Methods: In this prospective, cross-sectional, multicenter study, demographic,<br />

oncological, and nutritional data were collected in all consecutive mCRC patients<br />

in three hospitals. Computed tomography (CT) images were analyzed using<br />

Slice-O-Matic software V4.3 (Tomovision) to evaluate cross-sectional areas (cm 2 )<br />

of muscle tissue (MT), visceral adipose tissue (VAT), and subcutaneous adipose<br />

tissue (SAT). The 3 rd lumbar vertebra (L3) was chosen as a reference, since L3<br />

and whole-body measurements are linearly related. Indexed on height, MT, VAT<br />
