Internal validation of two nutritional screening tools in hospitalized children and adolescents with cancer.

Of the 111 patients, 75.7 % (n = 84) were classified as at nutritional risk by SCAN, and 34.2 % (n = 38) as at high risk by STRONGKids.

Patients at risk showed greater inadequacy in body composition measures and anthropometric indices.

There was an association between nutritional risk as classified by the screening tools and the reduction of lean mass reserves (p = 0.039) and adipose tissue (p = 0.017).

C-reactive protein was associated with nutritional risk only in STRONGKids, and with LOS only in SCAN.
