What are the unmet supportive care needs of people with cancer? A systematic review

Goals of workThe identification and management of unmet supportive care needs is an essential component of health care for people with cancer. Information about the prevalence of unmet need can inform service planning/redesign.Materials and methodsA systematic review of electronic databases was conducted to determine the prevalence of unmet supportive care needs at difference time points of the cancer experience.ResultsOf 94 articles or reports identified, 57 quantified the prevalence of unmet need. Prevalence of unmet need, their trends and predictors were highly variable in all domains at all time points. The most frequently reported unmet needs were those in the activities of daily living domain (1–73%), followed by psychological (12–85%), information (6–93%), psychosocial (1–89%) and physical (7–89%). Needs within the spiritual (14–51%), communication (2–57%) and sexuality (33–63%) domains were least frequently investigated. Unmet needs appear to be highest and most varied during treatment, however a greater number of individuals were likely to express unmet need post-treatment compared to any other time. Tumour-specific unmet needs were difficult to distinguish. Variations in the classification of unmet need, differences in reporting methods and the diverse samples from which patients were drawn inhibit comparisons of studies.ConclusionThe diversity of methods used in studies hinders analysis of patterns and predictors of unmet need among people with cancer and precludes generalisation. Well-designed, context-specific, prospective studies, using validated instruments and standard methods of analysis and reporting, are needed to benefit future interventional research to identify how best to address the unmet supportive care needs of people with cancer.

Mindfulness-based cognitive therapy for individuals whose lives have been affected by cancer: A randomized controlled trial.

OBJECTIVE This study evaluated the effectiveness of mindfulness-based cognitive therapy (MBCT) for individuals with a diagnosis of cancer. METHOD Participants (N = 115) diagnosed with cancer, across site and stage, were randomly allocated to either the treatment or the wait-list condition. Treatment was conducted at 1 site, by a single therapist, and involved participation in 8 weekly 2-hr sessions that focused on mindfulness. Participants meditated for up to 1 hr daily and attended an additional full-day session during the course. Participants were assessed before treatment and 10 weeks later; this second assessment occurred immediately after completion of the program for the treatment condition. The treatment condition was also assessed at 3 months postintervention. All postinitial assessments were completed by assessors who were blind to treatment allocation. RESULTS There were large and significant improvements in mindfulness (effect size [ES] = 0.55), depression (ES = 0.83), anxiety (ES = 0.59), and distress (ES = 0.53) as well as a trend for quality of life (ES = 0.30) for MBCT participants compared to those who had not received the training. The wait-list group was assessed before and after receiving the intervention and demonstrated similar change. CONCLUSIONS These improvements represent clinically meaningful change and provide evidence for the provision of MBCT within oncology settings.

Epidemiological evidence for a relationship between life events, coping style, and personality factors in the development of breast cancer

OBJECTIVE Review empirical evidence for a relationship between psychosocial factors and breast cancer development. METHODS Standardised quality assessment criteria were utilised to assess the evidence of psychosocial predictors of breast cancer development in the following domains: (a) stressful life events, (b) coping style, (c) social support, and (d) emotional and personality factors. RESULTS Few well-designed studies report any association between life events and breast cancer, the exception being two small studies using the Life Events and Difficulties Schedule (LEDS) reporting an association between severely threatening events and breast cancer risk. Seven studies show anger repression or alexithymia are predictors, the strongest evidence suggesting younger women are at increased risk. There is no evidence that social support, chronic anxiety, or depression affects breast cancer development. With the exception of rationality/anti-emotionality, personality factors do not predict breast cancer risk. CONCLUSION The evidence for a relationship between psychosocial factors and breast cancer is weak. The strongest predictors are emotional repression and severe life events. Future research would benefit from theoretical grounding and greater methodological rigour. Recommendations are given.

A review and recommendations for optimal outcome measures of anxiety, depression and general distress in studies evaluating psychosocial interventions for English-speaking adults with heterogeneous cancer diagnoses.

ObjectiveThe objective of this paper is to inform choice of optimal patient-reported outcome measures (PROMs) of anxiety, depression and general distress for studies evaluating psychosocial interventions for English-speaking adults with heterogenous cancer diagnoses.MethodsA systematic review was conducted to identify all PROMs used to assess anxiety, depression and general distress in randomised controlled trials (RCTs) of psychosocial interventions for people with cancer published between 1999 and May 2009. Candidate PROMs were evaluated for content, evidence of reliability and validity, clinical meaningfulness, comparison data, efficiency, ease of administration, cognitive burden and track record in identifying treatment effects in RCTs of psychosocial interventions. Property ratings were weighted and summed to give an overall score out of 100.ResultsThe Hospital Anxiety and Depression Scale (HADS) scored highest overall (weighted score = 77.5), followed by the unofficial short-form of the Profile of Mood States (POMS), the POMS-37 (weighted score = 60), and the Centre for Epidemiological Studies Depression Scale (CES-D) and original POMS (weighted score = 55 each).ConclusionsThe HADS’ efficiency and substantial track record recommend its use where anxiety, mixed affective disorders or general distress are outcomes of interest. However, continuing controversy concerning the HADS depression scale cautions against dependence where depressive disorders are of primary interest. Where cost is a concern, the POMS-37 is recommended to measure anxiety or mixed affective disorders but does not offer a suitable index of general distress and, like the HADS, emphasises anhedonia in measuring depression. Where depression is the sole focus, the CES-D is recommended.

Choosing between the EORTC QLQ-C30 and FACT-G for measuring health-related quality of life in cancer clinical research: issues, evidence and recommendations

BACKGROUND This review aims to assist cancer clinical researchers in choosing between the two most widely used measures of cancer-specific health-related quality of life: the European Organisation for the Research and Treatment of Cancer Quality of Life Questionnaire Core 30 and Functional Assessment of Cancer Therapy-General (FACT-G). MATERIALS AND METHODS Information on QLQ-C30 and FACT-G content, scale structure, accessibility and availability was collated from websites and manuals. A systematic review was undertaken to identify all articles reporting on psychometric properties and information to assist interpretability. Evidence for reliability, validity and responsiveness was rated using a standardised checklist. Instrument properties were compared and contrasted to inform recommendations. RESULTS Psychometric evidence does not recommend one questionnaire over the other in general. However, there are important differences between the scale structure, social domains and tone that inform choice for any particular study. CONCLUSIONS Where research objectives are concerned with the impact of a specific tumour type, treatment or symptom, choice should be guided by the availability, content, scale structure and psychometric properties of relevant European Organisation for the Research and Treatment of Cancer versus Functional Assessment of Chronic Illness Therapy modules. Because the FACT-G combines symptoms and concerns within each scale, individual items should always be reviewed within the context of specific research objectives. Where these issues are indecisive, researchers are encouraged to use an algorithm at the end of the current article.

Psychosocial interventions and quality of life in gynaecological cancer patients: A systematic review

Objective: Women with gynaecological cancer are at risk of poor quality of life outcomes. Although various psychosocial interventions have been developed to address these concerns, such interventions have not yet been systematically evaluated in this population. The current review provides an up‐to‐date and comprehensive summary of the evidence regarding the effectiveness of psychosocial interventions in women with gynaecological cancers.

The authors conducted the current study to determine whether personality predisposes some individuals to develop cancer.

Short- and Long-Term Impact of Receiving Genetic Mutation Results in Women at Increased Risk for Hereditary Breast Cancer

Forty-seven unaffected women from high-risk breast cancer families who had received results for hereditary breast/ovarian predisposition genes between 1 month and 5 years ago were interviewed regarding their experiences. Women responded to open-ended questions. The initial emotional turmoil reported by most was generally short lived. However, the impact of genetic testing went beyond the individual to the extended family and social context, particularly in the short-term. A common theme was the difficulty associated with divulging a result to family members, who were also adjusting to their own result. The majority of carriers reported advantages that were both physical (options for surveillance programs and prophylactic surgery) and emotional (reduced uncertainty, increased awareness of options and knowledge about risk, preparation time). Most carriers reported no change in lifestyle although some reported discovering their mutation status as a positive life-changing experience. Implications for genetic counseling and further research are discussed.

Prevalence and Predictors of Sleep Difficulty in a National Cohort of Women with Primary Breast Cancer Three to Four Months Postsurgery

CONTEXT Mounting evidence suggests that many cancer patients suffer from sleep difficulty, but there is conflicting evidence regarding the prevalence and predictors of this adverse symptom. OBJECTIVES The present study investigated the prevalence and predictors of clinically significant sleep difficulty in women with primary breast cancer. METHODS Danish women (n=3343) with primary breast cancer completed the Pittsburgh Sleep Quality Index (PSQI) along with measures of depression, anxiety, physical activity/functioning, and health behaviors three to four months postsurgery. Data on disease status, treatment, and comorbidity were obtained from the Danish Cancer Cooperative Group and surgical departments, and information on sociodemographic factors and psychiatric history was obtained from Danish national longitudinal registries. RESULTS More than half (57.9%) of the women reported clinically significant sleep difficulty (PSQI >5). Multiple logistic regression identified seven significant predictors of sleep difficulty in the full sample. In order of strength, these were the following: more depressive symptoms, poorer physical functioning, older age, higher levels of trait anxiety, consuming more cigarettes, having undergone lumpectomy, and lower levels of physical activity. Subgroup analysis found that more depressive symptoms and poorer physical functioning were the only two predictors that were significant in both pre- and postmenopausal women. CONCLUSION These findings indicate that a high proportion of women with breast cancer experience sleep difficulty. Depression and poorer physical functioning appear to be robust predictors of sleep difficulty, whereas other predictors may depend on sample characteristics, including menopausal status.

Attitudes to Prophylactic Surgery and Chemoprevention in Australian Women at Increased Risk for Breast Cancer

BACKGROUND Because of the uncertain efficacy of breast cancer screening in women at increased risk of developing breast cancer, bilateral prophylactic oophorectomy and mastectomy are considered management options for high-risk women. Data on the attitudes to prophylactic strategies of high-risk women who have not attended specialist clinics are needed to ascertain the need for patient education and provide the basis for planning of support services. METHODS Three hundred seventy-one women unaffected by cancer and with unknown mutation status from families with a dominantly inherited susceptibility to breast cancer, recruited through a large Australian population-based, epidemiological study, were assessed using a mailed self-administered questionnaire with validated measures of psychological outcome. RESULTS Sixteen percent of women reported considering prophylactic mastectomy, and 1% had already had the procedure. Among women with a family history of breast/ovarian cancer, 33% had considered and 5% had already had a prophylactic oophorectomy. Twenty-three percent of women reported considering taking tamoxifen if it were shown to prevent breast cancer. Consideration of prophylactic oophorectomy (OR = 1.51 for a 10% change in perceived risk, 95% CI 1.14-1.99, p = 0.0045) and tamoxifen (OR = 1.14 for a 10% change in perceived risk, 95% CI 1.002-1.30, p = 0.047) were positively associated with perceived cancer risk. CONCLUSIONS Attitudes to prophylactic surgery and psychological distress levels in high-risk women participating in an epidemiological study appear to be comparable to those of women attending familial cancer clinics and indicate that women attending high-risk clinics may be representative of the larger population of women at increased risk.
