Management of Cancer Cachexia: ASCO Guideline.

Area of Science:

• Oncology
• Clinical Nutrition
• Evidence-Based Medicine

Background:

• Cancer cachexia is a complex multifactorial syndrome characterized by involuntary weight loss and muscle atrophy.
• It significantly impacts patient quality of life, treatment tolerance, and survival in advanced cancer.
• Current management strategies require evidence-based optimization.

Framework:

• Systematic review of randomized controlled trials (RCTs) and systematic reviews of RCTs.
• Literature search of PubMed and Cochrane Library (1966–October 2019).
• ASCO Expert Panel convened for evidence review and recommendation formulation.

Implementation:

• Dietary counseling, with or without oral nutritional supplements, showed potential for increasing body weight but with limited evidence.
• Pharmacologic interventions including progesterone analogs and corticosteroids were associated with improvements in appetite and/or body weight.
• Other interventions like exercise demonstrated no benefit or insufficient evidence.

Implications:

• Dietary counseling can be offered for patient and caregiver support in managing cachexia.
• Routine use of enteral feeding tubes and parenteral nutrition is not recommended.
• While no pharmacological intervention is standard care, progesterone analogs and short-term corticosteroids may be considered for appetite and weight gain.
