Psychological interventions for women with metastatic breast cancer

Cancer patients' experiences of moments of relational depth during psychological therapy: a qualitative study

OBJECTIVE

Research into psychological interventions for cancer patients has focused on the effectiveness of different treatment methods. Investigating common factors across treatments, such as qualities within the therapeutic relationship, has been neglected. This study explores cancer patients' experiences of moments of profound contact and engagement with their therapist, including any perceived impact.

METHODS

Semi-structured interviews were conducted with ten cancer patients. Eight participants reported having experienced moments of relational depth. Their transcripts were analyzed using thematic analysis.

FINDINGS

Five themes were identified: "Being physically and psychically vulnerable," "Being rescued from the waves," "Experiencing the calm after the storm," "More than a feeling," and "The therapist as 'a stranger and not a stranger'."

CONCLUSION

Both novice and experienced practitioners should be aware of the potential power of moments of relational depth for cancer patients: to normalize patients' increased vulnerability and emotionality, and to manage breaks and endings with relational sensitivity.

Effect of a mentor-based, supportive-expressive program, Be Resilient to Breast Cancer, on survival in metastatic breast cancer: a randomised, controlled intervention trial

BACKGROUND

Because of medical advances, metastatic breast cancer (MBC) is now viewed as a chronic disease, rather than an imminent death sentence. Helping women live with this disease requires more than a medical approach to symptoms. Thus, a mentor-based and supportive-expressive program 'Be Resilient to Breast Cancer' (BRBC) was designed to help Chinese women with MBC enhance their resilience levels, biopsychosocial functions, and potentially extend their life span.

METHODS

A total of 226 women with MBC were randomly assigned, in a 1 : 1 ratio, to an intervention group (IG) that participated in BRBC or to a control group (CG) that received no intervention. Be Resilient to Breast Cancer was conducted for 120 min once a week. Primary outcomes were cancer-specific survival and secondary outcomes were resilience, Allostatic Load Index (ALI), anxiety, depression, and quality of life (QoL). The Cox proportional-hazards model was used for survival analysis and growth mixture models were performed for secondary outcomes.

RESULTS

Be Resilient to Breast Cancer did not significantly prolong 3- or 5-year survival (median survival, 36.7 months in IG and 31.5 months in CG). The hazard ratio for death was 0.736 (95% CI, 0.525-1.133, P=0.076; univariate Cox model) and 0.837 (95% CI, 0.578-1.211, P=0.345; multivariate Cox analysis). The IG improved in anxiety (ES=0.85, P<0.001), depression (ES=0.95, P<0.001), QoL (ES=0.55, P<0.001), resilience (ES=0.67, P<0.001), and ALI (ES=0.90, P<0.001) compared to CG.

CONCLUSIONS

BRBC does not improve survival of women with MBC in this study, though longer follow up is warranted. It positively impacts resilience, QoL, ALI, and emotional distress.

A cognitive-existential intervention to improve existential and global quality of life in cancer patients: A pilot study

OBJECTIVE

We developed a specific cognitive-existential intervention to improve existential distress in nonmetastatic cancer patients. The present study reports the feasibility of implementing and evaluating this intervention, which involved 12 weekly sessions in both individual and group formats, and explores the efficacy of the intervention on existential and global quality of life (QoL) measures.

METHOD

Some 33 nonmetastatic cancer patients were randomized between the group intervention, the individual intervention, and the usual condition of care. Evaluation of the intervention on the existential and global QoL of patients was performed using the existential well-being subscale and the global scale of the McGill Quality of Life (MQoL) Questionnaire.

RESULTS

All participants agreed that their participation in the program helped them deal with their illness and their personal life. Some 88.9% of participants agreed that this program should be proposed for all cancer patients, and 94.5% agreed that this intervention helped them to reflect on the meaning of their life. At post-intervention, both existential and psychological QoL improved in the group intervention versus usual care (p = 0.086 and 0.077, respectively). At the three-month follow-up, global and psychological QoL improved in the individual intervention versus usual care (p = 0.056 and 0.047, respectively).

SIGNIFICANCE OF RESULTS

This pilot study confirms the relevance of the intervention and the feasibility of the recruitment and randomization processes. The data strongly suggest a potential efficacy of the intervention for existential and global quality of life, which will have to be confirmed in a larger study.

Complementary and alternative medicine for cancer pain: an overview of systematic reviews

Background and Objective. Now with more and more published systematic reviews of Complementary and Alternative Medicine (CAM) on adult cancer pain, it is necessary to use the methods of overview of systematic review to summarize available evidence, appraise the evidence level, and give suggestions to future research and practice. Methods. A comprehensive search (the Cochrane Library, PubMed, Embase, and ISI Web of Knowledge) was conducted to identify all systematic reviews or meta-analyses of CAM on adult cancer pain. And the evidence levels were evaluated using GRADE approach. Results. 27 systematic reviews were included. Based on available evidence, we could find that psychoeducational interventions, music interventions, acupuncture plus drug therapy, Chinese herbal medicine plus cancer therapy, compound kushen injection, reflexology, lycopene, TENS, qigong, cupping, cannabis, Reiki, homeopathy (Traumeel), and creative arts therapies might have beneficial effects on adult cancer pain. No benefits were found for acupuncture (versus drug therapy or shame acupuncture), and the results were inconsistent for massage therapy, transcutaneous electric nerve stimulation (TENS), and Viscum album L plus cancer treatment. However, the evidence levels for these interventions were low or moderate due to high risk of bias and/or small sample size of primary studies. Conclusion. CAM may be beneficial for alleviating cancer pain, but the evidence levels were found to be low or moderate. Future large and rigor randomized controlled studies are needed to confirm the benefits of CAM on adult cancer pain.

Psychological interventions for women with metastatic breast cancer

BACKGROUND

Psychological symptoms are associated with metastatic breast cancer. This is the basis for exploring the impact of psychological interventions on psychosocial and survival outcomes. One early study appeared to show significant survival and psychological benefits from psychological support while subsequent studies have revealed conflicting results. This review is an update of a Cochrane review first published in 2004 and previously updated in 2007.

OBJECTIVES

To assess the effects of psychological interventions on psychosocial and survival outcomes for women with metastatic breast cancer.

SEARCH METHODS

We searched the Cochrane Breast Cancer Group Specialised Register, MEDLINE (OvidSP), EMBASE (OvidSP), PsycINFO (OvidSP), CINAHL (EBSCO), online trials and research registers in June/July 2011. Further potentially relevant studies were identified from handsearching references of previous trials, systematic reviews and meta-analyses. 

SELECTION CRITERIA

Randomised controlled trials (RCTs) and cluster RCTs of psychological interventions, which recruited women with metastatic breast cancer. Outcomes selected for analyses were overall survival, psychological outcomes, pain, quality of life, condition-specific outcome measures, relationship and social support measures, and sleep quality. Studies were excluded if no discrete data were available on women with metastatic breast cancer. 

DATA COLLECTION AND ANALYSIS

Two review authors independently extracted the data and assessed the quality of the studies using the Cochrane Collaboration risk of bias tool. Where possible, authors were contacted for missing information. Data on the nature and setting of the intervention, relevant outcome data, and items relating to methodological quality were extracted. Meta-analyses was performed using a random-effects or fixed-effect Mantel-Haenszel model, depending on expected levels of heterogeneity.

MAIN RESULTS

Ten RCTs with 1378 women were identified. Of the seven RCTs on group psychological interventions, three were on cognitive behavioural therapy and four were on supportive-expressive group therapy. The remaining three studies were individual based and the types of psychological interventions were not common to either cognitive behavioural or supportive-expressive therapy. A clear pattern of psychological outcomes could not be discerned as a wide variety of outcome measures and durations of follow-up were used in the included studies. The overall effect of the psychological interventions across six studies, on one-year survival, favoured the psychological intervention group with an odds ratio (OR) of 1.46 (95% confidence interval (CI) 1.07 to 1.99). Pooled data from four studies did not show any survival benefit at five-years follow-up (OR 1.03, 95% CI 0.42 to 2.52). There was evidence of a short-term benefit for some psychological outcomes and improvement in pain scores.

AUTHORS' CONCLUSIONS

Psychological interventions appear to be effective in improving survival at 12 months but not at longer-term follow-up, and they are effective in reducing psychological symptoms only in some of the outcomes assessed in women with metastatic breast cancer. However, findings of the review should be interpreted with caution as there is a relative lack of data in this field, and the included trials had reporting or methodological weaknesses and were heterogeneous in terms of interventions and outcome measures.  

Psychosocial interventions to improve quality of life and emotional wellbeing for recently diagnosed cancer patients

BACKGROUND

A cancer diagnosis may lead to significant psychological distress in up to 75% of cases. There is a lack of clarity about the most effective ways to address this psychological distress.

OBJECTIVES

To assess the effects of psychosocial interventions to improve quality of life (QoL) and general psychological distress in the 12-month phase following an initial cancer diagnosis.

SEARCH METHODS

We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library 2010, Issue 4), MEDLINE, EMBASE, and PsycINFO up to January 2011. We also searched registers of clinical trials, abstracts of scientific meetings and reference lists of included studies. Electronic searches were carried out across all primary sources of peer-reviewed publications using detailed criteria. No language restrictions were imposed.

SELECTION CRITERIA

Randomised controlled trials of psychosocial interventions involving interpersonal dialogue between a 'trained helper' and individual newly diagnosed cancer patients were selected. Only trials measuring QoL and general psychological distress were included. Trials involving a combination of pharmacological therapy and interpersonal dialogue were excluded, as were trials involving couples, family members or group formats.

DATA COLLECTION AND ANALYSIS

Trial data were examined and selected by two authors in pairs with mediation from a third author where required. Where possible, outcome data were extracted for combining in a meta-analyses. Continuous outcomes were compared using standardised mean differences and 95% confidence intervals, using a random-effects model. The primary outcome, QoL, was examined in subgroups by outcome measurement, cancer site, theoretical basis for intervention, mode of delivery and discipline of trained helper. The secondary outcome, general psychological distress (including anxiety and depression), was examined according to specified outcome measures.

MAIN RESULTS

A total of 3309 records were identified, examined and the trials subjected to selection criteria; 30 trials were included in the review. No significant effects were observed for QoL at 6-month follow up (in 9 studies, SMD 0.11; 95% CI -0.00 to 0.22); however, a small improvement in QoL was observed when QoL was measured using cancer-specific measures (in 6 studies, SMD 0.16; 95% CI 0.02 to 0.30). General psychological distress as assessed by 'mood measures' improved also (in 8 studies, SMD - 0.81; 95% CI -1.44 to - 0.18), but no significant effect was observed when measures of depression or anxiety were used to assess distress (in 6 studies, depression SMD 0.12; 95% CI -0.07 to 0.31; in 4 studies, anxiety SMD 0.05; 95% CI -0.13 to 0.22). Psychoeducational and nurse-delivered interventions that were administered face to face and by telephone with breast cancer patients produced small positive significant effects on QoL (in 2 studies, SMD 0.23; 95% CI 0.04 to 0.43).

AUTHORS' CONCLUSIONS

The significant variation that was observed across participants, mode of delivery, discipline of 'trained helper' and intervention content makes it difficult to arrive at a firm conclusion regarding the effectiveness of psychosocial interventions for cancer patients. It can be tentatively concluded that nurse-delivered interventions comprising information combined with supportive attention may have a beneficial impact on mood in an undifferentiated population of newly diagnosed cancer patients.

Impact of cancer on everyday life: a systematic appraisal of the research evidence

OBJECTIVE

To conduct a systematic appraisal of the published literature reviews related to the impact of cancer on everyday life. This theme was identified as the top priority area for research by participants in the Macmillan Listening Study, which was the first UK-wide public consultation exercise to identify patients' priorities for cancer research.

SEARCH STRATEGY

The top priority area was divided into ten sub-themes, and a modified systematic review was undertaken for each sub-theme using electronic searches.

INCLUSION CRITERIA

Literature review papers were included if they were written in English, involved patients diagnosed ≥18 years, any cancer types and published between 2000 and 2006.

DATA EXTRACTION AND SYNTHESIS

Two thousand and two hundred and fifty-two potentially eligible papers were identified. Abstracts were read by the first author and selected for inclusion in the review. Twenty percentages of the papers were also read independently by other authors. Sixty-two review papers were finally selected.

MAIN RESULTS

The systematic appraisal revealed that some sub-themes of the patient-identified priority area (e.g., how to support family members of cancer patients) were under-researched, while other sub-themes (e.g., anxiety and depression experienced by cancer patients) had been explored to some extent. Certain areas of research interest to patients were found to have been explored; however, their significance was limited by the quality of the research.

CONCLUSION

The systematic appraisal highlights important areas for future research and the need for more effective dissemination of study findings to wider audiences, including service users. This study also indicates the need for further research to enhance the generalizability and/or significance of findings.

Qualitative exploration of healthcare relationships following delayed diagnosis of ovarian cancer and subsequent participation in supportive-expressive group therapy

PURPOSE/OBJECTIVES

To explore the role of supportive-expressive group therapy (SEGT) in facilitating the development and quality of healthcare relationships in patients with ovarian cancer.

RESEARCH APPROACH

Qualitative, grounded theory, and comparative approach.

SETTING

Tertiary care cancer center.

SAMPLE

6 patients with advanced ovarian cancer and 3 healthcare professionals.

METHODOLOGIC APPROACH

Patients participated in semistructured interviews that examined the nature of their healthcare relationships, diagnoses, and SEGT experience. The primary gynecologic oncologist and two nurses responsible for the care of the patients also were interviewed. Analysis of this qualitative study employed a grounded theory technique.

MAIN RESEARCH VARIABLES

Patients' and healthcare professionals' perceptions of healthcare relationships.

FINDINGS

Patients' negative diagnostic experiences were found to influence the quality of relationships with healthcare providers. However, the process appears to benefit from patient participation in SEGT. Patients perceived that SEGT helped facilitate communication between patients and professionals. Patients also indicated that SEGT led them to participate more actively in the treatment process. Professionals viewed patient participation in SEGT as a positive outlet for emotional expression, a source of psychological healing, and a tool that facilitated communication, collaboration, and understanding of medical treatment.

CONCLUSIONS

Participation in SEGT can advance communication and collaboration in medical care and provide opportunity and resources for psychological healing.

INTERPRETATION

SEGT provides a vehicle to enhance the quality of life of patients with ovarian cancer by breaking down the common feeling of isolation, addressing women's frustration and resentment regarding delayed diagnosis, and enhancing relationships with healthcare providers to promote collaborative care in this patient population.

Effects of exercise intervention on persons with metastatic cancer: a systematic review

PURPOSE

To systematically review and synthesize results of studies that examined the effects of exercise on persons with metastatic cancer.

METHODS

Databases searched were MEDLINE, EMBASE, CINAHL, PsycINFO, and Cochrane Central Register of Controlled Trials. Search terms used were "metastatic or advanced or palliative AND cancer or neoplasms AND exercise or physical activity or exercise therapy or physical fitness." The search identified 8 studies published in 10 articles between 2000 and 2007. Two quality-assessment tools were used, and levels of evidence were assigned according to the Oxford Centre for Evidence-Based Medicine (CEBM) guidelines.

RESULTS

Of the eight studies, three were randomized controlled trials (RCTs) and five were case series. Because three of the RCTs were based on the same sample, only one was included in the results and discussion sections. CEBM levels of evidence ranged from 2b to 4. Two overall recommendations were made, one grade A and one grade C. Exercise interventions ranged from aerobic exercise and strength training to multidimensional programmes with exercise as one component. All studies used physical and/or quality-of-life outcome measures.

CONCLUSIONS

Review findings suggest that exercise may be beneficial for persons with metastatic cancer. Future research should clarify optimal exercise dose parameters.

Psychosocial interventions for reducing fatigue during cancer treatment in adults

BACKGROUND

Fatigue is a common symptom in cancer patients receiving active treatment. There are a limited number of reviews evaluating interventions for fatigue during active treatment, and they are restricted to patients with advanced cancer, or to patients during radiotherapy. To date there is no systematic review on psychosocial interventions for fatigue during cancer treatment.

OBJECTIVES

To evaluate if psychosocial interventions are effective in reducing fatigue in cancer patients receiving active treatment for cancer, and which types of psychosocial interventions are the most effective.

SEARCH STRATEGY

In September 2008 we searched the Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), PUBMED, MEDLINE, EMBASE, CINAHL and PsycINFO, and checked the reference lists.

SELECTION CRITERIA

Randomised controlled trials (RCTs) were included which evaluated psychosocial interventions in adult cancer patients during treatment, with fatigue as an outcome measure.

DATA COLLECTION AND ANALYSIS

Three review authors independently extracted data from the selected studies, and assessed the methodological quality using several quality rating scales and additional criteria.

MAIN RESULTS

Twenty-seven studies met the inclusion criteria with a total of 3324 participants, and seven studies reported significant effects of the psychosocial intervention on fatigue. In three studies the effect was maintained at follow-up. The quality of the studies was generally moderate. Effect sizes varied between 0.17 to 1.07.The effectiveness of interventions specific for fatigue was significantly higher (80%) compared to interventions not specific for fatigue (14%). In five studies the interventions were specifically focused on fatigue, with four being effective. The five interventions were brief, consisting of three individual sessions, provided by (oncology) nurses. In general, during these interventions participants were educated about fatigue, were taught in self-care or coping techniques, and learned activity management.Of the remaining 22 studies only three were effective in reducing fatigue, and these interventions had a more general approach. These interventions were aimed at psychological distress, mood and physical symptoms, and varied strongly in duration and content.

AUTHORS' CONCLUSIONS

There is limited evidence that psychosocial interventions during cancer treatment are effective in reducing fatigue. At present, psychosocial interventions specifically for fatigue are a promising type of intervention. However, there is no solid evidence for the effectiveness of interventions not specific for fatigue. Most aspects of the included studies were heterogeneous, and therefore it could not be established which other types of interventions, or elements were essential in reducing fatigue.

Psychological interventions for women with metastatic breast cancer

BACKGROUND

Systematic reviews of psychological interventions for patients with cancer are conflicting, some showing benefits for patients and others not. One early study appeared to show significant survival and psychological benefits from a psychological intervention given to women with metastatic breast cancer. Subsequent studies have however demonstrated conflicting results.

OBJECTIVES

To assess the effects of psychological interventions (educational, individual cognitive behavioural or psychotherapeutic, or group support) on psychological and survival outcomes for women with metastatic breast cancer.

SEARCH STRATEGY

For this update, the Cochrane Breast Cancer Group Specialised Register was searched (September 2007). Also searched were MEDLINE (1966-September 2006), CINAHL (1982-September 2006), PsycInfo (1974-September 2006), and SIGLE (1980-September 2006).

SELECTION CRITERIA

Randomised controlled trials (RCTs) of psychological interventions for women with metastatic breast cancer. Studies which were not t 'intention to treat' were included owing to the nature of the patient group under study and the likely high loss of follow-up data.

DATA COLLECTION AND ANALYSIS

Data were extracted independently by two reviewers. Data about the nature and setting of the intervention, relevant outcome data and items relating to methodological quality were extracted.

MAIN RESULTS

Five primary studies (511 women) were identified all group psychological interventions. Two of these were cognitive behavioural interventions and three evaluated support-expressive group therapy. The five studies of group psychological therapies showed very limited evidence of benefit arising from these interventions. Although there was evidence of short-term benefit for some psychological outcomes, in general these were not sustained at follow-up. A clearer pattern of psychological outcomes could not be discerned as a wide variety of outcome measures and durations of follow-up were used in the included studies. The possible longer survival times in women allocated to receive psychological intervention in the early study have not been replicated in the subsequent four studies (including one by members of the first study group), and overall the effects of these interventions on survival are not statistically significant (for example, odds ratio for 5 year survival 0.83 (95% confidence interval [CI] 0.53 - 1.28).

AUTHORS' CONCLUSIONS

There is insufficient evidence to advocate that group psychological therapies (either cognitive behavioural or supportive-expressive) should be made available to all women diagnosed with metastatic breast cancer. Any benefits of the interventions are only evident for some of the psychological outcomes and in the short term. The possibility of the interventions causing harm is not ruled out by the available data.

Unmet needs in cancer patients: development of a supportive needs screening tool (SNST)

GOALS OF WORK

A diagnosis of cancer can have a profound impact on the physical, emotional, psychological, social and spiritual areas of a person's life. Supportive care services are directed towards this full range of issues associated with cancer. Identification of need is the first step in meeting supportive care concerns, but there is a lack of tools and processes regularly used in clinical practice. This article reports the first steps in the development of a supportive needs screening tool appropriate for use in an oncology outpatient setting.

MATERIALS AND METHODS

A review of the literature was undertaken, and a draft tool developed using a process of item reduction. A small pre-test followed by a pilot test with 87 patients attending Peter MacCallum Cancer Centre, Melbourne Australia was undertaken. Evaluation to identify usability and acceptability in clinical practice included descriptive statistics to profile patient needs and referrals generated by the supportive needs screening tool (SNST), interviews with a small sample of participants and surveys completed by staff.

MAIN RESULTS

The SNST was developed with 41 questions, the majority requiring a yes/no response. From the tool, a total of 1,085 needs were identified (mean = 12 needs/patient). A total of 264 referrals were generated, with 72% of patients receiving at least one referral. Patients and staff reported high acceptability.

CONCLUSIONS

The SNST has face validity and demonstrated usability in an ambulatory care oncology stetting, as first steps in instrument development. Further testing of reliability and validity are being undertaken.

Yoga for women with metastatic breast cancer: results from a pilot study

Metastatic breast cancer (MBC) remains a terminal illness for which major treatment advances are slow to appear, and hence it is crucial that effective palliative interventions be developed to reduce the cancer-related symptoms of women with this condition during the remaining years of their lives. This pilot/feasibility study examined a novel, yoga-based palliative intervention, the Yoga of Awareness Program, in a sample of women with MBC. The eight-week protocol included gentle yoga postures, breathing exercises, meditation, didactic presentations, and group interchange. Outcome was assessed using daily measures of pain, fatigue, distress, invigoration, acceptance, and relaxation during two preintervention weeks and the final two weeks of the intervention. Thirteen women completed the intervention (mean age=59; mean time since diagnosis=7 years; two African American, 11 Caucasian). During the study, four participants had cancer recurrences, and the physical condition of several others deteriorated noticeably. Despite low statistical power, pre-to-post multilevel outcomes analyses showed significant increases in invigoration and acceptance. Lagged analyses of length of home yoga practice (controlling for individual mean practice time and outcome levels on the lagged days) showed that on the day after a day during which women practiced more, they experienced significantly lower levels of pain and fatigue, and higher levels of invigoration, acceptance, and relaxation. These findings support the need for further investigation of the effects of the Yoga of Awareness Program in women with MBC.

Meeting the support and information needs of women with advanced breast cancer: a randomised controlled trial

Addressing psychosocial and quality of life needs is central to provision of excellent care for people with advanced cancer. This study tested a brief nurse-delivered intervention to address the needs of urban women with advanced breast cancer. This study was conducted at four large urban hospitals in Australia. One hundred and five women with advanced breast cancer were recruited and randomised to receive the intervention or usual care, then asked to complete the European Organisation of Research and Treatment of Quality of life Q-C30 version (2.0) (EORTC Q-C30) (version 2) and Supportive Care Needs Survey (SCNS) at 1 month and 3 months postrecruitment. No significant differences were detected between intervention and usual care groups in the SCNS or the EORTC Q-C30 subscale scores. However, when the groups were divided into high needs (score of above 50) and low baseline needs (score of 50 or below) for each SCNS subscale, a significant difference between intervention and usual care groups was found in the psychological/emotional subscale among women with high baseline needs. In conclusions, this study demonstrated that a face-to-face session and follow-up phone call with a breast care nurse significantly reduced the psychological and emotional needs of those with high initial needs. There was no evidence of the intervention influencing the quality of life; or perceived needs of women with low initial psychological/emotional needs or perceived needs in other domains. Possibly, the intervention was not sufficiently intense to achieve an effect.

Reduction in uptake of PSA tests following decision aids: systematic review of current aids and their evaluations

A man's decision to have a prostate-specific antigen (PSA) test should be an informed one. We undertook a systematic review to identify and appraise PSA decision aids and evaluations. We searched 15 electronic databases and hand-searched key journals. We also contacted key authors and organisations. All decision aids and evaluations that discussed PSA were included, with meta-analyses performed on two outcomes from the evaluations: PSA testing and patient knowledge of PSA and related issues. Seven decision aids and 11 evaluations were included. The meta-analysis showed a significantly reduced probability in PSA testing after a decision aid: -3.5% (95% confidence interval: 0.0 to 7.2%; P = 0.050). There were significant improvements in knowledge within 2 weeks after a decision aid: 19.5% (95% confidence interval: 14.2 to 24.8%; P < 0.001). The effect on knowledge was less pronounced within 12-18 months after a decision aid: 3.4% (95% confidence interval: -0.7 to 7.4%; P = 0.10). PSA decision aids improve knowledge about PSA testing, at least in the short term. Men given these decision aids seem to be less likely to have the PSA test.

Psychiatric disorders following first breast cancer recurrence: prevalence, associated factors and relationship to quality of life

OBJECTIVE

The purpose of this study was to investigate the prevalence of and factors associated with psychiatric disorders and the impact on quality of life (QOL) in patients with first breast cancer recurrence.

METHODS

We analyzed the baseline data on 50 consecutively enrolled recurrent breast cancer patients, participating in a feasibility study of multifaceted psychosocial intervention. Psychiatric disorders, including major depressive disorder (MDD), dysthymic disorder, panic disorder, post-traumatic stress disorder (PTSD), generalized anxiety disorder and adjustment disorders (AD), were evaluated according to the Structured Clinical Interview for the DSM-III-R and IV. The patients' demographic data, biomedical factors, social support, mental adjustment to cancer, personality traits and QOL were also evaluated.

RESULTS

Eleven (22%) met the DSM-III-R and IV criteria for MDD, PTSD or AD (MDD, 2%; PTSD, 2%; AD, 20%). Univariate analysis indicated that current doxorubicin/cyclophosphamide, presence of a confidant, past history of MDD, helplessness/hopelessness and neuroticism were significantly associated with psychiatric disorders. On multivariate logistic regression analysis, past history of MDD and helplessness/hopelessness were significant associated factors. Psychiatric disorders were significantly associated with lower functional scales ('emotional functioning', 'body image' and 'future perspective') and higher symptom scales ('appetite loss', 'diarrhea', 'fatigue' and 'nausea-vomiting') in QOL.

CONCLUSIONS

The result suggests that asking about history of depression and appropriate intervention, including psycho-education, are needed for patients with first breast cancer recurrence in order to detect and manage psychological distress. Although further studies are needed to clarify causal links between psychiatric disorders and QOL, patients' psychiatric disorders were associated with QOL.

Psychological interventions for women with metastatic breast cancer

BACKGROUND

There have been conflicting results from systematic reviews of psychological interventions for patients with cancer, some showing benefits for patients and others not. One early study appeared to show significant survival benefits as well as psychological benefits from a psychological intervention given to women with metastatic breast cancer. Some further studies have been undertaken, again with conflicting results.

OBJECTIVES

To assess the effects of psychological interventions (educational, individual cognitive behavioural or psychotherapeutic, or group support) on psychological and survival outcomes for women with metastatic breast cancer.

SEARCH STRATEGY

We searched the Cochrane Breast Cancer Group Trials Register (September 2003), the Cochrane Central Register of Controlled Trials (The Cochrane Library, Issue 4, 2003), MEDLINE (1966-October 2003), CancerLit (1983-2000), CINAHL (1982-October 2003), PsycInfo (1974-November 2003), and SIGLE (1980-November 2003).

SELECTION CRITERIA

Randomised controlled trials (RCTs) of psychological interventions for women with metastatic breast cancer. Studies were included even if they were not 'intention to treat', owing to the nature of the patient group under study and the likely high loss of follow-up data.

DATA COLLECTION AND ANALYSIS

Data were extracted independently by two reviewers. Data about the nature and setting of the intervention, and the relevant outcome data were extracted, along with items relating to methodological quality.

MAIN RESULTS

Five primary studies were identified, all group psychological interventions. Two of these were cognitive behavioural interventions and three evaluated support-expressive group therapy. The five studies of group psychological therapies for women with metastatic breast cancer showed very limited evidence of benefit arising from these interventions. Although there was evidence of short-term benefit for some psychological outcomes, in general these were not sustained at follow-up. A clearer pattern of psychological outcomes could not be discerned as a wide variety of outcome measures and durations of follow-up were used in the included studies. The possible longer survival times in women allocated to receive psychological intervention in the early study have not been replicated in the subsequent four studies (including one by members of the first study group), and overall the effects of these interventions on survival are not statistically significant (for example, odds ratio for 5 year survival 0.83 (95% confidence interval [CI] 0.53 - 1.28).

REVIEWERS' CONCLUSIONS

There is insufficient evidence to advocate that group psychological therapies (either cognitive behavioural or supportive-expressive) should be made available to all women diagnosed with metastatic breast cancer. Any benefits of the interventions are only evident for some of the psychological outcomes and in the short term. The possibility of the interventions causing harm is not ruled out by the available data.
