Treatment
Treatment
Evidence-based resources to support implementation of the treatment recommendations in the COSA Cancer-related Malnutrition and Sarcopenia Position Statement.
Position statement recommendations
All people with cancer-related malnutrition and sarcopenia should have access to the core components of treatment including individualised medical nutrition therapy, targeted exercise prescription and physical activity advice, and physical and psychological symptom management.
Treatment for cancer-related malnutrition and sarcopenia should be individualised, in collaboration with the MDT, and tailored to consider multi-morbidities and meet needs at each stage of cancer treatment.
Core components of treatment of cancer-related malnutrition and sarcopenia
Patients who are at risk of malnutrition or sarcopenia or diagnosed with malnutrition or sarcopenia should be referred to a dietitian and physiotherapist/exercise physiologist for nutrition and exercise therapy. They should also have support from the multidisciplinary team to identify and manage any physical or psychosocial symptoms. However, not all health services will be able to accommodate this. If you don’t have access to the appropriate support services, the resources below can be used to support your patient.
Medical Nutrition Therapy
Nutrition interventions are most beneficial when they are proactive, initiated early, and continued through recovery, preferably as part of multimodal interventions that also include exercise therapy.
All patients should have a comprehensive assessment and receive individualised nutrition counselling and support to manage nutrition impact symptoms and optimise dietary intake. If nutrition support is required, the route will vary according to the clinical situation, but may include oral nutrition supplements, enteral nutrition or parenteral nutrition. Advice relating to the nutrition prescription for cancer-related malnutrition and sarcopenia can be found below.
Treating or preventing malnutrition
Important nutrients to consider:
Energy
- Aim for a minimum of 105kJ/kg/d – 125kJ/kg/day (Muscaritoli et al, 2021)
Protein
- Aim for a minimum of 1.0 to 1.5 grams/kg/day in protein. (Muscaritoli et al, 2021)
Vitamins and minerals
- Vitamins and minerals should be supplied in accordance with the recommended daily allowance. The use of high dose micronutrients should be discouraged in the absence of specific deficiencies. (Muscaritoli et al, 2021)
Treating or preventing low muscle mass
Important nutrients to consider:
Energy
- Aim for a minimum of 105kJ/kg/d – 125kJ/kg/day (Muscaritoli et al, 2021).
Protein and amino acids
- Aim for a minimum of 1.0 to 1.5 grams/kg/day in protein (Muscaritoli et al, 2021). There is emerging research investigating the benefit of higher protein intakes to support muscle protein synthesis (Ford et al, 2024; Bauer et al, 2019).
- Leucine is a branched-chain amino acid that has been shown to support increased muscle protein synthesis (Prado et al, 2022).
- b-hydroxy-b-methylbutyrate (HMB) is a metabolite of leucine that stimulates muscle protein synthesis and inhibits muscle protein breakdown (Prado et al, 2022).
Vitamin D
- A fat-soluble vitamin that plays an important role in bone and muscle health (Prado et al, 2022).
n-3 PUFAs
- The anti-inflammatory effect of n-3 polyunsaturated fatty acids have been shown to promote muscle anabolism (Muscaritoli et al, 2021; Prado et al, 2022).
Other emerging nutrients for consideration include creatine, carnitine, b-alanine, polyphenols for their positive effects on muscle anabolism, muscle strength and muscle function (Prado et al, 2022).
Other considerations:
Exercise Therapy
- For medical nutrition therapy to be optimally effective, it needs to occur alongside exercise intervention Bauer et al, 2019).

Exercise Therapy
Exercise training complements nutrition interventions in the treatment of cancer-related malnutrition and sarcopenia. Specifically, targeted exercise interventions promote improvements in muscular strength, physical function, and body composition including the preservation or accumulation of lean mass independent of changes in body weight. An individually prescribed multimodal exercise program (including targeted aerobic, resistance, and balance training) at moderate to high intensity is recommended. In individuals with or at risk of sarcopenia, interventions should emphasise resistance exercise incorporating exercises for major muscle groups.
The Exercise and Sports Science Australia (ESSA) position statement provides valuable guidance in the prescription of exercise in cancer management (Hayes et al, 2019). The recommended approach, summarised in Figure 1, should be considered by clinicians endorsing or delivering exercise to patients with or at risk of sarcopenia and malnutrition. Optimal Exercise prescription will be determined by patient assessment, identification and consideration of general and cancer-specific health issues and their contribution to risk of morbidity and/or mortality, and subsequent patient-driven goals. Individualised exercise prescription, which includes the provision of behaviour change advice and support, is needed to ensure greatest benefit.
Key components of exercise therapy
Resistance exercise
- Resistance exercise promotes improvements in muscular strength, muscle hypertrophy, bone health and physical function. Examples include exercises using body weight, resistance bands, machine weights, and free weights.
- 2-3 sessions/week, involving 2-3 sets of exercises for each major muscle group at moderate to hard intensity is safe and recommended for most patients (Hayes et al, 2019; COSA 2017).
Aerobic exercise
- Aerobic exercise promotes improvements in cardiorespiratory fitness, exercise tolerance, and cardiometabolic health. Examples include walking, cycling, rowing, dancing, and swimming.
- 150 minutes accrued over 5-7 days/week at moderate (40-59% heart rate reserve) to vigorous (60-89% heart rate reserve) intensity is safe and recommended for most patients (Hayes et al, 2019; COSA 2017).
Balance exercise
- Balance exercise reduces the risk of falls and promotes improvements in/maintenance of physical function and independence. Examples include exercises challenging balance, agility, coordination, gait and proprioception.
- 2-3 sessions of 20-30 minutes/week per week is safe and recommended for most patients (Hayes et al, 2019) .
Exercise prescription and progression should align with patient goals, symptom burden, physical capacity, and health history and may evolve as these change across the cancer treatment trajectory.
