Background A randomized controlled trial previously conducted in radiation oncology patients demonstrated that nutrition intervention had a beneficial impact on body weight, nutritional status, and quality of life compared with standard practice, but it did not report on dietary intake data.

Objective To determine the impact of nutrition intervention compared with standard practice on dietary intake in outpatients receiving radiotherapy.

Design Prospective, randomized, controlled trial.

Subjects Sixty consecutive radiation oncology outpatients (51 men and nine women; age 61.9±14 years [mean±standard deviation]).

Setting Australian private radiotherapy facility.

Intervention Patients were randomly assigned to receive either nutrition intervention (n=29) (nutrition counseling following the American Dietetic Association [ADA] medical nutrition therapy [MNT] protocol for radiation oncology) or standard practice (n=31) (general nutrition talk and booklet).

Main Outcome Measure Dietary intake (protein, energy, fiber) assessed at baseline and at 4, 8, and 12 weeks after starting radiotherapy.

Statistical Analyses Repeated-measures analysis of variance done on an intention to treat basis.

Results The nutrition intervention group had a higher mean total energy (P=0.029) and protein intake (P<0.001) compared with the standard practice group. Mean intake per kilogram of body weight for the nutrition intervention group ranged from 28 to 31 kcal/kg/day compared with 25 to 29 kcal/kg/day for the standard practice group (P=0.022). The nutrition intervention group had a higher mean protein intake (1.1 to 1.3 g/kg/day) compared with the standard practice group (1.0 to 1.1 g/kg/day) (P=0.001). Although the change in fiber intake between the groups was not significant, there was a trend in the anticipated direction (P=0.083).

Conclusions Intensive nutrition intervention following the ADA MNT protocol results in improved dietary intake compared with standard practice and seems to beneficially impact nutrition-related outcomes previously observed in oncology outpatients receiving radiotherapy. The ADA MNT protocol for radiation oncology is a useful guide to the level of nutrition support required.

Citation counts are sourced monthly from Scopus and Web of Science® citation databases.

These databases contain citations from different subsets of available publications and different time periods and thus the citation count from each is usually different. Some works are not in either database and no count is displayed. Scopus includes citations from articles published in 1996 onwards, and Web of Science® generally from 1980 onwards.
