Psychosocial factors and mental health in cancer patients: opportunities for health promotion

A first step in planning health promotion with respect to mental health is analysing the factors that influence mental health. Diagnosis of the relevant variables may contribute to the design of effective health promotion programmes. In this paper the relationship between psychosocial factors and mental health status of cancer patients is discussed. The study investigates the relation between psychosocial factors like social support, generalized self-efficacy, feelings of loneliness, social mobilization and mental health among cancer suruivors (n = 480). Results reveal that mental health in cancer survivors is slightly lower than in a reference group from the general population. Generalized self-efficacy and feelings of loneliness are the major psychosocial factors related to mental health in cancer survivors. The implications for the design of health promotion activities using self-efficacy theory are discussed.

Work functioning beyond return to work past cancer diagnosis

Psychological capital and work functioning of workers with recurrent or metastatic cancer beyond return to work

ObjectivesThe existing studies among workers with a past cancer diagnosis have rarely focused on workers confronted with cancer recurrence or metastases specifically, so knowledge is lacking. The aim of this study, therefore, was to investigate the work functioning (work ability, burnout complaints, and work engagement) of workers with recurrent or metastasized cancer. Furthermore, the association of psychological capital (hope, optimism, resilience, and self-efficacy) with work functioning was studied.MethodsData from a survey study among workers 2–10 years past cancer diagnosis were used (N = 750); 73% reported a diagnosis of breast cancer and 27% a diagnosis of cancer other than breast cancer. Analysis of variance was used to compare participants with and without cancer recurrence or metastases regarding work functioning (work ability, burnout complaints, and work engagement) and psychological capital (hope, optimism, resilience, and self-efficacy). Multivariate regression analyses were used to analyze the association of type of cancer and psychological capital with work functioning among workers with cancer recurrence or metastatic cancer (n = 54), controlling for age.ResultsWork ability is significantly lower among workers with cancer recurrence or metastases (controlling for age); however, burnout complaints and work engagement are at comparable levels. Among workers with cancer recurrence or metastases, a higher level of hope is positively associated with work ability and work engagement, and a higher level of hope or resilience is negatively associated with burnout complaints.Significance of resultsAmong workers with cancer recurrence or metastases, work ability needs attention. Furthermore, especially the element hope of psychological capital is important to focus on because of the association with more favorable work functioning in general. The clinical psycho-oncological practice may benefit from these insights in guiding this vulnerable group of workers who are living with active cancer and many uncertainties.

Accounting for Sexual Issues Related to Cancer

Cancer and its treatments cause significant changes in sexuality that affect the quality of life of both patients and their partners. As these issues are not always discussed with healthcare professionals, cancer patients turn to online health communities to find answers to questions or for emotional support pertaining to sexual issues. By using a discursive psychological perspective, we explore the social actions that participants in online health forums perform when discussing sexuality. Data were collected by entering search terms in the search bars of three online health forums. Our analysis of 213 threads, containing 1,275 posts, provides insight into how participants who present themselves as women with cancer account for their sexual issues and, in doing so, orient to two intertwined norms: Having untroubled sex is part of a couple’s relationship, and male partners are entitled to having untroubled sex. We discuss the potential harmful consequences of orienting to norms related to sexual behaviour. Yet, our findings can also help healthcare professionals in broaching the topic of sexuality in conversations with cancer patients. The insights of this study into what female patients themselves treat as relevant can assist health professionals in better aligning with patients’ interactional concerns.

Drug-induced caspase 8 upregulation sensitises cisplatin-resistant ovarian carcinoma cells to rhTRAIL-induced apoptosis

Background: Drug resistance is a major problem in ovarian cancer. Triggering apoptosis using death ligands such as tumour necrosis factor-related apoptosis inducing ligand (TRAIL) might overcome chemoresistance. Methods: We investigated whether acquired cisplatin resistance affects sensitivity to recombinant human (rh) TRAIL alone or in combination with cisplatin in an ovarian cancer cell line model consisting of A2780 and its cisplatin-resistant subline CP70. Results: Combining cisplatin and rhTRAIL strongly enhanced apoptosis in both cell lines. CP70 expressed less caspase 8 protein, whereas mRNA levels were similar compared with A2780. Pre-exposure of particularly CP70 to cisplatin resulted in strongly elevated caspase 8 protein and mRNA levels. Caspase 8 mRNA turnover and protein stability in the presence or absence of cisplatin did not differ between both cell lines. Cisplatin-induced caspase 8 protein levels were essential for the rhTRAIL-sensitising effect as demonstrated using caspase 8 small-interfering RNA (siRNA) and caspase-8 overexpressing constructs. Cellular FLICE-inhibitory protein (c-FLIP) and p53 siRNA experiments showed that neither an altered caspase 8/c-FLIP ratio nor a p53-dependent increase in DR5 membrane expression following cisplatin were involved in rhTRAIL sensitisation. Conclusion: Cisplatin enhances rhTRAIL-induced apoptosis in cisplatin-resistant ovarian cancer cells, and induction of caspase 8 protein expression is the key factor of rhTRAIL sensitisation. © 2011 Cancer Research UK All rights reserved.

Tailoring of exercise and dietary interventions to adverse effects and existing comorbidities in patients with ovarian cancer receiving chemotherapy

Purpose: This study aims to capture the complex clinical reasoning process during tailoring of exercise and dietary interventions to adverse effects and comorbidities of patients with ovarian cancer receiving chemotherapy. Methods: Clinical vignettes were presented to expert physical therapists (n = 4) and dietitians (n = 3). Using the think aloud method, these experts were asked to verbalize their clinical reasoning on how they would tailor the intervention to adverse effects of ovarian cancer and its treatment and comorbidities. Clinical reasoning steps were categorized in questions raised to obtain additional information; anticipated answers; and actions to be taken. Questions and actions were labeled according to the evidence-based practice model. Results: Questions to obtain additional information were frequently related to the patients’ capacities, safety or the etiology of health issues. Various hypothetical answers were proposed which led to different actions. Suggested actions by the experts included extensive monitoring of symptoms and parameters, specific adaptations to the exercise protocol and dietary-related patient education. Conclusions: Our study obtained insight into the complex process of clinical reasoning, in which a variety of patient-related variables are used to tailor interventions. This insight can be useful for description and fidelity assessment of interventions and training of healthcare professionals.
