Cancer cachexia Anorexia, chronic nausea, asthenia,
psychological stress. Poor survival and decreased tolerance
to both radiotherapy and chemotherapy. No evidence : nutritional or
pharmacological intervention improve survival.
Exception : GI obstruction from malignancy.
Lancet Oncolo 2000;1:138-47
Goals Ideal : reverse syndrome
completely eliminate tumor mass impossible
Reasonable : Improving general comfort. Relieving of symptoms : anorexia,
nausea, asthenia. Improve level of functioning.
Lancet Oncolo 2000;1:138-47
Management approach Nutrition Pharmacological intervention Psychological and behavioral therapy
Lancet Oncolo 2000;1:138-47
Nutrition Nutritional counseling improve the daily
caloric intake. Maximize oral intake by allowing the patient
flexibility in type, quantity and timing if meals. Disease progresses decrease nutritional
support. Adequate mouth care and small amount of ice
chips or sips of cold beverages may be adequate
In dehydration : use hypodermoclysis
Lancet Oncolo 2000;1:138-47
Hypodermoclysis• A family member can do hypodermoclysis at home after one lesson from the doctor• Using hypodermoclysis, a family member can give the sick person about 90 ounces of fluid a day by giving 45 ounces of fluid in two different places . American Family Physician Nov

Lancet Oncolo 2000;1:138-47
Corticosteroid Mechanism
Inhibition of synthesis and/or release of proinflammatory cytokines (TNF-α,IL-1), anorexigenic mediators(leptin, CRF, serotonin)
Enhance NPY levels in hypothalamus.

Lancet Oncolo 2000;1:138-47
Corticosteroid Improving appetite, food intake,
sensation of well-being, performance status.
No significant weight gain. Dose : 20-40 mg of prednisolone Risk : peptic ulcer, etc.
Lancet Oncolo 2000;1:138-47
Progesterone Mechanism
Stimulate NPY in the hypothalamus
Modulation of Ca channel in VMH(satiety center)
Inhibition of proinflammatory cytokines

Lancet Oncolo 2000;1:138-47
Progesterone Improve appetite, caloric intake, sensation
of well-being. Significant weight gain (mostly fat) . Dose : megestrol acetate 160-1600 mg ,
optimum dose : 800 mg Response can be seen in 1 week. Risk : thromboembolism, breakthrough
bleeding, peripheral edema, hyperglycemia, hypertension, Cushing syndrome, alopecia, adrenal insufficiency.
Lancet Oncolo 2000;1:138-47
Metoclopramide Mechanism
Antidopaminergic drug
Central antiemetic Gastroprokinetic :
improve gastric emptying

Lancet Oncolo 2000;1:138-47
Metoclopramide Improve in appetite, food intake. Dose : 10 mg before meals and
bedtime. Risk : minimal
Lancet Oncolo 2000;1:138-47
Cyproheptadine Mechanism
Antiserotoninergic RCT
mild increase appetite, food intake.
No weight gain. Risk : sedation
X
Lancet Oncolo 2000;1:138-47
Hydrazine sulphate Mechanism
Inhibit gluconeogenesis
Pilot study improve appetite and
nutritional status. No weight gain.
Substantial side effects and deterioration of QOL scales

Lancet Oncolo 2000;1:138-47
Thalidomide Mechanism
Inhibit production of TNF-α
Pilot study Improve appetitie,
well-being, nausea, insomnia
X
Lancet Oncolo 2000;1:138-47
Melatonin Mechanism
Decrease circulating concentration of TNF-α
Preliminary studies Weight loss > 10%
fewer than best supportive care
X
Lancet Oncolo 2000;1:138-47
Beta-adrenoreceptor agonist Clenbuterol
Mechanism Decrease protein
catabolism. Positive effect on
muscle mass in tumor-bearing rats.
Risk : nervousness, tachycardia, tremor, headache.
X
Lancet Oncolo 2000;1:138-47
Anabolic steroid Mechanism
Decrease protein catabolism
RCT Less effective than
dexamethasone/megestrol acetate in appetite and nutritional variables.
X
Lancet Oncolo 2000;1:138-47
Growth hormone Mechanism
Stimulate muscle protein synthesis.
No trial in cancer cachexia. X
Lancet Oncolo 2000;1:138-47
Cannabinoid Mechanism
Stimulate appetite No trial in cancer
cachexia. Risk :
somnolence, confusion, perceptual disturbance.
X
Lancet Oncolo 2000;1:138-47
NSAIDs Mechanism
Inhibit the production of cytokine
Stimulate appetite Preliminary
studies : Ibuprofen Weight gain Decrease
production of CRP

Lancet Oncolo 2000;1:138-47
EPA(Eicosapentanoic acid) Omega 3 fatty acid
Mechanism Inhibition of
lipolysis and muscle protein degradation
Eicosapentanoic acid decrease production of IL-6
