Physical symptoms, distress, and breast cancer risk perceptions in women with benign breast problems.

Physical symptoms, general and breast cancer-specific distress, and perceived breast cancer risk were assessed in 66 women with benign breast problems (BBP) and 66 age-matched healthy comparison (HC) women. BBP women reported significantly greater worry about breast cancer than HC women. Breast symptom incidence and breast cancer risk perceptions were found to mediate group differences in breast cancer worry. Hierarchical regression analyses indicated that perceptions of control over a potential breast cancer prognosis moderate the impact of breast symptoms on reports of breast cancer worry. Implications for risk counseling with BBP women are discussed. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Posttraumatic growth following breast cancer: A controlled comparison study.

Cancer may be viewed as a psychosocial transition with the potential for positive and negative outcomes. This cross-sectional study (a) compared breast cancer (BC) survivors' (n?=?70) self-reports of depression, well-being, and posttraumatic growth with those of age- and education-matched healthy comparison women (n?=?70) and (b) identified correlates of posttraumatic growth among BC survivors. Groups did not differ in depression or well-being, but the BC group showed a pattern of greater posttraumatic growth, particularly in relating to others, appreciation of life, and spiritual change. BC participants' posttraumatic growth was unrelated to distress or well-being but was positively associated with perceived life-threat, prior talking about breast cancer, income, and time since diagnosis. Research that has focused solely on detection of distress and its correlates may paint an incomplete and potentially misleading picture of adjustment to cancer.

A randomized trial of breast cancer risk counseling: Interacting effects of counseling, educational level, and coping style.

The authors evaluated the impact of individualized breast cancer risk counseling (BCRC) on breast-cancer-specific distress and general distress in 239 women with a family history of breast cancer. Following a baseline assessment of demographics, risk factors, coping styles, and distress, participants were assigned randomly to receive either BCRC or general health education (GHE; i.e., control group). After controlling for education level, women who received BCRC had significantly less breast-cancer-specific distress at 3-month follow-up compared with women who received GHE. A significant Education Level?*?Treatment Group interaction indicated that the psychological benefits of BCRC were greater for women with less formal education. In both the BCRC and GHE groups, participants who had monitoring coping styles exhibited increases in general distress from baseline to follow-up.

Psychological adjustment among African American breast cancer patients: One-year follow-up results of a randomized psychoeducational group intervention.

The effectiveness of support group interventions for cancer patients has been established among White patients but has been virtually unstudied among minority patients. The current study represents the 1st randomized support group intervention targeted to African American women with breast cancer. Participants (N = 73) with nonmetastatic breast cancer were randomly assigned to an 8-week group intervention or an assessment-only control condition At 12 months, the intervention resulted in improved mood as well as improved general and cancer-specific psychological functioning among women with greater baseline distress or lower income. Subsequent research is needed to address effective methods of enrolling and following women with fewer psychosocial and financial resources, as they were the most likely to benefit from this particular intervention.

Effects of coping style and BRCA1 and BRCA2 test results on anxiety among women participating in genetic counseling and testing for breast and ovarian cancer risk.

Using the monitoring process model (MPM), the authors examined the immediate effects of coping style and test results on the psychological distress of women at increased risk for breast and/or ovarian cancers. Cases selected for analysis were 107 probands and relatives of positive probands participating in genetic counseling and testing for heritable cancer risk. Specifically, the authors explored the relationships among coping style (high and low monitoring), test results (BRCA1 and BRCA2 mutation carrier and noncarrier status), and psychological distress (state anxiety). Consistent with the MPM, higher monitoring was associated with greater psychological distress while anticipating genetic test results. After test results were disclosed, greater distress was associated with testing positive for a mutation. The implications of the findings for breast and ovarian cancer patients are discussed.

Coping with a breast cancer diagnosis: A prospective study.

Employing the stress and coping theory of R. S. Lazarus and S. Folkman (1984), this study followed 117 women age 40+ regarding personality, cognitive appraisal, coping, and mood variables before breast biopsy, after diagnosis, and, for those who had cancer, after surgery. Upon biopsy, 36 received a cancer diagnosis, and 81 received a benign diagnosis. The 2 groups did not differ on appraisals, coping, or affect before diagnosis. With prebiopsy affect controlled, cancer patients reported more negative affect postbiopsy than did benign patients. Postsurgery, cancer patients expressed less vigor and more fatigue than benign patients, but the groups did not differ on other negative emotions. Prebiopsy, psychosocial predictors accounted for 54% and 29% of the variance in negative and positive emotion, respectively. Prebiopsy variables also predicted postbiopsy and postsurgery mood; cognitive coping was a particularly important predictor of high distress and low vigor.

Optimism, Perceived Risk of Breast Cancer, and Cancer Worry Among a Community-Based Sample of Women.

Optimism is frequently inversely associated with distress; however, less is known about the mechanisms underlying this relationship. Optimism can be defined as having a generalized positive expectancy about the future. The authors hypothesized that a specific expectancy might mediate the relationship between optimism and distress. That model was tested using perceived risk of breast cancer as a specific measure of expectancy and cancer worry as a measure of distress in a community-based sample of 1,366 women. It was hypothesized that optimism would be inversely associated with cancer worry and that perceived risk of breast cancer would mediate the relationship between optimism and cancer worry. Multiple regression analyses revealed that perceived risk partially mediated the relationship between optimism and cancer worry. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Specific worry about breast cancer predicts mammography use in women at risk for breast and ovarian cancer.

This longitudinal study examined predictors of mammography use among women with a family history of breast cancer participating in a risk assessment and surveillance program (N?=?213). Assessed were background variables (age, prior mammography utilization), cognitive variables (perceived vulnerability), and affective variables (cancer worry and general distress). Results of logistic regression analyses predicting adherence 1 year after baseline contact, in which variables of prior utilization, feelings of vulnerability, and general distress were controlled for, indicated that and age were significant predictors of mammography adherence. Results suggest that moderate levels of cancer worry facilitate, rather than undermine, adherence. The results have implications for the construction of educational messages that should be designed to acknowledge feelings of cancer-specific worry and to provide guidance in health protective behaviors.

Effects of various phosphodiesterase-inhibitors, forskolin, and sodium nitroprusside on porcine detrusor smooth muscle tonic responses to muscarinergic stimulation and cyclic nucleotide levels in vitro

The Gail model is being used increasingly to determine individual breast cancer risk and to tailor preventive health recommendations accordingly. Although widely known to the medical and biostatistical communities, the risk factors included in the model may not be salient to the women to whom the model is being applied. This study explored the relationship of the individual Gail model risk factors to perceived risk of breast cancer and prior breast cancer screening among women with a family history of breast cancer. Data from baseline interviews with 969 women found a striking disparity between the objective risk factors included in the model and the accuracy of perceived risk and screening behaviors of this population, particularly among women over the age of 50 years. Risk perception accuracy was unrelated to all of the Gail model risk factors for all age groups. Reported mammography adherence was only associated with having had a breast biopsy in both age groups. Breast self examination (BSE) practice was independent of all measured factors for both age groups. These findings support the need for further research to identify additional determinants of risk perception and motivators of screening behavior.     

Identification and prediction of distress trajectories in the first year after a breast cancer diagnosis.

Objective: In this article, we aim to (a) identify distinct trajectories of psychological distress in the first year after a breast cancer diagnosis in women treated with adjuvant therapy and (b) explore possible predictors of these trajectories, that is, demographic, medical, and personal characteristics. Method: The 171 patients were assessed after diagnosis, after surgery, after adjuvant treatment, in the reentry phase, and in the (short-term) survivorship phase (2 and 6 months after the end of treatment, respectively). Main Outcome Measure: Psychological distress was assessed with the 12-item General Health Questionnaire. Results: There were four trajectories of distress: a group that experienced no distress (36.3%), a group that experienced distress only in the active treatment phase (33.3%), a group that experienced distress in the reentry and survivorship phase (15.2%), and a group that experienced chronic distress (15.2%). Personality and physical complaints resulting from adjuvant treatment could distinguish the distress trajectories. Mastery was the only unique predictor. Conclusion: Most patients were not distressed in response to breast cancer or only temporarily so. Yet, a minority of patients became or remained distressed after the end of treatment.

Social support as a mediator of optimism and distress in breast cancer survivors.

Breast cancer patients can experience emotional distress as a result of diagnosis and treatment. Higher levels of optimism and social support are associated with less emotional distress in cancer patients. This 12-month prospective study followed 69 women who had completed treatment for Stages 0-11 breast cancer. At 3-month intervals, participants completed measures of mood disturbance, optimism, and social support. As hypothesized, affective social support mediated the relationship between optimism and distress in early-stage breast cancer survivors at baseline and 6 months but not at 1 year. In contrast, confidant social support did not mediate the optimism-distress relationship at any time point. Clinical and research implications of these findings are discussed.

Partner unsupportive responses, avoidant coping, and distress among women with early stage breast cancer: Patient and partner perspectives.

This 18-month longitudinal study examined the associations among partner unsupportive behavior, avoidant coping, and distress experienced by 219 women with early stage breast cancer. The role of patient and partner ratings of unsupportive behavior were evaluated. Results indicated that patient and partner ratings of unsupportive behavior were highly correlated. Growth curve modeling suggested that unsupportive behavior, from both patient and partner perspectives, predicted more avoidant coping and distress. When partner and patient perceptions were placed in the same model, patient perceptions mediated the association between partners' ratings of their unsupportive behavior and patient distress. Avoidance also mediated the association between unsupportive behavior and distress, extending prior cross-sectional findings. Results highlight the long-term detrimental effects of partners' unsupportive behavior on the quality of life of women with early stage breast cancer.

Long-term effects of educational and peer discussion group interventions on adjustment to breast cancer.

The authors report a 3-year follow-up of the effects of 8-week support group interventions on the quality of life of women with early stage breast cancer. Shortly after diagnosis, women were randomly assigned to 1 of 4 conditions: control, education, peer discussion, and education plus peer discussion. The education group intervention focused on providing information to enhance control over the illness experience, whereas the peer discussion group intervention focused on providing emotional support through the expression of feelings. Consistent with the results that emerged 6 months after the interventions (V. S. Helgeson, S. Cohen, R. Schulz & J. Yasko, 1999), the authors found that the benefits of the education intervention were maintained over a 3-year period N?=?252) although effects dissipated with time. The authors continued to find no benefits of the peer discussion intervention, either alone or in combination with education. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Effects of fetal calf serum and disruption of cadherin function on the formation of bile canaliculi between hepatocytes

The polarization of hepatocytes to form a connected network of bile canaliculi (BC) is necessary for the function of the liver. Hepatocyte polarization may be controlled by soluble factors and/or physical interactions between cells. Monolayer cultures of embryonic chicken hepatocytes in DMEM supplemented with ornithine, dexamethasone, and insulin express BC-specific antigens for at least 7 days. However, BC-specific antigen expression is lost within 3 days of culture initiation in DMEM containing 10% fetal calf serum. The dedifferentiating effects of fetal calf serum (FCS) can be reversed. Furthermore, cultures in medium containing ornithine, dexamethasone, insulin, and 10% FCS appear identical to cultures grown in 10% FCS alone. Thus FCS contains a soluble inhibitor of hepatocyte polarization. Aggregate cultures grown in suspension maintain hepatocyte polarization for 10-12 days. This may be due to the increased cell-cell contact between hepatocytes in aggregate culture or to more normal contact with the extracellular matrix. We have evaluated the role of cadherin-mediated interactions on hepatocyte polarization. Anti-E-cadherin Fab' fragments disrupted the formation of long networks of BC in monolayer cultures but did not stop polarized expression of BC-specific antigens. The BC antigens in anti-E-cadherin-treated cells were concentrated in small areas between cells and were present at lower levels uniformly on the cell surface. These results indicate that E-cadherin is required for the formation of extended BC networks, but that other factors are responsible for maintaining the synthesis and localization of BC-specific antigens.     

Emotional distress following genetic testing for hereditary breast and ovarian cancer: A meta-analytic review.

Objective: Meta-analysis was used to synthesize results of studies on emotional consequences of predictive genetic testing for BRCA1/2 mutations conferring increased risk of breast and ovarian cancer. Design: Studies assessing anxiety or cancer-specific distress before and after provision of test results (k = 20) were analyzed using a random-effects model. Moderator variables included country of data collection and personal cancer history of study participants. Main Outcome Measures: Standardized mean gain effect sizes were calculated for mutation carriers, noncarriers, and those with inconclusive results over short (0–4 weeks), moderate (5–24 weeks), or long (25–52 weeks) periods of time after testing. Results: Distress among carriers increased shortly after receiving results and returned to pretesting levels over time. Distress among noncarriers and those with inconclusive results decreased over time. Some distress patterns differed in studies conducted outside the United States and for individuals with varying cancer histories. Conclusion: Results underscore the importance of time; changes in distress observed shortly after test-result disclosure frequently differed from the pattern of distress seen subsequently. Although emotional consequences of this testing appear minimal, it remains possible that testing may affect cognitive and behavioral outcomes, which have rarely been examined through meta-analysis. Testing may also affect understudied subgroups differently. (PsycINFO Database Record (c) 2010 APA, all rights reserved)     

Radial scars in benign breast-biopsy specimens and the risk of breast cancer

BACKGROUND: Radial scars are benign breast lesions of uncertain clinical significance. In particular, it is not known whether these lesions alter the risk of breast cancer in women with benign breast disease. We conducted a case-control study of women who had benign breast lesions with or without radial scars. METHODS: We reviewed benign breast-biopsy specimens from 1396 women enrolled in the Nurses' Health Study, including 255 women in whom breast cancer subsequently developed and 1141 women without subsequent breast cancer (controls). The controls were matched to the women with subsequent breast cancer according to age and the year when the benign lesion was identified. The median follow-up after biopsy of the benign lesions was 12 years. RESULTS: Radial scars were identified in biopsy specimens from 99 women (7.1 percent). Most biopsy specimens with radial scars had only one radial scar (60.6 percent), and they tended to be incidental microscopical findings (median size, 4.0 mm). The women with radial scars had a risk of breast cancer that was almost twice the risk of the women without scars, regardless of the histologic type of benign breast disease (relative risk, 1.8; 95 percent confidence interval, 1.1 to 2.9). Among women who had proliferative disease without atypia as compared with women who had nonproliferative disease, the relative risk of breast cancer was 3.0 (95 percent confidence interval, 1.7 to 5.5) for those with radial scars and 1.5 (95 percent confidence interval, 1.1 to 2.1) for those without radial scars. Among women with atypical hyperplasia as compared with women with nonproliferative disease, the relative risk of breast cancer was 5.8 (95 percent confidence interval, 2.7 to 12.7) for those with radial scars and 3.8 (95 percent confidence interval, 2.4 to 5.9) for those without radial scars. CONCLUSIONS: Radial scars are an independent histologic risk factor for breast cancer.     

Interdependence in women with breast cancer and their partners: An interindividual model of distress.

Objective: The aim of this investigation was to test whether interdependence in dyads living with breast cancer could account for person–partner crossover effects in distress outcomes. Method: The sample consisted of 95 dyads with early-stage breast cancer. By using reciprocal dyadic data from women with breast cancer and their partners, we fit a structural equation model of the actor–partner interdependence model to examine the interaction of participants’ depression and stress in predicting their partner’s health outcomes. Results: Results revealed a pattern of influence whereby the interaction of high levels of depression coupled with high levels of stress in women with breast cancer was associated with lowered physical health and well-being in their partners. Although depression seemed to be the key mechanism in predicting distressing outcomes, when depression was combined with any additional stress, the level of physical distress was significantly greater. Results provided preliminary empirical support for crossover effects in the physical well-being of close relational partners in a cancer-related context. Further, results showed that distressing outcomes need not be limited to emotional distress but can also include physical distress. Conclusions: The findings from this study illustrate why it is not sufficient to concentrate care solely on the patient with cancer. Monitoring the social well-being of patients as they go through the cancer process could be as important as assessing their psychological state or other peripheral biomarkers. This line of inquiry would be advanced by including methods other than self-report in assessments of psychological and physical health.

Psychosocial predictors of changing sleep patterns in aging women: A multiple pathway approach.

The authors of this investigation sought to examine changes in the sleep quality of older women over time and to determine whether dimensions of psychological well-being, health (subjective health and number of illnesses), and psychological distress (depression and anxiety) predict these changes. A secondary analysis was conducted with a longitudinal sample of aging women (Kwan, Love, Ryff, & Essex, 2003). Of 518 community-dwelling older women in the parent study, 115 women (baseline M age = 67 years, SD = 7.18) with data at baseline, 8 years, and 10 years were used for this investigation. Participants completed self-administered questionnaires and participated in in-home interviews and observations. Growth curve modeling was used to examine the overall linear trajectories of sleep quality. Growth mixture modeling was used to examine whether there were different patterns of change in sleep quality over time and to examine baseline predictors of each pattern. Sleep quality declined over time but not for all women. Two distinctly different sleep patterns emerged: good but declining sleep quality and disrupted sleep quality. Higher psychological well-being (positive relations with others, environmental mastery, personal growth, purpose in life, and self-acceptance), fewer illnesses, and lower depression scores at baseline predicted reduced odds for membership in the disrupted sleep group. Future research is needed to examine whether interventions focused on maintaining or enhancing psychological well-being could minimize later life declines in sleep quality.

Altering the course of marriage: The effect of PREP communication skills acquisition on couples' risk of becoming maritally distressed.

This longitudinal study predicted marital outcome from communication skills gained from participation in the Prevention and Relationship Enhancement Program (PREP; H. J. Markman, S. L. Blumberg & S. M. Stanley, 1989; Stanley et al., 2001) by 39 women and 38 men. Results were in the expected direction for men but not for women. Men's pre- to posttest decrease in negative communication and increase in positive communication predicted decreased risk of marital distress onset in men. Women's pre- to posttest increase in positive communication, which was related to self-reported avoidance of problem solving, predicted an increased risk of male and female distress onset. Couples with men relatively high on premarital risk factors demonstrated a greater benefit from men's positive communication skills acquisition.

Distress, personality, and mammography utilization among women with a family history of breast cancer.

The authors examined the impact of psychological distress and the personality construct of conscientiousness (as measured by the Neuroticism, Extraversion, and Openness—Five Factor Inventory) on mammography utilization among women who were at increased risk for breast cancer. Participants were 200 women who had at least 1 first degree relative with breast cancer. Overall, 80% of the participants had obtained a mammogram in the previous year. Analyses controlling for potential confounders (perceived risk, decisional balance, and physician recommendation for mammography), revealed that distress was negatively associated with mammography utilization among participants who were low in conscientiousness. Distress was not significantly related to mammography utilization among highly conscientious women. The results are discussed in terms of their implications regarding interventions designed to increase mammography utilization in this population.
