were recruited from the outpatient clinics of Naef K. Basile Cancer Institute at the American University of Beirut Medical Center (AUBMC) from November 2015 till December 2016. An interview was conducted utilizing two validated questionnaires: the Hospital Anxiety and Depression Scale (HADS) and the Functional Assessment of Cancer Therapy-Breast (FACT-B). Socio-demographic and clinical characteristics that might predict patient quality of life were collected and summarized.

Results:

A total of 150 patients were interviewed (median age 53.5±10.4 years). Most were assessed 3 to 5 years (68.7%) after initial diagnosis and had undergone surgery, chemotherapy, radiation, or hormonal therapy (97.3%, 79.3%, 80.7% and 86.0%, respectively). The median total HADS score was 10.0 ± 8.0, with approximately 41.3% of study participants having abnormal scores on the anxiety subscale and 24.7% on the depression subscale. Significant predictors of total HADS score were nationality and level of education (p=0.001, p=0.001 respectively; R²=0.181). Participants who were Iraqi, had stage IV disease, had a household monthly income below 1000 USD, or had received chemotherapy exhibited significantly lower total FACT-B scores, these being highly negatively correlated with total HADS scores (r_s= -0.73, p=0.001).

Conclusion:

There is a vital need for the development of individualized interventions and psychosocial support programs tailored to the physical and psychological well-being of breast cancer patients in the Levant region.

Cancer Impact, Complementary/Alternative Medicine Beliefs, and Quality of Life in Cancer Patients

OBJECTIVES

The purpose of this study was to explore the relationships among cancer impact, belief in complementary and alternative medicine (CAM), CAM use, and quality of life (QOL).

DESIGN

The study used a cross-sectional, descriptive correlational design with convenience sampling. A total of 122 cancer patients participated. Data were collected at a medical center in Chunghua, Taiwan. The questionnaires included the Chinese version of the Cancer Problem in Living Scale (CPILS), Complementary and Alternative Medicine Belief Inventory (CAMBI), Complementary and Alternative Medicine scale, and Chinese versions of QOL scales, including the Functional Assessment of Cancer Therapy-General (FACT-G).

RESULTS

The mean age was 56.5 years, and most participants were male (n = 69, 56.6%), had completed high school or above (n = 56, 45.9%), and were married (n = 109, 89.3%). The most common type of cancer was oral (n = 17, 13.9%), followed by esophageal (n = 15, 12.3%) and colorectal (n = 13, 10.7%). Cancer patients, on average, use one or two types of CAM. The impact of cancer is significantly related to age (F = 7.12, p < 0.05), and income is related to QOL (F = 3.61, p < 0.05). Pearson correlations showed that the use of CAM was positively associated with belief in CAM (CAMBI) (r = 0.26, p = 0.01), and the impact of cancer was highly negatively associated with QOL (r = -0.71, p = 0.001). The predictors of QOL were the impact of cancer and use of CAM, and the impact of cancer accounted for 51% of the variance in QOL.

CONCLUSION

This study supports research on the impact of cancer, belief in CAM, and use of CAM as related to QOL in cancer patients. These results can be used to provide options to clinicians and cancer patients.

Effect of therapeutic care for treating fatigue in patients with breast cancer receiving chemotherapy

BACKGROUND

This study aimed to evaluate the effect of therapeutic care (TC) for fatigue in breast cancer patients receiving chemotherapy.

METHODS

A total of 48 breast cancer patients receiving chemotherapy were randomly divided into the intervention group and the control group, with 24 patients in each group. The patients in the intervention group were treated with TC, while the participants in the control group received the sham intervention. The interventions in both groups were for 30 min/d, 3 days weekly for 12 weeks. The primary outcome of fatigue was measured by the multidimensional fatigue inventory (MFI). The secondary outcomes were measured by the Hospital Anxiety and Depression Scale (HADS) and Pittsburgh Sleep Quality Index (PSQI). All outcomes were assessed before and after 6 and 12 weeks of the intervention.

RESULTS

The intervention with TC showed greater efficacy than sham TC in decreasing the MFI score after week 6 (P < .05) and week 12 (P < .01) of treatment. Significant differences were also found in the HADS and PSQI between the 2 groups after 12 weeks of treatment (P < .01).

CONCLUSION

This study demonstrated that TC might decrease fatigue and relieve the anxiety and depression of breast cancer patients receiving chemotherapy.

Physio-somatic symptoms in schizophrenia: association with depression, anxiety, neurocognitive deficits and the tryptophan catabolite pathway

To investigate the frequency of physio-somatic symptoms (PS) symptoms in schizophrenia and their relation to positive, negative and affective symptoms; neurocognitive deficits and impairments in the tryptophan catabolite (TRYCAT) pathway. Eighty four patients with schizophrenia and 40 healthy controls were assessed using the 12 item Fibromyalgia and Chronic Fatigue Syndrome Rating scale (FF) and scales for negative and positive symptoms, depression and anxiety. Cognitive functioning was tested using the Cambridge Neuropsychological Test Automated Battery (CANTAB). Other assessments included: immunoglobulin (Ig)A and IgM responses to tryptophan catabolites (TRYCATs), namely quinolinic (QA), 3-OH-kynurenine (3HK), picolinic (PA), xanthurenic (XA) and kynurenic acid (KA) and anthranilic acid (AA). More than 50% of the patients studied had elevated levels of physio-somatic (PS) symptoms, significantly co-occurring with depression and anxiety, but not with negative or positive symptoms. PS symptoms were significantly associated with IgA/IgM responses to TRYCATs, including increased IgA responses to 3 HK, PA and XA, and lowered IgA to QA and AA. Fatigue, muscle pain and tension, autonomic and cognitive symptoms and a flu-like malaise were strongly associated with cognitive impairments in spatial planning and working memory, paired associative learning, visual sustained attention and attention set shifting. PS symptoms in schizophrenia aggregate with depression and anxiety symptoms and may be driven by TRYCAT patterning of IgA/IgM-responses, with IgA indicating mucosal-mediated changes and IgM indicating regulatory functions. As such, the patterning of IgA/IgM responses to TRYCATs may indicate differential TRYCATs regulation of neuronal and glia activity that act to regulate PS signalling in schizophrenia.

Taltirelin alleviates fatigue-like behavior in mouse models of cancer-related fatigue

Fatigue affects most cancer patients and has numerous potential causes, including cancer itself and cancer treatment. Cancer-related fatigue (CRF) is not relieved by rest, can decrease quality of life, and has no FDA-approved therapy. Thyrotropin-releasing hormone (TRH) has been proposed as a potential novel treatment for CRF, but its efficacy against CRF remains largely untested. Thus, we tested the TRH analog, taltirelin (TAL), in mouse models of CRF. To model fatigue, we used a mouse model of chemotherapy, a mouse model of radiation therapy, and mice bearing colon 26 carcinoma tumors. We used the treadmill fatigue test to assess fatigue-like behavior after treatment with TAL. Additionally, we used wild-type and TRH receptor knockout mice to determine which TRH receptor was necessary for the actions of TAL. Tumor-bearing mice displayed muscle wasting and all models caused fatigue-like behavior, with mice running a shorter distance in the treadmill fatigue test than controls. TAL reversed fatigue-like behavior in all three models and the mouse TRH₁ receptor was necessary for the effects of TAL. These data suggest that TAL may be useful in alleviating fatigue in all cancer patients and provide further support for evaluating TAL as a potential therapy for CRF in humans.

Symptom assessment in non-vocal or cognitively impaired ICU patients: Implications for practice and future research

BACKGROUND

Symptom assessment in critically ill patients is challenging because many cannot provide a self-report.

OBJECTIVES

To describe the state of the science on symptom communication and the assessment of selected physical symptoms in non-vocal ICU patients.

METHODS

This paper summarizes a 2014 American Thoracic Society Annual International Conference symposium presenting current evidence on symptom communication, delirium, and the assessment of common physical symptoms (i.e., dyspnea, pain, weakness, and fatigue) experienced by non-vocal ICU patients.

RESULTS

Symptom assessment begins with accurate assessment, which includes an evaluation of delirium, and assistance in symptom communication. Simple self-report measures (e.g., 0-10 numeric rating scale), observational measures (e.g., Respiratory Distress Observation Scale and Critical-Care Pain Observation Tool), or objective measures (e.g., manual muscle testing and hand dynamometry) have demonstrated utility among this population.

CONCLUSION

Optimizing symptom assessment with valid and reliable instruments with minimum patient burden is necessary to advance clinical practice and research in this field.

Effects of paclitaxel on the development of neuropathy and affective behaviors in the mouse

Paclitaxel, one of the most commonly used cancer chemotherapeutic drugs, effectively extends the progression-free survival of breast, lung, and ovarian cancer patients. However, paclitaxel and other chemotherapy drugs elicit peripheral nerve fiber dysfunction or degeneration that leads to peripheral neuropathy in a large proportion of cancer patients. Patients receiving chemotherapy also often experience changes in mood, including anxiety and depression. These somatic and affective disorders represent major dose-limiting side effects of chemotherapy. Consequently, the present study was designed to develop a preclinical model of paclitaxel-induced negative affective symptoms in order to identify treatment strategies and their underlying mechanisms of action. Intraperitoneal injections of paclitaxel (8 mg/kg) resulted in the development and maintenance of mechanical and cold allodynia. Carboplatin, another cancer chemotherapeutic drug that is often used in combination with paclitaxel, sensitized mice to the nociceptive effects of paclitaxel. Paclitaxel also induced anxiety-like behavior, as assessed in the novelty suppressed feeding and light/dark box tests. In addition, paclitaxel-treated mice displayed depression-like behavior during the forced swim test and an anhedonia-like state in the sucrose preference test. In summary, paclitaxel produced altered behaviors in assays modeling affective states in C57BL/6J male mice, while increases in nociceptive responses were longer in duration. The characterization of this preclinical model of chemotherapy-induced allodynia and affective symptoms, possibly related to neuropathic pain, provides the basis for determining the mechanism(s) underlying severe side effects elicited by paclitaxel, as well as for predicting the efficacy of potential therapeutic interventions.

Polypharmacy and Adherence to Adjuvant Endocrine Therapy for Breast Cancer

PURPOSE

Many patients with breast cancer are treated for other conditions and experience polypharmacy with multiple concurrent medications. Our aim was to evaluate polypharmacy in relation to adherence to adjuvant endocrine therapy (AET) in breast cancer.

METHODS

We conducted a retrospective cohort study of women with incident, invasive breast cancer initiating AET (tamoxifen, letrozole, anastrozole, exemestane) between 2009 and 2013 in the Truven Health MarketScan Database. Polypharmacy and pill burden were measured for commonly used concurrent medications, including lipid-lowering drugs, antihypertensives, oral diabetes medications, insulin analogs, antidepressants, anxiolytics/antipsychotics, and opioid-containing analgesics. Polypharmacy was defined as frequent use (three or more dispensings) of a given medication class and by pill burden (total dispensings). Medication possession ratios (MPR) were estimated for subsequent 12-month intervals. Multivariable generalized estimating equation models were used to calculate odds ratios (ORs) and robust 95% CIs for associations with AET adherence (MPR ≥ 0.80).

RESULTS

Among 40,009 women, 74% were adherent in year +1 and continued to have high mean adherence (MPR = 0.79) among those continuing AET through year +3. Increasing polypharmacy ( P < .001) and pill burden ( P < .001) were associated with greater adherence, but effects differed by medication class. Frequent use of lipid-lowering drugs (OR, 1.42; 95% CI, 1.36 to 1.49) and antihypertensives (OR, 1.15; 95% CI, 1.10 to 1.20) were associated with higher odds of adherence; frequent use of opioid-containing analgesics (OR, 0.80; 95% CI, 0.77 to 0.83), anxiolytics/antipsychotics (OR, 0.95; 95% CI, 0.91 to 0.99), antidepressants (OR, 0.85; 95% CI, 0.82 to 0.89), and insulin therapy (OR, 0.82; 95% CI, 0.72 to 0.95) were associated with lower odds of adherence.

CONCLUSION

Associations between polypharmacy and adherence in breast cancer may be better characterized by understanding specific classes of medications used concurrently. Comprehensive medication therapy management, including ongoing pain evaluation and psychoactive therapies, is warranted.

Depressive symptoms and positive affect in Chinese and United States breast cancer survivors: a cross-cultural comparison

PURPOSE

Research in the area of cultural response pattern on questionnaires in the oncological setting and direct cross-cultural comparisons are lacking. This study examined response pattern in the reporting of depressive symptoms in Chinese and US women with breast cancer. We hypothesized that Chinese women are less likely to endorse positive affect items compared to their US counterparts. Additionally, we explored cultural differences in the association between positive affect and QOL.

METHODS

Secondary analyses of baseline assessments of two mind-body intervention studies for women with breast cancer undergoing radiotherapy in the USA (N = 62) and China (N = 97) are presented. All participants completed measures of depressive symptoms (CES-D) and cancer-specific QOL (FACT-B). We examined cultural differences on positive and negative affect items on the CES-D.

RESULTS

Controlling for demographic factors, ANCOVA revealed a significant cultural difference in positive (F = 7.99, p = 0.005) but not negative affect (p = 0.82) with Chinese women reporting lower positive affect compared to US women (Chinese = 6.97 vs. US = 8.31). There was also a significant cultural difference (F = 3.94, p = 0.03) in the association between positive affect and QOL so that lower positive affect was more strongly associated with worse emotional well-being in Chinese (beta = 0.57, p < 0.0001) than US women (beta = 0.35, p < 0.01).

CONCLUSIONS

Chinese women reported lower positive affect compared to US women and lower levels of positive affect were more strongly associated with worse QOL. Special attention is needed when examining mental health in different cultures to ascertain effective delivery of clinical services to those in need.

Complementary and alternative medicine use among patients with cancer in Mongolia: a National hospital survey

Background

Complementary and alternative medicine (CAM) use is popular in former Soviet Central Asian countries including Mongolia. However, no studies are available on CAM use among patients with cancer in countries of this region. The aim of this research is to describe the prevalence and patterns of CAM use by patients with cancer in Mongolia.

Methods

A cross-sectional study was conducted using data from 482 cancer patients attending the National Cancer Center in Mongolia from September 2015 to February 2016. The survey instrument included 25 questions regarding CAM used, factors associated with use of CAM, cancer-related characteristics, and participants’ socio-demographic profile.

Results

Among 482 respondents (response rate, 95.6%), 47.9% reported using one or more CAM modalities. Products of animal origin were the most popular modalities of CAM, followed by herbal products. Half of the users used CAM while receiving conventional treatment of cancer. Among users, only 29% discussed the CAM use with their doctors. Female gender, younger age, higher education, shorter disease duration, and prior use of CAM were significantly associated with CAM use.

Conclusions

CAM appears to be widely accepted by patients with cancer in Mongolia. The findings support the urgent need for further in-depth study into commonly used oral CAM products and their potential effects on health of patients with cancer in Mongolia. High prevalence of CAM use among cancer patients in our study warrants further studies in other countries of Central Asia.

Depression and family support in breast cancer patients

BACKGROUND

Breast cancer is the most common cancer in women. Among the survivors, depression is one of the most common psychiatric comorbidities. This paper reports the point prevalence of major depressive disorder among breast cancer patients and the association between family support and major depressive disorder.

METHODS

Clinical data were collected from a breast cancer clinic of a general hospital in central Taiwan. Participants included 300 patients who were older than 18 years and diagnosed with breast cancer. Among these individuals, we used Mini International Neuropsychiatric Interview (a structural diagnostic tool for psychiatric disorders) to ascertain if they had major depressive disorder. We also used the Family Adaptability, Partnership, Growth, Affection, and Resolve score to assess the family support.

RESULTS

The point prevalence of major depressive disorder among breast cancer patients was 8.33%, and this was positively associated with insomnia, psychiatric family history, pain severity, and radiotherapy and negatively associated with menopause, cancer duration, hormone therapy, and family support. Family support (adjusted odds ratio =0.87, 95% CI: 0.78-0.98) was found to be an associated factor for major depressive disorder in breast cancer patients after controlling for potential risk factors.

CONCLUSION

Major depressive disorder is a common comorbidity among breast cancer patients. Family support is an important associated factor for these patients. Health care professionals should evaluate mood problems and family support while treating these patients.

An Analysis and Evaluation of the Theory of Unpleasant Symptoms

The Theory of Unpleasant Symptoms was developed to enhance understanding of relationships among multiple symptoms and symptom experiences. Although the theory has been used to guide research, no formal critique of the theory has been published since 2000. This article comprehensively analyzes and evaluates the theory using Fawcett and DeSanto-Madeya's framework. Although its semantic clarity, semantic and structural consistency, and parsimony could be improved, the theory demonstrates good social and theoretical significance, testability, and empirical and pragmatic adequacy. Understanding multiple patient symptoms is essential, and the theory demonstrates that nurses should focus on multiple rather than individual symptoms.

Associations Between Neurotransmitter Genes and Fatigue and Energy Levels in Women After Breast Cancer Surgery

CONTEXT

Fatigue is a common problem in oncology patients. Less is known about decrements in energy levels and the mechanisms that underlie both fatigue and energy.

OBJECTIVES

In patients with breast cancer, variations in neurotransmitter genes between lower and higher fatigue latent classes and between the higher and lower energy latent classes were evaluated.

METHODS

Patients completed assessments before and monthly for six months after surgery. Growth mixture modeling was used to identify distinct latent classes for fatigue severity and energy levels. Thirty candidate genes involved in various aspects of neurotransmission were evaluated.

RESULTS

Eleven single-nucleotide polymorphisms or haplotypes (i.e., ADRB2 rs1042718, BDNF rs6265, COMT rs9332377, CYP3A4 rs4646437, GALR1 rs949060, GCH1 rs3783642, NOS1 rs9658498, NOS1 rs2293052, NPY1R Haplotype A04, SLC6A2 rs17841327, and 5HTTLPR + rs25531 in SLC6A4) were associated with latent class membership for fatigue. Seven single-nucleotide polymorphisms or haplotypes (i.e., NOS1 rs471871, SLC6A1 rs2675163, SLC6A1 Haplotype D01, SLC6A2 rs36027, SLC6A3 rs37022, SLC6A4 rs2020942, and TAC1 rs2072100) were associated with latent class membership for energy. Three of 13 genes (i.e., NOS1, SLC6A2, and SLC6A4) were associated with latent class membership for both fatigue and energy.

CONCLUSIONS

Molecular findings support the hypothesis that fatigue and energy are distinct, yet related symptoms. Results suggest that a large number of neurotransmitters play a role in the development and maintenance of fatigue and energy levels in breast cancer patients.

Differences in quality of life between American and Chinese breast cancer survivors

OBJECTIVE

It has been speculated that cancer survivors in Asia may have lower quality of life (QOL) compared with their Western counterparts. However, no studies have made international comparisons in QOL using a comprehensive measure. This study aimed to compare Chinese breast cancer survivors' QOL with US counterparts and examine if demographic and medical factors were associated with QOL across groups.

METHOD

The sample consisted of 159 breast cancer patients (97 Chinese and 62 American) who completed the Functional Assessment for Cancer Therapy Breast Cancer (FACT-B) scale before the start of radiotherapy in Shanghai, China and Houston, USA.

RESULTS

Higher income was associated with higher QOL total scores in both Chinese and American cancer patients, but QOL was not significantly associated with other factors including age, education, disease stage, mastectomy, and chemotherapy. Consistent with hypotheses, compared to their US counterparts, Chinese breast cancer survivors reported lower QOL and all four subdimensions including functional well-being (FWB), physical well-being (PWB), emotional well-being (EWB), and social well-being (SWB); they also reported more breast cancer-specific concerns (BCS). Differences were also clinically significant for Functional Assessment for Cancer Therapy General (FACT-G) scale total scores and the FWB subscale. After controlling for demographic and medical covariates, these differences remained except for the SWB and BCS. Furthermore, Chinese breast cancer survivors receiving chemotherapy reported significantly lower FACT-G scores than those who did not, but this difference did not emerge among US breast cancer survivors.

DISCUSSION

Chinese breast cancer survivors reported poorer QOL on multiple domains compared to US women. Findings indicate that better strategies are needed to help improve the QOL of Chinese breast cancer survivors, especially those who underwent chemotherapy.

Concerns about Breast Cancer, Pain, and Fatigue in Non-Metastatic Breast Cancer Patients Undergoing Primary Treatment

Women diagnosed with breast cancer often endorse psychosocial concerns prior to treatment, which may influence symptom experiences. Among these, low perceived social support relates to elevated fatigue. Those with low social support perceptions may also experience a greater sense of rejection. We sought to determine if social rejection concerns post-surgery predict fatigue interference 12 months later in women with non-metastatic breast cancer. Depressive symptoms and pain severity after completion of adjuvant therapy (six months post-surgery) were examined as potential mediators. Women (N = 240) with non-metastatic breast cancer were recruited 2–10 weeks post-surgery. Multiple regression analyses examined relationships among variables adjusting for relevant covariates. Greater rejection concerns at study entry predicted greater fatigue interference 12 months later (p < 0.01). Pain severity after adjuvant therapy partially mediated the relationship between social rejection concerns and fatigue interference, with significant indirect (β = 0.06, 95% CI (0.009, 0.176)) and direct effects (β = 0.18, SE = 0.07, t(146) = 2.78, p < 0.01, 95% CI (0.053, 0.311)). Therefore, pain levels post-treatment may affect how concerns of social rejection relate to subsequent fatigue interference. Interventions targeting fears of social rejection and interpersonal skills early in treatment may reduce physical symptom burden during treatment and into survivorship.

Cognitive Representation of Treatment-Related Symptoms in Older Adults With Cancer

BACKGROUND

Adults, 65 years or older, are the most common age group diagnosed with cancer. However, little is known about their beliefs (representations) regarding treatment-related symptoms or how they make decisions to manage those symptoms at home.

OBJECTIVE

The aim of this study is to explore symptom representation of treatment-related symptoms in older adults with cancer.

METHODS

A total of 100 older adults in treatment for cancer completed a standardized measure of symptom representation. Demographic and other patient variables were also collected. Analysis of variance, t tests, and Pearson correlations were used for analysis.

RESULTS

Fatigue was both the most common and most noted symptom; however, several most noted symptoms were not common. Overall, older adults believed symptoms were caused by either their cancer or treatment and were unsure if symptoms would last a long time. They were able to recognize symptom consequences but were unsure about their ability to control symptoms. Adults who reported more comorbid illnesses and a higher number of symptoms believed that treatment-related symptoms had higher consequences.

CONCLUSIONS

Findings suggest that older adults experience symptom-related consequences but question the impact that their actions will have on symptom severity. This may contribute to older adult's lack of active symptom self-management.

IMPLICATIONS FOR PRACTICE

Patient education strategies need to address these representations and new interventions may need to be developed to reinforce symptom consequences and empower older adults to self-manage symptoms.

Update on Prevalence of Pain in Patients With Cancer: Systematic Review and Meta-Analysis

CONTEXT

Cancer pain has a severe impact on quality of life and is associated with numerous psychosocial responses. Recent studies suggest that treatment of cancer pain has improved during the last decade.

OBJECTIVES

The aim of this review was to examine the present status of pain prevalence and pain severity in patients with cancer.

METHODS

A systematic search of the literature published between September 2005 and January 2014 was performed using the databases PubMed, Medline, Embase, CINAHL, and Cochrane. Articles in English or Dutch that reported on the prevalence of cancer pain in an adult population were included. Titles and abstracts were screened by two authors independently, after which full texts were evaluated and assessed on methodological quality. Study details and pain characteristics were extracted from the articles with adequate study quality. Prevalence rates were pooled with meta-analysis; meta-regression was performed to explore determinants of pain prevalence.

RESULTS

Of 4117 titles, 122 studies were selected for the meta-analyses on pain (117 studies, n = 63,533) and pain severity (52 studies, n = 32,261). Pain prevalence rates were 39.3% after curative treatment; 55.0% during anticancer treatment; and 66.4% in advanced, metastatic, or terminal disease. Moderate to severe pain (numerical rating scale score ≥5) was reported by 38.0% of all patients.

CONCLUSION

Despite increased attention on assessment and management, pain continues to be a prevalent symptom in patients with cancer. In the upcoming decade, we need to overcome barriers toward effective pain treatment and develop and implement interventions to optimally manage pain in patients with cancer.

[Factors Influencing Quality of Life during Chemotherapy for Colorectal Cancer Patients in South Korea]

PURPOSE

The purpose of this study was to investigate the levels of physical symptoms, anxiety, depression, and quality of life (QOL) during chemotherapy for colorectal cancer patients in South Korea and to identify factors influencing their QOL.

METHODS

Data were collected from 144 colorectal cancer patients receiving chemotherapy during 2012 at one general hospital located in Seoul. Physical symptoms were measured by the M. D. Anderson Symptom Inventory-Gastrointestinal Cancer Module, and anxiety and depression were measured by the Hospital Anxiety Depression Scale. QOL was measured by the Functional Assessment of Cancer Therapy-Colorectal. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, Scheffé post hoc test, Pearson correlation and stepwise multiple regression.

RESULTS

Mean age of the participants was 56.6 and most of them were not employed. In terms of cancer stage, 38.2% were in stage 3, followed by stage 4 (34.7%). The most frequent symptom was lack of appetite, followed by sleep disturbance and fatigue. The mean score for anxiety was 5.40 with a prevalence of 23% and that of depression 8.85 with a prevalence of 64.6%. The mean score for quality of life was 81.93 out of 136 and 75.3% of the variance in QOL was explained by depression, symptoms, anxiety, treatment place, and occupational status. Depression was the strongest predictive factor.

CONCLUSION

Oncology professionals need to pay special attention to relieving depression as well as physical symptoms to improve QOL during chemotherapy for colorectal cancer patients.

Risk factors for depression and fatigue among survivors of hematopoietic cell transplantation

BACKGROUND

Patients treated with hematopoietic cell transplantation (HCT) often experience depression and fatigue but analyses to determine risk factors have typically lacked statistical power. The current study examined sociodemographic and clinical risk factors for depression and fatigue in a large cohort of survivors of HCT.

METHODS

Measures of depression and fatigue were included in an annual survey of HCT recipients that also included self-reported sociodemographic and health information. Patient clinical characteristics were obtained from the clinical database.

RESULTS

The sample consisted of 1869 recipients (with a mean age of 56 years; 53% male) who were a mean of 13 years (allogeneic recipients) and 6 years (autologous recipients) from HCT. Moderate to severe depression was reported by 13% of participants; moderate to severe fatigue was reported by 42%. Among allogeneic recipients, female sex, younger age, current presence of chronic pain, and current patient-reported severity of chronic graft-versus-host disease were found to be independently associated with greater depression whereas female sex, current presence of chronic pain, and current severity of chronic graft-versus-host disease were independently associated with greater fatigue (P values <.01). Among autologous recipients, younger age and current presence of chronic pain were found to be independently associated with both greater depression and greater fatigue (P values <.01).

CONCLUSIONS

Rates of depression and fatigue in this group of survivors suggest a high symptom burden. Better screening, referral, and interventions are needed.

A cross-sectional study of anxiety and marital quality among women with breast cancer at a university clinic in western Saudi Arabia

Objectives:

To examine relationship between the quality of marital relationship and anxiety among women with breast cancer (BC) in the Kingdom of Saudi Arabia (KSA).

Methods:

This cross-sectional study recruited a consecutive series of 49 married women with BC seen in the Al-Amoudi Breast Cancer Center of Excellence at King Abdulaziz University, Jeddah, KSA in early 2013. Participants completed the Hospital Anxiety and Depression Scale, Spouse Perception Scale, and Quality of Marriage Index forms, and answered questions on demographic and cancer characteristics.

Results:

Anxiety symptoms indicating “possible” anxiety disorder were present in 10.4% and “probable” anxiety disorder in 14.6% (25% total). No significant relationship was found between the quality of marital relationship and anxiety symptoms (B=-0.04, standard error=0.05, t=-0.81, p=0.42). Anxiety was primarily driven by low education, poor socioeconomic status, and young age.

Conclusion:

Anxiety symptoms are prevalent among married women with BC seen in a university-based clinic in the KSA. Further research is needed to determine whether a diagnosis of BC adversely affects marital relationship, and whether this is the cause for anxiety in these women.

A nested cohort study of 6,248 early breast cancer patients treated in neoadjuvant and adjuvant chemotherapy trials investigating the prognostic value of chemotherapy-related toxicities

BACKGROUND

The relationship between chemotherapy-related toxicities and prognosis is unclear. Previous studies have examined the association of myelosuppression parameters or neuropathy with survival and reported conflicting results. This study aims to investigate 13 common chemotherapy toxicities and their association with relapse-free survival and breast cancer-specific survival.

METHODS

Chemotherapy-related toxicities were collected prospectively for 6,248 women with early-stage breast cancer from four randomised controlled trials (NEAT; BR9601; tAnGo; Neo-tAnGo). Cox proportional-hazards modelling was used to analyse the association between chemotherapy-related toxicities and both breast cancer-specific survival and relapse-free survival. Models included important prognostic factors and stratified by variables violating the proportional hazards assumption.

RESULTS

Multivariable analysis identified severe neutropenia (grades ≥3) as an independent predictor of relapse-free survival (hazard ratio (HR) = 0.86; 95% confidence interval (CI), 0.76-0.97; P = 0.02). A similar trend was seen for breast cancer-specific survival (HR = 0.87; 95% CI, 0.75-1.01; P = 0.06). Normal/low BMI patients experienced more severe neutropenia (P = 0.008) than patients with higher BMI. Patients with fatigue (grades ≥3) showed a trend towards reduced survival (breast cancer-specific survival: HR = 1.17; 95% CI, 0.99-1.37; P = 0.06). In the NEAT/BR9601 sub-group analysis by treatment component, this effect was statistically significant (HR = 1.61; 95% CI, 1.13-2.30; P = 0.009).

CONCLUSIONS

This large study shows a significant association between chemotherapy-induced neutropenia and increased survival. It also identifies a strong relationship between low/normal BMI and increased incidence of severe neutropenia. It provides evidence to support the development of neutropenia-adapted clinical trials to investigate optimal dose calculation and its impact on clinical outcome. This is important in populations where obesity may lead to sub-optimal chemotherapy doses.

The Use of Complementary and Alternative Medicine by Korean Breast Cancer Women: Is It Associated with Severity of Symptoms?

Background. Use of complementary and alternative medicine (CAM) among patients with breast cancer could be associated with severity of the cancer symptoms experienced, but there is little evidence to prove this. This study tried to investigate any difference in the severity of breast cancer symptoms between CAM users and nonusers. Methods. The study followed cross-sectional design using structured survey questionnaire. Survey participants were recruited from four different healthcare settings in Seoul, South Korea. The survey instrument comprised 39 items including questions on demographics, use of CAM, and six main symptoms associated with breast cancer and cancer treatment. Results. Out of 288 participants, 67% stated using one or more modalities of CAM. Age, education, and time duration since diagnosis of cancer were significantly associated with use of CAM. About 90% of the CAM users experienced side effects of cancer treatment. CAM users reported more severe anxiety and skin/hair changes than nonusers. Conclusions. CAM was used by those breast cancer patients who experience more severe symptoms to alleviate the conditions associated with breast cancer and cancer treatment. Our findings revealed motivation behind the CAM use, which has profound implications for clinicians to recognize patient-perceived needs.

The Effects of Symptoms on Quality of Life during Chemotherapy in African-American Women with Breast Cancer

Little is known about the effects of burdensome symptoms dur- ing chemotherapy treatment in African-American women. This study explored the symptom burden occurring during chemotherapy treatment and how these symptoms impacted functional well-being and quality of life (QOL). A sample of 30 African-American women with breast cancer (BC) completed a battery of questionnaires that were used to collect the data at baseline, midpoint, and at the completion of chemotherapy. There were significant differences in the severity of symptoms for worse pain, pain inteiference with activities of daily living (ADLs), present fatigue and history offatigue, present nausea and history of nausea and insomnia as well as lower intensity of QOL measures over the course of chemotherapy treatment. All symptoms had greater intensity at midpoint and completion than at baseline. Worst pain had a significant negative effect on functional well-being. Both pain and depression each had significant negative effects on QOL.

Depression and quality of life before and after breast cancer diagnosis in older women from the Women's Health Initiative

PURPOSE

Distress and reduced quality of life (QOL) are common among people with cancer. No study has compared these variables after breast cancer diagnosis to pre-cancer diagnosis levels.

METHODS

Data on women with breast cancer 50 years of age or older (n = 6949) were analyzed from the Women's Health Initiative (1993-2013). Health-related QOL (physical function, mental health) was measured using Rand-36. Depressive symptoms were measured with the six-item Center for Epidemiologic Studies Depression scale. Assessments occurred before and after the cancer diagnosis. Hierarchical linear modeling compared pre-cancer QOL and depressive symptoms to levels post-diagnosis and tested whether pre-cancer physical activity, stressful life events, sleep disturbance, and pain predicted post-diagnosis outcomes.

RESULTS

Compared with pre-cancer levels, depressive symptoms increased (20.0% increase at 0-6 months, 12.9% increase at 6-12 months), while physical function (-3.882 points at 0-6 months, -3.545 at 6-12 months) and mental health decreased (-2.899 points at 0-6 months, -1.672 at 6-12 months) in the first year after diagnosis (all p < .01). Depressive symptoms returned to pre-cancer levels after 10 years, but QOL remained significantly lower. At more than 10 years post-diagnosis, physical function was 2.379 points lower than pre-cancer levels (p < 0.01) while mental health was 1.922 points lower (p < 0.01). All pre-cancer predictors were associated with all outcomes. Pain predicted uniquely greater decreases in physical function post-diagnosis.

CONCLUSIONS

Depressive symptoms increased and QOL decreased following breast cancer diagnosis compared with pre-cancer levels, particularly in the first year.

IMPLICATIONS FOR CANCER SURVIVORS

QOL may remain lower for years after breast cancer diagnosis, although decreases are small.
