Abstract
In recent decades, the possibility that use of mobile communicating devices, particularly wireless (mobile and cordless) phones, may increase brain tumour risk, has been a concern, particularly given the considerable increase in their use by young people. MOBI-Kids, a 14-country (Australia, Austria, Canada, France, Germany, Greece, India, Israel, Italy, Japan, Korea, the Netherlands, New Zealand, Spain) case-control study, was conducted to evaluate whether wireless phone use (and particularly resulting exposure to radiofrequency (RF) and extremely low frequency (ELF) electromagnetic fields (EMF)) increases risk of brain tumours in young people. Between 2010 and 2015, the study recruited 899 people with brain tumours aged 10 to 24 years old and 1,910 controls (operated for appendicitis) matched to the cases on date of diagnosis, study region and age. Participation rates were 72% for cases and 54% for controls. The mean ages of cases and controls were 16.5 and 16.6 years, respectively; 57% were males. The vast majority of study participants were wireless phones users, even in the youngest age group, and the study included substantial numbers of long-term (over 10 years) users: 22% overall, 51% in the 20-24-year-olds. Most tumours were of the neuroepithelial type (NBT; n = 671), mainly glioma. The odds ratios (OR) of NBT appeared to decrease with increasing time since start of use of wireless phones, cumulative number of calls and cumulative call time, particularly in the 15-19 years old age group. A decreasing trend in ORs was also observed with increasing estimated cumulative RF specific energy and ELF induced current density at the location of the tumour. Further analyses suggest that the large number of ORs below 1 in this study is unlikely to represent an unknown causal preventive effect of mobile phone exposure: they can be at least partially explained by differential recall by proxies and prodromal symptoms affecting phone use before diagnosis of the cases. We cannot rule out, however, residual confounding from sources we did not measure. Overall, our study provides no evidence of a causal association between wireless phone use and brain tumours in young people. However, the sources of bias summarised above prevent us from ruling out a small increased risk.

Abstract
BACKGROUND Exercise is an important therapy to improve well-being after a cancer diagnosis. Accordingly, cancer-exercise programs have been developed to enhance clinical care; however, few programs exist in Canada. Expansion of cancer-exercise programming depends on an understanding of the process of program implementation, as well as enablers and barriers to program success. Gaining knowledge from current professionals in cancer-exercise programs could serve to facilitate the necessary understanding. METHODS Key personnel from Canadian cancer-exercise programs (n = 14) participated in semistructured interviews about program development and delivery. RESULTS Content analysis revealed 13 categories and 15 subcategories, which were grouped by three organizing domains: Program Implementation, Program Enablers, and Program Barriers. ■ Program Implementation (5 categories, 8 subcategories) included Program Initiation (clinical care extension, research project expansion, program champion), Funding, Participant Intake (avenues of awareness, health and safety assessment), Active Programming (monitoring patient exercise progress, health care practitioner involvement, program composition), and Discharge and Follow-up Plan.■ Program Enablers (4 categories, 4 subcategories) included Patient Participation (personalized care, supportive network, personal control, awareness of benefits), Partnerships, Advocacy and Support, and Program Characteristics.■ Program Barriers (4 categories, 3 subcategories) included Lack of Funding, Lack of Physician Support, Deterrents to Participation (fear and shame, program location, competing interests), and Disease Progression and Treatment. CONCLUSIONS Interview results provided insight into the development and delivery of cancer-exercise programs in Canada and could be used to guide future program development and expansion in Canada.

Abstract
OBJECTIVE To systematically review the evidence of pre-operative exercise, known as 'prehabilitation', on peri- and postoperative outcomes in adult surgical populations. DESIGN Systematic review and meta-analysis. DATA SOURCES CENTRAL, Medline, EMBASE, CINAHL, PsycINFO and PEDro were searched from 1950 to 2011. METHODS Two reviewers independently examined relevant, English-language articles that examined the effects of pre-operative total-body exercise with peri- and postoperative outcome analysis. Given the nascence of this field, controlled and uncontrolled trials were included. Risk of bias was assessed using the Cochrane Risk of Bias Assessment tool. Only data on length of stay were considered eligible for meta-analysis due to the heterogeneity of measures and methodologies for assessing other outcomes. RESULTS In total, 4597 citations were identified by the search strategy, of which 21 studies were included. Trials were generally small (median=54 participants) and of moderate to poor methodological quality. Compared with standard care, the majority of studies found that total-body prehabilitation improved postoperative pain, length of stay and physical function, but it was not consistently effective in improving health-related quality of life or aerobic fitness in the studies that examined these outcomes. The meta-analysis indicated that prehabilitation reduced postoperative length of stay with a small to moderate effect size (Hedges' g=-0.39, P=0.033). Intervention-related adverse events were reported in two of 669 exercising participants. CONCLUSION The literature provides early evidence that prehabilitation may reduce length of stay and possibly provide postoperative physical benefits. Cautious interpretation of these findings is warranted given modest methodological quality and significant risk of bias.

Abstract
Quality-of-life assessments in neurooncology are becoming more relevant with the proliferation of intensive research into brain tumors and their therapy. In this review, the authors examined several aspects and problems associated with the past, present, and future applications of quality-of-life assessments in neurooncology. The inadequacy of the almost exclusive use of physical functioning assessments, image-documented tumor response to therapy, and patient survival time as endpoints when evaluating therapeutic regimens is becoming increasingly apparent. In therapies in which outcome using traditional endpoints are only marginally different, specific (neurological) toxicity and social and psychological outcomes must be evaluated as well to determine valid treatment options. Also becoming widely accepted is the consideration of patient values of specific health states in justifying treatment resources. There is ongoing research in brain tumor patients to address these issues.

Abstract
As most women diagnosed with cervical carcinoma have been "inadequately screened," improvements in screening are critical. After abnormal Pap test findings (through liquid-based cytology), residual specimens now can be tested simultaneously for oncogenic types of Human Papilloma virus (HPV). If these "reflex" HPV tests are negative, Pap tests need not be repeated for 12 months. Women with positive oncogenic HPV tests, however, can be referred immediately for colposcopy. There has been concern that "stigma" issues could be associated with positive HPV status (because of its sexual transmission) that might cause women to avoid this reflex HPV testing. We addressed this concern by assessing whether stigma issues surface in relation to HPV testing. We randomly selected 20 women and administered to them semistructured telephone interviews that included responses to a scenario of reflex HPV-DNA testing. Interview transcripts were analyzed qualitatively. Highly limited knowledge levels were found about HPV, but, following education about screening options, there was no rejection of HPV testing. In conclusion, it appears that women favor reflex HPV testing due to its "convenience" and perceptions that it is "the least intrusive option more definitive than Pap testing."

Abstract
PURPOSE To determine which formats for presenting health-related quality of life (HRQL) data are interpreted most accurately and are most preferred by cancer patients. Patients often want a great deal of information about cancer treatments, including information relevant to HRQL. Clinical trials provide methodologically sound HRQL data that may be useful to patients. PATIENTS AND METHODS In a multicenter study, 198 patients with previously treated cancer participated in a structured interview. Participants judged HRQL information presented in one textual and five graphical formats. Outcome measures included the accuracy of patients' interpretations and ease-of-use and helpfulness ratings for each format. RESULTS Correct interpretations ranged from 85% to 98% across formats (F = 10.3, P < .0001) with line graphs of mean HRQL scores over time being interpreted correctly most often. Older patients and less-educated patients were less likely to interpret graphs accurately (F = 7.3, P = .008; and F = 10.6, P = .001, respectively), but all groups were most accurate on simple line graphs. Multivariate analysis revealed that format type, participant age and education were independent predictors of accuracy rates. Patients' ratings also varied across formats both for ease of understanding scores (F = 12.1, P < .0001) and for helpfulness scores (F = 13.2, P < .0001), with line graphs being rated highest on both outcomes. CONCLUSION Patients generally prefer a simple linear representation of group mean HRQL scores, and can accurately interpret data presented in this format more than 98% of the time irrespective of their age group and educational level. The findings have important implications for the communication of clinical trial HRQL results.

Abstract
Health-related quality of life (HRQL) is a prevalent outcome measure in clinical trials, but it is not known how best to communicate HRQL results to new patients with cancer. The purpose was to explore cancer patients' attitudes toward, and preferences for, 10 visual and written formats for communicating HRQL information. Using standardized qualitative methods, six focus groups were held (two groups in each of three cancer centres) with patients who had completed treatment for cancer at least 6 months earlier. Groups were stratified according to patients' education. To ensure consistency across centres, group moderators used the same detailed guide, training video, and props. Three investigators independently coded the resulting transcripts. Participants also rated each of the 10 presentation formats as to their perceived usefulness. Fourteen men and 19 women with a variety of cancer diagnoses participated; 13 (39%) participated in the three lower-education groups and 20 (61%) in the three higher-education groups. We found that simple formats (simple graphs or written text) were generally preferred to more complex graphical information, regardless of educational level. The same format was rated favourably by the highest proportion of participants in both the high (85%) and low (85%) education level groups. Individual patients, however, varied as to which visual format they most preferred. Patients did not wish to receive HRQL information out of context or without explanation. We conclude that cancer patients desire HRQL information, but vary in their preferences for its communication. Simple formats are generally preferred.

Abstract
OBJECTIVE To evaluate whether self-report measures of psychological distress and perceived risk were associated with nonadherence to recommended ovarian cancer surveillance. METHODS Eighty-three patients attending the Familial Ovarian Cancer Clinic (FOCC) at Princess Margaret Hospital were assessed psychosocially prior to and during initial familial-genetic assessment and then monitored for adherence with recommended follow-up surveillance over a period of 12-18 months. The assessment protocol included an investigator-designed clinic questionnaire, the State-Trait Anxiety Inventory (STAI), Center for Epidemiologic Studies Depression Scale (CESD), Life Orientation Test (LOT), Medical Outcomes Study Social Support Survey (MOSSS), Texas Inventory of Grief, and the COPE. Nonadherence was measured in terms of unexplained absences at one or two recommended and scheduled surveillance appointments following the familial-genetic assessment. RESULTS Univariate tests revealed a significant association between higher perception of ovarian cancer risk, as assessed immediately after the familial-genetic risk assessment in the clinic and nonadherence to physician-recommended surveillance (chi2 (2, N = 83) = 9.75, P < 0.008). Empirically based estimates of risk, conveyed by the clinic team to subjects, were not significantly associated with nonadherence (chi2 (2, N = 83) = 0.19, P = 0.91). Logistic regression analysis revealed that subjects who perceived themselves to be at high ovarian cancer risk were five times more likely to be nonadherent than participants who perceived themselves to be at low or medium ovarian cancer risk. CONCLUSIONS These results suggest that higher self-perceived risk may predict adherence difficulties to recommended surveillance in women attending a familial-genetic risk clinic.

Abstract
OBJECTIVE Our purpose was to determine the factors involved in the cancer screening decisions of family physicians in situations where the clinical practice guidelines are unclear or conflicting as opposed to when they are clear and uncontroversial. STUDY DESIGN We analyzed discussions with focus groups using a constant comparative approach. POPULATION A total of 73 family physicians in active practice participated in 10 focus groups (1 urban group and 1 rural group in each of 5 Canadian provinces). OUTCOME MEASURES Our main outcome measures were participants' perceptions regarding cancer screening when the guidelines were unclear or conflicting. RESULTS We propose a model of the determinants of cancer screening decision making with regard to unclear and conflicting guidelines. This model is rooted in the physician-patient relationship, and is an interactive process influenced by patient factors (anxiety, expectations, and family history) and physician factors (perception of guidelines, clinical practice experience, influence of colleagues, distinction between the screening styles of specialists and family physicians, and the amount of time and financial costs involved in performing the maneuver). CONCLUSIONS Our model is unique, because it is embedded in the physician-patient relationship. Ultimately, a modified model could be used to design interventions to assist with the implementation of preventive services guidelines.

Abstract
OBJECTIVE To determine the preferred role in medical decision making of women undergoing fertility treatments and to establish whether their knowledge of treatments is adequate to inform their choices. METHODS Self-report survey of 404 women undergoing fertility treatments in 2 university hospitals and a private fertility clinic in Canada. RESULTS The women had been in fertility treatment for 2.3 +/- 2.6 years; 67.8% reported taking fertility drugs. Most (61.7%) women wanted to share knowledge equally with their doctors about possible fertility treatments. However, about half wanted to decide alone or mostly by themselves about the acceptability of treatment risks and benefits (56%), what treatments should be selected (49.8%), and when to conclude treatments (54.3%). In addition, 55.1% of the women did not know their personal eventual chances of pregnancy with fertility treatment or thought it was 50% or greater. Over half of the women (57.2%) who had taken fertility drugs were unaware of a possible link between fertility drugs and increased ovarian cancer risk. The majority of women (61.8%) who knew of this possible association reported that they learned about it from the print media. Women who knew of the association had a poor understanding of the strength of the evidence or the ability to detect or treat ovarian cancer successfully, and 88.3% thought they could reduce cancer risk by following their doctors' advice. CONCLUSIONS Despite these women's wishes to actively participate in fertility treatment decisions, they lacked the necessary information to do so meaningfully. Public health policymakers, professional and advocacy organizations, physicians, other healthcare providers, and women themselves must find ways to improve the general public's and patients' understanding about fertility treatment outcomes and risks.

Abstract
BACKGROUND Obstacles to the use of patient-controlled analgesia (PCA) by elderly surgical patients have not been well-documented. Age differences in preoperative psychological factors, postoperative pain and analgesic consumption, treatment satisfaction, and concerns regarding PCA were measured to identify factors important to effective PCA use. METHODS Preoperatively, young (mean age +/- SD, 39 +/- 9 yr; n = 45) and older (mean age +/- SD, 67 +/- 8 yr; n = 44) general surgery patients completed measures of attitudes toward and expectations of postoperative pain and PCA, psychological distress, health opinions, self-efficacy, and optimism. On the first 2 postoperative days, pain at rest and with movement and satisfaction with pain control were assessed using visual analog scales. Daily opioid intake was recorded. When PCA was discontinued, satisfaction and concerns about it were assessed. RESULTS The older patients expected less intense pain (P </= 0.003) and preferred less information about (P </= 0.02) and involvement in (P </= 0.002) health care than young patients. There were no age differences with regard to pain at rest (P </= 0.22) or with movement (P </= 0.68). The older group self-administered less opioid than the young group (P </= 0.0001) and received PCA for more days than the young group (P </= 0.004). The groups did not differ in concerns about pain relief, adverse drug effects, including opioid addiction, and equipment use or malfunction. Satisfaction with PCA was high and did not differ between the groups. CONCLUSIONS Patient-controlled analgesia use was not hindered by age differences in beliefs about postoperative pain and opioids. Younger and older patients attained comparable levels of analgesia and were equally satisfied with their pain control.

Abstract
Health status indexes, such as the EuroQol, consist of a health state classification system and a set of utility weights. Indexes measure quality of life using a 0-1 utility score. Utilities for outcomes in prostate cancer (PC) are of unique importance, but generic indexes do not represent PC outcomes (e.g., sexual, urinary, bowel dysfunction) well, and may not capture their full impact. As a step toward improved utility measurement, we constructed a classification system for PC. We generated items for each of six health domains and rated their importance using interviews with 10 clinical experts and 80 patients. Key concepts were selected for each domain using item importance weightings, and a set of predetermined criteria. Text was developed to express levels of severity within each domain. Experts and two additional groups of patients (n = 40, n = 96) evaluated textual clarity and endorsed the content validity of the instrument. The final system consists of 10 domains with 4-6 levels each. The content validity of the system was endorsed by patients and experts. In conjunction with a set of utility weights, it may be used to develop a health status index, to improve utility measurement in patients, and to serve as a short psychometric (nonutility) instrument.

Abstract
Heritable cancer risk assessment is an increasingly common method of deriving valuable information relevant to deciding on appropriate screening regimens and preventive treatments. Assessments of heritable risk typically include familial-genetic evaluation, where analyses relate family pedigree to cancer risk, and DNA testing, where analyses indicate genetic mutations associated with cancer risk (e.g., BRCA1/BRCA2 mutations) or their absence. In this paper we report on the psychological responses of women given familial-genetic evaluations for ovarian cancer risk. The baseline and 6 to 12 follow-up assessments of an initial clinic-attending cohort of 65 women are compared with the baseline and 9 to 12 follow-up assessments of a second clinic-attending cohort of 60 women. Sizeable differences were found in the prevalence of clinically significant depression in these two physician or self-referred populations, as assessed by the Center for Epidemiological Studies Depression scale and in the mean scores. Hypotheses accounting for these differences are discussed.

Abstract
The motivations of cancer patients in seeking complementary therapies are, fundamentally, self-healing motivations which, when engaged appropriately, can contribute to the patient's psychological and physical well being. In this paper, we apply a theoretical model, the Risk Adaptation Model, to furthering the clinical understanding of the motivations of cancer patients in seeking complementary therapies. The model identifies six discrete cognitive processes which, in combination, are hypothesized to play a central role in therapy seeking. Emphasis in this model is placed on the patient's need to maintain positive expectancies (optimism) when faced with the risk and uncertainty of cancer. This understanding of complementary-therapy seeking is grounded in the perspective that clinicians must respect the autonomy of cancer patients in their quest for appropriate therapies, and assist rather than direct their process of therapy-seeking.

Abstract
OBJECTIVES To evaluate the psychological adjustment of women during initial genetic ovarian cancer risk assessment and at clinic follow-up, 6-12 months later. METHODS Sixty-five subjects were assessed with the Centre for Epidemiological Studies Depression Scale (CESD), Spielberger's State Anxiety Inventory, and an 18-item, investigator-designed questionnaire yielding self-report on screening responses, worry about increased risk, identification of cancer-related deaths in relatives, worry about future cancer risks of daughters, alteration of future plans as a result of ovarian cancer risk, etc. RESULTS Thirty-three percent of subjects had CESD scores above the established cutoff for depression at baseline and 38% had scores above cutoff at follow-up. Sixteen percent of subjects had state scores on the State-Trait Anxiety Inventory higher than 1 standard deviation above average (norm) at baseline, while only 6% had scores higher than 1 SD above average at follow-up. CONCLUSION To identify factors associated with self-reported depression at follow-up, a series of demographic and self-reported variables (e.g., presence of identified problems in family, impact of genetic risk information, concern for daughter in the future) were entered in a multiple regression analysis with the CESD follow-up score as the dependent variable. Only one predictor accounted for a significant amount of variance in depression scores. Concern for daughter's risk in the future was associated with higher depression scores at follow-up (R = 0.33, P<0.02, R(2) = 11%).

Abstract
Bone marrow transplant (BMT) is a procedure used for the treatment of a variety of cancers and malignant diseases. Recovery from this intensive process requires a long-term course, often accompanied by acute morbidity which includes various distressing physical symptoms. Recent literature has begun to explore the impact of this procedure on quality of life and psychosocial issues. While survivorship is often associated with a highly rated global quality of life, recovery from BMT is accompanied by several psychosocial difficulties which negatively impact patients. Fatigue is a common complaint, often hindering recipients for several years following their transplant. As well, reports of psychological distress, psychiatric symptoms, and/or mood disturbances such as anxiety or depression are not uncommon. Many patients also indicate interruption of sexual activity and increased sexual difficulty for several months following BMT. While some investigators have begun to examine hormone replacement therapy (HRT) as a treatment option for reducing sexual dysfunction, there is a general paucity of literature evaluating interventions for BMT survivors. This article reviews the literature examining various quality of life aspects including fatigue, psychosocial difficulties, and sexual functioning of patients during recovery from BMT. Limitations of past research are discussed and directions for future research suggested.

Abstract
OBJECTIVE To determine the feasibility of asking women undergoing fertility treatment the maximum increased risk of ovarian cancer they would be willing to tolerate in order to take ovulation-induction drugs. DESIGN A prospective pilot study of women attending fertility clinics over a 2-month period. SETTING Two tertiary care fertility clinics in Toronto. PATIENT(S) Sixty-one English-speaking women were approached and 85% (n = 52) were enrolled. INTERVENTION(S) A self-administered questionnaire with fertility-specific questions. Thirty-eight women also were asked to complete standardized scales of anxiety and optimism. MAIN OUTCOME MEASURE(S) Women's report of the maximum level of lifetime risk of ovarian cancer they were willing to tolerate in order to undergo fertility treatment. RESULT(S) Seventy-nine percent were willing to accept an increased risk of ovarian cancer. Only 24% understood that treatment for ovarian cancer usually was not curative. CONCLUSION(S) A majority of patients were willing to tolerate a modest increase in their lifetime risk of ovarian cancer because of fertility treatment, most basing their estimate of acceptable risk on limited awareness of the issue.
