Patients undergoing myeloablative conditioning regimens and autologous stem-cell transplantation (asct) are at high risk of malnutrition. This randomized study aimed to determine if early nutrition support (commenced when oral intake is less than 80% of estimated requirements) compared with usual care (commenced when oral intake is less than 50% of estimated requirements) reduces weight loss in well-nourished patients undergoing high-nutritional-risk conditioning chemotherapy and asct. In the 50 well-nourished patients who were randomized, the outcomes evaluated included changes in weight and lean body mass (mid-upper arm circumference), length of stay, time to hemopoietic engraftment, and quality of life (Memorial Symptom Assessment Scale - Short Form). On secondary analysis, after exclusion of a single extreme outlier, both groups demonstrated significant weight loss over time (p = 0.0005). Weight loss was less in the early nutrition support group at time of discharge (mean: -0.4% ± 2.9% vs. -3.4% ± 2.6% in the usual care group, p = 0.001). This difference in weight was no longer observed at 6 months after discharge (mean: -1.0% ± 6.8% vs. 1.4% ± 6.1%, p = 0.29). In practice, an early start to nutrition support proved difficult because of patient resistance and physician preference, with 8 patients (33%) in the control group and 4 (15%) in the intervention group not commencing nutrition support when stipulated by the study protocol. No significant differences between the groups were found for other outcomes. In well-nourished patients receiving asct, early nutrition support maintained weight during admission, but did not affect other outcomes. Interpretation of results should take into consideration the difficulties encountered with intervention implementation.
