Figure 1.
Relationship between computed tomography defined lean body mass (LBM) and body surface area (BSA) in 776 colorectal cancer patients referred to a medical oncology service in northern Alberta, Canada. (A) Shows a weak relationship between BSA and LBM, R 2 = 0.5341. (B) Potential effect of body composition across quintiles of the ratio of LBM/BSA. Upper panel shows the potential variation in 5‐Fluorouracil (5FU)/kg LBM that would result in this population as a consequence of the variation in body composition, if all patients were to be administered 425 mg/m2 of 5FU (lower panel).
