PURPOSE: The present study was designed to evaluate whether daily insulin treatment for weight-losing cancer patients attenuates the progression of cancer cachexia and improves metabolism and physical functioning in palliative care. EXPERIMENTAL DESIGN: One hundred and thirty-eight unselected patients with mainly advanced gastrointestinal malignancy were randomized to receive insulin (0.11 +/- 0.05 units/kg/d) plus best available palliative support [anti-inflammatory treatment (indomethacin), prevention of anemia (recombinant erythropoietin), and specialized nutritional care (oral supplements + home parenteral nutrition)] according to individual needs. Control patients received the best available palliative support according to the same principles. Health-related quality of life, food intake, resting energy expenditure, body composition, exercise capacity, metabolic efficiency during exercise, and spontaneous daily physical activity as well as blood tests were evaluated during follow-up (30-824 days) according to intention to treat. RESULTS: Patient characteristics at randomizations were almost identical in study and control groups. Insulin treatment for 193 +/- 139 days (mean +/- SD) significantly stimulated carbohydrate intake, decreased serum-free fatty acids, increased whole body fat, particularly in trunk and leg compartments, whereas fat-free lean tissue mass was unaffected. Insulin treatment improved metabolic efficiency during exercise, but did not increase maximum exercise capacity and spontaneous physical activity. Tumor markers in blood (CEA, CA-125, CA 19-9) did not indicate the stimulation of tumor growth by insulin; a conclusion also supported by improved survival of insulin-treated patients (P<0.03). CONCLUSION: Insulin is a significant metabolic treatment in multimodal palliation of weight-losing cancer patients. 相似文献

BACKGROUND: The role of nutrition in the palliative treatment of patients with malignancy-related cachexia is unclear. The goal of the current study was to determine whether specialized, nutrition-focused patient care could improve integrated whole-body metabolism and functional outcome in unselected weight-losing patients with malignant disease who were receiving systemic antiinflammatory (cyclooxygenase [COX]-inhibitory) treatment along with erythropoietin (EPO) support. METHODS: Three hundred nine patients with malignant disease who experienced progressive cachexia due to solid tumors (primarily gastrointestinal lesions) were randomized to receive a COX inhibitor (indomethacin, 50 mg twice daily) and EPO (15-40,000 units per week) along with specialized, nutrition-focused patient care (oral nutritional support and home total parenteral nutrition [TPN]) provided on a patient-by-patient basis to attenuate inflammation, prevent anemia, and improve nutritional status. Control patients received the same indomethacin and EPO doses that study patients received without the added nutritional support. All patients were treated and followed until death. Biochemical assays (blood, liver, kidney, and thyroid), nutritional state assessment (food intake and body composition), and exercise testing with simultaneous measurement of whole-body respiratory gas exchange before and during exercise were performed before the start of treatment and then at regular intervals during the treatment period (every 2-30 months after treatment initiation). Statistical analyses were performed on 'intention-to-treat' and 'as-treated' bases. RESULTS: Home TPN was provided to approximately 50% of the study patients without severe complications. Over the entire observation period, rhEPO prevented the development of anemia in both study patients and control patients. Intention-to-treat analysis revealed an improvement in energy balance for nutritionally supported patients (P < 0.03); no other significant differences in outcome between study patients and control patients were observed. As-treated analysis demonstrated that patients receiving nutrition experienced prolonged survival (P < 0.01), which was accompanied by improved energy balance (P < 0.001), increasing body fat (P < 0.05), and a greater maximum exercise capacity (P < 0.04). A trend toward increased metabolic efficiency at maximum exercise (P < 0.06) for study patients relative to control patients also was observed. CONCLUSIONS: The results of the current study strongly support that nutrition is a limiting factor influencing survival and that nutritional support protects integrated metabolism and metabolic function in patients with progressive cachexia secondary to malignant disease. 相似文献

BACKGROUND: The serum erythropoietin level increases markedly during
chemotherapy for leukemia. A number of hypotheses have been built for the
mechanism, none of them satisfactory. Difficulty in evaluating bone marrow
activity hampers the elucidation. Therefore, we focused on patients who had
non-hematological cancer and no evidence of bone marrow suppression.
METHODS: Twelve patients, who had lung cancer (four with small cell cancer
and eight with non-small cell cancer) and who had not undergone any
chemotherapy, were studied. During chemotherapy, we measured serum
erythropoietin, serum iron, unsaturated iron binding capacity and
hemoglobin concentration in these patients. RESULTS: The serum
erythropoietin level before chemotherapy (10.8 +/- 7.4 mU/ml) was within
the normal range but the peak values after the first treatment (73.4 +/-
90.4 mU/ml) increased in all patients. In the patients with small cell
cancer, a transient but marked increase in erythropoietin value (204.6 +/-
167.3 mU/ml) was observed after each session of chemotherapy while
hemoglobin concentration decreased gradually. Throughout treatments,
elevation of the serum iron concentration and concomitant reduction of
unsaturated iron binding capacity were observed after each session of
chemotherapy. They regained their original values whilst the serum
erythropoietin level decreased after each chemotherapy session was
completed. CONCLUSIONS: It is suggested that the suppression of erythroid
marrow by chemotherapeutic agents causes the changes in serum
erythropoietin level during chemotherapy in patients with lung cancer.

Anemia is common in patients with hematological malignancy. Most patients will have their anemia attributed to the anemia of chronic disease. The anemia of chronic disease is caused by cytokine mediated suppression of erythropoiesis and low serum erythropoietin levels are found in the majority of patients with cancer. Many of these anemic patients will be symptomatic with fatigue. Data from many studies indicates that treatment of anemic patients with erythropoietin will increase their hemoglobin concentration, decrease transfusion need and also improve their quality of life. A recent study also suggests that improving the hemoglobin level may improve the patients' prognosis but this finding needs to be confirmed. 相似文献

PURPOSE: To systematically review the methodologic quality of, and summarize the evidence from trials examining the effectiveness of physical exercise in improving the level of physical functioning and psychological well-being of cancer patients during and after medical treatment. METHODS: Thirty-four randomized clinical trials (RCTs) and controlled clinical trials were identified, reviewed for substantive results, and assessed for methodologic quality. RESULTS: Four of 34 trials met all (seven of seven) methodologic criteria on the Delphi criteria list. Failure to conceal the sequencing of treatment allocation before patient recruitment, failure to blind the outcome assessor, and failure to employ an intention-to-treat analysis strategy were the most prevalent methodologic shortcomings. Various exercise modalities have been applied, differing in content, frequency, intensity, and duration. Positive results have been observed for a diverse set of outcomes, including physiologic measures, objective performance indicators, self-reported functioning and symptoms, psychological well-being, and overall health-related quality of life. CONCLUSION: The trials reviewed were of moderate methodologic quality. Together they suggest that cancer patients may benefit from physical exercise both during and after treatment. However, the specific beneficial effects of physical exercise may vary as a function of the stage of disease, the nature of the medical treatment, and the current lifestyle of the patient. Future RCTs should use larger samples, use appropriate comparison groups to rule out the possibility of an attention-placebo effect, use a comparable set of outcome measures, pay greater attention to issues of motivation and adherence of patients participating in exercise programs, and examine the effect of exercise on cancer survival. 相似文献

Background Performance status (PS) scoring systems are tools of immense clinical importance in the management of patients with malignant
disease but these tools are subjective and do not provide an objective evaluation of physical functioning. We conducted a
pilot study to explore the feasibility and clinical utility of functional capacity testing to assess physical functioning
in recurrent primary malignant glioma patients. Patients and methods Using a cross-sectional design, consecutive patients with recurrent glioma performed a six minute walk (6MW) test to assess
functional capacity. Performance status was assessed using Karnofsky Performance Status (KPS) scoring system. QOL was assessed
by the Functional Assessment of Cancer Therapy-Brain scale. Self-reported exercise behavior was assessed using the Godin Leisure
Time Exercise Questionnaire (GLTEQ). Results A total of 171 patients were recruited and tested. Seventy percent were diagnosed with glioblastoma multiforme (WHO grade
IV) and 85% were undergoing therapy. Median KPS was 90% (range, 70–100%). Median 6MW distance was 400 m (range, 102–630 m),
equivalent to 56 ± 13% (range, 14–87%) of that predicted for age and sex. KPS, self-reported exercise, and QOL increased across
6MW distance quartiles (P < 0.05) although there was considerable variation within each category. 6MW distance and KPS were significantly correlated
with each other (r = 0.34, P < 0.01) and several QOL domains (range, r = −0.43 to 0.46, P < 0.05). Conclusions 6MW distance is a clinically feasible tool that provides an objective measure of physical functioning in select patients
with recurrent glioma. Further research is required to investigate the prognostic value of these tests in patients with advanced
malignancy. 相似文献

PURPOSE: To evaluate daily physical-rest activities in cancer patients losing weight in relation to disease progression. EXPERIMENTAL DESIGN: Physical activity-rest rhythms were measured (ActiGraph, armband sensor from BodyMedia) in relation to body composition (dual-energy X-ray absorptiometry), energy metabolism, exercise capacity (walking test), and self-scored quality of life (SF-36, Hospital Anxiety and Depression Scale) in weight-losing outpatients with systemic cancer (71 +/- 2 years, n = 53). Well-nourished, age-matched, and previously hospitalized non-cancer patients served as controls (74 +/- 4 years, n = 8). Middle-aged healthy individuals were used as reference subjects (49 +/- 5 years, n = 23). RESULTS: Quality of life was globally reduced in patients with cancer (P < 0.01), accompanied by significantly reduced spontaneous physical activity during both weekdays and weekends compared with reference subjects (P < 0.01). Spontaneous physical activity declined over time during follow-up in patients with cancer (P < 0.05). However, overall physical activity and the extent of sleep and bed-rest activities did not differ between patients with cancer and age-matched non-cancer patients. Spontaneous physical activity correlated weakly with maximum exercise capacity in univariate analysis (r = 0.41, P < 0.01). Multivariate analysis showed that spontaneous physical activity was related to weight loss, blood hemoglobin concentration, C-reactive protein, and to subjectively scored items of physical functioning and bodily pain (SF-36; P < 0.05-0.004). Anxiety and depression were not related to spontaneous physical activity. Patient survival was predicted only by weight loss and serum albumin levels (P < 0.01), although there was no such prediction for spontaneous physical activity. CONCLUSIONS: Daily physical-rest activities represent variables which probably reflect complex mental physiologic and metabolic interactions. Thus, activity-rest monitoring provides a new dimension in the evaluation of medical and drug interventions during palliative treatment of patients with cancer. 相似文献

The effects of pain severity on health-related quality of life: a study of Chinese cancer patients. 总被引:7,自引:0,他引:7

BACKGROUND: The health-related functioning of patients with cancer is compromised by several factors, including the disease process, treatment, and the various symptoms that are produced by both disease and treatment. This study was designed to specify the relationship between patients' pain severity and their self-reported quality of life. METHODS: The study enrolled 216 consecutive consenting adult patients from 2 Chinese cancer centers with pathologically-diagnosed metastatic cancer who could understand and complete the self-report measures. The majority had cancer-related pain and were receiving analgesics. The Chinese version of the Brief Pain Inventory was used to assess the severity and interference of pain. A Chinese translation of the Medical Outcomes Study 36-Item Short-Form Health Survey (SF-36) was used to assess health-related functional status. Patients' physicians completed a form that indicated characteristics of the patients' cancer, Eastern Cooperative Oncology Group performance status, pain, and current pain treatment. RESULTS: Increasing severity of pain was associated with worsening health-related functioning, even when an estimate of disease severity was taken into account. The correlation between pain severity and impairment was nonlinear. The functional health and well-being of cancer patients with no or mild pain was significantly less impaired than that of patients with moderate or severe pain. The impairment of patients with moderate and severe pain did not differ. CONCLUSIONS: Pain severity is an important variable to be taken into account when quality of life outcome measures are considered. The functioning of cancer patients with well-controlled (mild) pain did not differ significantly from that of patients without pain. Providing pain relief should significantly improve the functional status of cancer patients. 相似文献

Objective: This study aimed to investigate how nutrition indicators and physical function may influence Health-related Quality of Life (HRQoL) of breast cancer patients undergoing treatment. Methods: This was a cross sectional study among a total of 163 breast cancer patients. Series of measurements including anthropometry, biochemical, and dietary were employed to assess patients’ nutritional status while physical function was assessed by handgrip strength. HRQoL of patients was determined using European Organization for Research and Treatment of Cancer quality of life questionnaire Core 30 (EORTC-QLQ-C30) version 3.0. Multiple linear regression was used to identify factors associated with HRQoL. Results: Breast cancer patients perceived moderately their overall quality of life (QoL), with the mean global health status (GHS) score of 69.12. Emotional functioning was the poorest functional scale while fatigue was the most distressing symptom presented by the patients. Approximately 20% of patients had low corrected arm muscle area while more than half had low hemoglobin level. More than 90% of patients did not meet the overall dietary recommendation and had poor handgrip strength. Mid-upper arm circumference (MUAC) was associated with GHS (β: 0.906; 95% CI: 0.22, 1.56) and cognitive functioning (β: -1.543; 95% CI: -3.07, -0.01). Handgrip strength was positively associated with most of HRQoL outcomes. Conclusions: Breast cancer patients reported overall good nutritional status and moderate QoL during treatment. Being well-nourished improved HRQoL and handgrip strength could be a potential proxy for functional outcomes as well as overall QoL. 相似文献

In 1986, the European Organization for Research and Treatment (EORTC) initiated a research program to develop an integrated, modular approach for evaluating the quality of life of patients participating in international clinical trials. The questionnaire was designed to measure cancer patients' physical, psychological and social functions. The questionnaire is composed of 5 multiitem scales (physical, role, social, emotional and cognitive functioning) and 9 single items (pain, fatigue, financial impact, appetite loss, nausea/vomiting, diarrhea, constipation, sleep disturbance and quality of life). It was administered to the patients before the initiation of palliative treatment and then once again during the treatment. The validation of the questionnaire took place at Areteion Hospital, while the translation was conducted by the EORTC bureau. The final validation sample consisted of 120 cancer patients. The clinical variable assessed was the performance status. The aim of our study was to assess the applicability of this quality of life measurement on a Hellenic sample of cancer patients receiving palliative care. The results showed that the questionnaire was well accepted in the present patient population. In addition, the questionnaire was found to be useful in detecting the effectiveness of palliative treatment over time. The scale reliability was very good (pretreatment from 0.57-0.79, ontreatment from 0.56-0.75), especially for the functioning scale. In addition, very good validity was found in all the approaches used. Moreover, the factor analysis results in a 6-factor solution that satisfies the criteria of reproducibility, interpretability and confirmatory setting. Performance status showed an improvement (p < 0.0025) during the studied period. These results support that the QLQ-C30 (version 3.0) has proven to be a reliable and valid measure of the quality of life in Greek cancer patients receiving palliative care treatment. 相似文献

OBJECTIVE: The present research paper investigates how cancer patients' monitoring and blunting coping styles are reflected in their communications during their initial radiotherapy consultations and in their evaluations of the consultation. Additionally, it is explored how a patient's disease status (curative versus palliative) influences the effects of his or her cognitive styles. METHODS: The study included 116 oncology patients receiving treatment from eight radiation oncologists. For 56 patients treatment intent was palliative and for the remaining 60 curative. The patients' communicative behaviors were assessed using the Roter Interaction Analysis System (RIAS). Within three days the patients completed a monitoring and blunting inventory and after another six weeks they evaluated the treatment decision and treatment information by postal questionnaire. RESULTS: Monitoring was positively and blunting negatively related to the patient's expression of questions, emotions and decision-making issues. After six weeks 'high monitors' as opposed to 'low monitors' reported having more doubts about the treatment decision and being less satisfied with the information received while 'high blunters' expressed fewer doubts and more satisfaction than 'low blunters' did. Significant associations were all attributable to the palliative treatment group. CONCLUSION: Cancer patients' communicative behaviors vis-à-vis their oncologist hinge on their cognitive styles and an unfavorable disease status enhances the effects. 相似文献

This study focuses on patterns of response between patients with cancer and their spouse caregivers to examine the reliability of spouse informants in research and clinical settings. Thirty dyads (patient with cancer-spouse caregiver couples; total n = 60) were interviewed concurrently in their homes concerning patient functioning, psychologic distress, physical symptoms, caregiver perceptions of patient functioning, and marriage quality. Couples had been married an average of 32 years. Patients had either the lung or colon as their primary cancer site, and one third had metastasis. Correlations between 14 variable pairs and cross-tabulation of scale scores suggest that spouse caregivers agree with patients on objective measures with observable referents (e.g., ability to dress independently). Partners disagree on subjective aspects of patient functioning (e.g., depression, fear of future, and confidence in treatment) and marriage quality. Almost without exception, caregivers viewed patients' functioning more negatively than patients described themselves. Patients, however, viewed marital quality more negatively than did caregivers. It was concluded that caregivers can serve as proxies for patients with cancer in research and clinical settings when objective data are sought. Data from both spouses are needed, however, to complete the picture of subjective illness experiences in patients with cancer, including perceptions of pain and disease symptoms. 相似文献

Exercise and rehabilitation approaches in palliative care programs for cancer patients affect patients’ symptoms, physical functioning, muscle strength, emotional wellbeing, psychological symptoms, functional capacities, quality of life, mortality and morbidity positively. Based on scientific data, palliative cancer patients should be recommended to participate in exercise programs. There is no standard approach to recipe an exercise regimen for a palliative cancer survivor. Studies for demonstrating the positive effects of exercising in palliative care patients are increasing in number day by day. At this point, increasing awareness about exercising in the entire team monitoring the patient and our efforts in this matter seems to be very important. 相似文献

Thirty-nine patients with advanced bladder cancer received pelvic radiotherapy (3 Gy x 10 during 2 weeks) with palliative aim. Except for improvement of urinary incontinence, no improvement regarding urinary symptoms or general well-being could be demonstrated in 19 completely evaluable patients who were assessed by a mailed questionnaire 3 months after treatment. The median survival for all 39 patients was 7.5 months. Other forms of palliative treatment (chemotherapy combined with radiotherapy or accelerated radiotherapy, palliative surgery) should be evaluated by randomized trials in these poor-prognosis bladder cancer patients. Self-administrated questionnaires seem to be useful for assessing the subjective morbidity of such patients. 相似文献

PURPOSE: This study investigated (1) the attitudes of cancer patients toward discussing health-related quality-of-life (HRQL) issues; (2) the association between such attitudes and patients' characteristics; and (3) oncologists' attitudes and self-reported behavior regarding these same issues. PATIENTS AND METHODS: Two hundred seventy-three patients receiving palliative chemotherapy and ten physicians were asked to complete a series of questionnaires. RESULTS: Almost all patients wanted to discuss their physical symptoms and physical functioning and were also willing to address their emotional functioning and daily activities. However, 25% of the patients were only willing to discuss these latter two issues at the initiative of their physician. Patients varied most in their willingness to discuss their family and social life, with 20% reporting no interest in discussing these issues at all. Female patients were more reluctant to discuss various HRQL issues than male patients. Older and less well-educated patients were more likely to prefer that their physician initiate discussion of HRQL issues. All physicians considered it to be primarily their task to discuss the physical aspects of their patients' health, whereas four physicians indicated that discussion of psychosocial issues was a task to be shared with other health care providers. All physicians indicated that they generally defer to their patients in initiating discussion of psychosocial issues. CONCLUSION: Although both patients and oncologists seem willing to discuss a wide range of HRQL issues, communication regarding psychosocial issues may be hampered by competing expectations as to who should take the lead in initiating such discussions. 相似文献

PREVOST V. & GRACH M.-C. (2012) European Journal of Cancer Care21, 581-590 Nutritional support and quality of life in cancer patients undergoing palliative care In palliative care, the nutrition provided has to be tailored to the patient's needs, enhancing patient comfort and quality of life (QoL). We conducted a literature search to review methods of measuring QoL, and modalities of nutritional intervention and their influence on QoL of cancer patients in palliative care. Original papers published in English were selected from PubMed database by using the search terms, palliative medicine, cancer, nutrition and quality of life. Specific tools that are particularly recommended to assess QoL in a palliative care setting are reviewed. The main goal in palliative care is to maintain oral nutrition by providing nutritional counselling. Enteral nutritional support showed inconsistent effects on survival and QoL. An evidence-base for parenteral nutrition is still lacking. Ethical considerations concerning provision of food and hydration in end-of-life care are discussed. Nutritional status should be assessed early and regularly during treatment using appropriate tools. In the particularly acute context of palliative care, optimal patient management requires adequate education and counselling to patients and families. Meaningful interactions between the patient, caregivers and medical team would also increase the chance of resolving nutrition-related issues and help to fulfil each patient's specific nutritional needs and thus improve the QoL. 相似文献

PURPOSE: To evaluate the health-related quality of life (HRQOL) and cognitive functioning of high-grade glioma patients in the postneurosurgical period. PATIENTS AND METHODS: The HRQOL, as assessed by the Short-Form Health Survey-36, tumor-specific symptoms, and objective and subjective neuropsychologic functioning, of 68 newly diagnosed glioma patients were compared with that of 50 patients with non-small-cell lung cancer (NSCLC) and to age- and sex-matched healthy controls. The association between tumor lateralization, extent of resection, and use of medication, and the HRQOL outcomes was also investigated. RESULTS: The HRQOL of the two patient groups was similar but significantly lower than that of the healthy controls. Glioma patients reported significantly more neurologic symptoms and poorer objective and subjective neuropsychologic functioning than the NSCLC patients. Using healthy controls as the reference group, cognitive impairment assessed at the individual patient level was observed in all glioma patients and 52% of the NSCLC patients. Poor performance on timed tasks in the glioma group could be attributed, in large part, to visual and motor deficits. Tumor lateralization was found to affect neuropsychologic functioning in a predictable manner. The extent of resection was not related significantly to neuropsychologic functioning. Corticosteroid use was associated with better recognition memory, whereas antiepileptic drug use was correlated negatively with working memory capacity. CONCLUSION: The general HRQOL of glioma patients is similar to that of patients with NSCLC. However, they suffer from a number of condition-specific neurologic and neuropsychologic problems that have a significant impact on their daily lives in the postsurgical period, before treatment with radiotherapy. 相似文献

INTRODUCTION: Hypoxia induced radioresistance has been acknowledged for decades. One of the indirect evidences of the influence of hypoxia on radiation response comes from the observations of a correlation between tumor control and hemoglobin level. This review examines the clinical data on the prognostic and predictive role of hemoglobin level and hemoglobin manipulation in radiotherapy of squamous cell carcinomas of the head and neck, a tumor type where hypoxic radioresistance have been previously documented. THE INFLUENCE OF HEMOGLOBIN CONCENTRATION ON TUMOR OXYGENATION AND OUTCOME: The aim is to evaluate the existing literature for information of the influence of hemoglobin concentration and hemoglobin modifications on tumor oxygenation and outcome in head and neck squamous cell cancer patients. The data from several randomized trials show that while most studies have confirmed the prognostic value of hemoglobin, increasing the hemoglobin level through transfusion or erythropoietin stimulation did not result in improved outcome for patients with low initial hemoglobin levels. Clinical studies showed that smoking reduced the oxygen carrying capacity of the blood through formation of carboxyhemoglobin, and lead to poorer response to radiotherapy in smokers compared to non-smokers. Smoking also increased the risk of the development of secondary cancers. CONCLUSION AND FUTURE PERSPECTIVES: In conclusion, low hemoglobin is a significant negative prognostic factor for radiotherapy of head and neck cancer. Correction of pre-treatment low hemoglobin by blood transfusion and/or erythropoietin stimulating agents does, however, not improve the outcome. Smoking leads to a decrease in effective hemoglobin and poorer treatment outcome. Smoking should be avoided in order to improve the therapeutic efficacy of radiotherapy and development of other smoking-related diseases and/or secondary cancers. 相似文献
