Objective
More people are living with the consequences of cancer and comorbidity. We describe frequencies of comorbidities in a colorectal cancer cohort and associations with health and well‐being outcomes up to 5 years following surgery.Methods
Prospective cohort study of 872 colorectal cancer patients recruited 2010 to 2012 from 29 UK centres, awaiting curative intent surgery. Questionnaires administered at baseline (pre‐surgery), 3, 9, 15, 24 months, and annually up to 5 years. Comorbidities (and whether they limit activities) were self‐reported by participants from 3 months. The EORTC QLQ‐C30 and QLQ‐CR29 assessed global health/quality of life (QoL), symptoms, and functioning. Longitudinal analyses investigated associations between comorbidities and health and well‐being outcomes.Results
At baseline, the mean age of participants was 68 years, with 60% male and 65% colon cancer. Thirty‐two per cent had 1 and 40% had ≥2 comorbidities. The most common comorbidities were high blood pressure (43%), arthritis/rheumatism (32%), and anxiety/depression (18%). Of those with comorbidities, 37% reported at least 1 that limited their daily activities. Reporting any limiting comorbidities was associated with poorer global health/QoL, worse symptoms, and poorer functioning on all domains over 5‐year follow‐up. Controlling for the most common individual comorbidities, depression/anxiety had the greatest deleterious effect on outcomes.Conclusions
Clinical assessment should prioritise patient‐reported comorbidities and whether these comorbidities limit daily activities, as important determinants of recovery of QoL, symptoms, and functioning following colorectal cancer. Targeted interventions and support services, including multiprofessional management and tailored assessment and follow‐up, may aid recovery of health and well‐being in these individuals.2.

Objective
Why some people recover emotionally after diagnosis and treatment of cancer and others do not is poorly understood. To identify factors around the time of diagnosis that predict longer‐term distress is a necessary step in developing interventions to reduce patients' vulnerability. This review identified the demographic, clinical, social, and psychological factors available at or within 3 months of diagnosis that are reliable predictors of emotional distress at least 12 months later.Methods
A systematic search of literature for prospective studies addressing our research question and predicting a range of distress outcomes was conducted. Thirty‐nine papers (reporting 36 studies) were subjected to narrative synthesis of the evidence.Results
There was no consistent evidence that demographic, clinical, or social factors reliably predicted longer‐term distress. Of the psychological factors examined, only baseline distress (significant in 26 of 30 relevant papers; 24 of 28 studies) and neuroticism (significant in all 5 papers/studies that examined it) consistently predicted longer‐term distress. The heterogeneity of included studies, particularly in populations studied and methodology, precluded meta‐analytic techniques.Conclusions
This review supports current clinical guidance advising early assessment of distress as a marker of vulnerability to persistent problems. Additionally, neuroticism is also indicated as a useful marker of vulnerability. However, the review also highlights that more sophisticated research designs, capable of identifying the psychological processes that underlie the association between these marker variables and persistent distress, are needed before more effective early interventions can be developed.3.

Objective
This study explored help‐seeking behaviours, group identification, and perceived legitimacy of discrimination, and its potential relationship with perceived lung cancer stigma.Methods
Consecutive consenting adults (n = 274) with a primary diagnosis of lung cancer within the previous 4 months were recruited at 31 outpatient clinics in Australia. A self‐report survey assessed help‐seeking, group identification, perceived legitimacy of discrimination, and perceived lung cancer stigma.Results
Services providing assistance from health professionals (69.5%) and informational support (68.5%) were more frequently used than emotional‐based support. Only a small proportion (2.6%) of participants were unlikely to seek help from anyone, with the most popular sources of help being the general practitioner (91.0%), and oncologist/treating clinician (81.3%). One‐fifth (21.1%) indicated they identified with being a lung cancer patient, and most did not perceive discrimination against lung cancer patients. Higher perceived lung cancer stigma was significantly associated with greater perceived legitimacy of discrimination (P < 0.001), but not help‐seeking behaviours or group identification.Conclusions
The relationship between lung cancer stigma and perceived legitimacy of discrimination may guide initiatives to reduce stigma for patients. It is encouraging that perceived stigma did not appear to inhibit help‐seeking behaviours. However, further research in this emerging field is needed to investigate patterns of perceived stigma and help‐seeking over time to identify how and when to offer support services most appropriate to the needs of lung cancer patients.4.

Objective
Patients and partners both cope individually and as a dyad with challenges related to a breast cancer diagnosis. The objective of this study was to evaluate the effect of a psychological attachment‐oriented couple intervention for breast cancer patients and partners in the early treatment phase.Methods
A randomised controlled trial including 198 recently diagnosed breast cancer patients and their partners. Couples were randomised to the Hand in Hand (HiH) intervention in addition to usual care or to usual care only. Self‐report assessments were conducted for both patients and partners at baseline, postintervention (5 months), and follow‐up (10 months), assessing cancer‐related distress, symptoms of anxiety and depression, and dyadic adjustment. Patients' cancer‐related distress was the primary outcome.Results
Cancer‐related distress decreased over time in both patients and partners, but the intervention did not significantly affect this decrease at postintervention (P = .08) or follow‐up (P = .71). A significant positive effect was found on dyadic adjustment at follow‐up for both patients (P = .04) and partners (P = .02).Conclusions
There was no significant effect of the HiH intervention cancer‐related distress. The results suggest that most couples can cope with cancer‐related distress in the context of usual care. However, the positive effect on dyadic adjustment implies that the HiH intervention benefitted both patients and partners. Future studies should investigate how to integrate a couple focus in usual cancer care to improve dyadic coping in the early treatment phase.6.

Objective
Distress screening programs aim to ensure appropriate psychooncological support for cancer patients, but many eligible patients do not use these services. To improve distress management, we need to better understand patients' supportive care needs. In this paper, we report the first key finding from a longitudinal study that focused on patients' intentions to use psychooncological support and its association with distress and uptake of the psychooncology service.Methods
We conducted a prospective, observational study in an Oncology Outpatient Clinic and assessed distress, intention to use psychooncological support, and uptake of the psychooncology service by using the Distress Thermometer, a semistructured interview, and hospital records. We analyzed data with a mixed‐methods approach.Results
Of 333 patients (mean age 61 years; 55% male; 54% Distress Thermometer ≥ 5), 25% intended to use the psychooncology service (yes), 33% were ambivalent (maybe), and 42% reported no intention (no). Overall, 23% had attended the psychooncology service 4 months later. Ambivalent patients reported higher distress than patients with no intention (odds ratio = 1.18, 95% confidence interval [1.06‐1.32]) but showed significantly lower uptake behavior than patients with an intention (odds ratio = 14.04, 95% confidence interval [6.74‐29.24]). Qualitative analyses revealed that ambivalent patients (maybe) emphasized fears and uncertainties, while patients with clear intentions (yes/no) emphasized knowledge, attitudes, and coping concepts.Conclusions
We identified a vulnerable group of ambivalent patients with high distress levels and low uptake behavior. To optimize distress screening programs, we suggest addressing and discussing patients' supportive care needs in routine clinical practice.7.

Objective
In this retrospective investigation of patient pathways to psycho‐oncological treatment (POT), we compared the number of POT referrals before and after implementation of electronic screening for POT needs and investigated psychosocial predictors for POT wish at a nuclear medicine department.Methods
We extracted medical chart information about number of referrals and extent of follow‐up contacts. During standard referral (November 2014 to October 2015), POT needs were identified by clinical staff only. In the screening‐assisted referral period (November 2015 to October 2016), identification was supported by electronic screening for POT needs. Psychosocial predictors for POT wish were examined using logistic regression.Results
We analysed data from 487 patients during standard referral (mean age 56.4 years; 60.2% female, 88.7% thyroid carcinoma or neuroendocrine tumours) of which 28 patients (5.7%) were referred for POT. Of 502 patients in the screening‐assisted referral period (mean age 57.0 years; 55.8% female, 86.6% thyroid carcinoma or neuroendocrine tumours), 69 (13.7%) were referred for POT. Of these, 36 were identified by psycho‐oncological (PO) screening and 33 by clinical staff. After PO‐screening implementation, referrals increased by a factor of 2.4. The strongest predictor of POT wish was depressive mood (P < .001). During both referral periods, about 15% of patients visited the PO outpatient unit additionally to inpatient PO consultations.Conclusions
Our results provide evidence from a real‐life setting that PO screening can foster POT referrals, reduce barriers to express the POT wish, and hence help to meet psychosocial needs of this specific patient group. Differences between patients' needs, wish, and POT uptake should be further investigated.8.

Objective
The Therapeutic Practices for Distress Management (TPDM) project was carried out to support clinicians in integrating recommendations from four clinical practice guidelines (CPGs) in routine care at five Pan Canadian cancer care sites.Methods
Using a concurrent, mixed‐method study design and knowledge translation (KT) activities, this project included two phases: phase I—a baseline/preparation phase and phase II—an intervention phase plus evaluation. The intervention phase (the focus of this report) included a one‐year education and supervision program (24 hours in virtual class; 12‐hour group supervision). Primary outcomes were knowledge and self‐efficacy in practicing CPGs as measured by a Knowledge and Self‐Efficacy Survey (KSES). A secondary outcome was observer‐rated performances with standardized patients (objective structured clinical exams). Participants included 80 (90%) nurses, and 9 (10%) social workers (N = 89).Results
The TPDM program was effective in accomplishing change in knowledge, self‐efficacy, and performance. All measures demonstrated significant change pre and post module, with evidence of increasing knowledge (P < .01) and confidence (P < .01) over time. Further, there was evidence of a shift in barriers and enablers to practicing in alignment with the CPGs.Conclusions
A tailored education program using case‐based learning and supervision over time improves knowledge and practice among front line clinicians. The findings have implications for quality improvement in cancer care.9.

Objective
Despite the physical and psychological health benefits associated with physical activity (PA) for breast cancer (BC) survivors, up to 70% of female BC survivors are not meeting minimum recommended PA guidelines. The objective of this study was to evaluate acceptability and satisfaction with Project MOVE, an innovative approach to increase PA among BC survivors through the combination of microgrants and financial incentives.Methods
A mixed‐methods design was used. Participants were BC survivors and support individuals with a mean age of 58.5 years. At 6‐month follow‐up, participants completed a program evaluation questionnaire (n = 72) and participated in focus groups (n = 52) to explore their experience with Project MOVE.Results
Participants reported that they were satisfied with Project MOVE (86.6%) and that the program was appropriate for BC survivors (96.3%). Four main themes emerged from focus groups: (1) acceptability and satisfaction of Project MOVE, detailing the value of the model in developing tailored group‐base PA programs; (2) the importance of Project MOVE leaders, highlighting the value of a leader that was organized and a good communicator; (3) breaking down barriers with Project MOVE, describing how the program helped to address common BC related barriers; and (4) motivation to MOVE, outlining how the microgrants enabled survivors to be active, while the financial incentive motivated them to increase and maintain their PA.Conclusion
The findings provide support for the acceptability of Project MOVE as a strategy for increasing PA among BC survivors.10.

Objective
Depression is common among patients diagnosed with cancer. Patients with cancer and depression use more health care services compared with nondepressed cancer patients. The current study seeks to estimate the added cost of depression in cancer patients in the first year after cancer diagnosis.Methods
Health care charges were obtained for 2051 depressed and 11 182 nondepressed patients with an International Classification of Diseases, Ninth Revision, diagnosis of cancer in the 2014 calendar year from the University of California San Diego Healthcare System. The annual health care charges for cancer patients with and without depression were analyzed using generalized linear models with a log‐link function and gamma distribution, covarying for age, sex, race/ethnicity, comorbid diseases, and presence of metastatic disease. Total cost data were broken down into several categories including ambulatory care, emergency department visits, and hospital visits.Results
Depressed cancer patients had total annual health care charges that were 113% higher than nondepressed cancer patients (B = 0.76; P < .001). The estimated mean charges for depressed patients were $235 337 compared with $110 650 for nondepressed patients. Depressed cancer patients incurred greater charges than nondepressed patients in ambulatory care (B = 0.70; P < .001), emergency department charges (B = 0.31; P < .001), and hospital charges (B = 0.39; P < .001).Conclusions
Depressed cancer patients incur significantly higher health care charges across multiple cost categories including ambulatory care, emergency department visits, and hospital visits. Future research should investigate if interventions for detecting and treating depression are effective for reducing health care use and costs in cancer patients.11.

Objective
Cancer is still widely feared and often associated with death. Fatalistic beliefs adversely affect help‐seeking for cancer symptoms and engagement in cancer prevention. This study aims to understand middle‐aged and older adults' first association with the word “cancer” and their relationship with sociodemographic factors, cancer fear, and cancer information avoidance.Methods
We conducted a cross‐sectional survey of 1464 community‐based adults aged 50 to 70 living in England in April 2015. First associations with cancer were measured qualitatively and analysed using content analysis. We used binary logistic regression to analyse associations between the most common first association of cancer and sociodemographic characteristics, cancer fear, and cancer information avoidance.Results
Cancer was most commonly associated with “death” (26%). Respondents with lower levels of education, living in the Midlands or North of England where cancer mortality is higher, or with close friends or family members with a cancer history, were more likely to associate cancer with death. Cancer fear was significantly associated with death associations, but cancer information avoidance was not.Conclusions
Despite improved cancer outcomes, middle‐aged and older adults often associate cancer with death. Further efforts to decrease fatalistic associations in this age group may be needed.12.

Objective
This study examined the course and predictors of supportive care needs among Mexican breast cancer patients for different cancer treatment trajectories.Methods
Data from 172 (66.4% response rate) patients were considered in this observational longitudinal study. Participants were measured after diagnosis, neoadjuvant treatment, surgery, adjuvant treatment, and the first post‐treatment follow‐up visit. Psychological, Health System and Information, Physical and Daily Living, Patient Care and Support, Sexual, and Additional care needs were measured with the Supportive Care Needs Survey (SCNS‐SF34). Linear mixed models with maximum‐likelihood estimation were computed.Results
The course of supportive care needs was similar across the different cancer treatment trajectories. Supportive care needs declined significantly from diagnosis to the first post‐treatment follow‐up visit. Health System and Information care needs were the highest needs over time. Depressive symptoms and time since diagnosis were the most consistent predictors of changes in course of supportive care needs of these patients.Conclusions
Health system and information care needs of Mexican breast cancer patients need to be addressed with priority because these needs are the least met. Furthermore, patients with high depressive symptoms at the start of the disease trajectory have greater needs for supportive care throughout the disease trajectory.14.

Objective
Informal carers experience a variety of information and support needs when providing care to someone with cancer. It is unclear when carers seek information and what resources they access to support themselves throughout the cancer trajectory.Methods
A sample of 45 carers and 15 oncology nurses were recruited to participate in either focus groups or phone interviews.Results
Carers in the study were more likely to be women (60%), caring for a spouse or partner (64.4%), living with the patient (86.7%), and hold a university degree (46.7%). The majority of oncology nurses were females (66.6%). Findings showed that carers had limited access to adequate information as needs arose. Supports used to address information needs included information booklets, the Internet, and communication with healthcare professionals or with other carers. Barriers in communication between nurses and carers impacted on the adequacy of information received. Participants reported that technology, such as smartphone applications, might be appropriate for improving information and support needs .Conclusions
Caring for someone with cancer is multifaceted. Carers need access to timely information to help them effectively manage patients' needs. Future studies should assess the role of contemporary approaches, such as digital technology, as a solution to the delivery of information and support for carers of people with cancer.15.

Objective
According to the precaution adoption process model, cervical screening nonparticipants represent a heterogeneous group including those who are unaware of, unengaged with, or undecided about screening, as well as intenders and decliners. We aimed to explore beliefs about cervical screening among these different types of nonparticipant.Methods
Semistructured interviews were carried out with women aged 26 to 65 years living in Britain (n = 29). Women were purposively sampled to represent different nonparticipant types. Interviews were transcribed verbatim, and data were analysed thematically using framework analysis.Results
The salience of some barriers to screening varied between different types of nonparticipant. Bad experiences were prominent in the discussions of women who had decided not to attend, while practical barriers were more prominent among intenders. There was also some overlap between nonparticipant types. For example, many of the undecided women described not wanting to go for screening, but with less certainty than decliners. Some intenders (particularly those who had not been screened before) described not really wanting to attend but feeling they ought to. Women's views on the invitation/reminder process also varied; intenders and maintainers appreciated written reminders and general practitioner (GP) prompts but decliners sometimes perceived these as “badgering.” Throughout the interviews, women described changing views on screening in the wider context of ageing and motherhood.Conclusions
The salience of screening barriers varies by nonparticipant type, offering possibilities for tailored interventions. However, the fluidity of women's stage of screening adoption might have implications for this approach to intervention design.16.

Objective
This individual patient data (IPD) meta‐analysis aimed to evaluate the effects of psychosocial interventions (PSI) on quality of life (QoL), emotional function (EF), and social function (SF) in patients with cancer, and to study moderator effects of demographic, clinical, personal, and intervention‐related characteristics.Methods
Relevant studies were identified via literature searches in 4 databases. We pooled IPD from 22 (n = 4217) of 61 eligible randomized controlled trials. Linear mixed‐effect model analyses were used to study intervention effects on the post‐intervention values of QoL, EF, and SF (z‐scores), adjusting for baseline values, age, and cancer type. We studied moderator effects by testing interactions with the intervention for demographic, clinical, personal, and intervention‐related characteristics, and conducted subsequent stratified analyses for significant moderator variables.Results: PSI significantly improved QoL (β = 0.14,95%CI = 0.06;0.21), EF (β = 0.13,95%CI = 0.05;0.20), and SF (β = 0.10,95%CI = 0.03;0.18). Significant differences in effects of different types of PSI were found, with largest effects of psychotherapy. The effects of coping skills training were moderated by age, treatment type, and targeted interventions. Effects of psychotherapy on EF may be moderated by cancer type, but these analyses were based on 2 randomized controlled trials with small sample sizes of some cancer types.Conclusions
PSI significantly improved QoL, EF, and SF, with small overall effects. However, the effects differed by several demographic, clinical, personal, and intervention‐related characteristics. Our study highlights the beneficial effects of coping skills training in patients treated with chemotherapy, the importance of targeted interventions, and the need of developing interventions tailored to the specific needs of elderly patients.17.

Objective
Exercise interventions benefit cancer patients. However, only low numbers of patients adhere to these interventions. This review aimed to identify predictors of exercise intervention adherence in patients with cancer, during and after multimodality cancer treatment.Methods
A literature search was performed using electronic databases (PubMed, Embase, and Cochrane) to identify relevant papers published before February 1, 2017. Papers reporting randomized controlled trials, conducted in adult cancer patients who participated in an exercise intervention during and/or after multimodality cancer treatment, and providing outcome of factors predicting exercise adherence were included. Papers were assessed for methodological quality by using the Physiotherapy Evidence Database scale.Results
The search identified 720 potentially relevant papers, of which 15 fulfilled the eligibility criteria. In these 15 studies, 2279 patients were included and 1383 of these patients were randomized to an exercise intervention. During cancer treatment, the factors predicting exercise adherence were as follows: location of the rehabilitation center, extensive exercise history, high motivation for exercise, and fewer exercise limitations. After cancer treatment, factors that predicted adherence were as follows: less extensive surgery, low alcohol consumption, high previous exercise adherence, family support, feedback by trainers, and knowledge and skills of exercise. Methodological quality of the included papers was rated “high”.Conclusions
The most prominent predictors of adherence to exercise interventions were location of the rehabilitation center, extensive exercise history, high motivation for exercise, and fewer exercise limitations. To increase the number of cancer patients who will benefit, these results should be considered into the development and implementation of future exercise interventions.18.

Background and Objectives
To examine association of lympho‐vascular space invasion (LVSI) with clinico‐pathological factors and to evaluate survival of women with low‐grade serous ovarian carcinoma containing areas of LVSI.Methods
This is a multicenter retrospective study examining consecutive cases of surgically treated stage I‐IV low‐grade serous ovarian carcinoma (n = 178). Archived histopathology slides for the ovarian tumors were reviewed, and LVSI was scored as present or absent. LVSI status was correlated to clinico‐pathological findings and survival outcome.Results
LVSI was seen in 79 cases (44.4%, 95% confidence interval [CI] 37.1‐51.7). LVSI was associated with increased risk of omental metastasis (87.0% vs 64.9%, odds ratio [OR] 3.62, P = 0.001), high pelvic lymph node ratio (median 12.9% vs 0%, P = 0.012), and malignant ascites (49.3% vs 32.6%, OR 2.01, P = 0.035). On multivariable analysis, controlling for age, stage, and cytoreductive status, presence of LVSI in the ovarian tumor remained an independent predictor for decreased progression‐free survival (5‐year rates 21.0% vs 35.7%, adjusted‐hazard ratio 1.57, 95%CI 1.06‐2.34, P = 0.026). LVSI was significantly associated with increased risk of recurrence in lymph nodes (OR 2.62, 95%CI 1.08‐6.35, P = 0.047).Conclusion
LVSI in the ovarian tumor is associated with adverse clinico‐pathological characteristics and decreased progression‐free survival in women with low‐grade serous ovarian carcinoma.19.
A retrospective cost analysis of angioplasty compared to bypass surgery for lower limb arterial disease in an Australian tertiary health service 下载免费PDF全文

Introduction
Percutaneous transluminal angioplasty (PTA) and surgical bypass (BYP) are treatment options for symptomatic peripheral arterial disease (PAD). PTA and BYP have different clinical outcomes and cost implications. This paper aims to compare hospital‐related costs of PTA and BYP for PAD of the lower limbs in an Australian health service.Methods
A retrospective cost analysis using clinical and financial data from an urban, tertiary hospital was performed. Patient cohorts were matched to existing published studies and 3‐year findings were calculated. Outcomes measured were mean initial admission cost; mean bed stay; mean complication rate; mean cost of re‐intervention at 12 months and extrapolated mean cost at 3 years.Results
The mean total admission costs for PTA compared to BYP were $8758 vs. $27,849 (P < 0.001). Patients undergoing BYP were admitted for 10.25 vs. 3.77 nights (P < 0.001). The complication rate was greater in the BYP group for infection only. Re‐intervention was required by 13% of the PTA group and 16% of the BYP group, at a mean cost of $11,798 and $14,728, respectively (P = 0.453). The extrapolated total mean cost at 3 years was higher in the BYP group for patients with both intermittent claudication ($26,764 vs. $11,402) and critical limb ischaemia ($27,719 vs. $12,655).Conclusions
In this cohort, PTA is a favourable alternative to BYP for PAD of the lower limbs as it is less costly, does not result in a greater re‐intervention rate at 1 year and has been previously demonstrated to have comparable clinical outcomes. Given the limitations of this retrospective analysis, a prospective cost‐effectiveness analysis is recommended.20.
