RESUMO
BACKGROUND: Severe weight loss is directly responsible for up to one-fifth of all cancer deaths and has a major impact on quality of life. The simplified nutritional appetite questionnaire (SNAQ) was validated to predict weight loss within 6 mo in community-dwelling adults and nursing home residents. METHODS: We prospectively assessed the SNAQ in 133 palliative cancer outpatients. The SNAQ predictions were validated after 3 and 6 mo with the observed weight change. In addition, the treating oncologists gave their predictions concerning future weight loss according to their clinical judgment. RESULTS: A significant weight loss of 5% of the original body weight within 6 mo occurred in 20 (24%) of the 133 patients. The SNAQ predicted weight loss with a sensitivity of 0.38 and a specificity of 0.66 (P-value 0.81). The treating oncologists predicted weight loss with a sensitivity of 0.67 and a specificity of 0.7 (P-value 0.002). CONCLUSION: The SNAQ does not represent a useful tool to predict impending weight loss in palliative cancer outpatients. The predictions of the treating oncologists were more reliable than those from the SNAQ, but remain poor. Better methods to predict weight loss in this patient group are therefore required.

Numerous studies have shown that medically indicated sip feeding is an effective and cost-saving mean to combat malnutrition. Particularly, acutely ill, elderly, polymorbid internal and surgical patients benefit from sip feeding. In Switzerland, the reimbursement of medically indicated sip feeding at home by the compulsory health insurance is critically important for the good of the patient and cost optimization. This is particularly true in the longer-term considering the demographic trends in Switzerland with an important increase of the elderly population. Therefore, the reimbursement of sip feeding was requested from the Federal Department of Home Affairs - with success. Since July 2012, medically indicated sip feeding at home is covered by the compulsory health insurance provided that a medical diagnosis according to the strict and well-defined guidelines from the Society for Clinical Nutrition Switzerland (SSCN) is given.

Background and aims: Although many cancer patients suffer from malnutrition or cancer cachexia, there is no standard of care so far due to limited intervention trials. Pooled data from two combined trials were analyzed regarding nutritional status and survival time. Materials and methods: Data from two trials with advanced cancer patients were included. In both trials, patients in the intervention group received at least three times nutritional counseling and supervised training sessions. Patients in the control group continued being treated according to usual care. Nutritional status was measured using BMI, body composition and handgrip strength. Survival time was analyzed using the Cox proportional hazard model with the period between the beginning of the trial and death as underlying time scale. Results: 68 men (61.8%) and 42 women (38.2%) were randomized either to the intervention (n = 56) or the control (n = 54) group. The inter-group difference for changes in BMI and body composition was not statistically significant after 3 months. Handgrip strength improved significantly from 34.4 ± 10.2 kg to 36.3 ± 9.9 kg at 3 months in the intervention compared to 33.9 ± 9.2 kg to 34.9 ± 9.1 kg in the control group (p = 0.006). The analysis of survival time showed no inter-group difference for all patients. A detailed analysis for different diagnoses showed that in patients with lung cancer, the covariates "CRP value," "days from first diagnosis to randomization" as well as "gender" were significantly associated with survival time. Patients with higher CRP value had a shorter survival time and female patients had a shorter survival time than male patients in our analysis. In addition, patients with pancreatic cancer randomized to the control group had a 20% shorter survival time than those in the intervention group (p = 0.048). Conclusion: The pooled analysis showed a significant improvement of handgrip strength in advanced cancer patients through the implementation of a combined therapy. Handgrip strength is of prognostic significance in hospitalized patients due to its association with mortality and morbidity. However, no improvements in further tests were detected. There is great need for further investigations examining the effect of nutritional and exercise therapy on survival time with focus on different cancer diagnoses.

BACKGROUND & AIMS: Cancer cachexia is multifactorial and should be targeted using a multimodal form of intervention. The purpose of the present trial was to test the effects of a combined nutrition and physical exercise program on cancer patients with metastatic or locally advanced tumors of the gastrointestinal and lung tracts. METHODS: Patients were randomized into two groups: One group received a minimum of three standardized individual nutritional counselling sessions and participated in a 60-min exercise program twice a week. The second group received their usual care. The intervention spanned a period of three months. Quality of life (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire version 3.0), physical performance (hand-grip strength, 6-min walk test, timed sit-to-stand test and 1 repetition maximum leg press), nutritional status (body weight, bioelectrical impedance analysis), dietary intake (three-day dietary record) and clinical data (unexpected hospital days, performance status) were tested at baseline and after three and six months. RESULTS: In total, 18 women and 40 men (mean age 63, range 32-81) with metastatic or locally advanced tumors of the gastrointestinal (n = 38) and lung (n = 20) tracts were included. Median adherence to the supervised exercise program was 75%. The median number of individual nutritional counselling sessions was 3.0 (range 0-7 sessions). Post intervention, no difference in global health status/quality of life (overall QoL) was observed. Intervention was superior to UC for the patient-rated symptom scale regarding nausea and vomiting (p = 0.023) and protein intake (p = 0.01). No statistical differences were observed for energy intake, nutritional status and physical performance. CONCLUSIONS: The results show good adherence to a combined nutrition and exercise program. The multimodal intervention did not improve overall QoL, but contributed to an adequate protein intake and to the general well-being of the patient by reducing nausea and vomiting.

OBJECTIVE: Weight loss is common in patients with malignant tumors and it can adversely affect quality of life and survival. The aim of the present study was to investigate the effects of a nutritional intervention in cancer patients in an outpatient setting. METHODS: Cancer outpatients (N = 58) who were classified as undernourished or at high risk for undernutrition by the Nutritional Risk Screening 2002 tool were randomized into two groups. One group (n = 30) received standardized individual nutritional therapy, including counseling by a dietitian, food fortification, and oral nutritional supplements if required. The second group (n = 28) received standard care. The nutritional intervention lasted 3 mo. Dietary intake (3-d dietary record), nutritional status (body weight), physical functioning (performance status, hand-grip strength) and quality of life (European Organization for Research and Treatment of Cancer Quality of Life Questionnaire version 3.0) were assessed at baseline and after 6 wk and 3 mo. An additional follow-up assessment was carried out 3 mo post-intervention. RESULTS: Nutritional intervention led to a significantly higher average energy and protein intake in the nutritional therapy group (+379 kcal; 95% confidence interval [CI], 117-642; P = 0.007, respectively; +10.4 g; 95% CI, 2.3-18.5; P = 0.016). However, the increased dietary intake was not associated with improvements in nutritional status, physical functioning, or quality of life. CONCLUSIONS: Individual nutritional counseling significantly and positively influenced energy and protein intake, but did not improve nutritional or physical outcome or quality of life. These results indicate that nutritional therapy alone is of limited efficacy in cancer patients whose nutritional status has already deteriorated.
