TL;DR: Supportive-expressive group therapy does not prolong survival in women with metastatic breast cancer, but it improves mood and the perception of pain, particularly in women who are initially more distressed.
Abstract: Background Supportive–expressive group therapy has been reported to prolong survival among women with metastatic breast cancer. However, in recent studies, various psychosocial interventions have not prolonged survival. Methods In a multicenter trial, we randomly assigned 235 women with metastatic breast cancer who were expected to survive at least three months in a 2:1 ratio to an intervention group that participated in weekly supportive–expressive group therapy (158 women) or to a control group that received no such intervention (77 women). All the women received educational materials and any medical or psychosocial care that was deemed necessary. The primary outcome was survival; psychosocial function was assessed by self-reported questionnaires. Results Women assigned to supportive–expressive therapy had greater improvement in psychological symptoms and reported less pain (P=0.04) than women in the control group. A significant interaction of treatment-group assignment with base-line psychological scor...

TL;DR: The author argues that all 3 variables that assess different aspects of social relationships are associated with health outcomes, that these variables each influence health through different mechanisms, and that associations between these variables and health are not spurious findings attributable to the authors' personalities.
Abstract: The author discusses 3 variables that assess different aspects of social relationships—social support, social integration, and negative interaction. The author argues that all 3 are associated with health outcomes, that these variables each influence health through different mechanisms, and that associations between these variables and health are not spurious findings attributable to our personalities. This argument suggests a broader view of how to intervene in social networks to improve health. This includes facilitating both social integration and social support by creating and nurturing both close (strong) and peripheral (weak) ties within natural social networks and reducing opportunities for negative social interaction. Finally, the author emphasizes the necessity to understand more about who benefits most and least from socialconnectedness interventions.

TL;DR: It is concluded that the existence of social networks means that people's health is interdependent and that health and health care can transcend the individual in ways that patients, doctors, policy makers, and researchers should care about.
Abstract: People are interconnected, and so their health is interconnected. In recognition of this social fact, there has been growing conceptual and empirical attention over the past decade to the impact of social networks on health. This article reviews prominent findings from this literature. After drawing a distinction between social network studies and social support studies, we explore current research on dyadic and supradyadic network influences on health, highlighting findings from both egocentric and sociocentric analyses. We then discuss the policy implications of this body of work, as well as future research directions. We conclude that the existence of social networks means that people's health is interdependent and that health and health care can transcend the individual in ways that patients, doctors, policy makers, and researchers should care about.

TL;DR: The evidence that various cellular and molecular immunological factors are compromised in chronic stress and depression is overviewed and the clinical implications of these factors in the initiation and progression of cancer are discussed.
Abstract: The links between the psychological and physiological features of cancer risk and progression have been studied through psychoneuroimmunology. The persistent activation of the hypothalamic-pituitary-adrenal (HPA) axis in the chronic stress response and in depression probably impairs the immune response and contributes to the development and progression of some types of cancer. Here, we overview the evidence that various cellular and molecular immunological factors are compromised in chronic stress and depression and discuss the clinical implications of these factors in the initiation and progression of cancer. The consecutive stages of the multistep immune reactions are either inhibited or enhanced as a result of previous or parallel stress experiences, depending on the type and intensity of the stressor and on the animal species, strain, sex, or age. In general, both stressors and depression are associated with the decreased cytotoxic T-cell and natural-killer-cell activities that affect processes such as immune surveillance of tumours, and with the events that modulate development and accumulation of somatic mutations and genomic instability. A better understanding of the bidirectional communication between the neuroendocrine and immune systems could contribute to new clinical and treatment strategies.

TL;DR: A growing body of evidence suggests that biological mechanisms underlie a bidirectional link between mood disorders and many medical illnesses and there is evidence to suggest that mood disorders affect the course of medical illnesses.

TL;DR: This review integrates clinical, cellular and molecular studies to provide a mechanistic understanding of the interface between biological and behavioural influences in cancer, and identifies novel behavioural or pharmacological interventions that might help improve cancer outcomes.
Abstract: Stress does not cause cancer per se, but depression and a lack of social support might influence cancer progression and clinical outcome. Can identification of the molecular and biological mechanisms involved be used to improve patient treatment? Epidemiological studies indicate that stress, chronic depression and lack of social support might serve as risk factors for cancer development and progression. Recent cellular and molecular studies have identified biological processes that could potentially mediate such effects. This review integrates clinical, cellular and molecular studies to provide a mechanistic understanding of the interface between biological and behavioural influences in cancer, and identifies novel behavioural or pharmacological interventions that might help improve cancer outcomes.

TL;DR: Psychiatric interventions that enhance effective coping and reduce affective distress appear to have beneficial effects on survival but are not proposed as an alternative or independent treatment for cancer or any other illness or disease.
Abstract: Objectives: We evaluated recurrence and survival for 68 patients with malignant melanoma who participated in a 6-week structured psychiatric group intervention 5 to 6 years earlier, shortly after their diagnosis and initial surgical treatment. We also explored the role of several factors as possible predictors of outcome. Design: This was a randomized controlled experimental study. The Cox proportion hazards regression model was used to quantify the relationship between treatment and the outcomes adjusted by the covariates (age, sex, Breslow depth, tumor site, baseline Profile of Mood States Total Mood Disturbance, baseline active-behavioral coping, baseline natural killer cell activity, and treatment [ie, group intervention]). The stepwise procedure was used for covariate selection. Results: For control patients, there was a trend for recurrence (13/34) and a statistically significant greater rate of death (10/34) than for experimental patients (7/34 and 3/34, respectively). We found that being male and having a greater Breslow depth predicted greater recurrence and poorer survival. Analysis of multiple covariates found that only Breslow depth and treatment (ie, group intervention) were significant. Adjusting for Breslow depth, treatment effect remained significant. Finally, baseline affective distress and baseline coping were significant psychobehavioral predictors for recurrence and survival. Surprisingly, higher levels of baseline distress as well as baseline coping and enhancement of active-behavioral coping over time were predictive of lower rates of recurrence and death. Conclusion: Psychiatric interventions that enhance effective coping and reduce affective distress appear to have beneficial effects on survival but are not proposed as an alternative or independent treatment for cancer or any other illness or disease. However, the exact nature of this relationship warrants further investigation.

TL;DR: Objective evidence is provided that a supportive group intervention for patients with metastatic cancer results in psychological benefit and mechanisms underlying the effectiveness of this group intervention are explored.
Abstract: • The effects of weekly supportive group meetings for women with metastatic carcinoma of the breast were systematically evaluated in a one-year, randomized, prospective outcome study. The groups focused on the problems of terminal illness, including improving relationships with family, friends, and physicians and living as fully as possible in the face of death. We hypothesized that this intervention would lead to improved mood, coping strategies, and self-esteem among those in the treatment group. Eighty-six patients were tested at four-month intervals. The treatment group had significantly lower mooddisturbance scores on the Profile of Mood States scale, had fewer maladaptive coping responses, and were less phobic than the control group. This study provides objective evidence that a supportive group intervention for patients with metastatic cancer results in psychological benefit. Mechanisms underlying the effectiveness of this group intervention are explored.

TL;DR: Supportive-expressive therapy, with its emphasis on providing support and helping patients face and deal with their disease-related stress, can help reduce distress in patients with metastatic breast cancer.
Abstract: Background Metastatic breast cancer carries with it considerable psychosocial morbidity. Studies have shown that some patients with metastatic breast cancer experience clinically significant anxiety and depression and traumatic stress symptoms. Supportive-expressive group psychotherapy was developed to help patients with cancer face and adjust to their existential concerns, express and manage disease-related emotions, increase social support, enhance relationships with family and physicians, and improve symptom control. Methods Of 125 women with metastatic breast cancer recruited into the study, 64 were randomized to the intervention and 61 to the control condition. Intervention women were offered 1 year of weekly supportive-expressive group therapy and educational materials. Control women received educational materials only. Participants were assessed at baseline and every 4 months during the first year. Data at baseline and from at least 1 assessment were collected from 102 participants during this 12-month period, and these participants compose the study population. Results Primary analyses based on all available data indicated that participants in the treatment condition showed a significantly greater decline in traumatic stress symptoms on the Impact of Event Scale (effect size, 0.25) compared with the control condition, but there was no difference in Profile of Mood States total mood disturbance. However, when the final assessment occurring within a year of death was removed, a secondary analysis showed a significantly greater decline in total mood disturbance (effect size, 0.25) and traumatic stress symptoms (effect size, 0.33) for the treatment condition compared with the control condition. Conclusion Supportive-expressive therapy, with its emphasis on providing support and helping patients face and deal with their disease-related stress, can help reduce distress in patients with metastatic breast cancer.
