EPEC– Oncology Education in Palliative and End-of-life Care – Oncology Module 3b: Symptoms – Anorexia / Cachexia
Anorexia / Cachexia . . . Cachexia – wasting syndrome • Decreased lean tissue • Diminished performance status • Altered resting energy expenditure • Diminished appetite
Anorexia / Cachexia Epidemiology in cancer: • Incidence varies with site • Incidence increases with stage
Anorexia / Cachexia Impact: • ≥ 5% weight loss associated with poor prognosis • Trend toward lower chemotherapy response rates • Anorexia associated with poor prognosis • Diminished function and quality of life • Adversely affects caregivers MacDonald N, et al.

Key points • Pathophysiology • Assessment • Management
Pathophysiology • Chronic inflammation • Metabolic changes • Lipolytic / proteolytic substances • Hormonal changes • Role of neurotransmitters • Cytokine impact on hypothalamus Todorov P, et al.

Assessment • Appetite / weight loss history • Reversible causes • Physical signs of wasting • Biochemical markers • Radiographic studies as indicated
… AssessmentReversible causes of weight loss: • Psychological factors • Mucositis • Nausea / vomiting • Constipation • Early satiety • Malabsorption • Pain • Endocrine • Comorbid conditions • Social / economic
Management . . . • Treat comorbid conditions • Educate, support • Provide favorite foods / nutritional supplements / counseling • Treat reversible causes (e.g., early satiety, mucositis)
