Abstract
Colorectal cancer is the third leading cause of cancer death in Turkey. The emphasis of the healthcare services in Turkey is on curative rather than preventive and rehabilitative approaches. Although the Ministry of Health provides many healthcare services for prevention and early detection, their availability and accessibility are very low. The purpose of this study was to test the reliability and validity of the Turkish language version of Champion's Health Belief Model Scales in measuring Turkish women's and men's beliefs about colorectal cancer. This study was carried out in Izmir, the third most populous city in Turkey. The Champion's Health Belief Model Scales was translated using a back-translation technique. A convenience sample of 470 individuals was recruited from January 2004 through March 2004. Descriptive statistics were computed for the demographic characteristics. Reliability was assessed by interpreting the item-total subscale score correlation, test-retest reliability, and Cronbach alpha coefficients. For testing the relationship between item performance and scale performance, corrected item-total correlations ranged from 0.41 to 0.79 for all 5 subscales. Cronbach alpha coefficients for the 5 subscales ranged between .54 and .88, and test-retest reliability coefficients ranged from 0.72 to 0.91. The study showed that the Turkish version of the Champion's Health Belief Model Scales has good structural characteristics and is a reliable and valid instrument that can be used for measuring beliefs related to colorectal cancer.

Abstract
BACKGROUND Over the past few years there has been a growing interest in the field of physical exercise in rehabilitation of cancer patients, leading to requirements for objective maximum physical capacity measurement (maximum oxygen uptake (VO(2max)) and one-repetition maximum (1RM)) to determine dose-response levels in different cancer diagnoses. AIM To explore the patients' experiences of maximum physical capacity testing while concurrently undergoing chemotherapy and participating in a 6-week, 9 h weekly multidimensional exercise program. DESIGN AND METHOD Prospective, exploratory study using semi-structured qualitative interviews conducted prior to and at termination of the program. The study included 100 patients (18-65 years, median 42 years) with or without residual disease and with mixed diagnoses. RESULTS Following the intervention, cancer patients felt significantly safer in performing maximum physical capacity tests as these motivated them through self-perceived competitiveness and set a standard that served to encourage peak performance. CONCLUSION The positive attitudes in this sample towards maximum physical capacity open the possibility of introducing physical testing early in the treatment process. However, the patients were self-referred and thus highly motivated and as such are not necessarily representative of the whole population of cancer patients treated with chemotherapy.

Abstract
PURPOSE The use of cardiopulmonary exercise testing (CPET) is increasing in many areas of disease management, the clinical utility of this procedure in patients with advanced cancer remains to be determined. Accordingly, we conducted a pilot study to comprehensively evaluate the safety and feasibility of CPET in 85 patients diagnosed with inoperable non-small cell lung cancer (NSCLC) or metastatic breast cancer (MBC). METHODS Using a cross-sectional design, consecutive patients with histologically or cytologically confirmed inoperable NSCLC or MBC were screened for eligibility by their attending oncologist. All consenting patients performed complete pulmonary function tests (NSCLC only) and a symptom-limited CPET on a cycle ergometer with gas exchange analysis. RESULTS A total of 85 patients (NSCLC, n=46; MBC, n=39) were recruited and tested. Overall, there were a total of three (3.5%) positive exercise tests [NSCLC, n=2 (4.3%); MBC, n=1 (2.6%)]; 68 (80.0%) negative tests [NSCLC, n=33 (71.7%); MBC, n=35 (89.7%)]; and 14 (16.5%) indeterminate tests [NSCLC, n=11 (23.3%); MBC, n=3 (7.7%)]. Two patients experienced an adverse event during exercise testing. Mean VO(2peak) was 17.0mlkg(-1)min(-1) and 16.5mlkg(-1)min(-1) for NSCLC and MBC patients, respectively. The mean percentage of age and sex-predicted VO(2peak) maximum for both groups was 67%. CONCLUSION A symptom-limited, individualized CPET appears to be a relatively safe and feasible assessment tool to objectively evaluate physical functioning in selected patients with advanced cancer. This study provides important information to future investigations examining the potential role of exercise training in this patient population.

Abstract
GOALS OF WORK To evaluate a 12-week home-based walking intervention among breast cancer survivors and to quantify changes in physical activity (PA) behaviors, body weight, and body composition in response to the intervention. PATIENTS AND METHODS Breast cancer survivors that were in the posttreatment period were randomized to intervention (n=23) or wait-list usual care (n=13). PA was assessed by self-report, and in a study subsample (n=23), by an accelerometer. Intention to treat principles were employed to estimate the intervention effect on PA behaviors, body weight, and body composition. Intervention adherence was calculated as the proportion of exercise sessions completed relative to the number of exercise sessions recommended, as reported each week on walking logs. MAIN RESULTS Thirty-four of 36 women randomized (94%) completed the study. Average intervention adherence over 12 weeks was 94%. Intervention participants reported a significantly greater increase in walking for exercise [+11.9 metabolic equivalent (MET)-h/week] over time than did usual care participants (+1.7 MET-h/week, p=0.01). Objective measures of activity also indicated that intervention participants increased their activity levels over time as compared to usual care participants [i.e., counts/min/day and steps/day (p< or =0.04)]. No significant changes in body weight or composition were observed. CONCLUSION We found that a 12-week home-based walking intervention was safe and effective for increasing short-term PA levels in breast cancer survivors. Future studies are needed to assess the ability of brief interventions to facilitate the maintenance of increased activity levels and to produce favorable quality of life and risk factor outcomes.

Abstract
Considerable knowledge has accumulated in recent decades concerning the significance of physical activity in the treatment of a number of diseases, including diseases that do not primarily manifest as disorders of the locomotive apparatus. In this review we present the evidence for prescribing exercise therapy in the treatment of metabolic syndrome-related disorders (insulin resistance, type 2 diabetes, dyslipidemia, hypertension, obesity), heart and pulmonary diseases (chronic obstructive pulmonary disease, coronary heart disease, chronic heart failure, intermittent claudication), muscle, bone and joint diseases (osteoarthritis, rheumatoid arthritis, osteoporosis, fibromyalgia, chronic fatigue syndrome) and cancer, depression, asthma and type 1 diabetes. For each disease, we review the effect of exercise therapy on disease pathogenesis, on symptoms specific to the diagnosis, on physical fitness or strength and on quality of life. The possible mechanisms of action are briefly examined and the principles for prescribing exercise therapy are discussed, focusing on the type and amount of exercise and possible contraindications.

Abstract
BACKGROUND Exercise may represent a supportive intervention that may complement existing neurooncologic therapies and address a multitude of therapy-induced debilitating side effects in patients with brain tumors. Given the limited evidence, the authors conducted a survey to examine the exercise patterns of brain tumor patients across the cancer trajectory. METHODS Using a cross-sectional design, 386 brain tumor patients who received treatment at the Brain Tumor Center at Duke University were sent a questionnaire that assessed self-reported exercise behavior prior to diagnosis, during adjuvant therapy, and after the completion of therapy. RESULTS The response rate was 28% (106 of 383 patients). Descriptive analyses indicated that 42%, 38%, and 41% of participants, respectively, met national exercise prescription guidelines prior to diagnosis, during treatment, and after the completion of adjuvant therapy. Repeated measures analyses indicated no significant changes in the majority of exercise behavior outcomes over the cancer trajectory. However, exploratory analyses indicated that males and younger participants may be at the greatest risk of reducing exercise levels after a brain tumor diagnosis. These analyses remained unchanged after controlling for relevant demographic and medical covariates. CONCLUSIONS A relatively high percentage of brain tumor patients are exercising at recommended levels across the cancer trajectory. Moreover, these patients have unique exercise patterns that may be modified by select demographic variables. This preliminary study provides important informative data for future studies examining the potential role of exercise in patients diagnosed with neurologic malignancies.

Abstract
Outcomes assessment in surgery traditionally has included data regarding peri-operative mortality and morbidity, as well as long-term survival and recurrence in surgical oncology. However, quality of life (QOL) is another important patient-related outcome measure. QOL data can be used to tailor treatment and improve clinical outcomes by detecting physical or psychological problems in patients that otherwise might be overlooked, but which have profound implications for the effective delivery of care. We review several well-validated QOL instruments developed specifically for use in patients with gastrointestinal malignancies, including esophageal, pancreatic and colorectal cancers, and conclude that QOL assessment routinely should be included in clinical trials of novel treatments.

Abstract
The purpose of this study was to examine the demographic, medical, and social cognitive determinants of exercise intentions in a population-based sample of multiple myeloma cancer survivors. Using a cross-sectional survey, 70 multiple myeloma cancer survivors completed a questionnaire that assessed their medical and demographic characteristics, past exercise behavior, and social cognitive exercise beliefs using the theory of planned behavior. Seventy participants provided valuable data. Descriptive statistics indicated that participants had quite positive instrumental attitude, intentions, and subjective norms and moderate levels of perceived behavioral control and affective attitudes for exercise. Forced entry multiple regression showed that the theory of planned behavior explained 43% of the variance in exercise intentions. Instrumental attitude and perceived behavioral control were both independent predictors of exercise intentions. No demographic or medical variable moderated the association between the theory of planned behavior constructs and exercise intentions. The results of the present investigation support the growing body of evidence confirming the utility of the theory of planned behavior to understand the salient determinants of exercise in cancer survivors. Knowledge gained from this study provides important information to oncology practitioners who are responsible for delivering supportive care interventions, including exercise, to patients diagnosed with multiple myeloma.

Abstract
AIM: To evaluate the changes of life quality of patients with rectal cancer before and after operation.
METHODS: The life qualities of 48 patients (Dixon: n = 25; Miles: n = 23) with rectal cancer were assessed using gastrointestinal quality of life index (GIQLI) before and 1, 6, 12 mo after operation.
RESULTS: The mean preoperative GIQLI score of all the patients was 104.21. The scores were 91.97 (P < 0.05), 105.65 (P > 0.05), and 113.95 (P < 0.05), respectively, 1, 6 and 12 mo after operation. The GIQLI score of Dixon's group was slightly lower than that of Miles' group 1 mo after operation (P > 0.05), but significantly higher than 6 and 12 months after operation (107.30 ± 10.57 vs 103.85 ± 11.03, P < 0.05; 116.35 ± 12.64 vs 111.34 ± 13.65, P < 0.05).
CONCLUSION: The life quality of patients with rectal cancer falls in the early period after operation due to the damage of operation and complication, but it is significantly improved in the long period, which is related to the operation style.

Abstract
In the present study, we examined the exercise preferences of a population-based sample of non-Hodgkin's lymphoma (NHL) survivors. A secondary purpose was to explore the association between various demographic, medical, and exercise behaviour variables and elicited exercise preferences. Using a retrospective survey design, 431 NHL survivors residing in Alberta, Canada completed a mailed questionnaire designed to assess exercise preferences, past exercise behaviour, and various demographic variables. Overall, 77% of participants preferred or maybe preferred to receive exercise counselling at some point after their NHL diagnosis. An overwhelming majority indicated that they would possibly be interested (81%) and able (85%) to participate in an exercise programme designed for NHL survivors. The majority of participants (55%) listed walking as their preferred choice of exercise. Logistic regression analyses indicated that NHL survivors' exercise preferences were influenced by body mass index (BMI), exercise behaviour, and gender. Eliciting exercise preferences from the population in question yields important information for cancer care professionals designing exercise programmes for NHL survivors. Furthermore, tailoring exercise programmes to the preferences of NHL survivors may be one method to potentially enhance exercise adherence in this population both inside and outside of clinical trials.

Abstract
GOAL This review applied meta-analytic procedures to integrate primary research findings that tested exercise interventions among people treated for cancer. METHODS Extensive literature searching strategies located published and unpublished intervention studies that tested exercise interventions with at least five participants (k = 30). Primary study results were coded. Meta-analytic procedures were conducted. MAIN RESULTS The overall weighted mean effect size (ES) for two-group comparisons was 0.52 (higher mean for treatment than control) for physical function, 0.35 for symptoms other than fatigue, and 0.27 for body composition. More modest positive ESs were documented for mood (0.19), quality of life (0.14), fatigue (0.11), and exercise behavior (0.04). ESs were larger among single-group pre-post design studies. ESs among control group participants were typically negative and not (statistically) significantly different from 0. CONCLUSIONS Exercise interventions resulted in small positive effects on health and well-being outcomes among existing studies. Future research should examine intervention-specific characteristics that result in optimal results, such as dose.

Abstract
BACKGROUND Approximately 9.8 million cancer survivors are alive in the United States today. Enthusiasm for prescribing physical activity for cancer survivors depends on evidence regarding whether physical activity during or after completion of treatment results in improved outcomes such as cardiorespiratory fitness, fatigue, symptoms, quality of life, mental health, or change in body size. METHODS A systematic qualitative and quantitative review of the English language scientific literature identified controlled trials of physical activity interventions in cancer survivors during and after treatment. Data from 32 studies were abstracted, weighted mean effect sizes (WMES) were calculated from the 22 high-quality studies, and a systematic level of evidence criteria was applied to evaluate 25 outcomes. RESULTS There was qualitative and quantitative evidence of a small to moderate effect of physical activity interventions on cardiorespiratory fitness (WMES = 0.51 and 0.65 during and after treatment respectively, P < 0.01), physiologic outcomes and symptoms during treatment (WMES = 0.28, P < 0.01 and 0.39, P < 0.01, respectively), and vigor posttreatment (WMES = 0.83, P = 0.04). Physical activity was well tolerated in cancer survivors during and after treatment, but the available literature does not allow conclusions to be drawn regarding adverse events from participation. CONCLUSIONS Physical activity improves cardiorespiratory fitness during and after cancer treatment, symptoms and physiologic effects during treatment, and vigor posttreatment. Additional physical activity intervention studies are needed to more firmly establish the range and magnitude of positive effects of physical activity among cancer survivors.

Abstract
BACKGROUND The Colorectal Cancer and Home-Based Physical Exercise (CAN-HOPE) trial compared the effects of a 16-week home-based exercise program to usual care on quality of life in colorectal cancer survivors. PURPOSE In this study, we report the weekly exercise barriers from the exercise group. METHODS Participants randomized to the exercise group (N = 69) were asked to report their exercise on a weekly basis by telephone. Those participants not achieving the minimum weekly exercise prescription (3 times per week of 30 min of moderate intensity exercise) were asked for a primary exercise barrier. RESULTS We obtained 1,073 (97.2%) weeks of adherence data out of a possible 1,104 (i.e., 69 x 16). Participants did not meet the minimum exercise prescription in 39.2% (421/1,073) of the weeks. We obtained an exercise barrier in 83.8% (353/421) of these cases. Overall, participants reported 37 different exercise barriers; the three most common were lack of time/too busy, nonspecific treatment side effects, and fatigue. The top 7 to 10 barriers accounted for 70% to 80% of all missed exercise weeks. CONCLUSIONS These findings may have utility for promoting exercise in this population both inside and outside of clinical trials.

Abstract
The purpose of this study was to determine whether the Functional Assessment of Cancer Therapy-Colorectal (the FACT-C), a disease-specific tool for the assessment of colorectal cancer patients' QOL, is a valid assessment tool for measuring QOL changes. Ninety-eight colorectal cancer patients performed the assessment at baseline and 52 of these patients completed the instrument at one month and six months after colectomy. In addition to the FACT-C, the shortened forms of the Profile of Mood States, the Eastern Cooperative Oncology Group Performance Status Rating, Neuroticism Scale in the Eysenck Personality Questionnaire, and Functional Living Index-Cancer were completed. We found convergent and divergent validity and good reliability of the FACT-C. Patients' overall QOL was lower at one month after colectomy and recovered to the pre-surgery level at six months after colectomy.

Abstract
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.

Abstract
The purpose of this study was to examine predictors of exercise adherence (i.e. exercise in the intervention group) and exercise contamination (i.e. exercise in the control group) in a randomized controlled trial of home-based exercise in colorectal cancer survivors. At baseline, 102 participants completed measures of the theory of planned behavior, personality, past exercise, exercise stage of change, physical fitness, and medical/demographics and then were randomly assigned in a 2:1 ratio to an exercise (n=69) or control (n=33) group. Exercise was monitored weekly for 16 weeks using self-reports by telephone. Ninety-three (91%) participants completed the trial. Adherence was 76% in the exercise group and contamination was 52% in the control group. Hierarchical stepwise regression analyses indicated that baseline exercise stage of change (beta=0.35; p=0.001), employment status (beta=-0.28; p=0.010), treatment protocol (beta=-0.26; p=0.018), and perceived behavioral control (beta=0.20; p=0.055) explained 39.6% of the variance in exercise adherence. Intentions (beta=0.36; p=0.049) and baseline exercise stage of change (beta=0.30; p=0.095) explained 29.9% of the variance in exercise contamination. These findings may have implications for conducting clinical trials of exercise in colorectal cancer survivors and for promoting exercise to colorectal cancer survivors outside of clinical trials.

Abstract
GOALS OF THE WORK The goal of this study was to examine the association between exercise and quality of life (QOL) in multiple myeloma cancer survivors. PATIENTS AND METHODS Using a retrospective design, 156 multiple myeloma cancer survivors were mailed a questionnaire that assessed self-reported exercise behavior over three periods (prediagnosis, active treatment, and off-treatment) and QOL. MAIN RESULTS The response rate was 56% (88/ 156). Descriptive analyses indicated that 6.8% and 20.4% of survivors met national exercise guidelines during active and off-treatment periods, respectively. Exercise during active treatment and off-treatment were positively associated with overall QOL and all subdomains of QOL (all P<0.05) except physical wellbeing. CONCLUSIONS A low percentage of multiple myeloma cancer survivors are exercising regularly either during active or off-treatment periods. Survivors who report more exercise during these periods also report higher QOL. These findings suggest that a randomized controlled trial is warranted.

Abstract
The global increase in the number of newly diagnosed cancers has led in most affected countries to increased numbers of cancer survivors, who have specific needs for physical and psychosocial rehabilitation. In spite of recent progress, little is known about the specific rehabilitation measures that could increase the quality of life for cancer survivors. We reviewed published interventions that focussed on changing known risk factors for cancer recurrence and improving physical well-being; those we selected were exercise, smoking, alcohol consumption, diet and the use of sun screens. The published trials varied in the quality of the methods used, often had inadequate sample sizes and showed difficulty in validating outcomes. We conclude that there is still insufficient evidence to assess the importance of these behavioural risk factors in the rehabilitation of cancer patients. Future interventions should be designed to assess the separate effects of dietary changes, exercise and psychosocial interventions.

Abstract
PURPOSE To present an overview of exercise interventions in cancer patients during and after treatment and evaluate dose-training response considering type, frequency, volume, and intensity of training along with expected physiological outcomes. METHODS The review is divided into studies that incorporated cardiovascular training, combination of cardiovascular, resistance, and flexibility training, and resistance training alone during and after cancer management. Criteria for inclusion were based on studies sourced from electronic and nonelectronic databases and that incorporated preintervention and postintervention assessment with statistical analysis of data. RESULTS Twenty-six published studies were summarized. The majority of the studies demonstrate physiological and psychological benefits. However, most of these studies suffer limitations because they are not randomized controlled trials and/or use small sample sizes. Predominantly, studies have been conducted with breast cancer patients using cardiovascular training rather than resistance exercise as the exercise modality. Recent evidence supports use of resistance exercise or "anabolic exercise" during cancer management as an exercise mode to counteract side effects of the disease and treatment. CONCLUSION Evidence underlines the preliminary positive physiological and psychological benefits from exercise when undertaken during or after traditional cancer treatment. As such, other cancer groups, in addition to those with breast cancer, should also be included in clinical trials to address more specifically dose-response training for this population. Contemporary resistance training designs that provide strong anabolic effects for muscle and bone may have an impact on counteracting some of the side effects of cancer management assisting patients to improve physical function and quality of life.

Abstract
The primary purpose of this study was to examine differences in quality of life (QoL) between non-Hodgkin's lymphoma (NHL) survivors meeting and not meeting public health exercise guidelines. A secondary purpose was to examine exercise behavior changes across three distinct cancer-related time periods (i.e. prediagnosis, on treatment and off treatment). Using a retrospective survey design, 438 NHL survivors residing in Alberta, Canada completed a mailed questionnaire that assessed self-reported exercise prediagnosis, on treatment and off treatment, and current QoL. Descriptive analyses indicated that 33.8, 6.5 and 23.7% of NHL survivors met public health exercise guidelines during prediagnosis, on treatment, and off treatment time periods, respectively. Multivariate analyses of variance indicated that NHL survivors meeting public health exercise guidelines during postdiagnosis time periods had higher current QoL scores than NHL survivors not meeting guidelines. QoL difference scores between the two groups met proposed standards for clinically important differences. Multivariate analyses also indicated significant differences in exercise behavior across the three cancer-related time periods (all p's<0.01). These analyses were unchanged after statistically controlling for important medical and demographic variables. The results of this study provide evidence that NHL survivors meeting public health exercise guidelines on and off treatment reported higher current QoL than those survivors not meeting guidelines. These findings corroborate research examining exercise behavior in other cancer survivor groups and provide preliminary data to support a randomized controlled trial on exercise and QoL in this population.

Abstract
OBJECTIVE To systematically review controlled trials investigating the effects of exercise interventions in cancer patients. METHODS Studies were located through searching seven electronic databases (Medline, Embase, Cochrane Library, CancerLit, PsycInfo, Cinahl, SportDiscus), scanning reference lists of relevant articles, contacting experts (n = 20), and checking the contents lists of journals available through ZETOC (Electronic Table of Contents). To be included, trials had to be prospective, controlled, involve participants diagnosed with cancer and test an exercise intervention. Types of outcome were not restricted. Two reviewers independently applied the selection criteria. RESULTS Thirty-three controlled trials (including 25 randomized trials) were included in the review. There was some evidence that physical function was increased among those who exercised. Furthermore, symptoms of fatigue did not appear to be increased and there were few adverse effects reported. There was insufficient evidence to determine effects on other outcomes, such as quality of life, with results hampered by the heterogeneity between studies as well as poor methodological quality. Data were also lacking on the long term effects of exercise relating to cancer recurrence or survival. CONCLUSIONS There is preliminary evidence that exercise interventions for cancer patients can lead to moderate increases in physical function and are not associated with increased symptoms of fatigue. However, it is impossible from current evidence to determine whether exercise has long term beneficial effects on survival or quality of life.

Abstract
OBJECTIVE To examine predictors of adherence in a randomized controlled trial of resistance exercise training (RET) in prostate cancer survivors receiving androgen deprivation therapy. STUDY DESIGN AND SETTING A randomized controlled trial conducted at fitness centers in Ottawa and Edmonton, Canada. Prostate cancer survivors (n=155) completed measures of social cognitive variables, quality of life (QOL), behavior, and fitness before being randomized to either an exercise (n=82) or control (n=73) group. The exercise group was asked to perform supervised RET three times per week for 12 weeks. RESULTS The exercise group attended 28.2 of the 36 (78.3%) RET sessions. Univariate analyses revealed eight different significant (Ps <.05) predictors of exercise adherence including exercise stage of change, intention, age, QOL, fatigue, subjective norm, leg-press test, and perceived behavioral control. A multivariate analysis indicated that there were three independent predictors of adherence that explained 20.4% of the variance: exercise stage of change (beta=0.26; P=.013), age (beta=-0.22; P=.037), and intention (beta=0.19; P=.073). CONCLUSION Exercise adherence in the trial was very good but not optimal. Adherence was predicted by variables from many different categories including social cognitive, QOL, behavioral, fitness, and demographic. These findings may have important implications for maximizing adherence during clinical trials of exercise in prostate cancer survivors.

Abstract
Exercise has been widely believed to be a preventive and therapeutic aid in the treatment of various pathophysiological conditions such as cardiovascular disease and cancer. A common problem associated with such pathologies is cachexia, characterized by progressive weight loss and depletion of lean and fat body mass, and is linked to poor prognosis. As this syndrome comprises changes in many physiological systems, it is tempting to assume that the modulation of the psychoneuroimmunoendocrine axis could attenuate or even prevent cachexia progression in cancer patients. Cancer cachexia is characterized by a disruption in the rhythmic secretion of melatonin, an important time-conditioning effector. This hormone, secreted by the pineal gland, transmits circadian and seasonal information to all organs and cells of the body, synchronizing the organism with the photoperiod. Considering that exercise modulates the immune response through at least two different mechanisms-metabolic and neuroendocrine-we propose that the adoption of a regular exercise program as a complementary strategy in the treatment of cancer patients, with the exercise bouts regularly performed at the same time of the day, will ameliorate cachexia symptoms and increase survival and quality of life.

Abstract
Neurofibromatosis is a neurocutaneous systemic disease that occurs in 1:2500 to 3300 live births. Prevalence figures have shown it to be as common as cystic fibrosis or Down's syndrome and more than twice as common as muscular dystrophy. In this study, our experience with 257 cases of neurofibromatosis seen since 1972 is reviewed. Intracranial, bony, and extracranial anomalies are described in the 223 patients (87%) who presented with, or ultimately developed, head and neck manifestations of the disease. The most common intracranial tumor was optic glioma, found in 35 patients (14%), 19 younger than 10 years of age. Acoustic neuromas were diagnosed in eight individuals (3%) and were bilateral in three. The most common skull anomaly was macrocephaly, noted 78 times (30%). Absence of the sphenoid wing occurred in 11 patients (4%) and 19 others (7%) had facial asymmetry due to other skull abnormalities. Extracranial manifestations included neurofibromas of the plexiform and nonplexiform type, Lisch nodules, and cafe-au-lait spots.
