Preoperative primary tumor SUVmax on PET/CT correlates with Breslow thickness and is associated with survival in melanoma: A retrospective cohort study

Supplementary Table I. Demographics and tumor characteristics of 31 patients with residual primary melanoma tumors that underwent PET/CT.

Supplementary Figure 1.
Subgroup analysis according to melanoma stage. (a) Patients with early-stage melanoma (Stage I-II) show a moderately positive correlation between SUVmax and Breslow thickness (r=0.585). (b) Patients with advanced-stage melanoma (Stage III-IV) show a strong correlation between SUVmax and Breslow thickness (r=0.618).

Supplementary Figure 2.
(a) Receiver operating characteristic (ROC) curve analysis identifying an SUVmax cutoff of 4.945 for predicting overall survival in melanoma patients. (b) Kaplan-Meier survival analysis demonstrating significantly worse survival rates in patients with SUVmax ≥ 4.945 compared to those with SUVmax < 4.945 (p=0.04, by Generalized Wilcoxon method).
