Identifying an accurate pre-screening tool in geriatric oncology

The use of comprehensive geriatric assessment (CGA) in cancer patients older than 70 is recommended. Three pre-screening instruments have been proposed: the abbreviated comprehensive geriatric assessment (aCGA), the Vulnerable Elders Survey (VES-13), and the Groningen frailty index (GFI). The objective of the study was to identify the most efficient pre-screening tool that accurately determines individuals who may benefit from the entire CGA. A total of 113 elderly cancer patients were assessed by means of the aCGA, VES-13, GFI and the full CGA. The sensitivity, specificity of the three instruments was calculated, using the results from the entire CGA as the gold standard for the GFI and the VES-13. The aCGA was assessed whether each sub-component reliably predicts impairment on each sub-component of the full CGA. The majority of the participants were defined as being at risk of vulnerability: 68.14% had two or more impairments of the CGA or were cognitively impaired. The physical and disability questions are useful, but all other screening instruments miss too many cases.

Prognostic value of handgrip strength in people aged 60 years and older: A systematic review and meta‐analysis

The aim of the present study was to systematically review the literature on the predictive value of handgrip strength as a marker for vulnerability. Furthermore, we aimed to update a recent systematic review on the association between handgrip strength and mortality.

The relation between depression, coping and health locus of control: differences between older and younger patients, with and without cancer.

Depression is an important health issue in cancer patients. People use different coping strategies and health locus of control to manage stressful situations, which relate to different risks of depression. Coping strategies and health locus of control can be changed by cognitive behavioral interventions.

Risk factors for loneliness in patients with cancer: A systematic literature review and meta-analysis

OBJECTIVE To systematically review the literature on the severity and risk factors for loneliness in adult cancer patients. METHODS We systematically reviewed quantitative studies addressing loneliness in cancer patients. Exclusion criteria were absence of a validated loneliness questionnaire, and studies that focused on loneliness determined by specific circumstances, and not cancer in general (e.g. appearance concerns, cultural and language barriers, requiring palliative care). We searched PsycINFO, CINAHL, Embase, Cochrane Library, and Pubmed in compliance with the predefined in- and exclusion criteria. The search, quality appraisal, and data extraction were performed by two independent reviewers. Weighted mean scores were calculated by using random effects adjusted inverse variance weighting. RESULTS We included 15 studies. In 13 studies the UCLA loneliness scale was used (range 20-80; higher scores indicate higher loneliness). The weighted mean loneliness score was 38.26 (95% CI: 35.51-41.00), which corresponds to moderate loneliness. Time since diagnosis was positively associated with degree of loneliness. Other cancer-related factors, such as cancer site, treatment type, or stage of disease were not associated with loneliness. The non-cancer related determinants of loneliness in cancer patients that emerged from our review were being unmarried (people who have never been married, are widowed or divorced), and lack of psychological or social support. CONCLUSION Our findings suggest that the level of loneliness rises with increasing time after cancer diagnosis. Furthermore, social functioning emerged as a consistent theme, for which it was shown that lack of social support was associated with increasing levels of loneliness.

Chronic Diseases among Older Cancer Survivors

Objective. To compare the occurrence of pre-existing and subsequent comorbidity among older cancer patients (≥60 years) with older non-cancer patients. Material and Methods. Each cancer patient (n = 3835, mean age 72) was matched with four non-cancer patients in terms of age, sex, and practice. The occurrence of chronic diseases was assessed cross-sectionally (lifetime prevalence at time of diagnosis) and longitudinally (incidence after diagnosis) for all cancer patients and for breast, prostate, and colorectal cancer patients separately. Cancer and non-cancer patients were compared using logistic and Cox regression analysis. Results. The occurrence of the most common pre-existing and incident chronic diseases was largely similar in cancer and non-cancer patients, except for pre-existing COPD (OR 1.21, 95% CI 1.06–1.37) and subsequent venous thrombosis in the first two years after cancer diagnosis (HR 4.20, 95% CI 2.74–6.44), which were significantly more frequent (P < 0.01) among older cancer compared to non-cancer patients. Conclusion. The frequency of multimorbidity in older cancer patients is high. However, apart from COPD and venous thrombosis, the incidence of chronic diseases in older cancer patients is similar compared to non-cancer patients of the same age, sex, and practice.

Prognostic value of circulating cytokines on overall survival and disease-free survival in cancer patients

Through their tumor-promoting and/or tumor-suppressive properties, cytokines can influence progression of cancer. We systematically reviewed the current literature on the prognostic value of the circulating cytokines IL-1α/β, IL-6, IL-8, IL-10, IL-12, TNF-α, TGF-β and IFN-γ to predict overall and disease-free survival in any type of cancer patients. PubMed was systematically searched and based on eligibility assessment using our five criteria of the Reporting Recommendations for Tumor Marker Prognostic Studies (REMARK) checklist, six unique studies were reviewed. Elevated IL-6 and IL-10 levels seem independently associated with worse prognosis in terms of overall and disease-free survival. The prognostic value of IL-1α/β, IL-8, IL-12, TNF-α, TGF-β and IFN-γ could not be demonstrated. The small number of selected studies underlines the need for large well-designed prospective studies, using the REMARK checklist as a guideline, to determine which cytokines have prognostic value on survival in cancer patients.

Study protocol of KLIMOP: a cohort study on the wellbeing of older cancer patients in Belgium and the Netherlands

BackgroundCancer is mainly a disease of older patients. In older cancer patients, additional endpoints such as quality of survival and daily functioning might be considered equally relevant as overall or disease free survival. However, these factors have been understudied using prospective designs focussing on older cancer patients. Therefore, this study will focus on the impact of cancer, ageing, and their interaction on the long-term wellbeing of older cancer patients.Methods/DesignThis study is an observational cohort study. We aim to recruit 720 cancer patients above 70 years with a new diagnosis of breast, prostate, lung or gastrointestinal cancer and two control groups: one control group of 720 patients above 70 years without a previous diagnosis of cancer and one control group of 720 cancer patients between 50 - 69 years newly diagnosed with breast, prostate, lung or gastrointestinal cancer. Data collection will take place at inclusion, after six months, after one year and every subsequent year until death or end of the study. Data will be collected through personal interviews (consisting of socio-demographic information, general health information, a comprehensive geriatric assessment, quality of life, health locus of control and a loneliness scale), a handgrip test, assessment of medical records, two buccal swabs and a blood sample from cancer patients (at baseline). As an annex study, caregivers of the participants will be recruited as well. Data collection for caregivers will consist of a self-administered questionnaire examining depression, coping, and burden.DiscussionThis extensive data collection will increase insight on how wellbeing of older cancer patients is affected by cancer (diagnosis and treatment), ageing, and their interaction. Results may provide new insights, which might contribute to the improvement of care for older cancer patients.

Functional status decline in older patients with breast and colorectal cancer after cancer treatment: A prospective cohort study

OBJECTIVES The aim of the present study was to disentangle the impact of age and that of cancer diagnosis and treatment on functional status (FS) decline in older patients with cancer. MATERIALS AND METHODS Patients with breast and colorectal cancer aged 50-69years and aged ≥70years who had undergone surgery, and older patients without cancer aged ≥70years were included. FS was assessed at baseline and after 12months follow-up, using the Katz index for activities of daily living (ADL) and the Lawton scale for instrumental activities of daily living (IADL). FS decline was defined as ≥1 point decrease on the ADL or IADL scale from baseline to 12months follow-up. RESULTS In total, 179 older patients with cancer (≥ 70years), 341 younger patients with cancer (50-69years) and 317 older patients without cancer (≥ 70years) were included. FS decline was found in 43.6%, 24.6% and 28.1% of the groups, respectively. FS decline was significantly worse in older compared to younger patients with cancer receiving no chemotherapy (44.5% versus 17.6%, p<0.001), but not for those who did receive chemotherapy (39.4% versus 30.8%, p=0.33). Among the patients with cancer, FS decline was significantly associated with older age (OR 2.63), female sex (OR 3.72), colorectal cancer (OR 2.81), polypharmacy (OR 2.10) and, inversely, with baseline ADL dependency (OR 0.44). CONCLUSION Cancer treatment, and older age are important predictors of FS decline. The relation of baseline ADL dependency and chemotherapy with FS decline suggest that the fittest of the older patients with cancer were selected for chemotherapy.

Changing the Antibiotic Prescribing of general practice registrars: the ChAP study protocol for a prospective controlled study of a multimodal educational intervention.

BackgroundAustralian General Practitioners (GPs) are generous prescribers of antibiotics, prompting concerns including increasing antimicrobial resistance in the community. Recent data show that GPs in vocational training have prescribing patterns comparable with the high prescribing rate of their established GP supervisors. Evidence-based guidelines consistently advise that antibiotics are not indicated for uncomplicated upper respiratory tract infections (URTI) and are rarely indicated for acute bronchitis. A number of interventions have been trialled to promote rational antibiotic prescribing by established GPs (with variable effectiveness), but the impact of such interventions in a training setting is unclear. We hypothesise that intervening while early-career GPs are still developing their practice patterns and prescribing habits will result in better adherence to evidence-based guidelines as manifested by lower antibiotic prescribing rates for URTIs and acute bronchitis.Methods/designThe intervention consists of two online modules, a face-to-face workshop for GP trainees, a face-to-face workshop for their supervisors and encouragement for the trainee-supervisor dyad to include a case-based discussion of evidence-based antibiotic prescribing in their weekly one-on-one teaching meetings.We will use a non-randomised, non-equivalent control group design to assess the impact on antibiotic prescribing for acute upper respiratory infections and acute bronchitis by GP trainees in vocational training.DiscussionEarly-career GPs who are still developing their clinical practice and prescribing habits are an underutilized target-group for interventions to curb the growth of antimicrobial resistance in the community. Interventions that are embedded into existing training programs or are linked to continuing professional development have potential to increase the impact of existing interventions at limited additional cost.Trial registrationAustralian New Zealand Clinical Trials Registry, ACTRN12614001209684 (registered 17/11/2014).

Loneliness in patients with cancer: the first year after cancer diagnosis.

We studied the frequency and evolution of social and emotional loneliness in older cancer patients in comparison with younger cancer patients and older people without cancer. We evaluated if changes in common cancer‐related and ageing‐related problems such as fatigue, cognitive functioning and functional status contributed to the occurrence of loneliness.
