Mind matters -- group therapy and survival in breast cancer

Intervenções Grupais para Mulheres com Câncer de Mama: Desafios e Possibilidades

Resumo Este estudo teve por objetivo analisar a produção científica nacional e internacional sobre os grupos de reabilitação psicossocial para mulheres com câncer de mama. O levantamento bibliográfico foi realizado a partir das bases indexadoras LILACS, PubMed, PsycINFO e CINAHL. Foram selecionados 28 artigos, publicados no período de 2000 a 2015, que constituíram o corpus do estudo. Os achados foram agrupados por meio de análise de conteúdo. Os resultados evidenciaram que os grupos de apoio podem resultar em benefícios psicossociais, como redução de estresse, incremento da qualidade de vida, melhora do humor e compartilhamento de informações sobre as diversas opções de tratamentos disponíveis. Conclui-se que participar de grupos de apoio está associado a melhores desfechos psicológicos, contudo, não há evidências que comprovem aumento na expectativa de vida das mulheres.

Change Is Complex: Rethinking Research on Psychosocial Interventions and Cancer

The widely discussed 1989 study by Spiegel and colleagues, which suggested that a psychosocial group intervention affected survival in metastatic breast cancer, was not replicated by Goodwin and colleagues in 2001. We analyze methodological issues in both studies, including issues of sampling, randomization, interpretation, and the adequacy and validity of psychosocial constructs and measures to assess hypothesized ingredients of change. The notion of psychogenicityis introduced, conceived as the ability of psychosocial interventions to elicit changes hypothesized to be linked to desired medical outcomes. These considerations lead to the conclusion that there is insufficient evidence to be able to generalize from either study for or against the notion that psychosocial interventions can affect survival in breast cancer. The failure to incorporate into research designs a comprehensive understanding of how coping patterns and related factors may interact with psychosocial interventions to influence cancer progression, and to address hypothesized mediating mechanisms is discussed. Finally, strategies are proposed for future biopsychosocial and intervention research in the field of biopsychooncology.

Relationship between negative mental adjustment to cancer and distress in thyroid cancer patients

PURPOSE

Previous studies have reported that over a third of cancer patients experience significant psychological distress with diagnosis and treatment of cancer. Mental adjustment to cancer as well as other biologic and demographic factors may be associated with their distress. We investigated the relationship between mental adjustment and distress in patients with thyroid cancer prior to thyroidectomy.

MATERIALS AND METHODS

One hundred and fifty-two thyroid cancer patients were included in the final analysis. After global distress levels were screened with a distress thermometer, patients were evaluated concerning mental adjustment to cancer, as well as demographic and cancer-related characteristics. A thyroid function test was also performed. Regression analysis was performed to discern significant factors associated with distress in thyroid cancer patients.

RESULTS

Our regression model was significant and explained 38.5% of the total variance in distress of this patient group. Anxious-preoccupation and helpless-hopeless factors on the mental adjustment to cancer scale were significantly associated with distress in thyroid cancer patients.

CONCLUSION

Negative emotional response to cancer diagnosis may be associated with distress in thyroid cancer patients awaiting thyroidectomy. Screening of mental coping strategies at the beginning of cancer treatment may predict psychological distress in cancer patients. Further studies on the efficacy of psychiatric intervention during cancer treatment may be needed for patients showing maladaptive psychological responses to cancer.

Tranceformations: hypnosis in brain and body

In this review, the role of hypnosis and related psychotherapeutic techniques are discussed in relation to the anxiety disorders. In particular, anxiety is addressed as a special form of mind/body problem involving reverberating interaction between mental and physical distress. The history of hypnosis as a therapeutic discipline is reviewed, after which neurobiological evidence of the effect of hypnosis on modulation of perception in the brain. Specific brain regions involved in hypnosis are reviewed, notably the dorsal anterior cingulate gyrus and the dorsolateral prefrontal cortex. The importance of hypnotizability as a trait, stable variability in hypnotic responsiveness, is discussed. Analogies between the hypnotic state and dissociative reactions to trauma are presented, and the uses of hypnosis in treating posttraumatic stress disorder, stressful situations, and phobias as well as outcome data are reviewed. Effects of hypnosis on control of somatic processes are discussed, and then effects of psychosocial support involving Supportive-Expressive Group Therapy and hypnosis on survival time for cancer patients are evaluated. The evidence indicates an important role for hypnosis in managing anxiety disorders and anxiety related to medical illness.

Cultural differences in use of an electronic discussion group

This article describes how 121 women newly diagnosed with breast cancer used a computer mediated discussion group to cope with their diagnosis. These data are part of a larger data set from a randomized clinical trial assessing the impact of a computer-based system called CHESS (the Comprehensive Health Enhancement Support System) on health outcomes. The larger study found significant improvement in health outcomes for those in the experimental group (those receiving CHESS), especially for women of color. Since discussion group is by far the most heavily used service of CHESS, one might conclude that these benefits (both overall and greater for women of color) should be attributed to amount of discussion group use. This study looks at how women of color and Caucasian women used the CHESS discussion group over the period of the study. Content analysis of messages in the discussion group showed that women of color used the discussion group differently from Caucasian women-they used it less frequently but their messages were more focused on breast cancer, suggesting they used discussion group more instrumentally.

Ethnicity and cultural models of recovery from breast cancer

OBJECTIVE

Recovery narratives describe the culturally shared understandings about the ideal or desirable way to recover from an illness experience. This paper examines ethnic differences in recovery narratives among women participating in breast cancer support groups in Central Florida, USA. It compares groups serving African-American, Latina, and European American women, with the objective of better understanding the appeal of ethnic-specific illness support groups for culturally diverse populations.

DESIGN

A mixed-method study design combined qualitative and quantitative measures, including in-depth interviews, participant observation at support group meetings, collection of printed documents, and a structured survey.

RESULTS

Core elements of the recovery narrative drew from the dominant societal cancer discourse of optimism and personal transformation through adversity; however, important ethnic differences were evident in the meaning assigned to these themes. Groups gave distinctive salience to themes of faith and spirituality, empowerment through the migration experience, and becoming a better person through the journey of recovery.

CONCLUSION

The findings suggest that ethnic cancer support groups draw upon dominant societal discourses about cancer, but they espouse distinctive recovery narratives that are consonant with the groups' cultural models of illness. Similarity between ethnic members' individual recovery narratives and that of the group may contribute to the appeal of ethnic illness support groups for culturally diverse populations.

On-line health companion contact among chronically ill in the Netherlands

A health companion is a patient who supports another patient or patient group with a similar health condition. Health companions deliver more and more support by the Internet. However, little is known about the characteristics of the users, their motivation, type of technology used and effects on health and the healthcare delivery process. The objective of the paper is to understand motivation, technology and effects of on-line health companion contact in the Netherlands concerning chronic diseases (DBM, COPD, CHF, CRD, CMD). The On-line Health Companion Contact Model was created to frame the research process. An extensive on-line questionnaire was taken from patients with various chronic disorders and using on-line health companion contact to obtain quantitative and qualitative data. Obtaining information was found the key motivation for applying on-line health companion contact and several characteristics play a role in the selection to use a specific website, including: closed access; the topics discussed; the easy use; the type of users and a clear structure. Respondents prefer website facilitated by a forum or social networking site. Other factors are the possibility to share experiences with other patients, to find recognition and understanding and to meet new people. These positive aspects are of greater importance than the perceived barriers including privacy concerns, negative stories and whining other users and concerns regarding the quality of information. On-line health companion contact can increase the quality of life and self-management because respondents perceived to be better informed, better able to accept their disease, better deal with their situation and to receive an increased amount of social support.

Historical threads in the development of oncology social work

As the Association of Oncology Social Work celebrates its 25th year, we pause to reflect on the many historical threads that contributed to its development and hear from each of the presidents who helped create the organization, as we know it today. Set within hospitals, medical social work was born in the early 20th century. In the 1940s medical social work became necessary for hospital accreditation. Two additional historical shifts, one in medical improvements in treating cancer, the other a shift to a consumer-oriented American Cancer Society, contributed to the push for a greater role for the federal government in funding cancer research. Oncology social work came to full blossom in the 1970s, a result of the physicians' need for a member of the health care team who understood cancer, its treatment, and the patient's need to address his or her psychosocial needs resulting from cancer. Today, oncology social work is a fully developed profession with a national organization providing education and support to oncology social workers' in their use of psychosocial interventions and research in behalf of cancer patients and their families.

Behavioral health services for women who have breast cancer

PURPOSE

To explore whether the use of behavioral health services (BHS) among women with breast cancer is influenced by how insurance plans administer these services, we compared utilization of psychotherapy and psychotherapeutic medications among women with breast cancer who received BHS coverage through a carve-out versus integrated arrangement.

PATIENTS AND METHODS

We analyzed insurance claims, enrollment data, and benefit design data from the MarketScan Commercial Claims & Encounters Research Database for the years 1998 to 2002 for women <or= 63 years old with newly diagnosed breast cancer. We compared the probability of receiving psychotherapy, the likelihood of receiving antidepressant/antianxiety/hypnotic medications, and the number of psychotherapy sessions used during the year after a breast cancer diagnosis among women whose behavioral health services were provided through carve-out versus integrated arrangements.

RESULTS

Women enrolled in carve-outs were significantly less likely to receive any psychotherapy visits compared with women in integrated arrangements (odds ratio, 0.68; P < .01). Conditional on having received psychotherapy, however, women in carve-out arrangements used more psychotherapy visits than women in integrated arrangements. The use of antianxiety/hypnotic drugs was significantly higher for women in carve-out arrangements versus women in integrated arrangements (36.1% v 32.6%, P < .05). Moreover, women who received psychotherapy were significantly more likely to received antidepressants and antianxiety/hypnotic medications (five and three times more likely, respectively).

CONCLUSION

The type of BHS arrangement was associated with the utilization of psychotherapy and psychotherapeutic medications among women with breast cancer.

Stress, immunity, and cervical cancer: biobehavioral outcomes of a randomized clinical trial [corrected]

PURPOSE

Cancer diagnosis and treatment imparts chronic stressors affecting quality of life (QOL) and basic physiology. However, the capacity to increase survival by improving QOL is controversial. Patients with cervical cancer, in particular, have severely compromised QOL, providing a population well-suited for the evaluation of novel psychosocial interventions and the exploration of mechanisms by which modulation of the psychoneuroimmune axis might result in improved clinical outcomes.

EXPERIMENTAL DESIGN

A randomized clinical trial was conducted in cervical cancer survivors that were enrolled at >or=13 and <22 months after diagnosis (n=50), comparing a unique psychosocial telephone counseling (PTC) intervention to usual care. QOL and biological specimens (saliva and blood) were collected at baseline and 4 months post-enrollment.

RESULTS

The PTC intervention yielded significantly improved QOL (P=0.011). Changes in QOL were significantly associated with a shift of immune system T helper type 1 and 2 (Th1/Th2) bias, as measured by IFN-gamma/interleukin-5 ELISpot T lymphocyte precursor frequency; improved QOL being associated with increased Th1 bias (P=0.012). Serum interleukin-10 and the neuroendocrine variables of cortisol and dehydroepiandrosterone revealed trends supporting this shift in immunologic stance and suggested a PTC-mediated decrease of the subject's chronic stress response.

CONCLUSIONS

This study documents the utility of a unique PTC intervention and an association between changes in QOL and adaptive immunity (T helper class). These data support the integration of the chronic stress response into biobehavioral models of cancer survivorship and suggests a novel mechanistic hypotheses by which interventions leading to enhanced QOL could result in improved clinical outcome including survival.

Effects of psychological interventions on neuroendocrine hormone regulation and immune status in HIV-positive persons: a review of randomized controlled trials

We reviewed randomized controlled trials (RCTs) that examined the effects of psychological interventions on HIV disease markers including neuroendocrine hormone regulation and immune status. Utilizing both PubMed and PsycINFO, we searched for RCTs published over the past 20 years (1987-2007). Of the 31 RCTs identified, 14 tested effects of psychological interventions on neuroendocrine regulation or immune status. Despite the fact that there are significant methodological limitations of RCTs that have been conducted to date, psychological interventions for HIV-positive persons have been shown to be efficacious in improving psychological adjustment compared with wait-list or treatment as usual control conditions. However, there is little support for differential efficacy of group-based interventions that have been tested to date, even in comparison with semistructured social support groups. Irrespective of the treatment modality, it seems that interventions that are successful in improving psychological adjustment are more likely to have salutary effects on neuroendocrine regulation and immune status. Psychological interventions represent a viable adjuvant treatment that can assist patients with improving psychological adjustment and potentially enhancing immune status. To inform the development of innovative treatments with potentially superior efficacy, deconstruction trials are necessary to examine the effects of distinct components of multimodal psychological interventions compared with nonspecific social support effects. Effectiveness trials of promising psychological interventions with more representative samples of HIV-positive persons are also needed to provide more definitive information on the clinical utility and potential cost-effectiveness of treatments that have been developed to date.

Use of therapeutic factors for the evaluation of results in support groups

OBJECTIVE: To identifyg the evidence of Therapeutic Factors (TF) for the systematized evaluation of a support group. METHODS: Descriptive study developed in a hospital in Goiânia GO, in 2005/2006. Ten sessions of the Inpatient Family Support Group (GRAF) were registered with a digital recorder, field journal and a check list filled out by the coordinators in order to identify TF observed in the participation of each family member. Later, these records were cross-checked so as to analyze this participation. RESULTS: GRAF had an average of 6.9 participants per session. The following TF were identified: universality, imparting of information, cohesiveness, existential factors and instillation of hope. CONCLUSION: These TF were useful in the evaluation of the GRAF results, suggesting their convenience to evaluate results in other support groups.

Hope

Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH), founded The Kenneth B. Schwartz Center at MGH. The Schwartz Center is a nonprofit organization dedicated to supporting and advancing compassionate health care delivery that provides hope to the patient, support to caregivers, and encourages the healing process. The Center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum where caregivers reflect on important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from fellow staff members. A patient with recurrent ovarian cancer, now in a 12-year remission after recurrence, and her surgeon, discussed their experiences and feelings around the hopes and fears of cancer and its treatment. Hope sustains many through dark times, and is at the core of the wonderful resilience of many who wrestle with cancer. Concerns about false hope, unrealistic expectations, assumptions, engaging in realistic hopefulness, and the joys and stresses embodied in hope and how they frame the caregiver-patient relationship are discussed. The literature and limited evidence base are reviewed.

Cancer support groups: a critical review of empirical studies

Support groups for adults affected by cancer are widely offered by local community and national agencies in North America. This type of psychosocial intervention is defined in terms of its structure and functions, and its theoretical underpinnings and models of practice are described. Forty-four empirical studies of professionally led cancer support groups are summarized and critically reviewed. These studies include 32 outcome evaluations of randomized controlled trials, two process evaluations, and 10 consumer satisfaction studies. The findings reveal high levels of consumer satisfaction, and the outcome evaluations substantiate the morale and other quality of life benefits short of prolonging life. Discussion centers on priorities for future research and practice.

Impact of psychotherapeutic support for patients with gastrointestinal cancer undergoing surgery: 10-year survival results of a randomized trial

PURPOSE

The impact of psychotherapeutic support on survival for patients with gastrointestinal cancer undergoing surgery was studied.

PATIENTS AND METHODS

A randomized controlled trial was conducted in cooperation with the Departments of General Surgery and Medical Psychology, University Hospital of Hamburg, Germany, from January 1991 to January 1993. Consenting patients (N = 271) with a preliminary diagnosis of cancer of the esophagus, stomach, liver/gallbladder, pancreas, or colon/rectum were stratified by sex and randomly assigned to a control group that received standard care as provided on the surgical wards, or to an experimental group that received formal psychotherapeutic support in addition to routine care during the hospital stay. From June 2003 to December 2003, the 10-year follow-up was conducted. Survival status for all patients was determined from our own records and from three external sources: the Hamburg cancer registry, family doctors, and the general citizen registration offices.

RESULTS

Kaplan-Meier survival curves demonstrated better survival for the experimental group than the control group. The unadjusted significance level for group differences was P = .0006 for survival to 10 years. Cox regression models that took TNM staging or the residual tumor classification and tumor site into account also found significant differences at 10 years. Secondary analyses found that differences in favor of the experimental group occurred in patients with stomach, pancreatic, primary liver, or colorectal cancer.

CONCLUSION

The results of this study indicate that patients with gastrointestinal cancer, who undergo surgery for stomach, pancreatic, primary liver, or colorectal cancer, benefit from a formal program of psychotherapeutic support during the inpatient hospital stay in terms of long-term survival.

Social support among women who died of ovarian cancer

GOALS OF WORK

We investigated the effects of social support in the last 6 months of life for women who died of ovarian cancer.

MATERIALS AND METHODS

The study population included women enrolled in one of three Managed Care Organizations who died of ovarian cancer (1995-2000). Information was collected on demographics, living environment, presence of escorts to oncology encounters, comorbidities, medications, outpatient and inpatient encounters, and referrals to home health and hospice. Two characteristics of social support were examined: living with others and being escorted to one or more oncology visits.

RESULTS

Of 421 subjects, both aspects of social support were known for 345 (82%). Of these, 227 (66%) lived with others and were escorted, 33 (10%) lived with others but were never escorted, 59 (17%) lived alone but were escorted, and 26 (8%) lived alone and never were accompanied. Women living alone were less likely to be taking a psychotropic medication (57% vs 70%, p = 0.021) and were somewhat less likely to receive hospice referral (42% vs 53%, p = 0.054). Women who were never escorted had fewer outpatient encounters (12.60 vs 15.77, p = 0.033) and were less likely to be referred to home health (18% vs 30%, p = 0.046).

CONCLUSIONS

This study indicates that social support has some beneficial effects on receipt of personal health services. Friends and family may act as proponents for the patient in obtaining services. Health care professionals should be encouraged to assess the cancer patient's social situation and identify areas where help may be needed.

Immediate placebo effect in Parkinson's disease--is the subjective relief accompanied by objective improvement?

BACKGROUND

A recent well-conducted meta-analysis showed that placebo effect is associated with a possible small benefit for subjective outcomes, but has no significant effects on objective outcomes.

OBJECTIVE

Herein, we aimed to investigate the immediate effects of two different types of placebo [placebo pill and sham transcranial magnetic stimulation (TMS)] in Parkinson's disease (PD) patients and compared them to the standard treatment (levodopa) in a proper randomized, double-blind, crossover clinical trial.

METHODS

PD patients received three different interventions on different days: levodopa, placebo pill, and sham TMS. The motor function was assessed using simple and choice reaction time, Unified Parkinson's Disease Rating Scale (UPDRS), finger tapping, Purdue Pegboard test, time to button up, walking time and supination-pronation. The subjective motor function was measured by a visual analogue scale (VAS).

RESULTS

The results showed that there was a significant motor function in the motor function only after the treatment with levodopa, but not after treatment with placebo pills or sham TMS. However, patients reported a similar subjective improvement in motor function indexed by VAS following these three treatments.

CONCLUSION

These results suggest that placebo interventions in PD may have an immediate subjective sensation of improvement but result in no significant objective motor changes compared with levodopa treatment. Although physiological changes are possible after a placebo intervention, our findings suggest that the acute placebo effect in PD may be the result of the subjective change in the motor rating only.

[The specific placebo effect]

Placebo effects are considered a relevant component of any therapeutic intervention. At the same time clinical researchers try to control for them as if they were unspecific noise which cannot be differentiated any further. This article shows that the evidence for clinically relevant placebo effects is contradictory. The author believes that these contradictions are mainly due to the misleading terms and concepts of placebo, specific and unspecific effects. A model interpreting all effects of an intervention (excluding spontaneous changes and measurement error) as specific (having a clear-cut mechanism and a size depending on the specific conditions) is proposed. The part of the total effect caused by the postulated mechanism (the specific effect in common terms) is interpreted as attributable while the other parts are considered associated effects. The size of associated effects depends on the characteristics of interventions, patients and providers. This model would better explain the contradictory results reported in placebo research. Further implications for research and health care decision making are discussed.

Psychological resources protect health: 5-year survival and immune function among HIV-infected women from four US cities

OBJECTIVE

Guided by Cognitive Adaptation Theory, the aim was to determine whether psychological resources (positive affect, positive expectancy regarding health outcomes, finding meaning in challenging circumstances) protect against HIV-related mortality and decline in CD4 lymphocyte counts among women with HIV.

DESIGN

The HIV Epidemiologic Research Study, a longitudinal prospective cohort study, with semi-annual interview, physical examination and laboratory assays.

METHODS

A total of 773 HIV-seropositive women aged 16 to 55 years were recruited from four academic medical centers in Baltimore, Maryland; Bronx, New York; Providence, Rhode Island; and Detroit, Michigan. Semi-annually for up to 5 years, the women were interviewed, underwent physical examination, medical record abstraction, and venipuncture. Primary outcomes for these analyses included HIV-related mortality and CD4 cell count slope decline over 5 years.

RESULTS

Psychological resources were inversely associated with HIV-related mortality and time to death, beyond the effects of potential confounding variables such as clinical status (e.g., HIV viral load, symptoms, antiretroviral therapy), sociodemographic characteristics (e.g. age, race), and depression at study entry (P < 0.05). Psychological resources also were inversely associated with CD4+ cell count decline (P < 0.01), serving as a possible mechanism linking resources to mortality.

CONCLUSIONS

Psychological resources may protect against HIV-related mortality and immune system decline. Findings have implications for understanding individual variability in HIV disease progression. Moreover, because psychological resources are potentially amenable to change, results can be applied to clinical interventions aimed at improving the health of women with HIV.

Exploring the multidimensional benefits of breast cancer support groups

Utilizing a more representative sample than previous research, this study examines differences in breast cancer survivors' social, psychological, and physical quality of life by participation in breast cancer support groups. This research also explores whether all breast cancer survivors who participate in breast cancer support groups are benefiting equally. The sample includes 958 women of Eastern North Carolina (26% African American, 73% Caucasian) diagnosed with breast cancer who completed interviews concerning their experience with the disease, as well as their social, psychological, and physical well-being. Support group participation was found to have a significant positive affect on social and overall QOL; yet these affects on social QOL were found to be insignificant, and merely marginally significant concerning overall QOL when controlling for sociodemographics, other social support networks, and disease characteristics. Significant differences were found in the characteristics of participants and non-participants of breast cancer support groups and a number of these differences were found to have significant affects on QOL. These findings suggest that future research needs to investigate the relationships between participation in a breast cancer support group and measures of QOL while controlling for potential confounding factors.

Influence of psychological response on breast cancer survival: 10-year follow-up of a population-based cohort

The possibility that psychological response within a few weeks of a breast cancer diagnosis can influence the outcome of the disease is a contentious issue. Psychological response, including helplessness/hopelessness, fighting spirit and depression was assessed in early-stage breast cancer patients between 1 and 3 months post-diagnosis, in order to ascertain effect on cancer prognosis. Patients were followed up for a period of 10 years in order to clarify the effect of psychological response on disease outcome. After 10 years, there is a continuing effect of helplessness/hopelessness on disease-free survival (adjusted hazard ratio (HR) 1.53, 95% confidence interval (CI) 1.11-2.11) but not of depression (adjusted HR for overall survival for 'cases' 2.43, 95% CI 0.97-6.10). Longer follow-up also indicates that a high fighting spirit confers no survival advantage. The results showed that, in patients who were disease-free at 5 years, their baseline helpless/hopeless response still exerted a significant effect on disease-free survival beyond 5 (and up to 10) years. The effect is therefore maintained for up to 10 years of follow-up. Clinicians may wish to screen for helplessness around the time of diagnosis in order to target psychological care resources. Further large studies, with similarly prolonged follow-up, are needed to replicate this effect and clarify its mechanism of action.

The impact of social support on end-stage renal disease

Social support is a concept recognizing patients exist to varying degrees in networks through which they can receive and give aid, and in which they engage in interactions. Social support can be obtained from family, friends, coworkers, spiritual advisors, health care personnel, or members of one's community or neighborhood. Several studies have demonstrated that social support is associated with improved outcomes and improved survival in several chronic illnesses, including cancer and end-stage renal disease (ESRD). The mechanism by which social support exerts its salutary effects are unknown, but practical aid in achieving compliance, better access to health care, improved psychosocial and nutritional status and immune function, and decreased levels of stress may all play key roles. Few data exist regarding social support in patients with ESRD and chronic renal insufficiency, but links between social support and depressive affect and quality of life have been established. Interventions that enhance social support in ESRD patients should be evaluated.

Cultural models of illness and recovery in breast cancer support groups

In an ethnographic study of breast cancer support groups for white women, the authors describe the cultural model of illness and recovery espoused by the groups and examine contested areas that might influence participation. Through analysis of interviews, observation at meetings, and program documents, they develop a model of group culture that includes five components: recovery narrative, group metaphors, perceived benefits, group processes, and contested domains. The recovery narrative focuses on optimism and personal growth, and members invoke metaphors of family and sisterhood to describe their relationship to the group. Linkages are made between perceived benefits and group processes. Contested domains challenge dominant features of the recovery narrative. The authors discuss the value of cultural studies of illness support groups for understanding member-group fit.

Medicare cost in matched hospice and non-hospice cohorts

Hospice care is perceived as enhancing life quality for patients with advanced, incurable illness, but cost comparisons to non-hospice patients are difficult to make. The very large Medicare expenditures for care given during the end of life, combined with the pressure on Medicare spending, make this information important. We sought to identify cost differences between patients who do and do not elect to receive Medicare-paid hospice benefits. We introduce an innovative prospective/retrospective case-control method that we used to study 8,700 patients from a sample of 5% of the entire Medicare beneficiary population for 1999-2000 associated with 16 narrowly defined indicative markers. For the majority of cohorts, mean and median Medicare costs were lower for patients enrolled in hospice care. The lower costs were not associated with shorter duration until death. For important terminal medical conditions, including non-cancers, costs are lower for patients receiving hospice care. The lower cost is not associated with shorter time until death, and appears to be associated with longer mean time until death.

Meta-analysis of the effects of psychosocial interventions on survival time in cancer patients

OBJECTIVE

To provide a quantitative summary of effects of psychosocial interventions on cancer survival, and to present an overview of methodological and reporting aspects of the studies.

METHOD

Electronic searches and manual searches of reference lists from review articles and retrieved papers. Two coders independently coded study, participant, treatment, and outcome characteristics of the studies meeting selection criteria.

RESULTS

Thirteen journal articles published between 1989 and 2003 reporting results from 14 controlled intervention studies were included. Results are based on data obtained from 2626 subjects. Effect sizes [hazard ratios (HR)] were heterogeneous and random effects models were used in the analyses. The total mean inverse-variance-weighted HR was 0.85 (95% CI: 0.65-1.11). Randomized studies (n=8) showed no overall treatment effect (HR: 0.77, 95% CI: 0.56-1.06), neither did the nonrandomized studies (HR: 1.00, 95% CI: 0.61-1.62). Interventions using individual treatment (n=3) were, however, found to be effective (HR: 0.55, 95% CI: 0.43-0.70) but interventions using group treatment (n=9) were ineffective (HR: 0.97, 95% CI: 0.73-1.27). Group treatments of breast cancer (n=6) were ineffective (HR: 0.95, 95% CI: 0.69-1.31).

CONCLUSION

A definite conclusion about whether psychosocial interventions prolong cancer survival seems premature. Future studies should use randomization to avoid self-selection of patients with poor prognosis. Interventions should focus on a single diagnosis, take into account known risk factors, and describe their interventions thoroughly.

Cancer supportive care, improving the quality of life for cancer patients. A program evaluation report

GOALS OF WORK

As medical care for cancer has become more specialized in diagnosis, treatment has become more technical and fragmented. In order to help cancer patients and their families, we developed a coordinated program called the Stanford Cancer Supportive Care Program (SCSCP) at the Center for Integrative Medicine at Stanford Hospital and Clinics. The Stanford Cancer Supportive Care Program was initiated in 1999 to provide support for cancer patients, addressing the need for improved physical and emotional well-being and quality of life. This paper is a program evaluation report.

PATIENTS AND METHODS

The number of patient visits grew from 421 in 1999 to 6319 in 2002. This paper describes the utilization of the SCSCP program as assessed by 398 patient visit evaluations during a 9-week period, January 2002 to March 2002. During this time we collected attendance records with demographic data and anonymous questionnaires evaluating each program. Patients were asked to evaluate how the program helped them regarding increase of energy, reduction in stress, restful sleep, pain reduction, sense of hopefulness, and empowerment.

MAIN RESULTS

Over 90% of the patients using the SCSCP felt there was benefit to the program. Programs were chosen based on a needs assessment by oncologists, nurse managers, social workers, and patients. Massage, yoga, and qigong classes had the highest number of participants. Qualitative data showed benefit for each program offered.

CONCLUSIONS

This evaluation of a free cancer supportive care program initiated in a hospital outpatient setting provides initial evidence of patient satisfaction and improvement in quality of life.

How the mind hurts and heals the body

The author reviews some of the social and behavioral factors acting on the brain that influence health, illness, and death. Supported with data from several areas of research, his proposal for understanding health and illness provides both the concepts and the mechanisms for studying and explaining mind-body relationships. The brain is the body's first line of defense against illness, and the mind is the emergent functioning of the brain. This mind-body approach incorporates ideas, belief systems, and hopes as well as biochemistry, physiology, and anatomy. Changing thoughts imply a changing brain and thus a changing biology and body. Belief systems provide a baseline for the functioning brain upon which other variables act and have their effects.

Does psychosocial intervention improve survival in cancer? A meta-analysis

BACKGROUND

There is growing evidence that positive psychosocial intervention improves the wellbeing of cancer patients. Two meta-analyses conducted to date confirmed a significant small-to-moderate effect on quality of life. Previous randomized trials reported that psychosocial intervention also improved survival. However, more recent trials failed to detect a difference in survival. A systematic review of randomized trials that have examined the effectiveness of psychosocial intervention in cancer patients in terms of survival prolongation was conducted.

METHODS

Randomized trials published between 1966 and June 2002 were identified through the databases of MEDLINE, EMBASE, CancerLit, CINAHL, Cochrane Library and reference lists of relevant articles. Relevant data were abstracted. The results of randomized trials were pooled using meta-analyses to estimate the effect of treatment on overall survival at one and four years in all cancer patients and also in breast cancer patients with metastases.

RESULTS

Eight trials, which involved a total of 1062 patients (all cancer histologies), were identified. One- and four-year overall survival rates were obtained from eight trials and six trials, respectively. There was no statistically significant difference in the overall survival rates at one and four years [P = 0.6; RR 0.94 (95% CI 0.72, 1.22)] and [P = 0.5; RR 0.93 (95% CI 0.77, 1.13)], respectively. Four trials examined 511 metastatic breast cancer patients. Again, there was no statistically significant difference in the overall survival rates at one and four years [P = 0.3; RR 0.87 (95% CI 0.67, 1.14)] and [P = 0.3; RR 0.91 (95% CI 0.76, 1.10)], respectively.

CONCLUSIONS

Psychosocial intervention does not prolong survival in cancer. This meta-analysis can not rule out small effect sizes because of the small number of trials and small trial sizes.

The effect of pain on survival

For patients suffering various diseases, increased pain hastens death by interfering with life-enhancing activities; if it hurts to eat, patients won't eat; if it hurts to move, they won't move. But survival simply cannot be enhanced by reducing pain because, even as some pain treatments have a beneficial effect on disease (spinal cord stimulation on coronary artery disease, for example), other pain treatments can have an adverse effect on survival. Thus, we must continue to investigate pain and its treatment even as we use the best possible techniques available to treat pain as aggressively as we would any other disease.

Patients' rights, quality of life, and health care system performance

The purpose of this paper is to promote the development of a social contract between patient and clinician that permits patients to state how they want to live as they survive rather than what they are willing to lose to extend their survival. To do this, patients must have sufficient leverage to affect the nature of the care they receive. This leverage, it is proposed, can be achieved by first making a 'Declaration of Patients' Rights Relative to Their Quality of Life' and then evaluating the extent to which the patient's providers comply with this rights statement. The paper also reviews The World Health Report 2000 [Health Systems: Improving Performance Geneva: WHO, 2000] as an example of an alternative approach to defining a health care social contract and evaluating a health system's performance. Also discussed, were steps that could be taken to facilitate the integration of the patients' rights statement into medical practice and health care systems performance.

‘Being positive’: perceptions of patients with cancer and their nurses

BACKGROUND

A review of popular literature reveals a constant message about the healing power of 'being positive'. While there are studies that have examined the link between psychosocial factors such as attitude and cancer survival, very little has been reported about the perceptions of patients and nurses on the meaning of 'being positive'.

AIM

To explore the meaning of 'being positive' for patients undergoing cancer treatment and for nurses who care for them.

METHODS

A qualitative, descriptive approach within the paradigm of constructivist inquiry was used. Semi-structured interviews were conducted with a self-selected convenience sample of 11 patients and eight nurses. The interviews addressed the following key concepts: definitions of 'being positive' and being negative; how these attributes are manifest in cancer patients; and factors influencing patient attitudes.

FINDINGS

Patients defined 'being positive' as maintaining some sort of normality without letting cancer have a detrimental effect on daily living. Nurses identified hope, acceptance, fighting spirit and looking on the bright side as definitions of 'being positive'. Nurses and patients identified environment and support of family, friends and health professionals as factors that influence patient attitudes. Patients also identified other peoples' attitudes as important.

CONCLUSIONS

'Being positive' must be acknowledged as central to being able to cope with cancer and its treatment. The ability of nurses to care for patients with cancer and help them to remain positive will be improved if they develop a better understanding of the meaning of 'being positive' for patients, and how other peoples' attitudes affect their state of mind.

Depression and cancer: mechanisms and disease progression

Depression and cancer commonly co-occur. The prevalence of depression among cancer patients increases with disease severity and symptoms such as pain and fatigue. The literature on depression as a predictor of cancer incidence is mixed, although chronic and severe depression may be associated with elevated cancer risk. There is divided but stronger evidence that depression predicts cancer progression and mortality, although disentangling the deleterious effects of disease progression on mood complicates this research, as does the fact that some symptoms of cancer and its treatment mimic depression. There is evidence that providing psychosocial support reduces depression, anxiety, and pain, and may increase survival time with cancer, although studies in this latter area are also divided. Psychophysiological mechanisms linking depression and cancer progression include dysregulation of the hypothalamic-pituitary-adrenal axis, especially diurnal variation in cortisol and melatonin. Depression also affects components of immune function that may affect cancer surveillance. Thus, there is evidence of a bidirectional relationship between cancer and depression, offering new opportunities for therapeutic intervention.

Evaluation of support groups for women with breast cancer: importance of the navigator role

BACKGROUND

At least some forms of breast cancer are increasingly being viewed as a chronic illness, where an emphasis is placed on meeting the various ongoing needs of people living with cancer, their families and other members of their social support networks. This commentary outlines some approaches to the evaluation of cancer-related support groups, with a particular emphasis on those designed to provide long-distance support, via the internet, for women with breast cancer.

DISCUSSION

The literature on evaluations of community-based cancer support groups indicates that they offer a number of benefits, and that it is more reasonable to expect an impact of such interventions on psychosocial functioning and/or health-related quality of life than on survival. The literature on both face-to-face and online social support groups suggests that they offer many advantages, although evaluation of the latter delivery mechanism presents some ethical issues that need to be addressed. Many popular online support groups are peer-moderated, rather than professionally-moderated. In an evaluation of online support groups, different models of the role of the "navigator" need to be taken into account. Some conceptual models are outlined for the evaluation of the "navigator role" in meeting the informational, decisional and educational needs of women with breast cancer. The Breast-Cancer Mailing List, an example of an unmoderated internet-based peer-support group, is considered within the context of a Shared or Tacit Model of the navigator role.

CONCLUSION

Application of the concept of a "navigator role" to support groups in general, and to unmoderated online ones in particular, has received little or no attention in the research literature. The navigator role should be taken into account in research on this increasingly important aspect of cancer communication.

Virtual connections: Internet health care

Shortly before his death in 1995, Kenneth B. Schwartz, a cancer patient at Massachusetts General Hospital (MGH), founded The Kenneth B. Schwartz Center at MGH. The Schwartz Center is a nonprofit organization dedicated to supporting and advancing compassionate health care delivery that provides hope to the patient, support to caregivers, and encourages the healing process. The Center sponsors the Schwartz Center Rounds, a monthly multidisciplinary forum where caregivers reflect on important psychosocial issues faced by patients, their families, and their caregivers, and gain insight and support from fellow staff members. The 20th century success of the Internet is now translating into changes in 21st century medical practice. The changes brought about by the Internet have at once facilitated and complicated the practice of medicine. Physicians and patients are challenged to take advantage of the increased opportunities afforded by Internet access while being mindful of its drawbacks and the limitations to virtual communication. The case of Karen Parles, one of the authors, is presented. Karen developed locally advanced lung cancer and used the Internet to research her diagnosis. She found the information on lung cancer limited and confusing, and, in response, developed a website devoted to empowering lung cancer patients in their search for information and support (http://www.lungcanceronline.org). Here we discuss issues surrounding patients' use of the Internet for health information and communication with health care providers. The value of information-seeking as a coping mechanism is debated, and concerns are raised regarding confidentiality of electronic communications and the logistics of physicians adopting e-mail as a mechanism for communicating with patients.

Loneliness and pathways to disease

Social isolation predicts morbidity and mortality from cancer, cardiovascular disease, and a host of other causes. The mechanisms by which the social world impacts on health are poorly understood, in part because of lack of specificity in the conceptualization and operationalization of relevant aspects of social relationships and physiological processes. Perceived social isolation, commonly termed loneliness, may represent a link between the epidemiological and biological levels of analysis. Research is presented that investigates loneliness as a social factor of importance in three predisease pathways: health behaviors, excessive stress reactivity, and inadequate or inefficient physiological repair and maintenance processes. Empirical evidence of autonomic, endocrine, and immune functioning suggests that the physiological effects of loneliness unfold over a relatively long time period. For cancer patients, interventions should be aimed at providing instrumental support for the immediate demands of the disease.

Biobehavioral outcomes following psychological interventions for cancer patients

Psychological interventions for adult cancer patients have primarily focused on reducing stress and enhancing quality of life. However, there has been expanded focus on biobehavioral outcomes--health behaviors, compliance, biologic responses, and disease outcomes--consistent with the Biobehavioral Model of cancer stress and disease course. The author reviewed this expanded focus in quasiexperimental and experimental studies of psychological interventions, provided methodologic detail, summarized findings, and highlighted novel contributions. A final section discussed methodologic issues, research directions, and challenges for the coming decade.

The efficacy of a mind-body-spirit group for women with breast cancer: a randomized controlled trial

Increasing numbers of women with breast cancer are seeking alternatives to standard group support in coping with their illness. This study examines outcomes for 181 women with breast cancer randomized to either a 12-week standard group support or a 12-week complementary and alternative medicine (CAM) support intervention. Participants in the CAM group were taught the use of meditation, affirmation, imagery and ritual. The standard group combined cognitive-behavioral approaches with group sharing and support. Both interventions were found to be associated with improved quality of life (CAM, P=0.008; Standard, P=0.006), decreased depression (CAM, P=0.004; Standard, P=0.02), decreased anxiety (CAM, P=0.0003; Standard, P=0.02) and increased "spiritual well-being" (CAM, P=002; Standard, P=0.003). Only the CAM group showed increases in measures of Spiritual Integration (P=0.001) which were also significant between groups (P=0.003). The Standard group was associated with decreased confusion (P=0.01) and decreased helplessness/hopelessness (P=0.01), while the CAM group was associated with decreased avoidance (P=0.01). None of these latter changes were significant between groups. At baseline, very high correlations were noted between measures of quality of life, mood, and spiritual integration. At the end of the intervention, the CAM group showed higher satisfaction (P=0.006) and fewer dropouts (P=0.006) compared to the standard group. Better outcomes in quality of life in the CAM group were associated with lower initial fighting spirit (r=-.39, P=0.001). No baseline factors predicted better outcomes in the Standard group. In summary, the study found equivalence on most psychosocial outcomes between the two interventions.
