Early nutritional intervention is key in head and neck cancer, according to new ASPEN guidelines

The American Society for Parenteral and Enteral Nutrition (ASPEN) has recently published new clinical guidelines on nutritional management in adults with head and neck cancer, emphasizing the urgent need for early, individualized and proactive nutritional intervention throughout the patient journey.

Patients with head and neck cancer are at particularly high risk of malnutrition due to the combined effects of the disease and its treatment. Difficulties in chewing and swallowing, reduced appetite, and treatment-related toxicities significantly compromise oral intake, placing these patients at high nutritional risk.

Systematic screening and continuous monitoring

One of the first key pillars emphasized in the guidelines is the importance of malnutrition screening at the first clinical visit and throughout treatment, ensuring that patients at risk are identified and treated without delay.

Regular follow-up by nutrition professionals is another essential component. ASPEN recommends weekly consultations with a dietitian during treatment, followed by continued monitoring after therapy to maintain nutritional status and quality of life.

Early nutritional intervention as a core pillar of care

When oral intake becomes insufficient, the guidelines recommend initiating early nutritional support, including early enteral nutrition when necessary to prevent deterioration in nutritional status and improve clinical outcomes

In the postoperative setting, ASPEN recommends starting nutritional intake within 24 hours after surgery, reinforcing the role of early intervention can support recovery and reduce complications.

At this stage, special attention is given to meeting energy and protein requirements to preserve lean body mass and improve treatment tolerance:

• Energy: ≥30 kcal/kg/day
• Protein: 1.2–1.5 g/kg/day

Multidisciplinary and individualized approach

The guidelines also stress the importance of continuous follow-up by nutrition professionals, with frequent reviews—ideally weekly during active treatment—and ongoing monitoring after therapy to maintain nutritional status and quality of life.

In addition, ASPEN highlights that nutritional care in head and neck cancer should be multidisciplinary, involving dietitians, physicians, language therapists, and other healthcare professionals. This collaborative approach allows interventions to be adapted to each patient’s clinical condition, symptoms, and treatment plan.

With these new recommendations, ASPEN reinforces the growing recognition that nutrition is not only supportive care but an integral component of cancer treatment. Early, structured, and individualized nutritional strategies can play a decisive role in improving outcomes, reducing complications, and enhancing patients’ quality of life.
