Women's decision making about risk-reducing strategies in the context of hereditary breast and ovarian cancer: a systematic review.

Women who have a mutation in the BRCA1 or BRCA2 genes have up to an 87% lifetime risk of breast cancer and up to a 40% lifetime risk of ovarian cancer. Cancer prevention and early detection strategies are often considered by these women to address this heightened risk. Risk-reducing strategies include risk-reducing mastectomy and oophorectomy, breast and ovarian cancer screening, and chemoprevention. This systematic literature review summarizes the factors and contexts that influence decision making related to cancer risk-reducing strategies among women at high-risk for hereditary breast and ovarian cancer. In the 43 published research articles reviewed, three main types of factors are identified that influence high-risk women’s decisions about risk-reducing strategies: a) medical and physical factors, b) psychological factors and c) social context factors. How these factors operate in women’s lives over time remains unknown, and would best be elucidated through prospective, longitudinal research, as well as qualitative research.

Preserving the Self: The Process of Decision Making About Hereditary Breast Cancer and Ovarian Cancer Risk Reduction:

Women who carry BRCA1 or BRCA2 (BRCA1/2) gene mutations have up to an 88% lifetime risk of breast cancer and up to a 65% lifetime risk of ovarian cancer. Strategies to address these risks include cancer screening and risk-reducing surgery (i.e., mastectomy and salpingo-oophorectomy). We conducted a grounded theory study with 22 BRCA1/2 mutation-carrier women to understand how women make decisions about these risk-reducing strategies. Preserving the self was the overarching decision-making process evident in the participants’ descriptions. This process was shaped by contextual conditions including the characteristics of health services, the nature of hereditary breast and ovarian cancer risk-reduction decisions, gendered roles, and the women’s perceived proximity to cancer. The women engaged in five decision-making styles, and these were characterized by the use of specific decision-making approaches. These findings provide theoretical insights that could inform the provision of decisional support to BRCA1/2 carriers.

Long-Term Outcomes and Complications in Patients With Craniopharyngioma: The British Columbia Cancer Agency Experience

PURPOSE We report long-term outcomes and complications of craniopharyngioma patients referred to our institution. METHODS AND MATERIALS Between 1971 and 2010, 123 consecutive patients received primary treatment for craniopharyngioma in British Columbia and were referred to our institution. The median age was 30 years (range, 2-80 years). Thirty-nine percent of patients were treated primarily with subtotal resection (STR) and radiation therapy (RT), 28% with STR alone, 15% with gross total resection, 11% with cyst drainage (CD) alone, 5% with CD+RT, and 2% with RT alone. Eight percent of patients received intracystic bleomycin (ICB) therapy. RESULTS Median follow-up was 8.9 years, and study endpoints were reported at 10 years. Ten-year Kaplan-Meier progression-free survival (PFS) was 46%. Patients treated with STR+RT or CD+RT had the highest PFS (82% and 83%, respectively). There were no significant differences between PFS after adjuvant versus salvage RT (84% vs 74%, respectively; P=.6). Disease-specific survival (DSS) was 88%, and overall survival (OS) was 80%. Primary treatment modality did not affect DSS or OS, while older age was a negative prognostic factor for OS but not DSS. Kaplan-Meier rates for visual deterioration, anterior pituitary hormone deficiency, diabetes insipidus, seizure disorder, and cerebrovascular events (CVE) due to treatment, not tumor progression, were 27%, 76%, 45%, 16%, and 11%, respectively. The CVE rate was 29% in patients who received ICB compared to 10% in those who did not (P=.07). CONCLUSIONS We report favorable PFS in patients with craniopharyngioma, especially in those who received RT after surgery. DSS and OS rates were excellent regardless of primary treatment modality. We observed a high incidence of hypopituitarism, visual deterioration, and seizure disorder. Eleven percent of patients experienced CVEs after treatment. There was a suggestion of increased CVE risk in patients treated with ICB.

Access to Medical and Supportive Care for Rural and Remote Cancer Survivors in Northern British Columbia

BACKGROUND Rural cancer survivors (RCS) potentially have unique medical and supportive care experiences when they return to their communities posttreatment because of the availability and accessibility of health services. However, there is a limited understanding of cancer survivorship in rural communities. PURPOSE The purpose of this study is to describe RCS experiences accessing medical and supportive care postcancer treatment. METHODS Interviews and focus groups were conducted with 52 RCS residing in northern British Columbia, Canada. The data were analyzed using qualitative content analysis methods. RESULTS General Population RCS and First Nations RCS experienced challenges accessing timely medical care close to home, resulting in unmet medical needs. Emotional support services were rarely available, and, if they did exist, were difficult to access or not tailored to cancer survivors. Travel and distance were barriers to medical and psychological support and services, not only in terms of the cost of travel, but also the toll this took on family members. Many of the RCS lacked access to trusted and useful information. Financial assistance, for follow-up care and rehabilitation services, was rarely available, as was appropriate employment assistance. CONCLUSION Medical and supportive care can be inaccessible, unavailable, and unaffordable for cancer survivors living in rural northern communities.

A Supportive-Educational Intervention for Heart Failure Patients in Iran: The Effect on Self-Care Behaviours

Background. Chronic heart failure is a major health and social problem. The promotion of self-care behaviours can potentially assist patients to effectively manage this chronic condition and prevent worsening of the disease. Formal personalized educational interventions that provide support and take into consideration the cultural context are needed. Objective. The objective of this research was to evaluate the effect of a supportive-educational intervention on self-care behaviours of heart failure patients in Iran. Methods. This research was a prospective, randomized trial of a supportive-educational intervention. Eighty heart failure patients were randomly assigned to receive the supportive-educational intervention or usual care. The intervention consisted of a one-hour, nurse-led, in-person education session and postdischarge followup by telephone over three months. Data were collected at baseline, one, two, and three months. Results. The control and intervention groups did not differ in self-care scores at baseline (P > 0.05). Each of the self-care scores was significantly higher in the intervention group than the control group at 1, 2, and 3 months (P < 0.001). There were significant differences in self-care behaviours over the three months, among participants in the intervention group. Conclusion. This study provides support for the effectiveness of a supportive-educational intervention to increase self-care behaviours among Iranian patients suffering from chronic heart failure.

Investigating the Perceived Feasibility of Integrative Medicine in a Conventional Oncology Setting Yoga Therapy as a Treatment for Breast Cancer Survivors

Background. A majority of cancer survivors experience debilitating effect(s) related to their cancer diagnosis and treatments across physical, psychological, social, and spiritual domains. Timely and innovative solutions are needed to address the adverse treatment-related effects and often disjointed services that breast cancer patients face. Recent studies suggest that the majority of breast cancer survivors are using complementary and alternative medicine at some point along their cancer trajectory. In recent years, scientists and clinicians have examined the effects of yoga therapy among cancer patients and survivors. The current study examined the perceived feasibility of implementing yoga therapy as a treatment service for breast cancer patients at a large urban cancer center in Canada. Methods. A mixed-methods approach that included focus groups and self-reported surveys with health care providers (HCPs) and breast cancer patients was used in this research. Results. Overall, results indicated that breast cancer patients and HCPs were supportive and eager for the implementation of a yoga therapy program. Six themes emerged from the analysis of the focus group and the survey data: (1) the availability of resources and accessibility of yoga therapy, (2) the credibility and transparency of yoga therapy, (3) the understanding of yoga therapy, (4) an educational component, (5) the therapeutic context, and (6) the integration of yoga therapy. Specific facilitators and barriers became evident within these themes. Conclusions. Although enthusiasm for the implementation of an integrative yoga therapy program was apparent among both breast cancer survivors and HCPs, barriers were also identified. The findings of this study are currently being used to inform a large-scale program of research aimed at developing integrative treatment services for breast cancer patients, beginning with yoga therapy.

A structured approach to knowledge exchange: Understanding the implementation of a cancer survivor program

PURPOSE The purpose of this research was to describe the application of a model of knowledge exchange, the Knowledge Exchange-Decision Support (KE-DS) Model, to the Canadian pilot of Cancer Transitions, a psychosocial program for cancer survivors. METHOD We compared and contrasted the program planning and implementation processes across three diverse sites offering Cancer Transitions. The KE-DS Model guided the collection and analysis of observations and written data according to specific model components. RESULTS The use of the KE-DS Model highlighted four pertinent factors that influenced knowledge exchange during planning and implementation processes of this psychosocial program. First, the geographic diversity of where these programs were offered affected strategies for program promotion, recruitment and means of access. Second, the variation of the professional and organizational capacity of the three sites was critical to program planning and delivery. Third, cultural values and norms shaped each sites approach. Fourth, the KE-DS Model identified populations who were included and excluded from participation. CONCLUSIONS The KE-DS Model was useful in elucidating the processes of knowledge exchange during the planning and implementing of an intervention for survivor care. This process information will inform future offerings of Cancer Transitions.

Comparison of hypersensitivity rates to intravenous and intramuscular PEG-asparaginase in children with acute lymphoblastic leukemia: A meta-analysis and systematic review

Pegylated‐asparaginase (PEG‐ASP) is a critical treatment for pediatric acute lymphoblastic leukemia (ALL) and has traditionally been delivered via intramuscular (IM) injection. In an attempt to reduce pain and anxiety, PEG‐ASP has increasingly been delivered via intravenous (IV) administration. The study objective was to perform a meta‐analysis and systematic review to compare and generate pooled hypersensitivity rates for IM and IV PEG‐ASP.

Patient-reported factors associated with adherence to adjuvant endocrine therapy after breast cancer: an integrative review

BackgroundAdjuvant endocrine therapy (AET) significantly reduces recurrence and mortality in women with breast cancer (BrCa). Despite the efficacy of AET in improving BrCa outcomes, up to 50% of women do not adhere to prescribed AET regimens. While numerous demographic and clinical predictors influence adherence and persistence, few studies have identified the patient-reported factors that influence AET adherence and persistence.PurposeThe aim was to examine the patient-reported personal, social, and structural factors influencing BrCa survivors’ adherence and persistence with AET.MethodsAn integrative review was undertaken wherein PubMed, Medline, CINAHL, Embase, and PsycINFO databases were searched using keyword descriptors and database subject headings. Inclusion criteria included quantitative or qualitative peer-reviewed studies written in English that assessed AET adherence and/or persistence through objective measurement or self-report and included patient-reported factors found to influence adherence and/or persistence. The data extracted from eligible studies were entered into a matrix, and systematically compared and iteratively analyzed using relational autonomy as an organizing theoretical framework.ResultsA total of 43 manuscripts (9 qualitative and 34 quantitative) were reviewed. Several personal, social, and structural factors were identified that influenced AET adherence and persistence, including side effects, necessity beliefs, self-efficacy, the patient–healthcare provider relationship, social support, and continuity of follow-up care.ConclusionsAn increasing number of studies have focused on identifying the patient-reported factors that influence AET adherence and persistence. This review highlights important personal, social, and structural factors that act as facilitators and barriers in adhering to and persisting with long-term AET. Acknowledging and addressing these factors is key to providing women with the care needed to improve suboptimal adherence and persistence.
