  2. DEFINITION OF CACHEXIA Cachexia is a multifactorial syndrome characterized by tissue wasting, loss of body weight, particularly of lean body (muscle) mass and to a lesser extent adipose tissue, metabolic alterations, fatigue, reduced performance status, very often accompanied by anorexia leading to a reduced food intake: it accompanies the end stage of many chronic diseases

  3. UP- to- date DEFINITION OF CACHEXIA Multi-factorial syndrome defined by an ongoing loss of skeletal muscle mass (with or without loss of fat mass) that cannot be fully reversed by conventional nutritional support and leads to progressive functional impairment. Agreed diagnostic criteria are: weight loss>5% or >2% in individuals already showing depletion of body weight (BMI<20 kg/m2) or skeletal muscle (sarcopenia). Assessment for classification and clinical management should include the following domains: anorexia/reduced food intake, catabolic drive, muscle mass and strength, functional and psychosocial impairment.

  4. ETIOLOGY OF WEIGHT LOSS IN THE ELDERLY Reduced basal hunger, dysgeusia, decreased gastric emptying time, failure to adjust food intake after a period of overfeeding or underfeeding NORMAL AGING Hyperthyroidism, hyperparathyroidism and hypoadrenalism ENDOCRINE DISORDERS Theophylline, lithium, digoxin, chemotherapy, antibiotics, etc….

  30. COMBINED APPROACH To date, attempts at cancer cachexia therapy with a variety of single interventions have had limited success. The main features of cachexia (progressive loss of muscle mass and function) have been shown to be only minimally influenced by the nutritional or pharmacological tools currently available. However, a combination of dietary, nutritional, and pharmacological approaches to normalize the metabolic milieu may be capable of reversing advanced cancer-related symptoms that affect patient Quality of Life References: Support Care Cancer 2010;18:1–9. Oncologist 2010;15:119–21.

  31. Strategies for intervention in cachexia Treatment should address the fundamental issues of reduced food intake and abnormal abnormalities Fearon KC. ClinNutr 2012; 31:577-582

  32. From July2002 to January 2005, 44 patients were enrolled. Of these, 39 completed the treatment and were assessable. Body weight, LBM and appetite increased significantly from baseline. There was an important decrease of proinflammatory cytokines IL-6 and TNFalpha 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-5DVAS, 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.

  33. Medroxyprogesterone acetate (MPA) 500 or Megestrol Acetate (MA) 320mg/day Arm 1 Pharmaco-nutritional support with EPA 2-3 cartons/day Arm 2 random Basic treatment poliphenols (300 mg/day) + antioxidant agents alpha lipoic acid 300 mg/day, carbocysteine 2.7 g/day (Fluifort, Dompè), Vitamin E 400 mg /day (Sursum, Abiogen), Vitamin A 30000 IU and Vitamin C 500 mg/day + Arm 3 L-carnitine 4 g/day Arm 4 Thalidomide 200 mg/day Arm 5 Combination of the above agents The most effective treatment in terms of all three primary efficacy endpoints, i.e. LBM, REE and fatigue, and the secondary endpoints appetite, IL-6, GPS, and ECOG PS score was the combination regimen that included all selected agents. The Oncologist 2010;15:200–211

  34. A total of 104 advanced-stage gynecological cancer patients were enrolled and randomly assigned to receive either: megestrol acetate (MA) plus L-carnitine, celecoxib, and antioxidants (arm 1) or MA alone (arm 2). The treatment duration was 4 months. The combination arm was more effective than arm 2 as regards: LBM, REE, fatigue, and global QoL. As for the secondary efficacy endpoints, patient appetite increased, and ECOG PS decreased significantly in both arms. The inflammation and oxidative stress parameters IL-6, TNF-α, CRP, and ROS decreased significantly in arm 1, while no significant change was observed in arm 2.

  35. PATIENT-CENTERED OUTCOME Fearon KC. ClinNutr 2012; 31:577-582

  36. IT IS EVIDENT THAT A MULTIDISCIPLINARY APPROACH IS NEEDED TO PREVENT CACHEXIA AND MANAGE THE ASSOCIATED SYMPTOMS TO IMPROVE QUALITY OF LIFE FOR PATIENTS BENESSERE FISICO Disturbi indotti dalla malattia, Effetti collaterali dei trattamenti STATO FUNZIONALE Capacita’ di lavorare, di utilizzare il tempo libero, di badare a sé stesso QUALITA’ DI VITA STATO PSICOLOGICO Ansia, depressione, aggressività, stima e sicurezza di sé, modificazioni dello schema corporeo BENESSERE SOCIALE Relazione con i familiari Relazione con i curanti, ruolo sociale, ECC.

  37. Eur J Cancer 2008; 4 4: 1 1 2 4 –1 1 3 2 We are aware that multimodal therapies for cancer cachexia should ideally be introduced within a context of the “best supportive care”, which includes optimal symptom management and careful psychosocial counseling.
