Stop Flow in abdominal and pelvic cancer relapses.
To determinate MTD, DLT and safe doses for phase II study, a dose finding study with Mitomycin and Adriamycin Stop-Flow administration was carried out. A phase II study focused on resectability of pelvic colorectal relapses is in progress. From November 1995, 84 pts, 52 male and 32 female (94 treatments), with advanced not resectable abdominal (14 pts) or pelvic (70 pts) relapses, and resistant to previous systemic chemotherapy, were enrolled in the study. 46 pts entered the phase I-early phase II study, while subsequently 38 pts were recruited in ongoing phase II study. Safe dose were: MMC 20 mg/mq and ADM 75 mg/mq. The phase II study focused on colorectal relapses registered very promising responses: 90% pain control, 1 pCR and 26 PR / 63 (OR 43%), 8 NC (13%) 9/27 responder patients (33%) obtained a complete resectability of colorectal relapses. Stop-Flow is a safe and feasible technique very useful as a palliation treatment.

Efficacy of l-carnitine administration on fatigue, nutritional status, oxidative stress, and related quality of life in 12 advanced cancer patients undergoing anticancer therapy.
OBJECTIVE: Fatigue is a multidimensional symptom that is described in terms of perceived energy, mental capacity, and psychological status: it can impair daily functioning and lead to negative effects on quality of life. It is one of the most common side effects of chemotherapy and radiotherapy. In recent studies, l-carnitine (LC) supplementation has been demonstrated to be able to improve fatigue symptoms in patients with cancer. METHODS: In the present study we tested the efficacy and safety of LC supplementation in a population of patients who had advanced cancer and developed fatigue, high blood levels of reactive oxygen species, or both. As outcome measures we evaluated fatigue and quality of life in relation to oxidative stress, nutritional status, and laboratory variables, mainly levels of reactive oxygen species, glutathione peroxidase, and proinflammatory cytokines. From March to July 2004, 12 patients who had advanced tumors (50% at stage IV) at different sites were enrolled (male-to-female ratio 2:10, mean age 60 y, range 42-73). Patients were only slightly anemic (hemoglobin 10.9 g/dL) and hemoglobin levels did not change after treatment. LC was administered orally at 6 g/d for 4 wk. All patients underwent antineoplastic treatment during LC supplementation. RESULTS: Fatigue, as measured by the Multidimensional Fatigue Symptom Inventory-Short Form, decreased significantly, particularly for the General and Physical scales, and for quality of life in each subscale of quality of life in relation to oxidative stress. Nutritional variables (lean body mass and appetite) increased significantly after LC supplementation. Levels of reactive oxygen species decreased and glutathione peroxidase increased but not significantly. Proinflammatory cytokines did not change significantly. CONCLUSION: Improvement of symptoms with respect to fatigue and quality of life in relation to oxidative stress may be explained mainly by an increase in lean body mass, which may be considered the most important nutritional or functional parameter in assessing the cachectic state of patients. In this view, fatigue with related symptoms can well be considered an important constituent of cancer-related anorexia cachexia syndrome.

A phase II study with antioxidants, both in the diet and supplemented, pharmaconutritional support, progestagen, and anti-cyclooxygenase-2 showing efficacy and safety in patients with cancer-related anorexia/cachexia and oxidative stress.
PURPOSE: To test the efficacy and safety of an integrated treatment based on a pharmaconutritional support, antioxidants, and drugs, all given orally, in a population of advanced cancer patients with cancer-related anorexia/cachexia and oxidative stress. PATIENTS AND METHODS: An open early-phase II study was designed according to the Simon two-stage design. The integrated treatment consisted of diet with high polyphenols content (400 mg), antioxidant treatment (300 mg/d alpha-lipoic acid + 2.7 g/d carbocysteine lysine salt + 400 mg/d vitamin E + 30,000 IU/d vitamin A + 500 mg/d vitamin C), and pharmaconutritional support enriched with 2 cans per day (n-3)-PUFA (eicosapentaenoic acid and docosahexaenoic acid), 500 mg/d medroxyprogesterone acetate, and 200 mg/d selective cyclooxygenase-2 inhibitor celecoxib. The treatment duration was 4 months. The following variables were evaluated: (a) clinical (Eastern Cooperative Oncology Group performance status); (b) nutritional [lean body mass (LBM), appetite, and resting energy expenditure]; (c) laboratory [proinflammatory cytokines and leptin, reactive oxygen species (ROS) and antioxidant enzymes]; (d) quality of life (European Organization for Research and Treatment of Cancer QLQ-C30, Euro QL-5D, and MFSI-SF). RESULTS: From July 2002 to January 2005, 44 patients were enrolled. Of these, 39 completed the treatment and were assessable. Body weight increased significantly from baseline as did LBM and appetite. There was an important decrease of proinflammatory cytokines interleukin-6 (IL-6) and tumor necrosis factor-alpha, and a negative relationship worthy of note was only found between LBM and IL-6 changes. As for quality of life evaluation, there was a marked improvement in the European Organization for Research and Treatment of Cancer QLQ-C30, Euro QL-5D(VAS), and multidimensional fatigue symptom inventory-short form scores. At the end of the study, 22 of the 39 patients were "responders" or "high responders." The minimum required was 21; therefore, the treatment was effective and more importantly was shown to be safe. CONCLUSION: The efficacy and safety of the treatment have been shown by the study; therefore, a randomized phase III study is warranted.

Evaluation of the effectiveness of treatment with erythropoietin on anemia, cognitive functioning and functions studied by comprehensive geriatric assessment in elderly cancer patients with anemia related to cancer chemotherapy.
The primary aim of the present study was to examine the relationship of changes in hemoglobin levels following recombinant human erythropoietin (rHuEPO) treatment to changes in cognitive functioning studied by Mini Mental State Examination (MMSE) in elderly cancer patients undergoing chemotherapy treatment. The secondary aim was that to assess the relationship of changes in hemoglobin levels following rHuEPO treatment to changes in functions studied by Comprehensive Geriatic Assessment (CGA), such as Activity of Daily Living (ADL), Instrumental Activities of Daily Living (IADL), Geriatric Depression Scale (GDS) and the Mini Nutritional Assessment (MNA). To this end, hemoglobin levels and cognitive functioning were evaluated in a sample of cancer patients prior to the start of chemotherapy treatment and again after 4, 8 and 12 weeks of treatment with chemotherapy plus rHuEPO. Ten elderly patients (mean age 71.4 years) were enrolled. At baseline, enrolled patients had a mean Hb value of 10.3g/dl. After 4 weeks of rHuEPO treatment, Hb values increased significantly (p<0.0001), with a mean increase of 1.2g/dl (range: 0.2-2.1). Remarkably, 8 out of 10 (80%) showed an increase of Hb levels >or=1g/dl in comparison to baseline and therefore were considered responders. At baseline, four patients (40%) showed a moderate cognitive impairment, whilst six patients (60%) showed a normal cognitive function. After 4 weeks of rHuEPO treatment nine patients (90%) showed a significant improvement of cognitive functions in comparison to baseline (p<0.005): eight of them were responders also to rHuEPO in terms of correction of anemia. The Spearman's rank correlation test showed a statistical significant correlation between Hb increase and increase in cognitive functioning assessed by MMSE after 4 weeks (p=0.049), 8 weeks (p=0.044) and 12 weeks (p=0.031) of rHuEPO treatment. Therefore, the findings of this study provide support for the hypothesis that significant increases in hemoglobin over the course of chemotherapy supplemented with rHuEPO administration would be accompanied by significant improvement in cognitive performance over the same interval.

Hemoglobin levels correlate with interleukin-6 levels in patients with advanced untreated epithelial ovarian cancer: role of inflammation in cancer-related anemia.
Anemia occurs in more than 30% of patients with epithelial ovarian cancer before any surgery. High levels of proinflammatory cytokines and increased oxidative stress may contribute to the development of cancer-related anemia. We assessed a population of previously untreated patients with advanced epithelial ovarian cancer to evaluate whether there was a correlation between hemoglobin (Hb) and parameters of inflammation and oxidative stress, stage of disease, and performance status (PS). In 91 patients with epithelial ovarian cancer and 95 healthy women matched for age, weight, and height, levels of Hb, C-reactive protein (CRP), fibrinogen (Fbg), proinflammatory cytokines, leptin, reactive oxygen species (ROS), and antioxidant enzymes were assessed at diagnosis before treatment. The correlations between Hb, parameters of inflammation and oxidative stress, stage, and PS were evaluated. Hb levels were lower in patients with advanced epithelial ovarian cancer than in control subjects and inversely related to stage and PS. Hb negatively correlated with CRP, Fbg, interleukin 1beta (IL-1beta), IL-6, tumor necrosis factor alpha (TNFalpha), and ROS, and positively correlated with leptin and glutathione peroxidase (GPx). Multivariate regression analysis showed that stage and IL-6 were independent factors determining Hb values. This evidence suggests that anemia in epithelial ovarian cancer is common and its presence is related to stage of disease and markers of inflammation.

Branched-chain amino acids: the best compromise to achieve anabolism?
PURPOSE OF REVIEW: The anorexia-cachexia syndrome is highly prevalent in patients suffering from acute and chronic diseases, including cancer, chronic renal failure and liver cirrhosis. Once it has developed, it significantly influences the clinical course of the underlying disease, simultaneously impinging on patients' quality of life. Unfortunately, currently available therapeutic strategies do not appear to greatly impact on patients' morbidity, mortality and quality of life. More effective therapies are needed to promote appetite and food intake, to preserve lean body mass, and to ameliorate patients' psychological distress. RECENT FINDINGS: Branched-chain amino acids are neutral amino acids with interesting and clinically relevant metabolic effects. Their potential role as antianorexia and anticachexia agents was proposed many years ago, but only recent experimental studies and clinical trials have tested their ability to stimulate food intake and counteract muscle wasting in anorectic, weight-losing patients. By interfering with brain serotonergic activity and by inhibiting the overexpression of critical muscular proteolytic pathways, branched-chain amino acids have been shown to induce beneficial metabolic and clinical effects under different pathological conditions. SUMMARY: Based on the available data, branched-chain amino acids appear to exert significant antianorectic and anticachectic effects, and their supplementation may represent a viable intervention not only for patients suffering from chronic diseases, but also for those individuals at risk of sarcopenia due to age, immobility or prolonged bed rest, including trauma, orthopedic or neurologic patients.

Ghrelin, appetite, and gastric motility: the emerging role of the stomach as an endocrine organ.
Recent progress in the field of energy homeostasis was triggered by the discovery of adipocyte hormone leptin and revealed a complex regulatory neuroendocrine network. A late addition is the novel stomach hormone ghrelin, which is an endogenous agonist at the growth hormone secretagogne receptor and is the motilin-related family of regulatory peptides. In addition to its ability to stimulate GH secretion and gastric motility, ghrelin stimulates appetite and induces a positive energy balance leading to body weight gain. Leptin and ghrelin are complementary, yet antagonistic, signals reflecting acute and chronic changes in energy balance, the effects of which are mediated by hypothalamic neuropeptides such as neuropeptide Y and agouti-related peptide. Endocrine and vagal afferent pathways are involved in these actions of ghrelin and leptin. Ghrelin is a novel neuroendocrine signal possessing a wide spectrum of biological activities that illustrates the importance of the stomach in providing input into the brain. Defective ghrelin signaling from the stomach could contribute to abnormalities in energy balance, growth, and associated gastrointestinal and neuroendocrine functions.

Association of serum IL-6 levels with comprehensive geriatric assessment variables in a population of elderly cancer patients.
The primary aim of this study was to find whether any association exists between serum levels of proinflammatory cytokines, mainly IL-6, and the most important comprehensive geriatric assessment (CGA) variables such as functional status, cognitive functions and nutrition in a population of elderly cancer patients. The secondary aims were to find whether any difference existed between: i) age groups, ii) performance status scores, iii) patients who had lost weight versus those who had not. Eighty-four elderly patients with advanced cancer were included in the study (stage III 15.4%, and stage IV 72.6%). Serum levels of IL-6 and CRP were significantly higher in elderly than in the other adult cancer patients. Among the CGA variables investigated, the most affected were functional status assessed by IADL, cognitive functions by MMSE and nutrition. The ECOG PS was shown to be significantly associated with all the dimensions of CGA investigated: poor PS (>/=2) corresponded to severe disabilities. As for the relationship of serum IL-6 with CGA variables, the strongest correlations were between IL-6 and functional status assessed by both Katz ADL (p=0.0003), IADL (p=0.0070) and nutrition (p=0.0013). Moreover, we observed an association, although not statistically significant, between functional disability (ADL and IADL) and high IL-6 levels in individuals with weight loss. IL-6 levels seem to be independently associated with all CGA variables investigated in the present study in a population of elderly cancer patients. Because the most important CGA variables, in particular functional status, have been observed to be strongly associated with survival, the present study, confirming our previously reported ones, suggests that IL-6 may be a reliable marker of disease outcome and supports the feasibility of using IL-6 as a sensitive outcome marker in studies based on novel approaches aiming at modifying age- and cancer-related biologic mechanisms.

Selenium is effective in inducing lymphocyte progression through cell cycle in cancer patients: potential mechanisms for its activity.
Epidemiologic evidence in humans suggests a role for selenium in reducing cancer incidence and mortality. The aim of the present study was that to assess the ability of selenium dioxide (SeO2) to enhance the lymphocyte progression through the cell cycle in patients with advanced (stage IV) cancer. Ten patients (mean age 51.9 years, range: 32-74; M/F ratio: 3/7) with tumors at different sites were included in the study. The addition into culture of SeO2 1.5 microM enhanced significantly the progression into S phase of PBMCs isolated from cancer patients, whilst no significant effect was observed on PBMCs isolated from controls. ROS levels were significantly higher, whereas GPx activity was significantly lower in cancer patients than controls. Serum levels of IL-6 and TNFalpha were significantly higher in cancer patients than controls. Our results show the ability of selenium to induce a progression of PBMCs from cancer patients into the cell cycle, which is an essential prerequisite for the physiological functioning of the immune system and thus positively influence the immune status of advanced cancer patients. The mechanism of action of selenium could be to downregulate the production and release of proinflammatory cytokines, which have a role in cancer progression and particularly in the onset of cachexia.

Cancer-related anorexia/cachexia syndrome and oxidative stress: an innovative approach beyond current treatment.
OBJECTIVE: Cancer-related anorexia/cachexia syndrome and oxidative stress play a key role in the progression and outcome of neoplastic disease. PATIENTS AND METHODS: On the basis of our previously published studies and clinical experience, we have developed an innovative approach consisting of diet with high polyphenol content (400 mg), p.o. pharmaconutritional support enriched with n - 3 fatty acids (eicosapentaenoic acid and docosahexaenoic acid) 2 cans (237 mL each) per day, medroxiprogesterone acetate 500 mg/d, antioxidant treatment with alpha-lipoic acid 300 mg/d plus carbocysteine lysine salt 2.7 g/d plus vitamin E 400 mg/d plus vitamin A 30,000 IU/d plus vitamin C 500 mg/d, and selective cyclooxygenase-2 inhibitor Celecoxib 200 mg/d. The treatment is administered for 16 weeks. The following variables are evaluated: (a) clinical variables (stage and Eastern Cooperative Oncology Group performance status); (b) nutritional variables (lean body mass, appetite, and resting energy expenditure); (c) laboratory variables (serum levels of proinflammatory cytokines, C-reactive protein, and leptin and blood levels of reactive oxygen species and antioxidant enzymes); and (d) quality of life variables (European Organization for Research and Treatment of Cancer QLQ-C30, EQ-5Dindex, and EQ-5DVAS). A phase II nonrandomized study has been designed to enroll 40 patients with advanced cancer at different sites with symptoms of cancer-related anorexia/cachexia syndrome and oxidative stress. RESULTS: As of January 2004, 28 patients have been enrolled: 25 patients were evaluable and 14 of them have completed the treatment (20 patients have completed 2 months of treatment). As for clinical response, five patients improved, three patients remained unchanged, and six patients worsened. The Eastern Cooperative Oncology Group performance status (grade) 1 remained unchanged. As for nutritional/functional variables, the lean body mass increased significantly at 2 and 4 months. As for laboratory variables, reactive oxygen species decreased significantly and proinflammatory cytokines interleukin-6 and tumor necrosis factor-alpha decreased significantly. As for quality of life, it comprehensively improved after treatment. CONCLUSIONS: The treatment has been shown to be effective for clinical response, increase of lean body mass, decrease of reactive oxygen species and proinflammatory cytokines, and improvement of quality of life. The treatment has been shown to be safe with good compliance of patients. The study is in progress (14 further patients will be included).

Antioxidant agents are effective in inducing lymphocyte progression through cell cycle in advanced cancer patients: assessment of the most important laboratory indexes of cachexia and oxidative stress.
This study assessed in a wide population of advanced cancer patients the biological parameters relevant to cancer cachexia, such as serum levels of proinflammatory cytokines (IL-1beta, IL-6, TNFalpha), IL-2, acute-phase proteins (C-reactive protein and fibrinogen), leptin, and relevant to oxidative stress (OS), such as ROS, body antioxidant enzymes GPx and SOD. We also studied the ability of effective antioxidant agents alpha-lipoic acid (ALA), N-acetyl cysteine (NAC), and amifostine (AMI) added into culture to induce lymphocyte progression through the cell cycle, namely to enter into S phase. Additionally, we assessed the most significant clinical indexes of nutritional status such as body mass index and disease progression such as stage and ECOG-PS in the same cancer patient population. Cell cycle analysis of cultured unstimulated or PHA-stimulated PBMCs isolated from 120 cancer patients and 60 controls, with or without ALA, NAC, or AMI, was studied. The biological parameters relevant to cancer cachexia and OS were also studied. The addition of antioxidants ALA, NAC and AMI, enhanced significantly the progression through the cell cycle, namely from G0/G1 to S phase, of PBMCs isolated from cancer patients (+132%, +150% and +141%, respectively). The percentage of PHA-stimulated PBMCs of cancer patients entering S phase, which was significantly lower than that of controls, increased significantly to more than physiological level after coculture with antioxidants. ROS levels were significantly higher and GPx and SOD activities significantly lower in cancer patients than controls. Serum levels of IL-1 beta, IL-6, and TNFalpha were significantly higher and serum levels of IL-2 and leptin significantly lower in cancer patients than controls. Serum levels of C-reactive protein and fibrinogen were significantly higher in cancer patients than controls. A significant correlation was found in laboratory parameters only between serum levels of leptin and body mass index. Patients with advanced cancer thus exhibit both a high-grade OS and a chronic inflammatory condition. Antioxidant agents ALA, NAC, and AMI enhanced significantly the PBMCs progression through the cell cycle, thus providing evidence of their potential role in the functional restoration of the immune system in advanced cancer patients. Our data warrant further investigation with adequate clinical trials.

The impact of different antioxidant agents alone or in combination on reactive oxygen species, antioxidant enzymes and cytokines in a series of advanced cancer patients at different sites: correlation with disease progression.
In the present study we tested the ability of different antioxidant agents, used alone or in combination, to reduce the reactive oxygen species (ROS) levels and to increase the glutathione peroxidase (GPx) activity. Moreover, we tested the ability of such antioxidant agents to reduce the serum levels of proinflammatory cytokines IL-6 and TNFalpha. Fifty-six advanced stage cancer patients with tumors at different sites were included in the study: they were mainly stage III (12.5%) and stage IV (82.1%). The study was divided into two phases. In the 1st phase 28 patients were divided into five groups and a single different antioxidant agent was administered to each group. The selected antioxidant agents were: alpha lipoic acid or carboxycysteine-lysine salt, amifostine, reduced glutathione, vitamin A plus vitamin E plus Vitamin C. In the 2nd phase of the study 28 patients were divided into five groups and a combination of two different antioxidant agents was administered to each group. The antioxidant treatment was administered for 10 consecutive days. The patients were studied at baseline and after antioxidant treatment. Our results show that all single antioxidants tested were effective in reducing the ROS levels and three of them in increasing GPx activity, too. Among the combinations of antioxidant agents, three were effective in reducing ROS, while three were effective in increasing GPx activity (arm 4 was effective in both instances). Comprehensively, the "antioxidant treatment" was found to be effective both on ROS levels and GPx activity. Moreover, the antioxidant treatment was able to reduce serum levels of IL-6 and TNFalpha. Furthermore, a correlation was shown between the Eastern Cooperative Oncology Group Performance Status of patients and blood levels of ROS, GPx activity, serum levels of proinflammatory cytokines.

Cancer-related cachexia and oxidative stress: beyond current therapeutic options.
Cancer-related anorexia/cachexia syndrome is a complex phenomenon in which metabolic abnormalities, proinflammatory cytokines produced by the host immune system, circulating tumor-derived catabolic factors, decreased food intake and probably additional unknown factors all play different roles. This review examines the mechanisms of cancer-related anorexia/cachexia syndrome and the mainstays of its management. The two major options for pharmacological therapy have been progestational agents and corticosteroids. Agents currently under investigation are nonsteroidal anti-inflammatory drugs, N-3 fatty acids, branched-chain amino acids and thalidomide. On the basis of several previously published studies and clinical experience, an innovative treatment approach, which consists of an integrated nutritional and pharmacological treatment, has been developed. This approach, based upon multiple components each targeted at different factors involved, may be effective in both improving objective clinical symptoms, such as lean body mass, and subjective symptoms such as quality of life. A Phase II study has been initiated and Phase III study designed.

Reactive oxygen species, antioxidant mechanisms, and serum cytokine levels in cancer patients: impact of an antioxidant treatment.
OBJECTIVE: It has not been well established whether the oxidative stress found in cancer patients results from an increased production of oxidants in the body or from a failure of physiological antioxidant systems. To further investigate this question, we have assessed the blood levels of reactive oxygen species as a marker of free radicals producing oxidative stress and the most relevant of the physiological body enzymes counteracting reactive oxygen species, namely glutathione peroxidase and superoxide dismutase. We also investigated serum levels of proinflammatory cytokines and IL-2. All of these parameters were studied in relation to the most important clinical index of disease progression--namely, the Eastern Cooperative Oncology Group (ECOG) Performance Status (PS). We also tested the reducing ability of different antioxidant agents on reactive oxygen species levels by measuring the increase in glutathione peroxidase activity and the reduction of serum levels of IL-6 and TNF-alpha. PATIENTS AND METHODS: We carried out an open nonrandomized study on 28 advanced stage cancer patients (stage III, 10.7% and stage IV, 89.3%) with tumors at different sites. The patients were divided into 5 groups, and a different antioxidant treatment was administered to each group. The antioxidants were alpha lipoic acid 200 mg/day orally; N-acetylcysteine 1800 mg/day i.v. or carboxycysteine-lysine salt 2.7 g/day orally; amifostine 375 mg/day i.v.; reduced glutathione 600 mg/day i.v.; and a combination of vitamin A 30,000 IU/day orally, vitamin E 70 mg/day orally, and vitamin C 500 mg/day orally. The antioxidant treatment was administered for 10 consecutive days. RESULTS: We found that all but one of the antioxidants tested were effective in reducing reactive oxygen species levels, and two of them (cysteine-containing compounds and amifostine) had the additional effect of increasing glutathione peroxidase activity. Comprehensively, the antioxidant treatment was found to have an effect on both reactive oxygen species levels and glutathione peroxidase activity. The antioxidant treatment also reduced the serum levels of IL-6 and TNF-alpha. Patients in both ECOG PS 0-1 and ECOG PS 2-3 responded to antioxidant treatment.
