FIGURE 2. Kaplan–Meier survival curves of NSCLC patients with bone marrow hypermetabolism (BM SUV > 1.7) on 18F-FDG PET vs. patients with normal bone marrow metabolism. BM SUV is normalized for lean body mass (lbm). Median survival of patients with bone marrow hypermetabolism was significantly shorter than that of NSCLC patients with normal bone marrow metabolism (151 vs. 799 d; P = 0.00006, log-rank test). BM = bone marrow.
