Quantitative Assessment of Whole-Body Tumor Burden in Adult Patients with Neurofibromatosis
Figure 5
Relative tumor burden of patients younger and older than 40.
Patients older than 40 are represented in red; patients 40 or younger are shown in green. These two patient subpopulations differed significantly in relative tumor burden along the craniocaudal axis (p = 0·003 by permutation test) with patients 40 or younger having a higher percentage of tumor volume in the pelvis and legs than patients over 40.
