nausea/vomiting • weight loss • anorexia • depletion of both fat and muscle tissue SYMPTOMS OF CANCER-RELATED CACHEXIA • anemia • immunodepression • fatigue • resistance to antineoplastic treatments and enhancement of their side effects
INCIDENCE OF CANCER CACHEXIA/ANOREXIA SYNDROME Incidence of weight loss in cancers of different sites (LavianoA, et al. Nature Clinical Practice Oncology (2005) 2, 158-165) Approximately 2/3 of patients who die with advanced cancer suffer from cancer cachexia 20% of cancer patients die from effects of malnutrition rather than from direct effects of malignancy Marion M. Support Line. 1998;20:3 Ottery FD. Cancer Pract. 1994;2:123 DeWys WD, et al. Am J Med. 1980;69:491
PATHOGENESIS OF CACS Cancer-induced cachexia is invariably associated with the presence and growth of the tumor. The main factors leading to CACS anorexia decreased food intake metabolic changes (cytokines) increased REE. In addition, the competition for nutrients between tumor and host leads to an accelerated starvation state characterised by severe metabolic disturbances and hypermetabolism resulting in an increased energetic inefficiency
METABOLIC CHANGES:CACHEXIA VS. STARVATION Adapted from Kotler DP. 2000. Ann Intern Med. 133:622
CHANGES OF ENERGY METABOLISM • In cancer patients in advanced stage of disease, a characteristic deregulation of energy metabolism is frequently observed: • increased energy expendituredue to tumor growth and activation of the immune system • intake of energetic substrates (especially glucose) due to symptoms such as anorexia, nausea and vomiting • cytokine-induced metabolic alterations (insuline resistance, etc)
CHANGES OF GLUCOSE METABOLISM IN CANCER CACHEXIA PROTEIN AND LIPID STORES GLYCEROL + FREE FATTY ACIDS a) GLUCONEOGENESIS CORI CYCLE b) hyperglicaemia c) IMPAIRED GLUCOSE TOLERANCE hypoglicaemia d) INSULIN RESISTANCE
CHANGES OF PROTEIN METABOLISM IN CANCER CACHEXIA muscle and liver sinthesis of albumin, etc and liver synthesis of acute phase proteins (APP=C Reactive Protein and Fibrinogen) serum levels of Proteolysis Inducing Factor (PIF) selective muscle wasting
CHANGES OF LIPID METABOLISM IN CANCER CACHEXIA • Lipolysis (fatty acids beta oxidation) Lipogenesis Free fatty acids turnover (FFA) synthesis of free fatty acids (FFA) lipoproteinlipase activity Hypertrigliceridaemia
HYPERMETABOLISM In cancer cachexia the decreased caloric intake is not accompanied by a drop in energy expenditure. Hyltander et al, in a wide population study, have showed that cancer patients have a higher resting energy expenditure as compared with normal controls.

CANCER-RELATED ANOREXIA/CACHEXIA SYNDROME AND OXIDATIVE STRESS: AN INNOVATIVE APPROACH BEYOND CURRENT TREATMENT Giovanni Mantovani, Clelia Madeddu, Antonio Macciò, Giulia Gramignano, Maria Rita Lusso, Elena Massa, Giorgio Astara and Roberto Serpe Department of Medical Oncology, University of Cagliari, Italy Cancer Epidemiol Biomarkers and Prev 2006; 15:1030-1034 Cancer Epidemiol Biomarkers and Prev 2004; 13:1651-1659
AIM OF THE STUDY • CACS and Oxidative Stress (OS) play a key role in the progression and outcome of the neoplastic disease: their appearance and worsening are very important negative prognostic factors in the progression of cancer. • Aim of the study wasto test the EFFICACY AND SAFETY • of an integrated treatment based on diet, p.o. pharmaconutritional support, and drugs in a population of advanced cancer patients with CACS/OS. • The efficacy was assessed in terms of: • - clinical response • improvement of nutritional and functional variables • changes of laboratory variables (as indicators of CACS/OS) • and improvement of quality of life (QL). • The ultimate goal of our study should be that of translating the results obtained on CACS/OS symptoms found in advanced cancer patients into a prevention trial in a population of individuals at risk of developing CACS/OS.
STUDY DESIGN- PHASE II STUDY The trial design was: AN OPEN NON RANDOMIZED PHASE II STUDY On the basis of the Simon two-stage design for phase II studies, considering as P0 (i.e. non effective treatment) a total response 40% of patients, and as P1 (i.e. effective treatment) a total response 60% of patients, the treatment has to be considered effective if at least 18/34 patients demonstrate a response in the first stage, while in the second stage 21/39 patients should demonstrate a response. Mantovani G, et al Cancer Epidemiol, Biomarkers and Prev, 2004, 13:1651-9 and 2006,15:1030-4
PATIENT ELIGIBILITY CRITERIA: • 18 to 80 years old • hystologically confirmed tumors of any site especially cancers inducing early CACS (head and neck and gastrointestinal cancer) • patients with the following nutritional characteristics: • 1) patients who had lost at least 5% of ideal or pre-illness body weight in the last 3 months (clinical CACS); • 2) and/or with abnormal values of proinflammatory cytokines, ROS and antioxidant enzymes predictive of the onset of CACS • patients treated with either antineoplastic therapy with curative or palliative intent or supportive care • patients with a life expectancy > 4 months. Mantovani G, et al Cancer Epidemiol, Biomarkers and Prev, 2004, 13:1651-9 and 2006,15:1030-4
PATIENT EXCLUSION CRITERIA: • pregnancy • significant comorbidities • Impaired food intake due to mechanical obstruction • medical treatments inducing significant changes of patient metabolism or body weight such as enteral or parenteral nutrition, corticosteroids, insulin, or any other drug potentially capable of influencing body weight. Mantovani G, et al Cancer Epidemiol, Biomarkers and Prev, 2004, 13:1651-9 and 2006,15:1030-4
TREATMENT PLAN On the basis of several of our previously published studies and our clinical experience we have developed an innovative approach which consists of an integrated nutritional and pharmacological treatment: • 1. diet with high poliphenols content (400 mg) obtained by alimentary sources (onions, apples, oranges, red wine, or green tea) or supplemented by tablets per os; • 2.pharmaco-nutritional support enriched with n-3 PUFA containing EPA and DHA; • 3. oral progestagen:medroxyprogesterone acetate 500 mg/day; • 4. antioxidant treatment with alpha lipoic acid 300 mg/day + carboxycysteine lysine salt 2.7 g/day + vitamin E 400 mg/day + vitamin A 30000 IU + vitamin C 500 mg/day. • Selective COX-2 inhibitor: Celecoxib 200 mg/day orally • The planned treatment duration is 16 weeks. Mantovani G, et al Cancer Epidemiol, Biomarkers and Prev, 2004, 13:1651-9 and 2006,15:1030-4
RATIONALE FOR SELECTED AGENTS 1. The polyphenols, in particular quercetin have been included for their high activity as antioxidants. 2. The oral dietary supplement has the objective to integrate the energetic/proteic intake with the supplementation of n-3 PUFA, which are able to inhibit cytokine production (TNFa). 3. The treatment with medroxyprogesterone acetate has the objective to inhibit the cytokine production and to act positively on patients cenestesis: our previous experimental and clinical experience with MPA supports this choice. 4. The selected antioxidant treatment has been demonstrated effective in reducing blood levels of ROS and increasing blood levels of physiological antioxidant enzymes in a series of our published papers. 5. The COX-2 selective inhibitor Celecoxib has been chosen for its ability, demonstrated both in experimental and in clinical studies, to inhibit cancer-related inflammatory mediators (PGE2), angiogenesis and therefore cancer progression as well as CACS causal factors.
