Determinants of overall quality of life in preterminal cancer patients.

Recently, a few studies reported that fatigue was a predominant contributor to patient‐perceived overall QoL in patients with different types of cancer in a relatively early stage of disease. In the present study, we aimed to investigate whether fatigue is also a major contributor to overall QoL in preterminal cancer patients. Ninety‐eight preterminal cancer patients, mainly lung (44%) and gastrointestinal cancer (25%), with an estimated life expectancy of 1–6 months were included. QoL domains as well as overall QoL were measured using the EORTC QLQ‐C30 questionnaire. Data were analysed by Pearsons correlations and multivariate modelling. Fatigue showed the strongest correlation with overall QoL (r = −0.63, p < 0.001), followed in decreasing order by role functioning (r = 0.53), physical functioning (r = 0.47), social functioning (r = 0.44), nausea (r = −0.37), cognitive functioning (r = 0.33), appetite loss (r = −0.31), dyspnea (r = −0.26) and emotional functioning (r = 0.24). Multivariate analysis confirmed that the fatigue scale paid by far the highest individual contribution to overall QoL (standardized regression coefficient (SRC): −0.41, p = 0.002), followed by social functioning (SRC: 0.18, p = 0.05). None of the other domains or symptom scales contributed independently to overall QoL. Our results clearly demonstrate that, in preterminal cancer patients, fatigue is a major contributor of overall QoL, corroborating reports in cancer patients in earlier disease stages.

Effect of adenosine 5'-triphosphate infusions on the nutritional status and survival of preterminal cancer patients.

The aim of the study was to investigate the effect of intravenous infusions of adenosine 5′-triphosphate (ATP) on nutritional status and survival in preterminal cancer patients. Ninety-nine preterminal cancer patients (estimated life expectancy 1–6 months) with mixed tumor types were randomly allocated to receive either intravenous ATP weekly (8–10 h/week, maximum 50 μg/kg/min) for 8 weeks, or no ATP (control group). Nutritional status parameters were assessed until 8 weeks, and analyzed by repeated-measures analysis of covariance. Cox proportional hazards models were fitted to assess the effect of ATP on short-term (0–8 weeks) and long-term (0–6 months) survival. Fifty-one patients were randomized to ATP and 48 to the control group. Results showed a significant favorable effect of ATP on triceps skin fold thickness [between-group difference per 8 weeks 1.76 mm, 95% confidence interval (CI): 0.48–3.12 mm; P = 0.009] and on short-term survival [0–8 weeks hazard ratio (HR): 0.40, 95% CI: 0.17–0.95; P = 0.037]. In weight-stable patients and in lung cancer patients, long-term survival (0–6 months) was also significantly better in ATP-treated patients (weight-stable patients HR: 0.40, 95% CI: 0.19–0.83; P = 0.014; patients with lung cancer: HR: 0.35, 95% CI: 0.14–0.88; P = 0.025). In conclusion, in this population of preterminal cancer patients, ATP infusions, at the dose and schedule studied, had a favorable effect on triceps skin fold thickness and survival, especially in weight-stable patients and patients with lung cancer. Larger studies are warranted to confirm these findings and to further define the effect of ATP on tumor growth and survival.

Adherence to the World Cancer Research Fund/American Institute for Cancer Research lifestyle recommendations in colorectal cancer survivors: results of the PROFILES registry

We examined adherence to the eight The World Cancer Research Foundation/American Institute for Cancer Research (WCRF/AICR) recommendations on diet, physical activity, and body weight among colorectal cancer survivors, and whether adherence was associated with intention to eat healthy and with the need for dietary advice. Adherence to these recommendations may putatively reduce the risk of recurrence and death. Studies on adherence to these recommendations in colorectal cancer (CRC) survivors are lacking. Adherence was assessed in a cross‐sectional study among 1196 CRC survivors and could range between 0 (no adherence) and 8 points (complete adherence). Participants completed questionnaires on dietary intake, physical activity, and body weight. Prevalence Ratios were calculated to assess whether adherence to recommendations were associated with dietary intentions and needs. Twelve percentage of the survivors adhered to 6 or more recommendations; 65% had a score between >4 and 6 points; 23% scored no more than 4 points. The recommendation for to be modest with consumption of meat showed lowest adherence: 8% adhered; whereas the recommendation not to use dietary supplements showed highest adherence (75%). 18% reported a need for dietary advice, but this was not associated with adherence to recommendations. Survivors with higher adherence reported less often that they had received dietary advice, were less likely to have the intention to eat healthier, but reported more often that they had changed their diet since diagnosis. There is ample room for improvement of lifestyle recommendations in virtually all CRC survivors. A minor part of CRC survivors expressed a need for dietary advice which was not associated with adherence to the recommendations.

Candidate Predictors of Health-Related Quality of Life of Colorectal Cancer Survivors: A Systematic Review

UNLABELLED The population of colorectal cancer (CRC) survivors is growing and many survivors experience deteriorated health-related quality of life (HRQoL) in both early and late post-treatment phases. Identification of CRC survivors at risk for HRQoL deterioration can be improved by using prediction models. However, such models are currently not available for oncology practice. As a starting point for developing prediction models of HRQoL for CRC survivors, a comprehensive overview of potential candidate HRQoL predictors is necessary. Therefore, a systematic literature review was conducted to identify candidate predictors of HRQoL of CRC survivors. Original research articles on associations of biopsychosocial factors with HRQoL of CRC survivors were searched in PubMed, Embase, and Google Scholar. Two independent reviewers assessed eligibility and selected articles for inclusion (N = 53). Strength of evidence for candidate HRQoL predictors was graded according to predefined methodological criteria. The World Health Organizations International Classification of Functioning, Disability and Health (ICF) was used to develop a biopsychosocial framework in which identified candidate HRQoL predictors were mapped across the main domains of the ICF: health condition, body structures and functions, activities, participation, and personal and environmental factors. The developed biopsychosocial ICF framework serves as a basis for selecting candidate HRQoL predictors, thereby providing conceptual guidance for developing comprehensive, evidence-based prediction models of HRQoL for CRC survivors. Such models are useful in clinical oncology practice to aid in identifying individual CRC survivors at risk for HRQoL deterioration and could also provide potential targets for a biopsychosocial intervention aimed at safeguarding the HRQoL of at-risk individuals. IMPLICATIONS FOR PRACTICE More and more people now survive a diagnosis of colorectal cancer. The quality of life of these cancer survivors is threatened by health problems persisting for years after diagnosis and treatment. Early identification of survivors at risk of experiencing low quality of life in the future is thus important for taking preventive measures. Clinical prediction models are tools that can help oncologists identify at-risk individuals. However, such models are currently not available for clinical oncology practice. This systematic review outlines candidate predictors of low quality of life of colorectal cancer survivors, providing a firm conceptual basis for developing prediction models.

The Impact of Body Mass Index and Waist Circumference on Health-related Quality of Life Among Colorectal Cancer Survivors: Results from the PROFILES Registry

ABSTRACT Background: We aimed to assess the association of waist circumference (WC) and body mass index (BMI) with health-related quality of life (HRQL) among colorectal cancer (CRC) survivors. Methods: CRC survivors diagnosed between 2000 and 2009 completed questionnaires in August 2013 (with self-reported weight, height, and self-assessed WC) and January 2014 (with HRQL using the EORTC-QLQ-C30). Clinical characteristics were retrieved from the Netherlands Cancer Registry. In multivariable linear regression analyses associations of BMI only, WC only and both BMI and WC with HRQL outcomes were assessed. Results: 1,111 CRC survivors were included of whom 34% had a normal weight (18.5 ≤ BMI < 25 kg/m2), 49% had overweight (25 ≤ BMI < 30 kg/m2), 17% had obesity (BMI ≥ 30 kg/m2), and 44% had an increased WC (i.e., >102 and >88 cm for men and women, respectively). Both BMI and WC were separately associated with worse global health status, functioning, and more symptoms of fatigue. Increased WC was associated with lower physical, role and emotional functioning, regardless of BMI, with average differences ranging between 3 and 5 points. Conclusion: Future research on HRQL among CRC survivors should consider both BMI and WC. Furthermore, weight reduction trials should not only focus on general weight loss but also on the loss of abdominal fat.

Explaining the Obesity Paradox-Letter

Nutritional Information Provision to Cancer Patients and Their Relatives Can Promote Dietary Behavior Changes Independent of Nutritional Information Needs

ABSTRACT We investigated whether obtaining nutritional information influences reported changes in dietary behavior in cancer survivors and their relatives and whether nutritional information needs influence this association. We included 239 cancer survivors and their relatives, recruited from an online panel of cancer survivors and relatives. This panel completed a survey about their experiences with nutritional information provision by healthcare professionals and the media in the period after diagnosis, their information needs regarding nutrition and cancer, and whether they changed their dietary behavior since diagnosis. The survey showed that 56% of respondents obtained nutritional information, mostly during treatment. Respondents who obtained nutritional information more often reported to have altered their dietary behavior after diagnosis. This association was not altered by having information needs. The reported changes in dietary behavior were coherent with the recommendations of the World Cancer Research Fund: respondents reported to choose less products that promote weight gain, increased intake of plant foods, and decreased meat and alcohol use. Respondents who obtained nutritional information more often changed their dietary behavior, regardless whether they had nutritional information needs. This might be an indication that healthcare professionals should provide nutritional information not only to those expressing a need for nutritional information.

The association between body mass index and postoperative complications, 30-day mortality and long-term survival in Dutch patients with colorectal cancer

INTRODUCTION This retrospective study aims to examine the association between body mass index (BMI) and serious postoperative complications, 30-day mortality and overall survival in colorectal cancer (CRC) patients. MATERIALS AND METHODS All CRC patients diagnosed between 2008 and 2013 in the south-eastern part of the Netherlands were included. Patients were categorized into four BMI groups: underweight (<18.5), normal weight (18.5 ≥ BMI<25), overweight (25 ≥ BMI<30), and obese (≥30). RESULTS A total of 7371 CRC patients were included (underweight 133 (1.8%); normal weight 2054 (41.4%); overweight 2955 (40.1%); obesity 1229 (16.7%)). Underweight patients were more likely to have postoperative complications (18.8% vs. 11.7%, adjusted OR 1.95, 95% CI 1.08-3.49) and had a worse 30-day mortality (9.8% vs. 3.3%, adjusted OR 4.37, 95% CI 2.03-9.42) compared to normal weight patients. After stratification for stage (stage I-III and stage IV), underweight was associated with a worse overall survival in both groups compared to normal weight (stage I-III: HR 2.06, 95%CI 1.51-2.80; stage IV: HR 1.65, 95% CI 1.11-2.45). Overweight was associated with an improved overall survival compared to normal weight in both stage groups. Only in stage IV patients obesity was associated with a significant better overall survival compared to stage IV normal weight patients. CONCLUSION Underweight CRC patients were more likely to have postoperative complications and a worse 30-day mortality compared to patients in other BMI categories. The underweight population also has a worse long-term survival while overweight CRC patients and obese stage IV CRC patients were associated with an improved survival compared to normal weight patients.

An exploration of needs and preferences for dietary support in colorectal cancer survivors: A mixed-methods study

Purpose To describe the proportion of colorectal cancer (CRC) survivors who perceive a need for dietary support; to examine which socio-demographic, cancer-related, and health-related characteristics are associated with this need; to explore reasons for (not) needing support; and to explore CRC survivors’ specific needs and preferences with regard to lifestyle (i.e., dietary, exercise, and/or weight management) support. Methods This mixed-methods study comprised a cross-sectional survey among 1774 Dutch CRC survivors and three focus groups (n = 16). To examine associations, logistic regression analyses were conducted. Focus groups were audio-taped, transcribed verbatim, and analyzed using a thematic approach. Results Of 1458 respondents (82%), 1198 (67.5%) were included for analyses. 17.5% reported a need for dietary support. Characteristics associated with this need were: being younger, living without a partner, having a stoma, having diabetes, and being overweight or obese. The main reason for needing support was being unable to initiate and maintain lifestyle changes without support. CRC survivors preferred receiving information soon after diagnosis to make an autonomous, informed decision on improving their lifestyle. They preferred to receive individually-tailored lifestyle support in an autonomy-supportive environment, preferably with involvement of their family and fellow-sufferers. Conclusions This study has provided knowledge on appropriate support for CRC survivors in need for dietary support to improve health outcomes by promoting adherence to lifestyle and body weight recommendations. Findings can be used to better identify CRC survivors in need for dietary support, and to tailor lifestyle support to their needs and preferences in order to promote uptake, adherence, and effectiveness.

SUN-P082: Comparison of the “ESPEN Guidelines on Nutrition in Cancer Patients 2016” with the Recommendations of the Dutch Dietitians in Oncology Group

Rationale: In 2016, a completely revised second version of the ‘Handbook Nutrition in Cancer’ (HNC, in Dutch) by the Dutch Dietitians Oncology Group (DDOG) was published. In this project, the DDOG evaluated similarities and potential discrepancies between DDOG recommendations and the ESPEN guidelines for the identification, prevention and treatment of reversible elements of malnutrition during and after cancer treatment. Methods: The recommendations of the DDOG, as published in the HCN, were systematically compared with the ESPEN guidelines on nutrition in cancer patients. guidelines. However, DDOG recommendations are more detailed, comprehensive, and practical. The DDOG and the ESPEN guidelines differ in that the DDOG 1) recommends the comprehensive PG-SGA and PG-SGA Short Form for screening and nutritional assessment; 2) recommends to start artificial nutrition at an earlier stage; 3) does not recommend increasing the ratio of energy from fat/energy from carbohydrates in weight-losing cancer patients with insulin resistance; 4) includes a less conservative recommendation on increasing energy intake for prevention of refeeding syndrome; and 5) supports a longer period of corticosteroid use to increase appetite (4-8 weeks vs ESPEN 1-3 weeks). Additionally Results: Overall, the DDOG recommendations are in line with the ESPEN , the DDOG does not include a specific advice for parenteral nutrition composition during intensive chemotherapy, and includes the advice to avoid fatty fish/fish oil 24 hours before and after specific chemotherapy treatment. Both guidelines recommend nutritional care to be accompanied by exercise training. Conclusion: The DDOG and ESPEN recommendations are generally in line with each other, but the DDOG recommendations are more specific and practical. DDOG and ESPEN are complementary to each other.
