Abstract
OBJECTIVE The sustainment of gains for cancer patients provided psychosocial interventions is unclear. Furthermore, it is unknown whether interventions also yield long-term positive changes. The present study experimentally tests if an intervention delivered at cancer diagnosis could yield broad, long-term, changes in domains such as relationships, worldview, priorities, and goals. It was hypothesized that the intervention group would report more positive and fewer negative life changes during survivorship versus the control group. METHOD Patients with Stage II/III breast cancer were randomized to biobehavioral intervention (BBI) or assessment only. At randomization, patients completed measures of cancer stress (Impact of Events Scale [IES]) and depressive symptoms (Center for Epidemiological Studies Depression scale [CES-D]). At the 24-month follow-up, survivors (N = 160) completed a thought listing task with 7 prompts (e.g., "relationships"). Patients listed thoughts about change since diagnosis and rated each for valence. Groups were compared on the frequency of positive/negative thoughts across prompts. Listed thoughts were content analyzed. RESULTS BBI survivors reported significantly more positive changes (p < .05), controlling for IES and CES-D. Groups did not differ on negative changes. Patients with higher IES/CES-D scores reported more negative changes at 24 months (ps < .05). Content analysis revealed a predominance (13/23) of positive thought categories. CONCLUSIONS Adding support for efficacy, BBI survivors reported significantly more positive life changes since diagnosis than survivors not receiving BBI. More generally, heightened stress/depressive symptoms at diagnosis foretold survivors' reporting of more negative changes. Thought listing is a strategy to obtain personalized accounts of life changes after breast cancer. (PsycINFO Database Record (c) 2019 APA, all rights reserved).

Abstract
Many breast cancer survivors have to deal with a variety of psychological and physiological sequelae including impaired immune responses. The primary purpose of this randomized controlled trial was to determine the efficacy of a mindfulness‐based stress reduction (MBSR) intervention for mood disorders in women with breast cancer. Secondary outcomes were symptom experience, health status, coping capacity, mindfulness, posttraumatic growth, and immune status. This RTC assigned 166 women with breast cancer to one of three groups: MBSR (8 weekly group sessions of MBSR), active controls (self‐instructing MBSR) and non‐MBSR. The primary outcome measure was the Hospital Anxiety and Depression Scale. Secondary outcome measures were: Memorial Symptom Assessment Scale, SF‐36, Sense of Coherence, Five Facets of Mindfulness Questionnaire, and Posttraumatic Growth Index. Blood samples were analyzed using flow cytometry for NK‐cell activity (FANKIA) and lymphocyte phenotyping; concentrations of cytokines were determined in sera using commercial high sensitivity IL‐6 and IL‐8 ELISA (enzyme‐linked immunosorbent assay) kits. Results provide evidence for beneficial effects of MBSR on psychological and biological responses. Women in the MBSR group experienced significant improvements in depression scores, with a mean pre‐MBSR HAD‐score of 4.3 and post‐MBSR score of 3.3 (P = 0.001), and compared to non‐MBSR (P = 0.015). Significant improvements on scores for distress, symptom burden, and mental health were also observed. Furthermore, MBSR facilitated coping capacity as well as mindfulness and posttraumatic growth. Significant benefits in immune response within the MBSR group and between groups were observed. MBSR have potential for alleviating depression, symptom experience, and for enhancing coping capacity, mindfulness and posttraumatic growth, which may improve breast cancer survivorship. MBSR also led to beneficial effect on immune function; the clinical implications of this finding merit further research.

Abstract
PURPOSE Five-year disease endpoint trajectories are available for every cancer site. In contrast, there are few longitudinal, biobehavioral studies of survivors extending beyond the first or second year following diagnosis. This gap is addressed with stress, depressive symptom, and immunity data from breast cancer patients followed continuously for 5 years. EXPERIMENTAL DESIGN Women (N = 113) diagnosed and surgically treated for breast cancer and awaiting adjuvant therapy completed self-report measures of stress and depressive symptoms and provided blood for immune assays [natural killer cell cytotoxicity (NKCC) and T-cell blastogenesis]. Assessments (N = 12) were repeated every 4 to 6 months for 5 years. RESULTS Multiphase linear mixed models show phases of change and identified specific time points of change. Cancer stress shows two distinct phases of decline, with the change point being 12 months. In contrast, a steep decline in depressive symptoms occurs by 7 months, with stable, low levels thereafter. NKCC shows a steady upward trajectory through 18 months and upper limit stability thereafter, whereas there was no reliable trajectory for T-cell blastogenesis. CONCLUSIONS For the first time, trajectories and specific time points of change in biobehavioral data for breast cancer survivors are provided, traced through 5 years. Following diagnosis, the breast survivor experience is one of a co-occurrence of change (recovery) in psychologic and innate immunity markers from diagnosis to18 months, and a pattern of stability (depression, NKCC) or continued improvement (stress) through year 5. These data provide new directions for survivorship care and detail of the biobehavioral trajectory. Clin Cancer Res; 23(1); 52-61. ©2016 AACR.

Abstract
BACKGROUND Chemotherapy-induced immune suppression has mainly been studied in patients with advanced cancer, but the influence of chemotherapy on the immune system in early stage cancer patients has so far not been studied systematically. The aim of the present study was to monitor the immune system during anthracycline- and taxane-based adjuvant chemotherapy in early stage breast cancer patients, to assess the impact of circulating tumor cells on selected immune parameters and to reveal putative angiogenic effects of circulating endothelial cells. METHODS Peripheral blood samples from 20 early stage breast cancer patients were analyzed using a flow cytometric multi-color of antibodies to enumerate lymphocyte and dendritic cell subsets, as well as endothelial and tumor cells. An enzyme-linked immunosorbent assay (ELISA) was used to measure the levels of various serological factors. RESULTS During chemotherapy, all immunological parameters and angiogenesis surrogate biomarkers showed significant decreases. The numbers of circulating tumor cells showed significant inverse correlations with the numbers of T helper cells, a lymphocyte subset directly related to effective anti-tumor responses. Reduced T helper cell numbers may contribute to systemic immunosuppression and, as such, the activation of dormant tumor cells. CONCLUSIONS From our results we conclude that adjuvant chemotherapy suppresses immune function in early stage breast cancer patients. In addition, we conclude that the presence of circulating tumor cells, defined as pan-cytokeratin(+), CD326(+), CD45(-) cells, may serve as an important indicator of a patient's immune status. Further investigations are needed to firmly define circulating tumor cells as a predictor for the success of breast cancer adjuvant chemotherapy.

Abstract
Introduction Many women experience emotional distress, depression and anxiety after a diagnosis of breast cancer. Psychological stress and depression have been associated with hypothalamic-pituitary-adrenal (HPA) axis dysregulation that may adversely affect immune system functioning and impact upon survival. This study investigated the effects of a lifestyle intervention on indices of psychological health status, HPA axis regulation and immune function in overweight women recovering from early-stage breast cancer treatment. Methods A total of 85 women treated for breast cancer 3 to 18 months previously were randomly allocated to a 6-month exercise and hypocaloric healthy eating program plus usual care or usual care alone (control group). Women in the intervention group received three supervised exercise sessions per week and individualized dietary advice, supplemented by weekly nutrition seminars. Depressive symptoms (Beck Depression Inventory version II: BDI-II), perceived stress (Perceived Stress Scale: PSS), salivary diurnal cortisol rhythms; inflammatory cytokines (IL-6 and Tumor necrosis factor-α), leukocyte phenotype counts, natural killer (NK) cell cytotoxicity and lymphocyte proliferation following mitogenic stimulation were assessed at baseline and 6-month follow up. Results Compared with the control group, the intervention group exhibited a reduction in depressive symptoms (adjusted mean difference, 95% confidence intervals (95% CI): −3.12, −1.03 to −5.26; P = 0.004) at the 6-month follow-up but no significant decrease in PSS scores (−2.07, −4.96 to 0.82; P = 0.16). The lifestyle intervention also had a significant impact on diurnal salivary cortisol rhythm compared with usual care alone, as evidenced by an increase in morning salivary cortisol at the 6-month follow-up (P <0.04), indicating a change in HPA axis regulation. Women in the control group had higher total leukocyte, neutrophil and lymphocyte counts in comparison to the intervention group at the 6-month follow-up (P ≤0.05), whereas there was no difference in NK cell counts (P = 0.46), NK cell cytotoxicity (P = 0.85) or lymphocyte proliferation responses (P = 0.11) between the two groups. Conclusion Our results show that the lifestyle intervention resulted in a reduction in depressive symptoms and a normalisation of HPA axis regulation. Such changes could have important implications for long-term survival in women recovering from early-breast cancer treatment. Trial registration Current Controlled Trials: ISRCTN08045231

Abstract
Background The stress of a breast cancer diagnosis and its treatment can produce a variety of psychosocial sequelae including impaired immune responses. Mindfulness Based Stress Reduction (MBSR) is a structured complementary program that incorporates meditation, yoga and mind-body exercises. Despite promising empirical evidence for the efficacy of MBSR, there is a need for randomized controlled trials (RCT). There is also a need for RCTs investigating the efficacy of psychosocial interventions on mood disorder and immune response in women with breast cancer. Therefore, the overall aim is to determine the efficacy of a Mindfulness Based Stress Reduction (MBSR) intervention on well-being and immune response in women with breast cancer. Methods and design In this RCT, patients diagnosed with breast cancer, will consecutively be recruited to participate. Participants will be randomized into one of three groups: MBSR Intervention I (weekly group sessions + self-instructing program), MBSR Intervention II (self-instructing program), and Controls (non-MBSR). Data will be collected before start of intervention, and 3, 6, and 12 months and thereafter yearly up to 5 years. This study may contribute to evidence-based knowledge concerning the efficacy of MBSR to support patient empowerment to regain health in breast cancer disease. Discussion The present study may contribute to evidence-based knowledge concerning the efficacy of mindfulness training to support patient empowerment to regain health in a breast cancer disease. If MBSR is effective for symptom relief and quality of life, the method will have significant clinical relevance that may generate standard of care for patients with breast cancer.

Abstract
Background Cell proliferation is associated with the pathogenesis of cancer because it provides opportunities for accumulating genetic mutations. However, biomarkers of cell proliferation in response to environmental stimuli have not been adequately explored for breast cancer risk. Methods In a case-control study of 200 breast cancer patients and 360 healthy controls, we investigated the association between phytohemagglutinin (PHA)-induced mitotic index in blood lymphocyte and breast cancer risk. Results Having high mitotic index (>3.19%) was associated with an increased risk of breast cancer, with adjusted odds ratios (95% confidence interval) of 1.54 (1.03–2.30) and 2.03 (1.18–3.57) for all women and post-menopausal women, respectively. Mitotic index was correlated with some reproductive factors and body mass index in controls. Conclusions Our data suggest increased PHA-induced mitotic index in blood lymphocytes is associated with an increased breast cancer risk and that this association may be modulated by reproductive and other hormones.

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
We present a method for the comparative analysis of parameter groups according to their correlation to disease. The theoretical basis of the proposed method is Information Theory and Nonparametric Statistics. Normalized mutual information is used as the measure of correlation between parameters, and statistical conclusions are based on ranking. The fluorescence polarization (FP) parameter is considered as the principal diagnostic characteristic. The FP was measured in fluorescein diacetate (FDA)-stained individual peripheral blood mononuclear cells (PBMC), derived from healthy subjects and breast cancer (BC) patients, under different stimulation conditions: by tumor tissue, the mitogen phytohemagglutinin (PHA) or without the stimulants. The FP parameters were grouped according to their correlation with breast cancer. It was established that the greatest difference between cells of BC patients and healthy subjects is found in the PHA test (parameter P1).

Abstract
Genetic variations in cell cycle checkpoints and DNA repair genes are associated with prolonged cell cycle G(2) delay following ionizing radiation (IR) treatment and breast cancer risk. However, different studies reported conflicting results examining the association between post-IR cell cycle delay and breast cancer risk utilizing four different parameters: cell cycle G(2) delay index, %G(2)-M, G(2)/G(0)-G(1), and (G(2)/G(0)-G(1))/S. Therefore, we evaluated whether different parameters may influence study results using a data set from 118 breast cancer cases and 225 controls as well as lymphoblastoid and breast cancer cell lines with different genetic defects. Our results suggest that cell cycle G(2) delay index may serve as the best parameter in assessing breast cancer risk, genetic regulation of IR-sensitivity, and mutations of ataxia telangiectasia mutated (ATM) and TP53. Cell cycle delay in 21 lymphoblastoid cell lines derived from BRCA1 mutation carriers was not different from that in controls. We also showed that IR-induced DNA-damage signaling, as measured by phosphorylation of H2AX on serine 139 (γ-H2AX) was inversely associated with cell cycle G(2) delay index. In summary, the cellular responses to IR are extremely complex; mutations or genetic variations in DNA damage signaling, cell cycle checkpoints, and DNA repair contribute to cell cycle G(2) delay and breast cancer risk. The cell cycle G(2) delay assay characterized in this study may help identify subpopulations with elevated risk of breast cancer or susceptibility to adverse effects in normal tissue following radiotherapy.

Abstract
BACKGROUND Although immunosuppression from cancer adjuvant therapy has been documented, how these suppressed immune responses recover to baseline values after completion of cancer adjuvant therapy has not been studied systematically. OBJECTIVES The objective of this study was to examine the probability of immune recovery after cancer adjuvant therapy and the potential impact of cancer adjuvant therapy type and cancer stage on immune recovery in patients with newly diagnosed breast cancer. METHODS In a repeated-measures design, immune responses were measured four times in 80 patients with early-stage breast cancer: before and at 2, 6, and 12 months from the beginning of cancer adjuvant therapy. Natural killer cell activity, lymphokine-activated killer cell activity, lymphocyte proliferation, CD subsets (CD4, CD8, and CD56), and cytokines (interferon-gamma, interleukin [IL]-2, IL-4, IL-6, and IL-1alpha) were selected for their relevance to breast cancer. Immune recovery was defined by the level of immune response reaching to and above baseline levels. Data were analyzed using a multivariate generalized linear mixed-model approach. RESULTS Delayed immune recovery to pretreatment baseline levels continued to the 12-month time point in all parameters. The percentages of immune recovery ranged from 6% to 76% of the patients, varying among immune parameters. Overall, immune recovery was poorer for interferon-gamma, IL-2, IL-4, lymphocyte proliferation, and natural killer cell activity than was for CD subsets and IL-6. The type of cancer adjuvant therapy, not cancer stage, showed selective influence on immune recovery. Chemotherapy or chemotherapy and radiotherapy combination significantly delayed IL-2 recovery, whereas radiotherapy significantly delayed IL-4 recovery. DISCUSSION Immune recovery after breast cancer adjuvant therapy is delayed significantly for an extended time period in numerous immune parameters. The type of cancer adjuvant therapy has selective influence on immune recovery. Future investigations are warranted to elucidate the time course of immune recovery, clinical significance of poor immune recovery, and factors influencing immune recovery to develop potential interventions.

Abstract
Breast cancer is a common cancer among American women. The diagnosis, treatment, and the challenges of survivorship all have potential to increase women's levels of distress to levels that might influence their adaptation and possibly the course of their disease. Psychological distress can influence tumor progression via many different pathways (e.g., genetic changes, immune surveillance, pro-angiogenic processes). Psychological intervention has been shown to facilitate psychological adaptation to breast cancer. But can psychological intervention influence cancer relevant biological outcomes among breast cancer survivors? We review the literature on how psychological intervention can influence cancer relevant biological outcomes among breast cancer patients. We limited the present review to randomized controlled trials reported in the past 6 years that tested the effects of psychological intervention on biological dependent variables among patients with non-metastatic breast cancer. There are data to suggest that psychological intervention can influence neuroendocrine (e.g., cortisol) and immune function indicators, especially lymphocyte proliferation and TH1 cytokine production. Future psychological intervention studies should also focus on more newly discovered stress-tumor pathways (e.g., neuroendocrine processes promoting tumor growth and metastasis) and follow larger cohorts of the more vulnerable patients over longer periods to evaluate the biobehavioral mechanisms and lasting effects of these interventions on health and quality of life.

Abstract
BACKGROUND A period of tumor growth precedes the clinical detection of breast cancer recurrence. We explore immune, endocrine, and behavioral parameters during this period. METHODS We conducted a phase III clinical trial in which women with surgically treated stage II/III breast cancer (N = 227) were randomized to receive a psychological intervention or assessment-only and then regularly assessed for 10 years. Patients who recurred (R, n = 48) were matched with patients remaining disease-free (DF, n = 48) on demographic and prognostic characteristics, treatment, and duration of disease-free follow-up. Data at three assessment points, occurring, on average, 17, 11, and 4 months before the recurrence was detected clinically, with equivalent time points for the disease-free group, were examined. Mixed-effects models tested for group differences in immune cell counts and function as well as endocrine and behavioral parameters. RESULTS In the 17 months prior to recurrence detection, patients exhibited higher white blood cell count, neutrophil, lymphocyte, and natural killer cell counts, relative to DF patients. R patients also showed higher cortisol, worse physical functioning, fatigue, and quality of life. Follow-up analyses showed patients with local recurrences to differ from those with distant recurrence, with the former exhibiting elevated natural killer cell cytotoxicity, lymphocyte proliferative response, fatigue, pain, and emotional distress (depression, anxiety), and the latter exhibiting higher neutrophil, lymphocyte, and natural killer cell counts. CONCLUSION Patients who would recur showed reliable biobehavioral alterations more than a year prior to their diagnosis. This novel observation may contribute to our understanding of the disease relapse processes.

Abstract
PURPOSE/OBJECTIVES To summarize the findings of objective and subjective breast cancer risk assessments and their association with psychological distress and immune responses in healthy women with a family history of breast cancer. DATA SOURCES Published articles and book chapters. DATA SYNTHESIS Healthy women with a family history of breast cancer have shown decreased immune responses (i.e., low natural killer cell activity and low Th1 cytokine production), exaggerated biophysiologic reactivity to stimuli, and increased psychological distress. CONCLUSIONS Objective and subjective breast cancer risk is associated with impaired immune responses and exaggerated biophysiologic responses in healthy women with a family history of breast cancer. Increased psychological distress can contribute further to negative immune responses. Additional studies are warranted to substantiate and extend the findings based on more comprehensive assessments of objective and subjective breast cancer risk. IMPLICATIONS FOR NURSING Biophysiologic assessment is a useful approach for nurses in early identification of women at risk for breast cancer and developing appropriate strategies to reduce the risk.

Abstract
BACKGROUND Breast cancer survivors often encounter physiological and psychological problems related to their diagnosis and treatment that can influence long-term prognosis. The aim of this research is to investigate the effects of a lifestyle intervention on body weight and psychological well-being in women recovering from breast cancer treatment, and to determine the relationship between changes in these variables and biomarkers associated with disease recurrence and survival. METHODS/DESIGN Following ethical approval, a total of 100 patients will be randomly assigned to a lifestyle intervention (incorporating dietary energy restriction in conjunction with aerobic exercise training) or normal care control group. Patients randomised to the dietary and exercise intervention will be given individualised healthy eating dietary advice and written information and attend moderate intensity aerobic exercise sessions on three to five days per week for a period of 24 weeks. The aim of this strategy is to induce a steady weight loss of up to 0.5 Kg each week. In addition, the overall quality of the diet will be examined with a view to (i) reducing the dietary intake of fat to approximately 25% of the total calories, (ii) eating at least 5 portions of fruit and vegetables a day, (iii) increasing the intake of fibre and reducing refined carbohydrates, and (iv) taking moderate amounts of alcohol. Outcome measures will include body weight and body composition, psychological health status (stress and depression), cardiorespiratory fitness and quality of life. In addition, biomarkers associated with disease recurrence, including stress hormones, estrogen status, inflammatory markers and indices of innate and adaptive immune function will be monitored. DISCUSSION This research will provide valuable information on the effectiveness of a practical, easily implemented lifestyle intervention for evoking positive effects on body weight and psychological well-being, two important factors that can influence long-term prognosis in breast cancer survivors. However, the added value of the study is that it will also evaluate the effects of the lifestyle intervention on a range of biomarkers associated with disease recurrence and survival. Considered together, the results should improve our understanding of the potential role that lifestyle-modifiable factors could play in saving or prolonging lives.

Abstract
Cytokines produced by T lymphocytes are critical to the efficacy of a given immune response and dysregulation of immune responses may play a role in cancer progression. We assessed the intracellular cytokine profiles of T cells in the peripheral blood of women with breast cancer and explored the relationship of these responses with the presence of cancer in lymph nodes and bone marrow. Peripheral blood lymphocytes from 84 patients and 26 healthy volunteers were analyzed by 4-color flow cytometry for surface markers and for intracellular cytokines. Bone marrow samples from some of these patients were also collected and analyzed for the presence of epithelial cells (micrometastases) by flow cytometry. The percentages of both CD4(+) and CD8(+) cells producing type1 (IL-2, IFN-gamma or TNF-alpha) and type 2 (IL-4) were significantly lower in patients with breast cancer compared to healthy controls. These results indicate a general immune dysfunction in these patients as opposed to a shift in the balance of type1 and type2 cells. These dysregulated T cell responses did not correlate with age, stage of disease, or nodal status. However, we did observe a correlation between number of micrometastases in the bone marrow and T cell responsiveness.

Abstract
INTRODUCTION Malignant diseases are known to modulate the number and function of myeloid, erythroid, and lymphoid cells. Since these cells are derived from hematopoietic stem cells (HSC), it is not clear if the observed effects of cancer on such cells are direct or indirect via stem cells. The purpose of this study was to evaluate the effect of breast cancer upon the levels and activity of peripheral blood hematopoietic stem cells. MATERIALS AND METHODS Four weeks following the establishment of 4T1 breast cancers in BALB/c mice, the animals were killed, blood and spleen harvested, and processed for light density mononuclear cells. Colony forming unit in culture assay was used to determine the activity of HSCs. Flow cytometry was used to determine the levels of lineage negative HSCs expressing c-kit and Sca-1 antigen (Lin c-kitSca-1). Mitogenic, cytotoxic and ELISPOT assays were used to evaluate functional properties of cells. Plasma cytokine levels were determined with ELISA assay. RESULTS In tumor-bearing mice, there was a 2- and 4-fold increase in the levels and proliferative capacity of HSCs, respectively, compared with controls. Contemporaneously, there was a 13-fold increase in plasma G-CSF in tumor-bearing animals compared with controls (0.225 ng/ml versus 3.0 ng/ml). Furthermore, the number of interferon gamma-secreting cells was significantly increased in tumor-bearing animals. Concurrently, cytotoxic activity of NK cells was significantly increased in tumor-bearing animals as compared with controls (22.4 +/- 10.6 versus 10.3 +/- 2.95; P < 0.05). SUMMARY These results suggest that (1) breast cancer mobilizes hematopoietic stem cells in mice presumably through G-CSF production, and (2) that such cancer-mobilized stem cells give rise to immune cell lineages which are functionally hyperactive in their cytotoxic activities. Such cells could be expected to have appreciable therapeutic benefit in terms of cancer cell cytotoxic activity when used as part of stem cell transplantation therapy in cancer patients.

Abstract
A new methodology for the detection of functional response of peripheral blood mononuclear cells against breast cancer (BC) antigens was developed. The method is based on cellular enzymatic activity measurements, using a fluorogenic substrate. We used this method to estimate the kinetic activity of lymphocytes derived from cancer patients and healthy donors. The aim of the study was to determine a possible correlation between the basic characteristics (K(m) and V(max)) of biochemical enzymatic reactions in live peripheral white mononuclear cells and common clinical-pathological characteristics in BC patients. Our method shows that the enzymatic activity, upon interaction with mitogen or tumor antigens, of the peripheral blood cells in BC patients is different from the enzymatic reactions in healthy individuals. This holds true in the early stages, and the difference persists throughout all of the stages of the disease. This difference is manifested, primarily, by an increase in the K(m) values after cell incubation with tumor tissue. It was also demonstrated that higher K(m) values of tumor tissue-activated peripheral blood mononuclear cells are associated with a better prognostic status of the BC patients (lymph node-negative tumors, hormone receptor preservation, and the absence of Her-2/neu protein overexpression). Thus, the present methodology may serve as an additional criterion for prognosis and monitoring, both in BC patients, and in individuals associated with high cancer risk.

Abstract
OBJECTIVE This study examined the effect of a cognitive-behavioral stress management (CBSM) intervention on emotional well-being and immune function among women in the months following surgery for early-stage breast cancer. METHOD Twenty-nine women were randomly assigned to receive either a 10-week CBSM intervention (n=18) or a comparison experience (n=11). The primary psychological outcome measure was benefit finding. The primary immune function outcome measure was in vitro lymphocyte proliferative response to anti CD3. RESULTS Women in the CBSM intervention reported greater perceptions of benefit from having breast cancer compared to the women in the comparison group. At 3-month follow-up, women in the CBSM group also had improved lymphocyte proliferation. Finally, increases in benefit finding after the 10-week intervention predicted increases in lymphocyte proliferation at the 3-month follow-up. CONCLUSION A CBSM intervention for women with early-stage breast cancer facilitated positive emotional responses to their breast cancer experience in parallel with later improvement in cellular immune function.

Abstract
BACKGROUND The preoperative immunological condition of patients with malignant tumors should be considered in determining the prognosis. METHODS A lymphoblastic transformation test in which lymphocytes were stimulated with phytohemagglutinin (PHA) was performed for 155 patients with esophageal squamous cell carcinoma (SCC). RESULTS Multivariate analysis demonstrated that a lower preoperative PHA response (p = 0.028), as well as the depth of the tumor (p = 0.011), lymph node metastasis (p = 0.0003), lymphatic permeation (p = 0.002), and the incidence of postoperative complication (p = 0.016) were independent factors associated with a poor prognosis for patients with SCC of the esophagus. CONCLUSIONS A suppressed PHA response is an additional significant prognosticator for SCC of the esophagus.

Abstract
Research has found suggestive links between emotional distress and immune and neuroendocrine measures in cancer patients. Furthermore, several studies have reported that participation in psychological support groups is associated with better health outcomes for cancer patients. However, controversy exists surrounding these findings, and the mechanisms behind such effects are unclear. This article integrates current evidence from several lines of research concerning the relations among coping, psychological adjustment, cortisol and immune function, and disease progression in breast cancer patients. A biopsychosocial model is evaluated in which coping and psychological adjustment are associated with alterations in cortisol levels, immune function, and potential long-term medical outcomes in breast cancer patients. Although strong evidence suggests that coping and psychosocial intervention can improve psychological outcomes for breast cancer patients, potential effects on physiological outcomes remain speculative.

Abstract
We investigated whether decreases in circulating polymorphonuclear neutrophils (PMN) during lethal Escherichia coli (E. coli) sepsis in canines are related to insufficient host granulocyte colony-stimulating factor (G-CSF). Two-year-old purpose-bred beagles had intraperitoneal E. coli-infected or -noninfected fibrin clots surgically placed. By 10 to 12 h following clot, both infected survivors and nonsurvivors had marked increases (P = 0.001) in serum G-CSF levels (mean peak G-CSF ng/ml +/- SE, 1,931 +/- 364 and 2,779 +/- 681, respectively) compared with noninfected controls (134 +/- 79), which decreased at 24 to 48 h. Despite increases in G-CSF, infected clot placement caused delayed (P = 0.06) increases in PMN (mean +/- SE change from baseline in cells x 10(3)/mm(3) at 24 and 48 h) in survivors (+3.9 +/- 3.9 and +13.8 +/- 3.6) compared with noninfected controls (+13.1 +/- 2.8 and +9.1 +/- 2.5). Furthermore, infected nonsurvivors had decreases in PMN (-1.4 +/- 1.0 and -1.1 +/- 2.3, P = 0.006 compared with the other groups). We next investigated whether administration of G-CSF immediately after clot placement and continued for 96 h to produce more rapid and prolonged high levels of G-CSF after infection would alter PMN levels. Although G-CSF caused large increases in PMN compared with control protein from 2 to 48 h following clot in noninfected controls, it caused much smaller increases in infected survivors and decreases in infected nonsurvivors (P = 0.03 for the ordered effect of G-CSF comparing the three groups). Thus insufficient host G-CSF is unlikely the cause of decreased circulating PMN in this canine model of sepsis. Other factors associated with sepsis either alone or in combination with G-CSF itself may reduce increases or cause decreases in circulating PMN.

Abstract
OBJECTIVES To investigate the impact of polychemotherapy on cellular immunity in patients with testicular cancer. METHODS Lymphocyte subpopulations, lymphoproliferative responses to mitogenic stimulation, and mitogen-induced release of soluble interleukin-2 receptor from peripheral blood mononuclear cells were investigated in 15 patients with testicular germ cell tumors a median of 61 months (range 7 to 73) after polychemotherapy with bleomycin, etoposide, and cisplatin (BEP). RESULTS The numbers of peripheral blood T cells (CD3+), CD4+ and CD8+ subsets, and lymphoproliferative responses to pokeweed mitogen, phytohemagglutinin, and concanavalin A in patients were comparable to those of healthy control subjects. When two groups of patients were formed according to elapsed time from BEP polychemotherapy and study onset (group A, 12 months and group B, 69 months after termination of BEP), a significant increase in lymphoproliferative response to concanavalin A (P <0.05) was found in group A 1 year after chemotherapy. CONCLUSIONS BEP chemotherapy administered to patients with testicular cancer does not result in impairment of cellular immunity but rather leads to a significant increase in the capacity of patients' lymphocytes to respond to mitogenic stimulation up to 1 year after polychemotherapy. Moreover, the increased T-cell activity found after BEP therapy may contribute to the high rate of long-term complete remission.

Abstract
Cell-mediated immune (CMI) responses to tumor-associated antigens (TAA) in the early postoperative period were examined for correlations with disease recurrence and survival in a 13-year-prospective study of 77 stage 1 and 2 breast cancer patients treated with modified radical or radical mastectomy alone. Among the 21 patients who had positive lymphoproliferative tests using patients' peripheral blood mononuclear cells and autologous TAA of breast cancer cells, only one died from metastatic disease (5%). Among the 56 patients who had a negative test, 23 died from metastatic disease (41%). This difference is statistically significant (p = 0.002) Three other risk factors including tumor size, nodal status and cell differentiation patterns were also analyzed. When these three clinical-pathologic criteria were analyzed individually, none reliably predicted disease recurrence and survival. Nodal status was the most predictive clinical-pathologic risk factor, but was not significant (p = 0.089). The results of this study demonstrate the detection of CMI responses against autologous TAA by lymphoproliferative assays identifies a sub-set of stage 1 and 2 breast cancer patients who are at minimal risk of developing metastatic disease. This testing also identifies immunologically unreactive patients who are at risk for disease recurrence.

Abstract
The proliferative response of lymphocytes to mitogens is known to be decreased in cancer patients; this phenomenon is thought to play an important role in disease progression, but it has not been studied as a prognostic factor in cervical cancer patients receiving treatment. Fourteen patients with advanced cervical cancer submitted to chemotherapy with cis-platinum (100 mg/m2/cycle) and bleomycin (30 mg/cycle) over three cycles every 4 weeks were evaluated. Mean follow-up time was 30 months. The following laboratory tests carried out on peripheral blood lymphocytes collected before and at the end of chemotherapy were used as prognostic factors: proliferative response of lymphocytes to phytohemagglutinin (PHA) and stimulated with interleukin 12 (IL-12), capacity of gamma interferon production (IFN-gamma), and variations in memory T cell (CD45-RO) and naive T cell (CD45-RA) subsets. A clear correlation was obtained between response to treatment, survival rates, and PHA-induced proliferative response. A significant difference was observed in the number of CD45-RO lymphocyte at the pre-chemotherapy period and IFN-gamma production at the post-chemotherapy period in the group of good responders to treatment. The use of IL-12 produced a leveling in both groups for lymphocyte proliferation, i.e., a recovery from the deficiency presented by the lymphocyte of the poor responders group. The parameters of immunologic assays, especially proliferative response, appears to be correlated with prognosis and survival rates and therefore are good discriminating factors for the selection of groups of patients that will benefit from this type of treatment. IL-12 seems to play an important role in the regulation of the antitumor immune response and should be considered for therapeutic use.

Abstract
That the inheritance of mutations in tumor susceptibility genes alone cannot determine risk for developing cancer is now well accepted. Immune functions have long been recognized as one of the important risk modifying factors in this regard. In an attempt to develop a multiparametric approach to identify high risk individuals from cancer families, we have examined NK cell function in unaffected members from familial breast cancer families. We have also carried out a parallel study of T lymphocyte functions in these individuals. Our studies demonstrate a significantly lower NK cell activity in members from cancer families. T lymphocyte activity also showed a similar trend, with the unaffected members demonstrating a notably lowered T lymphocyte function. In addition the data from patients reveals differential sensitivity of NK and T lymphocyte function to the disease phenotype. Implications of these observations are discussed.

Abstract
The human aromatase gene (P450arom) is widely expressed, albeit in a tissue-specific manner. In the present study, we measured aromatase activity and investigated the transcribed and translated products of the P450arom gene before and after Epstein-Barr virus (EBV) transformation in peripheral blood lymphocytes (PBLs) from normal individuals. Aromatase activity was determined by [3H]-delta4-androstenedione (A) to [3H]-estrone (E1) conversion. Cellular total RNA and protein lysates were subjected to RT-PCR and Western analysis, respectively. Rapid amplification of cDNA ends (RACE) was used for the detection of novel 5'-untranslated ends of the P450arom mRNA, which were subsequently sequenced and compared to the known transcripts of this gene. In untransformed PBLs, two known variants of exon 1 of the P450arom gene were expressed, corresponding to promoters PI.3 and PII, or 1c and 1d, respectively. In EBV-transformed PBLs, a cryptic splice site was revealed and a new 5'-untranslated product was found. RNase protection assay confirmed that this splice variant is not a RACE artifact. The 53 K P450arom protein was detectable in PBLs both before and after EBV transformation. We conclude that (i) the P450arom mRNA is present in human PBLs and (ii) EBV transformation of the latter leads to novel alternative splicing of the 5' end of this gene.

Abstract
Amplification and over-expression of the HER-2/neu proto-oncogene are associated with poor prognosis in women with both node-positive and node-negative breast cancer. Therefore, the encoded surface glycoprotein represents an attractive target for cancer immunotherapies. Furthermore, the extracellular domain of HER-2/neu is released from the cell surface by proteolytic cleavage. In the present experiments, we investigated the potential biologic effects of soluble HER-2/neu with particular emphasis on its interaction with anti-HER-2/neu antibodies. A monoclonal antibody specific for the extracellular domain of HER-2/neu dose dependently inhibited the proliferation of highly HER-2/neu-expressing SK-BR-3 and BT-474 breast cancer cells but had no effect on the proliferation of weakly to moderately HER-2/neu-expressing MCF-7, HBL-100 and ZR-75-1 breast cells. Addition of SK-BR-3 or BT-474 cell supernatants with high concentrations of soluble HER-2/neu led to a neutralization of anti-HER-2/neu antibody-mediated inhibition of proliferation due to a binding of soluble HER-2/neu by the antibody, which could be demonstrated by immunoprecipitation. Furthermore, the ability of anti-HER-2/neu antibodies to mediate antibody-dependent cellular cytotoxicity (ADCC) by lymphokine-activated killer cells was assessed. Cytolysis of SK-BR-3 tumor cells was increased significantly in the presence of anti-HER-2/neu antibodies. Similar to the proliferation inhibition, ADCC was neutralized by addition of soluble HER-2/neu-containing supernatants. Our data suggest that tumors rich in HER-2/neu might thus escape certain steps of immunologic control by neutralizing biologic activities of anti HER-2/neu antibodies due to the presence of soluble HER-2/neu.

Abstract
The proliferation response of human peripheral blood mononuclear cells (PBMC) to concanavalin A (con A) was tested in a medium with or without addition of fetal calf serum (FCS) or a serum substitute. The time profile of the proliferative response of PBMC to con A was different in cells cultured in a medium supplemented with or without FCS. This different pattern occurred for the con A-induced DNA-synthesis as well as for the RNA- or protein-synthesis. The peak proliferation rate and the stimulation index of proliferation of human PBMC to con A was also higher when the cells were cultured in a medium with 10% FCS compared to cells cultured in a FCS-free medium. Substitution of the fetal calf serum by a serum substitute even induced a profound inhibition of the de novo synthesis of DNA in human PBMC. The results indicate that a lymphocyte proliferation response to con A can still be obtained in a culture medium where no FCS was added, although a weaker stimulation occurred in comparison to a culture medium with FCS. However, addition of a serum substitute caused a marked inhibition of the lymphocyte proliferation rate.
