Abstract
A growing number of studies indicate that chronic stress can accelerate tumor growth due to sustained sympathetic nervous system activation. Our recent findings suggest that chronic stress is associated with increased IL8 levels. Here, we examined the molecular and biological significance of IL8 in stress-induced tumor growth. Norepinephrine (NE) treatment of ovarian cancer cells resulted in a 250-300% increase in IL8 protein and 240-320% increase in its mRNA levels. Epinephrine treatment resulted in similar increases. Moreover, NE treatment resulted in a 3.5-4-fold increase in IL8 promoter activity. These effects were blocked by propranolol. Promoter deletion analyses suggested that AP1 transcription factors might mediate catecholamine-stimulated up-regulation of IL8. siRNA inhibition studies identified FosB as the pivotal component responsible for IL8 regulation by NE. In vivo chronic stress resulted in increased tumor growth (by 221 and 235%; p < 0.01) in orthotopic xenograft models involving SKOV3ip1 and HeyA8 ovarian carcinoma cells. This enhanced tumor growth was completely blocked by IL8 or FosB gene silencing using 1,2-dioleoyl-sn-glycero-3-phosphatidylcholine nanoliposomes. IL8 and FosB silencing reduced microvessel density (based on CD31 staining) by 2.5- and 3.5-fold, respectively (p < 0.001). Our findings indicate that neurobehavioral stress leads to FosB-driven increases in IL8, which is associated with increased tumor growth and metastases. These findings may have implications for ovarian cancer management.

Abstract
In the genomic era of cancer research, the development of metastases has been attributed to mutations in the tumor that enable the cells to migrate. However, gene analyses revealed that primary tumors and metastases were in some cases genetically identical and the question was raised whether metastasis formation might be an inherent feature of certain tumor cells. In contradiction to this view, the last decade of cancer research has brought to light, that tumor cell migration, similar to leukocyte and fibroblast migration, is a highly regulated process. The nervous system plays an important role in this regulation, at least in two respects: firstly, neurotransmitters are known to regulate the migratory activity of tumor cells, and secondly, nerve fibers are used as routes for perineural invasion. We also summarize here the current knowledge on the innervation of tumors. Such a process might establish a neuro-neoplastic synapse, with the close interaction of tumor cells and nerve cells supporting metastasis formation.

Abstract
Despite known advantages, the use of biobehavioral approaches in nursing research remains limited. The purposes of this article are to (1) present applications of stress and inflammation in various health conditions as examples of biobehavioral concepts and (2) stimulate similar applications of biobehavioral concepts in future nursing research. Under a biobehavioral conceptual framework, studies on stress and selective inflammatory biomarkers in cardiovascular, cancer, and pulmonary health are reviewed and summarized. Inflammation underlies many diseases, and stress is a significant source of increased inflammation. Biobehavioral concepts of stress and inflammation are highly relevant to nursing research concerned with health-related issues. Diverse biobehavioral concepts are readily applicable and should be utilized in nursing research with children and adults. To stimulate further biobehavioral research, more training and resources for nurse scientists, more unified conceptual definitions and biobehavioral conceptual frameworks, rigorous and expanded methodologies, and more collaboration are essential.

Abstract
An emerging literature attests to the ability of psychological stress to alter the inflammatory cytokine environment of the body. While the ability of stress to cause cytokine release is well established, the neural pathways involved in this control have yet to be identified. This study tests the hypothesis that IL-6 neurons of the hypothalamo-neurohypophyseal system (HNS), a neural pathway proposed to secrete IL-6 into the circulation, are activated in response to psychological stress. Colocalization studies confirm robust expression of IL-6 in cell bodies and fibers of vasopressin (but not oxytocin) neurons of the paraventricular (PVN) and supraoptic nucleus (SON) of the rat hypothalamus. In response to restraint, there was a greater increase in c-Fos expression in SON IL-6-positive (IL-6+) neurons. In addition, both psychogenic (restraint) or systemic stress (hypoxia) lead to phosphorylated ERK induction only in IL-6+ magnocellular neurons, indicating selective activation of the MAPK signaling pathway in the IL-6 subset of magnocellular neurons. Finally, restraint upregulated IL-6 mRNA expression in both the PVN and SON, which was accompanied by a four-fold increase in circulating IL-6. The data indicate that noninflammatory stressors selectively activate IL-6 magnocellular neurons, upregulate IL-6 gene expression in the PVN and SON, and increase plasma IL-6. In summary, results show that IL-6 neurons of the HNS are a recruited component of the response to psychological stress.

Psychological factors in immunomodulation induced by cancer surgery: a review. Biol Psychol 2010; 85:1-13.

Abstract
The immune system's efficacy in detecting and destroying cancer cells varies considerably throughout the stages of cancer development and its role may be critical particularly during the surgical period. Although surgery causes tumor cells to shed into the blood, immune cells have the capacity to destroy these tumor cells. However, surgery also suppresses cytotoxic capacity. It is particularly during this surgical period that psychological factors can have a significant dampening or strengthening impact on surgery-related immunomodulation response, thus exerting an effect on survival. This review describes the immune changes during the peri-surgical period and the influences psychological factors have on immune function, including the immune effects caused by psychological interventions in cancer patients. We recommend that future studies exploring the role of psychological factors on immune function and survival focus more on their influence during the peri-surgical period.

Abstract
BACKGROUND In recent years, investigators have focused increased attention on positive psychology constructs and their associations with health outcomes, such as morbidity, mortality, and adaptation to illness. The database regarding some of these concepts and models has grown appreciably, but work in this area has been subject to controversy. PURPOSE This special series of papers offers contrasting perspectives regarding research on positive psychology and health. Both proponents and critics were invited to review recent developments concerning a number of positive constructs that have been evaluated in the oncology literature and in health research, more generally. METHODS Papers are presented in the format of a debate. Significant advances are reviewed by one set of investigators, Drs, Lisa G. Aspinwall and Richard G. Tedeschi, while shortcomings and concerns are highlighted by another set of investigators, Drs. James C. Coyne and Howard Tennen. Each of these review papers is followed by a rebuttal by the opposing side. A commentary on the exchange is provided by Dr. Sherri Sheinfeld Gorin. RESULTS These papers address a range of important considerations regarding conceptualization of constructs, methodological rigor, dissemination of findings, and implications for practice. CONCLUSION The critiques and recommendations offered in these papers may help inform future efforts in this area, as the field continues to evolve.

A meta-analysis of cytokines in major depression. Biol Psychiatry 2010; 67:446-57.

Abstract
BACKGROUND Major depression occurs in 4.4% to 20% of the general population. Studies suggest that major depression is accompanied by immune dysregulation and activation of the inflammatory response system (IRS). Our objective was to quantitatively summarize the data on concentrations of specific cytokines in patients diagnosed with a major depressive episode and controls. METHODS We performed a meta-analysis of studies measuring cytokine concentration in patients with major depression, with a database search of the English literature (to August 2009) and a manual search of references. RESULTS Twenty-four studies involving unstimulated measurements of cytokines in patients meeting DSM criteria for major depression were included in the meta-analysis; 13 for tumor necrosis factor (TNF)-alpha, 9 for interleukin (IL)-1beta, 16 for IL-6, 5 for IL-4, 5 for IL-2, 4 for IL-8, 6 for IL-10, and 4 for interferon (IFN)-gamma. There were significantly higher concentrations of TNF-alpha (p < .00001), weighted mean difference (WMD) (95% confidence interval) 3.97 pg/mL (2.24 to 5.71), in depressed subjects compared with control subjects (438 depressed/350 nondepressed). Also, IL-6 concentrations were significantly higher (p < .00001) in depressed subjects compared with control subjects (492 depressed/400 nondepressed) with an overall WMD of 1.78 pg/mL (1.23 to 2.33). There were no significant differences among depressed and nondepressed subjects for the other cytokines studied. CONCLUSIONS This meta-analysis reports significantly higher concentrations of the proinflammatory cytokines TNF-alpha and IL-6 in depressed subjects compared with control subjects. While both positive and negative results have been reported in individual studies, this meta-analytic result strengthens evidence that depression is accompanied by activation of the IRS.

Abstract
Psychoneuroimmunology (PNI) is a relatively new discipline within the field of neuroscience which researches the relationship between emotional states, the central and peripheral nervous systems, and the endocrine and immune systems. Negative psychological states, such as stress, anxiety, and depression, may alter immune system regulation and modulation of peripheral cytokines. A plethora of PNI studies have shown that increased psychological stress and depression are associated with an alteration of immune functioning and worsened health outcomes for many conditions. To date, application of PNI methodology has not been reported for ocular diseases. This article provides an historical perspective on the origins of the rift between the emotional and spiritual from physical aspects of disease. A review of how stress is mediated through sympathetic adrenomedullary and hypothalamic pituitary axis activation with shifts in immunity is provided. The literature which supports spirituality in healing is presented. Finally, ocular diseases which would be most amenable to a PNI approach are discussed.

Abstract
There is growing evidence that physical health problems are caused and exacerbated by psychological factors. Research indicates that psychological distress leads to physical disease through impairment of the neuroendocrine system and its interface with the body's immune response. However, the current health care delivery system splinters care into "psychiatric" and "physical" health silos. New approaches are needed to assure adequate professional knowledge of behavioral health at basic licensure, to increase the use of advanced practice psychiatric-mental health nurses in primary care settings, to identify and teach behavioral competencies for primary care providers, and to fund the design and evaluation of integrative models of care.

Abstract
BACKGROUND The period just after surgery for breast cancer requires psychosocial adaptation and is associated with elevated distress. Distress states have been associated with decreased cellular immune functioning in this population, which could have negative effects on physical recovery. However, little is known about relations between psychological status [negative and positive mood states and overall quality of life (QOL)] and cellular signaling cytokines that could account for these associations in women undergoing treatment for breast cancer. METHODS The present study examined associations between psychological adaptation indicators (mood, QOL) and T-helper cell type 1 (Th1) cytokine production from stimulated peripheral mononuclear cells in women who had recently undergone surgery for early-stage breast cancer but had not yet begun adjuvant therapy. These associations were evaluated while controlling for relevant disease/treatment, sociodemographic, and health behavior covariates. RESULTS Lower anxiety related to greater production of the Th1 cytokine interleukin-2 (IL-2), while greater positive mood (affection) related to greater production of the Th1 cytokines IL-12 and interferon-gamma (IFN-gamma). Better QOL related to greater production of the Th1 cytokine, tumor necrosis factor-alpha (TNF-alpha). CONCLUSION Individual differences in psychosocial adaptation in women with breast cancer during the period after surgery relate to biological parameters that may be relevant for health and well-being as they move through treatment.

Abstract
Different aspects of personal relationships including social integration, social support, and social conflict have been related to inflammation. This article summarizes evidence linking the quality and quantity of relationships with gene expression, intracellular signaling mechanisms, and inflammatory biomarkers, and highlights the biological and psychological pathways through which close relationships impact inflammatory responses. Relationship conflict and lower social support can effectively modulate proinflammatory cytokine secretion both directly (via CNS/neural/endocrine/immune biobehavioral pathways), and indirectly, by promoting depression, emotional stress responses, and detrimental health behaviors. Accordingly, thorough assessments of health behaviors and attention to key methodological issues are necessary to identify the contributions of relationships to inflammation, and thus we highlight procedural issues to be considered in the design of studies. Despite some notable methodological challenges, the evidence suggests that learning more about how close relationships influence inflammation will provide important new insights into the ways that relationships impact health.

Abstract
OBJECTIVE To assess the magnitude and direction of associations of depression with C-reactive protein (CRP), interleukin (IL)-1, and IL-6 in community and clinical samples. METHODS Systematic review of articles published between January 1967 and January 2008 in the PubMed and PsycINFO electronic databases was performed. Effect sizes were calculated as stat d and meta-analyzed, using random-effects models. RESULTS Each inflammatory marker was positively associated with depression; CRP, d = 0.15 (95% CI = 0.10, 0.21), p < .001; IL-6, d = 0.25 (95% CI = 0.18, 0.31), p < .001; IL-1, d = 0.35 (95% CI = 0.03, 0.67), p = .03; IL-1ra, d = 0.25 (95% CI = 0.04, 0.46), p = .02. Associations were strongest in clinically depressed patient samples--but were also significant in community-based samples--and when clinical interviews were used. Studies adjusting for body mass index (BMI) had smaller associations, albeit significant. Relationships were inconsistent with respect to age, medication, and sex. Depression was related to CRP and IL-6 among patients with cardiac disease or cancer. CONCLUSIONS Depression and CRP, IL-1, and IL-6 are positively associated in clinical and community samples and BMI is implicated as a mediating/moderating factor. Continuity in clinic- and community-based samples suggests there is a dose-response relationship between depression and these inflammatory markers, lending strength to the contention that the cardiac (or cancer) risk conferred by depression is not exclusive to patient populations. Available evidence is consistent with three causal pathways: depression to inflammation, inflammation to depression, and bidirectional relationships.

Abstract
Motivated by previous indications that beta-adrenergic signaling can regulate tumor cell gene expression in model systems, we sought to determine whether similar dynamics occur in primary human ovarian cancer. DNA microarray analyses of 10 ovarian carcinomas identified 266 human transcripts that were differentially expressed in tumors from patients with elevated biobehavioral risk factors (high depressive symptoms and low social support) relative to grade- and stage-matched tumors from low-risk patients. Promoter-based bioinformatic analyses indicated increased activity of several beta-adrenergically-linked transcription control pathways, including CREB/ATF, NF-kappaB/Rel, STAT, and Ets family transcription factors. Consistent with increased beta-adrenergic signaling, high biobehavioral risk patients also showed increased intra-tumor concentrations of norepinephrine (but no difference in plasma norepinephrine). These data show that genome-wide transcriptional profiles are significantly altered in tumors from patients with high behavioral risk profiles, and they identify beta-adrenergic signal transduction as a likely mediator of those effects.

Abstract
Clinical and animal studies now support the notion that psychological factors such as stress, chronic depression, and lack of social support might promote tumor growth and progression. Recently, cellular and molecular studies have started to identify biological processes that could mediate such effects. This review provides a mechanistic understanding of the relationship between biological and behavioral influences in cancer and points to more comprehensive behavioral and pharmacological approaches for better patient outcomes.

Abstract
OBJECTIVE Women with gynecological cancers have reported poor health-related quality of life (QOL), with complex physical and psychological needs post-surgery and during chemotherapy treatment. There are no studies reporting interventions addressing these needs post-hospital discharge in this population. METHODS Patients were randomized into two groups. The intervention group received 6 months of specialized care by an Advanced Practice Nurse (APN); in addition, women with high distress were evaluated and monitored by a psychiatric consultation-liaison nurse (PCLN). The attention control group was assisted with symptom management by a research assistant. The effects of the 6-month intervention were evaluated using self-report questionnaires at baseline (24-48 h after surgery), 1, 3, and 6 months post- surgery. QOL assessments included the Center for Epidemiological Studies-Depression Scale , the ambiguity subscale of the Mishel Uncertainty in Illness Scale , the Symptom Distress Scale, and the Short-Form Health Survey (SF-12). The sample for the longitudinal analysis included 123 who completed QOL outcome measures across three occasions post-surgery. RESULTS The APN intervention resulted in significantly less uncertainty than the attention control intervention 6 months after surgery. When the sub-group who received the APN plus PCLN intervention was compared with the total attention control group, the sub-group had significantly less uncertainty, less symptom distress, and better SF-12 mental and physical QOL over time. CONCLUSION Nurse tailored interventions that target both physical and psychological aspects of QOL in women recovering from cancer surgery and undergoing chemotherapy produce stronger outcomes than interventions that target solely one QOL aspect.

Abstract
PURPOSE Stromal cells in the tumor microenvironment, such as macrophages, play an active role in tumor growth and angiogenesis. However, little is known about relationships of biobehavioral factors with angiogenic cytokines and matrix metalloproteinases (MMP) produced by stromal cells. This study examined distress, MMPs, and angiogenic cytokines in ovarian cancer patients and in vitro. EXPERIMENTAL DESIGN Patients suspected of ovarian cancer completed preoperative questionnaires. At surgery, 56 were confirmed to have epithelial ovarian cancer. Tumor samples were analyzed for macrophage (CD68(+)) and tumor cell levels of MMP-2, MMP-9, and vascular endothelial growth factor. In vitro stimulation of isolated macrophage cells by the stress hormones norepinephrine and cortisol was done to assess effects on MMP-9. RESULTS Depressed patients showed significant elevations of MMP-9 in CD68(+) cells, adjusting for stage (P<0.0001). Patients with higher levels of current stress (P=0.01), life stress over the last 6 months (P=0.004), and general negative affect (P=0.007) also showed significantly greater MMP-9 in CD68(+) cells. In contrast, higher social support was associated with lower levels of MMP-9 (P=0.023) and vascular endothelial growth factor (P=0.036) in tumor cells. In vitro analyses showed that macrophage MMP-9 production could be directly enhanced (up to a 2-fold increase) by the stress hormones norepinephrine and cortisol. CONCLUSIONS Ovarian cancer patients with elevated depressive symptoms, chronic stress, and low social support showed elevations in MMP-9 in tumor-associated macrophages. Direct in vitro enhancement of stromal MMP-9 production by stress hormones was also shown. These findings may have implications for patient outcomes in ovarian cancer.

Abstract
PURPOSE Inflammatory processes have been implicated in the pathogenesis of both depression and cancer. Links between depressive symptoms, interleukin-6 (IL-6), and cortisol dysregulation have been demonstrated in cancer patients, but vegetative versus affective components of depression have been minimally examined. The objective of the current study was to examine associations between IL-6, diurnal cortisol rhythms, and facets of depression in epithelial ovarian cancer patients. PATIENTS AND METHODS Patients awaiting surgery for a pelvic mass suspected for ovarian cancer completed questionnaires, collected salivary samples for 3 days presurgery, and gave a presurgical blood sample. Ascites was obtained during surgery. IL-6 was measured by enzyme-linked immunosorbent assay and cortisol by a chemiluminescence immunoassay. The final sample included 112 invasive ovarian cancer patients (86 advanced stage, 26 early stage) and 25 patients with tumors of low malignant potential (LMP). RESULTS Advanced-stage ovarian cancer patients demonstrated elevations in vegetative and affective depressive symptoms, plasma IL-6, and the cortisol area under the curve (AUC) compared with patients with LMP tumors (all P < .05). Among invasive ovarian cancer patients, greater vegetative depression was related to elevated IL-6 in plasma (P = .008) and ascites (P = .024), but affective depression was unrelated to IL-6. Elevations in total depression (P = .026) and vegetative depression (P = .005) were also related to higher evening cortisol levels. Plasma IL-6 was related to greater afternoon and evening cortisol and cortisol AUC (all P values < .005). CONCLUSION These results demonstrate significant relationships between IL-6, cortisol, and vegetative depression, and may have implications for treatment of depression in ovarian cancer patients.

Abstract
OBJECTIVES Difficulties with diagnosis and aggressive, long-term treatment may result in lower quality of life (QOL), including high levels of anxiety, depression, and uncertainty, greater symptom distress, and lower overall QOL among women with ovarian cancer. The purpose of this study was to describe demographic, clinical, and other risk factors associated with compromised QOL among women who have undergone surgery for ovarian malignancies. METHODS Subjects were recruited to participate in a clinical trial that tested a specialized nursing intervention addressing psychological and physical care among women post-surgical for ovarian cancer. QOL was measured using five standardized self-report measures: the State-Trait Anxiety Scale (SAS), the Center for Epidemiological Studies Depression Scale (CES-D), the Mishel Uncertainty in Illness Scale (MUIS), the Symptom Distress Scale (SDS), and the Short-Form Health Survey (SF-12). Baseline data were collected while women were hospitalized following surgery. RESULTS The sample (n=145) included women with ovarian cancer (58%) and other cancers metastasized to the ovaries and abdomen (42%). Mean scores on the measures were consistent with or higher than previously reported means for similar populations. Women reporting the lowest QOL were more likely to be younger, more educated, and have early stage disease. SIGNIFICANCE OF RESULTS Women who have undergone surgery for ovarian malignancies have psychological needs that are often considered secondary to physical needs. Interventions should include routine screening for distress and referral to appropriate psychological and social services, thereby facilitating quality cancer care.

Abstract
The progression of the neoplastic disease is characterized by specific alterations of energy metabolism and by symptoms like fatigue, anorexia, nausea, anaemia, immunodepression and poor performance status (PS). The main cause of these symptoms and metabolic abnormalities is the chronic action of proinflammatory cytokines released both by tumour and immune cells. The present study aimed to assess the relationship between markers of inflammation (C-Reactive Protein, Fibrinogen, proinflammatory cytokines) and energy metabolic status (BMI, leptin, oxidative stress) according to clinical parameters in 104 ovarian cancer patients at different stage and, moreover, to evaluate prospectively the changes of these parameters in accordance to tumour response in a subgroup of 70 advanced stage ovarian cancer patients. Advanced stage and poor PS were associated to high-grade inflammation and impaired energy metabolism. Among inflammatory mediators, interleukin (IL)-6 had a central role as predictive factor of leptin, reactive oxygen species and glutathione peroxidase. In turn, leptin considered the key marker of the nutritional status and energy metabolism, was independently determined from stage and IL-6, not only from BMI. Moreover, the evaluation of the changes of these parameters during the course of the neoplastic disease in the subgroup of advanced ovarian cancer patients clearly unveils the central role of IL-6 and leptin as early markers of the metabolic alterations and symptoms associated to disease progression in advanced stage ovarian cancer. Their assessment should be included in monitoring disease outcome, especially when cancer is no longer curable and quality of life becomes the primary endpoint.

Abstract
Over the past 25 years, epidemiological and clinical studies have linked psychological factors such as stress, chronic depression, and lack of social support to the incidence and progression of cancer. Although the mechanisms underlying these observations are not completely understood, recent molecular and animal studies have begun to identify specific signaling pathways that could explain the impact of neuroendocrine effects on tumor growth and metastasis. This review will highlight the importance of known clinical, molecular, and cellular processes with regard to the neuroendocrine stress effects on tumor biology and discuss possible behavioral and pharmacological interventions to ameliorate these effects and ultimately improve cancer outcomes.

Abstract
BACKGROUND Emotion regulation refers to the psychological strategies people use to cope with such stressors as hemodialysis therapy. These strategies are associated with a range of physical and psychological variation that may be related to kidney disease and its management. This study explores the associations of 2 emotion regulation strategies, reappraisal and suppression, and considers their impact on patient well-being and kidney disease management. STUDY DESIGN Cross-sectional study. SETTING AND PARTICIPANTS 106 hemodialysis patients undergoing renal replacement therapy and 94 friends or relatives. PREDICTORS Reappraisal and suppression, measured by using the Emotion Regulation Questionnaire. OUTCOMES Outcome parameters were measures of affect, psychosocial functioning, and well-being, measured using the Positive and Negative Affect Scale, the Brief COPE questionnaire, the Kidney Disease Quality-of-Life Short Form, and the Brief Symptom Inventory. RESULTS The Emotion Regulation Questionnaire measured reappraisal and suppression. Greater use of reappraisal was associated with lower levels of anxiety (r = -0.22; P = 0.03) and greater acceptance of the disease (r = 0.20; P = 0.04). It was also associated with more experience (r = 0.26; P < 0.01) and expression (r = 0.23; P = 0.02) of positive emotion and less experience (r = -0.35; P < 0.01) and expression (r = -0.29; P < 0.01) of negative emotion. Suppression was associated with less positive emotional expression (r = -0.28; P < 0.01), greater levels of depression (r = 0.22; P = 0.03) and somatization (r = 0.25; P < 0.01), and greater dissatisfaction with the time spent dealing with their kidney disease (r = -0.21; P = 0.04). Suppression also was associated with less emotional coping (r = -0.29; P < 0.01) and greater dissatisfaction with the support received from other people (r = -0.34; P < 0.01). LIMITATIONS The study focuses on emotion regulation strategies and well-being rather than clinical parameters; therefore, extensive medical data were not recorded. CONCLUSION Reappraisal has more positive clinical and psychosocial associations than suppression. The emotion regulation strategy used by hemodialysis patients has important implications for well-being and disease management.

Abstract
Patients with cancer experience a host of behavioral alterations that include depression, fatigue, sleep disturbances, and cognitive dysfunction. These behavioral comorbidities are apparent throughout the process of diagnosis and treatment for cancer and can persist well into the survivorship period. There is a rich literature describing potential consequences of behavioral comorbidities in patients with cancer including impaired quality of life, reduced treatment adherence, and increased disease-related morbidity and mortality. Medical complications of cancer and its treatment such as anemia, thyroid dysfunction, and the neurotoxicity of cancer chemotherapeutic agents account in part for these behavioral changes. Nevertheless, recent advances in the neurosciences and immunology/oncology have revealed novel insights into additional pathophysiologic mechanisms that may significantly contribute to the development of cancer-related behavioral changes. Special attention has been focused on immunologic processes, specifically activation of innate immune inflammatory responses and their regulation by neuroendocrine pathways, which, in turn, influence CNS functions including neurotransmitter metabolism, neuropeptide function, sleep-wake cycles, regional brain activity, and, ultimately, behavior. Further understanding of these immunologic influences on the brain provides a novel conceptual framework for integrating the wide spectrum of behavioral alterations that occur in cancer patients and may reveal a more focused array of translational targets for therapeutic interventions and future research. Such developments warrant complementary advances in identification of cancer patients at risk as well as those currently suffering, including an increased emphasis on the status of behavior as a "sixth vital sign" to be assessed in all cancer patients throughout their disease encounter.

Abstract
Malignant ascites is a major source of morbidity and mortality in ovarian cancer patients. It functions as a permissive reactive tumor-host microenvironment and provides sustenance for the floating tumor cells through a plethora of survival/metastasis-associated molecules. Using a syngeneic, immunocompetent model of peritoneal ovarian carcinomatosis in SP(-/-) mice, we investigated the molecular mechanisms implicated in the interplay between host secreted protein acidic and rich in cysteine (SPARC) and ascitic fluid prosurvival/prometastasis factors that result in the significantly augmented levels of vascular endothelial growth factor (VEGF) and matrix metalloproteinases (MMP). Ascitic fluid-enhanced ID8 invasiveness was mediated through VEGF via a positive feedback loop with MMP-2 and MMP-9 and through activation of alpha(v) and beta(1) integrins. Host SPARC down-regulated the VEGF-MMP axis at the transcriptional and posttranscriptional levels. In vitro, SPARC attenuated the basal as well as VEGF-induced integrin activation in tumor cells. SPARC inhibited the VEGF- and integrin-mediated ID8 proliferation in vitro and significantly suppressed their tumorigenicity in vivo. Relative to SP(+/+), SP(-/-) ascitic fluid contained significantly higher levels of bioactive lipids and exerted stronger chemotactic, proinvasive, and mitogenic effects on ID8 cells in vitro. SP(-/-) ascites also contained high levels of interleukin-6, macrophage chemoattractant protein-1, and 8-isoprostane (prostaglandin F(2)alpha) that were positively correlated with extensive infiltration of SP(-/-) ovarian tumors and ascites with macrophages. In summary, our findings strongly suggest that host SPARC normalizes the microenvironment of ovarian cancer malignant ascites through down-regulation of the VEGF-integrin-MMP axis, decreases the levels and activity of bioactive lipids, and ameliorates downstream inflammation.

Abstract
Recent studies have demonstrated that chronic stress promotes tumor growth, angiogenesis, and metastasis. In ovarian cancer, levels of the pro-angiogenic cytokine, interleukin 6 (IL-6), are known to be elevated in individuals experiencing chronic stress, but the mechanism(s) by which this cytokine is regulated and its role in tumor growth remain under investigation. Here we show that stress hormones such as norepinephrine lead to increased expression of IL-6 mRNA and protein levels in ovarian carcinoma cells. Furthermore, we demonstrate that norepinephrine stimulation activates Src tyrosine kinase and this activation is required for increased IL-6 expression. These results demonstrate that stress hormones activate signaling pathways known to be critical in ovarian tumor progression.

Abstract
Inflammation contributes to disease development, and the neuroimmunoendocrine interface is a potential site of action for inflammatory products like IL-6 to affect health. Although plasma IL-6 can stimulate the activity of the hypothalamo-pituitary-adrenocortical (HPA) axis, the precise role, if any, for IL-6 in the HPA response to nonimmunological stressors is unclear. The purpose of this study was to test the hypothesis that IL-6 in the stalk median eminence (SME) can be directly involved in stimulating ACTH secretion in response to acute stress in female swine. This study was undertaken as a result of finding IL-6 localized to the external zone of the SME next to the hypophyseal portal vessels. Results indicate that content of IL-6 in the SME decreases in response to acute stress along with an increase in nuclear phosphorylated signal transducer and activator of transcription-3 (pSTAT-3) in pituitary corticotrophs and a simultaneous increase in plasma concentrations of IL-6 and ACTH. Furthermore, we show that females concomitantly display greater SME content of IL-6 and greater HPA responsiveness to stress, thereby suggesting that IL-6 release from the SME is an integral factor contributing to enhanced stress responsiveness in females. Our results provide evidence for a direct link between IL-6 and ACTH release and reveal a sex difference in this relationship.

Abstract
Increased cytokine and neopterin levels may be responsible for cancer-related fatigue, the most common complaint among cancer patients. We quantitatively reviewed empirical findings on this topic, focusing on studies not using immunotherapy. PubMed, PsychINFO and BIOSIS were searched for articles published until July 2006. Studies remained unweighted or were weighted according to study quality and sample size. The correlation coefficient r was used for statistical analyses. Heterogeneity among the studies was examined using the I(2) index. Eighteen studies (1037 participants) of moderately high methodological quality were located and statistically analyzed. Most studies measured more than one inflammatory marker, resulting in a total of 58 correlation estimates. In 31 of these, we had to input a null correlation because results had been simply reported as nonsignificant and no further statistical information was available. General analyses based on weighting according to sample size showed a significantly positive correlation between fatigue and circulating levels of inflammatory markers (r=0.11, p<0.0001). Analyses of individual inflammatory markers revealed significantly positive correlations between fatigue and IL-6 (r=0.12, p=0.004), fatigue and IL-1 ra (r=0.24, p=0.0005), and fatigue and neopterin (r=0.22, p=0.0001). Fatigue did not correlate significantly with IL-1 beta (r=0.05, p=0.42) or TNF-alpha (r=0.04, p=0.34). Given its preliminary nature due to the limited available data, this quantitative review showed a positive association between cancer-related fatigue and circulating levels of IL-6, IL-1 ra and neopterin. Future studies examining the relationship between cancer related fatigue and inflammation would benefit from multiple rather than single blood sampling and from repeated daily ratings of the multidimensional nature of fatigue.

Abstract
The interplay between peritoneal mesothelial cells and ovarian cancer cells is critical for the initiation and peritoneal dissemination of, and ascites formation in, ovarian cancer. The production of lysophosphatidic acid (LPA) by both peritoneal mesothelial cells and ovarian cancer cells has been shown to promote metastatic phenotype in ovarian cancer. Herein, we report that exogenous addition or ectopic overexpression of the matricellular protein SPARC (secreted protein acidic and rich in cysteine) significantly attenuated LPA-induced proliferation, chemotaxis, and invasion in both highly metastatic SKOV3 and less metastatic OVCAR3 ovarian cancer cell lines. SPARC appears to modulate these functions, at least in part, through the regulation of LPA receptor levels and the attenuation of extracellular signal-regulated kinase (ERK) 1/2 and protein kinase B/AKT signaling. Moreover, our results show that SPARC not only significantly inhibited both basal and LPA-induced interleukin (IL) 6 production in both cell lines but also attenuated IL-6-induced mitogenic, chemotactic, and proinvasive effects, in part, through significant suppression of ERK1/2 and, to a lesser extent, of signal transducers and activators of transcription 3 signaling pathways. Our results strongly suggest that SPARC exerts a dual inhibitory effect on LPA-induced mesothelial-ovarian cancer cell crosstalk through the regulation of both LPA-induced IL-6 production and function. Taken together, our findings underscore the use of SPARC as a potential therapeutic candidate in peritoneal ovarian carcinomatosis.

Abstract
Cancer patients experience several stressors and emotional upheavals. Fear of death, interruption of life plans, changes in body image and self-esteem, changes in social role and lifestyle are all important issues to be faced. Moreover, Depressive Disorders may impact the course of the disease and compliance. The cost and prevalence, the impairment caused, and the diagnostic and therapeutic uncertainty surrounding depressive symptoms among cancer patients make these conditions a priority for research. In this article we discuss recent data, focusing on detection of Depressive Disorders, biological correlates, treatments and unmet needs of depressed cancer patients.

Abstract
BACKGROUND Inflammation and perturbation of the hypothalamic-pituitary-adrenal (HPA) axis function appears to play a putative role in the etiology of depression. Patients with metastatic cancer demonstrate elevated prevalence rates for depression. The objective of the current study was to illustrate the efficacy of interleukin-6 (IL-6) and HPA axis function as adjuncts to support the diagnosis of depression in cancer patients. METHODS Plasma concentrations of IL-6 and cortisol were measured in 114 cancer patients with and without depression. The relative diurnal variation of cortisol (cortisol VAR), expressed as a percentage, was calculated. Receiver operating characteristics analysis was performed. RESULTS Depression was associated with increased plasma concentrations of IL-6 (18.7 pg/mL vs. 2.7 pg/mL; P < .001) and higher cortisol concentrations at 8 AM and 8 PM. The relative cortisol VAR (11.7% vs. 60.6%, respectively; P < .001) was found to be decreased in cancer patients with depression, indicating a disturbed circadian function of the HPA axis. As a biomarker of depression, IL-6 yielded at a cutoff value of 10.6 pg/mL, a sensitivity of 79%, and a specificity of 87% (area under the curve [AUC] = 0.86; 95% confidence interval [95% CI], 0.78-0.94), whereas cortisol VAR demonstrated a sensitivity of 81% and a specificity of 88% (AUC = 0.85; 95% CI, 0.74-0.97) at a cutoff value of 33.5%. CONCLUSIONS Depression is associated with increased plasma IL-6 concentrations in patients with cancer. These patients demonstrate a dysfunction of the HPA-axis, characterized by a decreased diurnal variation of cortisol. The high sensitivity and specificity of these parameters biomarkers of depression make IL-6 and cortisol VAR helpful tools in the diagnosis of depression in patients with cancer.

Abstract
Stress can alter immunological, neurochemical and endocrinological functions, but its role in cancer progression is not well understood. Here, we show that chronic behavioral stress results in higher levels of tissue catecholamines, greater tumor burden and more invasive growth of ovarian carcinoma cells in an orthotopic mouse model. These effects are mediated primarily through activation of the tumor cell cyclic AMP (cAMP)-protein kinase A (PKA) signaling pathway by the beta(2) adrenergic receptor (encoded by ADRB2). Tumors in stressed animals showed markedly increased vascularization and enhanced expression of VEGF, MMP2 and MMP9, and we found that angiogenic processes mediated the effects of stress on tumor growth in vivo. These data identify beta-adrenergic activation of the cAMP-PKA signaling pathway as a major mechanism by which behavioral stress can enhance tumor angiogenesis in vivo and thereby promote malignant cell growth. These data also suggest that blocking ADRB-mediated angiogenesis could have therapeutic implications for the management of ovarian cancer.

Abstract
Social support has been reliably related to lower rates of morbidity and mortality. An important issue concerns the physiological mechanisms by which support influences such health endpoints. In this review, I examine evidence linking social support to changes in cardiovascular, neuroendocrine, and immune function. Consistent with epidemiological evidence, social support appears to be related to more positive "biological profiles" across these disease-relevant systems. Recent research on immune-mediated inflammatory processes is also starting to provide data on more integrative physiological mechanisms potentially linking social support to health. The implications of these links, along with future research directions are discussed.

Abstract
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.
