Abstract
Previously we reported that intermittent intraperitoneal administration of ornithine decarboxylase-inducing factor (ODC factor), interleukin 1alpha (IL-1alpha), and tumor-necrosis factor-alpha (TNF-alpha) to normal mice induced biological changes in the hosts which included changes in the pattern of expression of pyruvate kinase (PK) isozymes in the liver and hypertrophy of the spleen. In the study reported here, we investigated the chronic and combined effects of these factors on hepatic enzymes using alzet microosmotic pumps implanted in the subcutis of the backs or abdominal cavities of mice. Continuous administration of ODC factor and recombinant human IL-1alpha (rhIL-1alpha) reduced the activity of L-type PK, which is a glycolysis-related enzyme in the liver, and induced the activity of M2-type PK, a known marker of liver dedifferentiation. Serine dehydratase (SDH) and tyrosine aminotransferase (TAT), enzymes associated with amino acid metabolism, were not significantly influenced at the examined concentration. The simultaneous continuous infusion of ODC factor and rhIL-1alpha or rhTNF-alpha caused alterations in the patterns of expression of PK isozyme activity profiles and reduced overall PK activity. SDH and TAT activities were also significantly induced. Moreover, mice treated with these combined factors displayed many other metabolic changes normally associated with cancer cachexia. These findings suggest that the tumor-derived ODC factor and cytokines such as IL-1alpha and TNF-alpha might function synergistically in the metabolic perturbations observed in Ehrlich ascites tumor bearers.

Abstract
Cancer cachexia is a frequent complication observed in patients with malignant tumors. Although several decades have passed since the first focus on the metabolic dysfunction's associated with cancer, few effective therapeutic interventions have been successfully introduced into the medical armamentarium. The present study thoroughly reviews the basic pathophysiology of cancer cachexia and the treatment options already investigated in that field. Experimental and clinical studies were evaluated individually in order to clarify the intricate alterations observed in tumor-bearing patients. The difficulties in introducing sound and effective nutritional support or metabolic manipulation to reverse cancer cachexia are outlined in this review.

Abstract
A large number of observations point towards cytokines, polypeptides released mainly by immune cells, as the molecules responsible for the metabolic derangements associated with cancer-bearing states. Indeed, these alterations lead to a pathological state known as cancer cachexia which is, unfortunately, one of the worst effects of malignancy, accounting for nearly a third of cancer deaths. It is characterized by weight loss together with anorexia, weakness, anemia, and asthenia. The complications associated with the appearance of the cachectic syndrome affect both the physiological and biochemical balance of the patient and have effects on the efficiency of the anticancer treatment, resulting in a considerably decreased survival time. At the metabolic level, cachexia is associated with loss of skeletal muscle protein together with a depletion of body lipid stores. The cachectic patient, in addition to having practically no adipose tissue, is basically subject to an important muscle wastage manifested as an excessive nitrogen loss. The metabolic changes are partially mediated by alterations in circulating hormone concentrations (insulin, glucagon, and glucocorticoids in particular) or in their effectiveness. The present study reviews the involvement of different cytokines in the metabolic and physiological alterations associated with tumor burden and cachexia. Among these cytokines, some can be considered as procachectic (such as tumor necrosis factor-alpha), while others having opposite effects can be named as anticachectic cytokines. It is the balance between these two cytokine types that finally seems to have a key role in cancer cachexia.

Abstract
Cancer anorexia-cachexia syndrome (CACS), which is characterized by progressive weight loss (WL) and anorexia (A), is present in 50% of advanced cancer patients and in 80% of terminally ill cancer patients. One of the most controversial aspects of CACS is its oetiopathogenesis; experimental studies have identified certain cytokines [Tumour necrosis factor alpha (TNF-alpha), interleukin 1 (IL-1), interleukin 6 (IL-6), and gamma interferon (gamma-IFN)] as possible co-factors in the onset of the syndrome. The aim of our study was to investigate the correlation between serum levels of circulating cytokines and severity of CACS. The following series of parameters was identified in 61 patients with advanced and terminal cancer: stage of disease; Karnofsky performance status (KPS) and clinical symptoms; biohumoral, anthropometric and immunological situation; level of circulating cytokines. All these parameters were evaluated for a possible link with WL/A. Our data do not show any significant correlation between circulating cytokines and WL/A. A direct correlation was identified between WL/A and nausea (P = 0.03 and P < 0.001, respectively) whereas inverse correlations were observed for both factors as regards arm circumference (P < 0.001 for both), wrist circumference (P < 0.001 for both), KPS (P < 0.001 and P = 0.003, respectively) and creatinine (P = 0.005 and P = 0.03, respectively). Other biochemical factors, such as haemoglobin, haematocrit, glycaemia, prealbumin, sodium and chlorine were also correlated with at least one of two clinical parameters in question. Unexpected results were seen in the increases in CD20 and CD4 and in the CD4/CD8 ratio. Serum levels of these cytokines do not, therefore, appear to be critical in the onset of CACS. On the contrary, our findings confirmed the clinico-laboratory picture that is characteristic of CACS. If we consider the possibility that CACS is provoked by an aspecific response of the host's defence mechanisms against prolonged neoplastic attack, the increase in CD4 (helper lymphocytes) could be linked to the persistent response.

Abstract
A review on the possible involvement of tumor necrosis factor-alpha (TNF) in cachexia is presented. While this cytokine is definitely linked to sepsis and tumor-associated weight loss in some experimental models, other cytokines, such as interleukin-6 (IL-6) or interferon-gamma (IFN-gamma), alone or in combination with TNF, may also play an important role in the development of cachexia.

Abstract
The possible role of cytokines in the development of cancer cachexia was reviewed from the literature. Tumor necrosis factor (TNF)-alpha, interleukin (IL)-1, IL-6, interferon (IFN)-gamma and leukemia inhibitory factor (LIF) can elicit many but not all host changes seen in cancer cachexia, including loss of appetite, loss of body weight, and the induction of acute-phase protein synthesis. However, these cytokines are not always demonstrated in the circulation of the cancer patients. The inability to detect circulating cytokines may be due to their low rate of production, their short half-life and rapid clearance from plasma, or their mode of action (autocrine or paracrine). Different cytokines are induced to stimulate the same response. This is very different from hormonal regulation, where a hormone acts on a cell directly through a specific receptor without depending on other mediators. Specific antibodies including anti-IFN-gamma, anti-TNF and anti-IL-6 antibodies, as well as the cyclooxygenase inhibitor indomethacin, have been used to reverse cancer cachexia. Overlapping physiologic activities make it unlikely that a single substance is the sole cause of cancer cachexia. It is hoped that further investigation on other cytokines and their possible relationships with hormones will help to clarify the mechanisms of cancer cachexia in the near future.

Abstract
In several studies, the anabolic hormones insulin-like growth factor-1 (IGF-1) and insulin attenuated several metabolic changes associated with cancer cachexia. In the present study, we evaluated the effect of these hormones on the cachexia associated with colon-26 (C-26) tumor. Healthy age-matched and tumor-bearing mice were treated with two daily doses of IGF-1 (50 micrograms/kg in toto), or insulin (1 U in toto). Determinants of cachexia were body and tumor weight, epididymal fat pad and serum glucose concentrations. Neither IGF-1 nor insulin treatment had a significant effect on the cachectic parameters of C-26-bearing mice. These hormones were biologically active, being capable of inducing weight gain in hypophysectomized mice and hypoglycemia, respectively. Although IGF-1 and insulin have been used to treat cancer-related weight loss, the research presented here suggests that the beneficial effect of these hormones is not universal.

Abstract
Some monocytic cytokines are important immune regulators. We have investigated cytokine production by monocytes and the blood levels of IL-1 beta, IL-6, TNF alpha, and TGF beta, in patients with obstructive jaundice. The supernatant from LPS stimulated monocytes from jaundiced patients released significantly increased quantities of TNF alpha by both bioassay and radioimmunoassay (RIA) (12.4 +/- 2.5 fmol/mL and 32.6 +/- 8.3 fmol/mL, respectively, for jaundice, compared with 1.6 +/- 0.3 fmol/mL and 2.4 +/- 0.5 fmol/mL respectively for controls, and also of IL-6 (54.8 +/- 5.0 fmol/mL in jaundice compared with 35.6 +/- 5.0 fmol/mL for controls). The production of IL-1 beta and TGF beta by stimulated monocytes was unchanged. Jaundiced patients had significantly higher plasma TGF beta, but TNF alpha and IL-1 beta were below the limits of detection. The highest monocyte TNF alpha and IL-6 levels were seen in malignant disease patients, especially those with a poor immediate prognosis. We conclude that the production of some cytokines by monocytes is up-regulated in patients with obstructive jaundice.

Abstract
The mechanisms leading to the development of cancer cachexia are still poorly understood. Recently, cytokines such as interleukin 1 and tumour necrosis factor-alpha have been involved as mediators of the tissue wasting consequent to tumour growth. The rat ascites hepatoma Yoshida AH-130 is a highly anaplastic tumour that causes in the host an early and marked depletion of both the skeletal muscle and the adipose tissue, mainly accounted for by a hypercatabolic state. Profound hormonal alterations and the release of tumour necrosis factor-alpha and interleukin 1 by the tumour cells likely concur in forcing the metabolic balance towards the catabolic side [1]. In order to possibly achieve the correction of this wasting condition, the AH-130 bearing rats were administered a daily s.c. dose of interleukin 1 receptor antagonist (IL-1ra; 2 mg/kg). This factor, however, was completely ineffective in either inhibiting tumour proliferation or in preventing the consequent tissue depletion and protein hypercatabolism. These observations suggest that interleukin 1 is not important, at least in this model system, for either the development of cachexia or tumour growth.

Abstract
Anorexia, net proteolysis of skeletal muscle and consumption of body fat are hallmarks of the cachexia syndrome associated with chronic disease states. While inanition contributes to cachexia, this wasting diathesis has little in common with simple starvation. The cachexia syndrome is characterized by progressive weight loss and depletion of lean body mass in excess to that resulting from comparable caloric restriction. Accelerated mobilization and consumption of host protein stores from peripheral tissues occurs to support gluconeogenesis and acute phase protein synthesis [1, 2]. In contrast, simple starvation is associated with a relative sparing of lean tissue with the preferential consumption of fat. While the clinical manifestations of cachexia are readily apparent, identification of the specific mechanisms responsible for the development of cachexia remains an enigma. In recent years, interest has focused on the role that the immune system plays in the development of cachexia. Investigators initially hypothesized that the chronic production of two inflammatory cytokines, tumour necrosis factor alpha (TNF alpha) and/or interleukin-1 (IL-1), could explain the host non-specific responses resulting in cachexia [3-5]. Other pro-inflammatory cytokines, including interleukin-6 (IL-6) [6, 7] and interferon-gamma [8, 9], have been more recently proposed to be involved in this complex process. Although no consensus exists for the exclusive role of any one cytokine in the pathogenesis of cachexia, there is growing acceptance that the progression of cachexia results in part from the inappropriate release of one or more pro-inflammatory cytokines [10, 11]. In the present review, the current role of TNF alpha as a mediator of cachexia is examined.

Abstract
Eleven metastatic cancer patients were studied during three different regimens of immunotherapy with interleukin-2 (IL-2) and/or interferon alpha (IFN alpha): group A received 4 days of IL-2 i.a. infusion (n = 3), group B IFN alpha s.c. during 5 days (n = 4), followed on day 3 by 5 days of a continuous IL-2 i.v. infusion, and group C had 4 days of IL-2 i.v. infusion together with s.c. IFN alpha on days 1 and 4 (n = 4). Soluble tumor necrosis factor receptors (sTNFR) p55 and p75 and TNF alpha concentrations in serum were analyzed before therapy and daily during 8 days of the first therapy cycle. sTNFR was measured by radioimmunoassay. sTNFR p55 increased in all patient groups from a baseline value of 5.2 +/- 0.9 ng/ml to a maximum of 13.6 +/- 1.2 ng/ml by days 3-4 (P = 0.003). sTNFR p75 increased from 7.6 +/- 1.1 ng/ml to peak values of 30.1 +/- 2.6 ng/ml in groups A and B (P = 0.02). In group C the sTNFR p75 response was weak (NS). In group B, the increase of both p55 and p75 occurred only after addition of IL-2 to IFN alpha. TNF alpha increased weakly during treatment with IFN alpha alone (group B); it rose strongly during IL-2 and the combined treatment (groups A-C) from 8 +/- 2 pg/ml to 115 +/- 13 pg/ml (P = 0.003). In group B, it reached the maximum 24 h after addition of IL-2 to IFN alpha and decreased thereafter. There was a significant relationship between TNF alpha and sTNFR p55 or sTNFR p75 in groups A and C, (P = 0.001), but not in group B. Group C was also investigated during the third therapy cycle. The increase of sTNFR p75 was stronger (P = 0.01) and that of TNF alpha weaker than in the first cycle; the sTNFR p55 response was similar in both cycles. In conclusion sTNFR p55 and p75 are rapidly induced during IL-2 and IL-2+ IFN alpha treatment, the increase of sTNF receptors parallels or exceeds that of TNF alpha and may influence the immunomodulatory effects of TNF alpha during cytokine therapy.

Abstract
This study was designed to investigate the effect of tumor necrosis factor-alpha (TNF) on the control of food intake in rat. The specific aims were: a) to evaluate the effects of central (ICV) or peripheral (IP) microdoses of TNF on food intake; b) to show that the TNF-induced anorexia results from a direct action of the mediator on the central nervous system; c) to demonstrate that the anorexic activity of TNF is not due to nonspecific malaise. In the first experiment, ICV administration (0.5-4.0 micrograms) of recombinant-murine tumor necrosis factor-alpha (rmTNF) significantly reduced food intake in a dose-dependent manner. The maximal effect (-66%) was observed 5 h after a 4.0 micrograms dose. In contrast, rm TNF did not affect feeding behavior when injected IP, indicating that the anorexic activity was centrally mediated. The estimated DE50 was 2.0 micrograms/rat by the ICV route. In the second experiment, the place conditioning paradigm was used to show that TNF administered ICV at 2.0 micrograms/rat did not induce aversive or deleterious effects as compared to naltrexone given IP at the equi-anorectic dose 5.0 mg/kg. It was concluded that TNF reduces food intake in rats by a direct action on the central nervous system.

Abstract
Asthenia is a very common symptom of patients with advanced cancer, but its investigation is hindered by a lack of suitable validated measuring instruments. The goal of the present study was to construct and validate a questionnaire for the study of asthenia in cancer patients, as well as to establish correlations with other symptoms and physiological and biochemical parameters. A group of 31 patients with advanced cancer and a control group of 30 healthy volunteers were examined. The proposed questionnaire, based on visual analogue scales, questions with categorical answers and on the hospital anxiety and depression scale was validated by comparing results of the patient and control groups, by the test/retest method and by comparison with the evaluation of an observer. Correlation with various physiological and biochemical parameters was performed. The questionnaire distinguished well among the patients and control groups. VAS of asthenia proved quite stable over a period of 5 days. Correlations of asthenia with lack of appetite, the hospital anxiety and depression scale, weight, heart rate and serum cortisol levels could be established. No significant correlation between asthenia and various serum markers of inflammation and cytokines, including C-reactive protein, tumour necrosis factor, interleukin-1, and interleukin-2 receptors, could be found. The proposed questionnaire for evaluation of asthenia could be validated in a patient sample of limited size and a simplified questionnaire based on visual analogue scales is being developed for further investigations.

Abstract
Early and severe loss of body weight associated with pronounced tissue changes developed in rats transplanted with a fast-growing ascites hepatoma (Yoshida AH-130). The protein content showed an early and marked fall in the skeletal muscle, while in the liver it transiently increased 4 days after implantation then declined to values lower than in control animals. Protein loss in gastrocnemius muscle and liver resulted mainly from enhancement of protein catabolism (Tessitore L. et al., Biochem. J., 241: 153-158, 1987). In contrast to the tumour-bearing rats, in the pair-fed animals the initial body weight was maintained, while the protein mass decreased sharply in the liver and moderately in the gastrocnemius muscle. In host animals total plasma protein decreased during the period of tumour growth, while both triglycerides and total cholesterol markedly increased. Glucose remained unchanged even when overt cachexia had developed. The total free amino acid concentration in the plasma of tumour-bearing rats decreased slightly by day 4 and returned to values close to those of controls in the late stages of tumour growth. By contrast, in the pair-fed controls the plasma levels of triglycerides and particularly of total free amino acids and glucose decreased over the whole experimental period, whereas total protein and cholesterol were unchanged. Marked perturbations in the hormonal homeostasis developed early after tumour transplantation. The plasma levels of glucagon, corticosterone and catecholamines rose sharply, while those of insulin and thyroid hormones decreased. Furthermore, high plasma concentrations of prostaglandin E2 (PGE2) and tumour necrosis factor (TNF) were observed over the whole experimental period. IL-1-like activity, TNF and PGE2 were released in vitro from AH-130 cells. These data suggest that the systemic effects of AH-130 tumour on the host rat reflected the interplay of a complex network of factors, including classical hormones and cytokines, all of which likely concur in enhancing tissue protein catabolism.

Abstract
Tumor necrosis factor-alpha (TNF-alpha) production by unstimulated and lipopolysaccharide (LPS)-stimulated peripheral monocytes has been studied in 17 acute myeloid leukemia (AML) patients, 54 AML patients in complete remission (AML-CR), 9 acute lymphoblastic leukemia (ALL) patients and 13 ALL patients in complete remission (ALL-CR). TNF-alpha production by the unstimulated monocytes in ALL patients (n = 6, mean: 6.6 +/- 4.9 u/ml) was higher than that of normal controls (n = 13, 0.9 +/- 0.7 u/ml), AML patients (n = 14, 2.0 +/- 2.1 u/ml) and AML-CR patients (n = 21, 1.4 +/- 1.2 u/ml). TNF-alpha production by the LPS-stimulated monocytes of the AML-CR patients (n = 54, 12.4 +/- 13.4 u/ml) was significantly higher than that of the normal controls (n = 21, 3.5 +/- 2.5 u/ml) and the AML patients (n = 17, 2.6 +/- 2.4 u/ml), p < 0.01, but there were not any significant differences among the AML-CR patients and the ALL patients or the ALL-CR patients. We separated the AML-CR patients into 3 groups, depending on the length of their remission, and found that AML-CR patients with longer than 6 months (M) but less than 60 M (n = 21, 15.7 +/- 16.9 u/ml) and the patients with a remission longer than 60 M (n = 11, 18.2 +/- 15.9 u/ml) had significantly higher TNF-alpha production than that of the controls.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
There is, at present, considerable interest in the possible role for the proinflammatory cytokines, tumor necrosis factor-alpha, interleukin-1, interleukin-6, and interferon-gamma in the pathogenesis of cancer cachexia. Indirect evidence for such a role is based on the observation that chronic administration of many of these cytokines, either alone or in combination, can reproduce the myriad of host responses seen in experimental and human cancer cachexia. Elevated plasma levels of tumor necrosis factor-alpha, interleukin-2, and interferon-gamma have rarely been detected in patients or experimental animals with cancer, although interleukin-6 levels appear to correlate with tumor progression in animal models. The strongest evidence for a causal role for cytokines has come from rodent studies in which tumor-bearing animals have been passively immunized with antibodies directed against individual cytokines. Several groups have shown modest but significant improvements in food intake and lean tissue retention with antibodies directed against tumor necrosis factor-alpha, interleukin-1, interleukin-6, and interferon-gamma. However, there has been no consistent finding that one cytokine is universally involved in cancer cachexia in histologically distinct tumor models. One ominous finding in several tumor models has been that the endogenous production of cytokines appears to support tumor growth. Such findings raise the intriguing possibility that these cytokines, although contributors to tissue wasting and anorexia, may also serve the tumor as either direct or indirect cell growth factors.(ABSTRACT TRUNCATED AT 250 WORDS)

Abstract
In this study we evaluated the clinical response of 12 patients with malignant melanoma and renal cell carcinoma (RCC) following administration of recombinant human interleukin-2 (rhIL-2) by continuous infusion. Serum samples taken before, during and following sequential courses of IL-2 were assayed for the presence of tumour necrosis factor alpha (TNF-alpha) IL-1 alpha, IL-6 and interferon gamma (IFN-gamma) and the presence or changes in these cytokines were examined with respect to clinical response data: our results did not show any direct correlation between the parameters measured and clinical outcome. In addition, peripheral blood mononuclear cells (PBMC) derived from 3 RCC patients were cultured in a serum-free environment and the resulting supernatants assayed for the production of these cytokines and compared to the corresponding serum levels. During one or more courses of treatment only 1 patient, who had metastatic bone disease, demonstrated detectable serum TNF-alpha; serum IL-6 levels were elevated in a proportion of all patients studied and a sustained IL-6 response occurred in a patient who had complete disease remission; IL-1 alpha was detected in the serum of 3 RCC patients; IFN-gamma could not be detected in any serum sample tested. Cytokine levels in sera and supernatants derived from 3 RCC patients were compared but no correlation was found: TNF-alpha and IL-6 were shown to be present at much higher concentrations in supernatants when compared to sera whereas the levels of IL-1 alpha were almost undetectable. This lack of correlation is probably due to the presence of "interfering" proteins in sera which either depress or enhance the ability to detect cytokines in sera using enzyme immunoassays.

Abstract
We determined the circulating level of bioactivity for skeletal muscle proteolysis-inducing factors (PIF) in the blood samples from cancer patients whose body weight loss was greater than 10%. The level of bioactivity was estimated by measurement of tyrosine release from isolated 1at diaphragm muscles incubated with an ultrafiltered fraction of plasma or serum proteins containing molecules from 0 to 25 kDa in molecular weight. Significant levels of bioactivity were detected in 25 of the 50 cancer samples. No activity was found in 18 of the samples from healthy human blood donors. The ability of 13 of the cancer samples to induce muscle proteolysis was significantly inhibited by incubation of muscles in presence of indomethacin (10 microM). The neutralisation of 12 of the cancer samples with the antibodies to recombinant human interleukin-1 (IL-1), alpha and beta forms, partially abrogated the activity in five samples. These results suggest that the accelerated breakdown of proteins induced by the cancer plasma factors is at least in part mediated by IL-1 in cooperation with other active factors not yet defined. Additionally, we have shown that the increased breakdown of proteins induced by PIF in the crude supernatant derived from activated mouse peritoneal macrophages is prevented by the treatment of muscles with either indomethacin or quin-2 (1 microM). These observations provide indirect evidence for a possible causal relationship between the production of PIF and the body-weight loss of cancer patients.

Abstract
The peptide tumour necrosis factor-alpha (TNF-alpha) is a central mediator of the host response. Identifying where and when TNF-alpha is produced may give insights into its potential role in various pathophysiological states. This paper describes a quantitative analysis of TNF-alpha expression in peripheral blood monocytes (PBM) at the single cell level. A pilot study has been undertaken, using this method to assess TNF-alpha expression in PBM from healthy volunteers and cancer patients. We also report mildly elevated serum TNF-alpha levels in the cancer patients, using an immunoradiometric assay (IRMA) sensitive to 1 pg/mL of recombinant TNF-alpha. The results of this preliminary investigation suggest that TNF-alpha production may be altered in cancer patients.

Abstract
Cancer patients (n = 106) and non-cancer subjects (n = 96) were classified as weight stable (n = 70) or weight-losing (n = 132). Cancer patients had elevated resting energy expenditure (REE) compared with either weight-losing (23.6 [0.4] vs. 20.5 [0.5] kcal/kg per day, P less than 0.001) or weight-stable controls (22.0 [0.6] vs. 17.9 [0.4], P less than 0.001). Cancer patients had increased fat oxidation irrespective of weight loss (1.24 [0.07] vs. 0.87 [0.04] mg/kg per min; 1.07 [0.04] vs. 0.78 [0.04], P less than 0.001). Elevated energy expenditure was counter-regulated by a decrease in thyroid hormones. Abnormal liver function had no impact on REE in either group. Heart rate was the most powerful factor for prediction of high energy expenditure in both patients and controls. Elevated energy expenditure was related to the increased heart rate in cancer patients in a significantly higher proportion than that in controls. Increased metabolic rate is a significant component behind weight loss in cancer disease, independent of malnutrition and an elevated adrenergic state may be a likely explanation.
