Clinical bottom line
Nutritional support in palliative care for advanced cancer patients aims to alleviate eating-related distress, maintain quality of life, and potentially mitigate cachexia, but evidence for survival benefit remains limited. Individualized nutritional counseling and symptom-targeted interventions can improve patient and family well-being. Multimodal approaches integrating psychosocial support are essential given the complex interplay of metabolic, psychological, and social factors in advanced cancer nutrition (Ueshima et al., 2023; Amano et al., 2018).
What the evidence shows
Ueshima et al. (2023) conducted a systematic review and meta-analysis demonstrating that nutritional counseling in incurable cancer patients can improve nutritional intake and quality of life metrics, although effects on survival are inconsistent. Counseling tailored to patient preferences and symptom burden is critical.
Amano et al. (2018) highlight the prevalence of eating-related distress among patients and families in palliative settings, underscoring the importance of addressing psychosocial dimensions alongside physical nutritional support. Their survey identified a strong perceived need for nutritional interventions to reduce distress.
PREVOST et al. (2012) found that nutritional support correlates with improved quality of life in cancer patients undergoing palliative care, emphasizing symptom management such as appetite loss and nausea as key targets.
Bozzetti et al. (2020) discuss chemotherapy-induced sarcopenia, noting that early nutritional interventions may attenuate muscle loss and functional decline, although evidence in advanced disease stages is limited.
Mulazzani et al. (2021) review nutritional support indications in gastroesophageal cancer, illustrating the continuum from perioperative to palliative systemic therapy and the need for adaptive strategies as disease progresses.
Amano et al. (2018) further developed questionnaires to evaluate eating-related distress, facilitating better assessment and individualized care planning.
Caveats and uncertainty
Most studies are heterogeneous in design, with variable endpoints and small sample sizes.
Survival benefit from nutritional support in advanced cancer remains unproven.
Optimal timing, modality (oral, enteral, parenteral), and intensity of nutritional interventions are not standardized.
Psychosocial factors and patient goals of care significantly influence outcomes but are challenging to quantify.
Risk of overfeeding or complications from artificial nutrition must be balanced against potential benefits.
How this may change practice
Clinicians should prioritize early, individualized nutritional counseling integrated with symptom management to address eating-related distress.
Routine assessment tools for nutritional status and psychosocial distress can guide tailored interventions.
Multidisciplinary collaboration involving dietitians, palliative care specialists, and psychosocial support teams is essential.
Focus on quality of life and patient-centered goals should guide decisions on artificial nutrition in advanced disease.
Further research is needed to define best practices and develop standardized protocols in palliative nutrition.
