Health-related quality of life and occurrence of intestinal side effects after pelvic radiotherapy - Evaluation of long-term effects of diagnosis and treatment

Health-related quality of life (HRQOL) and occurrence of late intestinal side effects were assessed 3-4 years after pelvic radiotherapy for carcinoma of the endometrium and cervix. During 1988-1990, 143 women were included in a clinical trial to evaluate the effect of a low fat, low lactose diet on radiation-induced diarrhoea. Of 94 survivors, 79 (84%) answered the request. HRQOL was assessed by the EORTC QLQ-C36 and compared with population-based norms. The women scored lower than the general population on role functioning (81.5 versus 90.6 (p<0.01)) and higher on diarrhoea (23.8 versus 9.5 (p<0.01)). Compared with pre-treatment conditions, an increase in cases with pain in the lower back, hips and thighs was seen. Substantial pain and diarrhoea were associated with deterioration in HRQOL. In conclusion, few treatment and/or disease-related effects were detected 3-4 years after radiotherapy, with the exception of increased bowel frequency and pain in the lower back, hips and thighs.Health-related quality of life (HRQOL) and occurrence of late intestinal side effects were assessed 3-4 years after pelvic radiotherapy for carcinoma of the endometrium and cervix.

No induction of anti-avenin IgA by oats in adult, diet-treated coeliac disease

Objective. Coeliac disease is effectively treated with a gluten-free diet devoid of wheat, rye, barley and related cereals. Oats has until recently also been considered harmful but is now allowed in several countries. We have, however, identified three adult coeliac disease patients who developed a flare of active coeliac disease after ingestion of oats, which suggests that oats might not be entirely innocent in coeliac disease. It is known that patients with untreated coeliac disease have elevated IgA antibodies to oat prolamins. The objective of this study was to investigate whether levels of IgA against oats were increased in treated, adult coeliac disease patients. Material and methods. Serum was collected from 136 adult patients with treated coeliac disease and 139 controls. Eighty-two of the coeliac disease patients had been taking oats as part of their gluten-free diet for 6 months or more. IgA against oats avenin, wheat gliadin and tissue transglutaminase was tested with ELISA. Results. No significant differences were found in IgA against oats in oats-eating and non-oats-eating coeliac disease patients. Both groups had increased levels of IgA against wheat, oats and tissue transglutaminase compared to healthy controls. A significant positive correlation was found between anti-avenin and antigliadin IgA (p<0.0001), and between anti-avenin and anti-tissue transglutaminase IgA (p=0.0012). Conclusions. Ingestion of oats does not cause increased levels of IgA against oats in adult coeliac disease patients on a gluten-free diet. The findings support the notion that most adult coeliac disease patients can tolerate oats.

Dietary treatment of weight loss in patients with advanced cancer and cachexia: A systematic literature review

PURPOSE A systematical literature review evaluating the effect of dietary counseling in treating weight loss and improving energy intake in patients with advanced cancer with different stages of cachexia. PRINCIPAL RESULTS Five publications were retrieved, of which three were randomized. Two out of five studies showed less weight loss with dietary counseling (+1% weight gain vs. -1.5% weight loss, p=0.03, 1.4kg vs. -2kg, p<0.05), two presented positive effect on energy intake (92% of total caloric need vs. 73%, p<0.01, 1865±317kcal vs. 1556±497kcal, ns). CONCLUSION Dietary counseling can effect energy intake and body weight, however, apparent heterogeneity between studies is present. Based on these results there is not enough proof of evidence that dietary counseling given to patients with cancer is beneficial for improving weight or energy balance in the different cachexia stages. Nutrition is an essential part of cachexia treatment as it is not considered possible to increase or stabilize weight if nutritional needs are not met.

The influence of low fat, low lactose diet on diarrhoea during pelvic radiotherapy

In a prospective clinical trial 143 women undergoing pelvic radiotherapy for gynaecological malignancies, were randomized to receive either a low-fat, low-lactose diet (intervention group) or a regular diet (control group) in order to evaluate the possible impact of diet therapy on radiation induced diarrhoea, nausea and vomiting. The daily number and consistency of stools, use of antidiarrhoeal agents, nausea and vomiting were recorded before radiotherapy was begun (week 0), in the last week of therapy (week 6) and 6 weeks after the end of therapy (week 12). The intervention group used half the amount of antidiarrhoeal agents in week 6, than used by the control group (mean 0.6 tablets per day versus 1.1, p < 0.01). 14 patients (23%) in the intervention group reported diarrhoea, versus 32 (48%) in the control group (p < 0.01). In week 12 there were no differences in the use of antidiarrhoeal agents and the prevalence of diarrhoea between the groups.

A randomized phase II feasibility trial of a multimodal intervention for the management of cachexia in lung and pancreatic cancer

Cancer cachexia is a syndrome of weight loss (including muscle and fat), anorexia, and decreased physical function. It has been suggested that the optimal treatment for cachexia should be a multimodal intervention. The primary aim of this study was to examine the feasibility and safety of a multimodal intervention (n‐3 polyunsaturated fatty acid nutritional supplements, exercise, and anti‐inflammatory medication: celecoxib) for cancer cachexia in patients with incurable lung or pancreatic cancer, undergoing chemotherapy.

Comparing Two Classifications of Cancer Cachexia and Their Association with Survival in Patients with Unresected Pancreatic Cancer

There is no universally accepted definition of cancer cachexia. Two classifications have been proposed; the 3-factor classification requiring ≥2 of 3 factors; weight loss ≥10%, food intake ≤1500 kcal/day, and C-reactive protein ≥10 mg/l, and the consensus classification requiring weight loss >5% the past 6 mo, or body mass index <20 kg/m2 or sarcopenia, both with ongoing weight loss >2%. Precachexia is the initial stage of the cachexia trajectory, identified by weight loss ≤5%, anorexia and metabolic change. We examined the consistency between the 2 classifications, and their association with survival in a palliative cohort of 45 (25 men, median age of 72 yr, range 35–89) unresected pancreatic cancer patients. Computed tomography images were used to determine sarcopenia. Height/weight/C-reactive protein and survival were extracted from medical records. Food intake was self-reported. The agreement for cachexia and noncachexia was 78% across classifications. Survival was poorer in cachexia compared to noncachexia (3-factor classification, P = 0.0052; consensus classification, P = 0.056; when precachexia was included in the consensus classification, P = 0.027). Both classifications showed a trend toward lower median survival (P < 0.05) with the presence of cachexia. In conclusion, the two classifications showed good overall agreement in defining cachectic pancreatic cancer patients, and cachexia was associated with poorer survival according to both.

Duration of lactation, maternal metabolic profile, and body composition in the Norwegian EBBA I-study.

OBJECTIVE There is conflicting evidence as to whether duration of lactation may decrease the risk of subsequent development of an unfavorable maternal metabolic profile, including overweight and obesity. We hypothesized that duration of lactation is associated with a more favorable metabolic profile and healthier anthropometric measurements. SUBJECTS AND METHODS Ninety-eight parous women were studied from the Norwegian EBBAI-study (Energy Balance and Breast cancer Aspects-study), a cross-sectional study of healthy premenopausal women 25-35 years old. Historical lactation data were collected, anthropometric measurements were taken, fasting blood samples (for serum glucose, triglycerides, total cholesterol, and high-density lipoprotein cholesterol) were drawn, and women were asked to fill in a precoded food diary. RESULTS Mean time since last birth was 4.7 years, mean number of children was 1.9, mean total duration of lactation was 19 months, and average length of lactation per child was 10.3 months. Women who on average lactated for less than 10 months per child had higher mean levels of fasting serum glucose (5.2 mmol/L vs. 5.0 mmol/L, p=0.04), serum triglyceride (0.91 mmol/L vs. 0.66 mmol/L, p=0.001), and serum cholesterol (4.78 mmol/L vs. 4.32 mmol/L, p=0.004) and a higher waist-to-hip ratio (0.81 vs. 0.77, p=0.001) than women who lactated for 10 months or more per child. The inverse association between average length of lactation per child and waist-to-hip ratio persisted after adjustment for potential confounders. CONCLUSIONS These results support the hypothesis that duration of lactation may be associated with a healthier metabolic profile and healthier anthropometric measurements, especially lipid levels and waist-to-hip ratio, even years after weaning.

Muscle mass and association to quality of life in non-small cell lung cancer patients

Cancer wasting is characterized by muscle loss and may contribute to fatigue and poor quality of life (QoL). Our aim was to investigate associations between skeletal muscle index (SMI) and skeletal muscle radiodensity (SMD) and selected QoL outcomes in advanced non‐small cell lung cancer (NSCLC) at diagnosis.

The impact of nutritional status, physical function, comorbidity and early versus late start in dialysis on quality of life in older dialysis patients

Abstract Background: For the majority of the older patients in dialysis, the treatment will be lifelong. Thus, quality of life (QoL) is a crucial outcome. Our aim was to assess the QoL of older Norwegian dialysis patients and to investigate the impact of early (estimated glomerular filtration rate, eGFR ≥10 mL/min) versus late (eGFR <10 mL/min) start in dialysis, comorbidity, nutritional status and physical capacity. Methods: A self-report questionnaire including SF-36 (QoL) and the Subjective Global Assessment (SGA; nutritional status) was mailed to all patients (n = 320) ≥75 years registered in the Norwegian Renal Registry (NRR) as being in dialysis by September 2009. Reply was received from 233 patients (73%). Medical data including comorbidities and eGFR at dialysis start (obtained for 194 patients) were retrieved from the NRR. Functional capacity was determined from the SGA. Results: Compared to reports from younger dialysis patients, our patients scored poorer on all SF-36 subscales. Early start in dialysis was registered for 52 patients, 142 patients started late, 51.4% were well nourished (SGA A), 32.3% moderately malnourished (SGA B) and 16.4% were severely malnourished (SGA C). No significant association between any SF-36 scores and early versus late start, nutritional status or comorbidity was found. Better physical function was significantly associated with better scores on all SF-36 scales. Conclusions: Our results indicate that physical function is important to all QoL aspects. Increased focus on physical rehabilitation seems pertinent. Early start of dialysis treatment was not associated with better long term QoL scores.

Associations of social networks with quality of life, health and physical functioning

Abstract The aim of this study was to assess whether demographic and social network variables, independently of each other, are associated with quality of life (QoL), self-rated health or physical function. The sample consisted of 307 women aged ≥ 75 years. Social networks were assessed by Fillenbaum’s five questions and a question on ability to participate in organizations. Variables of demographic composition, QoL, health and physical function were registered. We found significant associations between social networks, QoL, health and physical functioning. Seeing friends and relatives as often as wanted, getting help when sick or disabled and having no problems participating in organizations were associated with higher QoL. Higher educational level, the ability to see friends and relatives as often as wanted and having no problems participating in organizations were associated with better health. Living alone, getting help when sick or disabled and having no problems participating in organizations indicated better mobility. Being younger, having higher education and no problems in participating in organizations were associated with better balance. Higher scores on muscle strength were associated with being younger, not living alone and having no problems in participating in organizations. Our results highlight the importance of social networks for maintaining good QoL, health and physical functioning.
