  • Recommendation(s)

    ONC: Head and neck cancer: Post-operative use of arginine

    Post-operative use of arginine-enhanced medical food supplements (MFS) or enteral nutrition (EN) to improve outcomes for patients with head and neck cancer is not recommended. Arginine-enhanced versus non-arginine-enhanced MFS and EN did not produce significant changes in weight and body composition in either well-nourished or malnourished subjects. Most evidence shows there is no impact of arginine-enhanced MFS or EN on immune function. Limited research reported that arginine-enhanced EN can improve post-operative complications and LOS in malnourished patients.

    Rating: Fair
    Imperative

    ONC: Head and neck cancer: Pre-operative use of arginine

    Pre-operative use of arginine-enhanced EN to improve outcomes for patients with head and neck cancer is not recommended. No significant improvement in clinical outcomes, nutritional status, or surgery-induced immune suppression was observed among malnourished compared to patients receiving a non-enhanced EN, or those who did not receive EN.

    Rating: Fair
    Imperative

    • Recommendation Narrative

      • Two positive quality and one neutral quality RCT suggested that the catabolic process that occurs in post-surgical head and neck cancer patients is not altered by arginine.
        • deLuis, Izaola et al, 2004 (positive quality) and deLuis et al,  2002 (neutral quality) provided a supplement enriched with arginine (.625g per 100ml) to head and neck cancer patients for an average of 21 and 22 days. Changes in weight from baseline were not significant in either or the arginine and control groups.
        • deLuis, Izaola et al,  2005 (positive quality) provided 1.2g arginine per 100 ml for 90 days to head and neck cancer patients. Changes in weight, FFM, FM, TSF, and AC were not significant.
      • One positive quality RCT (de Luis, Izaola et al, 2005) compared the use of an oral supplement enhanced with arginine vs. an omega-3 enhanced formula with head and neck cancer patients. Both groups experienced a significant improvement in plasma protein levels while only the omega-3 group experienced weight gain. There was no significant difference in fat-free mass between the two groups. There was no significant benefit of arginine over omega-3 fatty acid supplementation in this group of patients.
      • Two positive quality RCTs (de Luis, Izaola et al, 2004; de Luis, Arranz et al, 2005) found no significant differences in plasma proteins and immune parameters between head and neck cancer patients receiving arginine-enhanced vs. standard enteral formulas.
      • One neutral quality study (de Luis, Aller et al, 2002) found that fistula development was significantly less common among head and neck cancer patients receiving arginine-enhanced enteral feedings, otherwise no statistically significant differences were observed between those receiving arginine-enhanced vs. standard enteral formulas.
      • One positive quality RCT (Riso et al, 2000) compared the use of an arginine-enhanced enteral formula to a control isocaloric, isonitrogenous enteral formula in post-operative patients with head and neck cancer to measure immunologic and clinical outcomes. The study group receiving the arginine-enhanced formula experienced an improved post-operative immunological response, most notably in patients who were classified as malnourished prior to the start of the study. The malnourished group also experienced a decrease in both post-operative complications and LOS compared to the control group.
      • One positive quality RCT (Van Bokhorst-de van der Schueren et al, 2001) compared the use of an arginine-enhanced enteral formula to a standard enteral formula or no enteral feedings. No significant differences in clinical outcomes, nutritional status, or surgery-induced immune suppression were observed between the three groups.

    • Recommendation Strength Rationale

      • Based on five positive quality and one neutral quality RCTs,  conclusion statements are grade II and III.
