Stress and posttraumatic growth among survivors of breast cancer: A test of curvilinear effects.

The purpose of the current study was to test the curvilinear associations between experiences of stress and posttraumatic growth among female breast cancer survivors. Participants (n = 193; 86% Caucasian; 80% diagnosed with Stage I or II cancer) completed self-report questionnaires assessing socio-demographic and medical information, perceived general stress, cancer-specific stress, and posttraumatic growth. Two hierarchical regression models tested the associations between general and cancer-specific stress and posttraumatic growth. After controlling for the effects of age, education, and time since diagnosis, there was a significant curvilinear effect of general stress on posttraumatic growth. Moderate levels of general stress were associated with the greatest posttraumatic growth. Cancer-specific stress was not associated with posttraumatic growth. These findings suggest that stress can be adaptive in the aftermath of cancer treatments and different manifestations of stress may require individualized intervention. Future research studies are needed to better understand and contextualize these findings among other cancer populations.

The sexual health of female rectal and anal cancer survivors: results of a pilot randomized psycho-educational intervention trial.

Sexual dysfunction is a frequently reported consequence of rectal/anal cancer treatment for female patients. The purpose of this study was to conduct a small randomized controlled trial to assess the efficacy of a telephone-based, four-session Cancer Survivorship Intervention-Sexual Health (CSI-SH). Participants (N = 70) were stratified by chemotherapy, stoma, and menopause statuses before randomization to CSI-SH or assessment only (AO). Participants were assessed at baseline, 4months (follow-up 1), and 8months (follow-up 2). The intervention had medium effect sizes from baseline to follow-up 1, which decreased by follow-up 2. Effect sizes were larger among the 41 sexually active women. Unadjusted means at the follow-ups were not significantly different between the treatment arms. Adjusting for baseline scores, demographics, and medical variables, the intervention arm had significantly better emotional functioning at follow-ups 1 and 2 and less cancer-specific stress at follow-up 1 compared to the AO arm. The data supported the hypothesized effects on improved sexual and psychological functioning and quality of life in CSI-SH female rectal/anal cancer survivors compared to the AO condition. This pilot study (N = 70) of CSI-SH supported the impact of this intervention on sexual and psychological functioning and quality of life on rectal and anal cancer survivors compared with an AO condition. However, intervention effects were stronger at follow-up 1 as compared to follow-up 2 and were stronger for sexually active women. Women may benefit from a brief, four-session, sexual health intervention after treatment from rectal and anal cancer.

Stress and self-efficacy predict psychological adjustment at diagnosis of prostate cancer.

Prostate cancer is the most frequently non-skin cancer diagnosed among men. Diagnosis, a significant burden, generates many challenges which impact on emotional adjustment and so warrants further investigation. Most studies to date however, have been carried out at or post treatment with an emphasis on functional quality of life outcomes. Men recently diagnosed with localised prostate cancer (N = 89) attending a Rapid Access Prostate Clinic to discuss treatment options completed self report questionnaires on stress, self-efficacy, and mood. Information on age and disease status was gathered from hospital records. Self-efficacy and stress together explained more than half of the variance on anxiety and depression. Self-efficacy explained variance on all 6 emotional domains of the POMS (ranging from 5–25%) with high scores linked to good emotional adjustment. Perceived global and cancer specific stress also explained variance on the 6 emotional domains of the POMS (8–31%) with high stress linked to poor mood. These findings extend understanding of the role of efficacy beliefs and stress appraisal in predicting emotional adjustment in men at diagnosis and identify those at risk for poor adaptation at this time. Such identification may lead to more effective patient management.

Cancer-Specific Stress and Mood Disturbance: Implications for Symptom Perception, Quality of Life, and Immune Response in Women Shortly after Diagnosis of Breast Cancer

Purpose. To determine the levels of cancer-specific stress and mood disturbance in women shortly after diagnosis of breast cancer and to assess their associations with symptom perception, quality of life, and immune response. Design. Descriptive and correlational. Sample and Setting. One hundred women with newly diagnosed breast cancer were recruited from interdisciplinary breast clinics. Methods. Baseline data were collected using standardized questionnaires and established bioassay prior to the initiation of cancer adjuvant therapy. Blood samples were collected about the same time of day. Results. High cancer-specific stress was significantly correlated with high mood disturbance, which, in turn, was correlated with high symptom perception, poor quality of life, and an immune profile indicating high neutrophils and low lymphocytes. Conclusions. High cancer-specific stress and related mood disturbance show extensive negative relationships with multiple behavioral, clinical, and biological factors. Implications for Nursing. Routine screening for cancer-related stress and mood disturbance should be incorporated into nursing practice for all patients diagnosed with cancer. Given broad negative associations with other biobehavioral factors, early identification of patients at risk and provision and evaluation of stress and mood management programs may have a beneficial effect on subsequent health outcomes over time.

Cognitive‐behavioural stress management enhances adjustment in women with breast cancer

This randomized controlled trial examines whether a briefer cognitive-behavioural (CBT) stress management intervention than the norm can reduce stress and distress and enhance benefit finding in women with breast cancer. It further aims to identify characteristics of those women most likely to benefit from the intervention. A randomized controlled trial was conducted to assess the efficacy of a psychological intervention. Women (N = 355) who had undergone surgery for breast cancer 4 months earlier, the majority of whom were currently undergoing adjuvant therapy, completed questionnaires assessing global and cancer-specific stress, depression, anxiety, optimism and benefit finding. They were randomly assigned to a 5-week group cognitive-behavioural stress management (CBSM) programme plus standard care or standard care only. Reassessment occurred post-intervention and 12 months later. Analyses of variance revealed that patients who received the intervention showed significant lowering of global stress and anxiety and increased benefit finding compared to controls. These differences, however, were not maintained at 12 months. Effects of the intervention were moderated by stress such that women with high global stress at baseline showed greater reduction in both stress and anxiety. A CBSM intervention, which was briefer than the norm (5 weeks vs. 9-20 weeks), had beneficial effects on adjustment for women with breast cancer and was particularly effective for those with increased global stress. Screening on this basis may facilitate optimal and cost-effective psychological treatment.

Global stress predicts both positive and negative emotional adjustment at diagnosis and post‐surgery in women with breast cancer

Individual differences in stress appraisal, coping, optimism and social support have contributed to variability in adjustment to breast cancer, but less is known about their relative influence particularly at diagnosis. The purpose of this study was to compare the predictive role of these variables on both positive and negative adjustment in a sample of recently diagnosed women. Data was collected from 241 women at diagnosis and post-surgery (4 months later). They completed questionnaires which assessed global and cancer-specific stress, general and cancer-specific coping, emotional adjustment (depression, anxiety, positive and negative affect) at Times 1 and 2 and benefit finding at Time 2. Hierarchical regression analyses (all p < 0.01) taking account of age and cancer related variables (disease stage and type of surgery) showed that stress appraisal was the strongest and most consistent predictor of adjustment. The coping strategies, while significant, were less powerful predictors of emotional adjustment, but they explained more variance than stress on benefit finding. Stress and coping outweighed the impact of social support and optimism. Global appraisal of stress was the most powerful predictor in the model, and findings suggest that it contributes to patients' affective status, indicating that women should be screened as part of the diagnostic process to identify those at risk for poor adaptation to the illness.

Impact of breast cancer recurrence and cancer-specific stress on spouse health and immune function

Spouses of cancer patients are at-risk for poor psychological and physical health as they cope with the complex nature of the disease and fears of losing their partner. Moreover, spouses often serve as patients' primary informal caregivers, a group that evidences poor outcomes across a variety of domains. The present study examines the relative contributions of cancer recurrence - a cancer-specific stressful event - and the subjective experience of cancer-specific stress (IES) in a sample of male spouses of breast cancer survivors. We hypothesized that stress would contribute to poorer physical health and compromised immune function. Spouses (recurrence; n=16) of patients who were coping with their first recurrence were matched to spouses of patients with no evidence of disease (disease-free; n=16). Self-reported physical health (physical symptoms and fatigue) and immune function [T-cell blastogenic response to the mitogens Concanavalin A (ConA) and phytohemagglutanin (PHA) and T3 monoclonal antibody (T3 Mab)] were included as outcomes. Results indicated that patient recurrence status was not a significant unique predictor of physical health or immune function; rather, among all spouses, cancer-specific stress symptoms were associated with increased physical symptoms and altered T-cell blastogenesis. These data suggest that the health implications of caregiving for spouses of cancer survivors is more strongly linked to their subjective experience of cancer as stressful, rather than simply the patients' disease status.

Sexual Morbidity Associated With Poorer Psychological Adjustment Among Gynecological Cancer Survivors

Sexual morbidity is a distressing and undertreated problem in gynecological cancer survivorship known to occur early and persist well beyond the period of physical recovery. Although often studied as a separate domain, sexuality represents an integral component of psychological adjustment and quality of life (QoL) that is adversely affected by cancer treatments. The present study tests the association between sexual morbidity, and adverse psychological adjustment and QoL outcomes. A cross-sectional design was used. The participants were gynecological (cervical, endometrial, ovarian, and vulvar) cancer survivors who were partnered (N = 186), whose cancer was diagnosed 2 to 10 years previously, and who were at least 6 months post any cancer therapy. Most had been found to have early-stage disease (70%) and were treated with hysterectomy (77%), chemotherapy (43%), and/or radiotherapy (23%). Sexual morbidity was operationalized as a multidimensional construct including sexual behavior, sexual functioning, and subjective sexual satisfaction, assessed by patient self-report. Outcomes included self-reported depressive symptoms, traumatic stress symptoms, cancer-specific stress, stress about body changes, and QoL. Nurse-rated of performance status and disruptive signs/symptoms of treatment toxicity, as well as relevant sociodemographic and disease variables were collected as potential controls. Hierarchical multiple regression analyses tested sexual morbidity as a predictor of poor outcomes. All statistical models were significant, accounting for 12% to 53% of the variance in psychological adjustment/QoL. Sexual morbidity covaried with worsened depressive symptoms, body change stress, and psychological QoL beyond the negative contributions of (older) age, (poorer) performance status, and (greater) fatigue. Notably, disease and treatment variables were not statistically significant correlates of psychological adjustment or QoL. These findings suggest that prevention or treatment of sexual morbidity might foster improved psychological adjustment/QoL. Given the high rates of sexual morbidity in this population and the connection between sexuality and broader psychological adjustment/QoL, there is a clear need for better integration of sexuality rehabilitation into routine clinical care.

Sexual well-being among partnered women with breast cancer recurrence.

A woman's risk for sexual disruption after breast cancer recurrence has received little clinical or research attention. Breast cancer patients recently diagnosed with recurrence (n = 60) were initially assessed at baseline and completed follow-ups at 4, 8, and 12 months. They were compared by age, stage, and duration and frequency of follow-up with matched patients who remained disease free (n = 120). Using linear mixed modeling, the groups were compared in their trajectories of change on measures of sexuality, relationship satisfaction, cancer-specific stress, and physical functioning. Recurrence subgroups, those with locoregional versus distant disease and those younger versus older than 52 years, were also compared. At baseline, the recurrence group had significantly lower intercourse frequency and physical functioning compared with the disease-free group and these differences were maintained. There were no significant differences in the frequencies of kissing or sexual and relationship satisfactions. For the recurrence group patients, the heightened stress of the diagnostic/early recurrence treatment period declined to the lower disease-free levels by 12 months. This effect was largely due to improvement of the patients with distant disease. Finally, sexual changes were most notable for younger patients. To our knowledge, this is the first longitudinal, controlled study of sexuality-sexuality in the context of other quality of life domains-for women coping with recurrence. Despite disruption, patients maintained their sexual lives. Younger and distant recurrence patients, however, may have greatest risk of sexual disruption. The factors contributing to sexual disruption remain unknown, and studies investigating strategies to help patients maintain this aspect of quality of life are needed.

Psychological responses to cancer recurrence

There is a dearth of knowledge regarding the psychological responses to a diagnosis of cancer recurrence. An ongoing randomized clinical trial provided the context for prospective study. Women with Stage II/III breast carcinoma (N = 227) were initially assessed after their diagnosis/surgery and before adjuvant therapy and then reassessed every 6 months. Eight years into the trial, 30 patients had recurred (R) and were assessed shortly after receiving their second diagnosis. Their data were compared with a sample of trial patients who had no evidence of disease (disease free [DF]; n = 90). The groups were matched on study arm, disease stage, estrogen receptor status, menopausal status, and time since initial diagnosis. As hypothesized, patients' cancer-specific stress at recurrence in the R group was higher (P < 0.05) than stress levels for the DF group at the equivalent point in time. Importantly, the R group reported stress for their recurrent diagnosis equivalent to that reported for their initial diagnosis. Identical results were found for measures of health status and symptomatology. In contrast, analyses for emotional distress and social functioning showed no pattern of disruption for the R group at cancer recurrence and levels equivalent to that of the DF group. To the authors' knowledge, this was the first controlled, prospective psychological analysis of patients' responses to cancer recurrence. The findings were consistent with a learning theory conceptualization of the cancer stressor. Patients' stress was "compartmentalized" and did not, at least in the early weeks, result in diffuse emotional distress and quality of life disruption, underscoring the resilience of patients when confronted with cancer recurrence.

Quality of life of breast cancer survivors after a recurrence: a follow-up study.

Previous studies on breast cancer recurrence provide a mixed picture of the quality of life of women following a recurrence. To clarify the picture, the present study addresses some previous methodological concerns by offering a multidimensional assessment with follow-up, a matched comparison group of disease-free survivors, and a closer look at the nature of recurrence (local versus metastatic). Fifty-Four of 817 women who participated in an earlier study experienced a recurrence at follow-up, and are compared to a matched sample of 54 women who remained disease-free. Analyses indicate that women who had a recurrence report significantly poorer functioning on various health-related quality of life (HRQOL) domains compared to women who remained disease-free. However, the differences appear to be largely due to the poorer HRQOL of women with metastatic disease. Although women who had a recurrence report good mood, low stress, and good quality of interpersonal relationships, they report significantly higher cancer-specific stress compared to disease-free women at follow-up. Women who had a recurrence also report experiencing both more meaning and vulnerability as a result of breast cancer than disease-free women, but report similar levels of spirituality and benefit-finding at follow-up as disease-free women. These results suggest that although women report relatively good psychosocial adjustment following a recurrence, cancer-specific domains of quality of life are most likely to be negatively affected. These results may be useful in identifying individuals with breast cancer recurrences who are most in need of psychosocial services.

Psychological problems of cancer patients: a cancer distress screening with a cancer-specific questionnaire.

The purpose of this study was to assess the psychological distress of cancer patients in a disease-specific manner as well as the demographic and medical variables that have an impact on the distress. Psychological distress was assessed with the Questionnaire on Stress in Cancer Patients revised version, which has been developed and psychometrically evaluated in Germany. It consists of items about 23 cancer-specific stress situations, which have to be answered in terms of relevance and amount of distress. A heterogeneous sample of 1721 cancer in- and outpatients was assessed. For the total group, the most important distress is the fear of disease progression. We consider between 23.4% (ca. of the upper gastrointestinal tract) and 40.9% (breast cancer patients) as highly distressed. The most distressed diagnostic subgroups are patients with soft tissue tumours and breast cancer patients. There are no global (general) stress factors, as the relevant demographic and medical ‘risk factors’ varied between the diagnostic subgroups. Cancer-specific distress questionnaires give a more precise insight into patients' experience than general or psychiatric questionnaires. They are not only used in large screening studies but also in routine medicine, particularly when the objective is to identify patients to whom psycho-oncological support is to be given.

Patient and Partner Quality of Life and Psychosocial Adjustment Following Radical Prostatectomy

We prospectively examined differences in quality of life and psychosocial adjustment in 80 prostate cancer patients and their partners (n = 65) beginning before radical prostatectomy and proceeding across the first year postsurgery. Both members of the couple experienced significant changes associated with the patient's cancer, however their experiences differed in some regards. Patients experienced reprieve from emotional distress and negative affect immediately following surgery despite worsened physical functioning. Partner quality of life and psychosocial adjustment scores were generally more constant from presurgery to postsurgery, with improvements noted 1 year later. For both patients and partners, cancer-specific stress symptoms declined progressively over the year. We also obtained partial support for the effectiveness of a single-session communication intervention on patient social/family wellbeing and partner general stress. Findings have implications for patient and partner adjustment following radical prostatectomy, and attest to the importance of incorporating partner evaluations into psychosocial oncology research.

Risk perception, screening practice and interest in genetic testing among unaffected men in families with hereditary prostate cancer

Approximately 5–10% of prostate cancer cases are caused by dominantly inherited susceptibility to the disease. Although advances have been made in research concerning the genetic mechanisms of hereditary prostate cancer, little is known about the psychological consequences for men at high risk of developing the disease. The aims of the present study were to examine risk perception, interest in genetic investigations, cancer-specific worry, and screening practice among unaffected men, aged 40–72 years old, with a pedigree consistent with hereditary prostate cancer and an estimated lifetime risk of prostate cancer of 35–45%. A questionnaire was sent by mail to 120 subjects, of whom 110 responded. Most of the men (n=90, 82%) worried about having an inherited susceptibility to prostate cancer, and 34 (31%) claimed that worry about prostate cancer affected their daily life (3 (3%) fairly much, 31 (28%) slightly). As many as 40% of the study subjects perceived their lifetime risk of prostate cancer as 67% or more. Perceived high risk was associated with symptoms of depression and with cancer worry affecting daily living. Two-thirds of the men aged 50 years old or more were regularly screened for prostate cancer. Subjects with high levels of cancer-specific stress, as measured by the avoidance subscale of the Impact of Event Scale, were less likely to opt for screening. Almost all of the men (94%) were interested in presymptomatic genetic testing (84 (76%) “definitely yes” and 20 (18%) “probably yes”). We conclude that hereditary susceptibility to prostate cancer has significant psychological consequences although it rarely causes psychiatric morbidity. The present study underlines the importance of giving thorough, repeated information to men at high risk of prostate cancer.
