RESUMEN
OBJECTIVE: Gastrointestinal (GI) cancer patients often experience severe malnutrition during cancer therapies due to gastrointestinal dysfunctions including poor digestion and absorption as well as tumor-associated anorexia. In this study, we performed a randomized clinical trial to determine the efficacy of oral nutrition supplement (ONS) enriched with omega-3 fatty acids on nutritional status, quality of life (QOL), and pro-inflammatory indices. METHODS: Patients diagnosed with GI cancers were recruited and screened for eligibility. A total of 58 patients were randomly allocated to either the control group (n=27) or the experimental group (n=31). The intervention group received 200 ml ONS twice a day while the control group received routine care. Anthropometrics, Patient-Generated Subjective Global Assessment (PG-SGA) score, QOL score and nutrient intake data were collected at baseline, week 4 and week 8. Blood was drawn for biochemical assessments. Nine patients from each group dropped out of the study Forty patients (18 control patients and 22 intervention patients) completed the study. RESULTS: This study showed that ONS intervention improved PG-SGA scores in the intervention group (p<0.01). Scores of physical functioning score and role functioning were declined only in the control group and the difference between week 8 and baseline for role functioning was significant (p<0.001). Fatigue score was steadily decreased in the experiment group, and the differences between week 8 and baseline was significant between two groups (p<0.02). However, no statistically significant improvement in biochemical markers of nutritional status and pro-inflammatory cytokine concentrations were found. These results suggests that ONS intervention for 8 weeks improves PG-SGA scores and QOL scores in patients undergoing cancer therapy.

The standard treatment for gastrointestinal cancer is surgical resection and perioperative adjuvant treatment. Multidisciplinary treatment for gastrointestinal cancer leads to body composition changes. Body composition changes, such as skeletal muscle loss and body weight loss, during multidisciplinary treatment result in poor physical activity, severe toxicity of chemotherapy and/or radiation therapy, and poor oncological outcomes. Therefore, the hypothesis is that minimization of body composition changes during multidisciplinary treatment in gastrointestinal cancer patients, the continuation of postoperative adjuvant treatment in these patients might improve, thereby improving the oncological outcomes. Given this hypothesis, recent studies have focused on introducing perioperative oral nutritional treatment for gastrointestinal cancer patients. Thus far, oral nutritional treatment has proven promising and showed some clinical benefits for gastrointestinal cancer patients during the perioperative period. However, whether or not oral nutritional treatment has clinical benefits on the long-term oncological outcomes in gastrointestinal cancer remains unclear. To optimize oral nutritional treatment for gastrointestinal cancer patients, it is necessary to clarify the benefits of oral nutritional treatment on the long-term oncological outcomes in gastric cancer patients and establish the optimal approach to oral nutritional treatment.

Nutrition and gastrointestinal cancer are inextricably linked. The metabolic effects of cancer along with changes in dietary intake, the development of cancer cachexia and the presence of sarcopenia can influence changes in body composition. These have a negative impact on quality of life and tolerance to cancer treatment. Treatment for cancer presents some significant nutritional challenges as nutrition impact symptoms may develop, be exacerbated by treatment and may contribute to a worsening in nutritional status. Nutrition screening and assessment should be an integral part of holistic patient care. The provision of appropriate, evidence-based dietary advice should occur before, during and after cancer treatment. Appropriate and timely methods of nutritional support across the spectrum of gastrointestinal cancer are needed to ensure that people are adequately supported during courses of treatment that can span weeks and months. These can range from standard approaches of supplementing oral intake to complex interventions such as managing high output intestinal stomas. The gastrointestinal tract is particularly susceptible to impact from systemic anti-cancer treatments and radiotherapy. Gastrointestinal late effects of cancer treatment are now recognised to present particular challenges in terms of both medical and nutritional management. These late effects have a significant impact on the individual and their quality of life in addition to implications for the health service. Dietary intake following cancer treatment has an impact on quality of life and future research may demonstrate its influence on the risk of recurrence of gastrointestinal cancer.

OBJECTIVE: Gait is a sensitive marker for functional declines commonly seen in patients treated for advanced cancer. We tested the effect of a combined exercise and nutrition programme on gait parameters of advanced-stage cancer patients using a novel wearable gait analysis system. METHODS: Eighty patients were allocated to a control group with nutritional support or to an intervention group additionally receiving whole-body electromyostimulation (WB-EMS) training (2×/week). At baseline and after 12 weeks, physical function was assessed by a biosensor-based gait analysis during a six-minute walk test, a 30-s sit-to-stand test, a hand grip strength test, the Karnofsky Index and EORTC QLQ-C30 questionnaire. Body composition was measured by bioelectrical impedance analysis and inflammation by blood analysis. RESULTS: Final analysis included 41 patients (56.1% male; 60.0 ± 13.0 years). After 12 weeks, the WB-EMS group showed higher stride length, gait velocity (p < .05), six-minute walking distance (p < .01), bodyweight and skeletal muscle mass, and emotional functioning (p < .05) compared with controls. Correlations between changes in gait and in body composition, physical function and inflammation were detected. CONCLUSION: Whole-body electromyostimulation combined with nutrition may help to improve gait and functional status of cancer patients. Sensor-based mobile gait analysis objectively reflects patients' physical status and could support treatment decisions.

The improvement of sleep quality in patients with cancer has a positive therapeutic effect on them. However, there are no specific treatment guidelines for treating sleep disturbance in cancer patients. We investigated the effect of forest therapy on the quality of sleep in patients with cancer. This study was conducted on nine patients (one male, eight female; mean age, 53.6 ± 5.8 years) with gastrointestinal tract cancer. All patients participated in forest therapy for six days. They underwent polysomnography (PSG) and answered questionnaires on sleep apnea (STOP BANG), subjective sleep quality (Pittsburgh Sleep Quality Index, PSQI), sleepiness (Stanford and Epworth Sleepiness Scales), and anxiety and depression (Hospital Anxiety and Depression Scale) to evaluate the quality of sleep before and after forest therapy. Sleep efficiency from the PSG results was shown to have increased from 79.6 ± 6.8% before forest therapy to 88.8 ± 4.9% after forest therapy (p = 0.027) in those patients, and total sleep time was also increased, from 367.2 ± 33.4 min to 398 ± 33.8 min (p = 0.020). There was no significant difference in the STOP BANG score, PSQI scores, daytime sleepiness based on the results of the Stanford and Epworth Sleepiness Scales, and depression and anxiety scores. Based on the results of this study, we suggest that forest therapy may be helpful in improving sleep quality in patients with gastrointestinal cancers.

BACKGROUND: Many patients with cancer or other systemic illnesses can experience malnutrition. One way to mitigate malnutrition is by insertion of a percutaneous endoscopic gastrostomy feeding tube (PEG tube). The goal of this retrospective matched cohort study is to evaluate if PEG tube placement improved nutritional status and overall survival (OS) in advanced gastroesophageal (GE) cancer patients who are undergoing anti-neoplastic therapy. METHODS: GE cancer patients who were treated and evaluated by a nutritionist and had at least 2 nutritionist follow-up visits were identified. Patients with PEG tube were matched to patients that did not undergo PEG placement (non-PEG). Clinical characteristics, GE symptoms reported at nutrition follow-up visits, and OS were recorded. RESULTS: 20 PEG and 18 non-PEG cases met criteria for further analyses. After correction for multiple testing, there were no OS differences between PEG and non-PEG, treatment naive and previously treated. However, PEG esophageal carcinoma has statistically significant inferior OS compared with non-PEG esophageal carcinoma. PEG placement did not significantly reduce the proportion of patients with weight loss between the initial nutrition assessment and 12-week follow-up. CONCLUSIONS: In this small study, PEG placement had inferior OS outcome for GE esophageal carcinoma, no improvement in OS for other evaluated groups, and did not reduce weight loss between baseline and 12-week follow-up. Unless there is prospective randomized trial that can show superiority of PEG placement in this population, PEG placement in this group cannot be endorsed.

BACKGROUND: Adequate circadian timing of cancer treatment schedules (chronotherapy) can enhance tolerance and efficacy several-fold in experimental and clinical situations. However, the optimal timing varies according to sex, genetic background and lifestyle. Here, we compute the individual phase of the Circadian Timing System to decipher the internal timing of each patient and find the optimal treatment timing. METHODS: Twenty-four patients (11 male; 13 female), aged 36 to 77 years, with advanced or metastatic gastro-intestinal cancer were recruited. Inner wrist surface Temperature, arm Activity and Position (TAP) were recorded every 10 min for 12 days, divided into three 4-day spans before, during and after a course of a set chronotherapy schedule. Pertinent indexes, I < O and a new biomarker, DI (degree of temporal internal order maintenance), were computed for each patient and period. RESULTS: Three circadian rhythms and the TAP rhythm grew less stable and more fragmented in response to treatment. Furthermore, large inter- and intra-individual changes were found for T, A, P and TAP patterns, with phase differences of up to 12 hours among patients. A moderate perturbation of temporal internal order was observed, but the administration of fixed chronomodulated chemotherapy partially resynchronized temperature and activity rhythms by the end of the study. CONCLUSIONS: The integrated variable TAP, together with the asynchrony among rhythms revealed by the new biomarker DI, would help in the personalization of cancer chronotherapy, taking into account individual circadian phase markers.

Malaria is responsible for more deaths around the world than any other parasitic disease. Due to the emergence of strains that are resistant to the current chemotherapeutic antimalarial arsenal, the search for new antimalarial drugs remains urgent though hampered by a lack of knowledge regarding the molecular mechanisms of artemisinin resistance. Semisynthetic compounds derived from diterpenes from the medicinal plant Wedelia paludosa were tested in silico against the Plasmodium falciparum Ca2+-ATPase, PfATP6. This protein was constructed by comparative modelling using the three-dimensional structure of a homologous protein, 1IWO, as a scaffold. Compound 21 showed the best docking scores, indicating a better interaction with PfATP6 than that of thapsigargin, the natural inhibitor. Inhibition of PfATP6 by diterpene compounds could promote a change in calcium homeostasis, leading to parasite death. These data suggest PfATP6 as a potential target for the antimalarial ent-kaurane diterpenes.

BACKGROUND & AIMS: Weight loss and malnutrition are frequent problems in oncology patients. The aim of this study was to get a perspective of the current practice of parenteral nutrition (PN) care in an outpatient setting and to improve patient-centered nutritional care. METHODS: Fifty-three outpatient oncology centers participated in this observational study performed between July 2010 and March 2011. All participating centers entered data online into a web-based documentation form, containing a number of oncology patients, diagnoses, and detailed data about oncology patients receiving PN. RESULTS: Two cohorts were analyzed. First cohort consisted of all oncology patients in quarter 04/2010. Second cohort consisted of patients with PN during the whole studying period. In the first cohort 2.46% (n = 626) of 25,424 oncology patients received PN. Most frequent diagnoses of patients receiving PN were gastric cancer (n = 119) and colorectal cancer (n = 104), however most stated diagnosis was "other" (n = 163). In the second cohort (n = 1137), a common indication for PN was impaired gastrointestinal passage (n = 177), although here again most stated reason was "other" (n = 924). In the course of the PN treatment, patients (n = 1137) showed a stable or slowly increasing body mass index (from 21.6 ± 3.8 kg/m(2) to 21.8 ± 3.5 kg/m(2)). CONCLUSION: This is the largest study outlining the characteristics of oncology patients in the context of PN in German ambulatory centers. They confirm the important role of PN in the care of gastrointestinal cancer. Further studies have to be performed to identify if other indications than those mentioned in relevant guidelines can trigger initiation of PN.

Immune nutrition refers to adding some special nutrients to the standard formula of nutrition in order to treat and regulate metabolism and immune function by its pharmacological effect. In recent years, immune nutrition, including glutamine, arginine, ω-3 PUFA, nucleotide etc, has been widely used in patients with gastrointestinal cancer. These nutrients show their different supporting functions through different mechanisms, and improve the clinical outcome of patients. Therefore, clinical nutrition has been expanded and upgraded from the traditional "nutrition" to "nutritional therapy".

PURPOSE OF REVIEW: Chronic infection of the gastric mucosa with Helicobacter pylori has long been recognized as a significant risk factor for gastric cancer, and indeed, this model represents the prototypical inflammation-associated cancer. In this review, we present the latest clinical and experimental evidence showing that gastrin peptides and their receptors [the cholecystokinin (CCK2) receptors] potentiate the progression of gastric cancer and other gastrointestinal malignancies in the presence of inflammation. RECENT FINDINGS: We highlight the feed-forward mechanisms by which gastrin and CCK2 receptor expression are upregulated during inflammation and in gastrointestinal cancers, summarize gastrin's proinflammatory role by inducing the production of cyclooxgenase-2 (COX-2) and interleukin-8 (IL-8), and relate evidence suggesting that gastrin and their receptors modulate the function of immune cells and fibroblasts following cellular stress, injury, repair, as well as during cancer progression. SUMMARY: We discuss trends for future studies directed toward the elucidation of gastrin peptides' role in regulating intercellular molecular signaling mechanisms between local and circulating immune cells, fibroblasts, epithelial cells, and other cell types in the microenvironments of inflammation-related cancers. Elucidation of the molecular and cellular pathways that relate inflammation with cancer may provide additional opportunities to develop complementary therapies that target the inflammatory microenvironment of the cancer.

Yin-Deficiency (YD), representing a status of the human body under lack of nutrition and fluid in traditional Chinese medicine, is commonly seen in late stage of cancer patients. It is not known whether the severity of YD related symptoms/signs can predict the survival rate of cancer patients. This study evaluated the distribution of Yin-deficiency symptoms/signs (YDS) in cancer patients with YD, and investigated whether the severity of YDS can predict the survival rate of cancer patients with YD. From 5 January 2007 to 5 May 2007, we selected 43 cancer patients with diagnosis of YD from hospitalized patients and outpatients. The severity of YD was evaluated by a questionnaire. We further estimated the cumulative probabilities of the survival rates over 4 months since the start of study by the Kaplan-Meier product-limit method, and compared the differences among groups with various severities in each symptom/sign with the use of the log-rank test. The results revealed that, the 3 most common YDS were sleeplessness with annoyance, less or non-coated tongue with or without redness and dry mouth. In the survival rate analysis, only 2 parameters, rapidly small pulse (p = 0.002) and less-or non-coated tongue with paleness (p = 0.017), were found to be related to the decrease of cancer patients with YD. This suggests that, both rapidly small pulse and less-or non-coated tongue without redness may be used as predictors for the estimation of survival rate in cancer patients with YD.

INTRODUCTION: In patients with gastrointestinal (GI) cancer, severe malnutrition is associated with increased morbidity and mortality, reduction of treatment efficacy, and increased length of hospital stay. Therefore, systematic screening and care of malnutrition is mandatory. MATERIALS AND METHODS: Data for this review were identified by searches of Medline with and without MeSH database and Cancerlit. Studies were selected only if they were randomised clinical trials or historical reports. References were also identified from reference lists in relevant previously published articles. Recent guidelines and meta-analyses were included. Only articles published in English were taken into consideration. RESULTS: For surgical patients, practical information such as weight loss or subjective global assessment would provide a better basis for deciding whether or not to delay surgery. At least 10 days of nutritional support is recommended in severely malnourished patients before major digestive surgery. In non-severely malnourished patients, preoperative oral immunonutrition is associated with a 50% decrease in postoperative complications. The benefit of immune-enhancing diets in severely malnourished patients remains to be proven. For patients undergoing radiochemotherapy, dietary counselling should be proposed to all patients. In cases of severely malnourished patients or if dietary counselling suffers a setback, enteral nutrition should be recommended. Parenteral nutrition should be reserved for patients with severe digestive intolerance when enteral nutrition is not possible. CONCLUSION: Propose an adaptive nutritional support at each step of a multimodal GI oncological treatment is essential. These recommendations should be used in daily practice but should also be included in all clinical research protocols.

Even after receiving analgesia, patients with gastric and liver cancer still report moderate levels of postoperative pain. The purpose of the study was to investigate the efficacy of foot reflexotherapy as adjuvant therapy in relieving pain and anxiety in postoperative patients with gastric cancer and hepatocellular cancer. The study design was a randomized controlled trial. Data were collected from 4 surgical wards of a medical center in 2005 in Taipei, Taiwan. Sixty-one patients who had received surgery for gastric cancer or hepatocellular carcinoma were randomly allocated to an intervention (n = 30) or control (n = 31) group. Patients in the intervention group received the usual pain management plus 20 minutes of foot reflexotherapy during postoperative days 2, 3, and 4. Patients in the control group received usual pain management. Outcome measures included the short-form McGill Pain Questionnaire, visual analog scale for pain, summary of the pain medications consumed, and the Hospital Anxiety and Depression Scale. Results demonstrated that studied patients reported moderately high levels of pain and anxiety postoperatively while patients were managed with patient-controlled analgesia. Using generalized estimation equations and controlling for confounding variables, less pain (P < .05) and anxiety (P < .05) over time were reported by the intervention group compared with the control group. In addition, patients in the intervention group received significantly less opioid analgesics than the control group (P < .05). Findings from this study provide nurses with an additional treatment to offer postoperative digestive cancer patients.

OBJECTIVE: To observe the influence of chemotherapy with FOLFOX protocol (CT-F) on sex hormones of male patients, and the protective and detoxifying effect of herbal medicines for reinforcing Shen and supplementing qi (HM) on it. METHODS: The randomized block control and self-control design was adopted to retrospectively investigate the changes of sex hormones in 61 patients with cancer of colon, rectum or stomach. They were assigned to four groups, A: treated simply with HM; B: treated with CT-F; C: treated with CT-F combined with HM; D: the blank control group. One course of CT-F composed of 1 month treatment, and 6 courses totally were applied on each patients. The levels of luteinizing hormone (LH), estradiol (E2), prolactin (PRL), progesterone (P), testosterone (T) and follicle-stimulating hormone (FSH) were determined before treatment (T0), at the end of the 6th month treatment (T1) and the 12th month (T2) after starting treatment. RESULTS: Levels of LH, PRL and T were significantly lowered in the group B at T1, being 4.6 +/- 0.4 IU/L, 8.6 +/- 0.7 microg/L and 13.1 +/- 1.4 IU/L, respectively, which were significantly different to those in the other 3 groups at the corresponding time; they were somewhat raised after chemotherapy but still lower at T2 than those at T0, being 5.0 +/- 0.4 IU/L, 9.9 +/- 1.1 microg/L and 14.1 +/- 1.4 IU/L respectively, also lower than the corresponding levels in the other 3 Groups (P<0.05 or P<0.01). In group C, LH significantly lowered at T1 (P<0.05) to 5.1 +/- 0.4 IU/L, but it was restored to the levels of T0 and that in Group D, reaching 6.1 +/- 0.5 IU/L; while PRL and T were changed insignificantly in the chemotherapeutic course, and restored at T2 to the level of T0, comparable to that in group D. Contrarily, levels of E2 and FSH increased significantly (P <0.01) in group B after chemotherapy (at T1) to 135 +/- 14 pmol/L and 9.1 +/- 1.1 IU/L respectively, and till T2, being 140 +/- 15 pmol/L and 9.1 +/- 1.o IU/L, they were lower than those at T0 and higher than those in group D, A and C ( all P <0.01), but the two indexes were not significantly increased in group C, being 116 +/- 12 pmol/L and 7.1 +/- 0.9 IU/L at T1. However, all the parameters showed no significant change in group A and D, and the level of P showed insignificant change in all the groups in the whole observation period. CONCLUSION: CT-F could induce multiple sex hormonal abnormalities in male patients with post-operational gastrointestinal cancer, and HM shows protective and detoxifying effects on them in different degrees.

AIM: To assess the effects of poor nutritional and psychological status on tolerance of cancer treatment and the recovery of physical performance status in patients with gastrointestinal cancer. METHODS: An epidemiological survey with respect to nutritional and psychological status in patients with gastrointestinal cancer was conducted among 182 operated patients in four provincial-level hospitals from December 2005 to June 2006. The food frequency survey method, state-trait anxiety inventory (STAI) and depression status inventory (DSI) were used to obtain information about the diet and psychological status in the patients. Nutritional status in the participants was reflected by serum albumin (Alb), hemoglobin (HB) and body mass index (BMI). RESULTS: Alb, protein intake and anxiety were associated with the severity of side effects of treatment. The adjusted relative risk (RR) for Alb, protein intake and anxiety was 3.30 (95% CI: 1.08, 10.10, P = 0.03), 3.25 (95% CI: 1.06, 9.90, P = 0.04) and 1.48 (95% CI: 1.29, 1.70, P < 0.0001), respectively. Moreover, calorie intake, HB and depression were associated with the recovery of physical performance status in the patients. Adjusted relative risk was 2.12 (95% CI: 1.09, 4.03, P = 0.028), 2.05 (95% CI: 1.08, 3.88, P = 0.026) and 1.07 (95% CI: 1.02, 1.12, P = 0.007), respectively. CONCLUSION: Both poor nutrition status and psychological status are independent risk factors for severe side effects of cancer treatment, and have impact on the recovery of physical performance status in patients after treatment.

Gastrointestinal stromal tumors (GIST) are defined as c-KIT-positive mesenchymal neoplasias located in the gastrointestinal tract and abdomen, most of which present an activating KIT mutation, a fundamental step in the development of disease. However, recent studies reported a small subgroup of KIT-negative GIST, in which platelet-derived growth factor receptor A, protein kinase C-tau, and FLJ10261 expression was detected. Imatinib (Gleevec, Novartis) is an orally administered competitive inhibitor of the tyrosine kinase domain of receptors such as KIT, ABL, and BCR-ABL fusion proteins, and the platelet-derived growth factor receptor. Phase I-III clinical trials have demonstrated the efficacy of imatinib in the treatment of metastatic GIST. However, the optimal dose and role of imatinib in an adjuvant or neoadjuvant setting have yet to be defined. Therefore, further studies investigating the mechanism of resistance to imatinib in patients with GIST are warranted.

This article discusses how staff development educators can conduct an innovative class for nurses caring for patients with gastrointestinal cancer. The nurse's role in caring for these patients includes knowledge of the pathophysiology, risk factors, detection methods, signs and symptoms, treatments, conventional and integrative holistic nursing interventions, and community resources. However, consideration should be given to the total learning experience rather than technical skills alone.

This study analyzed the nutritional status of cancer patients in relation to type and site of origin of the tumor, stage of disease, and previous chemical or radiation therapy. The analysis was performed on 321 patients (280 with cancer and 41 controls). The nutritional parameters included per cent of weight loss, anthropometric indices (arm circumference, triceps skinfold, arm muscle circumference), creatinine-height index, serum protein, albumin, total iron binding capacity and cholinesterase, C3 and C4 components of complement, total peripheral lymphocytes, and skin tests. The statistical comparison between patients with different tumors and controls, between patients with different stages of the same tumor, and between patients treated with or without previous chemical or radiation therapy led to the following conclusions: 1) malnutrition is mainly related to the type and site of origin of the tumor and, in the early stages of disease, is more pronounced in patients with cancer of the esophagus and stomach; 2) except in patients with breast and cervix cancer, malnutrition gets more severe as the disease becomes advanced; 3) chemical or radiation therapy has a variable impact on the nutritional status, but in selected patients it causes a drop in body weight, arm circumference, arm muscle circumference, and peripheral lymphocytes; 4) body weight, cutaneous delayed hypersensitivity and serum albumin are the most commonly altered parameters.
